Current status. New synonym of Rhoptrispa dilaticornis (Duvivier, 1891) .

Remarks. Gressitt & Kimoto (1963) described this species in Rhadinosa Weise, 1905 and added that ‘This species lacks one of the principal characters of Rhadinosa , a long spine on the scape. Instead it has only a tubercle. However, it is otherwise very similar to species of the genus, …’. Chen et al. (1986) omitted this species.

Chen & Tʼan (1964) proposed Rodtrispa as subgenus of Dactylispa Weise, 1897 for species having small body length (below 3.5 mm), uniformly black body, short antennae with dilatated apical antennomeres, and scapus with apico-ventral tubercle. Würmli (1976a) revised the group, considered Rodtrispa as subgenus, and synonymized all Asiatic species under R. dilaticornis (Duvivier, 1891) . Chen et al. (1986) rised Rhoptrispa to genus rank and listed three species: R. arisana (Chûjô, 1933) , R. clavicornis Chen & Tan, 1964 , and R. dilaticornis . Borowiec & Sekerka (2010) followed Chen et al. (1986) but listed R. arisana as synonym of R. dilaticornis . Rodtrispa species are traditionally separated by the length of elytral spines. Recently we had an opportunity to examine larger series of Rhoptrispa from various parts of SE Asia and found that R. dilaticornis is rather polymorphic species regarding the shape and length of dorsal spines on elytra thus R. clavicornis is perhaps also only extreme form of the latter. Rhadinosa abnormis clearly belongs to Rhoptrispa and in our opinion is conspecific with R. dilaticornis (Duvivier, 1891) thus is being synonymized here. All Rhoptrispa species (including also several African species) are based on rather minute differences that are probably subject to local variation and are hardly applicable when specimens from various localities are involved. We consider Rhoptrispa as distinct genus separate from Dactylispa because of the general morphology and particularly the structure of antennae. The form of body is more similar to genera associated mainly with grasses such as Hispellinus Weise, 1897 or Rhadinosa Weise, 1905 . The genus is in need of complex revision to set the borders between taxa thus we leave other herein discussed taxa as valid.
