Figs 42–44

MATERIAL. Holotype – ♂, Malaysia: Borneo I., Sabah State, “Pensiangan env.”, 4º34.948ʹN, 116º19.935ʹS, 516 m, 27.V–2.VI 2014, E. Shcherbakov.

DESCRIPTION. Male. General appearance very similar to that of previous congener ( X. mada ). Coloration yellowish with light brown narrow stripe on tegmen along proximal two thirds of anal edge, several small spots of same color on distal half of lateral tegminal field, a pair of dark brown dots on apices of inner and outer apical lobules of hind femur, and brownish areas on long spines of fore tibia and on subapical segment of all tarsi. Body structure as in X. mada but with differences in shape of some morphological structures of abdominal apex: last tergite with a pair of much less deep posterior notches and with unpaired posteromedian process rather small and asymmetrical, i.e. latter process having almost triangular distal plate with vertical ventral part and with rest part directed obliquely upwards/laterally; basal part of this plate with two small ventral projections directed downwards and in opposite sides ( Figs 42, 43 ); epiproct rather wide in dorsal (proximal) half and narrow in ventral (distal) part ( Fig. 43 ); cerci also with asymmetrical distal parts,

i.e. left cercus with widened lamellar plate at apex having two small teeth on its ventral edge, and right cercus with such plate smaller and lacking ventral teeth but having rather long apical spine ( Fig. 42 ); genital plate with apical part between styles roundly angular and more projected backwards than in X. mada ( Fig. 44 ).

Female unknown.

MEASUREMENTS. Length (in mm). Body 10.7; body with wings 22.5; pronotum 3.9; tegmina 18; hind femora 10.5.

COMPARISON. The new species is clearly distinguished from all the other species of Xiphidiopsis s. str. mainly in the characteristic structure of posteromedian process of last male tergite (especially in the clearly asymmetrical triangular shape of its distal plate).

ETYMOLOGY. The new species is named after its collector, entomologist E.O.

Shcherbakov.
