Variability. Most O. dentipennis specimens examined by Moravec (2016) have a black-copper body, which corresponds with the original description given by Germar (1843). Only two specimens previously examined (a female from Angra dos Reis— Moravec 2016, 2018; and a male from Macacú— Huber 2012) presented the elytra with a bluish tinge. The specimens examined herein presented a bright blue coloration in the entire body ( Fig. 1–2 ), and a black abdomen with a reddish somewhat membranous median areas in females ventrites III-V ( Fig. 5–6 ), thus adding this variability to the species coloration. It is not clear if these differences in coloration are the result of distinct preservation methods. It is also noteworthy that most of specimens examined herein have a distinctively long elytral spine, known previously only for a female from Angra dos Reis ( Moravec 2016, 2020).
