| Resumo: | Trissolcus adrianae Costa & Johnson, sp. nov. is described. It is an egg parasitoid of the neotropical bark bug Phloea subquadrata Spinola (Hemiptera, Phloeidae) on Plinia cauliflora (Mart.) Kausel (Myrtales, Myrtaceae). Trissolcus adrianae belongs to the flavipes species group and can easily be distinguished from other flavipes group members by its noticeably depressed habitus; head oblong in anterior view; bidentate mandibles; frontal depression delimited dorsally by carina; orbital furrow sculptured, constricted through most of its length by lateral expansion of frons; notauli absent; and the length of T3–T6 subequal to the length of T2. This is the first species of Scelionidae associated with the family Phloeidae (Hemiptera: Pentatomoidea) and the first report of parasitism of Phloeidae eggs as well. |
| Descrição: | Trissolcus Ashmead (Hymenoptera, Scelionidae) is a cosmopolitan genus comprising ca. 150 described species (Johnson 1992). Trissolcus species are egg parasitoids of Pentatomoidea (Hemiptera, Heteroptera). The genus is divided into five species groups (Kozlov and Kononova 1983). The flavipes group is particularly abundant in the Neotropical Region (Johnson 1984a, 1987) and is characterized by the presence of a hyperoccipital carina; frons with large setigerous punctures at least laterally; frons strongly bulging between antennal insertions and inner orbits; orbital furrow usually strongly expanded ventrally; antenna with radicle concolorous or lighter than the scape; gena rounded from malar sulcus to occipital carina, with no carina extending from base of mandibles dorsad; notauli well-developed; and sublateral setae on T1 usually absent (Johnson 1984a). In addition, Talamas et al. (2015) recently added that the clypeus in this group has 4 or fewer setae. |
