Kelso, Scott Zootaxa 2023 2025-03-05 5599 1 1 271 Foldvari, Skevington & Motamedinia Foldvari, Skevington & Motamedinia 2023 [151,913,151,178] Insecta Pipunculidae Tomosvaryella Animalia Diptera 196 197 Arthropoda species seticosta sp. nov.   Figs 89A–E, 139, 155B   Diagnosis:This species can be recognized by the upper side of the basal costal cell having two long, brown bristles and 3–4 short, light brown bristles; symmetrical surstyli, broadened basally, moderately narrowed to apex in dorsal view ( Fig. 89A); gonopods with two different different-sized finger-like projections towards surstyli ( Fig. 89B); hypandrial apodeme distinct; subepandrial sclerite with a long protrusion along its middle in ventral view ( Fig. 89B).   Description: MALE:Body length: 2.8–3.2 mm. Head. Flagellum short acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black; lower part distinctly silver pollinose; eyes touching for distance equal to 1.5 times the length of ocellar triangle. Occiput silvery pollinose, less so on upper 1/3, but it is silver all along the edge of the eyes. Thorax. Postpronotum pale, with 8–10 pale bristles. Mesonotum (viewed obliquely from front) brownish pollinose, anterior part more grey, grayish also from the side and the posterior edge (2 small patches). Scutellum silvery pollinose and with 6–8 weak bristles along the distal edge. Dorsocentral bristles distinct, dark, somewhat longer along frontal edge, numerous dark bristles around postpronotum present. Halter, knob pale with brownish tinge, stem brown. Legs. Mid coxa with 4–5 long brown bristles. Trochanters and femora dark brown, shining ventrally, silvery pollinose posteriorly except shiny hind femur; knees and basal 1/4 of tibiae yellow (tibiae otherwise brown), tarsal segments yellow-brown, ventrally paler, last segment darker. Hind trochanter with a half circle, no distinct bristles, half circle with flat part dorsally; two ventrobasal spines present on fore femur but absent on mid femur. Ventroapical row of spines on fore femur 5–7; 8–10 small, black spines on mid femur; hind femur without ventroapical spines, except 18–20 equally spaced bristles posteroventrally, longer on distal half, longest up to 1/2 the width of hind tibia at distal end, outer edge (lateral side) with 10–12 stronger dark spines in the middle line. Subapical (distal) spines on first four tibiae absent. Hind metatarsus moderately flattened and almost as long as 2–5 combined, with scrub-like bristles ventrally, strong spine-like bristles dorsally on all tarsi. Pulvilli shorter than last tarsal segment. Wing. Length: 3.5–3.6 mm. Upper side of basal costal cell with two long brown bristles and 3–4 short light brown bristles. Fourth costal section 2–2.5 times as long as third costal section. Cross-vein r-m at middle of discal cell. 4–5 distinct brown setulae on tegula. Abdomen. Viewed obliquely from front tergites subshining black, tergite 1 silvery grey, silvery pollinose lateral spots on tergite 5. Dispersed strong dark bristles on all tergites absent. Lateral spines on first tergite present, 5–7 short dark bristles up to 0.6 times as long as width of hind femur at base. Postabdomen in dorsal view: T6, S7 invisible; T5 3 times as long as ST8. Genitalia without dissection: ST8 small, rounded in dorsal view, brown and without distinct bristles, but with velvet-like coverage; membranous area round, mostly directed posteroventrally; epandrium brown, surstyli yellow and brown. Genitalia. Genital capsule in dorsal view: epandrium slightly longer than wide (MLE:MWE = 1.07). Surstyli rather symmetrical, broadened in basal two thirds, then narrowed to apex ( Fig. 89A). Genital capsule in ventral view: gonopods small with two finger-like projections towards surstyli, right is longer than left one, subepandrial sclerite with a protrusion along its middle; hypandrial apodeme prolapsed phallic guide strong ( Fig. 89B); Genital capsule in lateral view: both surstyli widened, curved towards sternite ( Fig. 89D–E). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 89C).  FEMALE:Body length: 3.1–3.2 mm. As male except for the following characters. Frons, eyes separated, as wide as 1.2–1.4 times the width at antennae; completely silver-grey pollinose, only shiny black directly in front of ocellar triangle, ca. 1/6 of the frons, very short transition zone; frons with a short ridge in front of the ocelli in the median line. Enlarged ommatidia silvery shining. Pulvilli and claws about 2–2.5 times as long as last tarsal segment, smaller on hind tarsomeres. Female abdomen with silver spots on sides of tergite 6. Ovipositor.Straight in ventral view, robust, curved towards sternite apically in lateral view (yellow piercer, brown base), reaching distal end of 3 rdsegment; base brownish pollinose with occasional bristles. LP:LB = 3.5. LDP:LPP = 2.5. ( Fig. 155B).   Etymology:The name refers to the bristles found on the basal costal cell and comes from the Latin seta, bristle.   FIGURE 89.
