Bees of the genus Lasioglossum (Hymenoptera: Halictidae) from Greater Puerto Rico, West Indies Gibbs, Jason European Journal of Taxonomy 2018 2018-02-01 400 1 57 Gibbs, 2018 Gibbs 2018 [544,945,267,294] Insecta Halictidae Lasioglossum GBIF Animalia Hymenoptera 16 17 Arthropoda species enatum sp. nov. Dialictus   Figs 4D, 9–11    Diagnosis Both sexes of  Lasioglossum enatum sp. nov.can be recognized by tegula punctate, extended posteriorly to form small angle, mesepisternum punctate and metasoma brown. The shape of the tegula distinguishes it from all other species of L. (  Dialictus) from Puerto Rico, except  L. monense sp. nov.on Mona Island. The female of  L. monense sp. nov.has a pale metasoma and obscure punctation on the supraclypeal area. The male of  L. enatum sp. nov.has the mesoscutum and mesepisternum more polished and shiny than in males of  L. monense sp. nov.Other members of the  L. parvumspecies complex, to which it belongs, share this character. In the female, the complete absence of punctures on the apical impressed margins distinguishes  L. enatum sp. nov.from  L. parvumand  L. busckiellum, which both have minute setose punctures in this area. In the male, the appressed sternal setae and dark tarsi distinguish  L. enatum sp. nov.from  L. parvum, which has sternal setae erect and tarsi pale.    Etymology The specific epithet  enatumis a participle of the Latin enascor, meaning having sprouted or sprung forth.    Material examined  Holotype   PUERTO RICO: ♀, Cabo Rojo, Boqueron, 17°58.994′ N, 67°08.455′ W, Field House, ground bee bowl,  12–16 May 2014, S.G.

Metasomal terga with apical impressed areas medially less than ⅓ length of basal area. T2–T3 depressed anteriorly. TERMINALIA. As illustrated in Fig. 4D.    Distribution  Puerto Rico( Fig. 11), British and U.S. Virgin Islands.    Biology   Lasioglossum enatum sp. nov.has been recorded visiting the following flowers: Gundlachia corymbosa(Urb.)
