Storozhenkotettix amphinotoides ( Günther, 1939) comb. nov.

Diagnosis. Currently inseparable from the generic diagnosis.

Redescription. Vertex trapezoidal in dorsal view, approximately as wide as eye, forming low horns in anterior view. Frontal costa bifurcation at top of face. Paired ocelli in bottom third of face. Top of antennal groove at bottom margin of eyes. Antennae filiform, with 13 visible segments. Prozonal carinae long and parallel. Median carina present throughout length of pronotum, not significantly elevated. Interhumeral carinae diverging caudally. Pronotal surface covered with carinulae and small tubercles. Pronotal tip relatively narrow and bifurcated. Lateral lobes projecting outward. Lateral area of pronotum long and narrow. Tegmina and wings absent. Upper margin of fore femora elevated and tuberculated. Middle femora tuberculated. Hind femora robust, with strong lateral tubercles. First segment of anterior tarsus long with three pulvilli. First segment of hind tarsus with three equal blunt pulvilli. First and third segment of hind tarsus approximately equal in length.

Coloration and variability ( Fig. 4 ). Living specimens exhibit cryptic coloration matching the brown tones of the logs they usually reside on. The head, pronotum, and legs are mostly brown with dark brown to black streaks and patches. The antennae are predominantly yellow with some black patches. Yellow coloration is present in the area around the eyes, lateral edges of the pronotum, and parts of the hind femora. Both the color patterns and the morphology seem to exhibit minimal variability among the observed specimens.

Habitat ( Fig. 5 ). The species was observed in lower to upper montane forests, all with wet or humid environments or vegetation. Most individuals were observed on huge rotted tree trunks. Some individuals were collected on forest floors covered with thick litter. On the other hand, a few individuals were observed on branches and leaves of shrubs. The species seems to prefer partially shaded microhabitats as the individuals are mostly found along forest edges or disturbed parts of the forest. Disturbances are evident along their habitats, such as illegal logging, forest destruction for agricultural lands, and road development.
