Holotype male. No data. Edessa nigrispina Dallas. MNHN ( EH) 25259 ( MNHN) .

Material examined. 1♀ no data ( DRC) .

Measurements. Antennomeres length: 1st: 0.6–0.7; 2nd: 1.2–1.3; 3rd: 1.6–1.7; 4th: 3.2–3.5; 5th: 3.5–3.6; head length: 1.9–2.1; head width: 2.7–2.8; pronotal length: 6.7–8; pronotal width: 10–11.9; scutellum length: 6.7–8; scutellum width: -; abdominal width: 7.4–8.8; total length: 13.6–15.5.

Etymology. Name refers to the shape of humeral angles of the species that resembles big canines.

Diagnosis. Antennae light brown ( Fig. 2 D). Humeral angles very projected, apices acute, covered with a large black spot which continues on ventral surface of thorax ( Figs. 1 D, 2 D). Scutellum with shallow and brownish punctation on anterior region, deep and black on posterior region ( Fig. 1 D). Corium with veins thick, connected with a big spot and almost forming a “Y” ( Fig. 1 D). All segments of connexivum with black stripes on anterior and posterior margin and yellow stripe on medial region; distal margin of segments III-VI with yellow calloused area ( Fig. 1 D). Ventral surface yellow; region between segments very dark ( Fig. 2 D). Propleura with black lines around the base of procoxae ( Fig. 2 D). Area of evaporatorium mostly dark brown ( Fig. 2 D). Legs yellowish to light brown; distal third of meso and hind femora black ( Fig. 2 D). Male: parameres spearhead-shaped, narrow, dorsally directed, margins and apex black ( Fig. 7 D, E); ventral surface of pygophore with a longitudinal dark brown spot ( Fig. 7 B). Female genital plates: margins of all genital plates covered by black to brownish stripes, except valvifers IX ( Fig. 7 F); valvifers VIII distal margins straight and sloping; mesial borders “V” shaped; medial excavation narrow ( Fig. 7 F).

Description. Head. Apex of mandibular plates with a small black spot; lateral margins yellow ( Figs. 2 D, 1 D). Apex of clypeus slightly yellowish ( Fig. 1 D). Antennal segments formula: IV>V>III>II>I.

Thorax. Pronotum green with shallow and brown punctation ( Fig. 1 D). Corium lateral margins yellow ( Fig. 1 D). Membrane of hemelytra dark brown ( Fig. 1 D). Metasternal process elevated anteriorly; anterior arms wide, rounded apices, receiving only the last rostral segment ( Fig. 7 C).

Abdomen. Distal part of seventh abdominal segment with black spot covering almost ½ of the segment ( Fig. 1 D). Region between the abdominal segments and pseudosutures connected by dark spots surrounding spiracles ( Fig. 2 D).

Male ( Fig. 7 A, B, D, E). Pygophore. Superior process of the genital cup subtriangular, anterior part narrow with sinuous margins and posterior part wide; visible in dorsal view ( Fig. 7 A, D, E). Proctiger slightly excavated on laterals, excavation with short setae; dorsal face delimited distally by a small carina; posterior face triangular ( Fig. 7 D, E). Ventral rim with bottom of the excavation flat; with medial dark spot ( Fig. 7 B, D, E).

Female ( Fig. 7 F). Valvifers VIII strongly punctate in medial region and setose; margin of valvulae VIII visible; slightly projected towards the base of laterotergites IX ( Fig. 7 F). Valvifers IX very setose, base concave ( Fig. 7 F). Laterotergites IX slightly swollen, very setose; below the level of seventh segment ( Fig. 7 F).

Comments. The label attached to the holotype identifies it as Edessa nigrispina Dallas 1851 . However, the type of E. nigrispina was examined by Fernandes in the collection of the BMNH and is clearly another species. O. dracula sp. n. shares with O. rondoniensis sp. n. and O. maculatus sp. n. the following characteristics: big dark spots on the ventral surface of humeral angles, area of the evaporatorium, distal part of femora, apices of the seventh abdominal segment, ventral surface of the pygophore, laterotergites IX clearly below the level of abdominal segment VII ( Figs. 2 D, E, H, 7 F, 11 F); and the drawn of the veins of hemelytra ( Fig. 1 D, E, H). O. dracula sp. n. can be differentiated from the other species by the shape and size of the humeral angles, clearly the biggest of the genus ( Fig. 1 D).

Distribution. Unknown.
