Records of phlebotomine sand flies (Diptera, Psychodidae, Phlebotominae) with a description of a new species of Sergentomyia França & Parrot from Khao Yai National Park, Thailand Author Curler, Gregory R. text Zootaxa 2011 2806 60 68 journal article 10.5281/zenodo.277084 e04b1b7a-0014-46f7-976d-663a5dcbe0a6 1175-5326 277084 Phlebotomus (Euphlebotomus) sp. Phlebotomus (Euphlebotomus) argentipes Annandale & Brunetti 1908 , the major vector of visceral Leishmaniasis in India , is known to occur in Thailand ( Apiwathnasorn et al. 1989 ; Polseela et al. 2007 ). During the current study, a single female specimen of subgenus Euphlebotomus was collected in KYNP, and identified as P. argentipes using the key of Lewis (1978) . But the specimen differed somewhat from the description P. argentipes in that the spermathecae are segmented, but more globular than elongate. P. argentipes has long been suspected as a complex; however, as shown by Muller et al. (2007) , there are other species of subgenus Euphlebotomus in Thailand that are morphologically similar to P. argentipes , but are indeed distinct species. A new species will not be described based on this single female specimen, but future collections of males and females will help determine whether this specimen represents a new species.
