23. Trigona apicalis Smith, 1857 Fig. 24 Trigona apicalis Smith, 1857: 51, ♀. Type material examined Lectotype MALAYSIA • ♀; Sar. [Sarawak]; [29 Oct. 1854 – 10 Feb. 1856]; OUMNH, ENT-HYME2782-01. Paralectotype MALAYSIA • 1 ♀; Sar. [Sarawak]; [29 Oct. 1854 – 10 Feb. 1856]; OUMNH, ENT-HYME2782-02. Other material examined MALAYSIA • 1 ♀; Sark./Mouhot; OUMNH (of no type status). Type locality Borneo (Sarawak). Notes This species was not dealt with by Baker (1993). Rasmussen (2008: 51) indicates that the holotype is in the OUMNH collection, but we found three specimens standing in the type collection. Two bear typical Wallace labels indicating collection in Sarawak, and the third has a printed label, suggesting that it is not syntypic. The specimen bearing both a white disc and a determination label of Trigona apicalis written in Smith’s hand is hereby designated as the lectotype. Current status Tetrigona apicalis (Smith, 1857) (Rasmussen 2008). Distribution Myanmar, Cambodia, Thailand, Malaysia (Peninsula, Borneo), Singapore, Indonesia (Kalimantan) (Rasmussen 2008; Ascher et al. 2022).
