( Fig. 24 )

Nitidula bourgeoisi Grouvelle, 1914: 47 . Mystrops gigas Kirejtshuk & Couturier, 2009: 62 ; syn. nov.

Material examined. Sඒඇඍඒඉൾඌ: 2 spec., not sexed ( MNHN), labelled: ‘MUSEUM PARIS / ÉQUATEUR / EL PELADO / 4150 M. D′ ALT. / P. RIVET 1903 [grey label, p] // JANVIER [p] // Nitidula / Bourgeoisi / Grouv. [hw Grouvelle]’. Notes. The specimens are labelled as holotype and paratype of ‘ Mystrops gigas ’ by Kirejtshuk.

Comments to classification. According to Gඋඈඎඏൾඅ- අൾ (1914), Nitidula bourgeoisi was described after six specimens from Ecuador. Through the kindness of Ms. Taghavian we were able to study photos of two syntype specimens from the MNHN. Ventral view of one specimen clearly displays the characteristic form of the metacoxal line on abdominal ventrite I, which allows placement of the beetle within the genus Mystrops Murray, 1864 .

Mystrops gigas from Ecuador was described by Kංඋൾඃ- ඍඌHඎK & Cඈඎඍඎඋංൾඋ (2009) without mentioning Nitidula bourgeoisi , and the types of the latter, labelled by Kirejtshuk as holotype and paratype of Mystrops gigas respectively, were not included in the type material in the original species description.Although we did not study the type material of M. gigas , it is evident from its original description, that both taxa are conspecific. Even though the types of Nitidula bourgeoisi were omitted from the type material of Mystrops gigas and cannot be therefore considered types of the latter, the name bourgeoisi Grouvelle, 1914 has priority over gigas Kirejtshuk & Couturier, 2009 and therefore, it is here considered as junior subjective synonym of Mystrops bourgeoisi ( Grouvelle, 1914) , comb. nov.
