Type material.

Holotype ♂ (IZCAS-Ar42615), China: Yunnan: Xishuangbanna, Mengla County, Menglun Town, XTBG, Grove (21°53.84'N, 101°16.48'E, ca. 550 m), 10.v.2019, H. Yu leg. Paratype 1♂ (IZCAS-Ar42616), same data as holotype.

Etymology.

The species name is a patronym in honor of Prof. Jerzy Prószyński (Warsaw, Poland), who has made significant contributions to the taxonomy of salticid spiders; noun (name) in genitive case.

Diagnosis.

Nandicius proszynskii sp. nov. can be easily distinguished from any congeners by the presence of a disto-retrolateral femoral apophysis and a short retrolateral tibial apophysis, which is shorter than the dorsal tibial apophysis vs. lacking a femoral apophysis and with a retrolateral tibial apophysis longer than the dorsal tibial apophysis.

Description.

Male (Figs 10 , 11 ). Total length 2.75. Carapace 1.46 long, 0.98 wide. Abdomen 1.44 long, 0.83 wide. Clypeus 0.01 high. Eye sizes and inter-distances: AME 0.24, ALE 0.14, PLE 0.13, AERW 0.76, PERW 0.82, EFL 0.63. Legs: I 2.09 (0.63, 0.85, 0.37, 0.24); II 1.61 (0.51, 0.59, 0.27, 0.24); III 1.71 (0.54, 0.59, 0.34, 0.24); IV 2.24 (0.76, 0.83, 0.41, 0.24). Carapace yellow to dark brown, slightly narrowed anteromedially, covered by dense, white and brown setae. Fovea indistinct. Chelicerae yellow, with 1 retromarginal tooth and 2 promarginal teeth. Endites yellow to pale brown. Labium dark brown, linguiform. Sternum yellow, mingled with green-brown, with white setae. Legs pale yellow to yellow except femora I dark brown. Abdomen elongated, dorsum pale yellow laterally, with an irregular, longitudinal, green-brown stripe over entire surface; venter pale yellow laterally, brown medially, with pair of dotted lines.

Palp (Fig. 10A-D ): femur about 2.5 times longer than wide, with digitiform disto-retrolateral apophysis; tibia wider than long, with short, blunt retrolateral apophysis, and a lobe-shaped dorsal apophysis; cymbium about 1.8 times longer than wide in ventral view, with a swollen baso-retrolateral process; bulb inflated, with a flat, disto-retrolateral tegular bump; embolus sclerotized, originating at ~11 o’clock position of bulb, tapered, slightly curved to a pointed tip, directed retrolaterally.

Female. Unknown.

Distribution.

Known only from the type locality in Yunnan, China.
