description: Papaverellus aureocingulatus Artigas & Vieira sp. nov.
Diagnosis. Similar in general appearance and vestiture to species of Eicherax Bigot, 1857. Aedeagus long, slender, ending in 2 long prongs (Fig. 13). Spermathecae long, placed in between the 2 long arms of the genital fork; 2 spherical capsules with long capsular and expulsory ducts (Fig. 18); common duct long, thick, shorter than primary oviducts. Spermathecae (Fig. 18) similar to Eraxasilus luctuosus (Macquart, 1838) (fig. 339 in Papavero et al., 2009).
Description. Holotype male. Head. Ocellar triangle dark, with few, short, black setae; postocular area with black macrosetae and golden setae on dorsal 1/2; scape dark brown; pedicel, postpedicel and stylus light brown; antennae long (Fig. 4); scape twice as long as pedicel; postpedicel 2.5 times as long as pedicel (Fig. 4); stylus with 2 elements (Fig. 4), almost 1.5 times as long as postpedicel (Fig. 4); apex of stylus bare (Fig. 4); 5 black postocular macrosetae on each side of head; frons golden tomentose laterally and brown tomentose on median region; face golden tomentose; face and frons in frontal view roughly triangular in shape (Fig. 2); face widening toward subcranial margin, in lateral view (Fig. 2); face in lateral view produced beyond eye margin over lower 1/2 (Fig. 3) with sparse black macrosetae dorsally, directed anteriorly, ventral 1/2 of facial swelling with yellow macrosetae directed anteriorly and ventrally, more dense towards oral margin. Palpus with long, black macrosetae; proboscis black, yellow setose.
Thorax. Four black antepronotal macrosetae; propleura and mesopleura tumid, golden, setae or macrosetae absent; mesonotum black with dark brown areas surrounded by silvery lines; metapleura tumid, silver; postpronotal lobe with short scattered, yellow setae; 2 notopleural macrosetae; 1 supra-alar macroseta; 2 postalar macrosetae; 3 pairs of postsutural dorsocentral macrosetae; anatergum asetose; katatergal macrosetae yellowish; setae on posterior meron + metanepisternum yellowish; scutellum tumid, silvery, without groove on posterior border; 2 black and long apical scutellar macrosetae; discal scutellar setae yellowish.
Wings (Fig. 5). Hyaline, veins brown; cell r1 close before wing margin; R4 without recurrent vein; R4 ending before tip of wing, and R5 after; bifurcation of veins R4 and R5 before apex of discal cell; cell m3 close; microtrichia on posterior wing margin arranged in a single plane.
Legs. Coxae gray, tumid, similar to pleura, fore and middle coxae with white setae dorsally. Femora shining black (Fig. 1); fore femora with golden setae ventrally, middle femora with strong, black macrosetae ventrally and anteriorly; hind femora with 2–3 black anterior macrosetae, 5 black macrosetae anteroventrally and 1 black preapical anterodorsal and 1 black preapical posterodorsal macroseta; tibiae yellow, except for a brown stripe anteriorly (Fig. 1); fore tibia with 2 black anterodorsally and 5 black setae posterodorsally; 3 long black macrosetae and yellow setae posteriorly; middle tibiae with 3 long setae posteriorly; hind tibiae with 2–3 black setae anterodorsally; tarsus light brown with black setae. Claws black, pulvilli yellow.
Abdomen. Silver with reflections dorsally, tumid laterally (Fig. 1). Segments setose laterally (Fig. 1).
Terminalia. Shiny black, black and yellow setose, rotated at a 45º angle with abdomen (Figs. 1, 7). Epandrium flat ventrally, similar to the shape a split hoof of goat (Fig. 7). Epandrium globose basally, pointed apically (Fig. 1); basal 1/2 of gonocoxite elongate apically (Figs. 11, 12); each gonocoxite basally with patch of long, dense, golden setae, merging on and crossing hypandrium dorsally, forming conspicuous golden belt (Figs. 7, 8, 11); median region of gonocoxite with round, tumid protuberance, with sparse short black setae (Figs. 7, 8, 12); apical region of gonocoxite serrated (Fig. 12); hypandrium black, subtriangular, with sparse long setae laterally; apex with 3 small lobes (Fig. 11); aedeagus with 2 long, acute terminal tubes (Fig. 13); ejaculatory apodeme long and very narrow (Fig. 13).
Size. Body length 15.5 mm. Wing length 10 mm.
Female. Similar to male, except: ovipositor (Figs. 14–17) shining black, strongly compressed laterally, mainly on ventral part; median sclerite at posterior end of furca (remnant of tIX) absent; spermathecae (Fig. 18) situated between segment VIII and IX; capsules are usually seen on base of segment VII; genital fork with long arms, slightly more than 2.5 times the length of expulsory ducts (Fig. 18); 2 expulsory ducts; capsular ducts 1/3 the width of expulsory ducts and slightly longer; 2 spherical capsules, 1/4 of length of capsular ducts in diameters (Fig. 18).
Geographical records. Brazil (Pará state and Piauí state).
Etymology. The specific name aureocingulatus refers to the basal region of the gonocoxite, with a patch of long, dense, golden setae, directed to the opposite side, crossing over the tip of the hypandrium, forming a conspicuous golden belt.
