Holotype and paratypes: see Fernandes et al. 2015.

The original description and comments were presented in Fernandes et al. (2015). Here are photographs of the holotype and a plate with photographs of the male and female external genitalia, as the original description only includes hand-drawn drawings.

Additional material. COSTA RICA, Heredia: 2♁, Biol. Sta. La Selva, 31-VIII-1998, C. W. & L. B. O’Brien (JEE); 1♀, 5km of Puerto Viejo La Selva Biol. Station, 9-X-2009 (NMPC); 1♀, 5km of Puerto Viejo La Selva Biol. Station, 2-XI-2004 (NMPC).

Diagnose. See Fernandes et al. (2015).

Complementary description: Humeral angles as long as wide (Fig. 24 C); humeral angle black spot restricted to the distal part of the angle in dorsal and ventral views (Fig. 24 C,D). Connexival segments with concavities partially covered by black spots; rounded spots in ventral view (Fig. 24 C,D). Ventral surface. Dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 24 D). Legs with tibiae and tarsi darker than the rest (Fig. 24 D). Abdomen with spine of third segment rounded (Fig. 2 G). Intersegmental areas black, not reaching ventral spots of connexivum (Fig. 24 D). Pseudosutures concolorous with surface (Fig. 24 D). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 2/3 of the surface (Fig. 2 A,B,E). Superior process of genital cup continuing ventrally in a high crenulated carina, ending in a small dentiform projection (Fig. 2 B,E). Anterior half of proctiger brown (Fig. 2 A,B,D,E). Female genitalia, laterotergites VIII with two small dark spots on outer lateral margins (Fig. 2 F).

Comments. This species is unique in the subgenus due to color pattern of the humeral angle which is orange and black (Fig. 24 C,D). The other species of the subgenus that resembles E. (E.) bella is E. (E.) lewisi. Both have a similar distribution (Figs. 31 A, 32 A,B) and size of the body (Figs. 24 C,D, 27 C,D), but the former has the connexival segments with dark spots and corial veins concolorous (Fig. 24 C) and the later has the connexival segments without spots and corial veins creamy (Fig. 27 C), clearly contrasting with the color of the corium (Fig. 27 C).
