Figs 1, 2 View FIGURES 1 – 6. 1, 2

Enna chickeringi Silva, Lise & Carico, 2008: 82 View in CoL , figs 4, 20, 21. Female holotype from Lancetilla, [15°42’N, 87°28’W] Honduras, 19.VII.1929, A. M. Chickering, (MCZ 63821) (examined).

Diagnosis. The males of E. chickeringi Silva, Lise & Carico 2008 resemble those of E. bonaldoi Silva, Lise & Carico 2008 by the shape of the median apophysis (Silva et al. 2008, p. 104, fig. 123), but can be distinguished by the small and laminar dorsal division of the median apophysis (DD) and by the rounded guide (G) of the median apophysis (MA) ( Figs 1, 2 View FIGURES 1 – 6. 1, 2 ).

Description. Male (Puntarenas, Costa Rica, INBio 50912). Total length 6.22. Carapace 3.32 long and 2.82 wide, light brown, dark brown laterally; fovea marked. Clypeus light brown, 0.26 high. Anterior eye row straight, 0.82 wide; posterior recurved 1.58 wide. Eye diameters, interdistances, and median ocular quadrangle: AME 0.16, ALE 0.12, PME 0.20, PLE 0.10; AME-AME 0.14, AME-ALE 0.08, PME-PME 0.52, PME-PLE 0.28, OQA 0.42, OQP 0.90, OQH 0.56. Chelicerae dark brown, frontal face glabrous; promargin and retromargin of fang furrow with three teeth equidistant and equal in size. Sternum yellow, bristly; 1.50 long, 1.54 wide. Labium dark brown, 0.56 long, 0.58 wide. Legs light brown, unmarked, relative length: I-IV-II-III, I – femur 3.73/ tibia-patella 5.47/ metatarsus 3.81/ tarsus 1.66/ total 14.67; II – 3.71/ 5.14/ 3.65/ 1.41/ 13.91; III – 3.07/ 3.81/ 2.90/ 1.07/ 10.85; IV – 3.90/ 4.64/ 4.15/ 1.57/ 14.26. Ventral pairs of macrosetae on tibiae: I-4; II-4; III-3; IV-3. Abdomen, 2.98 long, dark gray, dorsum with three anterior whitish bands and with two pairs of sigilla. Venter yellow, scattered setae. Palpus with a short dorsal division of the median apophysis (DD) ( Fig. 1 View FIGURES 1 – 6. 1, 2 ). Retrolateral tibial apophysis short and with an acute ectal division (ECD) ( Fig. 2 View FIGURES 1 – 6. 1, 2 ).

Material examined. COSTA RICA, Puntarenas: Peninsula de Osa, Puerto Jimenez, rio Agujas [27°71’N, 52°81’W], 1 Ƥ, 14.II.1998, M. Lobo ( INBio 50912).
