Centris (Hemisiella) fulviventris Cresson, 1865

Centris fulviventris CRESSON, 1865 . 4:193, 194.

Type data. Cresson described this species based on a single female collected in Cuba. The holotype is housed at IESH and has the following data label: [light brown label with black rim] Centris fulviventris . [handwritten] 168 [printed]\ [squared label with black rim] Cr [handwritten] ( IESH) .

Type locality. Greater Antilles : Cuba .

Comments. The type specimen, as well of those of C. cornuta and C. armillata belong to the Gundlach collection. Johannes Christoph Gundlach (1810–1896) was a German- Cuban naturalist and taxonomist. In 1839, he left Europe to make collections on the Caribbean island of Cuba, where he lived ever since ( VILARÓ, 1897). In 1875, he changed his name from Johannes Christoph to its Spanish equivalent Juan Cristóbal. He wrote the first major work on the birds ( GUNDLACH, 1876), reptiles ( GUNDLACH,1880) and insects of Cuba ( GUNDLACH, 1881, 1886, 1891, 1922). The type locality cannot be further narrowed down than to Cuba. This is the only species of C. (Hemisiella) recorded in that country.

Centris (Hemisiella) montezuma Cresson, 1879 (FIgs 1‒4)

Centris montezuma CRESSON, 1879b .7:213. Junior synonym of C. vittata Lepeletier, 1841 ( SNELLING, 1966).

FIgs 1‒4. Centris montezuma Cresson, 1879 , lectotype male: 1, clypeus and labrum, lateral view; 2, head, frontal view; 3, lower margin of hind tibia; 4, spine-like projection on the posterior margin of hind basitarsus.

Type data. This species was described based on two males collected in an undetermined locality in Mexico. CRESSON (1916) designated the lectotype which is currently housed at ANSP. The specimen has the following data label: Mex. [printed]\ [red label] LectoTYPE [printed] 2625 [handwritten] ( ANSP).

Type locality. Mexico .

Comments. The lectotype was collected by the Swiss ornithologist Francis Sumichrast (1828–1882), the same collector of the type specimens of C. totonaca and C. otomita (see below). The specimen designated the lectotype is relatively large and has the spine-like projection on the posterior margin of the hind basitarsus, present in males of the subgenus C. (Hemisiella), quite developed (Fig. 4). This makes it seem different from C. vittata , since the males of this later species are usually a bit smaller. Both the difference in body size and that of the projection of the hind basitarsus seem to be due only to a matter of scale, since the smaller males have proportionally a reduced projection. This is also found in the spine-like projection of the distal end of the hind tibia (Fig. 3), which is also variable in males of this species.

Both sexes of this species have the pubescence on mesoscutum, mesoscutellum and vertex with black tips and the clypeal disc transversally concave (Figs. 1, 2). Photos of both sexes of this species can be found in VIVALLO & ZANELLA (2012). The type locality of C. montezuma cannot be further narrowed down than to Mexico. This species occurs from Mexico to Paraguay ( MOURE et al. 2007).
