Type material. Male holotype and female paratype from Mata do Butantan [2 °37'32.14"S, 54°56'7.78"W], Belterra, Pará, Brazil, X.2010, pitfall trap, A.D. Brescovit, F.S. Paula & L.C. Chagas leg., deposited in IBSP 163256. Paratypes: 1 male and 1 female (IBSP 163257) and 1 male and 1 female (MPEG 020246) from APA Aramanaí [2°37'57.96"S, 54°57'44.16"W], Belterra, Pará, Brazil, X.2010, pitfall trap, same collectors.

Etymology. The specific name is a nickname for the natives of Belterra, Pará. In this city there are many plantations of mango trees.

Diagnosis. This species resembles C. alegre in having an elongated embolus (see Platnick 1994, figs. 26, 27), but can be distinguished by the globous bulb with distinct prolateral elevation ( Fig. 8 ), and by the epigynal sclerotizations of the females, which have rounded anterior ends and distinct anterior cylindrical extensions at their anterolateral edges ( Fig. 10 ).

Description. Male (holotype). Prosoma brownish except sternum cream with brown margins. AME on black ocular tubercle. Abdomen grayish. Legs brownish. Total length 3.10. Carapace 1.15 long, 1.05 wide. Femur I 0.95, II 0.9, III 0.8, IV 0.9 long. Four eyes, as in C. testacea (see Platnick 1994, fig. 21); AME dark, separated by their radius (0.06), about 0.03 from ALE; ALE pale, translucid, situated anteriorly, about half as large as AME. Carapace flat, without marginal elevations and ocular ridge. Stridulatory file on lateral surface of chelicerae ( Figs. 2, 3 ). Cheliceral fangs long, with curved tip ( Fig. 1 ). Stridulatory pick triangular, situated at base of palpal femur ( Figs. 6 , 7 ). Tarsal organ capsulate with distinct receptor ( Fig. 4 ). Palpal femur with median dorsal tubercle, embolar base relatively wide, embolus long, shape as in Figs. 7–9 , with slender apex ( Fig. 5 ).

Female (paratype, IBSP 163257). Total length 3.15. Carapace 1.10 long, 1.05 wide. Femur I 1.0, II 1.0, III 0.8, IV 1.0 long. Coloration, eye pattern and carapace as in male. Epigynal sclerotizations as in Fig. 10 .
