Neodiogmites papaveroi sp. nov.

( Figs. 43–51 )

Diagnosis. face yellow pruinose; frons black, yellow pruinose laterally; palpus black, white setose on first segment, black setose on second; pronotum black, brown pruinose; scutum black, yellow pruinose laterally and along dorsocentral stripe; coxae brown pruinose, white setose, femora black, tibiae largely reddish, apical third black, tarsomeres black; wing slightly darkened, alula hyaline, halter brown; abdomen black; tergites 2–4 with abundant, long, thin yellow setae laterally.

Redescription. Holotype male. Measurements: body 21 mm; wing 15.5 mm. Head: face yellow pruinose; mystacal setae black; frons black, yellow pruinose laterally, a tuft of black setae above insertion of each antenna; orbital setae black; ocellar tubercle black with black setae; postocular setae black; occiput yellow pruinose; upper occipital setae black and lower occipital setae white; palpus black, first segment white setose, second segment black setose; proboscis black with white setae ventrally; antenna black, scape and pedicel black setose, postpedicel yellow pruinose, short black setae on basal half dorsally. Thorax: second cervical sclerite brown pruinose, with thin black setae; pronotum black, brown pruinose, antepronotum with thick and thin black setae on anterior margin, postpronotum with thick and thin black setae laterally; proepisternum with thin black setae; postpronotal lobe black setose; three notopleural, four supra-alar and four postalar setae; scutum black, yellow pruinose laterally; paramedial stripe yellow, medial stripe black, paler than ground color of scutum dorsocentral setae just before transverse suture; scutellum with one pair of long and black marginal setae, thin black setae between them; pleura golden yellow pruinose; anepisternum anteriorly bare, without pruinescence, black setae posteriorly. Legs: coxae with light brown pruinescence and with white setae; fore coxae with mixed black and white setae; femora black; tibiae largely reddish, apical third black; tarsomeres black; femora with thin and long black setae, less abundant on hind femur; fore and mid tibiae black setose, yellow setae dorsally, hind tibia black, yellow pruinose with short yellow setae dorsally; tarsomeres black setose; pulvillus yellowish; claws black. Wing: slightly brownish; alula hyaline; brown halter. Abdomen: black, tergite 1 with thin and thick yellow setae laterally; tergites 2–4 with abundant, long and thin yellow setae laterally, tergites 5–8 with sparse thin yellow setae on posterior and lateral margins, remainder covered with short and black setae; sternites black with long and thin yellow setae. Terminalia black setose, cerci sparse yellow setose; epandrium narrow posteriorly ( Fig. 46 ); anterior margin of hypandrium medially with small indentation, posterior margin narrowed, slightly rounded ( Fig. 47 ), internal expansion of gonocoxite (internal view of gonocoxite) spatulate ( Fig. 49 ); dorsal expansion of gonocoxite with apex depressed ( Figs 48, 49 ); gonostylus tubular, apex erect ( Figs 48, 49 ), expanded basally, followed by another ( Fig. 49 ); phallus with lateral ejaculatory process smaller than ejaculatory apodeme in dorsal view ( Fig. 50 ), ejaculatory apodeme narrowed on basal 1/3 ( Fig.51 ) and aedeagal sheath without medial area acute in dorsal view.

Female: differs from male by: palpus black with yellow setae on first segment and black setae on second; proboscis black with yellow setae ventrally; lower occipital setae yellow; setae of first cervical sclerite yellow; proepisternal setae yellow; coxae with yellow setae; base of femora black and remainder red; tibiae red with black apex; abdomen with fewer setae than in males; tergites 5–8 shiny black. Terminalia: acanthophorite with black spines ( Figs. 43, 44 ), cerci apex truncate ( Figs. 43, 44 ), sternite VIII with mediolateral and central membranous areas, mediolateral area with larger base, posterior margin with medial invagination meeting membranous central area, forming two valves with truncated apex and convex lateral outer margin, lateral invagination followed by membranous mediolateral area ( Fig. 43 ). Spermathecae as in Fig.45 .

Variations: size: body 16–27 mm; wing 12–19 mm. Some paratypes varied in seed coat color and setation; palpus may have only black setae; coxae black setose or white and black setae mixed, extent of red color of femur and tibia variable; scutellum without thin black setae between marginal setae; abdominal tergite 1 black setose laterally.

Etymology. The name given to this species is in honor of the great Brazilian entomologist Dr. Nelson Papavero, who contributed significantly to the knowledge of Asilidae .

Comments. The specimens examined in this study had been identified as Dasypogon hirtuosus Wiedemann, 1821 by Messias Carrera (1949). However, the type of D. hirtuosus is not congeneric with this material.
