Glenea wallacei is a species of beetle in the family Cerambycidae (longhorn beetles). It was described by the British entomologist Charles Joseph Gahan in 1897, based on specimens collected by the naturalist Alfred Russel Wallace in Sarawak, Borneo, after whom the species is named.
Taxonomy
The species belongs to the genus Glenea, subfamily Lamiinae, tribe Saperdini. It is classified within the subgenus Glenea (Glenea). The original description was published in the Annals and Magazine of Natural History (series 6, volume 19, page 482). No synonyms are currently recognized, and it remains a valid species.
Description
Adults measure 11–13 mm in length and 3.5–4 mm in width. They exhibit a distinctive coloration pattern:
- Head: Grey-pubescent with a tawny-yellow spot on the vertex.
- Prothorax: Velvety black above, dark grey laterally.
- Elytra: Testaceous (yellowish-brown) anterior disk with punctures and greyish-tawny pubescence; a transverse buff-yellow band before the middle; a dark velvety-brown central area; and a wider apical buff-yellow band. The elytral apices bear short sutural spines and longer outer angle spines.
- Underside: Grey-pubescent.
- Legs: Yellowish testaceous, with greyish tarsi on the anterior pairs.
- Antennae: Brownish black, longer than the body in both sexes.
- Males: Possess an angular tooth at the base of all tarsal claws, distinguishing them from related species.
Distribution
The species is known only from Borneo, specifically from Sarawak. It has not been recorded outside of Borneo.
Biology and Ecology
No host plants or larval details have been recorded for this species. The immature stages (larvae and pupae) remain undocumented. As with other members of the Lamiinae subfamily, larvae are presumed to bore into decaying wood, but this has not been confirmed for G. wallacei. Adults are thought to feed on nectar or sap, as is common among cerambycid beetles. The species has not been assessed for the IUCN Red List.
