Figs 2–3, 56

Diagnosis

The male of Heliophanoides proszynskii sp. nov. resembles that of H. tengchongensis (Lei & Peng 2013) comb. nov. in having the slender RTA and platelike DTA, but differs by the RTA, which is curved medially and more than two-thirds the cymbial length in retrolateral view (Fig. 2B), but straight and just one-third the cymbial length in H. tengchongensis (Lei & Peng 2013: fig. 8b). The female can be easily distinguished from other congeners by having the sub-linguiform base plate and lacking the concave epigynal structure (Fig. 3A), whereas having a square base plate and a pair of lateral concave epigynal structures in others (Prószyński 1992: figs 49, 53–54; Lei & Peng 2013: fig. 8d–e).

Etymology

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

Chelicerae brownish-yellow, with one retromarginal tooth and two promarginal teeth (Fig. 3F–G). Legs I dark brown except tarsi yellow; others yellow-brown to brown, somewhat mingled with green except metatarsi and tarsi yellow (Fig. 3C).

PALP. Tibia wider than long, with tapered RTA more than two-thirds the cymbial length, and slightly curved to pointed tip directed towards about 10 o’clock position in retrolateral view, and with straight, platelike DTA; bulb longer than wide, with medio-retrolaterally located, sub-triangular tegular bump; lamellar process small, with arc-shaped margin; embolus originates from apical edge of bulb, slightly shorter than the DTA, sclerotized, curved retrolaterally and blunt apically (Fig. 2).

Female (paratype, TRU-JS 0058)

MEASUREMENTS. Total length 3.31. Carapace 1.41 long, 1.23 wide. Abdomen 2.19 long, 1.59 wide. Eye sizes and inter-distances: AME 0.34, ALE 0.18, PLE 0.16, AERW 1.06, PERW 1.11, EFL 0.71.
