Type material. Holotype: male, PAPUA NEW GUINEA: Eastern Highlands Province: Mt. Gahavisuka Provincial Park , 6.016° S, 145.417° E to 6.017° S, 145.416° E, elev. 2450–2490 m a.s.l., 2 August 2008, coll. W. Maddison, WPM#08-027 ( UBC-SEM AR00103 ) GoogleMaps . Paratypes: 4 males in three vials, same data as holotype GoogleMaps .

Etymology. The specific epithet is a patronym in honor of Dr. Tamás Szű ts, who has contributed much to the taxonomy of this genus.

Diagnosis. Resembles Thorelliola dumicola Berry, Beatty & Prószyṅski, 1997 in the absence of macrosetae on the tibia of male palp, but differs by the presence of a truncus on the male clypeus equipped with two ”horns”, and the short embolus ( Figs 245–246). Can also be distinguished from other species that have the clypeal truncus by the combination of following chatacters: embolus is short; retrolateral sperm duct loop occupies about half of the bulb width; tibia of male palp lacks prolateral macroseta ( Figs 245–246).

Description. Male (holotype, UBC-SEM AR00103). Carapace length 2.2 (variation 1.8–2.3, n=5); abdomen length 2.3. Truncus in the middle of clypeus and armed with two horn-like macrosetae with bases fused together. Chelicera ( Figs 247–248): dark brown to red brown; with two promarginal teeth and one retromarginal tooth of six or seven cusps; with a small projection on the front surface. Palp ( Figs 245–246): dark brown. Embolus very short; sperm duct loop occupying about half of the bulb width. Macroseta absent on the prolateral side of palpal tibia. Tibia of palp with a clump of long setae retrolaterally in front of retrolateral tibial apophysis. Retrolateral tibial apophysis relatively thick. Tibia and metatarsus of first leg with three pairs of ventral macrosetae each. Measurements of legs: I 6.3, II 4.6, III 4.9, IV 5.2. Color in alcohol ( Fig. 244): carapace dark brown, area around fovea yellow brown; abdomen gray brown, with many irregular sandy yellow speckles, posterior part with 3–4 parallel yellowish bands; first two pairs of legs dark brown proximally and sandy yellow distally, last two pairs of legs gray brown proximally and sandy yellow distally.
