Diagnosis.

A genus of Opisotretidae with 19 (♂) or 20 (♀) body segments. ♂ head often, but not always, with modifications on vertex, collum rarely enlarged. Most of metaterga with 2 (more rarely) or 3 (more usually) regular, transverse rows of bacilliform setae. Frontolateral margin of midbody paraterga usually without evident shoulders, in any event not so strongly developed as to cause a caudad shift of the rows of tergal setae. Ozopore lying from close to, to rather far in front of caudal margin of paratergite’s caudolateral corner.

Gonopod telopodite rather stout, at least basal half so, unipartite, usually only faintly curved, slightly, more usually clearly, hollow/excavate/flattened on caudal face all along; parabasal and/or distal parts with lobes or processes, sometimes including p; both accessory seminal chamber and hairy pulvillus wanting, but a very short, dentiform solenomere usually ornamented with a few bacilli- or setiform structures nearby often present (Figs 9, 10C, D, 28 E–I, 29, 31 E–H, 32, 35).

Type species.

Martensodesmus himalayensis Golovatch, 1987, by original designation.

Remarks. In addition to the type species, the genus currently contains further four Himalayan congeners: Martensodesmus bicuspidatus Golovatch, 1988, Martensodesmus excornis Golovatch, 1988, Martensodesmus nagarjungicus Golovatch, 1987 and Martensodesmus sherpa Golovatch, 1987, as well as one new species in Vietnam and two more in southern China. A key to Martensodesmus species is given below.
