Abstract

Larvae, pupae, and adults reared from the pupae of Simulium (Boreosimulium) konoi were collected and recorded from Korea for the first time. I provide detailed descriptions of both immatures and adults accompanied with photographs. The subgenus Boreosimulium, previously unknown from Korea, contains 19 species in 3 species-groups worldwide and only 2 species, viz, S. (B.) konoi and S. (B.) tokachiense, are recorded from Japan. Simulium konoi is unique among the members of the subgenus by having water dropshaped denticles on the anterior portion of the cibarium in females, which is considered as an autapomorphic character so far not found in other black flies, W or inverted V-shaped ventral plate of male genitalia, and larval thorax and abdominal segments covered with short black setae. Korean specimens of S. konoi collected from two adjacent localities can readily be recognized by denticles on the cibarium in females and well-developed ventral plate of male genitalia but showed geographical variation, e.g., lacking ventral tubercle on larval abdominal segment IX. Due to the autapomorphy and other characters found in S. konoi, the current placement of the S. konoi in the subgenus Boreosimulium or species-group assignment is tentative.
