Trichohoplorana Breuning, 1961

Trichohoplorana Breuning, 1961: 548; Breuning 1963: 534; Breuning 1978: 49; Löbl and Smetana 2010: 213. Type species: Trichohoplorana dureli Breuning, 1961, by original designation.

Trichhoplorana Breuning 1977: 115 (misspelling).

Ipochiromima Sama and Sudre 2009: 384 (replacement name for Mimipochira Breuning, 1982: 25); Löbl and Smetana 2010: 209. Type species: Mimipochira sikkimensis Breuning, 1982, by original designation. Syn. nov.

Redescription.

Head distinctly narrower than prothorax, frons with a narrow, median furrow extending from base of clypeus up to apical margin of pronotum; eyes coarsely faceted, lower lobes of eyes distinctly far away from each other and longer than genae; antennae slender, distinctly longer than body, scape strongly expanded before apex, pedicle distinctly longer than broad. Pronotum transverse, with a tubercle on each side, punctured, with a pair of subuliform tubercles at sides of middle; prosternal process broad, with a longitudinal depression in middle, procoxal cavities closed posteriorly. Scutellum linguiform. Elytra covered with black or brown spots and a series of black or brown spots along suture; disc elongate, distinctly broader than pronotum at base, gradually narrow from near apical third, punctured, with a pair of tubercles at base and near scutellum, with a pair of bumps behind the tubercles; humeral angles rounded and slightly processed forward. Mesocoxal cavities closed externally to mesepimera. Femora strongly clavate.

Diagnosis.

Trichohoplorana is very similar to Neacanista Gressitt, 1940 in having the pronotum with a tubercle at each side, with a pair of tubercles at the sides of the middle, the elytra with a pair of tubercles at the base and near the scutellum, with a pair of bumps behind the tubercles, and a strongly clavate femora. However, Trichohoplorana differs from Neacanista in having the antennal scape strongly expanded before the apex (gradually thickened before the apex in Neacanista ) and the pedicle distinctly longer than broad (broader than long in Neacanista ).

Distribution.

Bhutan, China, India, Laos, Nepal, Vietnam (new country record).

Remarks.

Breuning (1982) established Mimipochira for M. sikkimensis Breuning, 1982, but this genus was a junior homonym of Mimipochira Breuning, 1956. Hence, Sama and Sudre (2009) introduced the new name Ipochiromima . After comparing photographs of the holotypes of T. dureli Breuning, 1961 (Fig. 1A ) and M. sikkimensis (Fig. 1B, C ), we consider these two species as belonging to the same genus, based on above redescribed characters. Thus, we treat Ipochiromima as a junior synonym of Trichohoplorana .
