Pridonius Blackwelder 1952  Edit

Pridonius Blackwelder 1952: 321  Edit , as subgenus of Quedius Stephens, 1829  Edit (new name for Prionidus Bernhauer  Edit ). Type species: Quedius iheringi Bernhauer, 1907  Edit , by autotypy.

= Prionidus Bernhauer 1907: 287  Edit , as subgenus of Quedius Stephens, 1829  Edit (preoccupied, not Uhler 1886 ( Hemiptera  Edit )). Type species: Quedius iheringi Bernhauer, 1907  Edit , by original designation.

Notes: as valid genus, not subgenus of Quedius  Edit , moved to Philonthina  Edit ( Chani-Posse et al. 2018). Pridonius  Edit is a Neotropical genus, currently with only three species known from Brazil.

Pridonius iheringi ( Bernhauer 1907)  Edit

Quedius (Prionidus) iheringi Bernhauer 1907: 287  Edit . Type locality: Jundiahy, San Paolo, Brasilien. Type depository: FMNH 1 ST. Distribution: Brazil (São Paulo). Notes: comb. nov. ex Quedius  Edit , moved to Philonthina  Edit (Chani- Posse et al 2017).

Pridonius penetrans ( Silvestri 1946)  Edit , comb. nov. ( Figs. 47–48)

Belonuchus penetrans Silvestri 1946: 522  Edit . Type locality: Campo Grande , Mato Grosso, Brasilia [ Brazil]  Edit . Type depository:? #? ST. Distribution : Brazil (Goiás, Mato Grosso)  Edit . Notes: “doubtfully termitophilous species” ( Seevers 1957); distribution within Brazil (Asenjo et al. 2013).

Remarks. Silvestri (1946) described B. penetrans  Edit based on specimens from Brazil. We have not seen the original material but we have no doubt that the specimen here examined is the species that Silvestri described, as interpreted later by Seevers (1957). This species, on the other hand, does not belong to the ‘ Belonuchus haemorrhoidalis  Edit clade’ but it is congeneric with the two currently known species of Pridonius Blackwelder  Edit , i.e., P. iheringi (Bernhauer)  Edit and P. sparsiventris (Bernhauer)  Edit .

Material examined. Specimen ♂ ( FMNH, Figs. 47–48): mounted together with dissected genitalia, “Weiserianum?” [in Newton’s hand] det. Newton 1992 (white label)// “? Scaripaheus penetrans  Edit ” [in Newton’s hand] det. Newton 1996 (white label) // A. Newton Collection (green label) // BRAZIL: SP, Sao Paulo, 9.XI.1970, V. N. Alin (white label)”.

Pridonius sparsiventris (Bernhauer 1917)  Edit

Quedius (Prionidus) sparsiventris Bernhauer 1917e: 92  Edit . Type locality: Ypiranga, Brasilien. Type depository: FMNH 2ST; MZSP? 1+ST. Distribution: Brazil (São Paulo). Notes: comb. nov. ex Quedius  Edit , moved to Philonthina  Edit ( Chani-Posse et al. 2018).
