DESCRIPTION
Head very long and wide (1.96/ 1.90mm). Facets very small; ocelli comparatively large (diameter 0.15 mm). Maxillary palp long and thin, apical segments of subequal length (0,33/0.36/ 0.39 mm). Three rows each with about 10 sensilla chaetica present at frons. Pronotum extremely short (0.47/ 1.96 mm); mesonotum with wing pads (0.74 central part/ 2.67 mm); metanotum (0.89 central part/ 2.97 mm).
Fore femora robust (1.28/ 0.5 mm) with two rows of four spurs each; fore tibia thin (1.19/ 0.15 mm) with numerous thick and strongly curved spurs; fore tarsi very long (0.42/0.36/0.21/0.19/ 0.36 mm), with dense sensilla chaetica in 10 rows (segment 4 with 4 × 10 sensilla chaetica). Mid femora robust and wide (width 0.5 mm), with strong terminal spur (12-14 helical ridges); mid tibia quite robust (1.75/ 0.24 mm) strongly carinated. Hind legs very long, with tibia thin (2.73/ 0.24 mm), carinated. Cercus very long (2.14/ 0.24 mm).
REMARKS
Free head with huge number of small eye facets indicate diurnal habits, supported by the reduced length of pronotum, enabling movable head. Elongated fore tarsi with numerous very large sensilla indicate strong sensorial function of legs, similar to earliest mantises. Nevertheless, its functional morphology remains obscure.
