Abstract: Five species of Trigonalidae, hyperparasitoids of Ichneumonidae (Hymenoptera) and Tachinidae (Diptera) that parasitize caterpillars (Lepidoptera), have been reared during the ongoing caterpillar inventory of Area de Conservación Guanacaste (ACG), Guanacaste Province, northwestern Costa Rica: Lycogaster apicipennis (Cameron), Taeniogonalos woodorum Smith, sp. n., Taeniogonalos fasciatipennis (Cameron), Trigonalys championi Cameron, and Trigonalys maculifrons Sharp. Morphological and DNA barcoding data support species separation of these generalist hyperparasitoids. Taeniogonalos gundlachii (Cresson) is not a widespread, color-variable species as previously treated and is probably confined to eastern North America. The species previously considered as T. gundlachii in Costa Rica is regarded as Taeniogonalos fasciatipennis, a species found only in ACG dry forest. Taeniogonalos woodorum is a similar species but found only in the ACG rain forest. Habitat and host records are given for these five species of trigonalids.

Trigonalidae (Hymenoptera) from cacao agroforestry systems in northeastern Brazil, with two new species of Trigonalys Westwood https://jhr.pensoft.net/article/1592/ Journal of Hymenoptera Research 25: 19-33

DOI: 10.3897/jhr.25.1810

Authors: Bernardo Santos, Alexandre Aguiar, Anazélia Tedesco

Abstract: A survey of Trigonalidae from cacao (Theobroma cacao L.) agroforestry systems in southern Bahia, northeastern Brazil, is conducted. A total of 65 specimens were studied, and three species are recognized. Trigonalys melanoleuca Westwood is diagnosed and illustrated. Two new species are described and illustrated. Trigonalys erythrocephala sp. n. has most of head reddish brown; metasomal armature in sternum III conspicuous, Y-shaped; supra-antennal elevation conspicuous; hind coxa with sharp lateral angles, its dorso-mesal portion strigate; legs entirely dark brown; and fore wing lightly infuscate, darker towards anterior margin. Trigonalys gotica sp. n. with body blackish or dark brown and with pale yellow marks; mesopleuron with an oblique mark; female armature absent; frons and vertex punctate-areolate; supra-antennal elevation subtle; propodeal foramen V-shaped; and fore wing vein M arising distinctly basad to 1cu-a.

DOI: 10.3897/jhr.24.1811

Authors: David Smith, Pierre Tripotin

Abstract: Seven species of the primarily hyperparasitoid family Trigonalidae are reported from Madagascar: Orthogonalys brevis Smith & Tripotin, sp. n., Orthogonalys gigantea Benoit, 1951; O. hova Bischoff, 1933; O. maculata Bischoff, 1933; Orthogonalys parahova Smith & Tripotin, sp. n., O. seyrigi Bischoff, 1933; and Trigonalys natalensis Kriechbaumer, 1894. Diagnoses and a key to species are given.
