Males of C. ismayi are distinguished from the other known Australasian species of the genus by their elongate yellow palpus (Fig. 12), grey body, yellow legs and several hypopygial features (Shamshev &amp; Grootaert 2002, figs 18–22) including: left ventral epandrial process with tip weakly bent; left ventral surstylus relatively short with short setae; right ventral epandrial process straight; phallus with funnel-like tip; hypoproct simple and narrow. Females of C. ismayi (see “Remarks” below) are distinguished by the following features: fore femur with row of 4–5 long spine-like ventral setae on basal half (Fig. 13); palpus elongate and brownish with 3 long spine-like ventral setae (about 2X palpus width); terminalia with syntergite 9+10 undivided and bearing acanthophorous setae, cercus narrowly rounded apically with prominent preapical seta (Shamshev &amp; Grootaert 2002, figs 23–25).</p> <p>Distribution. Chimerothalassius ismayi is known only from New Zealand and has been collected at Ôwhiro Bay and Stony Bay on North Island, and Cable Bay, Port Levy and South Birdlings Flat [ca 43°49ʹS 172°42ʹE] on the northern part of South Island (Figs 3–7).</p> <p>Remarks. The type series from South Birdlings Flat and the female specimens from Ôwhiro Bay and Stony Bay were swept or hand collected from stony beaches (e.g., Fig. 4) or beaches with mixed pebbles and sand, while the Port Levy male specimen was taken in a pan trap along a stream bed near the sea (Fig. 6). Shamshev &amp; Grootaert (2002) noted great sexual dimorphism in the chaetotaxy of the palpus and foreleg of C. ismayi, which is not seen in C. runyoni Brooks &amp; Cumming from the Caribbean (Brooks &amp; Cumming 2018), or C. riparius sp. nov. from New Caledonia, described below. Although we have not seen the type series of C. ismayi (8 males and 14 females from South Birdlings Flat, South Island deposited in the Royal Belgian Institute of Natural Sciences, Brussels, Belgium), we have examined a male collected from the nearby locality of Port Levy (DEBU), and females collected from Cable Bay (USNM), Ôwhiro Bay and Stony Bay (NZAC) that are virtually identical to the male holotype, male paratypes and female paratypes illustrated and described by Shamshev &amp; Grootaert (2002, figs 1–26). Given the major differences in the chaetotaxy of the palpus and foreleg between the males and females of the type series (as well as the male and females we examined), we suspect that the female paratypes of C. ismayi and the females from Cable Bay, Ôwhiro Bay and Stony Bay actually belong to an undescribed species for which the male remains undiscovered. Even though the type specimens of C. ismayi were all collected from a single stony beach on the same day, multiple species of certain parathalassiine shoreline genera, such as Amphithalassius Ulrich, Parathalassius Mik, and Plesiothalassius Ulrich are known to co-inhabit single beaches (Ulrich 1991; Brooks &amp; Cumming 2017). The same appears true for Chimerothalassius, at least at the Port Levy locality, where both C. ismayi and C. marshalli sp. nov. were taken during the same collecting event. The female specimens currently assigned to C. ismayi also do not appear to be conspecific with C. marshalli sp. nov. based on differences in chaetotaxy of the palpus, gena, thorax and foreleg.</p> </div>	https://treatment.plazi.org/id/038D87B8C813200DEBC3E61A9E24A9C2	Public Domain	No known copyright restrictions apply.

Species of Chimerothalassius are known from the Caribbean, Costa Rica, New Zealand (Figs 3–7) (Brooks &amp; Cumming 2018) and now New Caledonia (Figs 8–10) (Cumming &amp; Brooks 2019, as “Undescribed genus [New Caledonia]”). The genus is found on rocky, stony or sandy habitats of coastal beaches (Figs 4–7) and emerged rocks in rivers (Figs 9, 10) (Shamshev &amp; Grootaert 2002; Brooks &amp; Cumming 2018; Cumming &amp; Brooks 2019).</p> </div>	https://treatment.plazi.org/id/038D87B8C813200AEBC3E2A29FA8AF13	Public Domain	No known copyright restrictions apply.

The specific epithet refers to the riparian habit of the new species (Figs 9, 10).</p> <p>Remarks. Formerly, Cumming &amp; Brooks (2019) included this exemplar species (i.e., “ New Caledonia sp.”) as a member of “Undescribed genus [New Caledonia]” in their phylogenetic analysis of the Parathalassiinae, because presence of female terminalia with acanthophorous spines was not considered typical of Chimerothalassius at that time. The type series of C. riparius sp. nov. was collected together with the holotype of C. sinclairi sp. nov. in yellow pan traps placed along the margin of Rivère Bleue.</p> </div>	https://treatment.plazi.org/id/038D87B8C8172000EBC3E2EA9C4AA953	Public Domain	No known copyright restrictions apply.

While sorting a loan of NZAC Empidoidea in the early 1990s, Brad Sinclair (pers. comm., 2022) noted examining a single female parathalassiine specimen, with wing cell dm absent, from the Three Kings Islands (Manawatâwhi). The specimen, provisionally determined as Microphorella, was returned in 1995, but could not be located in the Diptera holdings of the NZAC (D. Ward, pers. comm., 2022). Although examination of the specimen will be required for precise identification, we strongly suspect it belongs to Chimerothalassius, in which case it would represent the most northerly record of the genus in New Zealand (Fig. 3).</p> </div>	https://treatment.plazi.org/id/038D87B8C81D2004EBC3E2EA9B51A92A	Public Domain	No known copyright restrictions apply.

The genus Eothalassius is distinguished from other parathalassiine genera by the following characters: head with face narrow (less than or about width of anterior ocellus, Fig. 35), gena scarcely projected below eye, antenna with arista-like stylus lengthened (at least 5X length of postpedicel, Fig. 35), mouthparts directed ventrally with fleshy labellum, palpus broad and flattened (particularly in males) with apex slightly pointed to widely rounded apically (Fig. 35); thorax with prosternum fused to proepisternum forming precoxal bridge, scutellum with 1 pair of strong setae near apex; wing with R 1 short reaching costa before middle of wing (or before base of M 2), crossvein bm-m incomplete, cell dm present (Fig. 36) or if absent without vein dm-m, CuA rounded, cell cua convex apically, anal lobe not developed; male terminalia with right epandrial lamella lacking ventral process, hypoproct projected as pair of non-setose asymmetrical lobes, cerci broad and asymmetrical; female abdomen with apical segments retracted into segment 6 (Fig. 34), terminalia (Figs 37, 38) with syntergite 9+10 divided and bearing acanthophorous setae, cercus slender and terminating with long seta.</p> <p>Remarks. Species of Eothalassius are known from the Mediterranean coast of Turkey, Cyprus and Malta (E. merzi (Gatt)), the Pacific coast of Costa Rica (E. borkenti Cumming &amp; Brooks), the coasts of Southeast Asia and Papua New Guinea (E. gracilis Shamshev &amp; Grootaert and E. platypalpus Shamshev &amp; Grootaert) and now the coast of New Caledonia (Eothalassius sp.) (Cumming &amp; Brooks 2019). Shamshev &amp; Grootaert (2005) indicate that the type series of Eothalassius gracilis was collected from littoral and supralittoral zones of sandy coastal beaches, and E. platypalpus was collected along creeks exiting onto sandy coastal beaches. Eothalassius merzi was also collected on sandy coastal beaches (Gatt 2003), whereas E. borkenti was found on rocky seashores (Brooks &amp; Cumming 2011).</p> </div>	https://treatment.plazi.org/id/038D87B8C81D2004EBC3E0169E57AE84	Public Domain	No known copyright restrictions apply.

Australasian Microphorella can be distinguished from other parathalassiines by the following suite of characters: head with face broad (about width of combined antennal bases or wider) (Fig. 41), gena weakly developed to moderately broad, antenna with arista-like stylus not lengthened (about 2X length of postpedicel) (Figs 40, 51), mouthparts directed ventrally with fleshy labellum, palpus narrowly ovate (Figs 40, 41, 51), or broadly clavate and flattened; thorax with prosternum fused to proepisternum forming precoxal bridge, scutellum with 1 pair of strong setae near apex; wing with vein M 2 and cell dm present (Fig. 52), vein R 1 reaching costa beyond or (rarely) just before base of M 2, cell cua convex apically, vein CuA + CuP short to absent, anal lobe barely developed; male terminalia with right epandrial lamella lacking ventral process, cerci including hypoproct nearly symmetrical and pointed (Figs 44–46, 48); female abdomen with apical segments retracted into segment 6, syntergite 9+10 divided and bearing acanthophorous setae or acanthophorous spines, cercus narrowly rounded or pointed apically with or without apical setae.</p> <p>Remarks. Microphorella as currently recognized, is made up of at least 12 species groups worldwide (Cumming &amp; Brooks 2019, 2022). Three of these species groups are known from the Australasian Region and are not closely related (Cumming &amp; Brooks 2019). The three separate groups comprise the M. malaysiana species group with three Southeast Asian species plus M. papuana Shamshev &amp; Grootaert from Irian Jaya, New Guinea (Shamshev &amp; Grootaert 2004), the M. iota species group, with a single species from eastern Australia, and a separate Australian species group that includes two new species described below. Worldwide the genus is known from various riparian and coastal habitats (Cumming &amp; Brooks 2019), with the New Guinean M. papuana restricted to coastal beaches and the Australian species collected along creeks and streams.</p> </div>	https://treatment.plazi.org/id/038D87B8C81E2006EBC3E4C99CE6A9B6	Public Domain	No known copyright restrictions apply.

Phallus tubular, J-shaped, projected dorsally, not extending beyond upper margin of postgonite, tip straight and unmodified. Ejaculatory apodeme keel-like. Hypoproct simple, short with rounded margin, left and right sides slightly asymmetrical. Cercus somewhat broad and globular laterally with short pointed apicolateral process, with several setae medially, left and right cercus asymmetrical.</p> <p>Female. Unknown.</p> <p>Distribution. This species is known only from the type locality of Buckley’s Creek in Warrumbungle National Park, New South Wales, Australia (Fig. 1).</p> <p>Etymology. The species name is derived from Warrumbungle after the type locality in Warrumbungle National Park and should be regarded as a noun in apposition.</p> <p>Remarks. This species was collected along Buckley’s Creek. Aside from the difference in phallic structure, the hypopygial morphology of M. bungle sp. nov. is very similar to M. viticula sp. nov. and the species appear closely related.</p> </div>	https://treatment.plazi.org/id/038D87B8C81F201BEBC3E0AB9FA3AABA	Public Domain	No known copyright restrictions apply.

Males of M. iota are distinguished from the other known Australasian Microphorella by the following combination of features: body and legs blackish brown or blackish grey with black setation; palpus dark and narrowly ovate, dorsal surface with club-tipped processes (Colless 1964, fig. 1d); hypopygium (Figs 47, 48) with phallus relatively short, swollen along midlength, with tip bent back and brush-like; hypandrium large, distinctly wider than epandrial lamellae in lateral view.</p> <p>Distribution. In addition to the two localities in the Australian Capital Territory listed above, Colless (1964) recorded two female paratypes (in the Australian Museum, Sydney, Australia) from Sassafras Gully [ca 33.6992°S 150.5711°E], Springwood, in the Blue Mountains of New South Wales collected by D.K. McAlpine on 10.i.1956. We have also seen additional specimens from Colo Vale in New South Wales (Fig. 1).</p> <p>Remarks. Until this study, M. iota was the the only described species of Microphorella known from Australia. In their phylogenetic analysis of the Parathalassiinae, Cumming &amp; Brooks (2019), determined that M. iota was not closely related to M. papuana from New Guinea or the two new Australian species of Microphorella described in this paper. Males of M. iota have club-tipped processes on the dorsal surface of the palpus, possess a unique phallus with a modified brush-like apex and have a large hypandrium. Colless (1964) states that specimens of M. iota were all collected by sweeping near streams. The females from Colo Vale differ slightly from the other known specimens by their blackish grey coloration.</p> </div>	https://treatment.plazi.org/id/038D87B8C802201DEBC3E3A79D43A92B	Public Domain	No known copyright restrictions apply.

Sinclair / ex. dry scler. creek”; “ HOLOTYPE / Microphorella viticula / Brooks &amp; Cumming [red label]” (CNC).</p> <p>Diagnosis. Males of M. viticula sp. nov. are distinguished from the other known Australasian Microphorella by the following combination of features: body and legs dark brown with black setation (Fig. 49); palpus dark and narrowly ovate (Fig. 51); hypopygium (Figs 53–55) with phallus greatly elongated, slender and tightly curled; hypandrium relatively small, slightly wider than epandrial lamellae in lateral view.</p> <p>Description. Male (Fig. 49): Body length 1.32 mm, wing length 1.35 mm. Similar to M. bungle sp. nov. except as follows: Head (Figs 50, 51): 2 pairs of inclinate fronto-orbitals, posterior pair smaller; postocular setae slightly longer and pale brown; postpedicel 2X longer than wide, with basal half round and distal half narrow; arista-like stylus 1.8X length of postpedicel. Thorax (Fig. 50). Legs (Fig. 49). Wing (Fig. 52). Abdomen (Figs 49, 53–55): Hypopygium (some details not visible on unique undissected holotype): Left ventral epandrial process longer. Ventral lobe of right surstylus apparently short, with a few apical setae. Hypandrium with posterior margin drawn into short pointed tip projecting dorsally and supporting protruding phallus. Ventral part of left postgonite lobe (medial to base of left ventral epandrial process) apparently developed into large flap-like lobe. Phallus greatly elongated, slender and tightly curled.</p> <p>Female. Unknown.</p> <p>Distribution. This species is known only from the type locality of Govetts Leap in Blue Mountains National Park, New South Wales, Australia (Figs 1, 2).</p> <p>Etymology. From the Latin viticula, meaning tendril, in reference to the long thin curled phallus of the male.</p> <p>Remarks. The single holotype male is stated as having been taken in dry sclerophyl habitat near the creek (Fig. 2), but was likely collected where the trail crosses the stream (B.J. Sinclair, pers. comm., 2022). Aside from the difference in phallic structure, the hypopygial morphology of M. viticula sp. nov. is very similar to M. bungle sp. nov. and the species appear closely related.</p> </div>	https://treatment.plazi.org/id/038D87B8C804201DEBC3E0179D0CAD63	Public Domain	No known copyright restrictions apply.
