Dissomphalus falcatus Evans, 1962   ( Fig. 104–105 View FIGURES 100–117 )

Dissomphalus falcatus Evans 1962: 67   , 69, 72–73, 1964: 45, Sarazin 1986: 295, Gordh & Moczar 1990: 222.

Diagnosis. — Head as figure 104. Mandible bidentate. Clypeus subtrapezoidal. Frons somewhat strongly coriaceous, punctures large, shallow. Vertex badly convex, corners rounded. Metasomal tergite II with pair of large, deep, and subtriangular lateral depressions, distant each other 1.5 X their diameter, nearly touching the posterior margin of tergite I, with inner and outer margins hairy, with an inner large pit, with tuft of hairs ( Fig. 105 View FIGURES 100–117 ).

Material examined. — HOLOTYPE: male, MEXICO, Mexico, Ixtapan la Sal , 5,500 feet, 9.VIII.1954, J. G. Chillcott col. ( CNCI, type nº 7,550).  

Comments. — This species is known only from the type, and its genitalia is missing, but Evans (1962) draw it, which is peculiar by having aedeagus with elongate ventral ramus and apical lobes of dorsal body. This species belongs to bicavatus   species­group, but here the tergal processes are subtriangular, not elliptical.

bisulcus   species­group

Diagnosis. — Male. Metasomal tergite II with two median horizontal and linear hairy tufts and nearly touching each other placed in a shallow depression.
