Fig. 5 A–E
Diagnosis
A species of the opinatus subgroup. Lateral process of anterior coxal fold (alp) slender, curving mesad; mesal process of anterior coxal fold (amp) as long as alp, slender, straight, directed distad. Similar in these respects to T. demangei. Differs from this species by having mesal margin of amp forming a strong longitudinal crest (lc) in posterior view, by having only one femoral spine (fe) and by having the spatulate lobe (sl) broad and rounded.
Etymology
The name is a Latin adjective, referring to the longitudinal crest on the mesal process of the anterior coxal fold.
Material examined
Holotype THAILAND: ♂, Songkhla Province, Rattaphum District, Srikasorn, 7°00'18" N, 100°08'24" E, 12 Jan. 2009, leg. P. Pimvichai, C. Sutcharit and members of the Animal Systematics Research Unit (CUMZ-D00094).
Paratype THAILAND: ♂, same data as holotype (CUMZ-D00077).
Description
Adult males with 61–66 podous rings, no apodous rings. Length 16–17 cm, width 9.2–9.5 mm. Colour in life unknown; preserved specimens with head, antennae, prozona and legs brown; metazona, epiproct, paraprocts and hypoproct reddish brown.
GONOPODS (Fig. 5 A–E). Anterior coxal fold (ac; Fig. 5A): lateral process (alp) slender, curving mesad, with lateral serrate crest near tip (Fig. 5C, arrow); mesal process (amp) as long as alp, slender, straight, directed distad, tip sharp, pointed, in posterior view mesal margin of amp forming strong longitudinal crest (lc). Posterior coxal fold (pc; Fig. 5B) basally with moderately high lateral paracoxites (px), distally with two processes: mesal process (pmp) slender, directed anteriad; lateral process (plp) short, erect, digitiform; forming shelf for accommodation of telopodite. Telopodite (Fig. 5 D–E) leaving coxite between pmp and plp; femoral spine (fe) long, curved downward, with expanded lamella at base; tibial spine (ti) very long, curving in horizontal plane, tip close to basal part of fe; small spine (ss) at base of apical part, opposite origin of tibial spine; spatulate lobe (sl) broad, rounded; a small accessory lobe (al) at base of sl; palette (pa) simple, gutter-like, with longitudinal crest (cr) at middle, distally with about twelve brownish blepharochaetae (bp).
DNA barcode
The GenBank accession number of the barcode of the paratype is KC519534 (voucher code CUMZ-D00077).
