MATERIAL. Holotype – ♂, Malaysia: Borneo I., Sabah State, Trus Madi Mt, ~ 1000 m, primary/secondary forest, at light, 13–25.V 2007, A. Gorochov ( ZIN).

DESCRIPTION. Male (holotype). General appearance very similar to that of E. (E.) carinata sp. n. including venation of proximal halves of both dorsal tegminal fields (Figs 84, 85). Coloration greenish with brown proximal half of left dorsal tegminal field (but medial part of this darkened area almost light brown), dark brown lateral two thirds of proximal half of right dorsal tegminal field, semitransparent membranes of mirror and some nearest cells in right tegmen, and light brown same marks on other bodyparts as in E. (E.) carinata sp. n. and E. (E.) semicarinata sp. n. Tegminal stridulatory apparatus as in Figs 83–85; abdominal apex almost as in E. (E.) carinata sp. n., but cerci practically intermediate between those of this species and E. (E.) semicarinata sp. n., and genital plate with curved upwards distal parts of posterior lobes clearly shorter as well as directed slightly forwards in rest position and more or less spine-like (i.e. with almost acute apices; Figs 70–74 ).

Female unknown.

Length (in mm). Body 22.5; body with wings 45; pronotum 5; tegmina 27; hind femora 19.5.

COMPARISON. The new species differs from the most similar species E. (E.) carinata sp. n. in the characters of the male genital plate listed above, and from all other species of Elbenia s. str., it is distinguished by the same features as E. (E.) carinata sp. n.

ETYMOLOGY. The new species name is the Latin word “apicata ” (with anything at the top: for example, with a cap on the head) due to the presence of an almost spine-like apical part on each lobe of the male genital plate.
