Description
Summary:Scaptognathus hallezi Trouessart, 1894 Diagnosis. Glp-1 same level as Ds-1. Ds-2 on AD. PE with 1 dorsal seta. GA bipartite in female and male. Female with 3 or 4 Pgs and 4 Sgs. Male with 30–40 Pgs and 6 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 2-(1,2)- (1,2)-(1,2) setae; Tf I–IV with (4,5)-4-2-2 setae, 2-0-0-0 Bp setae; Gn I–IV with (2,4)-(3,5)-3-3 setae, 2-1-0-0 Bp setae; Tb I–IV with (7,9)-6-(6,7)-(5,7) setae, 6-3-4-4 Bp setae; Ta I–IV with 3-3-3-3 dorsal setae, 1-1-0-0 Bp setae. Lc I with accessory process. Idiosoma length 223–260 in female, 223–241 in male. Idiosoma width 126 (idiosoma length 231) in female, 145–148 (idiosoma length 237–240) in male. Gnathosoma length 148–167 (idiosoma length 223–260) in female, 148–155 (idiosoma length 223–241) in male. Ratio of gnathosoma to idiosoma 0.66–0.71 in female, 0.62–0.69 in male. Ratio of P-2 to P-1 3.17. Remarks. This species is similar to S. sabularius and S. tereninus in having Ds-2 on AD. However, S. hallezi differs from the latter two species in the shape of GA in female. Bartsch (1986) suggested that S. neretinus Morselli & Mari, 1981 would be synonymous with S. hallezi . Female and male are known. Habitat. Littoral–Sublittoral zones: Medium to coarse sandy sediment, algae, and bryozoans at intertidal zone to 58 m depth. Distribution. North Atlantic Ocean: Roscoff, Granville [France]. Mediterranean: Île If, Île Ratonneau, Île Riou, Île Jarre, Plateau des Chevres, Envau, Port-Pin [France]. Lido Frascone (Puglia), Lido dell’Ancora [Italy]. Kaþ, Hamitbey Plajý (Antalya) [Turkey]. Indian Ocean: Waltair [India]. References.
