Austroearinus Sharkey 2006, n. gen.
No full textAustroearinus Sharkey n. gen. (Fig. 1b) Diagnosis Austroearinus can be distinguished from all other agathidine genera with the following combination of characters: tarsal claws with a basal tooth; mesoscutum unsculptured and lacking notauli; hind coxal cavities open; propleuron without projection; ovipositor as long as or longer than metasoma. Description Head: Carinae on frons lacking; interantennal space lacking two prominences separated by shallow groove; gena not extended ventroposteriorly into sharp prominence; labial palp with four segments, third segment not reduced; apical antennomere acute; antennal insertion bordered anteriorly, medially, and laterally by moderately elevated ridge. Mesosoma: Mesoscutum smooth; notauli lacking; posteroscutellar depression absent; median areola of metanotum well defined with sharp carinae laterally and posteriorly; propodeum from completely smooth to carinate with anterior transverse carina and with pair of longitudinal carinae enclosing large medial cell; propleuron mildly convex to flat lacking ventromedial prominence; propodeal pseudosternite poorly developed and not separating hind coxal cavities from metasomal foramen. Legs: Foretibia lacking pegs; foretarsal claws with quadrate basal lobe; basal lobe with tuft of pectination basally (c.f. Fig. 2c); midtibia with apical and medial pegs; hind tibia with apical pegs. Wings: RS + M vein incomplete and not tubular throughout, though often more complete than most genera of Agathidinae (Fig.1b); second submarginal cell triangular to weakly quadrate; 3RSb straight; hind wing r and rm crossveins absent; CUb sometimes present as a nebulous or spectral vein. Metasoma: Median tergites smooth lacking sculpture; median tergite 1 with pair of longitudinal carinae diverging distally; median syntergite 2 + 3 with 1 or 2 transverse depressions, distinct grooves absent; ovipositor mildly decurved, longer than metasoma (slightly shorter than the metasoma in one species) usually as long as body. Type species Bassus rufofemoratus (Muesebeck) (Fig. 1b). Distribution New World, primarily Neotropical. One species, Austroearinus rufofemoratus n. comb., is widespread in central and eastern USA and through Central America, but the genus is far more diverse in warm tropical areas. Species diversity At least two species formerly placed in other agathidine genera belong here: Austroearinus rufofemoratus, originally placed in Bassus (Muesebeck 1927), and subsequently transferred to Earinus (Sharkey 2004); Austroearinus unicolor (Schrottkey) n. comb., originally placed in Orgilus (Schrottkey 1902), but more recently considered as a member of the genus Bassus. The genus is extremely species rich. I estimate there to be more than 100 species and perhaps several times this number. Many species also appear to be common, for example, there has been intensive Malaise trap sampling in La Selva, Costa Rica for more than a decade (http://viceroy.eeb.uconn.edu/ALAS/ALAS.html) and, of all species of Agathidinae, A. chrysokeras has been the most frequently collected. Biology (Dan Janzen, pers. comm.) A specimen of A. rufofemoratus from Guanacaste Province, Costa Rica, was reared from a microlepidopteran, only identified as Tortricidae, feeding on the mature leaves of Amyris pinnata (Rutaceae) and living in a light silk web. The wasp larva emerged from the last instar caterpillar on 6 April 2002 and spun a strong white cocoon tightly glued to the leaf surface. This is unlike other known agathidines which spin inside the caterpillar cocoon. The wasp eclosed 9 days later, which means that all of this happened in the full dry season. The site is 280 m elevation, Lat 11.04562 Long 85.45742, and locally known as Puente Mena in the Del Oro property adjacent to the north boundary of the Area de Conservacion Guanacaste. The site lies on the interface between ACG dry forests and ACG rain forest. The entire record may be found at http://janzen.sas.upenn.edu, refer to specimen number 02SRNP14223. Etymology From the Latin australis which means southern, referring to the southern distribution of this genus and its morphological similarity to Earinus.Published as part of Sharkey, Michael, 2006, Two new genera of Agathidinae (Hymenoptera: Braconidae) with a key to the genera of the New World, pp. 37-51 in Zootaxa 1185 on pages 45-46, DOI: 10.5281/zenodo.264601

Pneumagathis Sharkey
No full textPneumagathis Sharkey NEW GENUS (Fig. 5) Type species. Pneumagathis spiracularis (Muesebeck) NEW COMBINATION. Original combination = Bassus spiracularis Muesebeck (1927). Diagnosis. Propodeal spiracle elongate (Fig. 5); first median tergite mostly smooth with two longitudinal carinae; frons not margined by carinae; tarsal claws simple with a large basal lobe. The only other agathidines with elongate propodeal spiracles belong to the Disophrini and these have cleft claws. Description. Head. Lateral carina on frons (as in members of Alabagrus) absent; interantennal space with a raised triangular prominence; gena not extended ventroposteriorly into sharp prominence; gena lacking sharp angle posterad eye; mandible dorsoventrally flattened; labial palpus with 4 segments, third segment reduced, less than ½ length of apical segment. Mesosoma. Propleuron weakly convex ventrally and lacking a sharp bump; notauli impressed, with or without pits or crenulae; posteroscutellar depression absent but sculpture usually present in this area; propodeum areolate rugose, usually with pair of longitudinal carinae and a transverse carina that define distinct areolae; propodeal spiracle large and elongate, more than twice as long as wide; sclerite between hind coxal cavities and metasomal foramen narrow but complete, its ventral margin situated ventral to dorsal margin of hind coxal cavities. Legs. Fore tibia lacking dull pegs; mid and hind tibia with blunt apical or preapical pegs; all tarsal claws with basal lobe. Wings. Fore wing RS+M vein mostly absent; second submarginal cell triangular and petiolate; fore wing 3 RSb straight and strong throughout; hind wing r and r-m cross veins absent; hind wing vein CUb tubular as a short stub, or lacking tubular stub, with a long pigmented non-tubular extension; wings strongly infuscated. Metasoma. First median tergite longer than wide apically, with or without weak rugose sculpture and always with pair of longitudinal carinae; second and third median tergites smooth; second tergite with a strong curved transverse depression; ovipositor about as long as metasoma, slightly thickened preapically. Diversity and Distribution. There are two described species, Pneumagathis spiracularis (Muesebeck) and P. brooksi (Sharkey ) new combination (original combination = Bassus brooksi Sharkey (in Janzen et al. 1998)) and perhaps a few more undescribed species. The genus is widespread and rather common over most of the contiguous states of the US, south through the dryer regions of Costa Rica. Biology. Parasitoids of skippers (Hesperiidae), P. spiracularis has 4 published hosts Cogia outis, Gesta gesta, Erynnis zarucco, Systasea pulverulenta (Marsh et al. 1979) and Pneumagathis brooksi new combination parasitizes 24 known species of pyrgine hesperids (Janzen et al. 1998). Janzen et al. (1998) discuss other aspects of the life-history of P. brooksi. Etymology. From the Greek agathis, meaning “ball of thread”, and the Greek pneuma, meaning “breath”. The latter word is a reference to the elongate propodeal spiracle (Fig. 5 D). The gender is feminine. Molecular data.
