Description

Scyloxes magna (Bristowe, 1952) comb. n.

Fig. 13A–B

Scytodes magnus Bristowe, 1952: 703, figs 9–10 (one ♂ and several ♀ syntypes from MALAYSIA, Selangor, Kuala Lumpur, Batu Caves [3°14'18.0"N 101°41'00.0"E], November 1930 – January 1931, W.S. Bristowe leg., should be deposited in MNHN, not examined).

Scytodes magna: Brignoli 1976: 159, fig. 55 (♀).

Additional material examined. MALAYSIA: Selangor: 2♀, 1juv., surroundings of Kuala Lumpur, Batu Caves [3°14'18.0"N 101°41'00.0"E], 24 July 1969, R. Pilet leg. (MHNG).

Diagnosis. Scyloxes magna comb. n. resembles S. zhaoi comb. n. (Fig. 13C–H; Wu et al. 2017: figs 16A–F, 17A–E) by the male palp with long, distally coiled embolus and by the female vulva with two pairs of spermathecae on very long stalks. Males are distinguished from the latter species by the cymbium longer than wide, embolus lacking medial twist and gently arched before coil (Bristowe 1952: fig. 10) (vs. cymbium wider than long, embolus medially twisted and strongly arched before coil in S. zhaoi comb. n.). Females are distinguished by the epigyne with reduced sclerotized pre-epigastric fovea (well-developed in S. zhaoi comb. n.) and by the vulva with one pair of spermathecae tubular (Fig. 13B; Bristowe 1952: fig. 10) (vs. both pairs rounded in S. zhaoi comb. n.).

Description. See Bristowe (1952: 703) and Brignoli (1976: 159).

Complementary description. Female (MHNG): habitus as in Fig. 13A. Epigyne: sclerotized pre-epigastric fovea reduced to small bump, separated from each other by almost three times their width. Vulva as in Fig. 13B: outer spermathecae tubular, sinuous; inner spermathecae ovoid on long slightly convoluted stalk.

Distribution. Malaysia (Fig. 17).
