NERUDIA ATACAMA HUBER, 2000

( FIGS 33 , 34 )

Nerudia atacama Huber, 2000: 87 , figs 333–337. Nerudia atacama – Torres et al., 2015: 5, fig. 4C, D (see N. poma ; misidentification).

Diagnosis: Distinguished from known congeners by shape of procursus ( Fig. 33A–C ; distal half bent towards dorsal; same width over most of its length in lateral view), by bulbal processes ( Fig. 33D–F ; embolus slender tubular), by armature of male chelicerae ( Fig. 33G, H ; frontal apophyses at half length, pointing downwards, with pointed tip in frontal view, set with regular hairs; similar to N. flecha ), and by epigynum and female internal genitalia ( Fig. 34 ; epigynal plate with large posterior indentation, similar to N. flecha ; internal genitalia with large round median ‘receptacle’).

Type material: CHILE – Atacama: • ♂ holotype, re-examined; S of Domeyko, Cuesta Pajonales ; 29.151° S, 70.980° W; 1200 m a.s.l.; 5 Oct. 1992; N. I. Platnick, P. Goloboff, K. Catley leg.; AMNH • 3 ♀♀ paratypes, re-examined; same data as holotype; AMNH .

Other material (not re-examined): CHILE – Atacama: • 1 ♀; Cuesta Pajonales , S of Domeyko; 29.146° S, 70.997° W; 1080 m a.s.l.; 5 Oct. 1992; N. I. Platnick, P. Goloboff, K. Catley leg.; AMNH .

Description (amendments; see Huber 2000): The distinctive male and female structures are shown ( Figs 33 , 34 ) in order to facilitate comparison with the newly described congeners.

Distribution: Known only from the type locality in Atacama, Chile ( Fig. 3 ).
