Dicerataspis grenadensis

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