Diagnosis

The male of Rhene elongata sp. nov. resembles that of R. habahumpa Barrion & Litsinger, 1995 by lacking the terminal apophysis of the embolic division and having a hook-shaped RTA, but differs in: (1) the embolic base being slightly lower than the anteriorl-most edge of bulb in ventral view ( Fig. 38B ), whereas distinctly higher than the anteriorl-most edge of bulb in R. habahumpa ( Prószyński 2009: fig. 41); (2) the RTA being acutely narrowed posteromedially in retrolateral view ( Fig. 38C ), whereas tapered in R. habahumpa ( Prószyński 2009: fig. 46). The female resembles that of R. setipes Żabka, 1985 in the epigynal structure, but it can be easily distinguished by the abdomen, which is more than two times as long as wide ( Fig. 39C ), whereas slightly longer than wide in R. setipes ( Tanikawa 1993: fig. 8).

Etymology

The specific name comes from the Latin word ‘ elongata ’, which means ‘elongated’ and refers to the species having an elongated abdomen; adjective.

Chelicerae red-brown, with one retromarginal tooth and two promarginal teeth, covered by sparse white scale-like setae on anterior surfaces ( Fig. 39F–G ). Leg I strongest, red-brown to dark brown except tarsi yellow, with inflated femora, and bearing dense brown setae on venter of patellae and tibiae ( Fig. 39H ); other legs pale yellow. Abdomen elongated, dorsum yellow to yellow-brown, with several irregular transverse red-brown bands separated by yellow stripes; venter yellow, somewhat mingled with green, with small brown dots ( Fig. 39D–E ).

PALP. Tibia wider than long, with hook-shaped retrolateral apophysis, acutely narrowed medially and pointed apically in retrolateral view; bulb inflated, with sperm duct curved into S-shape retrolaterally; embolus originating from median of anterior edge of bulb, slightly curved medially and blunt apically ( Fig. 38A–C ).
