Habronyx Foerster (Hymenoptera: Ichneumonidae: Anomaloninae) in Andean and Neantarctic South Americawith description of new species from Bolivia and Chile (2007)

Charles C. Porter

Habronyx Foerster occurs in all regions except the Afrotropical and parasitizes lepidopterous larvae (Geometridae, Noctuidae, Saturniidae, Sphingidae, Psychidae). Habronyx albifrons (Spinola) inhabits neantartic Chile and southern Argentina. It is black with a white flagellar annulus and with a strong prepectal carina on the lower half of the mesopleuron. Habronyx albifrons is redescribed and descriptions are given of two new species which belong to a group of their own: Habronyx citrinus Porter, n. sp., from central Chile; and Habronyx punensis Porter, n. sp., from the high Andean steppe of Bolivia, where it attacks noctuid larvae on Chenopodium quinoa Willd. These differ from H. albifrons because the prepectal carina is absent on the mesopleuron, being developed only on the mesosternum, and because they have the flagellum uniformly black and the gaster extensively orange. Habronyx punensis differs from H. citrinus in having a sharp carina on the front, the mesopleural punctures not reticulately confluent, the discoidella weaker and in part desclerotized

A remarkable new species of Zethus Fabricius (Hymenoptera, Vespidae, Eumeninae) from Costa Rica (2008)

Charles C. Porter

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.

New Trachysphyrus Haliday (Hymenoptera, Ichneumonidae) in the albomarginatus species group from northwestern Argentina (2008)

Charles C. Porter

Three new species of the albomarginatus species group of the genus Trachysphyrus (T. fidalgoi, T. riojanus, and T. tmetus) are described from the Subandean Desert (Monte) of Northwest Argentina. A key is given to these and to the five described species also known from Neotropic Argentina in the semiarid Prepuna, Subandino, and Chaco Serrano as well as in such wetter habitats as the Chaco Húmedo and Selva Tucumano-Boliviana (Yungas). Four additional species occur in Neantarctic Chile from Santiago south to Magallanes with overlap into the Nothofagus forests of southwest Argentina (Neuquén, Río Negro). Several species have been reared from cocoons of Lepidoptera (Megalopygidae, Psychidae) and others from mud nests of eumenid wasps (Hypodynerus Saussure, Pachymenes Saussure).

New Phycitiplex Porter (Hymenoptera, Ichneumonidae) from Subandean Desert in northwest Argentina (2008)

Charles C. Porter

Six new species of Phycitiplex (P. obscurior, P. tricinctus, P. unicinctus, P. peralta, P. trichroma, and P. lepidus) are described from material taken by Malaise trap in a humid ravine at Santa Vera Cruz in the Subandean Desert (Monte) of La Rioja Province (Argentina). These are keyed along with several closely related described species. Except for P. eremnus from central Chile, this genus is known only from the semiarid Chaco and Subandean biogeographic provinces in the northern half of Argentina. The only available host record is of Phycitiplex doddi (Cushman) reared from larvae of Cactoblastis cactorum (Berg), a phycitid moth that attacks prickly pear cacti.

First neotropic record of Idiolispa with description of a new species from Honduras (Hymenoptera: Ichneumonidae) (1993)

Charles C. Porter

Idiolispa Foerster (Ichneumonidae: Phygadeuontinae: Mesostenini) has been known previously only from the Holarctic Region but an undescribed species now is reported in tropical cloud forest (1800 m) on Monte Uyuca near the Escuela Agricola Panamericana at Zamorano, Honduras.

First notice of Therion from South America with description of two new species from Argentina and Bolivia (Hymenoptera: Ichneumonidae) (1999)

Charles C. Porter

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.

New species and records of Rhyssa and Rhyssella (Hymenoptera: Ichneumonidae: Rhyssinae) from Florida and Central America (2001)

Charles C. Porter

Rhyssa neotropicae n. sp. is the first Rhyssa to be recorded from the New World tropics, where it was collected in cloud forest at 1800 m on Monte Uyuca near Zamorano, Honduras. It is closely related to the Nearctic R. hoferi Rohwer and R. howdenorum Townes but differs from all other Rhyssa by its complexly yellow and black marked head and body, whose color pattern mimics that of aggressive social vespid wasps (Agelaia) which occur in the same habitat. Rhyssa howdenorum Townes is recorded for the first time from Florida and Oklahoma. The genus Rhyssella, previously unknown in Florida, is represented in that state by R. perfulua n. sp., distinctive in its mostly orange brown coloration, and by R. humida (Say), a black and white species with fulvous on the thoracic pleura and propodeum.

First records of the Neotropic genus Dilopharius Townes (Hymenoptera: Ichneumonidae: Ichneumoninae) in Florida (2001)

Charles C. Porter

Dilopharius Townes (1966) ranges from the southern United States to Argentina. Its only described species is D. otomitus (Cresson 1868), previously known from Mexico and south Texas, but now recorded for the first time from Florida.
