Summary: | 1. Psammostiba comparabilis (Mäklin in Mannerheim, 1853), comb. nov. (Figs. 64, 66, 6877) Homalota comparabilis Mäklin in Mannerheim, 1853: 181. Atheta ( Metaxya ) comparabilis : Fenyes, 1920: 199 (as valid species). Atheta ( Metaxya ) comparabilis : Bernhauer & Scheerpeltz, 1926: 613 (as valid species). Atheta ( Brundinia ) comparabilis : Moore & Legner, 1975: 357 (as valid species). Philhygra comparabilis : Seevers, 1978: 266 (as valid species). Adota comparabilis : Lohse & Smetana, 1985: 294 (as valid species). Type material. Lectotype of Homalota comparabilis (designated by Lohse and Smetana (1985)), UNITED STATES: Alaska: Kodiak (MZHF). Additional material . UNITED STATES: Alaska: Kenai Peninsula Co.: 15 specimens, Homer, S shore of Homer spit, 59º36.33'N 151º25.71'W, sandy seashore, in seaweed (V.I.Gusarov), 22.vii.1998 (AMNH, SPSU); California: Mendocino Co.: 2, Needle Rock, on beach (D.Giuliani), 6.x.1974 (UCR); CANADA: British Columbia: 2, 4, Queen Charlotte Islands, Graham Island, Toe Hill, "ex on rocks in intertidal" (J.S.Ashe), 14.vii.1988 (KSEM);, Victoria (CASC). Diagnosis . Psammostiba comparabilis can be distinguished from P. kenaii by larger body, larger aedeagus with wider apex (Figs. 7374; 8283) and larger spermatheca (Figs. 77; 87). Psammostiba comparabilis can be distinguished from the Palaearctic species of Psammostiba by the fine crenulation of the posterior margin of male tergum 8 (Fig. 69), and by the distinct shape of aedeagus (Figs. 68, 7376) and spermatheca (Fig. 77). Description . Length 4.0 4.6 mm. Body black with brown legs and light brown tarsi. Head surface matte, with strong and dense isodiametric microsculpture, with fine punctation, distance between punctures equals their diameter; in both sexes with weak medial impression. Temple length to eye length ratio 0.91.1. Antennal article 3 is 1.2 times as long as article 2, articles 410 elongate (ratios 1.5 (45), 1.4 (6), 1.3 (7) and 1.1 (8 10)), article 11 shorter than articles 9 and 10 combined (Fig. 54). ... |
