Andrewes, 1919: 299 ( Sarawak , Borneo); 1933: 348; Deuve, 2001: 565 , 571. MATERIAL. 2♂♂ , ♀ (SIEE) labelled: Bali Island , near Tamblingan Lake , 8º15´S / 115º06´E , h= 1200 m , 22–24.XI.2018 , leg. D. Fominykh. DISTRIBUTION. Borneo, Sumatra and Java; first recorded in Bali. The other two subspecies, E. m. darlingtoni Deuve, 2001 and E. m. negrosensis Deuve, 2001 are confined to the Philippine islands Luzon or Negros, respectively. HABITATS AND HABITS. No data. COMMENTS. Eustra matanga is currently recognized as a widespread oligotypic species that includes three subspecies, each defined by a distinctive right paramere, with E. m. darlingtoni being additionally different in a paler body. The specimens listed belong to the nominotypical subspecies and they are very similar and very close to E. posteroguttata sp.n. Additional small differences are as follows: BL 3.25–3.4 mm , body shiny pale brown, elytra each with an ill-defined to vague darker spot spanning 2/5 to 3/4 elytra; these spots widely separated from both each other and narrowly separated from reflexed lateral margins. Dorsal microsculpture distinct on on labrum, hardly taraceable on clypeus, otherwise missing; elytral aciculate microsculpture outside and partly including glabrous submarginal area. PW / PL 1.55– 1.62 (1.59, n=3), PW / HW 1.12–1.15 (1.13), PLw / PL 0.28, sides sinuate in front of obtuse and sharp basal angles, subsinuate behind apical angles. Base barely narrower than apex, PB / PA 0.89–0.93 (0.91). Lateral edge a bit more distinctly crenate, with 7–10 minute. Elytra slightly longer, EL / EW 1.37–1.44 (1.42), EW / PW 1.63–1.74 (1.70). Mesotarsomeres 1 and 5 shorter (TF2 1.10: 1.40, n=2); TF3 1.73– 1.82: 1.36. Aedeagus ( Figs 7–9 , 32 , 35–36 ) similar to those of E. csikii and E. posteroguttata sp.n. : apex of median lobe toothed, right paramere subclavate, as long as left one, with apex obliquely truncate ( vs . rounded in the two similar species). Internal sac with distinctive armature consisting of a cluster of a few apical sclerites. Acknowledgements . I am very indebted to A. Taghavi- an (MNHM) and Dr. K.V. Makarov (MPSU) for the loan of material under their care and to D. Fominykh ( Moscow ) for donating specimens. I extend my cordial thanks to Dr. Th. Deuve for his kind answers to my questions about the holotype of E. nageli .
