Description. Both sexes. Head shape and chaetotaxy as in Fig. 3. Lateral margins of preantennal area slightly convex; frons flattened; temples rounded; marginal carina broad, irregular, narrowing anteriorly; dorsal preantennal suture reaches dsms, ads and lateral margins of head; ventral anterior plate small, semi-circular; coni small; gular plate as in Fig. 3. Thoracic and abdominal segments as in Figs 1–2.
Male. Thoracic and abdominal chaetotaxy as in Fig. 1; aps absent on tergopleurite IV, but present on tergopleurites V–VII. Genitalia as in Figs 4–6: basal apodeme slender, rectangular, with rounded anterior end and slight constriction at mid-length (Fig. 4). Ventral sclerite narrow, widening distally, and reaching beyond anterior margin of mesosome; proximal mesosome broadly quadratic, short; mesosomal lobes broad, rounded triangular; rugose area not forming distinct bulging nodi; 2 ames sensilla on each side near antero-lateral corners of mesosomal lobes; 2 pmes sensilla on each side of gonopore near rugose area; gonopore small, with broad marginal thickening (Fig. 5). Parameral heads irregular with broad parameral blades, tapering distally (Figs 5–6).

Female. Thoracic and abdominal chaetotaxy as in Fig. 2; psps present on tergopleurite VIII. Subgenital plate as in Fig. 7, with slight lateral submarginal bulges; vulval margin gently rounded, with 2–3 long slender vms on each side, and 5–6 short, thorn-like vss on each side; 4–6 long, slender vos on each side; distal 2 vos anterior to vms (Fig. 7). Measurements: Ex Dicrurus remifer peracensis (n = 1): TL = 1.98; HL = 0.46; HW = 0.40; PRW = 0.25; PTW = 0.36; AW = 0.54.
