Diagnosis. Frons slightly impressed medially ( Fig. 4 View FIGURE 4 B); pronotum with weak lateral punctures, absent on posterior third ( Figs 1 View FIGURE 1 B, 3B); outer subhumeral stria present on posterior half ( Fig. 3 View FIGURE 3 B); apical elytral stria present ( Fig. 5 View FIGURE 5 B); propygidium with strong punctures on anterior and lateral margins, smooth on remainder of the structure ( Fig. 5 View FIGURE 5 B).
Description. Size range: length (pronotum + elytra): 7–7.4 mm, width (humeral region): 6.3–6.6 mm. Body form: body oval, convex. Head: frons about 2x wider than long, covered with weak punctures, slightly impressed medially; frontal stria complete, slightly curved inward. Pronotum: without foveae; lateral pronotal stria complete, slightly curved towards middle of posterior margin; lateral punctures of pronotum usually weak, slightly stronger on anterior angles, sometimes absent on posterior third. Elytra: outer subhumeral stria continuous, present on posterior half; inner subhumeral stria absent; first dorsal elytral stria weakly indicated, slightly shortened on anterior tenth; second dorsal elytral stria weakly indicated, shortened on anterior and posterior sixth; third dorsal elytral stria weakly indicated on anterior half; fourth and fifth dorsal elytral striae absent; sutural elytral stria absent; apical elytral stria complete. Prosternum: prosternal lobe rounded, marginal prosternal stria shortened medially; lateral punctures of prosternal keel present; prosternal keel with weak punctures medially, carinal striae of prosternal keel absent; prosternal process rounded. Mesoventrite: marginal mesoventral stria of mesoventrite interrupted, starting slightly before the angles medially; lateral punctures absent; mesometaventral stria absent, mesometaventral suture slightly curved towards prosternum medially. Abdomen: propygidium with strong punctures on anterior and lateral margins, smooth on the remainder of the structure, without impressions or foveae on posterior half, on each side; pygidial punctures strong on anterior third, weaker towards posterior margin, absent on posterior fourth, with a superficial fovea on anterior angles. Male genitalia ( Figs 8 View FIGURE 8 A–E): eighth tergite subrectangular, with a pair of long anterolateral projections, one on each side, posterior angles rounded, posterior margin straight; eighth sternite with a large basal emargination; ninth tergite without apical emargination; tenth tergite with interrupted sclerotization, with one sclerotized area on each side, sides rounded; aedeagus elongated, base of parameres straight in dorsal view, slightly emarginated in ventral view, apex truncated, sided rounded, slender on apex.
Distribution. Dominican Republic.
Etymology. This species is named in apposition (nominative singular) from classical form, after a great Odonata researcher, Dr. Angelo Barbosa Monteiro Machado, here honored for his 80th birthday.
Remarks. This species is diagnosed under O. kovariki sp. nov. The punctures on the propygidium of O. angelo sp. nov. are somewhat variable. In a few specimens there are a few punctures medially on anterior margin, while, in others the punctures are limited to the sides of anterior margin and lateral angles. The second dorsal elytral stria is also variable, absent in most cases and sometimes indicated by a few weak punctures on posterior third.
