Atractides abditus Bader 1955

Species dubia

Type series: Missing. Locus typicus: Höhlen von S. Canziano (Rinaldini- Dom); following Stammer (1932): collecting site R3, 1928/1929

Discussion: ‘ Atractides abditus (Walter) ’ was first published as a nomen nudum in a faunistic survey of the Timavo catchment in eastern Italy / Slovenia (Stammer, 1932). Bader found the female on which this species should be based and gave a ‘posthumous’ description. Since then, it has not been discussed and the type specimen is now lost. Characters of eventual taxonomic importance provided in that description are: integument striated, idiosoma L/W 800/585, glandularia diameter max. 30 Mm; caudal apodemes Cx-2 slightly protruding, suture Cx-3/4 strongly curved and in its medial part directed caudally; I-L-5/6 L 205/166 (ratio 1.23) median setal interspace, S-2 larger than S-1, I-L-6 curved, only slightly thinning in the centre; gonopore L 150, genital plates L 100 Mm, L Ac-1> Ac- 2/3, excretory pore smooth (?) position of Vgl-1 unclear; palp L 360 Mm, ventral margins of P-2 not strongly convex, of P-3 slightly concave, of P-4 straight; P-4 ventral sectors 1: 1: 1, sword seta between ventral hair insertions.

In view of the Ac arranged in a weakly curved line, Bader regarded it as related to the little known A. arcuatus and restricted the discussion to some measurement differences between these two taxa. Due to the scanty information, and in view of the absence of type material, no interpretation of A. abditus is possible and it remains a species dubia.

palp: weak sexual dimorphism, ventral margins P-2/3 straight, without extensions, sword seta P-4 strong, between ventral hair insertions, but approached to distoventral hair
