<paragraph pageId="40" pageNumber="41">Diagnosis. This species group is distinguished by the following combination of characters: Head: Interfrontal seta long, subequal to length of lateral vertical seta. Antenna yellow to yellowish orange with some blackish coloration dorsally; pedicel with short ventral projection; basal flagellomere long, length nearly twice height. Large facial setae arranged in a single transverse row of about 8 setae; face of females somewhat bulbous, evenly transversely arched, mostly black dorsally, densely silvery white, microtomentose ventrally. Thorax: Anepisternum with 3-4 small setae along posterior margin. Wing moderately to strongly infumate. Forefemur of male lacking a pale, irregular, subapical annulus, bearing 1 large, posteroventral seta at apical 1/3. Abdomen: Surstylus generally bearing a basal process and generally in nearly oblique alignment with epandrium; postgonite with robustly developed lobe bearing numerous setulae apically; phallus mostly sclerotized, convoluted; ejaculatory apodeme generally well-developed, at least as long as phallapodeme, with expanded apex.</paragraph>

Discussion. Species of this species group share, with species of the ambiguus group, and only with them, a postgonite with a robustly developed lobe that bears numerous setulae. In other species of

|
, the lobe of the postgonite, which is generally less well developed, bears fewer than four apical setulae, and fewer than six setulae overall. The nigritarsus and ambiguus groups also share an ejaculatory apodeme that is generally well developed, at least as long as the phallapodeme, but this character state is also present in
