Aamunops noono sp. n.

Figs. 57 – 69

Types. Holotype male. MEXICO: Veracruz, Atotonilco de Calcahualco, 15 km away from the Pico de Orizaba Volcano (Plot II, 19°8’30.2” N, 97°12’21.5” W, elev. 2,388 m), oak forest, leaf litter, collected with pitfall traps, 21-30 May 2012 ( CNAN-T01487 ).

Etymology. The species epithet, a noun in apposition is taken from the “Popoluca de la Sierra” word for mushroom.

Diagnosis. Aamunops noono sp. n. can be distinguished from all other Aamunops species by having a short embolus with small denticles on the tip ( Fig. 68 ) and by the minute crista on the anterior metatarsi ( Figs. 65, 66 ).

Description. Male (Holotype). Total length 4.00. Cephalothorax 1.70 long, 1.20 wide. Sternum 0.44 long, 0.34 wide. Legs: I 4.44 (1.40) (0.70) (1.10) (0.80) (0.44); II 4.12 (1.22) (0.66) (1.00) (0.80) (0.44); III 3.58 (1.04) (0.50) (0.80) (0.80) (0.44); IV 5.26 (1.46) (0.60) (1.26) (1.38) (0.56). Carapace, sternum, chelicerae, labium, orange ( Figs. 57–59, 60 ). Palps and legs light orange; coxae and trochanters lighter ( Fig. 58 ). Endites pale orange, anterior margin lighter ( Fig. 61 ). Abdomen dorsal pattern light gray, ventral surface whitish ( Figs. 57, 59 ). Anal tubercle and spinnerets pale orange. Crista minute, occupying the most distal portion of the metatarsus ventral surface ( Figs. 65, 66 ). Paired claws with seven teeth ( Fig. 67 ). PLS longer than PMS. Prolateral brush of palpal tibia with six setae ( Fig. 69 ); bulb globose, spherical; spermatic duct with a minute, hyaline process ( Fig. 68 ); embolus short, bent, with a wide base ( Figs. 63 , 68 ); tip sharped, with small denticles on the inner margin ( Fig. 68 ).

Female: unknown.

Natural history. The only known specimen was caught in the leaf litter of a Quercus forest fragment.

Distribution. Known only from the type locality ( Fig. 83 ).
