   Chaetophyes bicolor Schmidt, 1918 by original designation.

Introduction

Chaetophyes compacta and C. vicina are common and widespread in eastern Australia and frequently collected in large numbers in light traps. Most individuals of all species are shiny greenish brown on the head and thorax with extensive dark brown areas on the tegmina, although males of C. compacta are usually entirely dark brown to black, occasionally with green heads and C. pulcherrima has some vague striping on the mesonotum. The anterior prominence of the head, which can be quite snout-like in profile, varies within species. The genus is restricted to Australia and New Guinea.

Diagnosis

Body of small to medium size, rather robust to fairly slender, distinctly broader than deep in profile. Head slightly narrower than pronotum. Ante- and postclypeus evenly convex in female' postclypeus usually weakly keeled in male. Pleurostome broader than lorum, separated from lorum by a long deep suture; maximum length of gena proper and minimum breadth of pleurostome subequal; maxillary plate slightly exposed. Eye shorter than broad, its inner margin weakly curved and distinctly angulate at lower end; outer margin not touching hind margin of head. Crown weakly depressed, irregularly rugose, rarely smooth; its anterior margin in male broadly rounded, in female subangulate or strongly produced at middle; tylus usually much narrower than eye and hardly broader than side piece of vertex. supra-antennal triangle well defined, well visible in vertical view of crown; ocelli much closer to each other than to eyes. Pronotum coarsely rugose, usually with some intermingling punctures; anterolateral margin carinated and weakly reflexed. Scutellum very low, flat or nearly flat. Tegmen short, broad, transparent, apically or entirely smooth, basally more or less punctate; basicostal area broad, distinctly depressed; disc of corium convex; apical and preapical cells distinctly concave; veins prominent, deeply pigmented; venation rather similar to that in typical Hindola, but R branched far beyond middle of costal margin, apical cells short but large, rm1 shorter, apical abscissae of Rs and M not stronged switched toward anal margin; corial appendix usually reaching 1/2 of apical corial margin, rarely vestigial. Hind tibia with 1-2 lateral spines, when 2, then the major one about 2/5 as long as breadth of tibial apex; inner and outer apical lobes of hind tarsomeres subequal in length. Female anal segment partly concealed, ovipositor sheath nearly vertical (Maa 1963).
