Other specimens studied: Papua New Guinea: Neu Guinea, Kaiserin Augustafluss Expedition 218, Lordberg, 29 November–2 December 1912 (coll. Bürgers)— 1 female (Berlin, ZMHB); KAE 210, Etappenberg, elev. 850 m, 19 November 1912 (coll. Bürgers)— 1 female (Berlin, ZMHB).

Diagnosis. The species can be recognised by the shape of the female subgenital plate that carry a pair of flattened and dorso-ventrally widened apical lobes that reach to about the end of the basal lobe of the ventral ovipositor valves, while the central plate terminates into a short lobe in about mid-length.

Description. Medium sized species. Tegmina surpassing middle of hind tibia. Femora with the following number of spines on ventral margins: fore femur 5–7 external, 5–6 internal; mid femur 6–8 external, 2–3 internal near base; hind femur 9–10 external, 9–16 internal.

Male. Unknown.

Female. Subgenital plate near base with a transverse furrow outlining a rim along the proximal margin; entire basal area rather short, obtuse angularly projecting behind in middle; lateral lobes compressed, curved, with rounded apex, embracing a circa heart-shaped space; this structure is used to hold the spermatophore after pairing with a male (Fig. 14); basal-lateral area greatly expanded dorsad, with a fold around mid-length and with two grooves separated by a curved carina running from basal to apical margin. Eight abdominal tergite with lateral-posterior area greatly excised. Dorsal margin of ventral ovipositor valves near base with an about semi-oval lobe that has the margin provided with long hairs.

Coloration. Yellowish brown with patterns 0, 1–4. Vertex and pronotum with a medium brown medial band with pattern 3 in midline. One female has dark dots on tegmina. Legs with dark brown spots on dorsal margins.

Measurements (female).—body: 19–25; pronotum: 5.5–5.8; tegmen: 32–34; hind femur: 15.5–16.5; antenna: 65–70; ovipositor: 10–11 mm.

Etymology. Named for the scattered dark spots on the fore wings, especially distinct in the female holotype.
