Type host. Oriolus oriolus (Linnaeus, 1758) — Eurasian golden oriole. Type locality. None given, probably Germany.

Description. Both sexes . Head shape, structure, and chaetotaxy as in genus description and Fig. 198. Ventral anterior plate somewhat elongate. Preantennal nodi slender. Gular plate broad, short, with prominent median point. Head largely translucent, except preantennal, pre- and postocular nodi, gular plate, and parts of mandibles with dark pigmentation. Thoracic and abdominal segments as in genus description and Figs 196–197. Body almost entirely translucent, except proepimera, metepisterna; lateral tergopleurites III–VIII with dark pigmentation. Tergopleurite II in some specimens with slight dark pigmentation laterally.

Male. Abdominal chaetotaxy as in Table 2 and Fig. 196. Male genitalia typical for genus (Fig. 199). Basal apodeme rounded rectangular. Proximal mesosome gently rounded, short. Gonopore (Fig. 200) as subparallel convergent submedian thickenings, widely open proximally and moderately open distally. Mesosomal lobes wide, short, rounded; 2 pmes sensilla visible on each lobe proximally and 1 pmes visible distally; distal pmes may be microseta. Parameral heads (Fig. 201) folded into distinct U-shape, overlapping with basal apodeme. Parameral blades wide, blunt; pst1–2 as in genus description. Measurements ex Oriolus oriolus (n = 7): TL = 1.30–1.42; HL = 0.37–0.40; HW = 0.34–0.37; PRW = 0.21–0.24; PTW = 0.31–0.34; AW = 0.43–0.48.

Female. Abdominal chaetotaxy as in Table 2 and Fig. 197. Subgenital plate vaguely pigmented, gently rounded distally (Fig. 202). Vulval margin (Fig. 202) gently rounded, with 5–6 short, slender vms on each side, and 7–8 (one specimen with 12–14) short, thorn-like vss on each side; 7–8 long, slender vos on each side; distal 3–4 vos form transverse row just proximal of vss. Measurements ex Oriolus oriolus (n = 15): TL = 1.54–1.69 (1.60); HL = 0.38–0.43 (0.41); HW = 0.37–0.42 (0.39); PRW = 0.22–0.27 (0.24); PTW = 0.35–0.40 (0.37); AW = 0.49–0.59 (0.53).
