Binaluana emarginata sp. nov.

( Figs 1–60 )

Etymology. Melichar intended to name this species “ emarginata ”, as written on the label and refers to the characters of frons (without carinae). We kept the name he had chosen.

Diagnosis. Coloration and pattern on dorsal view on the tegmina draw a whitish hastate leaf shaped figure. Description. Total length 1.24 cm.

HEAD. Vertex with anterior margin rounded anteriorly. Vertex: proportion A/B = 0.33. Frons: proportion C/E = 0.15; proportion D/E = 0.39.

THORAX. Pronotum: proportion F/B = 0.53. Mesonotum: proportion G/F = 2.12, proportion G/B+F = 0.73, proportion G/H = 0.68. Tegmina: proportion I/J = 3.51.

MALE. Unknown.

FEMALE TERMINALIA. Seventh abdominal sternite almost rectangular when seen from bellow. The protuberance observed on the middle of the sternite is large and rounded with an important concavity visible above when viewed from behind.

Coloration ( Figs 1–11 ). Vertex brown, darker at the base almost black. Frons homogeneously brown with the exception of the upper protrusion darker. Clypeus as frons, with darker lines laterally. Rostrum with subapical segment light brown and apical segment yellowish. Lateral part of head between light cream to dark brown, specially along the frontal margins, where alternative patches can be observed, brown line going from the base of compound eyes to posterior margin, above the foramen of antenna. Pedicel of antenna light yellow with a single narrow brown line, visible on frontal side. Pronotum generally brown with yellowish patches, with the exception of median disc brown. Mesonotum brown, with yellow patches laterally and posteriorly. Scutellum brown. Pro- and mesothoracic legs reddish with yellowish apex on the femur, tibia with dark brown to black apex, all tarsal segment yellow. Metathoracic femur brownish and tibia yellowish, with a traversal brown line at the base of apical teeth. First tarsal segment yellowish with base and apex brown, second and third tarsal segment yellowish. Abdomen brown with reddish patches on the dorsal part and yellowish patches on the ventral side. Female terminalia dark brown to black.

Type material. Holotype, female, labeled ( Fig. 8 ): [N. Palawan / Binaluan / Nov.-Dez.1913 / leg. G. Roetcher], [Transcriptio / Nomen invalidum / Druh nebyl Melicha- / rem popsán] hand written label in Czech by Pavel Lauterer who wrote: invalid name, the species was not described by Melichar, [ Binaluana ng. emarginata nsp.], [Collectio, Dr. Melichar, Moravaké museum Brno] – deposited in MZM.

Distribution. The Philippines: Palawan Island.
