Dicerataspis grenadensis Ashmead, 1896

( Figs. 16–23 View FIGURES 16 – 23 )

Dicerataspis grenadensis Ashmead, 1896: 744 .

Diagnosis. Body stout. Head ( Fig. 16 View FIGURES 16 – 23 ) with lateral margin of occiput not well defined. Eyes without pubescence. Face ( Fig. 16 View FIGURES 16 – 23 ) with a prominent median area bounded laterally by grooves. Antennae of female ( Fig. 17 View FIGURES 16 – 23 ) pilose, cilindrical, widened towards apex, club 6 ­segmented, conspicuous. Antennae of male ( Fig. 18 View FIGURES 16 – 23 ) with the first flagellomere slightly curved, distally swollen, longer than second. Dorsal margin of pronotal plate ( Fig. 19 View FIGURES 16 – 23 ) with three emarginations; sides of pronotum smooth. Mesoscutum ( Figs. 20 and 21 View FIGURES 16 – 23 ) convex in profile, smooth. Dorsal part of scutellum ( Fig. 21 View FIGURES 16 – 23 ) areolate­rugose; dorsoposterior part in dorsal view emarginate, with two small lateral angles and conspicuous posterior angles. Scutellar plate ( Figs. 20 and 21 View FIGURES 16 – 23 ) small, elevated, with a circular pit close to the posterior margin of the plate. Mesopleuron ( Fig. 20 View FIGURES 16 – 23 ) with subalar pit. Metapleuron ( Fig. 20 View FIGURES 16 – 23 ) slightly sculptured. Forewings ( Fig. 22 View FIGURES 16 – 23 ) completely hyaline or dusky at base, pubescent, apical margin with hair fringe; marginal cell anteriorly open; veins pale. Metacoxa ( Fig. 23 View FIGURES 16 – 23 ) with a band of hairs along the posterior margin. Third abdominal tergum of metasoma ( Fig. 20 View FIGURES 16 – 23 ) with a thin hairy ring at base; metasoma distally smooth.

Note: The coloration and size of the specimens of D. grenadensis collected in Brazil vary without correlation with biogeographical factors.

Geographical distribution. Neotropical Region: Grenada ( Ashmead 1896); Argentina ( Diaz 1974) and Brazil (new country record), in the State of São Paulo.

Hosts. Wharton et al. (1998) pointed out that the small size of Dicerataspis specimens make them probable parasitoids of drosophilids.

Remarks. Dicerataspis was described by Ashmead (1896) based on one species, Dicerataspis grenadensis from Grenada. Kieffer (1909) described the genus Dissodontaspis , monotypic on Dissodontaspis flavipes from Brazil. Weld (1921) suggested that Dissodontaspis could be a synonym of Dicerataspis . Later, Weld (1952) established the generic synonymy and the current combination, Dicerataspis flavipes .

Type material. Dicerataspis grenadensis : GRENADA. (Mount Gay Est.), Holotype, (1 female), coll. Smith. ( USNM). Dicerataspis flavipes : BRAZIL. Pará: Holotype, (1 female), coll. Baker ( CASC).

Material collected. BRAZIL: São Paulo: Nazaré Paulista, (2 males), 11.VII. 1996; (1 female), 19.VII. 1996; (13 males), 19.VII. 1997; Monte Alegre do Sul, (1 female); 24.IV. 2000; Campinas, (1 male); 30.XI. 1994, (1 male, 1 female); 7.II. 96, (3 males); 9.III. 2000, coll. M.F. Souza Filho; Piracicaba, (3 males, 5 females), 14.III. 2000, coll. J.A. Guimarães. ( ESALQ).

The specimens from Brazil, state of São Paulo, Nazaré Paulista (19.VII. 1996 and 11.VII. 96) and Campinas (30.XI. 94 and 7.II. 1996) had been misidentified as D. flavipes by Guimarães (1998) and Guimarães et al. (1999, 2000 a; 2000 b).
