Day, 1cS, 1縠 (AM). This is the " imperialis Cooktownform " ofPart 1, closely resembling A. imperialis, but differing as follows: Male. Head: frons relatively short (Table 2, "Cooktown form"); antennal segment ratio 3.1-3.8. Carina slightly, but distinctly, flatter in profile, less protruding, and therefore less clearly separated from epistome. Wing: bend ofM relatively closer to wing margin, index 0.6-0.9; upper calypter more than 50% dark, the external margin and associated fringe continuing brown or golden-brown to junction with lower member. Legs: hind tibia (Fig. 24) with conspicuous ad fringe of close-set bristles of more or less uniform length and strength, about as long as the tibia is wide. Abdomen: T 3 lacking the usual pair of median marginal bristles. T 3 with lateral pale patches reduced, sometimes absent. Genital segments lacking the strong, almost spiny bristles present in othermembers of the group. Female. Differing from imperialis in the M-bend index and calypter colouration; also, lateral pale patches on abdominal T 3 usually absent; antennal segment ratio 2.7-3.2. Notes. The species was first recognised morphometrically in the male sex only (see Part 1, Fig. 7). Additional diagnostic attributes were later discovered, including the colouration of the calypters, which enabled identification of females. The list of specimens examined includes a number identified since the morphometric studies were made. Distribution (Fig. 3). North Queensland.Published as part of Colless, D.

AUSTRALIA: New South Wales, Colo Vale [ca 34.4017°S 150.4886°E], 17.i.1957, W.W, Wirth (5♀, USNM). Diagnosis. 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. 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). 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 & 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.Published as part of Brooks, Scott E. & Cumming, Jeffrey M., 2022, New Australasian Parathalassiinae (Diptera: Dolichopodidae sensu lato), pp. 521-543 in Zootaxa 5188 (6) on pages 539-541, DOI: 10.11646/zootaxa.5188.6.2, http://zenodo.org/record/710361
Stilbomyella anomala Colless 1998, n.sp.
No full textStilbomyella anomala n.sp. Holotype: female; Palmerston NP, 1200 ft, Queensland, 18 April 1971, D.A. Duckhouse, (light trap). Ex spirit via ethyl acetate. ANIC No. 6143. The type locality is near the Palmerston Highway, between Innisfail and Millaa Millaa, north Queensland. A small dark species, body length 7.0 mm. Female. Head. Interfrons dark brown; parafrontals, parafacials, genae, and postorbits golden pollinose; hairs of genae pale golden. In facial view inner surface of facial ridge dark, continuing as a black line through vibrissa and ventrally along subcranial margin. Frons relatively narrow, 0.2 of head width. Vertical bristles strong, inner verticals decussate, parafrontal with 2 strong proclinate frontoorbitals and 1 exclinate (prevertical); ocellar bristles not differentiated. Carina in lateral view quite strongly protruding, curved; in facial view, more or less parallelsided on ventral two-thirds, tapering dorsally; separated from epistome by a distinct but rounded notch. Antenna completely dark; segment 3 a little shorter than carina and than arista. Palps dark. Gena 0.4 of eye height. Thorax. Scutum and scutellum metallic green, the former (in glancing light) with trace of silvery frosting on humeri and notopleura, and (in some lights) an ill-defined median dark vitta. Scutellum with preapical bristles rather erect (but not "spiny", as typical of Silbomyia). Pleura metallic green with large silver-pollinose area over anepisternite and stemopleuron. Propleuron bare. Legs. Fore tibia with 1 pv, no pd. Mid femur with usual group of 3 strong a bristles near centre; mid tibia with 2 strong ad and 1 pv. Hind coxa bare on posterodorsal surface. Wing. Costa setulose ventrally between Sc and RI' as in Silbomyia, but not apical to RI' Membrane strongly infuscated anterobasally, as far back as R 4+s, and along M2 and M4. M-bend index 0.7. Lower calypter dark on apical half. Abdomen. T 1+2 dark, other tergites metallic green with apical dark bands in some lights; T 3 and T 5 with lateral silver-pollinose spots ventrally. T 3 with single strong median bristle (presumably an aberration). Stemites dark, with sparse, coarse bristles. Male unknown. Notes. Despite the setulose ventral surface of the costa (a "key-character" for Silbomyia), anomala seems best accommodated in Stilbomyella by virtue of the attributes given in the key, especially the unusual lack of differentiated ocellar bristles. As shown in Part 3 (Figs 18-22), it clusters closely with that genus phenetically.Published as part of Colless, D.

Chetoneura Colless
No full textChetoneura Colless Chetoneura Colless 1962: 437. Type –species, Chetoneura cavernae Colless, by original designation. Diagnosis. Adult mouthparts reduced, two ocelli, flagellum laterally compressed, mediotergite weakly sclerotized, with a group of setae medially. Wing vein R 4 absent; wing veins dark, membrane brownish, but without maculation. Gonostyle of male club–shaped, not bifid. Female terminalia with largely developed gonapophyses 8, entirely involving the distal part of the terminalia. Larva inhabiting caves. Comments. Colless (1962) listed some features present in his new species C. cavernae as diagnostic of the genus Chetoneura. Among them are the flattened flagellomeres, the presence of only two ocelli, reduced mouthparts, presence of anepisternal setae, no postspiracular setae, laterotergite bare, regular rows of tibial setulae, and unbranched R 4 + 5. All these features are present in the species collected in Shennong Gong, herein described. The features that differ are the absence of “strong bristles dorsally” on the “metanotum”, the short fusion of M 1 + 2 with Rs, and the absence of a distal spine on the male gonostyle. However, there are additional features that suggested relationship between the two species, such as the general shape of the male terminalia, elongated anteriorly, the concentration of setae internally on the gonocoxites, the dorsal lobe of the gonocoxites, and the very unusual shape of the female sternite VIII. Even though the larval habitus of Chetoneura cavernae is not described, the fact that both species were collected in caves and other apomorphic morphological features suggest that the genus is monophyletic. Two other papers (McClure et al. 1967, Dittmar et al. 2005) have made reference to the Malaysian species of Chetoneura. In the original description, the position of the genus was not clear. Colless (1962) noted some features that are similar in Chetoneura and Keroplatus, such as the reduced palpus, but also listed a number of shared characteristics with Orfelia, and concluded that Chetoneura has a closer relationships to Orfelia than Keroplatus. This may have been the reason why Matile (1990) did not include the genus in the Keroplatini in his phylogenetic analysis of the tribe. The genus Chetoneura is herein formally transferred to the tribe Keroplatini.Published as part of Amorim, Dalton De Souza & Clarke, Arthur K, 2008, Chetoneura shennonggongensis, a new species of cave – dwelling Keroplatini from China (Diptera: Keroplatidae), with a discussion of the position of Chetoneura, pp. 59-68 in Zootaxa 1716 on page 60, DOI: 10.5281/zenodo.18100

Manota hamulata Colless
No full textManota hamulata Colless (Figs 16 A–D) Manota hamulata Colless, 1966: 656. A small-sized Manota. Male. Coloration. Pale yellowish-brown, frons, vertex and occiput darker brown, mouthparts and legs paler than other parts, wing unicolorous, knob of haltere black. Head. Antennal flagellomere 4, Fig. 16 D. Palpomere 3 of maxillary palpus with apicomesial extension, with 5 apically expanded curved sensilla; palpomere 4 with parasegment. Thorax. Pleural setosity pattern similar to M. bicuspis, Fig. 1 E: anepisternum setose, with 39–69 setae; anterior basalare non-setose; preepisternum 2 setose, with 9–27 setae; laterotergite setose, with ca. 22–30 setae; episternum 3 setose, with ca. 5–26 setae. Wing. Length 1.4 mm. Hypopygium (Figs 16 A–C). Sternite 9 extending posteriorly near to the level of the gonostylar base, sharply delimited laterally, posterior margin convex, medially acuminate, anterior margin deeply incised, the setae similar to adjacent ventral setae of gonocoxa. Parastylar lobe well exposed in ventral view, with a large lobe directed obliquely posteriorly and two lobe-like expansions at base, with one seta at the apex of the large lobe and two setae more basally on the dorsal side of that lobe, one of these two setae more anterior and one more posterior. Paraapodemal lobe exposed in ventral view, not drawn in Fig. 16 A, similar to M. parilis, Fig. 18 A. The dorsal mesial margin of gonocoxa with a large rounded setose lobe at the middle and a large broad lobe apically with a few rather strong setae on mesial margin and with two or three long setae arising from the ventral surface. Two juxtagonostylar setae present, a curved megaseta and a strong seta, both arising from a common basal body which is longer than the megaseta, the megaseta at the apex of the basal body, the seta more basal in position. Gonostylus laterally flattened, the dorsal and ventral surfaces very narrow, in lateral view the gonostylus subtriangular with a narrow basal part and a broad apical part, the apicodorsal margin very indistinctly lobed, the setae on dorsal, lateral and ventral faces similar to ventral hairs of gonocoxa, the apical margin of gonostylus with a row of setae directed mesad with the two or three most dorsal setae thicker than the others but not conspicuously so, the mesial face of gonostylus non-setose and without prominent microtrichia. Tegmen elongate-triangular, without distinct lateral shoulders. Hypoproct posteriorly extending to the level of the base of gonostylus, with ca. 20 long scattered ventral setae on each half. Cerci separate. Female and preimaginal stages unknown. Discussion. M. hamulata was described from the Caroline Islands, Palau Islands: the holotype male from Angaur Island and a paratype male each from Babelthuap Island and Malakal Island, but it has not been recorded since. I have not studied the type-material, but the excellent description by Colless (1966) leaves scarcely any doubt as to the conspecifity of my present New Guinea specimens: The hypopygium is similar and the unusually shaped and complex parastylar lobe is exactly the same in the New Guinea specimens as in Colless’ drawing. The specimens from Tekadu differ from the other specimens by having three, not two, stronger setae dorsally at the apical margin of gonostylus. They may represent a new species, but the rather poor mounts do not permit a detailed analysis to be made. M. hamulata is similar to M. bicuspis. It is distinguished as follows: 1) The parastylar lobe has two small lobes at the base of the long main part and the latter is slightly constricted at the base, but in M. bicuspis there is only one inconspicuous smaller lobe at the base of the parallel-sided main part. The shape of the parastylar lobe is somewhat sensitive to its position in the mount and the more dorsal of the two small basal lobes may be difficult to observe when the tip of the large lobe is moved in a dorsal direction from the position shown in Fig. 16 A. 2) The two or three enlarged setae mesially at the dorsal part of the apical margin of gonostylus are relatively weak, not much stronger than the unmodified setae on the same margin, and they do not arise from a distinct small lobe, but in M. bicuspis the setae are conspicuously stronger than the other setae on the margin and they arise from a distinct small lobe. 3) The row of setae at the above-mentioned margin of gonostylus is contiguous instead of being interrupted by a gap ventral of the stronger setae, and the setae are rather wide apart so that the distance between them is longer than the diameter of their sockets, unlike M. bicuspis in which the distance is only one socket wide or shorter. 4) The lobe at the middle of the dorsal mesial margin of the gonocoxa is more strongly pronounced and has more setae, ca. 20 instead of ca 10. In the present material at least, M. hamulata is smaller than M. bicuspis, wing length 1.4 as opposed to 1.8. mm. M. hamulata and M. bicuspis are similar to M. parilis. For the distinguishing characters, see under the latter.
