Thyropygus loxia View in CoL n. sp.

( Figs. 17 View FIGURE 17 A–D, 19D)

Material: HOLOTYPE male THAILAND, Suratthani Province, Thachana district, Tam-Yai Temple, 9° 33ˏ 31˝ N, 99° 10ˏ 26˝ E. 11 October 2008. H. Enghoff, S. Panha, P. Pimvichai and members of Animal Systematics Research Unit leg., ( CUMZ). – Paratypes: 1 female and 2 sub-adult males, same data as holotype ( CUMZ).

Etymology: The name refers to the overlapping lateral processes of the gonopod anterior coxal folds, reminiscent of the bill in the bird genus Loxia (crossbills).

Diagnosis: A species of the opinatus subgroup. Spatulate lobe ( sl) at the apical part of telopodite rounded, spoon-like. Similar in this respect to T. inflexus , T. bearti , T. chelatus , T. cristagalli and T. brachyacanthus . Differs from all other species of the T. opinatus subgroup by having a longitudinal lateral crest ( Fig 17 View FIGURE 17 C, arrow) on the anterior coxal fold ( ac); by having the tip of the lateral process of anterior coxal fold ( alp) crossing over with opposite tip, and by having the median process of posterior coxal fold ( amp) very small.

Description: Adult male with 69 podous rings, no apodous rings. Length ca. 10 cm, width ca. 5.5 mm. Adult female with 58 podous rings, no apodous rings. Length ca. 9 cm, width ca. 6.3 mm. Overall color of living animal ( Fig. 19 View FIGURE 19. A D) brown. Antennae and legs brownish orange.

Gonopods ( Figs. 17 View FIGURE 17 A–E): Anterior coxal fold ( ac) ( Figs. 17 View FIGURE 17 A, C) with a lateral longitudinal crest ( Fig. 17 View FIGURE 17 C, arrow); lateral process ( alp) slender, regularly curved, tip crossing over with tip of opposite side, the two together forming a circle; mesal process ( amp) very small, hump-like. Posterior coxal fold ( pc) ( Fig. 17 View FIGURE 17 B) basally with moderately high lateral paracoxites ( px), distally with two processes: mesal process ( pmp) curving caudad; lateral process ( plp) digitiform, directed distad. Telopodite ( Figs. 16 View FIGURE 16 D–E) leaving coxite between pmp and plp; femoral spine ( fe) very long, curved, in situ resting curving close to pmp; telopodite distally to fe with a small round lobe ( lo) projecting distolaterad; tibial spine ( ti) very long, curving in horizontal plane under fe, in situ resting close to mesal part of fe; spatulate lobe ( sl) basally slender, distally broadly expanded, rounded, spoon-like; palette ( pa) simple, gutter-like, distally with about eight brownish blepharochaetae ( bp).

Distribution ( Fig. 20): Known only from the type locality.
