Treatment

Omocerus bolivianus ( Boheman, 1857) stat. restit.

Tauroma boliviana Boheman, 1857: 20 (original description).

Type locality. ‘Bolivia’.

Type material examined. SYNTYPES: ♀, pinned, ‘ Bolivia [w, hw, cb] || Chevrol. [w, p, s] || Type. [w, p, s] || NHRS- JLKB | 000022424 [w, p, cb]’ ( NHRS); ♀, pinned, ‘ E. Coll | Chevt. [w, p, cb] || Tauroma | Boliviana | (Chv) Bhn | Bolivia [w, hw by Chevrolat, s] || 67·56 [w, p, s]’ ( BMNH) .

Remarks. BOHEMAN (1857) described Tauroma boliviana from unknown number of specimens and stated ‘Dom. Chevrolat. Mus. Holm.’ as type depository. Latter on, he indicated this taxon as present in his collection ( BOHEMAN 1862). I have examined two specimens coming from the collection of Chevrolat, one retained by Boheman and the other purchased by Hamlet Clark. I consider them as syntypes as both agree with the primary description. SPAETH (1931a) synonymized Omocerus bolivianus with O. reichei Boheman, 1850 assuming that the later is rather variable species and O. bolivianus is only its form.

BOHEMAN (1850) used at least three specimens for description of O. reichei as he mentioned three type localities. BOROWIEC (1999a) designated lectotype from the only specimen retained by Boheman from Colombia. I have compared this lectotype to syntypes of O. bolivianus and in my opinion the two taxa are distinct. Omocerus bolivianus has distinctly coarser punctate elytra and punctures with deeper fovea, the postscutellar hump is more prominent and wider, laterally with deeper impressions, and longer humeral projections than O. reichei . Due to the coarser and deeper punctation the elytra of O. bolivianus appears less regular while O. reichei has elytra smooth and surface between punctures regular and smooth. Therefore I restore the species status of O. bolivianus .

Distribution. Bolivia: Santa Cruz ( BOHEMAN 1850; BOROWIEC 1996, 2009c).
