38) Eoxizicus (Axizicus) bifurcatus Liu sp. n.

Holotype ♂: TAIWAN N.: Tsaoshan / (Sozan) 200–300 m / 4–5.VIII.1963 / J. L. Gressitt / Collector

Diagnosis. General appearance typical of the genus. But male 10 th tergite with a small posteromedian notch, without a pair of median process ( Fig. 18b ). Male cerci with basal one third widen, apical two thirds bifurcated into 2 narrowed lobes in almost equal length, bending slightly upwards. Subgenital with 2 distinct longitudinal keels in bracket shape ( Fig. 18d ), posterior margin smooth, styli moderate long ( Fig. 18d ).

Female unknown.

Measurements (mm). Body: ♂ 12.1; Pronotum: ♂ 4.1; Tegmina: ♂ 17.7; Hind femora: ♂ 11.0.

Comparison. This species is very similar to Xizicus (Axizicus) falcatus Chang, Du & Shi, 2013 ( Figs.1 –8) from Taizhong, Taiwan, China, but male cerci is quite different, bifurcated much deeper, at one third of base (one third of apex in falcatus ), 2 branches nearly equal in length (inner branch much longer than outer one in falcatus ). Subgenital plate quite narrow with distinct keels, styli short. Epiproct short lobe with a distinct median furrow (long tongue shaped in falcatus ).

Etymology. Name referring to male cerci in bifurcated fork shape.
