External characters support this assignment: dorsal setae are simple and cut-off apically (compare Fig. 12K with Fig. 2d), elytra lack longitudinal striae except for sutural stria, and pronotum and elytra are yellowish in color. The specimens above seem to stand close to the Argentinian species C. argentina Miller, 1974 and C. hermani Miller, 1974 of the C. atra group defined by MILLER (1974). When compared with the genitalia drawings and descriptions provided by MILLER (1974) it seems that the specimens examined here represent an undescribed species. We are however leaving it undescribed, as it is likely introduced and a more detailed comparison with the American species would be necessary to diagnose the species properly. The presence of the species which is clearly an element of Neotropical fauna in Saudi Arabia is very unexpected. The first author discussed the problem with both collectors (J. Bezděk and D.

The presence of the species which is clearly an element of Neotropical fauna in Saudi Arabia is very unexpected. The first author discussed the problem with both collectors (J. Bezděk and D. Král) and with the person who mounted the specimens for NMPC (P. Pacholátko), and all of them excluded any possibility of mislabeling or mixing the Saudi Arabian material with Neotropical samples at any stage of the processing. Another alternative would be an unintended introduction of this species with some imported cargo. That could be facilitated by the fact that the species comes to light and may have been attracted to the cargo by strong lights usual in the cargo depositories and harbors. The introduction scenario is however called into question by the fact that both
