Type material. Holotype: male, ECUADOR: Esmeraldas: Reserva Canandé, Grd.–Cuckoo Trail, 0.5214– 0.5216 ° N, 79.2049– 79.2045° W, elev. ca. 550 m, 22 August 2011, coll. Piascik & Vega, WPM#11–177 (UBC-SEM AR00139, QCAZ). Paratype: 1 female, ECUADOR: Esmeraldas: Reserva Canandé, Choco Tapa Culo Trail, 0.524– 0.526 ° N, 79.212– 79.213 ° W, elev. 350 m, 21–23 August 2011, coll. Maddison & Vega, WPM#11–173 (UBC-SEM AR00140).

Etymology. The specific epithet is a patronym in honor of Dr. Gitanjali Bodner, who studied the phylogeny of Euophryinae in her PhD thesis.

Diagnosis. Could be recognized by the whitish markings of the thoracic area, and by the female’s contrasting wide yellowish median stripe of the abdomen. Similar to Chapoda angusta in the epigynal form, but differs in the color pattern of the body ( Figs 25–26 ), the narrower embolic spiral and the wider retrolateral sperm duct loop of the male palpal bulb ( Fig. 27 ).

Description. Male (holotype, UBC-SEM AR00139). Carapace length 1.5; abdomen length 1.4. Chelicera: yellow brown to gray brown; promargin with two teeth, retromargin with one tooth. Palp ( Figs 27–28 ): femur dark, other segments yellow brown to light yellow. Proximal tegular lobe distinct; retrolateral sperm duct loop wide; embolus short and slightly curved with the spiral relatively narrow; retrolateral tibial apophysis finger-like; ventral tibial bump obvious. Measurements of legs: I 3.0, II 2.8, III 3.4, IV 3.5. Color in alcohol ( Fig. 25 ): carapace dark brown, middle area and lateral margins with white scales, clypeus also covered with white scales; abdomen anterior margin and lateral margins dark, other areas pale yellow with some gray markings; legs yellowish to dark brown.

Female (paratype, UBC-SEM AR00140). Carapace length 1.6; abdomen length 2.1. Chelicera: with two promarginal teeth and one retromarginal tooth. Measurements of legs: I 3.0, II 2.9, III 3.4, IV 3.9. Epigynum ( Fig. 29 ): window relatively small with a median septum. Vulva ( Fig. 30 ): copulatory duct very short; with a pair of spherical secondary spermathecae; primary spermatheca long and oval. Color in alcohol ( Fig. 26 ): similar to that of male, but carapace with a stripe behind PLEs composed of white scales; abdomen with two lateral dark stripes; legs paler than those of male.

Natural history. Specimens were collected by beating foliage in disturbed forest.
