Type series. Lectotype ♂ (here designated) (Figs. 18–22): Australia [printed in purple] | Typus! [printed on red] | testaceipennis type Ohaus [handwritten] | Homotropus testaceipennis Ohaus [handwritten] | BILOBATUS TESTACEIPENNIS (OHAUS) Det. A.B.T.

Other material examined. AUSTRALIA. VICTORIA. 1♂, Alexandra, 6.xii.1954, A. N. [MV]; 1♂, Hazelwood [Churchill], 16.i.[19]48, J. H. Courtenay [ANIC].
Diagnosis (Figs. 18–19, 21–22). Body 13–14 mm long; head, pronotum, scutellum, and pygidium dark brownish black with a green tinge, clypeus suffused with yellowish brown; elytra brownish yellow with intervals moderately darkened to brown; coxae and remaining abdomen reddish brown. Upper surface of clypeus deeply depressed, lateral margin notched just behind anterior edge that is slightly convex. Protarsus with tarsomeres 1–4 much longer than tarsomere 5. Description by Carne (1958: 215; mentum of male Fig. 110; head of male, lateral view Fig. 111; head of male, dorsal view Fig. 112; right protibia of male Fig. 113; parameres of male Fig. 114); Weir et al. (2019: dorsum Plate 68A).
Remarks. Ohaus (1901) described this species from the male but did not state how many specimens he saw, making the composition of the type series unknown. Carne (1958) saw a “Type ♂ ” in ZMB and Cassis & Weir (1992) referred to a “ holotype male” in ZMB, but both provided no label data to identify the specimen and Cassis & Weir gave no reason why they considered it a holotype; neither explicitly indicated that a particular specimen was selected from the type series to serve as the name-bearing type (International Commission on Zoological Nomenclature 1999, Article 74.5). I designate the specimen in ZMB as the lectotype to stabilise its identity and have labelled it as such.
Distribution (Fig. 23). Known from the La Trobe Valley and north into the ranges of Victoria.
