Two new species of the subgenus Sabethinus of Sabethes (Diptera: Culicidae) from Costa Rica, first confirmation of members of the subgenus in Central America

Abstract

Two new species of Sabethes subgenus Sabethinus (Diptera: Culicidae) from Costa Rica are formally named Sa. andreae and Sa. theresae. Descriptions consisting of differential and diagnostic morphological characters are provided for adults, male genitalia and fourth-instar larvae. The male genitalia and the fourth-instar larva and pupa of both species are illustrated. The species are compared with the four previously described species known to occur only in South America, i.e. Sa. idiogenes, Sa. intermedius, Sa. melanonymphe and Sa. xhyphydes. A new country record for Colombia is reported for Sa. xhyphydes and keys are provided to distinguish the adults and larvae of the six species.
