Holotype.  “Za 21 | Mt. Matanga, W. Sarawak, G. E. Bryant. 16.II.14. | G. Bryant Coll. B.M.1926-86. | HOLOTYPUS Anomala matangensis sp. n. det. Zorn, 2007” (BMNH).
Description:
Body shape. Length: 7.8 mm, width: 4.3 mm; elongate oval, dilated behind; strongly convex. Color. Head reddish brown; pronotum reddish brown on the disc, yellowish brown towards the lateral margins; scutellum yellowish; elytra dark brown, with the apical part broadly pale yellow; sutural margin reddish; underside including femora and antennae pale yellowish; propygidium, pygidium, abdominal sternites, tibiae and tarsi reddish brown. Head. Clypeus trapezoid, anterior angles rounded; anterior margin reflexed; punctures moderately fine; frons transversely punctured, somewhat rugose; punctures more fine and sparse towards vertex. Pronotum. Width 1.56 times length; in dorsal view broadest at its base; lateral margins straight and subparallel posteriorly, curved and convergent in the anterior third; anterior angles acute; posterior angles rounded; basal stria complete; whole surface with fine and rather sparse punctation. Elytra. With impressed, coarse and somewhat umbilicate punctures, arranged in regular striae; sparse micropunctation intermixed; primary costae not elevated; subsutural, second and third interstice with one secondary row of punctures, the one of the subsutural interstice irregularly duplicated behind the scutellum; the three inner primary striae weakly sulcate at the apex; humeral and apical protuberance distinct, but not very prominent. Pygidium. Moderately fine punctured; punctures somewhat oblong near the distal margin. Metasternum. Disc sulcate, with minute sparse punctures; towards the lateral margin with very dense, umbilicate punctures and short yellowish setae. Abdominal sternites. Densely, sometimes confluently punctured; with a transverse series of short yellowish setae. Protibia. With a long, acute lateral tooth and a long pointed terminal tooth which is strongly curved outwards; terminal articulated spine short, about 2 times as long as wide. Metatibia. 2.5 times as long as wide, slightly fusiform. Claws. External middle claw and internal front claw cleft; the upper branch of the latter very small and spine-shaped; the lower branch much broader and longer, with an obtuse angle at its inner margin and distinctly excised before the strongly pointed apex. Aedeagus. See figs 6, 7.
Diagnosis:
Anomala matangensismatangensis is very similar to A. fulvofusca but can be distinguished by the different aedeagus (Figs 5, 6) and the coloration as described above.The degree of variation of the coloration pattern, however, is uncertain as long as no further material is available.
Etymology: The species epithet is referring to the type locality, Mt. Matang in western Sarawak, Borneo.
