Material examined. HOLOTYPE male THAILAND, Rayong Province, Muang district, Koh Samet, 12° 33ˏ 27˝ N, 101° 27ˏ 13˝ E. 12 August 2010. P. Pimvichai, P. Prasankok and U. Bantaowong leg., ( CUMZ).– Paratypes: 10 males and 10 females, same data as holotype ( CUMZ), 3 males, 3 females, same data as holotype ( ZMUC). 3 males and 2 females, same locality, 18 September 2008. P. Decker leg. ( ZMUC).

Etymology. The species epithet is a Latin adjective and refers to the laterad orientation of the lobe distal to the gonopodal femoral process.

Diagnosis. A species of the induratus subgroup. Telopodite with a round lobe (lo) projecting distolaterad distally to fe. Similar in this respect to T. dormiens . Differs from all other species of the T. induratus subgroup by having anterior coxal fold (ac) distolaterally rounded, distomesally produced in distad rounded lobe and by having the extremely high mesal process of posterior coxal fold (pmp), rounded, distally directed anteriad (slightly laterad).

Description. Adult males with 55–58 podous rings, no apodous rings. Length ca. 9–10 cm, width ca. 6.1–7.1 mm. Adult females with 56–58 podous rings, no apodous rings. Length ca. 11–12 cm, width ca. 7.3–8.3 mm. Overall color of living animal ( Fig. 9 View FIGURE 9. A D) dark brown.

Gonopods ( Figs. 7 View FIGURE 7 A–D): Anterior coxal fold (ac) ( Fig. 7 View FIGURE 7 A) basally narrow, gradually widening towards tip, distolaterally rounded, distomesally produced in distad rounded lobe. Posterior coxal fold (pc) ( Fig. 7 View FIGURE 7 B) basally with moderately high lateral paracoxites (px); mesal process (pmp) extremely high, rounded, distally directed anteriad (slightly laterad). Telopodite ( Figs. 7 View FIGURE 7 C–D) leaving coxite over shelf (sh) of posterior coxal fold; femoral spine (fe) long, slender, ending in sharp point, in situ curving above apical part of ac, telopodite distally to fe with a round lobe (lo) projecting distolaterad; tibial spine (ti) very long, slender, curving in an oblique-sagittal plane, in situ resting between the two ac; apical part: lamellar lobe (ll) flattened, broadly expanded, rounded, transparent; palette (pa) simple, basally with an uncate subterminal lobe (ucl) ventrally; distally with about five brownish blepharochaetae (bp).

Distribution ( Fig. 11 View FIGURE 11 ). Known only from the type locality.
