(Figs. 17, 28 E,F, 30 A,B)

Edessa nigroangulata Fernandes et al., 2015: 518 (description).

Holotype: see Fernandes et al. (2015).

During the study of the E. sexdens group of species, we noticed that part of the E. (E.) nigroangulata paratypes were part of another very similar species. The paratypes of E. (E.) nigroangulata are indicated below. The remaining specimens will be described as a new species in a forthcoming article.

Paratypes (n= 5). MÉXICO, Chiapas: 1♀, El Aguacero, nr. Ocozocautla. 26-X-1986, D. Thomas & E. Fisher (TH) . COSTA RICA, Guanacaste: 1♀, Est. Muriciélago, 8km suroeste de Cuajiniquil, 100m, 19–24-IV-1993, F. A. Quesada, CRI001 326849 (L N 320300 347200) (INBio) ; 1♁, Est. Muriciélago, 8km suroeste de Cuajiniquil, 100m, 15-VI–03-VII-1993, Fam. Araya Coronado, #2195. CRI001 836674 (L N 320300 347200) (UFRGS) ; 1♀, La Pacifica, nr. Cañas, 22–26-V-1984, E. Riley, R. Rider & D. Ledoux (DAR) ; 1♁, Centro Ecologico La Pacifica, 17–19-II-1988, D. Thomas, F. Parker ( E. suturara Dallas, 1851 — Comp. w. type Fernandes, JAM 1999) (TH) .

Complementary description. Humeral angle black spot restricted to the angle in dorsal and ventral views (Fig. 28 E,F). Connexival segments with concavities almost entirely covered by trapezoidal black spots separated by a large yellow median spot (Fig. 28 E); spots extending ventrally, subrectangular (Fig. 28 F). Ventral surface. Dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 28 F). Abdomen with spine of third segment acuminated (Fig. 17 G). Male genitalia, superior process of genital cup continuing ventrally in a crenulated low carina without distal dentiform projection (Fig. 17 B,E).

Comments. The original description and comments were presented in Fernandes et al. (2015). Here we present photographs of the holotype in dorsal and ventral views. Also, a plate with photographs of the male and female external genitalia because the original description presented only hand-drawn drawings. This species is similar to E. (E.) electa and E. (E.) nigricornis . See comments of E. (E.) electa and E. (E.) nigricornis .

Distribution (Figs. 30 A,B): MEXICO: Chiapas; COSTA RICA: Guanacaste.
