Type data

Cockerell (1912a) described this species from a single male specimen currently housed at AMNH. The holotype, as well as the primary types of C. heterodonta and C. libertatis (see below), were collected during the Stanford Expedition to Brazil between the mouth of the Amazon River and Rio Grande do Norte. The journey was coordinated by the American geologist and botanist John Casper Branner (1850– 1922) and had as members, among others, Fred Baker (1854–1938), a malacologist of the San Diego Society of Natural History, and the student of zoology William Mann (1886–1960). Both Baker and Mann assisted in the work of the field trip ( Oliveira 2014). According to Oliveira (2014), the researchers collected species on the coast and backlands of Ceará and Rio Grande do Norte States, as well as along the Madeira River, having spent a few months at the facilities of the Madeira-Mamoré Railway. The holotype has the following data label: Rio Madeira Brazil Mann & Baker [printed]\ Madeira-Mamore R.R. Co. Camp 43 [printed]\ Centris bakeri Ckll. Type. [handwritten]\ AMNH _IZC 00323432 [data matrix code] [printed].

Comments

The study of the type of Centris bakeri revealed that it corresponds to a male of C. varia with two yellow spots on the lateral surfaces of the second tergum. The coloration of the metasoma in both sexes of this species is very variable. Terga and sterna of specimens can be blackish, reddish brown or orange, with or without dark brown or yellowish spots or bands. Centris varia is one of the most widely distributed species of the subgenus C. ( Centris ). According to Moure et al. (2007), it occurs from Mexico to Argentina.
