Diagnosis.—A deeply colored species. Forewing reticulation mostly restricted to its distal half. Aedeagal hooks elongate and distally expanded into a spoon-like structure bearing an asymmetrical distal furcation. Ventro-lateral margin of anal tube (in lateral view) bearing a pair of subequal concavities; in dorsal view, caudal margin concave.

Description.— Coloration: Male. Similar to O. orellana   sp. n., but darker in most respects. General color shades of brown on pale background ( Fig. 4 View Figs ). Lateral carinae and approximate regions of metope (~ frons) and coryphe (~ vertex) near black ( Figs. 10, 11 View Figs ). Preocular fields with dark band from eye to head apex ( Fig. 12 View Figs ). Dorsal (upper) angles of metope, dorsal parts of sublateral carinae and inside margin of ventral portions of lateral carinae dark brown to black ( Figs. 10, 12 View Figs ). Median carina of postclypeus with elongate brown to black spot. Coryphe medially embrowned ( Fig. 11 View Figs ). Rostrum with brown ring apically. Pronotum medially with milky color behind darkened carina, laterally flanked by brown ( Fig. 11 View Figs ). Keel-shaped border between paradiscal fields of pronotum and paranotal lobes dark brown to black ( Fig. 12 View Figs ). Lower margins of paranotal lobes dark brown. Mesonotum color similar to O. orellana   , but more intensely colored – dark brown to black longitudinal stripes tracing median carinae and outside of lateral carinae; whitish markings on apex of scutellum and near tegulae. Fore wings clear, veins light brown to brown, with radius in point of furcation, median in point of first furcation and its anterior branch near wing middle, cubitus anterior near to basal cell, and some transverse veins in apical part of the wing dark brown to black ( Fig. 6 View Figs ). Apical cells embrowned. Clavus below first anal vein and Pcu + A 1 embrowned. Hind wings transparent, with brown veins. Legs with fovea pale, darker on carinae, tibiofemoral joint and on some specimens at apices of tibiae and tarsi. Hind coxae with dark brown areas outside. Fore femora each with dark brown spot subapically on outer side. Middle tibiae with dark brown margins. Hind tibiae with large dark brown spots on apices. Apices of leg spines and dorsolateral plates of arolium of pretarsus black. Apical halves of third tarsomeres dark brown to black. Claws brown to dark brown. Arolium whitish. Abdominal tergites darkened on lateral margins. Abdominal sternites light yellow.

Coloration: Female. Very similar to males. Pygofer with posterior margins shading to dark brown. Anal tube brown. Structure: Total length (from head apex to apex of wings) (n=3 for all measurements except where indicated), males – 11.0–11.1 mm; females – 12.0– 12.7 mm. Body length (no wings) males – 6.2–8.4 mm (n=2); females – 8.6 mm. Wing length, males – 7.1–8.8 mm; females – 10.0 mm. Head distally angulate, projected in front of eyes for about width of eye, with apical corners turned up (in lateral view) ( Fig. 12 View Figs ). Metope long and narrow, rhomboid, widest near level of antennae; lateral margins foliate; dorsally strongly angularly concave ( Fig. 10 View Figs ). Disc of metope convex, median carina keeled from level of antennae to subapical bulla (forming concavity between median carina and lateral margin that is embrowned dorsally); ventrad of antennae, median carina forked, becoming obscure; sublateral carinae visible dorsad, running closely to median carina near lower level of eyes. Frontoclypeal suture nearly straight; post- and anteclypeus triangular, tapering ventrally, with smooth median carina. Ocelli rudimentary (adjacent to anteroventral margin of eye). Antennae robust, scape very short (wider than long, about 1/4–1/ 3 length of pedicel), pedicel more elongate, bulbous, bearing rows of sensory plate organs. Rostrum reaching hind coxae, with terminal (3 rd) segment, equal in length to preceding one; apex of rostrum slightly curved ( Fig. 21 View Figs ). Coryphe long and narrow ( Fig. 11 View Figs ), shallowly rhomboid; anterior margin convex and carinate, disc concave, slightly more than twice as long as widest point; lateral margins foliate, diverging subapically; posterior margin angularly concave. Pronotum short (half-length vertex, 1/3 length of mesonotum at midline), anterior margin medially convex with anterior apex abruptly convex; median carina obsolete, lateral carinae strong, keeled, following curved contour of eyes, extending laterally to paranotal lobes, longitudinally keeled behind eyes, wide and foliate, projected ventrally to below level of antennae. Mesonotum large and elongate, median carina paired, enclosed distally and laterally by lateral keels (obsolete caudally) creating shallow median valley; carinae becoming obsolete posteriorly. Fore wings well developed, broadly rounded distally, exceeding abdomen by one-quarter to one-third of wing length ( Fig. 4 View Figs ). Fore wings with narrow hypocostal plate, cross venation developed only in apical half; clavus about 4/5 as long as wing, Pcu+A 1 of clavus reaching claval fold (CuP). Basal cell distinct, elongated oval. Precostal field with 10–14 veins. Fore wing vein sequence: R 2, furcating closely to basal cell; ir 7–11; r–m 4–6; M 3–4, first furcation before wing midlength, secondary divisions subapically; im 3–5; m–cua 3–5; CuA 1; cup–pcu 2–3. Pcu and A 1 join beyond clavus midlength. Hind wings broad, slightly shorter than fore wings. Hindwing sequence ( Fig. 22 View Figs ): c-r 4; R 2, firstly furcating below coupling lobe; ir 2; r-m 4; M 1; m-cua 4; CuA 3, firstly furcating after coupling lobe, anterior branch furcating apically; icua 1; cua-cup 3; CuP 1; cup-pcu 5; Pcu 2, furcating apically; pcu-a 1 3; A 1 2; A 2 2. Hind tibia with 2 lateral spines ( Fig. 17 View Figs ); 7–9 apical spines, irregularly arranged, 2 outer spines on each side largest. First metatarsomere slightly longer than second one, each distally dilated to enclose succeeding tarsomere ( Figs. 18, 19 View Figs ). First metatarsomere with 2 latero-apical and 5 intermediate spines; second metatarsomere with 2 latero-apical spines and prominent median pad, ventral surface covered by long setae ( Fig. 19 View Figs ).

Male terminalia ( Figs. 30–37 View Figs ): Pygofer approximately rectangular in lateral view, with concave anterior and convex posterior margins ( Fig. 30 View Figs ). Phallobase strongly curved upward, horseshoe-shaped (in lateral view), dorso-apically membranous portion inflating to spherical sac ( Fig. 34 View Figs ). Dorso-lateral phallobase lobes without processes. Ventral margin of each dorso-lateral phallobase lobe deeply and widely concave subapically. Ventral phallobase lobe short and wide, nearly quadrangular, with straight upper margin, far not reaching apical margins of dorsolateral lobes ( Fig. 35 View Figs ). Apical aedeagal processes massive, well visible above phallobase, each with two lobes. Aedeagus with long ventral retrose hooks ( Fig. 35 View Figs ), slightly enlarged apically, emerging at nearly 3 / 4 length of aedeagus, extending retrosely nearly to aedeagal base, hooks straplike, distally expanded into spoonlike structure, asymmetrically bifid with distal and subapical processes (lateral serrations absent; Fig. 33 View Figs ). Each hook with a transverse white spot subapically. Connective with large cup-shaped apodeme. Gonostylus massive, with nearly straight hind margin and right caudo-dorsal angle. Capitulum of gonostylus elongate on long neck (in lateral view), with large lateral tooth ( Fig. 31 View Figs ). Capitulum of gonostylus slightly enlarged apically (in dorsal view) ( Fig. 32 View Figs ). Anal tube large, long and wide, nearly rhomboid in dorsal view, with apical concavity ( Fig. 37 View Figs ); in lateral view sinuate ventrally creating two, approximately equal, deep concavities ( Fig. 30 View Figs ). Anal column nearly half length of anal tube.

Female genitalia: Sternum VII with deeply concave hind margin ( Fig. 41 View Figs ). Gonoplacs truncate and flat with scalloped lateral margins ( Fig. 40 View Figs ). Anal tube long, broad, tapering distally to truncate apex. Anal column about 1/3 length of anal tube.

Etymology.—The specific name ‘ feria   ’ is after the modern Latin word meaning holiday, festival, and is intended as feminine in gender.

Remarks.—Superficially, specimens of Oronoqua feria   sp. n. are darker and more strongly marked than O. orellana   sp. n. (and O. ibisca Gnezdilov, Bonfils, Aberlenc and Basset   ), and are similar to O. deina Fennah   in general appearance. External differences such as coloration ( O. deina   appears to have a pale midventral vitta on the vertex and pronotum, lacking in O. feria   ), but based on currently available specimens, it is unclear whether coloration is fully consistent. Diagnostic differences separating the species include fore wing reticulation (only O. ibisca   possesses reticulation in the fore wing base). The male of O. ibisca   is unknown. Male genitalic structures separating the remaining 3 species include features of the ventral margin of the anal tube in lateral view ( O. deina   and O. feria   sp. n. have 2 subequal concavities, O. orellana   sp. n. has a short, distal concavity); in dorsal view, O. deina   has the apex of the anal tube convex, as opposed to concave in O. orellana   sp. n. and O. feria   sp. n.; and finally differences in the straplike ventral aedeagal hooks: in O. feria   sp. n. parallel sided in lateral view, subapically expanded into a spoon-like, asymmetrically bifid structure; in O. orellana   sp. n. the possess a lateral projection near midlength and are distally serrated for about ½ their remaining length; for O. deina   they are sinuate near midlength.
