Figs 3A , 8 , 15B

Type material. Male holotype from Costa Rica, Heredia Province, Puerto Viejo de Sarapiquí (10.45, -84.01), 4.VIII.1965, F. Coyle coll., deposited in MCZ 79099. Female paratype from Costa Rica, Heredia Province, Puerto Viejo de Sarapiquí (10.45, -84.01), 2.I.1991, P.R. Graig coll., deposited in CAS.

Etymology. The species name is a toponym in apposition referring to the type locality.

Diagnosis. Males of Kiekie sarapiqui ( Fig. 8 A–B) resemble those of K. sinuatipes ( Fig. 5 A–B) by the shape of the embolus and RTA, but can be distinguished by the shorter and wider median apophysis and narrower conductor. Females of Kiekie sarapiqui ( Fig. 8C ) also resemble those of K. sinuatipes ( Fig. 5C ), but can be distinguished by the shape of the epigynum, with longer median field and shorter lateral projection of the lateral fields. Internally, the copulatory ducts of Kiekie sarapiqui ( Fig. 8D ) fold over itself before they connect to the spermathecae, while in K. sinuatipes ( Fig. 5D ) they exhibit a twist, not covering the spermathecae.
