The Anomala linwenhsini -species group Four of the new species from Taiwan described in the present paper, i.e. A. linwenhsini Zhao & Zorn, new species, A. wutaiensis Zhao & Zorn, new species, A. kanshireiensis Zorn & Zhao, new species and A. inclinata Zhao & Zorn, new species comprise a homologous group. They are characterized by the combination of the following characters: body moderately convex, anterior margin of clypeus distinctly reflexed, elytral intervals strongly convex, strial punctures dense and large, lateral carina indistinct, epipleura with a row of long setae, protibia distinctly tridentate in both sexes, metatibia rather slender and not fusiform, parameres fully separated and more or less asymmetric, scutellar surface and disc of pronotum before scutellum with few short to long erect setae. The latter setae have so far not be found in all examined specimens, and the authors are uncertain at this point whether they are worn off in these cases or not present in all specimens. Anomala inconcinna Bates, 1888, also only known from Taiwan, is superficially very similar to the species of the linwenhsini -group. However, in A. inconcinna the protibia is clearly bidentate, it does not have singular long setae on pronotum or scutellum, the epipleural setae are slightly shorter, and the aedeagus is more or less symmetric. Therefore, the authors currently do not include A. inconcinna in the linwenhsini -group. |
