Lispe caespitosa   sp. nov.

( Figs 284–294 View FIGURE 284 View FIGURES 285–289 View FIGURES 290–292 View FIGURES 293–294 )

Diagnosis. In the group of species with a seta on posterior apical margin of hind coxa, the male of L. caespitosa   can be recognised by its dark palpus and the conformation of hind tibia and tarsomeres ( Fig. 287 View FIGURES 285–289 ).

Etymology. This name is from the Latin “caespes” (“turf”) and refers to the tufted armature at the tip of the male hind tibia and tarsomere 1 ( Fig. 287 View FIGURES 285–289 ).

Description ♂ ♀. Head ( Fig. 285 View FIGURES 285–289 ). Ground-colour black. Frons at broadest point 0.34 (♂) or 0.30 (♀), at lunula 0.27, of maximum head-width (frontal view). Fronto-orbital plate uniformly pruinose, together with parafacial, face, gena and most of occiput silvery-white pruinose, more yellow in ♀ except for occiput, face and facial ridges tinged with yellow, and a distinct brown spot at lunula; frontal triangle yellowish- to brownish-grey, very broad, much of frontal vitta suppressed. Lower orbital seta short. Parafacial narrow, half as broad as postpedicel; entirely setulose. Antenna black; postpedicel short, 2.0 times (♂) or 2.7 times (♀) as long as broad, falling short of mouthmargin by its length (♂) or slightly less than this (♀). Arista plumose, the hairing at widest point twice width of postpedicel. Vibrissa short. Gena broad, 0.18 of vertical eye-length; genal setae strong and dense. Palpus brown, stalk yellow, strongly swollen at tip ( Fig. 286 View FIGURES 285–289 ).

Thorax. Ground-colour black. Scutum rather densely grey dusted; postpronotal lobe, notopleuron and pleura very light grey; scutellum entirely brown dusted. Viewed from behind, scutum thinly and irregularly grey dusted, with a broad dark brown patch occupying the whole area between dc, from neck to 1st post dc, this dark area with a pair of paler dusted narrow paramedian vittae (♂) or with a single broad median pale vitta (♀). Anterior spiracle yellowish. Acr in 4–5 irregular rows at suture. Dc 2+3. 2 pprn. 1+1 ia. 1+1 sa, both strong. 1 strong and 1 weaker proepisternal setae. 1 strong proepimeral, slightly shorter than the strong proepisternal, with 4 adjacent setulae. Anepisternum with a very short seta in upper anterior corner; posterior row with 3 strong and 3 weak setae. 3 strong kepst, lower one closer to posterior than to anterior. Meron bare below spiracle and above hind coxa. Scutellum with disc densely setulose, 2 irregular rows descending on to sides, otherwise sides and ventral surface bare.

Legs. Black, except for reddish knees. Fore coxa bare behind. Fore femur with a row of short spinules on av surface; pv row complete, the setae long and fine, longer than femoral depth, interspersed with multiserial v to pv spinules; pd row complete. Fore tibia without submedian seta; with d, pd and pv apical setae, and also with a distinct ad apical. Fore tarsomeres rather short, without modifications. Mid femur with only short setulae on av surface; on pv surface with fine setae in basal half and thereafter only with short setulae; basal half also with a row of short strong a setae, culminating in a strong seta at middle, these all much weaker in ♂ than in ♀; 2 p preapicals. Mid tibia with 1 strong p seta; with strong ad, av, v, pv and p apicals, the p short, the ad apical a little before apex. Mid tarsomeres without modifications. Hind coxa with a seta on posterior apical margin. Hind femur setulose on av surface, and 1 fine seta at middle in ♂ and another before apex; pv surface with 4–5 long fine setae in basal half, otherwise only with setulae; ad row complete; 1 d preapical. Hind tibia of ♂ with 1 ad, with the ground-setulae on this surface long and erect; 1–2 av seta; tibia at and just before apex with numerous long fine setae and setulae on all surfaces, and thus with no distinct apical setae ( Fig. 287 View FIGURES 285–289 ); in ♀ with 1 ad and with d and ad preapicals, all three very strong, 1 av, and av and pv apical setae. Hind tarsus of ♂ with basal tarsomere slightly swollen at tip of pv surface and there covered with a short brush of setulae ( Fig. 287 View FIGURES 285–289 ); without modifications in ♀.

Wing. Clear. Tegula black, basicosta yellow. Crossvein r-m placed below the point where vein R1 enters costa; dm-cu weakly sinuous, longer than apical section of vein CuA1. Vein M running straight to wing-margin. Calypters white, margins yellow. Knob of haltere black.

Abdomen. Ground-colour black. Tergites light grey dusted, with a pair of small poorly defined spots on tergite 3 in ♂, these spots larger and more semi-circular in ♀, and a broad black central spot on tergite 4 that runs down on to sides of tergite and encroaches broadly on tergite 5 ( Figs 288–289 View FIGURES 285–289 ). ♂ epandrium grey dusted. ♀ ovipositorwith the exposed tergites grey dusted. Sternites 1–5 grey dusted, sternite 5 of ♂ shining. Setae only present on tergite 5, with 2 pairs of median and 2 of lateral discals (♂) or 2–3 pairs of discals (♀), and 4–5 (♂) or 2 (♀) pairs of erect marginals. Sternites 2–4 with sparse setulae ( Fig. 290 View FIGURES 290–292 ).

Ƌ terminalia. Epandrium separated from tergite 5 by syntergosternite 8, which has 2 spiracles; without large setae; weakly produced lobe-like ventrally ( Fig. 291 View FIGURES 290–292 ). Tergite 6 absent. Sternite 6 present as a small plate, withdrawn beneath sternite 5 and connected to it by a pair of broad outgrowths from the sternite. Surstylus absent, i.e. fused to epandrium without trace ( Fig. 291 View FIGURES 290–292 ). Cercal plate divided dorsally and ventrally ( Fig. 292 View FIGURES 290–292 ). Hypandrium attached at two points: to a rod originating from wall of epandrium close to upper outer edge of cercal plate; and via a tiny apparent praegonite to lower anterior corner of epandrium. Phallic complex ( Figs 293–294 View FIGURES 293–294 ): hypandrium with a pair of processes at posterior end that meet and unite with base of epiphallus; praegonite and postgonite present, the postgonite curved outwards ( Fig. 294 View FIGURES 293–294 ); phallapodeme large, at mid-length joined to hypandrium by a small bridge; phallus long, tube-like, simple, juxta large, without spinules, without paired processes at base.

♀ ovipositor. Not examined.

Biology. Adults have been collected among mangroves.

Distribution. Known only from Australia (V, SA).
