Baiocis angustulus (Schedl)

Platypus angustulus Schedl, 1942: 202 .

Baiocis angustulus (Schedl) : Browne 1962: 651.

Taxonomy: The species is known with certainty only from the female holotype (NMW, examined) collected in 'Teibodas, Giava' (i.e. on the Indonesian island of Java). Wood and Bright (1992) cite syntypes, but the species was described from a single specimen. It is placed in Baiocis on the basis of multiple characters as given above for B. angustipennis , and the presence of a weak carina on the metanepisternum. Schedl's (1942) description is rather brief, so some supplementary details are given here. The frons is angularly separated from the vertex, more so at the sides than in the middle, but lacks a carina. The femoral grooves are clearly more strongly angulate anteriorly, and the upper margin of the groove is carinate in the anterior half, the carina extending about the same distance beyond the anterior angle. The elytra are 2.1 times as long as the pronotum. The posterolateral angles of the elytra are bluntly rounded. The vertical face of the declivity is angularly separated from the dorsal surface without a carina, and is about five times as wide across both elytra as it is deep, with a shallow, lunate impression bearing many short, erect hairs. The metanepisternum bears a very weak carina anteriorly. It is possible that Baiocis sumatranus , described above, is the male of the species, but at present the male and female cannot be definitely associated.

Distribution: Indonesia (Java).

Biology: Unknown.
