Comments on classification. Vazirani (1974, 1975) described both C. gibsoni  and C. spangleri  from the same light trap collecting in New Delhi. Both species were described twice (based on the same material), in two different publications. Vazirani only compared the two species to each other and to C. andamanicus  (= C. oblitus  ). Although the author was aware of the existence of C. freudei  (see Vazirani 1970), he was not able to see its holotype and only studied specimens from Sri Lanka, tentatively assigned to that species. We have compared the holotypes of all three taxa: C. spangleri  agrees in all details with the holotype of C. freudei  . The holotype of C. gibsoni  is a soft, not fully matured specimen—which explains its paler coloration; in addition to that, the soft median lobe was deformed (flattened) when mounted into a slide; however, after careful examination, the shape of the median lobe is assumed to be the same in C. gibsoni  and C. spangleri  (i.e. also in C. freudei  ), including internal structures, see Figs 47–48 View Figure . Minor differences between C. gibsoni  and C. spangleri  in elytral striation, as mentioned in the original description, undoubtedly represent intraspecific variability. Therefore, we establish the following synonymy: Copelatus freudei Guignot, 1955  = C. gibsoni Vazirani, 1974  syn. nov., = C. gibsoni Vazirani, 1975  syn. nov., = C. spangleri Vazirani, 1974  syn. nov., = C. spangleri Vazirani, 1974  syn. nov.

Distribution. Copelatus freudei  was described based on two specimens: male holotype from Bengal and female allotype from Sri Lanka. Subsequently, Wewalka (1975) added records from Bhutan and Bihar, Rocchi (1976) published the species from Bangladesh, and Rocchi (1986) added localities from Sri Lanka. Holmen & Vazirani (1990) also mentioned the species from the Maldives, Rocchi (2001) recorded the species under the name C. spangleri  from Assam, and finally Darilmaz & Ahmed (2016) published the first record from Pakistan. We confirm the occurrence of C. freudei  in the northern part of the Indian subcontinent and add the first country record from Nepal, and Indian state records from Rajasthan, Uttarakhand and Uttar Pradesh.
