Simulium (Hearlea) chiriquiense Field

Simulium (Hearlea) chiriquiense Field, 1967: 194–199, Figs. 1 –30; Vargas, Travis, Díaz Nájera, & Fallas, 1977: 137.

We were unable to examine topotypical material of this species. Based upon the original description, it could be considered conspecific with S. (Hearlea) ethelae Dalmat based upon structure of the pupal gill. Material from Costa Rica identified as S. chiriquiense by Vargas et al. is similar to that of S. (H.) capricorne, based upon illustrations of the pupa (Figs. 3, 4). Both adults cannot be reliably differentiated from those of other S. (Hearlea) species.

Distribution: Panamá: Chiriqui, cerro Punta (Boquete); Costa Rica: San José.
