only by generic identifications. The subfamily Neocharinaeis frequently collected, but the taxonomyof this group is too poorly understood to allow evengeneric identifications. The genera Anotylus, Belonuchus,Carpelimus, Erchomus, Homaeotarsus, Medon,Philonthus, Scopaeus, Stamnoderus, and Stenusare frequently collected in almost every part of Mexicoand Central America; species identifications inthese genera must await revisionary studies. Stilicolinacondei Jarrige is a species described from a cavein Central Texas (U.S.A.) and reported by Herman(1970) from many caves in Texas and northernMexico. Recent study, however, indicates that theMexican populations belong to an undescribed spe-cies (H. Frania, pers. comm.). This species rangessouth from near the Texas border into the Aquismonregion of San Luis Potosi (See Fig. 83). Stenopholeareddelli Herman was originally described as atroglobite from Cueva de la Mina, Tamaulipas (Herman,1969), but it has recently been found to beabundant in the endogean fauna of the high mountainregions of the Sierra Madre Oriental (Herman,pers. comm.)
