VILLEGASI DENNING & BLICKLE (TRICHOPTERA, HELICOPSYCHIDAE) Johanson, K. A., 2003. The sister species of Jamaican Helicopsyche kingstona sp. n., is Mexican H. villegasi Denning & Blickle (Trichoptera, Helicopsychidae). – Tijdschrift voor Entomolo- gie 146: 33-37, figs. 1-9. [ISSN 0040-7496]. Published 1 June 2003. Helicopsych kingstona sp. n., is described from Jamaica. Its sister species, H. villegasi Denning & Blickle is found in Mexico, suggesting past exchange of biota between Jamaica and Mexico.
