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 ). Abdomen elongated, dorsum brown to dark brown, dotted, covered with sparse scale-like setae, with several arc-shaped dotted lines posteriorly; venter colored as dorsum, with longitudinal, yellow-brown dotted lines ( Fig. 3C, E ).

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 ).
