Figure 1 . Odyneropsis apache Griswold & Parker , female, lateral view. Scale line = 1 mm. DIAGNOSIS: This species is readily distinguished by its ferruginous body, the yellowish pubescence, and the deeply infuscate wings. It is very similar in punctation and morphology to the other two Mexican species. The three species form a group within Odyneropsis s. str. characterized by a sturdy first metasomal segment and proportionally shorter legs. Besides differences in color, O. apache lacks the branched hairs that cover the scutum of O. apicalis , and the vertex is punctate throughout, lacking the impunctate, polished areas present in O. chamelae . For a full description of O. apache , the reader is referred to Griswold and Parker (1999) . DISTRIBUTION: México , state of Jalisco . USA , state of Arizona .
