Pipunculus pseudophanes Perkins, 1905 View in CoL

Diagnosis: This species can be recognized by the mid and hind femora bearing 8–15 short but distinct bristles posteriorly; surstyli triangle-shaped; narrowed in apical one third ( Fig. 82A View FIGURE 82 ); subepandrial sclerite short; gonopods wide, rounded at apex; ejaculatory ducts sinuous without any teeth in ventral view ( Fig. 82B View FIGURE 82 ); surstyli curved towards sternite in lateral view with same width from base to apex; phallic guide short, broadened at base with a hook-like projection in lateral view ( Fig. 82D–E View FIGURE 82 ); phallus with three ejaculatory ducts.

Redescription: MALE. Body length: 3.0 – 3.5 mm. Head. Flagellum acuminate; yellow-brown. Face silvery pollinose. Frons, upper part shining black, lower part distinctly golden pollinose; eyes touching for distance equal to 2 – 2.5 x length of ocellar triangle. Occiput silvery pollinose, slightly less so on upper half. Thorax. Postpronotum pale brown, with 2 – 3 whitish bristles. Mesonotum (viewed obliquely from front) subshining black, anterior part indistinctly brown pollinose; slightly brownish also from the side. Scutellum with dorsocentral bristles weakly developed, dark, somewhat longer on frontal part. Halter, knob pale, stem dark brown. Legs. Mid coxa with 2 – 3 dark bristles. Trochanters and base of femora brown, femora dark brown, shining ventrally, femora silvery pollinose posteriorly except shiny hind femur; knees, basal 1/3 of tibiae yellow, tarsal segments pale brown, last segment dorsally darker. Ventroapical row of spines on fore femur tiny, 4–6, 8–10 short, black spines on mid femur; 6–8 spines on hind femur, mid and hind femora with 8–15 short but distinct bristles posteriorly. Subapical (distal) spines on first four tibiae absent. Hind trochanter without bristles on smoothly curved ventral side, ventrobasal spines absent on fore and mid femora. Hind tarsi slightly flattened, first tarsomere slightly shorter than 2–5 combined; ventral bristles scrub-like. Pulvilli as long as last tarsal segment. Wing. Length: 2.8–3.1 mm. Upper margin of basal costal cell with one short bristle. Fourth costal section 2–3 times as long as third costal section. Cross-vein r-m distinctly distal to middle of discal cell. Setulae on tegula absent. Abdomen. Viewed obliquely from front tergites golden-brownish pollinose, tergite 1 silvery grey pollinose with 6–8 short lateral bristles (up to 0.15 mm), sides faintly silvery on tergites 4 and 5 (the latter with larger spot, but weakly colored). Dispersed short dark bristles on tergites absent. Postabdomen in dorsal view: T6, S7 invisible; T5 twice as long as ST8. Genitalia without dissection: ST8 small, mainly shiny brown; membranous area lanceolate, shaped like a sunflower seed, vertical; surstyli relatively small, brown; hairy cerci visible without dissection in lateral view. Genitalia. Surstyli hairy, wide at base in ventral view, narrowing at 2/3 of the length and broadening at tip, both uniformly wide in lateral view and pointed at tip; epandrium short and wide; cerci symmetrically placed, small; ST8 with a narrowing membranous area towards epandrium. Genital capsule in dorsal view: epandrium and surstyli dark brown. Epandrium wider than long (MLE:MWE = 0.6). Both surstyli broadened at base, triangle-shaped, narrowed in apical one third ( Fig. 82A View FIGURE 82 ). Genital capsule in ventral view: subepandrial sclerite short and narrow; gonopods symmetrical broad and rounded at apex; phallus trifid, ejaculatory ducts sinuous, without any teeth ( Fig. 82B View FIGURE 82 ). Genital capsule in lateral view: both surstyli gently curved to sternite, not narrowed at apex ( Figs 82D–E View FIGURE 82 ); phallic guide broadened with final thin hook-like projection, visible; ejaculatory apodeme flat; sperm pump elongated, linear ( Fig. 82C View FIGURE 82 ).

FEMALE. Body length: 3.0– 3.3 mm. As male except for the following characters. Frons, eyes separated, as wide as 1.2–1.5 times the width at antennae; completely silver-grey pollinose until up to ¾ of the frons, shiny black in front of ocellar triangle. Enlarged ommatidia silvery shining. Pulvilli and claws about 1–1.2 times as long as last tarsal segment. Female abdomen with silver spots on sides of tergites 3–6. Ovipositor ( Fig. 156D View FIGURE 156 ). Base dark brown with pale apical margin, piercer straight in ventral view, slightly up curved in lateral view.

Examined material: LECTOTYPE [ HERE DESIGNATED]: AUSTRALIA: Queensland: Cairns , [16°55’S, 145°46’E], 21.VIII.1904, JSS8479 (1♂, BPBM) GoogleMaps ; PARALECTOTYPE: AUSTRALIA: same location as lectotype, VII.1904, BMNH (E) GoogleMaps 964035, JSS 8480 (1♀, BMNH; 1♀, BPBM) .

Distribution: Australia (Queensland) ( Fig. 135 View FIGURE 135 ).

Notes: Based on the shape of the surstyli, this species is related to Tomosvaryella infundibula sp. nov. It differs by the shape of the ejaculatory ducts and surstyli in lateral view, with three long and sinuous ejaculatory ducts, without any teeth ( Fig. 48D–E View FIGURE 48 ); dorsomedial margin of surstyli bent towards sternites ( Fig. 48D–E View FIGURE 48 ); hind femur with bristles posteriorly. Perkins reared this species from a deltocephaline leafhopper, Hecalus sp. ( Perkins 1905). Specimen JSS8479 is hereby nominated as the lectotype to fix and ensure consistent interpretation of the name. Intraspecific genetic distance ranges from 0.0% to 0.3%. Tomosvaryella pseudophanes is genetically most similar to T. latistyla sp. nov. (5.6–8.8% pairwise divergence) (Supplementary file 3).
