Description of Triatomahuehuetenanguensis sp. n. a potential Chagas disease vector (Hemiptera Reduviidae Triatominae)

摘要

A new species of the genus Triatoma Laporte, 1832 (Hemiptera, Reduviidae) is described based on specimens collected in the department of Huehuetenango, Guatemala. Triatomahuehuetenanguensis>sp. n. is closely related to T.dimidiata (Latreille, 1811), with the following main morphological differences: lighter color; smaller overall size, including head length; and width and length of the pronotum. Natural Trypanosomacruzi (Chagas, 1909) infection, coupled with its presence in domestic habitats, makes this species a potentially important vector of Trypanosomacruzi in Guatemala.
