Genus Attemsostreptus Verhoeff, 1941

Diagnosis

Readily distinguishable from other genera of Spirostreptidae by the extremely long, slender lateral metaplical processes, in combination with the ‘trachystreptinine’ habitus, i.e., with marked longitudinal striae/keels over the entire body ring circumference. Krabbe (1982) presented a more detailed diagnosis, based mainly on male secondary sexual characters, as follows (translated from German and slightly modified): collum without longitudinal keels. First pair of legs with strong ‘shoulders’; the outer margin of the coxosternum smooth with 4 lateral small setae; prefemoral processes divergent, short, triangular with gently rounded margins, prefemora and prefemoral processes with pores. Gonopod sternum low and small; coxae slender, proplica (pp) simple, straight, bearing a few setae distally; metaplicae (mp) apically round to angular with extremely elongated lateral processes (lap) tapering into a claw-like apex, distally round to subrectangular; telopodite slender with a long, thin antetorsal process (atp), distal to (atp) becoming even slenderer, apex bifurcate with a thin serrated lamella and an acuminate apical process.
