Body color : ( Fig. 5 ) head orange, vertex, ocellar triangle and mesopleuron sometimes marked with black, antenna black; mesonotum, pronotum and legs orange; mesopleuron black, sometimes marked with orange; propodeum usually black, sometimes orange laterally; metasoma usually black, sometimes orange escept for first tergum; wings slightly dusky, veins brown, stigma usually bicolored brown, yellow at base. Body length , 5–6 mm ; fore wing length, 4–5 mm . Head : eyes and ocelli normal size; 35 antennomeres, flagellomeres beyond second as wide as long, first flagellomere slightly longer than second; malar space long, about 2/3 eye height and 2 times basal width of mandible; temple broad, nearly equal to eye width; occipital carina complete, meeting hypostomal carina; oral space small, width less than malar space and face height; clypeus not swollen; ocelli small, ocellocular distance 2 times diameter of lateral ocellus; face, frons and vertex rugose, temple coriaceous; maxillary palpus not swollen; mandible small, tips not crossing when closed. Mesosoma : pronotum rugose, coriaceous basally; mesonotum and scutellum coriaceous; notauli scrobiculate, meeting posteriorly in wide rugose area; mesopleuron, including subalar sulcus and sternaulus, rugose, smooth and shining above episternal scrobe; propodeum rugose, median carina weak but complete. Legs : tarsal claws not pectinate but with 4–5 thin spines on basal half; inner spur of hind tibia shorter than half length of basitarsus; hind coxa rugulose coriaceous dorsally. Wings : slightly infumated; fore wing with vein r 1/2 length of 3RSa and 2/3 length of m­cu, vein 1cu­a beyond 1M by distance very slightly greater than length of 1cu­a, vein 1CUa 1/3 length of 1CUb; hind wing with vein RS slightly arched in middle, marginal cell narrowest in middle, vein 1r­m slightly shorter than 1M, M+CU longer than 1M, vein m­cu indicated by short spectral ridge. Metasoma : terga 1–3 strongly rugose costate, median carina complete on terga 1–2 and at least on basal half of tergum 3; tergum 4 weakly rugose at extreme base, coriaceous apically; remainder of terga coriaceous; first tergum about as long as apical width; ovipositor exerted, about 2/3 length of hind basitarsus Male . Essentially as in female except body black, legs beyond coxa orange, stigma often entirely brown. Holotype Female: CALIFORNIA, Sagehen Crk. nr.

Head and mesosomal characters of the Aleiodes coxalis species­group. 11, A. aciculatus pronotum; 12, A. brevis pronotum; 13, A. aciculatus vertex; 14, A. wyomingensis vertex; 15, A sanctihyacinthi vertex (Arrow indicates yellow coloration around eye); 16, A. quadratus propodeum (Arrows indicate tubercles). Distribution . Known from northwestern North America including Alaska. Biology . Unknown. Comments . This species is similar to sanctihyacinthi but differs in its black abdomen and shorter antennae.
