Calomutilla Mickel, 1952

Cambra, Roberto A., Brothers, Denis J. & Quintero, Diomedes, 2020, Review of Calomutilla Mickel, 1952, a new species, and comparison with Pertyella Mickel, 1952 (Hymenoptera: Mutillidae), Zootaxa 4789 (2), pp. 466-480 : 467-468

Key to species of Calomutilla Mickel

This key is a first attempt to account for both sexes of the described species of the genus. The couplets covering the females are based on Mickel’s (1952) key. In addition to the information provided in this paper, those for the males utilize the original description of C. anceps by Mickel (1952) and notes and drawings of its holotype (in UMSP) made by D.Q. in 1996, neither source providing sufficient details of the genitalia (notably the penis valve) nor various other characters which seem potentially to be useful for species differentiation. The female holotype of C. williamsi ( Figs 15, 16 ) and the male holotype of C. anceps were collected at the same place (Blairmont, British Guiana [ Guyana], female October 1923, male September 1923, col. F.X. Williams) and they probably represent the same species. Mickel (1952) suggested that his new species, Ancipitotilla anceps , was likely the male of a species of Lophomutilla Mickel, 1952 , but that has proved to be incorrect; males of Lophomutilla were originally described as Mammomutilla Mickel, 1952 (synonymized by Quintero & Cambra 2001) and Paramutilla Mickel, 1973 (synonymized by Quintero & Cambra, 1996).
