200A8781FFD9F35600F09073977E21EE.taxon	discussion	Remarks. Apparently, Frey did not take into account the insufficient and obscure description of O. clermonti based on one female and did not examine the holotype of the former. In the original description (Frey 1971) he compares O. parvidens with O. deflexicollis Lansberge, 1883. The type series of O. clermonti is comprised only of the holotype female, therefore it is not possible to examine the critical structures of the aedeagus for species identification in Onthophagus. However, I conclude that the holotypes of O. clermonti and O. parvidens are conspecific because they share the same principle diagnostic character states of external morphology (e. g. the groundplan of the head, coloration, pronotum punctation, etc.). Moreover, both type series were found at the same locality Hoa-Binh in Vietnam.	en	Tarasov, Sergey I.

200A8781FFD8F35600F094309613258E.taxon	discussion	Remarks. I have examined large material of O. cognatus and similar species from Indochina. Onthophagus cognatus is widespread in Indochina and can be easily separated from similar species by external characters and structure of the aedeagus. Although I have not examined type specimens of O. chulapornus Masumoto, Ochi & Hanboonsong, 2008, the original description of this species is well illustrated with a photograph of the holotype and illustration of the aedeagus. These illustrations match the character states seen in O. cognatus and lead me to conclude that these names should be synonymized. It seems that O. chulapornus was described as a new species simply because the authors did not know the identity of O. cognatus. Likewise, the lectotype of O. jucundus was examined and matched O. cognatus in diagnostic external and aedeagal character states and these names are here synonymized.	en	Tarasov, Sergey I.

The lectotype is designated in order to preserve the stability of zoological nomenclature according to the article 74.7 (ICZN 1999).

200A8781FFD8F35500F091D09137204E.taxon	discussion	Remarks. It seems that Frey (1971) did not thoroughly examine the description of O. gracilipes and did not see the type series of the former. In the original description he compares O. laosensis with O. troniceki Balthasar, 1933. The type series of Frey’s O. laosensis includes only a female holotype, however that was not an obstacle for identification because the type series of O. gracilipes includes a female. I synonymize these two names because the type series of O. laosensis and O. parvidens are conspecific based on their same principle diagnostic character states of external morphology: the unique color pattern of the elytra and body, the unique groundplan of head, and the identical pattern of pronotum punctation. Additionally I have examined large material of O. gracilipes from other localities in Indochina and these also match the two series of both names in the characters detailed above.	en	Tarasov, Sergey I.

Tarasov det. 2009 [printed] Additional material examined: 1 ♂ (MNHN) bearing the same geographical label as the holotype and labeled by someone later as a paratype of O. perroti Paulian, 1978. The original description of O. perroti was based on a single specimen (Paulian 1978) and therefore this paratype label is erroneous.	en	Tarasov, Sergey I. (2010): Seven new synonyms within the genus Onthophagus (Coleoptera: Scarabaeidae) from the Oriental Region. Zootaxa 2566: 45-48, DOI: 10.5281/zenodo.197274
200A8781FFDBF35500F0949091A725EE.taxon	discussion	Remarks. Based on my observations, O. perroti represents individuals exhibiting the minor form of the earlier described and common Oriental species O. orientalis Harold, 1868. The character states of external morphology of O. perroti (e. g. vertex horn, pronotum punctation, etc.) are compatible with the range of variation of O. orientalis. Morover, the holotype of O. perroti has the same aedeagus as the lectotype of O. orientalis.	en	Tarasov, Sergey I.

200A8781FFDBF35500F09030972C260E.taxon	discussion	Remarks. The examined paratype of O. demaak is conspecific with the type series of O. pseudojavanus because they share the same aedeagus, structure of the head, vertex horn, pronotum punctation and body coloration. It seems that O. demaak was described as a new species simply because the author did not know the identity of O. pseudojavanus.	en	Tarasov, Sergey I.

200A8781FFDBF35400F0925093A4230E.taxon	discussion	Remarks. The examined holotype of O. anamalaiensis is conspecific with the type series of O. pseudojavanus because they share the same aedeagus and principle diagnostic characters of the external morphology (structure of head and vertex horns, pronotum punctation, body coloration, etc.). Moreover, both type series were collected at the same locality in southern India. It seems that O. anamalaiensis was described as a new species because the author did not know the identity of O. vladimiri.	en	Tarasov, Sergey I.
