Genus Trichopolydesmus Verhoeff, 1898

Type species.

Trichopolydesmus eremitis Verhoeff, 1898, by monotypy.

Diagnosis.

Differs from other European Trichopolydesmidae by the gonopod acropodite divided into three branches, where solenomere is thin, long and acuminate, and devoid of additional process.

In addition, the diagnosis can be amended with the following combination of characters: medium-sized species (8.5 mm), 20 body rings (including telson), sensilla basiconica on antennomere 6 partially exposed outside the pit, paraprocts and hypoproct densely setose (Fig. 5F, G ), metaterga with 4-6 irregular rows of long trichoid setae, podomeres of anterior legs in males with denticles on their ventral side, tarsi with rare sphaerotrichomes (Fig. 5H, I ).
