description: <i>Oronoqua orellana</i> sp. n. http://zoobank.org/7 D01359 B-84B8- 400B-A1AB-B006345B709C (Figs. 1–3, 7–9, 13–16, 23–29, 38–39) Diagnosis.—A pale species. Forewing reticulation mostly restricted to distal half. Aedeagal hooks elongate, each with lateral projection near midlength followed by lateral serrations. Ventrolateral surface of anal tube (in lateral view) bearing a distal short concavity; in dorsal view, caudal margin concave. Description. <i>—Coloration:</i> Generally yellowish light brown (Figs. 1, 2). Lateral margins of metope (<i>~</i> frons) and coryphe (<i>~</i> vertex) dark brown. Coryphe with brown to dark brown longitudinal stripes besides of median line (Fig. 8). Fore wings transparent or matte, with yellowish light brown veins (Figs. 1–3). Hind wings transparent, with yellowish or light brown veins. Outside apices of fore femora each with dark brown spot. Apices of leg spines and dorsolateral plates of arolium of pretarsus black. Claws brown to dark brown or black. Arolium whitish. Abdomen yellowish light brown. <i>Structure:</i> Total length (from head apex to apex of wings, n=2, unless otherwise indicated), males – 9.4–9.5 mm; females – 11.0–12.0 mm. Body length (no wings) males – 6.5–6.5 mm; females –7.3–7.5 mm. Wing length – 7.5–9.9 (n = 4). Head projected in front of eyes for about width of eye, distally angulate, with apical corners turned up (in lateral view) (Figs. 2, 9). Metope (Fig. 7) long and narrow, rhomboid, widest near level of antennae; lateral margins foliate to frontoclypeal suture and turned perpendicular to metope plane. Dorsal (upper) margin of metope strongly concave. Median carina distinct dorsally, obsolete before frontoclypeal suture; sublateral carinae visible dorsad, running closely to median carina near lower level of eyes. Frontoclypeal suture distinct, nearly horizontal. Post- and anteclypeus with smooth median carina. Ocelli rudimentary. Antennae robust, scape very short (wider than long), pedicel elongate bearing rows of sensory plate organs. Rostrum reaching hind coxae, with long 3 rd segment, equal in length to second one, not narrowing apically. Coryphe (Fig. 8) long and narrow, shallowly rhomboid, 2 times as long as widest point, with lateral margins foliate and diverging subapically; posterior margin obtusely angularly (nearly straight) concave, anterior margin carinate, convex. Pronotum short (Fig. 8; half-length of coryphe at midline), anterior margin abruptly convex medially, acutely angulated; median carina weak, anterior marginal carinae strong following contour of eyes extending laterally to reach caudal margin. Paranotal lobes wide and foliate, with keel behind eyes. Mesonotum large and long, median carina weak, laterally enclosed by raised keels (obsolete caudally) creating shallow median valley; lateral carinae distinct, arched, appearing anteriorly to meet medially, becoming obsolete in posterior half of mesonotum. Fore wings well developed, broadly rounded distally, exceeding abdomen by one-third wing length (Fig. 1). Fore wings with narrow hypocostal plate and cross venation developed only in apical half of the wing. Clavus of fore wing open, about 4/5 as long as whole wing. Basal cell large, elongated oval. Precostal field with 5–12 veins (Fig. 3). Fore wing vein sequence: R 2, furcating closely to basal cell; ir 6–10; r–m 3–7; M 3, first furcation near wing middle, secondary divisions subapically; im 4–6; mcua 4–6; CuA 1; cup–pcu 3–4; Pcu and A 1 join near clavus middle. Hind wings slightly shorter than fore wings. Hindwing sequence (Fig. 23): c-r 2; R 3, firstly furcating below coupling lobe, posterior branch furcating apically; ir 1; r-m 2; M 2, furcating apically; m-cua 2; CuA 3, firstly furcating after coupling lobe, anterior branch furcating apically; icua 1; cua-cup 4; CuP 1; cup-pcu 3; Pcu 2, furcating apically; pcu-a 1 3; A 1 2; A 2 2. Hind tibia with 2 lateral spines (3 in some females, Fig. 13); 6–7 apical spines (arranged 2+4– 5, 2 outer spines larger than others, the two legs are symmetrical mirror images) (Fig. 14). First and second metatarsomeres subequal in length, each distally dilated to enclose succeeding tarsomere (Fig. 16). First metatarsomere with 2 latero-apical and 5–6 intermediate spines (Fig. 14). Second metatarsomere with 2 latero-apical spines and prominent median pad, ventral surface covered by long setae (Fig. 15). Arolium of pretarsus wide, not reaching apices of claws (in dorsal view), with concave posterior margin (Fig. 16). Each claw with 4 long setae. <i>Male terminalia</i> (Figs. 24–29): Pygofer approximately rectangular in lateral view, with concave anterior and convex hind margins (Fig. 24). Phallobase strongly curved upward, horseshoe-shaped (in lateral view), dorso-apically poorly sclerotized and may expand to become spherical (Figs. 24, 26). Ventral phallobase lobe short and wide, slightly enlarged subapically, rounded, not reaching apical margins of dorsolateral lobes (Fig. 27). Aedeagus with long ventral hooks, 2/3 as long as aedeagus, directed basally, acuminate apically, each with short lateral projection near middle and with serrate outer margin distad of lateral process. Apical aedeagal processes visible above the phallobase (lateral view), wide at the level of ventral phallobase lobe margin, narrow apically (Figs. 26, 27, <i>aep</i>). Connective with large cup-like apodeme (Fig. 26, <i>cp</i>). Gonostylus massive, with convex hind margin and widely rounded caudo-dorsal angle (Fig. 28). Capitulum of gonostylus on distinct neck, with marginal hump below capitulum (in lateral view). Capitulum long, slightly enlarged apically (in dorsal view) (Fig. 25). Anal tube large, long and wide, nearly oval (in dorsal view) (Fig. 29), with ventral margins sinuate, deeply concave subapically (in lateral view) (Fig. 24); apex concave (in dorsal view, <i>ac</i>). Anal column long, nearly half as long as anal tube. <i>Female terminalia:</i> Sternum VII with deeply concave hind margin (Fig. 39). Gonoplacs rounded and flat (Fig. 38). Anal tube long, narrowing apically, with weak apical concavity. Anal column long, 0.3 times as long as anal tube, and narrow. Etymology.—The specific name is after the Orellana Province of Ecuador where the type material was collected. Remarks.—The new species is closely related to <i>Oronoqua deina</i> Fennah, 1947 according to fore wing venation and rostrum structure, but clearly differs by male genitalia structure details. <i>Oronoqua orellana</i> sp. n. has the male anal tube concave apically (dorsal view, convex in <i>O. deina</i>) (Fig. 29); its ventral margin (in lateral view) sinuate with short deep subapical concavity and long, shallow proximal concavity (<i>O. deina</i> with ventral concavities deep and subequal) (Fig. 24). Ventral phallobase lobe 1.3 times as long as wide (Fig. 27, vs. 1.7x as long in <i>O. deina</i>, Gnezdilov et al. 2010, figs. 5C, 5D). Ventral aedeagal hooks not curved basally, each hook with short lateral projection near its middle and with serrated outside margin below lateral process (Figs. 26, 27, vs. slightly S-curved in its basal half, without lateral projections and teeth in <i>O. deina</i>, Gnezdilov et al. 2010, fig. 5A). Type material.— Holotype Ơ, Ecuador: “1023 Ecuador Orellana / Erwin Transect / Onkone Gare Camp / Reserva Etnica Waorani ” // “0039 <i>'</i> 25.7 <i>"</i> S 076 27 <i>'</i> 10.8 <i>"</i> W / 11.II.95 T.L.
