Female diagnosis Body color: head, including antennae, mesosoma and metasoma black, head often with yellow marking on face and vertex, pronotum often entirely or partly yellow, mesonotum sometimes with yellow spots at anterior lateral corners, second metasomal terga often yellow; legs yellow, fore and middle tarsus light brown, hind femur at apex, hind tibia and tarsus brown; wings hyaline, veins brown, tegula yellow. Body length, 3.5–4.5 mm; fore wing length, 3.0–3.5 mm. Head: eyes and ocelli small; 42–43 antennomeres, all flagellomeres slightly longer than wide; malar space moderate, equal in length to basal wisth of mandible and 1/3 eye height; temple narrow, about 1/2 eye width; occipital carina complete, reaching hypostomal carina; oral space small and circular, diameter equal to basal width of mandible and 1/2 face height; clypeus weakly swollen; ocelli small, ocellocular distance slightly greater than diameter of lateral ocellus; head coriaceous, face and vertex sometimes weakly rugulose; maxillary palpus not swollen; mandible small, tips not crossing when closed. Mesosoma: pronotum procate laterally along median line, remainder weakly coriaceous; mesonotum and scutellum strongly coriaceous and dull, notauli weakly scrobiculate, meeting in weakly rugose area before scutellum; mesopleuron coriaceous, subalar sulcus weakly rugulose, sternaulus absent, area above episternal scrobe often smooth; propodeum strongly areolate dorsally, coriaceous laterally, median carina strong and complete, forked at extreme apex. Legs: tarsal claws not pectinate; hind coxa weakly coriaceous dorsally. Wings: fore wing with vein r 2/3 length of 3RSa and m­cu, vein 1cu­a beyond 1M by distance equal to length of 1cu­a, vein 1CUa about 1/4 length of 1CUb; hind wing with vein RS weakly sinuate, marginal cell narrowest in middle, vein 1r­m 2/3 length of 1M, vein 1M about 2/3 length of M+CU, vein m­cu represented by weak fuscous line. Metasoma: first tergum costaterugose, longer than apical width, median carina complete; second tergum costate­rugose, median carina complete; third tergum rugose, median carina complete; fourth tergum rugose; remainder of terga weakly coriaceous; ovipositor about 1/2 length of hind basitarsus.

Distribution. The majority of specimens in the type series are from the maritime provinces of Newfoundland, New Brunswick and Nova Scotia. However, a few specimens from central and eastern Canada and Alaska are also included, indicating this species is widespread in northern North America.

Biology. Specimens have been reared from the following geometrids: Semiothisa granitata Gn. , S. sexmaculata Cam. , and S. dispuncta .

Comments. This species is similar to A. itamevorus but is distinguished by the weak vein m­cu in the hind wing and the costate­rugose metasomal terga. The specific name is from the Latin maritimus meaning “of the sea” in reference to the distribution of many specimens of the type series in the maritime provinces of Canada. However, there are scattered records from central Canada and Alaska.
