DESCRIPTION. Male. Head. Body dark-blue, slender, subcylindrical. Anterior margin of head wekly widely rounded; head widest at eye level; head width 1.6–

1.63× wider than interocular space; genae strongly rounded, weakly angulate; lateral margin of head without sinuation between anterior side and gena; anterior surface of head (frontoclypeus) depressed, with sparse and fine punctation (puncture diameter

2× wider than interpuncture distance); frons and genal surface with coarse and dense punctation of deep round punctures (puncture diameter subequal or longer than interpuncture distance); frons with unclear longitudinal elevation near eyes.

Antennae moderately long, with 3 apical antennomeres extended beyond base of pronotum. Comparative length: width of antennomeres 2–11 as following: 0.9:0.8,

3.6:1, 2:1, 2.1:1, 2:1, 2.4:1.1, 2.4:1.3, 2.:1.5, 2:1.5, 3.2:1.2. Head ventrally with very coarse and dense merged punctures, mentum strongly transverse.

Prothorax. Pronotum weakly transverse (1.15–1.18 times as wide as long), weakly cordiform, widest little before middle, 1.56–1.59 times as wide as head; lateral margins weakly rounded, weakly widely emarginate near base; anterior margin straight or weakly rounded; base straight at middle or evenly weakly rounded; anterior and posterior angles distinct, obtuse; disc moderately convex, sometimes with two round impression at middle, with oblique transverse impressions at sides of basal margin

( Fig. 9 ); all margins beaded, except for middle of anterior margin; prothoracic hypomera with large smoothed irregular wrinkles and small sparse granules in lower part; prosternal process convex, projected.

Pterothorax. Elytra elongate (1.56–1.65 times as long as wide), widest at middle,

1.95–2.02 times as wide as head, 1.23–1.31 times as wide and 2.4 times as long as pronotum; punctures is striae well expressed, elongate, 3–4 times larger than those in interstriae; striae sometimes weakly impressed, not expressed in apical third, where strial and interstrial punctures subequal; interstriae with fine sparse punctation; elytral apex not bifurcate, weakly convex along suture; epipleura with very fine and sparse raduliform punctures in base; mesoventrite granulated in anterior part; mesepisterna with raduliform wrinkles; mesepimera and metepisterna with simple coarse and dense punctation; metaventrite with coarse raduliform punctation (each puncture with small granule near anterior margin).

Abdomen. Abdominal ventrites 1–4 with raduliform punctation, 1st and 2nd ones with distinct granules near punctures, 3rd and 4th ones with weak granules; ventrite

5 with simple dense punctation.

Legs. Pro- and mesotibiae weakly curved; inner side of pro- and mesotibiae with strong reddish setae (but these setae not don’t form very dense narrow line) protarsi transverse, but weakly widened, not wider than tibiae at apex; comparative width:

length of protarsomeres 1–4 as following: 2.9:2.3, 3:2, 2.5:1.5, 2:1.1.

8, 9 – E. amri sp. n.; 7, 10, 11 – E. saphyrinus Allard, 1876. 1, 7 – male, habitus; 2 – aedeagus ventrally; 3 – aedeagus laterally; 4 – median lobe of aedeagus; 5 – VIII sternite; 6 – gastral spicula; 8, 10 – protarsus; 9, 11 – base of pronotum.

apical third, median lobe with one acute apex and additional inner baculi, male sternite VIII with very dense long brown hairs and additional sclerotized “spicules”

at middle; gastral spicula without lateral processes, lobes with additional sclerotization at middle.

Body length 10.8–13.5 mm, width 4–4.6 mm.

Female. Body more robust; antennae shorter, reaching base of pronotum; tibiae straight; protarsi not widened; lateral sides of pronotal disc very weakly depressed;

meso- and metatibiae with distinct elongate impression on lower side of apical third.

Body length 12.1–17.2 mm, width 4.9–6.9 mm.

COMPARATIVE DIAGNOSIS. The new species is most similar to Anatolian

Entomogonus saphyrinus Allard, 1876 ( Figs 7, 10, 11 ) by the granulated punctation of the metaventrite and partly prohypomera (Nabozhenko et al., 2018), but differs by the structure of male apical antennomere (elongate, not triangle as in E. saphyrinus),

the granulated prosternum, not granulated metepisterna, prothoracic hypomera with small granules only in lower part, pro- and mesotibiae with reddish (not black) setae on inner side, weakly widened pro- and mesotarsi, not impressed and not wrinkled pronotal disc along base, metatibiae without very dense narrow line of suberected strong setae and narrow (not widened) protarsi of male.

ETYMOLOGY. The species is named in honour of Prof. Zuhair Amr ( Jordan

University of Science and Technology), who made a great contribution to zoological studies of the Middle East.
