The genus Cestradoretus Ohaus, 1912 was erected by Ohaus (1912) to accommodate a Madagascan Adoretini species, C. tenuirostris Ohaus, 1912. This genus is characterized by the adults having the apex of the labrum with a long, fine, acute process curved downwards. In the addition to the above mentioned paper, Ohaus (1912) also described C. acomys Ohaus, 1912 from Tanzania, and later moved Adoretus tarsatus Klug, 1855, described from Mozambique, to Cestradoretus (Ohaus 1916). Later, Machatschke (1965) described two species from Africa, C. freyi Machatschke, 1965 from Botswana and C. minusculus Machatschke, 1965 from Somalia, and Frey (1976) described C. clypealis Frey, 1976 from Somalia. Thus, Cestradoretus included six species, one from Madagascar and five from Africa.
1912年，奥豪斯（Ohaus）建立了Cestradoretus属，以容纳马达加斯加的一种阿多雷蒂尼（Adoretini）物种——1912年的细喙Cestradoretus tenuirostris。该属的特征是成虫的上唇顶端有一个细长、尖锐且向下弯曲的突起。除上述论文外，奥豪斯（1912年）还描述了来自坦桑尼亚的1912年的Cestradoretus acomys，后来又将1855年从莫桑比克描述的Adoretus tarsatus Klug移至Cestradoretus属（奥豪斯，1916年）。后来，马查茨克（Machatschke，1965年）描述了来自非洲的两个物种，来自博茨瓦纳的1965年的Cestradoretus freyi和来自索马里的1965年的Cestradoretus minusculus，弗雷（Frey，1976年）描述了来自索马里的1976年的Cestradoretus clypealis。因此，Cestradoretus属包括六个物种，一个来自马达加斯加，五个来自非洲。
