Comments. Paralasinus gigas was originally described based on materials from Attapeu, Laos, and Chanthaburi, Thailand. It is characterized by large body size (3.7–4.0 mm), markedly elongate antennomere 1 in relation to antennomere 2, unique pattern of golden smooth area of antennomeres 4–10 (according to the original description, the golden smooth area is present only on antennomeres 7–10, which is most likely based on incorrect observation), and by distinctive form of aedeagus. The additional material examined here extends the distributional range of this species to Ehammouan, central Laos.

Distribution. Laos: Attapeu, Ehammouan; Thailand: Chanthaburi (H LAVÁČ & N OMURA 2001; this paper). First provincial record for Khammouan.
