TYPE SPECIES.— Eocnides assamensis Jeannel, 1954

DIAGNOSIS.— Adults of this genus ( Fig. 15a ) can be recognized by the following combination of character states: size large (BL = 4.8 to 5.2 mm); body form long and slender, fully-winged; eyes moderately large; frontal furrows deep; mentum and submentum fused or not; antennae long and slender; pronotum small, elytra long and flattened, discal striae partially effaced basally and laterally, with two discal setae present inserted in stria 3, umbilicate setae aggregated into humeral and median groups; legs slender; protibiae longitudinally furrowed; abdominal ventrites with long, very sparse pubescence medially in addition to two or more apical paramedial setae; median lobe of male aedeagus slender, the apex slightly recurved ventrally, endophallus with internal sclerite very long and tapered.

COMMENTS.— This genus was described by Jeannel (1954) based on a single female specimen, which he considered as close to genus Cnides Motschulsky (1862) , based on overall form and features of elytral sculpture. However, the discovery of a second species and two males allowed Uéno (1989) to find that the median lobe of the male aedeagus was formed as a closed tube, not at all open on its ventral face. He concluded that it should be considered as a taxon in subtribe Trechina and placed near the “ Trechoblemus ” and “ Trechus ” Complexes. We here recognize for the first time Agonotrechiotes Deuve (2010) as a junior synonym of Eocnides Jeannel (1954) .

GEOGRAPHICAL DISTRIBUTION.— This genus currently is known from only two species with a combined disjunct distribution including Assam (northeastern India) and Sichuan Province, China. The discovery of members of this genus in the study area in western Yunnan Province partially fills a gap in the distribution of the genus .
