Diagnosis: Easily distinguished from known congeners by shape of procursus ( Fig. 35A–C View Figure 35 ; short distal element with hooked tip, without membranous part) and by bulbal processes ( Fig. 35D–F View Figure 35 ; embolus much shorter than ventral apophysis); also by armature of male chelicerae ( Fig. 35G, H View Figure 35 ; frontal apophyses pointing downwards, with slightly widened flat tip, set with regular hairs), and by epigynum and female internal genitalia ( Figs 35I View Figure 35 , 36 View Figure 36 ; epigynal plate with large posterior indentation; internal genitalia apparently without or with small median ‘receptacle’).

Type material: CHILE – Coquimbo: • ♂ holotype, 1 ♀ paratype; road to Pascua Lama Mine; approximately 29.445° S, 70.502° W, +/– 6 km; 3000–3280 m a.s.l.; 3 Feb. 2014; A. A. Ojanguren-Affilastro, J. Pizarro-Araya, P. Agusto, R. Botero Trujillo and H. Iuri leg.; MACN Ar 37782.

Etymology: The species epithet flecha (Spanish for ‘arrow’) is taken from Pablo Neruda’s poem ‘Poema 1’; noun in apposition.


Male (holotype). Measurements: Total body length 1.50, carapace width 0.62. Distance PME – PME 80 µm; diameter PME 50 µm; distance PME – ALE 20 µm; distance AME – AME 20 µm; diameter AME 35 µm. Leg 1: 4.57 (1.30 + 0.20 + 1.30 + 1.30 + 0.47), tibia 2: 1.07, tibia 3: 0.90, tibia 4: 1.27; tibia 1 L/d: 19 .

Colour (in ethanol): Prosoma and legs mostly pale ochre-yellow; carapace with light brown Y-mark behind ocular area; legs without dark rings; abdomen monochromous pale-grey.

Body: Habitus similar to N. poma (cf. Fig. 1B View Figure 1 ). Ocular area barely raised. Carapace with indistinct thoracic groove. Clypeus unmodified (only rim slightly more sclerotized than in female). Sternum wider than long (0.44/0.40), with pair of small anterior processes near coxae 1. Abdomen globular.

Chelicerae: As in Figure 35G, H View Figure 35 ; short frontal apophyses set with regular hairs, tips slightly flattened; stridulatory files on low lateral protrusions.

Palps: In general, similar to N. colina (cf. Fig. 4 View Figure 4 ) but femur absolutely and relatively shorter (length/width 1.76) and tibia slightly less strongly enlarged (length/ width 1.13); procursus simple, in lateral view slightly bent towards dorsal, distal part short, with distinctive hooked tip, without membranous element ( Fig. 35A–C View Figure 35 ); genital bulb with weakly curved ventral apophysis distally semi-transparent, embolus much shorter than ventral apophysis ( Fig. 35D–F View Figure 35 ).

Legs: Without spines and curved hairs; with vertical hairs in higher than usual density on tibia 1 only, in two dorsal rows (prolateral and retrolateral); retrolateral trichobothrium of tibia 1 at 64%; prolateral trichobothrium absent on tibia 1; tarsus 1 with ~seven pseudosegments, only distally distinct.

Female: In general, similar to male but sternum without humps and tibia 1 with usual low number of short vertical hairs. Tibia 1: 1.22; carapace width: 0.68. Epigynum ( Fig. 36A View Figure 36 ) anterior plate semi-circular to trapezoidal, with large posterior indentation; posterior plate short but wide. Internal genitalia ( Figs 35I View Figure 35 , 36B– D View Figure 36 ) simple, apparently without or with small median ‘receptacle’.

Distribution: Known only from type locality in Coquimbo, Chile ( Fig. 3 View Figure 3 ).
