Callilanguria stenosoma ( Harold, 1879)

Fig. 10

Languria stenosoma Harold 1879: 64 . Type locality: Borneo , Sarawak. Type depository: MCSN .

Callilanguria stenosoma: Fowler 1908: 21 .

Remark. Body length: 12–14 mm (original description). Harold (1879) mainly described the color of this species; he noted that this species could be distinguished from C. luzonica by antennomere VII being triangular; the apices of the elytra are truncated and oblique, with small denticles; the outer angle extends further posteriorly than the sutural angle. In addition, the body size is smaller than in C. luzonica . The most reliable characteristic is the shape of the apices of the elytra.
