Pseudosermyle Caudell, 1903

Type-species: Pseudosermyle banksii Caudell, 1903: 871 , by original designation.

Comments. Caudell (1903: 867) established Pseudosermyle for five United States species, provided a key and designated the newly described P. banksii from Texas (Brazon County) as the type-species. Zompro (2001a: 216) provided a brief diagnosis of the genus and a preliminary list of species. Currently ( Otte & Brock, 2005: 291 ff.), 21 species are attributed to Pseudosermyle , several of which are only known from the type-specimen(s) or a single sex. Three new species from Mexico are described below. Due to the very fractional knowledge of the genus no generic diagnoses can be provided with confirmation. The very diverse structure of the male genitalia and the cerci in particular, indicate the genus as presently treated may contain several distinct generic units. However, any broader discussion on this subject or eventual splitting of the genus is only possible with extensive research and examinations of the complete vast amount of museums specimens and realisation of new collections in Central America. The aim of the present paper restricts to the descriptions of the three new species found among material from the UNAM collection.

Therefore the keys presented below can only be provisional but appear to be warranted for easier determination.

Distribution. Southwestern USA and Central America.
