D e s c r i p t i o n: Body length 9.2 mm, length of fore body (to end of elytra)) 4.3 mm. Coloration: Head, pronotum and scutellum black, elytra orange-brown, first four visible tergites brown, posterior margin narrowly and whole tergite 5 red-yellow, tergite 6 yellow, maxillary and labial palpi yellow-brown, mandibles brown, antennomeres 1-2 and base of antennomere 3 brown-yellow, remaining antennomeres brown, legs yellow.
Head wider than long (ratio 38: 29), distinctly narrowed posteriad, posterior angles obtusely rounded, bearing two long and several short black bristles. Four coarse punctures between eyes, medial punctures distinctly shifted anteriad, distance between medial punctures six times as large as distance between medial and lateral puncture. Eyes large and slightly convex, distinctly longer than temples (ratio 18: 8), inner margin with four coarse punctures. Temporal area with several varying large punctures. Surface with traces of fine microsculpture.
Antennae slender and long, reaching posterior margin of pronotum when reclined. Antennomeres 1-3 and 11 distinctly longer than wide, antennomeres 4-5 slightly longer than wide, antennomeres 6-8 as long as wide, antennomeres 9-10 slightly wider than long.
Pronotum almost as long as wide, parallell-sided, anterior angles rectangular, bearing four long and three short black bristles, posterior margin markedly rounded, sides bearing several varying long bristles. Each dorsal row with six approximately equidistant coarse punctures, each sublateral row with three coarse punctures, punctures two shifted to the lateral margin. Surface with microsculpture similar to that on head.
Scutellum very densely and coarsely punctured, diameter of punctures larger than eyefacets, mostly of punctures contiguous.
Elytra wider than long (ratio 52: 47), widened posteriad. Punctation coarse and dense, diameter of punctures larger than that on scutellum, separated by one puncture diameter or slightly smaller. Surface without microsculpture; setation ginger-haired.
Legs. Metatibia longer than metatarsus (ratio 29: 27), metatarsomere 1 slightly longer than metatarsomere 5 and longer than metatarsomeres 2-3 combined.
Abdomen wide, from visible tergite III slightly narrowed anteriad and distinctly narrowed posteriad. First three visible tergites with two basal lines, elevated area between lines with scattered punctures. Punctures at base of tergites finer and denser than that on
elytra, becoming sparser and finer to the posterior margin of each tergite. Surface without microsculpture; setation similar to that on elytra.
Male. Protarsomeres 1-3 dilated and sub-bilobed, each covered with modified pale setae ventrally, protarsomere 4 smaller than preceding ones. Sternite IX (Fig.) aedeagus (Figs).
Female. Protarsomeres 1-3 less dilated than in male, protarsomere 4 small, all protarsomeres covered with modified pale setae ventrally.
C o m p a r a t i v e n o t e s Philonthus mandrillus is similar to P. pelecanus HROMÁDKA 2010 , may be distiguished by the wider head, denser and coarser punctation of elytra and by the differnt shape of the aedeagus.
E t y m o l o g y: The name of this species, a noun in apposition, is the Latin generic name of the African Mandrill Mandrillus sphinx (LINNAEUS 1578).
