Type material examined.

Hister brasiliensis Paykull, 1811: Lectotype, ♀, designated by Dahlgren in 1968, together with extracted genitalia glued to a rectangular mounting card, right foreleg missing, right elytron missing, right metatibia broken off, glued next to the specimen, with the following labels: “24” (pencil-written); followed by: "Uppsala Univ. Zool. Mus. / Gyllenhals saml. TYP nr. / 1153" (red label, printed); followed by: "LECTOTYP / HYPOCACCUS / BRASILIENSIS / PAYK. G. DAHL- / GREN 27.II.1968" (written in black ink) (UUZM).

Saprinus apricarius Erichson, 1834: Lectotype, present designation: most likely a ♀, pinned, left hind leg missing, with the following labels: "Aegypt / xxxxiv Er.(?)" (dark green label, written); followed by: “49233” (printed); followed by: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Aegypt., Ehrenberg / Zool. Mus. Berlin" (black-framed label, printed); followed by: " Saprinus / apricarius / Erichson, 1834 / LECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). Paralectotypes, present designation: 1 spec., possibly a ♀, pinned, with the following label: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Aegypt., Ehrenberg / Zool. Mus. Berlin" (black-framed label, printed); followed by: " Saprinus / apricarius / Erichson, 1834 / PARALECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). 1 spec., possibly a ♀, pinned, with the following labels: “49233” (printed); followed by: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Sicil, Dahl / Zool. Mus. Berlin" (black-framed label, printed); followed by: " apricarius / Er. / Sicil. Dahl." (black-framed label, written); followed by: " Saprinus / apricarius / Erichson, 1834 / PARALECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). 1 spec., possibly a ♀, pinned, with the following labels: “47”; followed by: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Sicil, Dahl / Zool. Mus. Berlin" (black-framed label, printed); followed by: " apricarius / Er. / Sicil. Dahl." (black-framed label, written); followed by: " Saprinus / apricarius / Erichson, 1834 / PARALECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). 1 spec., pinned, with the following labels: “54”; followed by: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Sicil, Dahl / Zool. Mus. Berlin" (black-framed label, printed); followed by: " apricarius / Er. / Sicil. Dahl." (black-framed label, written); followed by: " Saprinus / apricarius / Erichson, 1834 / PARALECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). 2 specs., pinned, with the following labels: "Hist. -Coll. ( Coleoptera ) / Nr. 49233 / Saprinus apricarius Er. x / Sicil, Dahl / Zool. Mus. Berlin" (black-framed label, printed); followed by: " apricarius / Er. / Sicil. Dahl." (black-framed label, written); followed by: " Saprinus / apricarius / Erichson, 1834 / PARALECTOTYPE 2014 / des. T. Lackner" (red label, written) (ZMHUB). This species has been described from both Sicily and Egypt, among the type series we designate a single female specimen from Egypt as lectotype to fix the taxonomic identity of the species.

Saprinus bistrigifrons Marseul, 1855: Lectotype, present designation: ♂, pinned, right mesotarsus missing, with following labels: tiny pink label, followed by: "161 / Saprinus / bistrigifrons / m. / Mexique / illegible text" (green, round label, written); followed by: "MUSEUM PARIS / COLL. / DE MARSEUL 1890" (green, printed label); followed by: “TYPE” (red-printed label); followed by: " Saprinus / bistrigifrons / Marseul, 1855 / LECTOTYPE 2014 / des. T. Lackner" (red label, written) (MNHN). This species has been described from unknown number of specimens and the lectotype designation fixes the species identity.

Saprinus dentipes Marseul, 1855: Lectotype, present designation: probably a ♂, pinned, left metatarsus and right hind leg missing, with the following labels: "160 / Saprinus / dentipes / illegible text / Mexique / illegible text" (round, green label, written); followed by: "MUSEUM PARIS / COLL. / DE MARSEUL 1890" (green, printed label); followed by: “TYPE” (red-printed label); followed by: " Saprinus dentipes / Marseul, 1855 / LECTOTYPE 2014 / des. T. Lackner" (red label, written) (MNHN). This species has been described from unknown number of specimens and the lectotype designation fixes the species identity.

Saprinus piscarius Blackburn, 1903: Cotype, sex unidentified, with printed label: "Australia / Blackb’s Coll" (printed), followed by " Hypocaccus / vernulus Blackb" (written), followed by " piscarius Bl. Cot. / vernulus placed with Cotype / piscarius in the Bl. Coll" (written), followed by " SAMA Database / No. 25-029592" (printed); 1 spec., " Hypo. piscarius / co-type" (written), followed by " SAMA Database / No. 25-029591 (printed)"; 1 spec., " Saprinus / piscarius / Cotype" (written), followed by " SAMA Database / No. 25-029590" (written) (SAMA). This species was described from 'near Adelaide’, as well as 'Also from Victoria (Frankston, Mr. Kershaw)' (Blackburn, 1903: 108). Because of the ambiguous label data (see above) as well as no locality indication of the cotype we decided not to designate a lectotype of this species.

Remarks.

Saprinus dentipes has been synonymized with H. (H.) brasiliensis by Mazur (1987). However, upon inspecting its type specimen we conclude that it is not synonymous with H. (H.) brasiliensis , but with the species Hypocaccus (Baeckmanniolus) gaudens (J.L. LeConte, 1851) instead. Thus Saprinus dentipes Marseul, 1855 = Hypocaccus (Baeckmanniolus) gaudens (J.L. LeConte, 1851) syn. n. H. (H.) brasiliensis is a widespread and variable species with variable dorsal punctation. The taxonomic status of both H. (H.) brasiliensis and the following H. (H.) sinae requires further clarification, especially with respect to their rather similar genitalia and minimal differences in dorsal sculpture. Hypocaccus (H.) brasiliensis is above included in the key to the Australopacific species of Hypocaccus that separates it from the related Hypocaccus (H.) sinae . We chose not to fully re-describe Hypocaccus (H.) brasiliensis here, leaving its re-description to the revision of the genus Hypocaccus . For the sake of the better species recognition, however, we decided to depict it here, including its male terminalia.
