8A1D87FBFFB8FFE4FF4BFD4641F0FC93.taxon	description	Generic description: Body length 7 – 11 mm. Colour: Frontal vitta uniformly dull orange. Orbital plate orange pruinose, barely differentiated from frontal vitta; epicephalon shiny orange, ocellar plate small and black. Palpus black with a contrasting white ventral margin. Thorax usually mostly orange (but see A. camelina). Fore tarsomeres white but tarsomere 5 and sometimes tarsomere 4 slightly darkened. Hind femur pale brown, in most species with a distinct preapical pale band (band absent in A. camelina). Wing mostly clear or with a broad but weak discal band. Abdominal pleuron usually with a characteristic area of dark pigmentation; male with a distinct dark pleural sac on P 2 or P 1 – 2. Head: Arista pubescent, longest hairs no more than 1 / 4 of scape width. Pedicel with one or more long ventroapical bristles, usually subequal to first flagellomere. Frontal vitta parallel sided behind ocelli, slightly broadened before ocelli, variably tapered anteriorly. Clypeus shining, usually entirely bare (microsetulose in A. tricincta n. sp.). Palpus broad but strongly tapered apically. Three similarly well-developed fronto-orbital bristles; inner vertical, outer vertical and postocellar bristles present and strong. Thorax: One or two dorsocentral bristles. Suprahumeral bristles small and exclinate, usually 3 – 5 with anterior largest, sometimes absent. Wing with long inclinate dorsal costagial bristle and somewhat shorter ventral costagials. Female abdomen: Major (paired) spermathecal duct long and distally swollen with a truncate apex from which the stout, twisted or sinuate spermathecal stems arise; paired spermathecae large, distally expanded with apex normally invaginated. Minor (single) duct greatly reduced or vestigial, single spermatheca small. Male abdomen: Epandrium and distiphallus long, basal distiphallus longer than epandrium; phallic bulb usually indistinct, distal distiphallus long and (in species other than A. affinis) with a conspicuous, sometimes spinulose, apical swelling (" glans ").	en	Marshall, Stephen A.

8A1D87FBFFB8FFE4FF4BFD4641F0FC93.taxon	etymology	Etymology: A number of widely separated clades traditionally treated as part of Grallipeza have been informally organized for several years using manuscript names with the suffix " peza ". Two of those clades are formally named using this suffix here, with the prefix " Ama " applied to this group of orange species with the type species Amapeza amazonica.	en	Marshall, Stephen A.

8A1D87FBFFB8FFE4FF4BFD4641F0FC93.taxon	discussion	Comments: The female and male genitalia of Amapeza species, especially the long distal distiphallus and greatly reduced third spermatheca, are distinct from other taxa previously treated as Grallipeza. CO 1 sequences (barcodes) for A. plicata, A. amazonica and A. camelina suggest that the species of Amapeza form a monophyletic group that is widely separated from other species previously treated as Grallipeza, and an unpublished analysis using multiple genes (12 S, three segments of the gene 28 S referred to as 28 S – 2, 28 S – 3 and 28 S – 5 and CO 1 – 3 ′) recovers the three included species of Amapeza as the sister group to Systellapha plus a large undescribed genus (Lindsay and Marshall, in manuscript). The same analyses recover Grallipeza ss as the sister group to Calosphen Hennig. Key to the species of Amapeza	en	Marshall, Stephen A.

8A1D87FBFFBDFFE0FF4BFC9245AEFE27.taxon	discussion	Comments: Amapeza amazonica is closely related to A. tricincta, with which it shares several characters including the setose abdominal pleuron, a single dorsocentral bristle, and the enlarged and capsule-like part of the paired spermathecal duct. Some previous published records of A. amazonica are probably A. hyaloptera; see comments under that species. Like A. hyaloptera and A. camelina, A. amazonica and A. tricincta have an apically swollen distal distiphallus.	en	Marshall, Stephen A.

8A1D87FBFFBFFFE0FF4BFE2E469BF83B.taxon	discussion	Comments: Although its dark body colour gives Amapeza camelina a superficial similarity to Nigripeza, it can be recognized as an Amapeza by its distinctively shaped white-fringed palpus and pubescent antenna. Both male and female genitalia are distinctive and suggest a close relationship to A. amazonica, A. hyaloptera and A. plicata. The dorsally recurved and distally swollen distiphallus apex is an unusual synapomorphy linking these four species, although a similar structure appears as an apparent homoplasy in the Afrotropical genus Aristobatina Verbeke, in which it was referred to as a " glans " (Marshall, 2014).	en	Marshall, Stephen A.

8A1D87FBFFB1FFEEFF4BFF6247B6F83E.taxon	discussion	Comments: Amapeza hyaloptera is externally similar to the closely related A. plicata, from which it can be distinguished by its smooth postpronotal lobe and by its distinctive male and female terminalia (see also comments under A. plicata). Although A. hyaloptera differs from A. amazonica in several distinctive features (including the number of dorsocentral bristles), three of the above specimens bear labels " Grallipeza amazonica Enderlein det. L. Albuquerque ". It is therefore possible that previous published records of A. amazonica from Brazil are this species. Several of the types were taken in Shannon traps or Malaise traps, and the species seems to be common in Amazonia. Although the type specimen should presumably be in NHMW, I was not able to find it in 2002 when I made notes on the Micropezidae types there. The original description, however, leaves little doubt about the identity of this species, especially in the explicit mention of two dorsocentral bristles.	en	Marshall, Stephen A.

8A1D87FBFFB3FFEDFF4BFF62465DF983.taxon	etymology	Etymology: The species name refers to the fold-like swelling on the posterior part of the postnotum (Latin plicatus = folded), a prominent feature of at least the females of this species.	en	Marshall, Stephen A.

8A1D87FBFFB3FFEDFF4BFF62465DF983.taxon	discussion	Comments: Amapeza plicata and Amapeza hyaloptera are closely related and externally similar except for the setose elevation on the posterior part of the postnotum, which is weakly developed on the two A. plicata males examined. The spermathecae and spermathecal ducts of these species are clearly distinct yet share several features such as the very broad, distally truncate, at least partly thin-walled main duct and narrow, funnel-shaped paired spermathecae. The two available males of A. plicata also have unusual features shared with A. hyaloptera and A. camelina, especially the recurved distal distiphallus that ends in large spinulose bulb in A. hyaloptera but only forms an indistinct expansion in A. plicata.	en	Marshall, Stephen A.

Male abdominal pleuron darkened by dense short setulosity, darkest on dorsal third of P 2. Head: Frontal vitta slightly broadened before ocelli, then strongly tapered anteriorly with anterior margin 0.2 X frontal width. Orbital plate barely differentiated from frontal vitta; epicephalon shiny. Clypeus entirely and conspicuously setulose. Thorax: Cervical sclerite evenly convex and simple in male, with a central depression in female. Proepisternum with a row of short ventral setulae anteriorly, posterior corner with a single very long bristle widely separated from short anterior setulae. Postpronotal lobe of male almost bare, with a few inconspicuous golden posterodorsal setulae; postpronotal lobe of female with thin but long black dorsal bristles anteriorly and posteriorly, the posterior group of bristles denser and longer. One dorsocentral bristle. Mesopleuron shining, anepisternum sparsely setulose. Suprahumeral bristles small and exclinate, usually 3 – 5 with anterior largest. Female abdomen: Major (paired) spermathecal duct extremely broad, distally expanded and cup-like, with thick, distally bumpy and bent spermathecal stems running from inside the cup to long, distally invaginated paired spermathecae. Single spermathecal duct very thin and short, leading to a long, slender and very small single spermatheca. Male abdomen: Genital fork prominent, with long, narrow, incurved arms, deeply cleft basally but without inner basal processes, inner faces of arms with only short stout setae. Basal distiphallus elongate, about 1.5 X as long as epandrium, with an elongate phallic bulb.

8A1D87FBFFB2FFEBFF4BF98A40D1FB47.taxon	discussion	Comments: Amapeza tricincta can be easily separated from the otherwise similar A. amazonica by its entirely microsetulose clypeus, which contrasts unambiguously with the shining clypeus of A. amazonica, as well as by leg colour and katepisternal bristle colour. Amapeza tricincta is thus far known only from the lower Amazon region of Brazil, while A. amazonica is known from upper Amazon regions of Brazil, Ecuador and Peru.	en	Marshall, Stephen A.

8A1D87FBFFB4FFE8FF4BFACE41F0F9C1.taxon	discussion	Comments: Hennig (1934) included three black-bodied species in his key to Grallipeza species. Only one of these species (Grallipeza obscura Hennig) belongs in Nigripeza; the others (Grallipeza auriornata Hennig and Calobata pallidefasciata Macquart) are dark-bodied species with a bare or indistinctly pubescent arista, and probably belong in Calosphen. Three specimens of Nigripeza (two N. obscura, one N. octa) were sequenced for CO 1 and recovered together as an isolated branch widely separated from the Grallipeza ss / Calosphen clade on maximum likelihood trees including over 100 taeniapterine species (unpublished data).	en	Marshall, Stephen A.

8A1D87FBFFABFFF5FF4BFF6246F7FB9B.taxon	etymology	Etymology: The name Nigripeza octa was applied to this species because it has long carried the manuscript name " species 8 ".	en	Marshall, Stephen A. (2022): Amapeza and Nigripeza, new genera of Neotropical micropezid flies (Diptera, Micropezidae, Taeniapterinae). Zootaxa 5092 (3): 251-272, DOI: 10.11646/zootaxa.5092.3.1
8A1D87FBFFABFFF5FF4BFF6246F7FB9B.taxon	discussion	Comments: Nigripeza octa is the only Central American species in this otherwise South American genus. The holotype shows unusual apparent asymmetry in the number of dorsocentral bristles, a character that is usually stable and symmetrical. A specimen of this species (labelled TAE 089) was treated under the manuscript name Grallipeza " octa " in Jackson et al 2015. It was the only species of Nigripeza or Amapeza included in that paper, in which the Majority Rule Consensus cladogram recovered it as sister to a clade including Hoplocheiloma Cresson and the one species of Grallipeza ss included in the paper.	en	Marshall, Stephen A.

8A1D87FBFFAAFFF2FF4BFB744007FE7E.taxon	description	Figures 10 A – 10 D Description: Colour: Body mostly black, head dark brown dorsally, frontal vitta orange anteriorly but phasing to brown posteriorly. Orbital plate pruinose orange, epicephalon dark shiny brown, ocellar plate small and black. Clypeus dark brown. Fore femur brown basally, yellow distally. Fore tibia dark brown, fore tarsomeres 1 – 2 white, 3 – 5 black. Other legs yellowish brown; hind femur with a strong and elongate dark ring in basal third; distomedian and distal rings very faint. Vertical row of katepisternal bristles black. Wing with complete but weak broad discal band. Abdominal pleuron (discoloured on available specimens) apparently dirty white except for the male pleural sac, which is large, brownish with dense black microsetulosity. Female oviscape pruinose basally but otherwise shining dark brown, apex pale. Head: Frontal vitta almost parallel sided behind ocelli, expanded and slightly elevated in front of ocelli, hardly tapered anteriorly. Orbital plate dulled with very fine striae; epicephalon shiny and bare; paracephalon mostly bare, microsetulose only between postocellar and inner vertical bristles. Clypeus entirely microsetulose. Thorax: Postpronotal lobe distinctly elevated posteriorly, sparsely microsetulose. One dorsocentral bristle. Suprahumeral bristles absent. Female abdomen: Major (paired) spermathecal duct elongate and almost parallel-sided, gradually expanded to a bulb-like swollen apex from which short, distally expanded transversely striate, convoluted stems lead to 2 funnel-shaped spermathecae. Spermathecae with distinct outpocketings at base and broad distal invaginations. Minor (single) duct shorter and slightly narrower but similar in shape, single spermatheca large, similar to paired spermathecae. Male abdomen: Genital fork with very short, broad, parallel-sided and straight arms; 5 short stout bristles on mesal surface, all in apical third, and 3 long outer preapical or apical bristles as long as or longer than length of arm. Distiphallus short and broad, ending in a broad but tapered and distally pointed phallic bulb. Ejaculatory apodeme not clearly visible in only available male, but apparently smaller than epandrium.	en	Marshall, Stephen A.

8A1D87FBFFAAFFF2FF4BFB744007FE7E.taxon	etymology	Etymology: Nigripeza spangleri is named after coleopterist Paul Spangler, the collector of this and many other new insect species.	en	Marshall, Stephen A. (2022): Amapeza and Nigripeza, new genera of Neotropical micropezid flies (Diptera, Micropezidae, Taeniapterinae). Zootaxa 5092 (3): 251-272, DOI: 10.11646/zootaxa.5092.3.1
8A1D87FBFFAAFFF2FF4BFB744007FE7E.taxon	discussion	Comments: Nigripeza spangleri is very similar to the closely related N. obscura, the only dark congener with a plumose arista. Both species have a swollen cervical sclerite and a single dorsocentral bristle. Male and female terminalia of these species reflect the close relationship but differ clearly in details such as the shape, dimensions and chaetotaxy of the genital fork and the shape and dimensions of the spermathecae and associated ducts. Nigripeza spangleri is distinctive for its very short genital fork and very large single spermatheca.	en	Marshall, Stephen A.
