            <p>Description</p>
            <p>(The species description is based on the tomographic data, NIGP175852). Carapace (Figs 8, 9): LV overlaps RV along the dorsal and ventral margins. Dorsal margin with greatest height at about 1/3rd of length, tapering down in straight line and same angle to anterior and posterior ends. Hinge well-developed, straight, between highest point and posterior end. Both anterior and posterior margins nearly equicurvate, with the latter curved much narrower than the former, but lacking an acute angle or pointed tip. Fusiform in dorsal view with greatest width at mid-length. Ventral margin slightly concave at mid-length. Calcified inner lamella relatively narrow at free margin, slightly broader at posterior end, and broadest at anterior end. Central muscular scars not visible. Normal pores scattered over smooth surface.</p>
            <p>Soft Body (Figs 10 - 13): A1 (Figs 10B, 12A, B, N, O, 13A) with eight segments. Segments 1 and 2 fused forming large base, with two long setae originating ventro-distally on segment 2. Segment 3 short and asymmetric, sub-triangular, with ventral extension. Segment 4 connected to segment 3 with ventral inclination. Segments 4 to 8 all separate (not fused) and rectangular, with decreasing widths. Presence of setae confirmed for segments as figured. Setae on segment 8 at least as long as figured, possibly longer.</p>
            <p> A2 (Figs 10A, 12 C, D, P, 13A) Segment 1 (coxa) subrectangular, segment 2 (basis) elongate and carrying long ventro-apical seta. Knee between segment 2 and 3. Segment 3 (first endopodal segment) very similar to segment 2 in shape and length, also carrying ventro-apical seta. Exopod not confirmed, but aesthetasc Y present. Natatory setae not observed in male, but at least 2 natatory setae present in one of the  female’s A2 (Fig. 12P); their exact point of origin at segment 3 is unclear. Segments 4 and 5 possibly fused, since clear segmental boundary could not be confirmed. Their length approximately half the length of segment 3. Apically with at least three claws (G1, G2, G3). Segment 6 small with at least one claw apically (GM or Gm). </p>
            <p>Md (Figs 10D, 12E, F, Q, 13B) Masticatory process of coxa with teeth (total number uncertain). Palp consisting of 4 separate segments and remarkably straight (i.e., not bent ventrally towards mouth). Segment 1 (basis) with vibratory (branchial) plate on dorsal edge (no setae observed), and two thick setae ventrally, one at medium-length of the segment, the other more distally, but still at a considerable distance to segment 2. Shape of this segment obliquely trapezoidal due to angulation on dorsal margin. Segment 2 nearly square-shaped, with at least three setae apically (one dorsally, two ventrally). Segment 3 more elongate, with shoulders distally towards segment 4. On these shoulders, at least 5 setae confirmed (2 dorsally, 3 ventrally). Segment 4 much thinner than proximal segments, distally at least one thick seta or claw present.</p>
            <p>Mxl (Fig. 10C) Protopod with branchial plate (no setae confirmed), three masticatory lobes (endites 1-3) and palp. Palp possibly two-segmented, as dorsal seta might indicate. Distal claws and/or setae not confirmed.</p>
            <p>L5 Male (Figs 10E, 12G, H, 13C): no setae on protopod confirmed. Palp (endopod) truncated, possible finger-like process of this clasping organ not observed. Masticatory process with several distal setae. Female (Figs 10F, 12R): masticatory process and palp preserved with no detail.</p>
            <p>L6 (Figs 10G, 12I, J, S) Walking leg. Segment 1 small, segment 2 elongate with seta e distally. Segments 3 and 4 separate, not fused. Segment 3 with seta f distally, segment 4 with no seta g observed. Segment 5 with long claw h2.</p>
            <p>L7 (Figs 10H, 12K, L, T, U, 13D) Cleaning leg, directed dorsally. Segment 1 (basis) with setae d1 and d2 present. Segment 2 (first endopodal segment) long, with distal seta e. Segments 3 and 4 separate, not fused. Segment 3 with seta f, segment 4 with seta g distally. Segment 5 short, nearly quadrate; distally long claw h2 and long reversed seta h3 present.</p>
            <p>Ur ramus (Figs 11A, B, 12M, V, 13E) Relatively stout and straight, with two relatively long terminal claws of similar length preserved (approx. half the length of the posterior edge of the ramus). Posterior and anterior setae not observed. UR attachment simply branched.</p>
            <p>HP (Figs 11C, 13F) roughly triangular in lateral view, with no differentiation of lobes observed. Greatest length of HP nearly a quarter of carapace length.</p>
            <p>Female genital lobes (Figs 11B, 13G) formed as spindle-shaped projections towards posterior and extending nearly to the posterior-most end of the soft body (i.e. basis of the UR).</p>
            <p>Remarks.</p>
            <p> Electrocypria burmitei gen. et sp. nov. possesses relatively long setae on A1, as well as at least 2 natatory setae on A2, however, the latter are only preserved partly, and possibly not at their full lengths. It is therefore impossible to evaluate the swimming capability of this species. </p>
            <p> The straight appearance of the Md palp results from segment 2 being nearly square-shaped and not as wedge-shaped as is often the case in other  Cypridoidea . None of the L5s is completely preserved in either specimen and it remains unclear how the male claspers look in  E. burmitei gen. et sp. nov. While L6 is formed as a walking leg with a long distal claw and segments 3 and 4 not fused, L7 is formed as a 5-segmented cleaning leg with setae e, f and g present, as well as long terminal h2 and h3 setae/claws. The holotype shows a linear breakage in its LV, in parallel to the dorsal margin, as well as minor breaking marks in its RV. The external pressure of the resin seems to have squeezed body liquid out of the animal on the LV into the surrounding resin (Figs 8A, B, 9A, B). </p>

            <p> Electrocypria gen. nov.</p>
            <p>Type species.</p>
            <p> Electrocypria burmitei sp. nov. </p>
            <p>Etymology.</p>
            <p> Name referring to  ‘electrum’ , the Latin term for amber + cypria, a common epithet in candonid ostracods. </p>
            <p>Diagnosis.</p>
            <p> Small ostracods of the family  Candonidae , with subrectangular (male) to trapezoidal (female) lateral carapace shape. Dorsal margin with greatest height at about 1/3rd of length, tapering down in straight line from there towards anterior and posterior ends. Anterior end curved broadly, posterior end with narrow curve, but not pointed. Calcified inner lamella not broad. Female higher than male. Fusiform in dorsal view with greatest width at mid-length. A1 with segments 3 to 8 separate (not fused). Natatory setae present on A2. L7 with segments 3 and 4 clearly separate, each without dorso-apical, marginal spiny processes (hooks). Terminal segment short (not longer than wide), carrying a robust and long claw h2 and a long reflexed seta h3. UR with anterior and posterior claws of the same length. </p>
            <p>Remarks.</p>
            <p> The new genus is excluded from the  Ilyocyprididae and  Notodromadidae by its carapace morphology, and from the most  Cyprididae subfamilies by its lack of a terminal pincer on the L7 (see, e.g., Horne et al. 2019). We are aware of some extant cypridid genera of the subfamily  Cypridopsinae with non-pincer L7 (e.g.,  Neocypridopsis Klie, 1940;  Paranadopsis Almeida et al., 2021;  Cyprettadopsis Savatenalinton, 2020) or incomplete pincer structure (e.g.,  Brasilodopsis Almeida et al., 2021) but all of these share the cypridopsine character of a reduced UR, unlike  Electrocypria which has a fully developed UR. There is also the genus  Batucypretta (subfamily  Batucyprettinae ) with a much reduced UR and lacking the L7 pincer, considered by its describing authors (Victor and Fernando 1981) to be transitional to the  Cypridopsinae . The cyprid genus  Zonocypretta De Deckker, 1981 (subfamily  Bradycypridinae ) lacks the L7 pincer and has a fully-developed UR, but differs from  Electrocypria by virtue of other features including marginal septa in the valves. </p>
            <p> Within the three subfamilies of the  Candonidae ,  Electrocypria is best allocated to the  Paracypridinae , foremost because of the natatory setae observed in the female specimen. Such natatory setae are not present in the  Candoninae . The third subfamily,  Cyclocypridinae , can be excluded by the valve morphology and shape, as well as by the cyclocypridine L7 morphology with segments 3 and 4 being fused, and the terminal segment carrying a long reflexed seta h3 and two short h1 and h2 setae distally. The genus  Electrocypria therefore belongs to the subfamily  Paracypridinae , which is currently subdivided into three tribes, these being the marine  Paracypridini and the marine to brackish  Thalassocypridini and  Renaudcypridini . Although the carapace morphology may point to the  Thalassocypridini ,  Electrocypria cannot be allocated to this tribe because of its L7 morphology, with segments 3 and 4 not being fused, a short terminal segment and its two long h setae distally. In the  Thalassocypridini , segments 3 and 4 of L7 are fused, the terminal segment is long and bears only a long reflexed seta, while the other two h setae are short.  Electrocypria does not qualify as a  Renaudcypridini because of the lack of a unique feature of this tribe: the strong, spiny processes situated dorso-distally on both segments 3 and 4 of L7. In  Electrocypria the dorsal edges of these segments are clearly smooth. Also,  Renaudcypridini possess a well-developed tooth in the antero-ventral area of the inner lamella in the LV, complemented by a defined socket on the inner lamella of the RV (Wouters 2001) - characters that could not be observed in  Electrocypria . Species of the third tribe,  Paracypridini , typically show wide calcified inner lamellae with narrow vestibula and broad fused zones with radial pore canals in their well-calcified carapaces. These characters are not present in  Electrocypria . The genera of the  Paracypridini are more diverse in their soft body features than those of the  Thalassocypridini and  Renaudcypridini , as shown in the detailed review of anatomical features in the  Paracypridinae by Maddocks (1992). The anatomy of A1 with its varying degrees of segment fusion and the variable combination of L7 features in the different genera may serve as examples. However, none of these mosaic patterns of characteristics fits to those observed in the type species of  Electrocypria . Due to the valve morphology, combined with the lack of congruence in important soft body features with any genus of the  Paracypridini , we refrain from attributing  Electrocypria to this tribe. Consequently, we cannot allocate the genus  Electrocypria to any of the currently accepted three tribes of the  Paracypridinae . </p>

            <p> Myanmarcypris hui Wang et al., 2020</p>
            <p>Figs 1, 2, 3, 4, 5, 6, 7</p>
            <p>Material.</p>
            <p> 31 specimens, 5 of which were analyzed using 3D X-ray microscopy: adult male, holotype (BA19005-1) - L = 600  µm , H = 356  µm , W ≈ 290  µm ; paratypes: adult female, (BA19005-2) - L = 609  µm , H = 382  µm , W ≈ 300  µm ; A- 2 juvenile (BA19005-3) - L = 400  µm , H = 261  µm , W ≈ 175  µm ; A- 3 juvenile (BA19005-4) - L = 313  µm , H = 204  µm , W ≈ 161  µm ; A- 4 juvenile (BA19005-5) - L = 226  µm , H = 156  µm , W ≈ 120  µm ; material not tomographed: BA19005-11-36 (Suppl. material 1: Fig. S1). </p>
            <p>Emended description.</p>
            <p>Carapace (Figs 1, 2): Adults small, in lateral view subtriangular. Female with higher and more pointed dorsal peak than male. In dorsal view, anterior and posterior ends blunt, not pointed. Valves thick and strongly reticulate, with prominent transverse muri, except for the dorsal region, which is smooth. In adults, a conspicuous antero-ventral lateral node present on each of the valves (Figs 1E, J, 2A). Antero-dorsally with smooth eye-spot (Fig. 1F). Normal pores distributed all over the valves except dorsal area. LV overlaps RV along dorsal and ventral margins. Hinge adont. Well-developed calcified inner lamella in adult carapaces, broader anteriorly than posteriorly, and anteriorly with inner list (Fig. 2C). Ventral margin of calcified inner lamella with conspicuous anterior tooth in LV and corresponding socket in RV, and two smaller posterior teeth in LV with corresponding sockets in RV, the latter much less developed than anterior socket (Fig. 2B). No central muscle scars preserved. Preserved juveniles show similar carapace ornamentation as adults except for A-4 stage, which is smooth (Fig. 1).</p>
            <p>Soft Body (Figs 3 - 6): A1 (Figs 3A, B, O, P, 4A, 5B) with eight segments. Segments 1 and 2 fused forming large base, with two setae of unknown length originating dorso-median and long setae situated ventro-distally on segment 2. Only a little more distal, ventro-basally on segment 3, prominent Rome Organ with inflated tip (Figs 4A, 5B). Segment 3 short and sub-triangular. Segment 4 longer than twice its width. Segments 5 to 8 not fused and rectangular, with decreasing widths. Presence of setae confirmed for segments as figured. Setae at least as long as figured, possibly longer.</p>
            <p>A2 (Male) (Figs 3C, D, 5C) Segment 1 (coxa) small, with 2 setae ventrally. Segment 2 (basis) elongate and carrying long ventro-apical seta. Segment 3 (first endopodal segment) elongate, with aesthetasc Y (ventro-median) and four natatory setae ventro-apically on the interior side of the appendage. Natatory setae possibly not complete and maximum length not known. Segments 4 and 5 possibly fused, together around half the length of segment 3. Apically with at least one seta subapical-exteriorly and three claws. Segment 6 small with at least one claw apically. Preservation of female A2 not sufficient for detailed chaetotaxy (Fig. 3Q, R).</p>
            <p>Md (Figs 3E, F, S, T, 5A) Masticatory process of coxa too poorly preserved to describe morphology. Palp consisting of 4 separate segments and straight (i.e., not bent ventrally). Branchial plate not observed. Segment 1 (basis) with two setae ventrally, one at medium-length of the segment, the other more distally. Third seta originating on interio-apical margin. Shape of this segment subrectangular with angulation on dorsal margin. Segment 2 square-shaped, with at least five setae apically (2 dorsally, 3 ventrally). Segment 3 rectangular with at least 5 setae confirmed 3 dorsally, 2 ventrally). Segment 4 much thinner than proximal segments, rectangular, distally with at least 1 claw and 2 setae.</p>
            <p>Mxl (Figs 3G, U, V, 5E, F) Protopod with branchial plate with at least 15 marginal setae. Three masticatory lobes (endites 1-3) with distal claws/setae. Palp with two segments, both with at least 3 setae on their apical margins.</p>
            <p>L5 Male (Figs 3H, I, 5D) no setae on protopod confirmed. Branchial plate with six marginal setae. Palp (endopod) a jointed clasping organ, carrying a long claw/finger-like process distally, and a shorter (sensory?) process more ventrally. Masticatory process with three or more setae. Female L5 badly preserved (Fig. 3W, X).</p>
            <p>L6 (Figs 3J, Y, Z, 5G) Walking leg with 5 segments. Segment 1 with setae d1 and d2. Segment 2 elongate with no seta preserved. Segments 3 and 4 separate, not fused. Segment 3 with seta f distally, segment 4 with no seta g observed. Segment 5 with long claw h2.</p>
            <p> L7 (Figs 3AA, AB, 5H, I) Distal parts of this appendage not preserved. Bending of this appendage dorsally suggests it being used as a typical cleaning leg. Segment 1 (basis) with setae d1, d2 and dp present. Segment 2 (first endopodal segment) long, with no seta preserved. Segment 3 preserved in one of the  male’s L7, however, only partially. </p>
            <p>Ur ramus (Figs 3K, AC, 5J) Elongate, only slightly bent, with two relatively long terminal claws of similar length preserved (approx. half the length of the posterior edge of the ramus). Posterior and anterior setae not observed.</p>
            <p>HP (Figs 4D, E, 6A, B) nearly rectangular in lateral view, with outer distal lobe wider and shorter than inner lobe. Several loops of sperm duct preserved in HP (Fig. 4E).</p>
            <p>Female genital lobes (Fig. 4F) formed as spindle-shaped projections towards posterior and extending nearly to the posterior-most end of the soft body (i.e. basis of the UR). Inside the female BA19005-2, several eggs and stored spermatozoa are preserved (Fig. 4G).</p>
            <p>Zenker Organs (Figs 3L, M, 4B, 6D) preserved in male BA19005-1 with five whorls of spines, one with the efferent part of the vas deferens attached. Vasa deferentia forming narrow U-shaped loops mid-laterally (Figs 3N, 4C).</p>
            <p>Remarks.</p>
            <p> In the original description, it was stated that this species (and genus) belongs to the  Candonidae because of the morphology of the Zenker Organ. Further, it was assigned to the  Paracypridinae and tentatively to the tribe  Renaudcypridini (Wang et al. 2020b) based on the presence of an internal antero-ventral tooth in LV and a corresponding socket in RV. This character has been defined as tribe-specific by Wouters (2001), while in the other tribes of the  Paracypridinae the sockets are missing. As specified in the present analysis, the two postero-ventral teeth in LV of  M. hui also possess corresponding sockets, albeit less pronounced than the anterior one. The other diagnostic features of the  Renaudcypridini on L7 cannot be verified with the investigated specimens, namely the strong, spiny processes situated dorso-distally on each of the segments 3 and 4 and the arrow-shaped setules on the d2 seta. Nevertheless, we here assign this genus to the  Renaudcypridini on the basis of the teeth/socket-characters of the valves, hoping that future findings of this species will offer more morphological characters to eventually verify, or falsify, this decision. </p>
            <p> Although there is clearly some affinity with the genus  Renaudcypris McKenzie, 1980,  Myanmarcypris is easily distinguished by its dorsal hump, its strong and exceptional surface ornamentation and the striking antero-lateral nodes of the valves. Some living species of the cypridid subfamily  Cypricercinae share carapace morphological characteristics with  M. hui , notably the dorsal hump and the anterior tubercles. For example,  Strandesia martensi Savatenalinton, 2015 from Thailand has a dorsal hump situated in front of mid-length, but in contrast to  M. hui its RV overlaps the LV dorsally and it lacks internal ventral marginal teeth and sockets (Savatenalinton 2015). The genus  Sataracypris Deb, 1983 from India also has a similar dorsal hump and has been tentatively assigned to the  Cypricercinae pending redescription (Savatenalinton 2015).  Bradleytriebella tuberculata (Hartmann, 1964) from Thailand has a prominent external tubercle close to the anterior margin of each valve, in a similar position to the node on each valve of  M. hui , but it has no dorsal hump or internal ventral marginal teeth and sockets (Savatenalinton and Martens 2009a). Soft parts of  M. hui are broadly similar to those of  Cypricercinae , but the morphology of the caudal ramus attachment, which in  Cypricercinae features a diagnostic  Triebel’s loop, remains unknown for  Myanmarcypris and  Sataracypris . For now, therefore, we consider the carapace similarities of  M. hui with cypricercine species to be examples of homeomorphy rather than close phylogenetic affinity. </p>
            <p> Several juvenile specimens were embedded in the same amber piece (Wang et al. 2020b), allowing for the presentation of an ontogenetic series from A-4 to A-2 (Fig. 1K-Y), including soft parts (Fig. 7, Suppl. material 3: Movie S1, Suppl. material 4: Movie S2, Suppl. material 5: Movie S3) (no A-1 specimen found). These juveniles lack the pair of antero-lateral nodes present in the  adults’ valves. The A-4 specimen even lacks the pronounced surface ornamentations of older stages (Fig. 1U). </p>

            <p>Material.</p>
            <p>Single male specimen; BA19005-8.</p>
            <p>Dimensions.</p>
            <p> L = 245  μm , H = 116  μm , W ≈ 120  μm . </p>
            <p>Description.</p>
            <p> Carapace (Figs 14A-E, 16A, C) small subtriangular shape in lateral view. Greatest height at  ¼ of length. Anterior margin broadly rounded. Posterior margin narrowly rounded. Dorsal margin straight, moderately sloping down from the greatest height to the posterior margin. Ventral margin straight in middle part in both valves, with slightly concave regions in the very middle, forming distinct flaps as an area of valve overlap (LV&gt;RV) (Fig. 16A). From posterior third, ventral margin ascending towards posterior end. Carapace in dorsal view elliptical, with posterior and anterior part compressed and central region strongly protruding. The  valve’s lateral surface punctate in the flat anterior and posterior marginal regions, while pitted (i.e., covered with wider and deeper depressions) in the central region and dorsally. Valves thick in cross section (Fig. 16C). Inflated central region with distinct sulcus mid-dorsally. Inner calcified lamella wide. Central muscular scar pattern, pore morphology and detailed hinge elements not preserved. </p>
            <p>Soft parts almost all preserved, but with a low degree of detail.</p>
            <p>A1 (Figs 14F, G, 15A, 16D) rod-shaped. Segmentation and setation not preserved.</p>
            <p>A2 (Figs 14H, I, 15B, 16D) more robust than A1, number of segments unknown. With prominent knee between protopodite and endopodite, close to which the spinneret seta (exopodite) originates, the only preserved setation of both A2 in this specimen.</p>
            <p>Between the right A2 and the internal side of RV, a roundish, disk-shaped body is preserved, which we tentatively interpret as the sac of the spinneret gland containing the secretion (Fig. 16D).</p>
            <p> Md (Figs 14J, K, 15E, 16B, E) Masticatory process of coxa preserved, reaching into the oral opening, but teeth only weakly preserved. The  palp’s segmentation and setation not preserved. Vibratory plate not preserved. </p>
            <p>Mxl (Figs 14L, M, 15C, 16B) Protopod with three masticatory lobes (endites 1-3) and two-segmented palp, without any claws/setae preserved; branchial plate preserved.</p>
            <p>L5 (Figs 14N, O, 15F, 16F) Walking leg, elongate, with long endopodite consisting of indeterminate number of segments.</p>
            <p>L6 (Figs 14P, Q, 15G, 16F) Presumed walking leg, protopodite elongate, endopod not well preserved.</p>
            <p>L7 (Figs 14R, 15H) Walking leg, elongate protopodite and long endopodite, the latter with at least three segments.</p>
            <p>HP (Figs 15D, 16F, G) almost triangular in shape, apically forming distinct tip, shaped like an arrowhead.</p>
            <p>Remarks.</p>
            <p> We assign the studied specimen to the genus  Sanyuania within the  Loxoconchidae , mainly based on shape, ornamentation and morphology of its carapace. Preserved soft parts, although with little detail, and without genus-specific features being observable, at least do not oppose this assignment. The morphology of the preserved hemipenes is clearly in line with  Hartmann’s (1966: 758) description of hemipenes typical of  Loxoconchinae as consisting of a voluminous capsule and a triangular, distally rounded top piece. A direct comparison of our  specimens’ hemipenis with that of  Sanyuania segersi Savatenalinton &amp; Martens, 2009a shows a high degree of similarity (Savatenalinton and Martens 2009a: fig. 5A) with its triangular (arrow-head-like) distal tip on a broad, rounded main body. Regarding the shape of the carapace, as well as the flattened anterior and posterior margins, our specimen is most similar to  S. cuneata Zhao &amp; Whatley, 1992. However, the surface ornamentation of the valves with broader pits centrally and smaller ones marginally, comes closer to that of  S. wangi Zhao &amp; Whatley, 1992. None of the known  Sanyuania species, however, possess the mid-dorsal sulcus featured in our specimen. Clearly our data on this single specimen are too limited for more certainty; more specimens are needed for a full taxonomic assessment. We therefore present this specimen in open nomenclature here. </p>
