ATRACTIDES ARCUATUS ( THOR, 1914) ( FIG. 25A,B View Figure 25 )
Syn. A. dubius ( Sokolow, 1940) : syn. nov.
Type series: Lost with the distruction of the Thor collection. Locus typicus: small mountain brook near Ordubat, at the Russian-Persian frontier, 10.6.1913 1 ♂, 17.6.1913 1 ♀ .
Material examined: A. dubius Sokolow, 1940 , Holotype; NHMB Megapus piersigi Walter ♂ coll. Piersig; Typus; P.S. = arcuatus ? pasted over with a label Megapus piersigi Walter = arcuatus .... Two slides: IX/01, 457, idiosoma; IX/02, 457a gnathosoma, both completely desiccated. Walter probably planned to describe this specimen from the Piersig collection under the name of A. piersigi , but convinced himself that it was identical to A. arcuatus before publishing the name. Both due to the lack of label indicating collecting site and poor state of conservation, it does not merit further attention.
Description:
General features dorsal integument: lineated?; muscle attachments: unsclerotized coxal field: sexual dimorphism?
I-L: I-L-5 S-1 and -2 interspaced, similar in shape and dimensions, I-L-6 not particularly long, curved genital field: Ac elliptical-roundish, in a weakly curved line, Ac-2 not shifted laterally excretory pore: unsclerotized?; Vgl-1: not fused to Vgl-2
palp: sexual dimorphism, P-4 sword seta near distoventral hair
Males
Translation of the original description, with additions deduced from Thor’s figures: coxal field: Cx-1 + 2 and Cx-3 + 4 fused to an unique coxal shield (?) genital field: anterior and posterior margins with very shallow indentations,
the caudal indentation filled with secondary sclerite, numerous hairs flanking the gonopore; genital setae: 60 palp: P-2 ventrally convexly swollen, with a nearly spherical aspect, P-3 ventral margin slightly concave; P-4 ventrally thickened with maximum H
