(Figs 295–303)
Diagnosis. In the group of species with a seta on posterior apical margin of hind coxa, L. glauca is most similar to Lispe floccosa but can be distinguished by the relatively simple hind tarsomeres (Fig. 297).
Etymology. The species name is the feminine form Latin adjective “glaucus” (= grey”) and refers to the general appearance of the species.
Material examined. Holotype ♂. AUSTRALIA: Western Australia: Thomas River estuary, Esperance District, Malaise trap, 8.xi.1977, D.H. Colless (ANIC). Paratype 1♂. AUSTRALIA: Western Australia: Cranmore Park, bred, xi.1933, M.E. Fuller, 1♂ (very damaged) (ANIC).
Description ♂ (♀ not known). Head (Fig. 296). Ground-colour black. Frons at broadest point 0.4, at lunula 0.35, of maximum head-width (frontal view). Fronto-orbital plate uniformly pruinose, together with frontal
triangle, parafacial, face, gena and most of occiput silvery-white pruinose; frontal triangle very broad, frontal vitta totally suppressed. Lower orbital seta short. Parafacial broad, as broad as postpedicel; bare on upper third. Antenna black, only apical edge of pedicel obscurely orange; postpedicel short, 2.0 times as long as broad, falling short of mouth-margin by its length. Arista plumose, the hairing at widest point equal to width of postpedicel. Vibrissa strong. Gena broad, 0.26 of vertical eye-length; genal setae sparse anteriorly and dense behind. Palpus brown, stalk yellow, strongly swollen at tip (as in L. caespitosa, Fig. 286).
Thorax. Ground-colour black. Scutum and scutellum rather unevenly light grey dusted; postpronotal lobe, notopleuron and pleura thinly grey dusted. Viewed from in front, scutum wholly silvery dusted; in posterior view, with the grey dust very restricted, limited to a light grey band along suture, running from notopleuron to dc, and with a pair of post grey vittae between dc and ia that coalesce posteriorly to form a broad grey median patch from 2nd post dc to scutellum; scutellum grey dusted. Anterior spiracle yellowish. Acr in 5 irregular rows at suture. Dc 2+3. 2 pprn. 1+2 ia. 1+1 sa, both strong. 1 strong and 1 weaker proepisternal setae. 1 strong proepimeral, slightly shorter than the strong proepisternal, with 9–11 adjacent setulae. Anepisternum with a very short seta in upper anterior corner; posterior row with 3 strong and 2 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, knees hardly reddish. Fore coxa bare behind. Fore femur with only short setulae on av surface; pv row complete, the setae long and fine, longer than femoral depth, interspersed with multiserial v to pv setulae; pd row complete. Fore tibia without submedian seta; with d, pd and pv apical setae, and also with a distinct ad apical. Fore tarsomeres 2–5 rather short, none with any modifications. Mid femur with very short av setae in basal half, continued as a row of spinulose setulae; pv surface with longer setae in basal half, as long as femoral depth, continuing as a row of erect fine setulae; basal half also with a row of short strong a setae, culminating in a strong seta at middle; 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 with 5 av setae in apical half, the longest longer than femoral depth, preceded by several erect setulae; pv surface with several short setae in basal half, merging into a row of dense fine setulae; ad row complete; 1 d preapical. Hind tibia with 1 ad, with the ground-setulae on this surface rather long; 1 av seta (with an adventitious short second seta on one side); ad and d preapical setae long and strong; 1 av and 1 pv apical setae. Hind tarsus with basal tarsomere not swollen, with a uniform covering of short dense brush-like setulae along p to pv surfaces (Fig. 297).
Wing. Clear. Tegula black, basicosta yellow. Crossvein r-m placed slightly apicad of the point where vein R1 enters costa; dm-cu straight, longer than apical section of vein CuA1. Vein M running straight to wing-margin. Calypters white, margins creamy. Knob of haltere black.
Abdomen. Ground-colour black. Tergites grey dusted, slightly damp in the holotype but apparently unmarked except for very weakly indicated dull spots on tergites 3 and 4 (Fig 298); the paratype with syntergite 1+2 wholly dark. Epandrium grey dusted. Sternites 1–4 grey dusted, sternite 5 shining. Setae only present on tergite 5, with 1 pair of median and 3 of lateral discals, and 5 pairs of erect marginals. Sternites 2–4 with sparse setulae (Fig. 299).
Ƌ terminalia. Unusually large (cercal plate drawn at the same scale as the other species, but lateral view and aedeagus at a smaller scale). Epandrium separated from tergite 5 by syntergosternite 8, which has 2 spiracles; without large setae; weakly produced lobe-like ventrally. Tergite 6 absent. Sternite 6 present as 2 small symmetrical plates, withdrawn beneath sternite 5, and connected to sternite 5 by a pair of broad projections from the sternite. Surstylus absent, i.e. fused to epandrium without trace (Fig. 300). Cercal plate divided dorsally and ventrally (Fig. 301). 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 (Fig 302– 303): hypandrium with a pair of long finger-like processes at posterior end that meet and unite with base of epiphallus; praegonite and postgonite present, the latter very long and incurved with their tips crossing (Fig. 303); phallapodeme large, at mid-length joined to hypandrium by a small bridge; phallus long, tube-like, simple, juxta large, without spinules, with a pair of small flap-like processes flanking at base.
