Chaetotaxy: white to yellowish white setose, except punctations golden; katatergite and anatergite yellowish white setose; macrosetae: 2 notopleural and 1 supra-alar black, 2 postalar ( Fig. 26G View FIGURE 26 ), 2 marginal scutellar ( Fig. 26G View FIGURE 26 ) and 2 posterior anepisternal reddish to reddish brown.
Wings ( Fig. 26H View FIGURE 26 ): translucent; brown microtrichia on posterior and distal half; veins yellowish on basal third, light brown on mid third and dark brown on apical third; cell r 5 open; halteres pale yellow.
Legs ( Fig. 26B View FIGURE 26 ): mostly yellow, except hind femur reddish yellow on distal half; fore and mid tibiae slightly darkened distally, hind tibia reddish brown on distal half; fore tarsus light brown, mid and hind tarsi reddish brown; all tarsi darker towards apex with last tarsomeres black. Chaetotaxy: coxae and trochanters white and femora yellow setose fore femur with 1 anterodorsal, 1 anterior distal, 2 dorsal distal and 2 posterodorsal yellow macrosetae; mid femur with 2 anterior, 1 anterodorsal, 1 dorsal and 1 dorsal distal yellow macrosetae; hind femur with 1 anteroventral and 2 dorsal distal yellow macrosetae; tibiae with yellow macrosetae and setae, hind tibia reddish and black on distal half; tarsi with reddish brown and black macrosetae dorsally and reddish ventrally; brush setae reddish; claws black; empodium and pulvilli yellowish.
Abdomen ( Fig. 26A–B View FIGURE 26 ): black, punctate with yellowish setae; tergites laterally white setose; T1 with 4 and T2 with 2 yellowish and T6 with 2 white lateral marginal macrosetae; T3–5 without macrosetae; sternites light brown with a yellow band posteriorly, sparsely white pruinose.
Terminalia ( Fig. 27 View FIGURE 27 ): reddish brown, yellowish white setose; rectangular in dorsal and ventral views ( Fig. 27A–B View FIGURE 27 ); epandrium ellipsoid in dorsal view, posterior margin obtuse, dorsally setose ( Fig. 27A, E View FIGURE 27 ); cercus small, reniform, dorsally setose ( Fig. 27A, E View FIGURE 27 ); subepandrial sclerite resembling a dagger, enlarged at base and setose dorsally ( Fig. 27A, E View FIGURE 27 ); gonocoxite rounded basally resembling a kidney with posterior half rod-like and sparsely setose ( Fig. 27C, G–H View FIGURE 27 ); gonostylus digitiform, directed upwards apically ( Fig. 27C, G–H View FIGURE 27 ); hypandrium deltoid, resembling a bivalve shell ( Fig. 27F View FIGURE 27 ); phallus with long prongs ( Fig. 27I–K View FIGURE 27 ); parameral sheath rounded posteriorly ( Fig. 27I View FIGURE 27 ); parameral apodeme directed anteriorly and ventrally ( Fig. 27I–K View FIGURE 27 ); ejaculatory apodeme fan-shaped, weakly sclerotized ( Fig. 27J View FIGURE 27 ).
Length. Body: 12 mm; wings: 10.7 mm.
Holotype condition. Good, terminalia dissected.
Female ( Figs 26F View FIGURE 26 , 28 View FIGURE 28 ). Similar to male, except mystacal macrosetae dark brown to black; postpedicel with sensorial area smaller ( Fig. 26F View FIGURE 26 ) and terminalia reddish brown, yellowish white setose; T 9+ T 10+cercus constricted laterally shortly before apex, rounded posteriorly and indented medially, dorsally and laterally setose ( Fig. 28A View FIGURE 28 ); hypoproct conic ( Fig. 28B View FIGURE 28 ); S8 almost trapezoidal, slightly concave mid-anteriorly, mid-posterior margin slightly salient ( Fig. 28C View FIGURE 28 ); spermathecae with 3–4 turns; spermathecal ducts and sperm pump sclerotized ( Fig. 28D View FIGURE 28 ).
Variation. Fore and mid tarsi reddish brown.
Etymology. fritzi = a patronym to Dr Fritz Geller-Grimm, Asilid researcher at Museum Wiesbaden Naturhistorische Sammlungen (MWNH), Wiesbaden, Germany.
Distribution. Brazil (Bahia and Minas Gerais) ( Fig. 39 View FIGURE 39 ).
Phenology. The largest number of collection events for this species occurred in November and December with a disjunct occurrence in February (Tab. 1), which coincides with the late spring and summer season in the southern hemisphere.
Taxonomic discussion. Aphestia fritzi sp. nov. differs from other species by the presence of lateral marginal scutellar macrosetae only on T1, T2 and T6. Differs from the most similar species Aphestia amazonica sp. nov., by the shape of cercus, reniform ( Figs 27A, E View FIGURE 27 , 28A View FIGURE 28 ); subepandrial sclerite resembling a dagger ( Fig. 27A, E View FIGURE 27 ); and gonocoxite rod-like on distal half ( Fig. 27G–H View FIGURE 27 ). Can be differentiated from Aphestia annulipes ( Macquart, 1838) and Aphestia fisheri sp. nov., by the presence of only one pair of marginal scutellar macrosetae ( Fig. 26G View FIGURE 26 ).
