Figs 10 , 15B

Type material. Male holotype from Costa Rica, Puntarenas Province, Santa Elena (10.31, -84.82), near Monteverde, 20.VI.1998, K.J. Ribardo coll., deposited in CAS. Paratypes: 1 female from Costa Rica, Puntarenas Province, Monteverde (10.28, -84.81), 1450 m.a.s.l., 22.VII.1978, C. L. Craig & P. Klass coll. , deposited in MCZ 30607; 1 male from Costa Rica, Heredia Province, 7–8.V.1987, D. Ubick coll., deposited in CAS ; 1 male from Costa Rica, Heredia Province, Finca de La Selva , 4 km SE of Puerto Viejo de Sarapiquí (10.45 -84.00), 100 m. a.s.l., X. 1981, C.E. Griswold coll. ( CAS) .

Etymology. The specific epithet is a patronym in honor of Dr. Charles E. Griswold, for his friendship and outstanding contributions to arachnology.

Diagnosis. Males of Kiekie griswoldi ( Fig. 10 A–B) can be distinguished from the remaining species of the genus by the elongated and strongly curved RTA, emerging from the retrodorsal area of tibia to ventral direction, and median apophysis distally large and C-shaped in ventral view ( Fig. 10A ). Females of Kiekie griswoldi ( Fig. 10C ) resemble those of K. montanensis (Fig. 9C) by the shape of the copulatory opening, but can be distinguished by the larger base of the median field of the epigynum and the anterior position of short lateral field projections.

Description. Male (holotype, CAS). Total length 16.10. Carapace 8.10 long and 6.10 wide. Clypeus 0.20 high. Eye diameters: AME 0.30, ALE 0.22, PME 0.32, PLE 0.30.

Leg formula 4123. Leg spination: tibia I–II v2-2 -2-2-2, r1-1-0, p1-1-1-0, III–IV v2-2 -2, r1-1, p1-1; metatarsus I–II v2-2 -2, r1-1-0, p-1-1-0, III v2-2 -2, r1-1-1, p1-1-1, IV v2-1 -1-2, r1-1, p1-1. Palp ( Fig. 10 A–B): tibia shorter than cymbium; RTA spine-shaped and elongated; embolus elongated and laminar, with a large base, narrowing to the tip; median apophysis short, rounded and slightly curved prolaterally; conductor with narrow base and large apex, covering the tip of embolus.

Female (MCZ 30607). Total length 17.80. Carapace 7.20 long and 5.50 wide. Clypeus 0.35 high. Eye diameters: AME 0.30, ALE 0.27, PME 0.30, PLE 0.30. Legs measurements: I: femur 5.40/ patella 2.80/ tibia 4.80/ metatarsus 4.30/ tarsus 1.70/ total 19.00; II: 5.20/ 2.60/ 4.50/ 4.00/ 1.50/ 17.80; III: 4.30/ 2.30/ 3.60/ 3.70/ 1.40/ 15.30; IV: 5.80/ 2.40/ 5.20/ 6.10/ 1.70/ 21.20.

Epigynum ( Fig. 10 C–D): median field narrowed anteriorly and large and convex posteriorly, with large copulatory opening. Lateral field hyaline in the copulatory opening area. Copulatory duct laminar and curved. Spermathecae laterally elongated, narrow retrolaterally and rounded prolaterally. Fertilization ducts laminar and curved upward.

Additional material examined. None.

Distribution. Costa Rica, Puntarenas and Heredia Provinces ( Fig. 15C ).
