Casey 1912 :172 Type material. HOLOTYPE , by monotypy, (sex undetermined) labeled: a) Orange bordered white circle reading “ Type ”; b) “Villa Lerdo, / Durango. / Hoge.”; c) “ Asida / furcata, Ch . ”; d) “Sp. figured; e) “B.C.ACol.

Dorsal habitus of the Stenomorpha furcata species-group: 1) Stenomorpha furcata (male); 2) Stenomorpha granicollis (male); 3) Stenomorpha wickhami (male); 4) Stenomorpha roosevelti (holotype). FIGURES 5–8. Lateral view of the Stenomorpha furcata species-group: 5) Stenomorpha furcata (male); 6) Stenomorpha granicollis (male); 7) Stenomorpha wickhami (male); 8) Stenomorpha roosevelti (holotype). Additional material examined. ( 33 specimens ). MEXICO : Durango and Coahuila. USA : Texas (Brewster, Presidio, Terrell, Upton, Val Verde Counties). Diagnosis. S. furcata can be distinguished from other members of the furcata group by its sparsely clothed and finely punctate pronotal disc, which is more strongly gibbose in lateral view than are those of the other species, and its tuberculate prosternum. Remarks. Triplehorn and Brown (1971) presented the first records of S. furcata within the United States and discussed variation within and between S. furcata specimens from differing localities. They examined differences in elytral sculpturing and marginal carina bifurcation between populations and concluded that, while there are slight geographical variations, all of the observed variation fell within the range of S. furcata .
