Aleiodes aquilonius Shaw and Marsh, NEW SPECIES (Figs. 1, 2, 18) Female . Body color : (Fig. 1) head black, occasionally with orange spots behind eyes, antenna dark brown to black, scape often orange at base; mesosoma black except pronotum dorsally, mesonotun and scutellum orange; metasoma black with apex of first tergum, second and third terga entirely, and fourth tergum at base frequently orange; legs orange, coxae sometimes dark brown; wings lightly dusky, veins including stigma brown. Body length : 7.5–8.0 mm; fore wing length, 6.0–7.0 mm. Head : eyes and ocelli small; 49–52 antennomeres, all flagellomeres slightly longer than wide; malar space longer than basal width of mandible and 2 / 3 eye height; temple equal to eye width; occipital carina complete, meeting hypostomal carina; oral space small and circular, width less than length of malar space and about 1 / 2 face height; clypeus swollen; ocelli small, ocellocular distance at least twice diameter of lateral ocellus; face rugose, short median ridge below antennae; frons and vertex rugose; temple coriaceous; maxillary palpus not swollen; mandible small, tips not crossing when closed. Mesosoma : pronotum rugose; mesonotum and scutellum coriaceous, notauli weakly scrobiculate, meeting before scutellum in wide rugose area; mesopleuron weakly rugulose, nearly smooth above episternal scrobe, subalar sulcus strongly rugose, sternaulus slightly impressed and strongly rugose; propodeum nearly horizontal, strongly rugose, apical corners protruding, median carina very strong and complete, almost like a lamellate ridge. Legs : tarsal claws long and slender, not pectinate but with long thin spines on basal 1 / 2; hind coxa coriaceous dorsally. Wings : slightly dusky; fore wing with vein r nearly 2 / 3 length of 3 RSa and nearly 3 / 4 length of mcu, second submarginal cell nearly square, vein 1 cu­a beyond 1 M by distance less than length of 1 cu­a (Fig. 18); vein 1 CUa 1.4 length of 1 CUb; hind wing with vein RS arcuate, marginal cell narrowest in middle, vein 1 r­m shorter than 1 M, vein M+CU longer than 1 M, vein m­cu indicated by short infuscated line. Metasoma : first tergum short and broad, distinctly shorter than apical width, rugose striate, median carina complete; second tergum rugose striate, median carina complete; third tergum rugose striate, median carina on basal 4 / 5; fourth tergum rugose striate on basal 1 / 2, coriaceous on apical 1 / 2; rest of terga coriaceous; ovipositor about 1 / 2 length of hind basitarsus. Male . Essentially as in female; body usually entirely black, mesonotum often orange, coxae black. Holotype . Female: NORTHWEST TERRITORIES, Hazen Camp, 81 ° 49 ’N, 71 ° 18 ’W, July 3, 1964, R. E. Leech. Deposited in CNC. Paratypes . NORTHWEST TERRITORIES: 7 females, 7 males, same data as holotype with dates ranging from July 11, 1961 to July 2, 1964, collectors D. R. Olive, R. B. Madge and J. F. McAlpine; 1 female, 1, male, Eureka, Ellesmere Island, July 8–29, 1953, P. F. Bruggemann. YUKON TERRITORY: Tombstone C. G., July 10, 1977, Wharton coll. Deposited in CNC, USNM, RMSEL, TAMU. Distribution . Known only from the northern Canada. Biology . Pinned with the type series are caterpillar mummies (Fig. 2) that have subsequently been identified as the lymantriid Gynaephora rossii Curtis. Comments . This species is similar in coloration to dichromatus but differs in the longer antennae, shorter first metasomal tergum and the position of vein 1 cu­a in the fore wing which is close to vein 1 M. Etymology . The specific name is from the Latin aquilonius meaning northern or northerly in reference to the extreme northern locality of this species. : Published as part of Shaw, Scott R., Marsh, Paul M. & Fortier, Joseph C., 2006, Revision of Nearctic Aleiodes Wesmael (Part 8): the coxalis (Spinola) Species­Group (Hymenoptera: Braconidae, Rogadinae), pp. 1-30 in Zootaxa 1314 on pages 6-8, DOI: 10.5281/zenodo.173917
