Ultragryllacris pulchra alboclypeata Gorochov et Dawwrueng , subsp. nov.

( Figs 11–15 )

Material studied. Holotype—female; Thailand, Kamphaeng Phet Prov., Khlong Lan Distr., 1200–1350 m, 5 October 2013, coll. P. Pawangkhanant ( THNHM).

Description. Female (holotype). General appearance very similar to that of female of U. p. pulchra , but with following differences in colouration: head with whitish median ocellus, without asymmetrical darkened spot above median ocellus, with black transverse stripe between black borders of antennal cavities (each border with only ventral light interruption), with rather wide light interruption (rose stripe) between each black antennal border and each larger black area on dorsum, with additional black vertical stripe between each eye and each mandible, with light (yellowish white) clypeus, and with antennae having 5 proximal segments blackish and rest of antennal flagellum from reddish brown to light brown ( Figs 11–13 ); pronotum with completely blackish borders (including anteromedian part of pronotal disc; Figs 12, 13 ); legs with fore tibia slightly lighter in middle part, with middle tibia light but having two brown areas on basal part and slightly darkened apical part, and with hind tibia having basal part and spots on rest part somewhat darker, dark brown ( Fig. 14 ). Genital plate and ovipositor practically indistinguishable from those of nominotypical subspecies.

Male unknown.

Measurements (in mm). Length of body 29; body with wings 38.8; pronotum 6.85; tegmen 30.45; hind femur 18.35; ovipositor 24.55.

Comparison. The new subspecies differs from the nominotypical subspecies in the epicranium colouration (it is with black vertical stripes under the eyes) and in a very light clypeus.

Etymology. This subspecies name is produced from the Latin word “albus” (white) and from the Latin morphological term “clypeus” originating from the Ancient Greek word meaning shield.
