Material: HOLOTYPE male THAILAND, Kanchanaburi Province, Sai Yok district, 14° 6ˏ 56˝ N, 99° 8ˏ40˝ E. 16 June 1986. L. Deharveng leg., ( MNHN).

Diagnosis: A species of the opinatus subgroup. Spatulate lobe ( sl) at the apical part of telopodite expanded, smooth and without a spine. Similar in this respect to T. bearti , T. chelatus , T. cristagalli , T. brachyacanthus , T. loxia and T. bispinus . Differs from the first five of these species by the mesal process of the anterior coxal fold ( amp) being longer than the lateral process of anterior coxal fold ( alp). Particularly similar to T. bispinus , differing from it by alp apically with a crest extending caudad and ending in a small spine ( Fig. 9 View FIGURE 9 C, arrow), amp apically irregularly tuberculate, the absence of telopodite lobe ( lo), and having a small spine ( ss) at base of apical part, opposite the origin of tibial spine.

Description: Adult male with 69 podous rings, no apodous rings. Length ca. 13 cm (broken), width ca. 7.0 mm. Color in life unknown; preserved specimen with prozona, epiproct, and paraprocts whitish-brown, Head, antennae, legs, metazona, tip of epiproct, margins of paraprocts, and hypoproct brown.

Gonopods ( Figs. 9 View FIGURE 9 A–E): Anterior coxal fold ( ac) ( Fig. 9 View FIGURE 9 A): lateral process ( alp) long, slender, regularly curved, in anterior view sickle-shaped, apically with a crest extending caudad and ending in a small spine ( Fig. 9 View FIGURE 9 C, arrow); mesal process ( amp) slightly longer than lateral process ( alp), protruding from middle of mesal margin of ac, apically irregularly tuberculate. Posterior coxal fold ( pc) ( Fig. 9 View FIGURE 9 B) basally with moderately high lateral paracoxites ( px); mesal process ( pmp) slender, directed distolaterad; lateral process ( plp) damaged on both sides of unique specimen. Telopodite ( Figs. 9 View FIGURE 9 D–E): Femoral spine ( fe) flattened, short, lying close to top of telopodite; tibial spine ( ti) very long, curving in horizontal plane; spatulate lobe ( sl) basally slender, distally broadly expanded, with inner lateral margin arched; a small accessory lobe ( al) at base of sl; and a small slender spine ( ss) at base of apical part, opposite the origin of the tibial spine; palette ( pa) simple, gutter-like, distally with about seven brownish blepharochaetae ( bp).

Distribution ( Fig. 20): Described from THAILAND, Kanchanaburi [Kanchanabrui], without an exact locality ( Demange, 1989). The more precise locality of the holotype, which is the only known specimen, is Kanchanaburi Province, Sai Yok district (L. Deharveng, personal communication).
