Figures 233–249

TYPES: Male holotype, female allotype, and male paratype taken at an elevation of 1150 m in Khao Yai National Park , Pak Chong District, Nakhon Ratchasima, Thailand (Oct. 24, 1997; P. Schwendinger), deposited in MHNG (PBI_OON 15505) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Both sexes have about five transverse ridges on the scutopedicel region, all medially interrupted (figs. 235, 245). The tip of the embolus is darkened and directed prolaterally, and the conductor is subdistally expanded (figs. 237–243); the squiggled anterior receptaculum is relatively short, and the basal part of the T-shaped anterior process is long, with a bulbous dorsal expansion (figs. 248, 249).

MALE (PBI_OON 15505, figs. 233–243): Total length 1.76. Carapace pale orange, elevated portion of pars cephalica finely reticulate, sides finely reticulate. Sternum pale orange, finely reticulate. Mouthparts pale orange, endites distally narrowed into rectangle. Abdomen without dark markings. Scutopedicel region with five transverse ridges, all interrupted at middle. Dorsal scutum pale orange, reticulate, covering full length of abdomen, no soft tissue visible from above. Postepigastric scutum pale orange, covering about ¾ of abdomen length. Embolus with darkened, sinuous tip, directed prolaterally, conductor expanded near tip.

FEMALE (PBI_OON 15505, figs. 244–249): Total length 2.24. Elevated portion of pars cephalica smooth. Abdomen dorsum with scattered dark markings. Dorsal scutum covering most of abdomen length, width. Postepigastric scutum short, almost rectangular, covering about 2/3 of abdomen length. Squiggled portion of anterior receptaculum relatively short, basal part of T-shaped sclerite long, with bulbous dorsal expansion.
