Key to species of Philomessor (Attumbrinus)

Note. Setae on inner margins of meso- and metatibiae may be sometimes glued together and indistinct in badly preserved specimens.

1 Posterior margin of pronotum in front of posterior angles broadly and deeply emarginate, posterior angles sharp ( Fig. 40 ). Punctation and pubescence on elytra uniform, setae equal in length and less erect ( Fig. 39 ). Terminal antennomere shorter than the three preceding ones combined ( Fig. 21 ). Apical portion of aedeagus slightly narrowed, with rounded tip ( Fig. 22 ), parameres broad and exceeding apex of aedeagus ( Fig. 23 ), anterior part of genital segment narrow, short and subquadrate ( Fig. 24 ). Female unknown. Body length 3.1 mm. Morocco. ........................................ P. (A.) henroti Růžička, 1996

– Posterior margin of pronotum in front of posterior angles not emarginate, posterior angles rounded ( Figs 26, 28 , 54 ). Punctation and pubescence on elytra of two kinds: short, dense and recumbent setae are intermixed with sparser long erect setae born on larger raised granules ( Figs 33, 35, 37 ). The erect setae at least twice as long as the recumbent ones ( Figs 34, 36, 38 ). Terminal antennomere either shorter (for P. lackneri : Figs 14, 15 ) or longer (for P. cloueti : Fig. 13 , and P. bolivari : Figs 50, 52 ) than the three preceding ones combined. ............................................................................................................... 2

2 Posterior margin of pronotum rectilinear, posterior angles subrectangular ( Fig. 54 ). Terminal antennomere as long as or somewhat longer than the four preceding ones combined ( Fig. 13 ). Two kinds of punctation on elytra little different ( Fig. 37 ), erect setae ca. twice as long as the recumbent ones ( Fig. 38 ). Inner margin of metatibia in the terminal third distinctly setose ( Fig. 53 ). Apical portion of aedeagus strongly tapering towards acute tip ( Fig. 25 ), parameres narrow and not reaching the apex of aedeagus ( Fig. 5 ), anterior part of genital segment very short and wide, rounded anterolaterally ( Fig. 12 ). Female unknown. Body length 2.8 mm. Algeria. ........... P. (A.) cloueti ( Portevin, 1907)

– Posterior margin of pronotum convex, posterior angles broadly rounded ( Figs 26–29 ). Terminal antennomere shorter than the four preceding ones combined ( Figs 14, 15 , 50, 52 ). Two kinds of the punctation on elytra distinct ( Figs 33, 35 ), erect setae more than three times longer than the recumbent ones ( Figs 34, 36 ). Inner edge of metatibia either smooth ( Fig. 51 ), or finely setose apically ( Fig. 49 ). ..................................................... 3

3 Pronotum distinctly narrower than maximum width of elytra combined ( Figs 28, 29 ), inner margins of metatibiae smooth ( Fig. 51 ). Terminal antennomere longer than three preceding ones combined ( Figs 50, 52 ). Male: metatibiae curved ( Figs 28 , 51 ), aedeagus in dorsal view regularly thickened and only in apical portion narrowed into short protuberance ( Fig. 3 ), in lateral view feebly S-shaped, parameres reaching the tip of aedeagus ( Fig. 4 ), outer margin of sternum VIII with small median excision ( Fig. 8 ), anterior part of genital segment short and wide, rounded anterolaterally ( Fig. 11 ). Female: protarsi simple, not dilated ( Figs 29 , 47 ), tergum X oval, slightly longer than wide ( Fig. 19 ), sternum VIII transverse with short triangular spiculum ventrale ( Fig. 18 ). Body length 3.4–4.5 mm. Morocco. ..................................................... P. (A.) bolivari Jeannel, 1936

– Pronotum as wide as ( Fig. 26 ) or slightly narrower ( Fig. 27 ) than maximum width of elytra combined, inner margins of metatibiae finely and densely pubescent in apical portion ( Fig. 49 ). Terminal antennomere shorter than or almost as long as three preceding ones combined ( Figs 14, 15 ). Male: metatibiae straight ( Figs 26 , 49 ), aedeagus in dorsal view narrowed in basal portion, widest in the middle and then in apical portion narrowed into long and sharp protuberance ( Fig. 1 ), in lateral view regularly arcuate ( Fig. 2 ), parameres not reaching the tip of aedeagus ( Fig. 1 ), outer margin of sternum VIII broadly and deeply emarginate ( Fig. 6 ), anterior part of genital segment wide, extremely elongated, trifid anterolaterally ( Figs 9, 10 ). Female: three basal protarsomeres dilated ( Figs 27 , 43 ), tergum X three times longer than wide ( Fig. 17 ), sternum VIII narrower with long spiculum ventrale ( Fig. 20 ). Body length 3.0–3.4 mm.
