Syntype

♂ of Anoplodesmus mutilatus (NHMW-4245), locality unknown; a slide with mounted gonopod.

Gonopod (Fig. 14) rather simple. Coxa long and slender, with several setae distodorsally. Prefemur densely setose, nearly 1/3 as long as femorite + “postfemoral” part. Femorite stout, slightly curved, slightly enlarged distad, showing a mesal groove, “postfemoral” part demarcated by an oblique lateral sulcus; lobe l simple; process h long, rather simple, slightly curved, tip small and bifid; process z high, slightly curved, tip acute; solenophore long and slender, typically coiled, tip microdenticulate.

Remark.

This species was described both from Luang Prabang, Xieng Kuang, Laos and Pic de Langbiang (Mount Langbian), Lamdong Province, Vietnam ( Attems 1953). Golovatch (1984) redescribed and illustrated only a gonopod, but the locality remained unclear. As all our attempts at locating a torso of Tylopus sigma in the collection of the Naturhistorisches Museum Wien, Austria had failed, we could only revise the very same right gonopod mounted on a slide. Fortunately, the gonopod is easily distinguished from congeners.
