Centris (Hemisiella) fulviventris Cresson, 1865 nom. rev.

Centris fulviventris Cresson, 1865 . 193, 194.

Type data: This species was described based on a single female specimen collected in an undetermined locality in Cuba, Greater Antilles. The holotype is currently deposited at the Gundlach collection in the IESH and has the following data label: [light brown label with black margins] Centris fulviventris . [handwritten] [yellowish brown label glued on the former label] 168 [printed]\ [square light brown label with black margins] Cr [handwritten].

Type locality: Greater Antilles: Cuba .

Centris simillima Smith, 1874 . 370 N ew junior synonymy

Type data: This species was described based on an undetermined number of females collected in the Dominican Republic, Greater Antilles. In the NHMUK a female was found belonging to the type series, which is here designated the lectotype. The specimen has the following data label: Type H. T. [red-rimmed circular label, printed]\ B.M. TYPE HYM. [printed] 17B.918. [handwritten]\ St. Dom. 55,1. [printed]\ Centris simillima Smith (Type) [handwritten]. The lectotype is in good condition and is coded NHMUK 010812612 in the NHMUK data portal.

Type locality: Dominican Republic: Santo Domingo (“San Domingo”) .

Comment: The synonymy of this species with C. lanipes (Fabricius, 1775) was originally proposed by Friese (1901) and subsequently accepted by other researchers (see, for example, Moure et al., 2007). The lectotype of this latter species is housed at ZMUC and its examination revealed that is actually a different species from C. fulviventris . The primary type of this species was not examined during the last century and its study revealed that is conspecific with C. simillima, a species also proposed as junior synonym of C. lanipes (Ducke, 1910) . As a result of the critical study of the type specimens of all these species, C. fulviventris and C. simillima are withdrawn from the synonymy of C. lanipes, proposing the revalidation of the former species and the latter species as its new junior synonym.
