SYSTEMATICS Mantispidae (Neuroptera) of Mexico: Distribution and Key to Genera 1 DANIEL REYNOSO-VELASCO AND ATILANO CONTRERAS-RAMOS Instituto de Biologõ´a, UNAM, Departamento de Zoologõ´a, Apdo. Postal 70-153, 04510 Me´xico, D.F., Mexico Ann. Entomol. Soc. Am. 101(4): 703Ð712 (2008) ABSTRACT Adult specimens of the Mexican Mantispidae were recorded from the Coleccio´ n Nacional de Insectos, Universidad Nacional Auto´ noma de Me´ xico, and from Coleccio´ n Entomo- lo´ gica del Centro de Estudios en Zoologõ´a, Universidad de Guadalajara, as well as from the literature. Specimens examined (n ϭ 270) represented three subfamilies, 11 species from nine genera, and Þve morphospecies. Our studies reveal 23 species from Mexico. Distribution records are presented by country and province, as well as by locality. Six species are recorded as new state records. An illustrated key to the genera of Mexican Mantispidae is provided, as well as a list of pertinent taxonomic literature for species identiÞcation. Species richness of Mexican Mantispidae is generally discussed. KEY WORDS Neuroptera, Mantispidae, species list, Mexico The family Mantispidae belongs to the order Neu- considered. Because all of this, we decided to start roptera (Aspo¨ ck et al. 2001). Adults of this family work on Mexican mantispids by studying the spec- are known as mantid ßies, as they resemble praying imens placed in two important insect collections in mantises (Mantodea) because of the convergent Mexico. Our goal has been to update the basic characters of an elongate prothorax and raptorial knowledge on Mexican mantispids by identifying forelegs (Figs. 1 and 2; Redborg 1998). This family and recording species represented in Mexican col- comprises four subfamilies: Symphrasinae, lections and from previous literature, providing a Drepanicinae, Calomantispinae, and Mantispinae, current species list, as well as a key to genera to fa- of which Drepanicinae is absent from Mexico (Lam- cilitate an introduction to the study of this bkin 1986). group. Mantispidae is cosmopolitan in tropical and tem- perate regions, but it is most diverse and abundant in the tropics (Oswald et al. 2002).
