Lispe   sp. nov.

At a late stage of this work, after the illustrations had all been mounted, numbered and scanned, it was realised that the cercal plate dissected and illustrated for L. absentiseta   was strikingly different from the cercal plate in all other species of the cana   -group. Furthermore, the conformation of the cercal plate in other, undissected males of L. absentiseta   was typical of the species of the cana   -group ( Fig. 357a View FIGURE 357 ) and very different from that of the male dissected and illustrated here. This male has all the external morphological characters of L. absentiseta   , but the cercal plate is unlike that of any known Australian Lispe   . In the absence of further material, this male is left as “ Lispe   sp. nov.” and the illustrations of the ♂ terminalia, originally made for L. absentiseta   , are given here together with a description of the structures.

Material Examined. AUSTRALIA: Western Australia: 4 km SSW of Cape Bertholet, West Kimberley, at light, 19.iv.1977, D.H. Colless, 1♂ ( ANIC).

Ƌ terminalia. Epandrium separated from tergite 5 by syntergosternite 8, which has 2 spiracles; produced lobelike ventrally, bifurcate at apex, the inner fork connecting with the hypandrium ( Fig. 365 View FIGURES 363–366 ). Tergite 6 absent. Sternites 2–4 setulose ( Fig. 363 View FIGURES 363–366 ). Sternite 6 small, subquadrate, withdrawn beneath sternite 5 and connected to it by two elongate plates ( Fig. 364 View FIGURES 363–366 ). Surstylus absent, i.e. fused to epandrium without trace ( Fig. 365 View FIGURES 363–366 ). Cercal plate deeply divided dorsally, produced into two lobes ventrally ( Fig. 366 View FIGURES 363–366 ). Hypandrium attached at two points: to a rod originating from wall of epandrium close to upper outer edge of cercal plate; and via an apparent praegonite to lower anterior corner of epandrium. Phallic complex ( Fig. 367 View FIGURES 367 ): hypandrium branching posteriorly, the upper pair of branches fused behind base of phallus; praegonite and postgonite present, the former only loosely connected to hypandrium, the latter simple and curved; phallapodeme long but normal in structure, at mid-length connected to hypandrium by a bridge; phallus long, tubular, simple, juxta large, with small spinules; basal part without a multitoothed process.
