DIAGNOSIS: Specimens of
N. fea
can be differentiated from other large
Nanometa
species by the following combination of characters: tibia I ventral surface with small and thick macrosetae (fig. 15C), CEBP with only one large sclerotized apophysis, CEMP a triangular cuticular projection, tip separated from the CEMP and located on the cymbium retrolateral edge (figs. 15G, 17A, B). Conductor tip hook shaped and heavily sclerotized (figs. 15E, G, I, 17A).
DESCRIPTION: Male (
holotype
, TEAU013) total length 4.1. Cephalothorax length 1.9, width 1.5. Clypeus height 1.6 AME diameter. Cuticle coloration dark brown (probably due to preservation artifacts) (fig. 15B). Eyes subequal in size, lateral smaller. Sternum dark brown. Cheliceral promargin and retromargin teeth not observed due to state of specimen preservation. Abdomen dorsum background dark yellow, without guanine patches and a posterior black band (fig. 15B). Stridulatory organ along the anterior booklung edge, coxa IV not observed with SEM. Male pedipalp as described in the diagnosis.
ETYMOLOGY: The species epithet is taken from the feminine Spanish word for ugly,
fea
, and it refers to the poor preservation state of the only known specimen.
DISTRIBUTION:

(fig. 37C).
MATERIAL EXAMINED: No additional material examined.
