Figs. 70 – 80

Types. Holotype male. MEXICO: Veracruz, Xamaticpac de Calcahualco, 23 km away from the Pico de Orizaba Volcano (Plot I, 19°7’34.1” N, 97°4’1.5” W, elev. 1,710 m), oak and tropical wet forest, leaf litter, collected with pitfall traps, 2-11 October 2013 (CNAN-T01488).

Etymology. The species epithet, a noun in apposition taken from the Spanish word confuso and it refers to the phylogenetic uncertainty in the relationships of this species.

Diagnosis. Male pedipalp of Orthonops confuso sp. n. is similar to those of Orthonops ovalis, Orthonops lapanus Gertsch & Mulaik and Orthonops icenoglei Platnick by having a long, proximally curved embolus (Fig. 73, Platnick 1995: figs. 30, 31, 33, 34, 36, 37), differs from these species by having a bent embolus tip (Figs. 73, 76, 80), by the presence of a prolateral brush in the palpal tibia (Fig. 80) and for lacking crista.

Description. Male (Holotype). Total length 2.40. Cephalothorax 1.12 long, 0.86 wide. Sternum 0.80 long, 0.60 wide. Legs: I 2.94 (0.90) (0.50) (0.70) (0.50) (0.34); II 2.72 (0.80) (0.46) (0.62) (0.50) (0.34); III 2.38 (0.70) (0.34) (0.50) (0.50) (0.34); IV 3.46 (0.90) (0.42) (0.80) (0.86) (0.48). Carapace, sternum, chelicerae, and labium light orange (Figs. 70–72, 74). Palps and legs yellowish. Endites, coxae and trochanters pale orange (Fig. 72). Abdomen dorsal pattern light gray, ventral surface whitish (Figs. 70, 72). Anal tubercle and spinnerets pale orange. Crista absent, gladius present, with the most common shape among nopines (Figs. 77, 78). Paired claws with eight teeth (Fig. 79). PLS same size as PMS. Palpal patella shorter than tibia, cup-shaped; tibia slightly excavated ventrally, with a prolateral brush on its distal portion (Figs. 73, 80); cymbium elongated, prolateral and ventral surfaces densely covered with strong, long setae, dorsal surface with a chemoreceptor patch of short, fine setae (Fig. 73); bulb globose, pear-shaped, originating from the proximo-ventral region of the cymbium (Fig. 73); base of embolus wide, about a half the maximum width of bulb, with several folds (Fig. 73); embolus long, bent proximally and distally, protruding from the anterior-distal surface of the bulb, ventrally directed, held in a resting position over the carapace (Figs. 71, 73, 74, 76).
