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

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 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 and Stahnkeus . At that time, the tribe was not formally assigned to any subfamily. Graham & Soleglad (2007) added the genus Gertschius 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 .

Discussion. See discussion of genera below.
