( Figs. 1–6 )

Holotype: 1♂, Shizuishan , Ningxia, 2003-VII-20, collected by Wang Wen-Qiang and Li Xin-Jiang.

Male Body medium in size, thickset, with hairs, especially on legs. Vertex short and wide, the width between eyes was about 2.0 times the diameter of eye; fastigial furrow distinct. Vertex of head depressed, with granular tubercles. Frontal ridge apparent, whole length with a groove, slightly projecting forward between the bases of antennae widened gently downwards, the widest near the base of labrum. Lateral facial carinae apparent. Eyes near elliptic, vertical diameter about 1.2 times longer than horizontal diameter. Antennae shorter, 22 segments, only reaching to the middle of pronotum, length of the middle segment about 3 times as width. Pronotum rough, with short subuliform projection, anterior and posterior margin angled protruding; the median carina elevated into lamellate and cut by hind transverse sulcus deeply than fore and mid transverse sulci; in metazoan the carina arclike raised, prozona longer than metazona slightly. Prosternum with a lamellate process on the anterior margin which emarginated in the middle part. Interspace of mesosternum lateral lobes trapezoid, wider, width of the narrowest part larger than width of broadest part of lateral lobes. Tegmina and hindwing developed, the apex reaching to the hind margin of 4th abdominal tergite, R vein with two branches, M vein with two branches, Cu vein without branch. Hind femur wide and compressed, its length about equal to 3 times of its maximum width; median carina of hind femur on upper side serrated. Hind tibia with 10 spines on outer side and 8 spines on inner side (including apical spine). Arolium between claws of tarsus larger, its apex reaching the middle of claws. Tympanal organ developed. Krauss’s organ near semicircle, surface with thinly rugose. Epiproct near tongue-like, with longitudinal groove in middle, wider at base. Cercus long conical. Subgenital plate short conical.

Coloration. Body browny. Hind femur filemot, with two dark bands on outer side, inner side dark blue in the middle area, inner genicular lobe red, lower area of hind femur on inner side red, inner margin of ventral aspect red. Inner side of hind tibia red on the base and end, purple on the middle. Hind tarsus yellowish brown.

Female unknown.

Measurement (in mm). Length of body: ♂ 26.1. Length of tegmen: ♂ 9.2. Length of hind femur: ♂ 13.1.

Diagnosis. The new species Eotmethis inditibialis sp. nov. differs from all known species of the genus by inner side of hind tibia purple in the middle.

Etymology The specific epithet is named for indi- purple, -tibialis meaning hind tibia purple in the middle in Latin.
