A remarkable new species of Zethus Fabricius (Hymenoptera, Vespidae, Eumeninae) from Costa Rica
(2008)
Porter, new species, is described from Costa Rica. It forms a species group of its own, unique in its grotesquely enlarged male mandibles and reduced clypeus, single mid tibial spur, and in having a medio-apical bulge on the second sternite. It was previously identified as Z. magretti Zavattari but reexamination of the type of this species shows that it actually belongs to the coeruleopennis species group.
Therion Curtis (Ichneumonidae: Anomalinae) has a nearly cosmopolitan geographic distribution but has not previously been recorded from South America. In most Therion the tarsal claws are simple or have only a few inconspicuous teeth near the base. The new species described herein are distinctive, therefore, because they have the tarsal claws conspicuously pectinate over at least 0.8 the distance from base to apex. Therion ranti n.sp. from Cordoba and Mendoza Provinces of Argentina may be recognized by its almost uniformly red mesosoma and basally elevated clypeus. In Therion wileyi n.sp., from the Andean puna near La Paz in Bolivia, the mesosoma is red with extensive black coloration, including much of the propodeum, and the clypeus is weakly and symmetrically convex in profile. Therion wileyi n.sp. was reared from an unidentified noctuid moth larva infesting Chenopodium quinoa (Angiospermae: Chenopodiaceae), an importantfood crop in Andean South America.
Labium is a primitive transantarctic genus which parasitizes ground-nesting halictid bees and until now has been known only from the Australian Region. Diagnostic features include its large exposed labrum (as long as clypeus) ; elongate mandible with upper tooth much shorter and smaller than lower tooth; slender 1st gastric tergite with spiracle distad of middle; and short, concealed ovipositor which is slender, depressed, and without notch or nodus. Labium wahli is now described from south Brazilian rain forest. It differs from the Australian species by its longer flagellum which is only slightly thickened apicad and because it has no crests at base of the notauli
Acrotaphus fuscipennis (Cresson), distinctive because of its black wings and bright red body, is recorded for the first time from the United States. It was reared from araneid spiders collected in Florida, which constitutes the first host record for this species. Acrotaphus tibialis (Cameron), collected in Texas, is also recorded for the first time in the United States. New U.S. localities are given for A. wiltii (Cresson). A key is provided for the identification of the three species of Acrotaphus in United States. The adults of all three species and the cocoon of Acrotaphus fuscipennis are illustrated.
