Abstract: Trigonalyidae are rarely collected hyperparasitoids that attack the larvae of Ichneumonoidea, and Tachinidae associated with phytophagous sawfly or Lepidopteran larvae, or primary endoparasitoids of Vespidae larvae. Trigonalyidae mainly occur in tropical and subtropical regions, but recent studies indicate that they are found to be fairly common in mountainous regions. In this study, DNA barcoding methods based on sequences of the COI gene were used to discriminate Trigonalyidae species from Yunnan Province, which is situated in a mountaineous area of southwest China. In total, 25 COI sequences belonging to 14 morphospecies of four genera were obtained. The intraspecific pairwise distances ranged from 0 to 3.3% and the interspecific pairwise distances ranged from 5.3% to 17.3%. The delimitations of all studied species are congruent with the morphological identification results in both ABGD and bPTP methods. Based on both morphological and molecular analyses, four species from Yunnan are described as new: Jezonogonalos eburnalva Zhang & Chen, sp. nov., Lycogaster umbonata Chen & van Achterberg, sp. nov., Taeniogonalos albidorsalis Zhang & Chen, sp. nov., and T. paradoxica Zhang & Chen, sp. nov.

Checklists of the Hymenoptera of Canada, Alaska and Greenland – Introduction https://jhr.pensoft.net/article/60054/ Journal of Hymenoptera Research 82: 1-19

DOI: 10.3897/jhr.82.60054

Authors: Andrew M. R. Bennett

Abstract: The distribution of described, extant species of the insect order Hymenoptera recorded from northern North America will be published in a series of ten checklists. In total, 9250 species in 27 superfamilies and 84 families are recorded from Canada, the state of Alaska (USA) and Greenland (Denmark). Within northern North America, 8933 species are recorded in Canada (96.6% of the total species), Alaska has 1513 (16.4%) and Greenland has 205 (2.2%). Within Canada, Ontario is the province with the most species recorded (5322, 57.5% of all species in northern North America), followed by Quebec (4207, 45.5%) and British Columbia (4063, 43.9%). At the family level, Ontario has 82 of the 84 recorded families, Quebec has 76 and British Columbia has 71. The most species-rich superfamilies in northern North America are Ichneumonoidea (4438 species, 48.0% of the total); Apoidea (1438, 15.5%) and Chalcidoidea (1246, 13.5%). The largest families are Ichneumonidae (3201 species, 34.6% of the total), Braconidae (1237, 13.4%), Tenthredinidae (573, 6.2%), Eulophidae (379, 4.1%) and Pteromalidae (309, 3.3%). Overall species richness of the Hymenoptera in northern North America is compared with surveys in Russia, Germany, Finland and the British Isles.

Trigonalidae (Hymenoptera) of Thailand, other southeastern Asian records, and a new Trigonalys from India https://jhr.pensoft.net/article/4495/ Journal of Hymenoptera Research 44: 1-18

DOI: 10.3897/JHR.44.4495

Authors: David R. Smith, Pierre Tripotin

Abstract: Seven species of Trigonalidae are recorded from Thailand, Lycogaster flavonigrata Chen, Achterberg, He & Xu, L. rufiventris (Magretti), Taeniogonalos fasciata (Strand), T. gestroi (Schulz), T. sauteri Bischoff, T. tricolor Chen, and an unidentified species. Four species, L. flavonigrata, T. cordada Chen, Achterberg, He & Xu, T. sauteri, and T. tricolor are newly recorded from Laos. Diagnoses, illustrations, and distribution records are given for the Thailand species. Trigonalys india Smith, sp. n., is described from southern India for specimens previously misidentified as T. rufiventris.

Hyperparasitoid wasps (Hymenoptera, Trigonalidae) reared from dry forest and rain forest caterpillars of Area de Conservación Guanacaste, Costa Rica https://jhr.pensoft.net/article/1609/ Journal of Hymenoptera Research 29: 119-144

DOI: 10.3897/jhr.29.3233

Authors: David Smith, Daniel Janzen, Winnie Hallwachs, M. Alex Smith

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.
