The type material of Melipona postica Latreille, the type species of the stingless bee genus Scaptotrigona Moure (Hymenoptera, Apidae)

The present contribution deals with the recognition of the type material of Melipona postica Latreille and the identity of the taxon it represents. The origin of the specimens studied by Illiger and Klug, and which Illiger later sent to Latreille, is traced to Francisco Agostinho Gomes, who collected the material in Salvador, Bahia, and sent them to the Count von Hoffmansegg, in Prussia. Based on material located at the Museum für Naturkunde, in Berlin, a lectotype is designated for Melipona postica Latreille. The specimen is redescribed and illustrated. The name Scaptotrigona xanthotricha Moure is placed as a synonym of S. postica.

Figure 1
Photographs of manuscript lists compiled by Illiger (or perhaps Hoffmansegg) of taxon names based on the specimens received from shipments sent by Francisco Agostinho Gomes (documents filed under “Gomes, Franz August” in the Historische Bild- und Schriftgutsammlungen of the Museum für Naturkunde, in Berlin). A. Top section of front page of sheet 89; the heading reads “Gomes’ first shipment from Spring 1801 contained” (in the original “Gomes erster Transport vom frühjahre 1801, enthielt”). B. Upper half of front page of sheet 90 containing a list of insects. The taxa considered as undescribed species are indicated by an asterisk and are followed by “N.”, an abbreviation of “Nobis”, meaning “to us” (as a new species). The right column gives names of bees, all placed in the genus Apis; the name “Apis postica” is highlighted.
