Manota williamsi sp. n.

Figs 1 A–C, 2A–F

Male. Colour. Head brown, face somewhat paler. Antenna light brown, including scape and pedicel. Clypeus and mouthparts yellowish. Thorax brown to dark brown, medial part of scutum and scutellum somewhat darker due to their curvature on slide. Legs yellowish, mid- and hind femora basally infuscated. Wing with brownish tinge because of microtrichia; halter mostly yellow, with blackish knob. Abdomen brown to dark brown, tergites laterally and sternites lighter. All setosity pale, yellowish or brownish, thicker setae darker than finer ones. Head. Fourth antennal flagellomere 1.0–1.2 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 curved apical sensillae; palpomere 4 with parasegment; palpomere 5 ca. 1.5 times longer than palpomere 4. Number of strong postocular setae 11. Thorax. Anepisternum with 11–17 setae; anterior basalare and laterotergite non-setose; preepisternum 2 with 11–18 setae; metepisternum with 19-28 setae. Legs. Mid tibial organ present, extending over about one third of tibial length ( Fig. 1B ). Hind tibial organ absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 extending to level of tip of R 1; wing length 1.8–2.1 mm. Hypopygium ( Figs. 1C , 2 A–F). Sternite 9 tapering, laterally free from gonocoxa, posteriorly blunt, extending to about middle between the bases of gonocoxa and gonostylus, anterior margin with deep and narrow V-shaped medial incision dividing sternite almost into two halves, anterior part non-setose, setae on posterior part similar to those on ventral side of gonocoxa. Parastylar lobe small, finger-like, with 2–3 setae apically. Paraapodemal lobe not observed. Ventral and dorsal medial margins of gonocoxa simple, both slightly bulging medially. Ventrally from dorsal medial margin of gonocoxa an anterior finger-like lobe with 5–6 apical setae and a large posterior lobe that is posteromedially drawn out, bearing ca. 30 apically curved setae. Dorsal setae on anterior half of gonocoxa similar to those on ventral side; dorsal setae on posterior half of gonocoxa somewhat longer. Two juxtagonostylar setae present, a flattened, sub-apically geniculate megaseta, with a sub-apical medially directed whip-like branch and a weak and shorter normal seta, both arising from a common basal body shorter than the megaseta. Gonostylus elongate-oval, setigerous, with 1–2 sub-apical, medially directed stronger setae. Aedeagus wide, with prominent lateral shoulders, apex curved ventrad. Hypoproct posteriorly extending near base of gonostylus, ventral part (sternite 10) with ca. 40 scattered setae on each half. Cerci medially separate, elongated, apically widening, with setae apically and medially.

Female. Unknown.

Etymology. The species is named after Geoff Williams, the owner of Lorien Wildlife Refuge and Conservation Area, northeast of Taree, New South Wales. Geoff Williams is an authority on the natural history of the northern New South Wales, and has been recognized nationally for his service to conservation as an ecologist, biologist, author and wildlife refuge custodian.

Discussion. In having a setose anepisternum and a non-setose laterotergite, Manota williamsi sp. n. resembles M. gemella Hippa, 2007 (from Maluku Ultra, Indonesia) — into which it would run in the key by Hippa (2007). However, it differs in details of the male hypopygium as follows: (1) dorsal medial margin of gonocoxa with anterior finger-like lobe and large posterior lobe at a more ventral level (with small subapical lobe only in M. gemella ); (2) juxtagonostylar megaseta flattened, with a subapical, medially directed whip-like branch (simple, without branch in M. gemella ); (3) gonostylus elongate-oval, with 1–2 sub-apical setae stronger (with two small medial lobes in M. gemella ); (4) hypoproct wide, with ca. 40 scattered ventral setae on each half (narrow, with ca. 8 ventral setae on each half); (5) aedeagus wide, with prominent lateral shoulders (narrow with weak lateral shoulders in M. gemella ). The presence of the mid tibial organ in M. williamsi resembles the group of five species from New Zealand (cf. Jaschhof & Jaschhof 2010). Some characters in the male hypopygium of M. williamsi are also typical to the New Zealand species, e.g., sternite 9 laterally free from the gonocoxa and dorsal medial margin of the gonocoxa with anterior and posterior lobes (= positions I and II by Jaschhof & Jaschhof 2010). However, M. williamsi has the gonostylus elongate-oval without lobes, instead of being composed of several lobes as in New Zealand’s species. The similarities between M. williamsi and the New Zealand species could be homoplastic, although a similar distribution pattern is known from some other sciaroid groups, e.g., the keroplatid genus Arachnocampa Edwards ( Baker et al. 2008).
