Diagnosis

A species of the opinatus subgroup. Mesal margin of anterior coxal fold (alp) with fine serrations. Similar in this respect to T. opinatus . Differs from this species by having the lateral process (alp)

slender, regularly curved and by having the mesal process (amp) broadly expanded and forming a strong longitudinal crest (lc) in posterior view.

Etymology

The species is named after the Royal Thai Navy, in recognition of their kind assistance which enabled us to pursue the necessary fieldwork at the type locality, and also after Chulalongkorn University where pink is the symbolic colour of the university, indirectly referring to the pink legs of the species; the species name is treated as a noun in apposition.

Paratypes

THAILAND: 5 ³³, 1 ♀, same data as holotype ( CUMZ-D 00089); 2 ³³, same data as holotype ( ZMUC).

Description

Adult males with 58–62 podous rings, no apodous rings. Length 11–12 cm, width 6.2–7.2 mm. Adult female with 60 podous rings, no apodous rings. Length 14 cm, width 8.0 mm. Overall colour of living animal ( Fig. 11A View Fig ) dark brown, shiny. Legs and antennae pink; preserved specimen with head, antennae, prozona, legs, epiproct, paraprocts and hypoproct brown; metazona dark brown.

GONOPODS ( Fig. 6 View Fig A–D). Anterior coxal fold (ac; Fig. 6A View Fig ): lateral process (alp) slender, regularly curved, mesal margin with fine serrations; mesal process (amp) almost as long as alp, broadly expanded, apically sharp, straight distad, in posterior view mesal margin of amp forming strong longitudinal crest (lc). Posterior coxal fold (pc; Fig. 6B View Fig ) basally with moderately high lateral paracoxites (px), distally with two processes: mesal process (pmp) shorter than plp, curving behind plp; lateral process (plp) flattened, directed distad. Telopodite ( Fig. 6 View Fig C–D) leaving coxite between pmp and plp; femoral spine (fe) very long, curving almost exclusively in horizontal plane; tibial spine (ti) very long, curving in horizontal plane close to basal part of fe; spatulate lobe (sl) terminating in sharp spine; palette (pa) simple, gutterlike, distally with about twelve brownish blepharochaetae (bp), laterally with few sharp spines.
