(Figs. 1 A, 2, 3A, 4A, 5A–C)
Type material. Holotype male: Indonesia: Province Maluku: Ambon [Is.], Gunung Seliman, 3-IX-1995 (R. de Jong) (RMNH).
Type locality. Indonesia, Ambon Island.
Etymology. Species named after the type locality of Ambon Island, Indonesia.
Distribution. Indonesia, Ambon Island.
Diagnosis. Species of small size, characterised by dark colouration, male FWs black with yellow intermedian area, no complete harp vein, harp without a distinctive rounded area; male genitalia with a narrow medio-dorsal crest on pseudepiphallic sclerite.
Description. Size small. Colouration contrasted mostly dark brown and orange brown. Head dorsum with 6 brown longitudinal bands (Fig. 2). Eyes well protruding. Fastigium wider than long, setose, darker than vertex and slightly carenated posteriorly to yellow median ocellus. Scapes yellow with dark brown patterns, antennae yellowish brown. Cheeks black, except a yellow area posterior to eyes and 3 yellow spots on ventral margin of eyes (Fig. 3 A). Face dark brown, with a median T-shaped yellow line, 2 yellow spots between scapes and 2 above epistomal suture; dorsal part of front head with two black spots. Labrum yellowish, its base dark brown; clypeus yellowish; mandibles yellowish with dark brown bases. Palpi yellow. Pronotum: Dorsal disk slightly trapezoidal, straight posteriorly; orange brown mottled with yellow and dark brown; lateral margins yellow; posterior margin dark brown. Lateral lobes black except two yellow spots on ventral margin (Fig. 3 A). Legs: median coxae yellow, with dark brown spots; fore and median legs orange brown and yellow. Hind femora almost homogeneous orange brown, knees dark brown, 5–6 dark spots on each ventral edge; hind tibiae black, their inner surface with 4 yellow spots above and between spurs; distal part of tarsomeres III-1 and III-3 and dark brown. Hind tibiae with 5 inner and 10 outer spines above spurs and 4 inner and 7 outer spines between spurs. Tarsomeres III-1 with 5 spines on dorsal outer edges and 1-2 spines at inner bases. Abdomen homogeneously dark brown dorsally; sternites yellowish brown. Cerci orange brown.
Male: FW almost not setose, not reaching abdomen midlength. FW colouration (Fig. 2): Cells homogeneously black, not translucent; dorsal field veins brown; Median and R veins black, intermedian area yellow. FW venation (Fig. 1 A): 1A angle right (90°). CuP faint, limited to FW basis. Harp wide, almost flat, with no complete harp vein, without a distinctive rounded area. CuA very faint, its distal part curved inwards, around the median fold. Diagonal vein prolonged posteriorly by a strong transverse vein fused to R. Longitudinal veins strong at apex, transverse veins faint. Mirror (d1) well differentiated but not rounded. Apical field restricted to a few cells in E alignment. Lateral field black, with 5 strong longitudinal veins including MA, R and 3 more ventral veins; latero-dorsal angle made by MP; R without bifurcating veins; distal part of MA and MP very weak. Subgenital plate short, not indented (Fig. 4 A).
Male genitalia (Fig. 5 A–C): Pseudepiphallic sclerite triangular; anterior apex bisinuate, its lateral part folded dorsally; posterior apex with individualized lophi, setose; pseudepiphallus dorsally convex with a narrow medio-dorsal crest starting between bases of lophi (Fig. 5 A). Apex of rami little sclerotized. Pseudepiphallic parameres with 3 elongate lobes. Ectophallic arc complete and wide, near base of pseudepiphallic parameres, prolonged ventrally by hook-like expansions. Ectophallic fold short and wide, with paired lateral sclerotizations. Endophallic sclerite long, reaching beyond pseudepiphallus anterior margin, with short lateral arms and a short medio-posterior expansion; endophallic apodeme without a median crest.
Female: unknown.
