Goeldia chinipensis Leech, 1972

( Figs 8 ; 24 )

Goeldia chinipensis Leech, 1972: 104 , figs 187–188 (holotype ♂ and paratype ♂ from mountain near Milpillas (~ 27°17’N 108°35’W), elev. 2000 m, Chinipas, Chihuahua, México, 1.II.1969, V. D. Roth coll, both deposited in AMNH, paratype examined).

Additional Material Examined. None.

Diagnosis. Goeldia chinipensis differs from other species by the tegular process finger-shaped, with base larger than the apex ( Fig. 8A ); by the thick and distally constricted patellar apophysis ( Fig.7B–C ) and torsion of the palpal tibia ( Fig. 8C ).

Description. Male (paratype, AMNH). Coloration: carapace, chelicerae, endites, labium, sternum, and femora dark brown; other leg segments yellowish-brown. Opisthosoma black. Total length 3.52. Carapace: length 1.84, width 1.68, height 1.04. Opisthosoma: length 1.64, width 1.24. Clypeus height: 0.12 high. Eye diameters and interdistances: AME 0.08; ALE 0.11; PME 0.08; PLE 0.08; AME–AME 0.11; AME–ALE 0.13; ALE–PLE 0.09; PLE–PME 0.19; PME–PME 0.14; PME–AME 0.12. Paturon: 1.0 long. Leg measurements: I: femur 1.52/ patella 0.66/ tibia 1.28/ metatarsus 1.42/ tarsus 0.80/ total 5.68; II: 1.32/ 0.70/ 1.10/ 1.16/ 0.62/ 4.90; III: 1.20/ 0.60/ 0.80/ 0.96/ 0.52/ 4.08; IV: 1.42/ 0.50/ 1.12/ 1.20/ 0.60/ 4.84. Leg formula 1243. Leg spination: femur I p1ap; II p1ap; tibia I v1-3-1m-2(1r- 1m)-2(1m-1p); III v1sa, p1sa, r1sa, IV v1-2-1- 1m; metatarsus I p1ap, r1ap, v1apm; II p1ap, r1ap, v1map; III v2-1r- 1m, r1ap, p1-1d-1ap; IV v2-3-2- 1m; r1ap, p0-1-1ap. Patellar apophysis thick and pointed ( Fig. 8C ). Tibial apophysis projected to prolateral side due to tibial torsion ( Fig. 8C ). MLT reduced and apex completely membranous ( Fig. 8C ). Tegular process shaped as depicted ( Fig. 8A ). Pars pendula thickening far from the tip of the embolus ( Fig. 8D ). Spermatic duct partially bent ( Fig. 8A ).

Female: Unknown.

Variation. Unknown.

Distribution. Only known from the type locality: Chinipas, State of Chihuahua, Mexico ( Fig. 24 ).
