Diagnosis.

Has a rather short and stout abdomen with uniformly arranged circular depressions. The male is black with black or brown wings and the female is reddish with brown wings, darker apically. Body length 9-12 mm; wing length 7-9 mm. Flight time April - August.

Most similar to Saropogon senex and S. purus . Differs from S. purus because S. abbreviatus has short apical scutellar macrosetae, whereas the apical scutellar macrosetae of S. purus are longer than the length of the scutellum. Differs from S. senex because S. abbreviatus has short discal scutellar macrosetae, and S. senex has none.

Distribution.

USA: California, Texas; Mexico: Baja California, Tamaulipas.
