Spiloscapha bryanti sp. n.

( Fig. 8 )

Type material. Holotype: JAVA , ♀, Kawah Manoek , 10.IV.1909, leg. G. E. Bryant, BMNH .

Description. Shape and colour pattern of pronotum and elytra see Fig. 8 . Head, pronotum, and scutellum brown; elytron brown with a black spot in the posterior part not reaching tip, lateral margin, suture and ventral side of body brown. Head with similar punctation as on pronotum; antenna bicoloured with antennomeres 1–4 brown and antennomeres 5–11 dark brown. Pronotum with fine punctures, distance between punctures 2–8 times longer than puncture diameter, surface between punctures distinctly shagreened; anterior margin medially unbordered, basal margin unbordered. Elytron with 8 somewhat irregular rows of punctures without striae, third row with approximately 38 punctures; intervals flat, with a few scattered punctures, surface between punctures shining; lateral margin visible from dorsal nearly on its entire length. Punctures on metaventrite and abdominal ventrites distinctly coarser laterally than medially. Aedeagus unknown, only female available. Body length 3.0 mm.

Diagnosis. Spiloscapha bryanti sp. n. can be recognized by its body shape and dorsal colour pattern. The colour pattern of S. bryanti sp. n. is similar to that of S. palawanica Schawaller, 2004 from the Philippines (Palawan), but the latter species is distinctly flatter, more elongate and parallel sided, the surface between the pronotal punctures is shining, the elytral intervals are posteriorly slightly convex, and the dark elytral spot reaches the lateral margin and suture. The other known species from Java, S. javanicum Gebien, 1925 has a completely different dorsal colour pattern (figured in Schawaller 1997), and also a longer body shape.

Etymology. Named in honor of Gilbert Ernest Bryant (1878–1965), former entomologist in BMNH, specialist of Chrysomelidae and collector of the holotype.
