Notocyrtus gibbus (Fabricius, 1803)

( Figs. 17-19 )

Material examined. Notocyrtus gibbus . COSTA RICA. 1 male: [handwritten torn label:] Costa Rica / Farm Hamburg a. Reventazon / bei S. Jose...1924 [?] / F. Nevermann leg. [white framed printed label:] ZMH 849006; 1 female: [printed pale brownish label:] Farm Hamburg am / Reventazón. / 12-30 km v. Atlantik / [handwritten]: 14.10. [printed:] 1926 // [printed pale green label:] F. Nevermann leg. / Eng. Nr. 99.192 6 [white framed printed label:] ZMH 849007 [ ZMH]. Notocyrtus Burmeister, 1835 currently includes 24 valid species, all of which considered as mimetic of meliponine bees ( Haviland 1931; Jackson 1973; Gil-Santana 2008). Subsequent papers with descriptions of species or other information posterior to the revisions of Carvalho and Costa (1992, 1993) of the genus, were listed by Gil-Santana (2022). Notocyrtus gibbus (Fabricius, 1803) had already been recorded from Bolivia, Brazil, French Guiana, Guyana and Paraguay ( Stål 1872; Lethierry and Severin 1896; Haviland 1931; Carvalho and Costa 1993; Gil-Santana 2008). The male ( Figs. 17-18 ) and the female ( Fig. 19 ) from Costa Rica agree well with the redescription provided by Carvalho and Costa (1993), except by the sternites. While in the examined specimens the sternites are completely pale ( Fig. 18 ), Carvalho and Costa (1993) described the abdomen as black with the posterior portion of segments II to IV pale. We consider this as a color variation of the species, as commonly recorded in other species of Harpactorinae (e.g., Gil-Santana 2022), including Notocyrtus spp. , in which the variation in color was hypothesized as being a result of mimicking different meliponine bees in different localities ( Jackson 1973).

Distribution. Bolivia, Brazil, Costa Rica (new record), French Guiana, Guyana, Paraguay.
