Composition. This tribe, as defined here, includes the genera Gertschius View in CoL , Serradigitus View in CoL , Stahnkeus View in CoL , and Wernerius View in CoL .

Distribution. Mexico ( Baja California, Baja California Sur, Coahuila, Sonora), USA ( Arizona, California, Nevada, New Mexico, Utah).

The tribe Stahnkeini is distributed primarily in the southwestern United States, Baja California peninsula, and extreme northern areas of mainland Mexico; see map in Fig. 202 View Figure 202 and discussions of genera below.

Diagnosis. Basal pectinal teeth (1 to as many as 4) of female lacking sensorial areas; median denticles ( MD) of chelal fingers serrate; MD + OD denticle density quotient low, 30–42 (37); mating plug barb of hemispermatophore smooth; one ventral distal spinule pair on leg tarsus; chelal trichobothrium Db located on or ventral of digital ( D1) carina; position of fixed finger trichobothria ib–it variable, from midfinger to slightly proximal of basal inner denticle ( ID), based on species adult size; patellar trichobothrium v 3 positioned distal to et 3; ventral edge of cheliceral movable finger with well developed contiguous serrula (21–37 tines).

Taxonomic history. The tribe was recently established by Soleglad & Fet (2006) for vaejovid genera Serradigitus View in CoL and Stahnkeus View in CoL . At that time, the tribe was not formally assigned to any subfamily. Graham & Soleglad (2007) added the genus Gertschius View in CoL to tribe Stahnkeini . Here, we formally place Stahnkeini in subfamily Syntropinae , which is reestablished here from synonymy, along with the nominotypic tribe, Syntropini , established here. We also add a new genus, Wernerius View in CoL .
