Diagnosis Using the latest key to Tylopus species (Likhitrakarn et al. 2016), as well as the information concerning all 12 congeners described since (Golovatch et al. 2016; Golovatch 2018, 2019, 2020; Golovatch and Semenyuk 2018), T. monticola sp. nov. keys out to T. rugosus Golovatch & Enghoff, 1993 on account of the particularly strong similarities in the gonopodal structure. Thus, even though they both share most of the somatic and gonopodal features, the new species differs in the large and long process z with a serrate edge along the dorsal margin, which protrudes be- yond the apicolateral lobe (l) (vs. smaller and not protruding be- yond l), all ♂ legs with the prefemora swollen laterally except for leg 1 (vs. except for legs 1 and 2), coupled with the pleurosternal carinae complete crests with an evident, sharp, caudal denticle produced past the rear tergal margin on segments 4–7, gradually decreasing in size until segments 15(16) (♂) or 13(12) (♀) (vs. same, but gradually decreasing in size until segment 18).
