Tepa jugosa (Van Duzee)

Tepa jugosa (Van Duzee)

Thyanta jugosa Van Duzee, 1923:129 . Thyanta coloradensis Bliven, 1956: 5- 6 , pl. 1,fig. 9. NEW SYNONYMY. Tepa jugosa : Rolston and McDonald, 1984:77,80,fig. 45.

Rolston (1972) noted that the description and illustration of Thyanta coloradensis Bliven agreed in all significant respects with the characters of Tepa punctiventris , but the type specimens of Thyanta coloradensis were not available for study at that time, and Bliven's description was inadequate for proper placement of the species. The holotype of T. coloradensis has now been examined, and it is a typical example of Tepa jugosa . The holotype of T. jugosa was also examined.

Tepa jugosa is probably themost easily recognizable species in the genus. The long ostiolar rugae which widen apically separates it from all other species in the genus. Tepa jugosa has previously been reported only from Baja California, Mexico.
