Holotype ♂ “Turkestan 25/2 899” “ sellula Slsk ded Splichal?” “ longicornis Bernh. Type” “Chicago NHMus M. Bernhauer Collection” “Holotypus 1990 ♂ C. ( Zonoptilus ) longicornis Bernhauer, 1903 | det. dr. Tóth L.” “ Coprophilus (Zonyptilus) pentatoma Fauvel, 1897 | det. M. Gildenkov, 2014” (FMNH). Discussion . The structure of the body and the aedeagus of the holotype of C. longicornis are identical to those of the lectotype of C. pentatoma . The holotype of C. longicornis differs only in having yellow apices of the elytra, which cannot be regarded as a sufficient reason to retain the validity of the species. Thus, the new synonymy is established: Coprophilus ( Zonyptilus ) pentatoma Fauvel, 1897 = C . ( Z .) longicornis Bernhauer, 1903 , syn. n. Remarks . A detailed discussion on C. longicornis as a valid species and the illustrations of its aedeagus ( Tóth 1991: 97 ), which are allegedly different from the illustrations of the aedeagus of C. pentatoma ( Tóth 1991: 100 ) , should be regarded as erroneous.
