Profemora rather slender, 3.16 × as long as broad, and slightly broader than protibiae ( Fig. 13A ). 2. Vertex elongate, 2.10 × as long as broad ( Fig. 13F ). 3. Vertex and anterior portion of pronotum medium brown ( Figs 13F ). Differential diagnosis This species differs from C. ( Cleotyche ) francescoi sp. nov. and C. ( Cleotyche ) mariae Emeljanov, 1997 by its relatively more slender profemora (profemora 3.16 × as long as broad vs max. 2.91 × in the two other species). The most similar species is C. ( Cleotyche ) christinae sp. nov. which differs by its narrower profemora (3.78 × as long as broad vs 3.16 × in C. ( Cleotyche ) montana sp. nov. ), and the proportions of the vertex (vertex 2.10 × as long as broad vs 1.56 × in C. ( Cleotyche ) christinae sp. nov. ). Etymology The species epithet is a Latin adjective meaning ‘associated with mountain’ and refers to the mountainous habitat on top of Blackdown Tableland where the species was discovered.

Rufous-brown with clypeus black; labium brown with terminal segment black. Vertex elongate, 2.10 × as long as broad, projected anteriorly, rounded to a blunt point apically, with median carina not reaching anterior margin and with lateral margins carinate, subparallel along eye and incurved anteriorly; posterior margin roundly incurved. Frons elongate, very weakly concave in lateral view, with sides subparallel, weakly narrowing along eyes, 3.29 × as long as broad, anteriorly pointly rounded in perpendicular view, with three complete carinae, one median and one along each lateral margin, all extending to apex of clypeus; two weak, short carinae between median and sublateral carinae extending from dorsal margin along 1 /5 of the way along the frons. Clypeus elongate and narrow, triangular. Eyes rather large, moderately protruding laterally. Antennae with scape short and cylindrical; pedicel short, inflated, barrel-shaped and with large sensory plates on ventral portion. Ocelli absent. Labium elongate and narrow, reaching posterior trochanters and with apical segment elongate, about half as long as penultimate one. THORAX ( Fig. 13E–H ). Pronotum rufous-brown with posterior half whitish, paranotal lobes slightly darker towards posterior and ventral margins; mesonotum dark brown, darker than anterior portion of pronotum, with apex of scutellum slightly paler; thoracic sternites dark brown. Pronotum smooth with anterior margin strongly bisinuate, roundly projecting anteriorly behind vertex and roundly emarginate behind eyes, and posterior margin weakly incurved; median longitudinal carina and two lateral carinae on disc merging anteriorly along anterior margin; lateral carina behind eye; paranotal lobe angularly rounded posteroventrally. Mesonotum very short, about ⅔ as long as pronotum, smooth with three hardly visible obsolete carinae prolongating pronotal ones. Tegulae absent. Fig. 15.

Rufous-brown as mesonotum with rather broad white band along posterior margin, covering slightly less than 1 /5 of tegmina length; slightly elongate in dorsal view, 1.32 × as long as broad, slightly broadening from base to apex, broadly truncate apically, slightly rounded along lateral apical margin, convex, smooth; no trace of venation. LEGS ( Fig. 13A–D, I ). Brown with profemora along lateral margins, protibiae and metafemora dark brown; pro- and mesocoxae and trochanters black-brown; apical pale yellowish interrupted ring on pro- and mesofemora; protibiae with basal pale yellow marking dorsally and ventrally; protarsi white; base of metatibiae darker; metatibiae turning yellowish from base to apex; metatarsomeres brown with first one whitish on basal ⅔. Profemora and protibiae moderately foliaceous, rather slender, 3.16 and 3.52 × as long as broad, respectively; protibiae 0.92 × as broad as profemora; profemora with anterior margin weakly curved and posterior margin broadly rounded, with about 15 small teeth, teeth progressively smaller towards base of femur; protibiae with margins broadly rounded, external margin rather straight along median ⅔, and roundly truncate apically; median and posterior legs elongate and slender; metatibiae broadening towards apex, with one ventrolateral spine at distal 3 /5 and 6 apical spines; first and second metatarsomeres with strong spine at each side and apical row of 12 platellae ventrally. Metatibiotarsal formula: (2) 6 (2-4)/2/2. ABDOMEN ( Fig. 13A–D ). Black with median yellowish marking on last segment in male (female unknown); small yellowish marking on anal tube at base of anal column. Abdomen dorsoventrally flattened and smooth. MALE TERMINALIA ( Fig. 14 ).
