Type locality. -

INDONESIA: West Papua: Mamberamo River, Albatros Bivouac.

Etymology. -

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

Diagnosis. -

This new species differs from all congeners by male genitalia with pseudepiphallus forming at the posterior end two long straight lophi with subacute apices and by female copulatory papilla with a very thin elongate apex.

Description. -

Average to large sized among congeners (Fig. 23 View Figure 23 ). Dorsum of head with broad red brown bands narrowly separated (Fig. 4K View Figure 4 ). Fastigium red brown (Fig. 4K View Figure 4 ). Scapes yellow brown with red brown bands. Fastigium verticis brown with faint yellow vertical stripes, frons light brown without spots in the middle, dark brown ventral of scapes; clypeus and mouthparts red brown (Fig. 5K View Figure 5 ). Pronotal disk red brown with some irregular yellow brown patterns, lighter lateral ovular spots near anterior half and with a yellow brown stripe near latero-posterior margin (Fig. 4K View Figure 4 ). Lateral lobe of pronotum unicolorous dark red brown, not distinctly darker than disk (Fig. 6K View Figure 6 ). FIs, FIIs, TIs, and TIIs dark brown with yellow brown spots and rings. FIIIs brown, knees and posterior third of FIIIs dark brown. Tergites brown with posterior margin darker.

Male. FWs reaching middle of fourth abdominal tergite. FW coloration (Fig. 7K View Figure 7 ): Dorsal field cells and veins mostly brown with area between M and R infumate cream-colored; basal area with a small cream-colored spot on external corner. Lateral field hyalinous brown. FW venation typical of genus; 1A notch anteriorly to angle strong, making anterior part of harp wider; harp elongate, almost twice as long as wide. Oblique vein bifurcated, posterior branch slightly bisinuate, anterior branch bifurcated near 1A angle. Apical field with one cell alignment posterior to mirror. Apex of dorsal field rounded.

Male genitalia: (Figs 8K View Figure 8 , 24A View Figure 24 , 24B View Figure 24 ) Pseudepiphallus triangular, stouter, not convex dorsally in lateral view, its basal margin slightly indented in the middle, lateral margin generally parallel, not widened basally at base of rami, gently tapering into apex; apex forming two long straight lophi with subacute apices. Rami very short, about half the pseudepiphallus length. Pseudepiphallic parameres stout. Endophallic sclerite with a main Y shape; anterior region short and not reaching anterior margin of pseudepiphallic sclerite; posterior apex trilobate, with stick-like lateral arms and with a large median posterior expansion.

Female. FWs slightly surpassing second tergite. Dorsal field with a distinct cream-colored rounded spot at base and a tiny apical spot (Fig. 9H View Figure 9 ).

Female genitalia: Ovipositor distinctly longer than FIII. Copulatory papilla cupular basally, circled by a narrow sclerite expanded in apical region as parallel sclerotization; apex elongate and folded ventrally, terminated by a rounded area (Figs 10H View Figure 10 , 10I View Figure 10 ).
