( Figs 2D , 9 )

Psyrana (Psyrana) imitativa Gorochov, 2024: 739 .

New material examined. EAST MALAYSIA; Sabah State • 2♂; Maliau Basin Conservation Area, at Maliau Basin Studies Centre accommodation (Keruing); N4.73588 E116.97442; 17 November 2024, evening; attracted to light; coll. M.K. Tan; SBH.24.139, 147 ( ZRC) .

Remarks. Our specimens from Maliau Basin ( Fig. 9 ) show similarities with Ps. (Ps.) melanonota (Stål, 1876) from Sumatra and Malay Peninsula, Ps. (Ps.) imitativa Gorochov, 2024 from Mindanao ( Philippines) and Ps. (Ps.) simulator Gorochov, 2024 from Sabah (Borneo). The dark colouration and patterns on the pronotum most resemble Ps. (Ps.) melanonota , but our specimens differ from all three species by the dorsum of the head completely red, instead of having merely red patterns as in Ps. (Ps.) imitativa or limited to only the upper rostral tubercle. Each tegmen has a conspicuous reddish stripe along the proximal branch of the Sc vein, resembling those in Ps. (Ps.) imitativa rather than Ps. (Ps.) melanonota . The left stridulatory area of our specimens is mostly similar to that of Ps. (Ps.) simulator in the shape and relative size of the mirror, but is most similar to Ps. (Ps.) imitativa in the shape of the stridulatory file. The male cercus resembles Ps. (Ps.) imitativa and Ps. (Ps.) simulator more than Ps. (Ps.) melanonota by the shorter relative distance between the two apical and preapical teeth. The male subgenital plate resembles Ps. (Ps.) melanonota and Ps. (Ps.) imitativa by the apical notch deeper than that in Ps. (Ps.) simulator . These suggest that the three species and our specimens may possibly represent a single species or part of a species complex. Here, we tentatively identify our specimens as Ps. (Ps.) imitativa owing to the overall similarities in the stridulatory file on the left tegmen, cercus, and male subgenital plate.

Type locality. PHILIPPINES: Bazilan Island .
