Description

3. Baiocis pernanulus (Schedl)

Crossotarsus pernanulus Schedl, 1935a: 482.

Platypus pernanulus (Schedl). Schedl 1939a: 336.

Baiocis pernanulus (Schedl). Browne 1962b: 651.

Platypus annularis Schedl, 1975: 379. Synonymy. Beaver & Liu 2018: 496.

Baiocis solomonicus Browne, 1986a: 335. Synonymy. Beaver & Liu 2018: 496.

Distribution. Australia, ‘Borneo’, Brunei Darussalam, China (Yunnan), India (Assam, W. Bengal) Indonesia (Java, Maluku), Laos, East and West Malaysia, Papua New Guinea, Philippines, Solomon Is., Thailand.

Distribution in W. Malaysia. Selangor (as Platypus peranulus [sic]).

Hosts. Based on the host records given by Schedl (1936a, 1939a, 1969a) and Browne (1961a), the species has been recorded from eight different families and is presumably polyphagous. Most of the host records for this species given by Browne (1984), Ohno et al. (1987a, b), Ohno (1990) from various countries outside West Malaysia were based on specimens identified by F. G. Browne, and should probably be referred to Baiocis orientalis Beaver & Liu, a species which has not yet been recorded from West Malaysia (Beaver & Liu 2018).

Biology. The species usually attacks cut, fallen or dying trees, and stems from c. 8 cm diameter up. Attacks may be heavy (Browne 1961a).
