Charterginus nevermanni Bequaert, 1938 , Rev. Entomol., Rio de Janeiro 9: 99, fig.1, pl. 3, female, nest (in subgenus Hypochartergus ) - “ Costa Rica: 20 kilom. North of Siquirres and about 12 kilom. from the Atlantic Ocean” (Eberswalde); also from Suretka; and Honduras; Panama — Richards, 1978, Soc. Wasps Am.: 128 (key), 129—West-Eberhard et al., 1995, Hym. Costa Rica: 586 ( Costa Rica)— Kojima and Carpenter, 1998, Entomol. Sci. 1: 420, figs. 20-21 (morphology)— Andena et al., 2009, Journal of Natural History. 43: 1183-1193 (phylogeny, key).

Diagnosis. Length 8.0– 8.5 mm., length fore wing 8.0 mm.

Blackish species, with yellow marks on the lateral gena, humeral margin of pronotum, metanotum; blackish wings. Macropunctures on frons, vertex and mesosoma dense, coarse; metasomal tergum I with shallow pits; metasomal tergum II with well-marked but sparse punctation. Clypeus longer than wide, apex truncate; gena narrow, less than half width of eyes; occiput without angular projection; occipital carina dorsal only, projecting; humeri rounded; tegula more than three times as long as wide, posterior margin obliquely rounded; metanotum compressed; metanotal tubercle absent; propodeal orifice with sides converging, almost pointed dorsally; metasomal tergum I petiolate, transversely widened posteriorly, with a distinct preapical transverse carina; tergum II with a distinct apico-discal prominence.

Comments. Richards (1978) says: “the Holotype from a nest in Costa Rica; other specimens also from Honduras and Panama. The MNH has two of Bequaert’s paratypes. The nest was snow-white, brittle, with 7.0 mm stalk and the envelope 5.0 cm diameter and 2.2 cm high. It was approximately circular. Here we examined an NHM paratype and additional material from Costa Rica and Panama from the AMNH. Charterginus nevermanni inspected a Cecropia obtusifolia trichilium for food bodies in Costa Rica (LaPierre et al. 2007).

Type material examined: Paratype ♀: COSTA RICA: Hamburg Farin, M.C.Z . Paratype [label], Charterginus nevermanni ♀ J.B. [label], NHMUK 010817939 ( NHM) .

Additional material examined: COSTA RICA: Suretka Province , Limon, 31.v.1924, J.C. Bradley (col.) (♀ AMNH) ; Herendia, Pr. La Selva Biol. Sta., 3 Km S Pto. Viejo, 10º26’N 84º01’W, 9.vii.1993, Hespenheide H.A. (col.) (2♀ AMNH) ; PANAMA: Bocas del Toro, Changuinola Distr. , 02.v.1924, J.C. Bradley (col.) (♀ AMNH) .

Distribution ( Fig. 8 ): Honduras; Costa Rica; Panama.
