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

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 View FIGURE 30 ): MEXICO: Chiapas; COSTA RICA: Guanacaste.
