Lectotype, male (examined), designated by Fletcher & Condello 1993: 45, Bundaberg, Qld, ix –xii.1904 (BPBM).

Material examined. QUEENSLAND: 4 males, Ingham, Qld, 15.iii.1961, K.L.S. Harvey, light trap ( ANIC)  ; 1 male, same data as previous but 20.iv.1961 ( ANIC)  ; 1 male, Crystal Creek , 23 mi. SSE of Ingham, 18°58’05”S 146°16’E 9.xii.1968, Britton & Misko, at light ( ANIC)GoogleMaps  ; 1 male, Brisbane , vi.1904 ( BPBM)  ; 1 male, Dunwich area, Stradbroke Island, 24–26.ix.1985, at light (QDPI); 2 females, paralectotypes, same data as lectotype but “coll. Koebele ” ( BPBM)  .

Description. Head and body (Figs 1, 2) pale testaceous with brown flecking. Vertex (Fig. 2) with indistinct, narrow, transverse band subapically which lacks brown flecking, occipital suture dark brown. Tegmen (Fig. 1) whitish with brown flecking, veins pale brown, claval suture sometimes yellowish.

Genitalia. Male: Subgenital plate ( Fig. 21BView FIGURE 21) tapering into apical finger-like process. Parameres ( Fig. 21CView FIGURE 21) each with preapical lobe well developed; apical process with preapical tooth. Connective ( Fig. 21EView FIGURE 21) long with arms about as long as stem. Aedeagal shafts in posterior aspect ( Fig. 21FView FIGURE 21) broadly divergent at base and evenly curved dorsally and of even width to gonopore, bearing narrow, bifurcated apical process directed dorsomedially; in lateral view ( Fig. 21DView FIGURE 21) curved basally, then more or less straight. Basal apodeme ( Fig. 21DView FIGURE 21) short, blunt apically. Female: Apical margin of pregenital sternite ( Fig. 31AView FIGURE 31) transverse with medial section extended slightly posteriorly and shallowly concave.

Comments. This species was omitted from Knight’s (1970a) revision of the genus Hishimonus  on the basis that he did not have representative material. It is possible, however, that he recognised that the species did not fit into the genus as he had defined it. The species is reasonably well represented in collections and distributed through much of coastal Queensland. It is frequently found on species of Melaleuca  L. (Fam. Myrtaceae  ) which appear to be its natural host.
