Rhinotora paschoali Calhau & Coelho View in CoL sp. nov.
( Figs 3A–G View FIGURE 3. A – G , 10 View FIGURE 10 )
Diagnosis. Rhinotora paschoali sp. nov. is the only species in the genus that lacks strong ventral seta on mid and hind femora, besides having the most developed anterior orbital seta in the genus. It shares with R. spiloptera the fore femur proportions (about four times longer than wide). On the other hand, this species is similar to some specimens of R. lopesi concerning the branched supernumerary crossvein arising from the middle of R2+3. Likewise R. lopesi , R. spiloptera and R. travassosi , the scutum has a complex pattern of brown and golden pruinose stripes and spots. The male genitalia in this new species is very distinctive, with cerci laterally expanded in fingerlike projections and phallus flattened, laterally L-shaped.
Description. Male. Body length, excluding antenna and abdomen: 3.40 mm. Head ( Figs 3A–C View FIGURE 3. A – G ). Height: 0.83 mm, width: 1.53 mm. Yellow to brown, silvery to golden pruinose. Compound eye yellowish. Frons and vertex medially brown, yellow around compound eye, with a pair of lateral dark spots on anterior margin of frons. Frons golden pruinose. Anterior reclinate orbital seta about as long as one third of posterior seta. Ocellar triangle brown. Face yellow with a dark brown band below antennae. Gena yellow with an oblique medial brown stripe. Subgena yellow to brown. Postgena yellow. Median occipital sclerite brown, shiny. Occiput yellow, black setulose. Mouthparts yellowish. Antennae ventrally yellow, dorsally brown. Arista preapical, micropubescent. Thorax ( Figs 3A–B View FIGURE 3. A – G ). Yellow to brown. Scutum brown with yellowish areas; black setulose, with complex pattern of brown and golden pruinose stripes and spots; posteromedial paired spots converging posteriorly. Pleura mostly dark brown with paler areas and a wide pruinose band from anepisternum to postpronotal lobe. Scutellum triangular with apical and lateral spiniform protuberances; base of apical seta protuberant. Scutellum yellowish brown, golden pruinose, shiny at apex and on lateral spines. Wing ( Fig. 3D View FIGURE 3. A – G ). Length: 4.80 mm, width: 1.44 mm, Medial vein ratio: 0.51. Veins mostly dark brown with white and yellow areas; C mostly yellow, dark brown on distal two thirds of cell c. Membrane hyaline with dark spots. Cell r1 with seven to eight simple supernumerary crossveins. Cell r2+3 with a branched supernumerary crossvein arising from the middle of R2+3. Legs ( Fig. 3A View FIGURE 3. A – G ). Mid and hind coxae yellow to brown, black setulose. Fore femur brown on proximal two thirds, yellow on distal third, black setulose, with longer setulae on posterodorsal surface. Fore femur about four times longer than wide. Mid femur brown on proximal two thirds and yellow on distal third. Mid femur with black setulae, ventrally longer. Mid femur without strong ventral setae. Hind femur brown with a subapical yellow spot. Hind femur without strong ventral setae. Fore tibia yellow on first and third quarters, brown on second and fourth quarters. Mid tibia brown, yellow at base and third quarter. Mid tibia with one distinct apical ventral seta. Hind tibia brown, yellow at base and on medial third. Abdomen. Tergites dark brown, sternites yellowish brown; tergites short brown setulose, setulae longer laterally on posterior margin. Protandrium ( Fig. 3E View FIGURE 3. A – G ). Sternite 5 medially membranous. Sternite 6 fused with sternite 5. Male genitalia ( Figs 3F–G View FIGURE 3. A – G ). Cerci fused to each other and to epandrium; laterally expanded in a pair of fingerlike projections. Surstylus rectangular in lateral view, inner surface microtrichose. Phallus flattened, laterally L-shaped, apex thin.
Etymology. The specific epithet is a patronym honoring Paschoal Grossi, Brazilian coleopterist and eminent insect collector.
