Introduction

As with Anzygina honiala (Kirkaldy) and A. lubra (Kirkaldy), this species appears to have been based on a single female syntype, possibly a holotype by monotypy, but unlike those two species, A. melanogaster has distinctive markings which has allowed the female syntype to be allied with males. The species is therefore recognisable and appears to be widespread in southeastern mainland Australia.

Tegmina subhyaline. Clavus and costal cell pale yellowish brown. Wings iridescent, veins pale brown. Legs pallid. Abdomen black. Vertex about as wide as an eye. Length: 3 mill. (Kirkaldy 1906).

Head creamy yellow with transverse brown smudges along anterior margin. Pronotum cream with arcuate brown mark laterally near front margin on each side with two small brown spots medially and three small brown spots on each side behind lateral end of arcuate line. Scutellum cream with dark brown triangles. Tegmen whitish with yellow infusions along suture and along anterior margin. Male genitalia: pygofer dorsal process variable in shape from triangular to bluntly hooked. Aedeagus, in posterior view with single shaft widening from base to apex, broadly widened around apex; in lateral view, shaft tapering from base to apex and apically obliquely truncate (Fletcher & Larivière 2009).
