Middle tibiae a little expanded in comparison with those of female. First segment of middle tarsi slightly thickened, very weakly bent in dorsal view. Fifth abdominal sternum shallowly emarginate. Emargina- tion of sixth sternum (Fig. 232) very deep, triangular, extending less than half length of sternum; lateral lobes of sternum strongly produced as slender, strongly divergent processes, subacute at apex. Pygidium not produced. Genitalia as in Figure 305; aedeagus with a single ventral hook (apical hook obsolete). Female. Antennae not reaching middle of pronotum; segment III slightly wider than IV. Sixth abdominal sternum as in Figure 278; lateral lobes of sternum acute. Type locality. Mexico. Geographic distribution. Central Veracruz (Jalapa) to eastern Guer- rero and central Oaxaca. (See Fig. 22.) Seasonal distribution. Unknown. Records. MEXICO: Country label only, 4 (including lectotype). Guer- rero: State label only, 4; Amula (Champion, 1892); Mochitlan, 1. Oaxaca:. Fig. 22.
