%0 Journal Article %T Hyperparasitoid wasps (Hymenoptera, Trigonalidae) reared from dry forest and rain forest caterpillars of Area de Conservaci¨Žn Guanacaste, Costa Rica %A David Smith %A Daniel Janzen %A Winnie Hallwachs %A Alex Smith %J Journal of Hymenoptera Research %D 2012 %I Pensoft Publishers %R 10.3897/jhr.29.3233 %X 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 Conservaci¨Žn 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. %K Central America %K hyperparasitoid host specificity %K Lepidoptera %K Diptera %K DNA barcoding %K tropical trophic web %U http://www.pensoft.net/journals/jhr/article/3233/
