Type material examined
Saprinus interpunctatus Schmidt, 1885: Lectotype, designated by Vienna & Colla in 2003, ♂, glued to a mounting card, with following labels: “Sicilien / Ragusa” (written); followed by: “coll. J. Schmidt” (printed); followed by: “Zool. Mus / Berlin” (printed); followed by: “interpunctat. / Schm. Typ” (written); followed by: “Type” (brick-red label, written); followed by: “interpuncta / tus Schmidt” (double black-margined label, written); followed by: “♂” (written); followed by: “LECTOTYPUS / Hypocacculus (Nessus) / interpunctatus (Schmidt, 1885) / Vienna & Colla des., 2003” (red label, printed) (ZMHUB). Paralectotypes, designated by Vienna & Colla in 2003, 2 ♀♀, one lacks its left hind leg, the other one lacks its left metatibia, with following labels: “Sicilia / Baudi” (written); followed by: “Type” (brick-red label, written); followed by: “Zool. Mus / Berlin” (printed); followed by: “♀” (written); followed by: “PARALECTOTYPUS / Hypocacculus (Nessus) / interpunctatus (Schmidt, 1885) / Vienna & Colla des., 2003” (ZMHUB). Another paralectotype, designated by Vienna & Colla in 2003, ♂, with genitalia extracted and mounted in Canada balsam on a separate slide under the specimen, with the same “Sicilien/Ragusa” label like the lectotype, followed by: “Zool. Mus / Berlin” (printed); followed by: “Saprinus / interpunctatus Schmidt / Coll. Schmidt-Bickhardt” (printed); followed by: “♂” (written); followed by: “PARALECTOTYPUS / Hypocacculus (Nessus) / interpunctatus (Schmidt, 1885) / Vienna & Colla des., 2003” (ZMHUB).

Biology
Saprobiont, collected on carrion and dung alike; several Australian specimens were collected under stones or using traps.
Distribution
Australia: Western Australia (Fig. 753).
Remarks
This species consists of two subspecies: H. interpunctatus interpunctatus that is known from the above-mentioned countries and H. interpunctatus muelleri Colla, Gomy & Vienna, 2004 occurring in Kenya and southern Ethiopia. The two subspecies differ chiefly in elytral punctation and intervals among striae; furthermore there are differences in the punctation of pygidium and clypeus (Colla, Gomy and Vienna 2014). Hypocaccus (N.) interpunctatus interpunctatus is diagnosed above, as well as provided with a differential diagnosis that separates it from other Australopacific taxa. Most important differences between the Australopacific members of the genus Hypocaccus are outlined in the key to the subgenera above. We chose not to fully re-describe Hypocaccus (N.) interpunctatus interpunctatus 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.
