Tepa brevis (Van Duzee)

Thyanta brevis Van Duzee, 1904: 53 , 56 - 57.

Tepa brevis : Rolston and McDonald, 1984:77, 80, fig. 44.

Van Duzee described Thyanta brevis in 1904 from 10 specimens collected at Grand Junction, Colorado. Although he placed " holotype " and " paratype " labels on the pins with the specimens, he did not actually make these designations in his original description. Strict adherence to the rules of nomenclature dictates that these speci mens should be considered syntypes, and lectotype and paralectotype designations are required.

Of the original syntype series only one male and one female were located. The male specimen labeled " Gnd Junc Col. 7 - 28 - 00 / E P Van Duzee collector / HO LOTYPE brevis " ishere designated as the lectotype, and the female specimen labeled " Gnd Junc Col. 7 - 28 - 00 / E P Van Duzee collector / PARATYPE brevis " is desig nated the paralectotype.

Tepa brevis can be recognized by the relatively short ostiolar rugae which are evanescent apically when viewed in profile. It also has the jugal margins nowhere parallel with the apex of the head narrowly rounded. Tepa rugulosa and T. yerma both have the ostiolar rugae relatively short, but in both of these species it is truncate apically when viewed in profile; also the lateral margins of the head are subparallel for some distance between the eyes and the apex. Specimens of T. brevis have been examined from Arizona, California, Colorado, Nevada, New Mexico, Texas, Utah, and the Mexican states of Baja California Norte, Chihuahua, Nuevo Leon, and Sonora .
