Material examined. 1♀, Site 8, spraying [18A272] ( Fig. 5A).

Species diagnosis. Kishii (1970).

Remarks. Quasimus uguriensis was divided into 3 subspecies: Quasimus uguriensis uguriensis Kishii, 1970 from Uguru Island, Shikoku; Q. uguriensis okicola Kishii, 1970 from Okinoshima Island, Shikoku; and Q. uguriensis heianus from Kuchinoerabu Island, in the Ôsumi Islands. The 3 subspecies are similar in the shape of the male aedeagus, but differ in the hind angle of the pro- thorax, scutellum, and metasternum ( Kishii 1976a). The specimen examined is similar to the specimens of the type series of Quasimus uguriensis heianus in the shape of the scutellum ( Kishii 1970) and differs from the type series by the sinuate hind angle of the prothorax and the carina of the metasternum obscure posteriorly. There are no detailed studies of morphological variation either among allopatric populations or among sympatric specimens because there are few records of this species. Future efforts to collect more specimens are needed to understand the morphological variation of this species. In this study, we determined that the specimens examined were Q. uguriensis heianus based on similar scutellum and its distribution.

Bionomics. The specimen examined was collected under a stone near the mouth of a river, together with Zorochros (Pronegastrius) humeralis yakuensis ( Kishii 1976a) .
