128 A. Fjellberg Fig. 2. A. sefitentrionalis. Dorsal chaetotaxy of Th. 11-111. with a distinct tooth at the middle of inner edge. Empodium sharply pointed, approximately l/4 of inner length of claw (Fig. 9). Macrochaeta of thorax and abdomen well differentiated, pointed. Some of the curved setae of Abd. V-VI (the segments are fused) distinctly serrated. Number of setae along dorsal median line of Th. 11 - Abd. 111 of adults (variation in parenthesis): 7 (6-9), 6 (4-7), 5 (3-6), 5 (4-6), 5 (6). Th. 11 with 1 + 1 setae along linea ventralis (abnormally one may be lost or doubled), Th. 111 with 3 - 5 setae at each side of linea ventralis (highly variable) (Fig. 3). Head with 4 -t 4 setae along linea ventralis. Ventral tube with 4 caudal and 3 + 3 lateral setae. Ant. IV with numerous curved sensorial hairs. Fig. 3. A. atlanticr~s n. sp. Ventral chaetotaxy of Th. 1 - Abd. 1. AFFINTTIES The new species is related to A. sefitentrionazis Palissa, 1966, but is immediately recognized by the 1 + 1 ventral setae of Th. 11, which are not present in A. septentrionalis. Also the PAO is slightly smaller and more roundish, the cuticula structure is finer, and the dorsal clothing of setae is richer (Figs. 1 and 2). A. septentrionalis has never more than 4 + 4 setae along dorsal median line of Abd. 1, whereas A. atlanticus usually has 5 + 5. The inner edge of claws is untoothed in A. septentrionalis. A. atlanticus is a smaller, more parallel species (Figs. 4 and 5). The specimens collected in May, which are reproductive adults, measure 0.7-1.0 mm. Equivalent specimens of A. sefitentrionalis measure 0.8-1.3 mm.
