Diagnosis

1.8−2.2 mm long (mean = 2.18 mm; n = 5); 2.0−2.25 times as long as wide. This species can be identified from all other species in the region by its unique mycangiamycangia:

that includes both typical elytralelytral:
pertaining to the elytra
mycangia with conspicuous medialmedial:
situated near the median plane of the body or body part
tufts of setaeseta:
small hair-like or scale-like structure
and a pair of pit mycangiamycangia:

Distribution

Brunei, East & West Malaysia, Philippines, Thailand

Host plants

apparently highly host-selective, and recorded only from trees of the family Dipterocarpaceae (Browne 1961bBrowne 1961b:
Browne FG. 1961b. The biology of Malayan Scolytidae and Platypodidae. Malayan Forest Records 22: 1-255., Wood and Bright 1992Wood and Bright 1992:
Wood SL, Bright DE. 1992. A catalog of Scolytidae and Platypodidae (Coleoptera), Part 2: Taxonomic index. The Great Basin Naturalist Memoirs 13: 1-1533.).

Remarks

Browne (1961b) notes that the species attacks trees of any size down to about 5 cm diameter, and has been known to attack newly sawn, unseasoned boards in a sawmill.
