Elbenia (Elbenia)?tenera Brunner-Wattenwyl, 1878

Figs 123–132

MATERIAL. Malaysia, Borneo I., Sabah State: 1 ♂, southern part of Kinabalu National Park , 1500–2000 m, primary forest, at light, 26.IV–2. V 2013, A. Gorochov , M. Berezin , V . Gorochova, E. Tkatsheva ( ZIN); 23 ♂, 3 ♀, Trus Madi Mt , ~ 1000 m, primary/secondry forest, at light, 13–25. V 2007 , A. Gorochov ( ZIN).

NOTE. The specimens from Trus Madi Mt are in accordance to the original descriptions of E. (E.) tenera and E. triangularis Brunner-Wattenwyl, 1898 which are now considered as synonyms to each other ( OSF). Their type localities were mentioned as “Borneo” ( Brunner-Wattenwyl, 1878) and “ Kina Balu [Kinabalu Mt] in ins. Borneo“ ( Brunner-Wattenwyl, 1898), but my male from Kinabalu Mt is distinguished from the males from Trus Madi Mt as well as from the figure of E. triangularis given in the latter publication by a wider interspace between the male last tergite lobes (compare Figs 123, 126 with 132); however, the picture of this tergite given in the first description of E. (E.) borneensis from Sarawak State ( Karny, 1926a) is very similar to my male from Kinabalu Mt (see Figs 123, 126 and 133). Moreover, all my males from Trus Madi Mt have all the other characters practically indistinguishable from those of the latter male. Thus, such differences in the structure of this tergite may be individual variations, but I have only one male from Kinabalu Mt, and it is a reason that my determination of this species is problematic.
