S Campbell River (J.M. & B.A.Campbell), 22.vii. 1975 (CNCI);,, Massett (BMNH). Diagnosis . Adota maritima is very similar to Ad. gnypetoides , but differs in having larger body size, longer antennal segments (Figs. 18; 17), wider apex of median lobe (Figs. 2324; 3536), posterior margin of male tergum 8 emarginate medially (Fig. 19) and larger spermatheca (Figs. 2930; 4041). Adota maritima differs from Ad. colpophila by having matte body, posterior margin of male tergum 8 with four blunt projections (Fig. 19), median lobe with blunt apex (Figs. 23 24; 4647) and the distinct shape of spermatheca (Figs. 2930). Description . Length 2.53.2 mm. Body black with dark brown legs and light brown tarsi. Head surface matte, with strong and dense isodiametric microsculpture, with fine punctation, distance between punctures equals 12 times their diameter. Frons with sparser punctation, in both sexes with longitudinal impression. Temple length to eye length ratio 1.0 1.2. Antennal article 2 is 1.1 times as long as article 3, articles 45 slightly elongate (length to width ratio 1.21.3), articles 67 as long as wide, articles 810 slightly transverse (length to width ratio 0.8) (Fig. 18). Pronotum subquadrate or slightly transverse, 1.1 times as wide as head, width 0.47 0.61 mm, length 0.410.51 mm, width to length ratio 1.2; matte, with strong and dense isodiametric microsculpture; punctation finer than on head, poorly visible on matte background. Elytra much wider (0.630.89 mm) and longer (0.570.79 mm; measured from humeral angle) than pronotum (elytral length to pronotal length ratio 1.5), 1.1 times wider than long, surface matte, with strong and dense isodiametric microsculpture; punctation poorly visible. Abdominal terga matte, with strong and dense isodiametric microsculpture; with fine punctation, distance between punctures equals 23 times their diameter on terga 35 and 3 5 times on terga 67. Apical margin of tergum 7 with white palisade fringe. Posterior margin of male tergum 8 with four blunt projections, emarginate medially (Fig. 19). Aedeagus as in Figs. 2328, median lobe with wide apex (Figs. 2324). Spermatheca as in Figs. 2930. Discussion. The types of Homalota maritima , Atheta massettensis , At. subintima , At. setositarsis , At. scortea , At. scolopacina and At. insons fall within the range of variability of Adota maritima and have similar shape of genitalia and male abdominal tergum 8. The holotype of Atheta insons is smaller (pronotal width 0.47 mm) than most specimens of Adota maritima . However, it differs from Adota gnypetoides by the wide apex of median lobe and the shape of posterior margin of the male tergum 8, and I interpret it as a small specimen of Ad. maritima . Examined specimens of Ad. maritima from southern California are smaller than the specimens from British Columbia and Alaska and approach in size examined specimens of Ad. gnypetoides . Additional collecting is needed to study the variability of Ad. maritima . Distribution. Known from the Pacific coast of North America, from Alaska to California (Fig. 52). Natural History. Adota maritima is a littoral species, common in decomposing seaweed on a beach. : Published as part of Gusarov, Vladimir I., 2003, A revision of Nearctic species of the genera Adota Casey, 1910 and Psammostiba Yosii & Sawada, 1976 (Coleoptera: Staphylinidae: Aleocharinae), pp. 1-35 in Zootaxa 185 on pages 9-14, DOI: 10.5281/zenodo.156388 : {"references": ["Mannerheim, C.

Adota maritima is very similar to Ad. gnypetoides , but differs in having larger body size, longer antennal segments (Figs. 18; 17), wider apex of median lobe (Figs. 2324; 3536), posterior margin of male tergum 8 emarginate medially (Fig. 19) and larger spermatheca (Figs. 2930; 4041). Adota maritima differs from Ad. colpophila by having matte body, posterior margin of male tergum 8 with four blunt projections (Fig. 19), median lobe with blunt apex (Figs. 23 24; 4647) and the distinct shape of spermatheca (Figs. 2930). Description . Length 2.53.2 mm. Body black with dark brown legs and light brown tarsi. Head surface matte, with strong and dense isodiametric microsculpture, with fine punctation, distance between punctures equals 12 times their diameter. Frons with sparser punctation, in both sexes with longitudinal impression. Temple length to eye length ratio 1.0 1.2. Antennal article 2 is 1.1 times as long as article 3, articles 45 slightly elongate (length to width ratio 1.21.3), articles 67 as long as wide, articles 810 slightly transverse (length to width ratio 0.8) (Fig. 18). Pronotum subquadrate or slightly transverse, 1.1 times as wide as head, width 0.47 0.61 mm, length 0.410.51 mm, width to length ratio 1.2; matte, with strong and dense isodiametric microsculpture; punctation finer than on head, poorly visible on matte background. Elytra much wider (0.630.89 mm) and longer (0.570.79 mm; measured from humeral angle) than pronotum (elytral length to pronotal length ratio 1.5), 1.1 times wider than long, surface matte, with strong and dense isodiametric microsculpture; punctation poorly visible. Abdominal terga matte, with strong and dense isodiametric microsculpture; with fine punctation, distance between punctures equals 23 times their diameter on terga 35 and 3 5 times on terga 67. Apical margin of tergum 7 with white palisade fringe. Posterior margin of male tergum 8 with four blunt projections, emarginate medially (Fig. 19). Aedeagus as in Figs. 2328, median lobe with wide apex (Figs. 2324). Spermatheca as in Figs. 2930. Discussion. The types of Homalota maritima , Atheta massettensis , At. subintima , At. setositarsis , At. scortea , At. scolopacina and At. insons fall within the range of variability of Adota maritima and have similar shape of genitalia and male abdominal tergum 8. The holotype of Atheta insons is smaller (pronotal width 0.47 mm) than most specimens of Adota maritima . However, it differs from Adota gnypetoides by the wide apex of median lobe and the shape of posterior margin of the male tergum 8, and I interpret it as a small specimen of Ad. maritima . Examined specimens of Ad. maritima from southern California are smaller than the specimens from British Columbia and Alaska and approach in size examined specimens of Ad. gnypetoides . Additional collecting is needed to study the variability of Ad. maritima . Distribution. Known from the Pacific coast of North America, from Alaska to California (Fig. 52). Natural History. Adota maritima is a littoral species, common in decomposing seaweed on a beach. : Published as part of Gusarov, Vladimir I., 2003, A revision of Nearctic species of the genera Adota Casey, 1910 and Psammostiba Yosii & Sawada, 1976 (Coleoptera: Staphylinidae: Aleocharinae), pp. 1-35 in Zootaxa 185 on pages 9-14, DOI: 10.5281/zenodo.156388 : {"references": ["Mannerheim, C.
