Bolitogyrus strigifrons (Wendeler): Brunke and Solodovnikov 2014 (redescription; misidentification of B. pseudostrigifrons , in part)

Type material.

Holotype, examined for Brunke and Solodovnikov (2014), images used for comparison.

Diagnosis.

Within the Strigifrons group (for diagnosis, see Brunke and Solodovnikov (2014)): strigulose sculpture of elytra present and more expansive, not restricted to small lateral patch; posterior protuberances of head not creating expansive impunctate areas; abdominal tergites VI-VII with disc impunctate medially. Bolitogyrus strigifrons is most similar to B. pseudostrigifrons but can be easily recognized externally by the impunctate medial area on tergite VII and the more expansive strigulose sculpture on the elytra. The paramere is also markedly different (Fig. 2E ), with the overall shape evenly narrowed to the apex and with simple, organized marginal rows of peg setae; it is also longer than the median lobe. Additionally, the median lobe in ventral view is more strongly convergent to a narrower apex (Fig. 2C )

Distribution.

In its revised sense, B. strigifrons is known only from the holotype male, collected from an imprecise locality in Veracruz state, Mexico ( “Jalapa”).

Comments.

At the moment, sister species B. pseudostrigifrons (Hidalgo) and B. strigifrons (Veracruz) appear to be broadly allopatric but more collecting is needed in Veracruz and Puebla states at medium elevations to verify this.
