Etymology. Species named after the type locality.

Distribution. Indonesia, south and south-east of Sulawesi Island.

Diagnosis. Species close to several species of the Novaeguineae species group, especially to Cardiodactylus frustorferi n. sp., C. guttulus and C. kondoi , but differing by its lighter coloration and male and female genitalia; the species is also close to C. contrarius n. sp. which has a lighter coloration of FWs and a longer pseudepiphallus.

Description. Size average for the genus ( Figs 1 View FIGURE 1 , 46A–D View FIGURE 46 ). Head: Dorsum yellowish brown with four dark brown longitudinal bands, the median ones punctuated, and a brown triangle posterior to eye (5N). Fastigium black, its margins yellow. Antennae, scapes and face almost homogeneously yellow brown. Lateral side of head gray brown. Maxillary palpi yellow brown, apex slightly darker. Pronotum: Dorsal disk yellow brown mottled with dark brown; lateral margins whitish, posterior margin dark brown. Lateral lobes dark brown, ventral margin yellow. Legs orange brown with few darker spots; hind knees dark brown. Tarsomeres III-1 orange brown, darker at both ends, with 3 spines on dorso-external edges (n = 3). Hind wing tail gray brown, 1.5 times as long as the pronotum. Cerci yellow brown, with faint darker spots.

Male: FW coloration ( Figs 1 View FIGURE 1 , 9I View FIGURE 9 ): Dorsal field mostly whitish and brown. Whitish areas include bases of 3A–4A, transverse region of 1A, harp veins, bases of chords, wide transverse band posterior to mirror and apex of anal region. Black areas between bases of 1A and 3A, e1 cell and base of CuA. CuA/M area whitish and brown anteriorly. M and R orange brown anterior to their fusion, whitish posteriorly. Sc vein orange brown, its projections whitish; cells immediately ventral to Sc dark brown, more ventral part of lateral field whitish. FW venation ( Fig. 9I View FIGURE 9 ): 1A slightly bisinuated. CuP absent. Harp with 2 w-shaped harp veins and 1 faint vein in anterior region. Mirror area: mirror (d1) not rounded, subdivided by a transverse vein, posterior part small; d2 little distinctive, separated into several longitudinal cells, longer than wide; e1 cell not crossed by transverse vein. Apical field with 5 cell alignments. Lateral field with 9 projections of Sc (n = 1) and 4 more ventral longitudinal veins.

Male genitalia ( Fig. 46E–G View FIGURE 46 ): Pseudepiphallic dorsal ridges parallel, their anterior edges forming a right angle with the rest of the sclerite. Pseudepiphallic sclerite with latero-anterior expansions, membrane between them with short setae. Posterior region rounded, widened laterally, with a small rounded translucent area. Rami wide. Ectophallic arc complete, with a short posterior expansion. Bases of ectophallic apodemes with long anterior expansions and short posterior ones. Apex of ectophallic fold trilobate, laterally sclerotized; median lobe rounded, sclerotized basally. Endophallic sclerite wider than long, with a short anterior expansion; lateral arms fused with lateral sclerites of ectophalic fold. Endophallic apodeme with lateral lamellas and a narrow medio-dorsal crest. Membrane of endophallic cavity plicate.

Female: FW coloration ( Fig. 12D View FIGURE 12 ): mostly dark brown. External margin of dorsal field successively dark brown and whitish, starting from base of longitudinal veins whitish. Inner part of dorsal field dark brown, except a translucent area at one third of FW length. M/R area brown with whitish veins until FW mid-length, with a whitish sclerotization at mid-length, as in males, then dark brown until posterior margin. R/Sc area and veins orange brown, projections of Sc and more ventral veins whitish. Posterior angle white, including distal parts of R and Sc. FW venation ( Fig. 12D View FIGURE 12 ): dorsal field with 10 (n = 2) strong longitudinal veins; lateral field with 9–11 (n = 2) longitudinal veins including 5–6 projections of Sc and 4–5 more ventral veins. Ovipositor: Shorter than FIII; apex with both dorsal and ventral edges denticulate ( Fig. 13O View FIGURE 13 ).

Female genitalia ( Fig. 15E View FIGURE 15 ): Copulatory papilla triangular, with baso-lateral sclerites; apex rounded, sclerotized and folded ventrally.

Juvenile: Contrasted coloration ( Fig. 47A View FIGURE 47 ), mostly light brown and yellow brown mottled with dark brown spots. Head coloration as in adults; pronotum yellow brown with few dark brown spots.
