Hornburg, Michael, 2012, Nomenclatural changes in Neotropical Tracheini with the description of Hylaeogena aeneonitens sp. nov. (Coleoptera: Buprestidae) from the Orinoco basin in Venezuela, Zootaxa 3242, pp. 53-61 : 57

Hylaeogena speculum ( Klug, 1825)

( Figs. 3, 5 )

Trachys speculum Klug, 1825: 430 .

Brachys speculum: Saunders, 1870: 37 .

Pachyschelus speculum: Saunders, 1871: 134 . Hylaeogena speculum: Obenberger, 1925: 78 , 134, 143. Hylaeogena cordieri Obenberger, 1923: 43 . syn. nov.

In comparing the syntypes of H. speculum from ZMHB and the holotype of H. cordieri from NMPC, no significant differences were found, hence all examined specimens of both species are considered conspecific. During examination, one of the syntypes of H. speculum was found to be male, allowing the male genitalia to be illustrated for the first time ( Fig. 5 ).

Specimens examined:

ZMHB: lectotype (designated herein): 12132 [p] | Speculum / Brasil v. Olf. [h, green label] | Pachyschelus / speculum / Klug/ vermutlich TYP!! [h]/ Det. Hoscheck 1931 [p] | Hist.- Coll. ( Coleoptera )/ Nr. 12132 (1. Ex.) / Brachys speculum Kl. / Brasil., v. Olf./ Zool. Mus. Berlin [p, green label]; paralectotype (designated herein): Pachyschelus / speculum Klug [h]/ Det. Hoscheck 1931 [p] | Hist.- Coll. ( Coleoptera )/ Nr. 12132 (2. Ex.) / Brachys speculum Kl. / Brasil., v. Olf./ Zool. Mus. Berlin [p, green label].

NMPC: holotype: Conceigao ie/ Araguaya. Brs.[h] | TYPE [red label, p] | Hylaeogena / cordieri m. Type [h]/ Det. Dr. Obenberger [p] | Mus. Nat. Pragae [p]/ 2685 [h]/ Inv. [p, orange label].

Remarks:

The series of H. speculum (Klug) in the ZMHB originally contained three syntypes. Currently the series consists of two specimens. Only one of the specimens bears an original label with collecting data. During his work in the Berlin Museum in 1931, Hoscheck assumed this specimen to be the type-specimen and added a label with his suggestion, as it could be seen on the cited label-data above (vermutlich Typ = probably type). It is conceivably that one of the three existing specimens of the syntype series remained in Hoscheck’s collection, which was subsequently split into at least two parts: Institut Royal des Sciences Naturelles de Belgique, Brussels (ISNB) and Naturhistorisches Museum Basel, Switzerland (NHMB).
