Type locality. -

PAPUA NEW GUINEA: Karimui.

Etymology. -

The species is named after the type locality: Karimui; noun in apposition.

Diagnosis. -

This new species differs from all congeners by smaller size, short male FWs without apical field, and shape of male and female genitalia. Male subgenital plate more elongate than in congeners, with a short apical expansion. Male genitalia very different from all congeners, characterized by elongate apical part of pseudepiphallus forming a long spoon-like finger.

Description. -

Small sized among congeners (Fig. 26 View Figure 26 ). Dorsum of head yellow brown with 6 narrow red brown irregular longitudinal bands (Fig. 4M View Figure 4 ). Fastigium unicolorous red brown (Fig. 4M View Figure 4 ). Scapes yellow brown. Antennae basally yellow brown, distally dark brown with some light rings. Fastigium verticis brown with a pale yellow-brown n-shaped pattern; frons brown in middle with 2 small yellow spots, black beneath scapes; clypeus and mouthparts dark brown dorsally, labrum and ventral part of mouthparts yellow (Fig. 5M View Figure 5 ). Pronotal disk yellow brown with some irregular red-brown patterns most prominent near anterior and posterior margins (Fig. 4M View Figure 4 ). Lateral lobe of pronotum red brown, distinctly darker than disk, with 2 light spots in antero-ventral corner (Fig. 6M View Figure 6 ). Legs yellow brown with dark brown spots. FIIIs brown, knees dark brown. Tergites brown, with posterior margin darker.

Male. FW very short, reaching apex of third abdominal tergite. FW coloration (Fig. 7L View Figure 7 ): Dorsal field cells and veins mostly brown; some veins near basal area cream-colored; with area between M and R infumate cream-colored; basal FW area with a large cream-colored spot including base of CuA, 1A and 2A. Lateral field brown, with ventral margin cream-colored. FW venation typical of genus; 1A notch anteriorly to angle strong; oblique vein bifurcated, posterior and anterior branches slightly bisinuate and almost parallel. Apex of dorsal field very short and rounded; D alignment limited to 2 cells; apical field absent. Subgenital plate very elongate, pointed, with a short apical expansion (Fig. 26C View Figure 26 ).

Male genitalia: (Figs 8L View Figure 8 , 24C View Figure 24 , 24D View Figure 24 ) Pseudepiphallus elongate, slightly convex dorsally, its basal margin slightly convex, prolonged anteriorly by a sclerotized plate; lateral margin tapering into apical third, most narrow at apical third; posterior of apical third elongated spoon shaped, its apex rounded. Rami very short, way shorter than half the pseudepiphallus length. Pseudepiphallic parameres small, posterior half broadly bulbous and stout. Ectophallic apodemes parallel and long, usually reaching anterior margin of pseudepiphallic sclerite. Endophallic sclerite elongate, with anterior region long but barely reaching anterior margin of pseudepiphallic sclerite; with lateral arms of sclerite narrowly triangular.

Female. FW reaching middle of second tergite; brown, without basal spot (Fig. 9J View Figure 9 ).

Female genitalia: Ovipositor slightly longer than FIII. Copulatory papilla conical, smaller and stout; apex folded ventrally, short, pointed; dorsal face with a sclerotized area; ventro-anterior end forming an oval to pyriform rim (Figs 10K View Figure 10 , 10L View Figure 10 ).
