Archispirostreptus microgigas sp. nov.

Figs 1, 2, 4

Diagnosis. Differs from all other species of Archispirostreptus by having a completely smooth antetorsal process and by having fewer body rings. Differs from all congeners except A. gigas (Peters, 1855) and A. divergens Krabbe & Enghoff, 1978, by having a rounded lobe on the gonopod telopodite, distal to the antetorsal process.

Etymology. From Greek mikró (small) and gigas (giant), i.e. a small giant, referring to the relatively small size, especially the low number of body rings. Noun in apposition.
