Etymology.

The specific epithet daeng means “red” in Thai, alluding to the species’ distinctive red face.

Diagnosis.

Because this is a monotypic genus, the generic diagnosis also applies to Phenasurya daeng .

Description.

Male ( holotype, PSUZC-ARACH-022 ). Measurements: Carapace 3.3 long, 2.5 wide. Abdomen 2.7 long, 1.7 wide. Carapace somewhat broad and relatively high, largely reddish-brown with the ocular area darker brown. Hints of white cheek bands from remaining scales originate at the junction of ALEs and AMEs, traverse just beneath the ocular ridge, and turn slightly upward at the slope of the ocular area. White marginal bands begin at the base of the ALEs and terminate at the posterior edge of the thoracic slope. Clypeus narrow, covered in orange-red hairs. Chelicerae narrow, brown, with one tooth having two tips (one conspicuous, one inconspicuous) on the retrolateral margin and two on the prolateral margin. Legs relatively long, robust, and dark brown. Palp as in Fig. 5 , with an embolus flower-bud-shaped, broad basally and narrowing distally. Tegulum ovoid with a bulky tegular lobe. Abdomen relatively slender with a pale anteroposterior medial band extending only to midway on a dark, glossy integument.

Female ( paratype, PSUZC-ARACH-013 ). Measurements: Carapace 3 long, 2.2 wide; abdomen 3.3 long, 2 wide. Carapace similar in form and pattern to the male but overall paler. Clypeus narrow, sparsely covered with pale hairs. Chelicerae simple, vertical, brown. Legs relatively long, robust, and paler than in the male. Abdomen slender with a pale anteroposterior medial band extending to midway on a dark background, widening laterally near the posterior. Approximately three-quarters towards the posterior, a pair of dark, somewhat glossy patches occur on either side, with one larger patch at the posterior end. Spinnerets long. Epigyne as in Figs 7 , 8 , lacking distinctive pockets; epigastric furrow with a shallow medial notch.

Natural history.

Widely distributed across Thailand (Fig. 21 ) and presently known only from that country, though its occurrence in neighbouring regions is likely given its range within Thailand. It is a vegetation dweller, typically found on low-lying to medium-high vegetation.
