Lectotype designations taxonomic notes and new synonymies in some species of the bee genus Centris Fabricius, 1804 described by Frederick Smith (Hymenoptera: Apidae) Author Vivallo, Felipe text Zootaxa 2020 2020-01-29 4729 2 151 176 journal article 24224 10.11646/zootaxa.4729.2.1 3eeb8ad3-f39e-48d6-8b27-0e66d006d322 1175-5326 3632239 A5200288-5C6F-44F9-A0FB-0E479F871A62 Centris ( Paracentris ) aterrima Smith, 1854 Centris aterrima Smith, 1854 . 378. Type data: This species was described based on males collected in an undetermined locality in Mexico . A syntype is housed at NHMUK and 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.902. [handwritten]\ [circular label] 48 13 [handwritten]\ Centris aterrima Smith. Type. [handwritten]\ aterrima Sm. Type [handwritten]. The lectotype is in good condition and is coded BMNH (E) 968165 in the NHMUK data portal. Type locality: Mexico . Centris ( Melanocentris ) anomala Snelling, 1966 . 31. New junior synonymy Type data: This species was described based on a male specimen collected in Guadalajara, Jalisco state , Mexico . The holotype is currently housed at CAS and has the following data label: Mexico : 8 mi. S. Guadalajara, Jal. [printed] late Sept. [handwritten] 1954 F. W. Williams [printed]\ California Academy of Sciences Type No. [printed] 6681 [handwritten]\ [red label] Holo [handwritten] type Centris [printed] anomala ♂ [handwritten] R . R . Snelling [printed]. Type locality: Mexico : Jalisco state : Guadalajara . Comments: The type locality of C . aterrima cannot be further narrowed down than to Mexico . The real identity of this species was unknown for a long time due to the lack of study of its primary type . This confusion increased and it was somehow consolidated with the work of Snelling, who included specimens with this name identified by him in the keys for the species of C . ( Paracentris ) published in 1966, 1974 and 1984 . It is evident that Snelling never saw any primary type of C . aterrima and that he assumed its identity based on the original succinct description made by Smith (1854) . In 1966, Snelling described C . anomala based on specimens of both sexes collected in Mexico . The female has highly modified oil-collecting structures (elaiospathes) which Snelling highlighted by choosing the specific epithet he used for the description of the species. The lack of study of the type specimens of C . aterrima , as well as the lack of alternative keys to that published by Snelling (1966 , 1974 , 1984 ) perpetuated the problem of interpretation of both species. The study of the type material of C . aterrima showed that it corresponds to the male of C . anomala making the latter a junior synonym of C . aterrima . Considering this, it is coherent to assume that some of the references published between 1896 and 1951 cited by Moure et al . (2007) for C . aterrima may be mixed with the Snelling’s misidentified species. All uses of C . aterrima after 1966 belong to other species and those published after the same year using the name C . anomala in fact belong to C . aterrima . The Snelling’s misidentified species correspond to a new species which is described below.
