TY - JOUR T1 - Key to the Cosmetidae (Arachnida, Opiliones) of Central America, with notes on penis morphology and sexual dimorphisms JF - Zootaxa Y1 - 2010 A1 - Townsend, Victor R A1 - VĂ­quez, Carlos A1 - VanZandt, P.A A1 - Proud, Daniel N SP - 1 EP - 26 KW - Arachnida KW - Central America KW - Cosmetidae KW - Laniatores KW - Opiliones KW - taxonomic key AB -

To facilitate identification of harvestmen of the family Cosmetidae in Central America, we developed dichotomous keys that distinguish the 33 known genera and the 133 described species for this region. Couplets are based upon characters found in the literature and examinations of museum specimens. Important characters include the number of tarsomeres on leg I, armature of the dorsal scutum, free tergites and legs, as well as the coloration and relative length of the body and legs. In addition, we provide a summary of sexually dimorphic features and comment on the potential usefulness of penis morphology and coloration as characters for distinguishing taxa.
