Description of holotype. Male. Body length 15.8 mm, elongate, almost parallel-sided, strongly convex. Dorsal and ventral surfaces weakly shiny. Head brownish black, pronotum, elytra and all tibia reddish brown, antennae and tarsi paler ( Figs. 1A, B ). Dorsal surface of frons and margins of pronotum covered by strong, very long yellow macrosetae; clypeus, pronotal disc, scutellum and elytra covered with recumbent, short, fine, yellowish macrosetae; ventral surface of thorax and abdomen with recumbent, long, yellow macrosetae. Head, appendages, and legs covered with moderately long, yellow macrosetae. Macropterous.

Head. Labrum transverse, bilobed; lobes rounded, randomly weakly punctate, covered with long, erect macrosetae. Head including clypeus semiglossy, deeply punctate, setae on frons markedly (10 times) exceeding puncture diameters. Clypeus broadly rounded, deeply concave in spoon-like fashion, apical third impunctate, basally deeply punctate. Frontoclypeal suture gently undulate. Occipital carina present, highly elevated, slightly curved forward, apical side perpendicular to basal side, both sides deeply puctate, frons covered with strong, long macrosetae, head covered by short, fine macrosetae ( Figs. 1A, B, E, H ). Occiput moderately punctate. Canthus narrow, short, glabrous. Combined width of both eyes approximately equals minimum width of frons between eyes, eye distinctly extending beyond canthus. Antenna with 9 antennomeres; club with 3 antennomeres, almost straight, distinctly shorter than antennal shaft (antennomeres 1–7 combined).Antennomeres 1 and 2 with sparse, long macrosetae; club with sparse, short macrosetae ( Fig. 1H ). Terminal maxillary palpomere expanded medially, shorter than palpomeres 2 and 3 combined.

Pronotum. Transverse, widest behind middle of its length. Anterior margin straight, with angles extended forward. Lateral margins crenulate and macrosetose. Base without border; medially gently arched toward elytra, with smooth margin paralleled by row of coarse punctures, with very long, dense macrosetae; hind angles broadly round- ed. Central part of pronotum with weakly indicated longitudinal keel. Entire surface evenly punctate, each puncture with a semirecumbent macroseta twice as long as puncture diameter (only few setae preserved in this specimen). Distance between punctures of 2–3 times puncture diameters, surface between punctures shagreened ( Figs. 1E, H ).

Scutellum. Large, with semirecumbent macrosetae, almost equilaterally triangular, sides and apex rounded.

Elytra. Strongly convex, parallel-sided, rounded apically, apical angle approximately rectangular. Striae absent except for the weakly indicated sutural stria. Humeral umbones present, weakly swollen. Surface with deeply macrosetose punctation similar to that on pronotum, surface between punctures shagreened and in posterior part finely punctate ( Figs. 1A, B ). Epipleuron distinct, complete, narrow, laterally with recumbent yellow macrosetae twice as long as puncture diameters, punctures coarse, almost evenly spaced, separated by twice their diameter.

Legs. Femora narrow, shiny, irregularly punctate, macrosetaceous. Protibia narrow, distinctly tridentate, terminal spine inserted anteriorly of medial tooth. Mesotibiae and metatibiae slightly expanded distally, with two pointed macrosetiferous longitudinal carinae. Upper terminal spine of metatibia flattened, slightly curved, acute apically, almost as long as the lower spine, which is truncate at apex and chisel-shaped. Claws bifid, with ventrobasal teeth ( Fig. 1C ).

Abdomen. Ventrum covered only by long, semierect, yellow macrosetae. Tergite 8 (“pygidium”) lightly trans- verse, convex, bordered all around, broadly rounded apically, unevenly covered by coarse umbilicate, macrosetiferous punctures, between punctures shagreened ( Fig. 1D ).

Male genitalia ( Figs. 1F, G ). Aedeagus symmetrical, parameres longer than phallobase, evenly curved in ventral aspect, apically curved and pointed in dorsal aspect; macrosetae absent.

Variability in males. Paratypes 12.0–16.0 mm long, slightly variable in density of dorsal punctation and length and in distribution of macrosetae. Frontoclypeal suture going from straight to gently undulate. Colour as in the holotype.

Sexual dimorphism. Female differs from male in the following characters: body length 14.0–16.5 mm; antennal club shorter; distal protibial tooth wider and longer; elytra widest in apical half; metatibia more strongly expanded distally; tarsomeres of all legs shorter.

Distribution. Lebanon ( Fig. 4 ), Syria and Israel.

Differential diagnosis. Haplidia karlaeschneiderae Sehnal, Montreuil & Uliana , new species, belongs to the “ Haplidia fissa group” ( Baraud 1988) and differs from other species in microsculpture (shagreened or not) of the pronotum, elytra and tergite 8, and morphology of the aedeagus.

Etymology. Patronymic, named in honour of Karla Schneider (MLHU), who provided us with the type of Haplidia fissa .

Remarks. This species was recorded from Lebanon, Syria and Israel ( Baraud 1988; Chikatunov & Pavlíček 1997; Montreuil 2005) under the name Haplidia fissa . Examination indicates that the type housed in MLHU belongs in fact to the genus Medeotrogus Keith, 2001 (Sehnal, in preparation) and that the Lebanese Haplidia recorded under this name in recent papers belong to a species which was undescribed, and here named Haplidia karlaeschneiderae Sehnal, Montreuil & Uliana , new species.
