Material. Holotype — ♂: Malaysia, Pahang State, Tioman Island near Malay Peninsula (not far from Mersing in Johor State), environs of Juara vill. on eastern coast, 6– 14.04.2010, A. Gorochov , M. Berezin, E. Tkatsheva ( ZIN). Description. Male (holotype). Size, colouration and structure of body very similar to those of M. t. tabulophila ( Gorochov, 2011), comb. nov. but with following characters: head with light brown dorsum having almost whitish ocelli and distinct stripes and spots between greyish brown eyes (vs. this dorsum almost uniformly light brown but ocelli also whitish), with brown lower part of epicranium under rostral apex as well as subgenae and mandibles (vs. subgenae light), with yellowish to whitish labrum and area on each gena, and with more or less spotted clypeus and palpi as well as antennae; pronotum with brown lateral lobes and yellowish disc having few brown spots (vs. disc light brown with less distinct darkenings); legs and tegmina also spotted, but hind femur somewhat darker (almost brown, not more or less light brown) than in nominotypical subspecies, and tegmina with whitish areas between two lateral chords and between dividing veins of mirror as well as between R and Cu veins (vs. these areas almost transparent to yellowish); abdomen with more or less greyish brown tergites and anal plate, light greyish brown cerci as well as light brown sternites and genital plate, but latter plate with brown median stripe bifurcated along edges of posteromedian notch and running along posterior edges of posterolateral lobules (vs. this plate completely light brown but with whitish stripe along entire posterior edge; compare Figs. 1: L and 1: M); shape of genital plate in these subspecies also not identical, posteriorly more sinuate in new subspecies and simpler in nominotypical one (see Figs. 1: L and 1: M); genitalia with epiphallus having almost angular [not rounded] posteromedian notch and more distinct short lateral projection near each subapical hook (compare Figs. 2: I and 2: M), and with rachis having lower and obtuse proximal lobe on right posterodorsal keel (vs. this keel with clearly higher proximal lobe having almost acute-angled distal projection; compare Figs. 2: L and 2: N).

Length in mm. Body 12; body with wings 13.5; pronotum 2.8; tegmina 9; hind femora 8.5. Female unknown.

Comparison. The new subspecies is distinguished from M. t. tabulophila , found in the Malay Peninsula mountains, by the characters listed above (in its description).

Etymology. The new subspecies name is the Latin word insularis (“insular”) due to the type locality of this subspecies.
