Diagnosis.

A genus of Orthomorphini with 20 segments. Body small-sized, adults ca 18-20 mm long, ca 2.2-2.8 mm wide on midbody metazona. Paraterga moderately well developed, metazonite to prozonite width ratio being ca 1.3. Adenostyles missing. Sternal lobe or cone(s) between ♂ coxae 4 present or absent.

Gonopod with a long subcylindrical coxite and a usual, cylindrical cannula. Telopodite long and slender, modestly curved. Prefemoral part densely setose, more than 2 times shorter than femorite. The latter without evidence of torsion, slightly enlarged distally, without sulcus demarcating a “postfemoral” part. Solenophore consisting of subequally modestly developed laminae lateralis, and medialis, both sheathing a similarly long, simple, flagelliform solenomere with a barely exposed tip; tip of solenophore never deeply split, poorly bi- or trifid, at least some of its apical prongs being short spines.
