Xylocopa (Neoxylocopa) rufidorsum Enderlein, 1913: 160 (Lectotype: USNM; ♀, Peru, Chanchamayo) (new lectotype designation).

Diagnosis.

This species can be recognized by the combination of the following features: medium body size (body length, ~21 mm); pubescence black, except dorsum of mesosoma densely covered with ferruginous setae; integument dark brown to black throughout, except tegula reddish brown; wings dark brown with strong violet highlights; labrum basally with three longitudinally enlongated tubercles; gena and supraocular areas sparsely punctate; mesoscutellum with subhorizontal dorsal surface smooth and shiny, declivitous posterior surface weakly imbricate, dull, not separated by a border or carina; T2 densely punctate on disc, punctures separated by 1-1.5 times a puncture width, punctures denser laterally; T3 sparsely punctate on disc, punctures separated by 2-3 times or more a puncture width; T1 with plumose and very short, simple setae intermixed; discs of T2 and T3 with very short (0.2-0.7 × OD), simple setae, increasing in length laterally and on apical terga; T4 and T5 with long (1.0-1.5 × OD), simple setae.

Comments.

As indicated by Moure (1949), X. rufidorsum belongs to the group of species that includes X. similis Smith, X. tacanensis Moure, X. eximia Perez, and X. aurulenta (Fabricius), which share the ferruginous pubescence on the dorsum of mesosoma. Xylocopa similis can be easily recognized by the presence of ferruginous setae on T1 (T1 with black setae in X. rufidorsum ); X. aurulenta by the wings light brown with coppery highlights (dark brown with strong violet highlights in X. rufidorsum ); X. eximia by the presence of long (≥1.5 × OD), simple setae on discs of T2 and T3 (discs of T2 and T3 with short [0.2-0.7 × OD], simple setae in X. rufidorsum ); and X. tacanensis by the gena and T3 more densely punctate, punctures separated by 1-1.5 a puncture width (at least 2 or 3 times a puncture width in X. rufidorsum ).

Xylocopa rufidorsum was described from three females and no holotype was designated. As in the case of X. andica and X. mendozana , these syntypes were also loaned to the late J.S. Moure and have never returned to the MIZ (T. Hufleit, pers. comm.). We only found one of these females in the general bee collection of the USNM; the remaining two females could not be located at the Universidade Federal do Paraná, Curitiba, Brazil (G. Melo, pers. comm.). To stabilize the name, we chose the female we found as the lectotype. The label data for this specimen are as follows: Peru, Chanchamayo [Wilhelm] Hoffmanns [green label] / Co=Typus [yellow label] / Xylocopa rufidorsum Enderl. ♀ Type Dr. Enderlein det.1913 [handwritten] / Mus. Zool. Polonicum. Warszowa. 12/45 / Lectotype, Xylocopa rufidorsum Enderlein des. M. Lucia & V.H. Gonzalez. This specimen is currently deposited in USNM.
