Description. Both sexes. Head shape and chaetotaxy as in Fig. 3 View FIGURES 3–7 . 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 View FIGURES 3–7 . Thoracic and abdominal segments as in Figs 1–2 View FIGURES 1–2 .

Male. Thoracic and abdominal chaetotaxy as in Fig. 1 View FIGURES 1–2 ; aps absent on tergopleurite IV, but present on tergopleurites V–VII. Genitalia as in Figs 4–6 View FIGURES 3–7 : basal apodeme slender, rectangular, with rounded anterior end and slight constriction at mid-length ( Fig. 4 View FIGURES 3–7 ). 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 View FIGURES 3–7 ). Parameral heads irregular with broad parameral blades, tapering distally ( Figs 5–6 View FIGURES 3–7 ). Measurements: Ex Dicrurus remifer peracensis (n = 1): TL = 1.51; HL = 0.41; HW = 0.33; PRW = 0.22; PTW = 0.30; AW = 0.43.

Female. Thoracic and abdominal chaetotaxy as in Fig. 2 View FIGURES 1–2 ; psps present on tergopleurite VIII. Subgenital plate as in Fig. 7 View FIGURES 3–7 , 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 View FIGURES 3–7 ). 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.
