Malachius fulvicollis Gebler, 1844: 99 Type locality: Guriev (now Atyrau), Kazakhstan Paratinus fulvicollis: Abeille de Perrin, 1891: 214, 223–224

= Apalochrus maculicollis Motschulsky, 1860: 118 .— Solsky, 1872: 185 –186; synonymized by Evers, 1987: 12. = Apalochrus maculicollis Peyron, 1877: 269 , 274; junior homonym of Apalochrus maculicollis Motschulsky, 1860 : Greiner, 1937: 166; Mayor, 2003: 90; 2007: 416.

Note. Apalochrus fulvicollis Gebler, 1860 is a different species from Apalochrus fulvicollis Gebler, 1844 and has been synonymized by Abeille de Perrin (1891: 224) with Apalochrus flavicollis Schaufuss, 1870: 157 .

The synonymy of Apalochrus maculicollis Peyron , as suggested by Greiner (1937: 166) and listed by Mayor (2003: 90 and 2007: 416) is here accepted.

Redescription. Male. Head black without metallic lustre; clypeus, mandibles, genae and labrum, basal parts of mouthpart segments including palpi, antenna (except a black spot on the tip of apical antennomere), tibiae, tarsi, apical third of anterior femora, anterior, intermediate and basal half of posterior trochanters yellow. Pronotum orange-yellow with a black, narrow and longitudinal stripe in the middle. Elytra black with blue-violet metallic lustre. Scutellum black with the same metallic lustre as elytra. Femora dark brown, lacking metallic lustre. Ventral side of thorax, coxae and abdomen black; borders of sternites widely yellow; sides of pronotum and vesicles yellow; thoracic mesepimera brown.

Head narrower than pronotum, slightly impressed just before clypeus, with a thin longitudinal wrinkle in the frons middle; surface evenly covered with thin, short, semi-erect, light brown pubescence, a row of long, black, erect setae on temple behind eyes, reaching the antennal base; surface coarsely punctate in anterior half and wrinkled on frons, microsculpture indistinct, bright; labrum transverse, covered with short, white, semi-erect setae; genae short, straight; eyes protruding, round. Maxillary palpi short, 1st segment large, triangular, approximately equal in length and apical width to the 3rd, 2nd small, transverse, 2.5 timer shorter than the 3rd, this one wide, securiform, truncate at apex, dull, covered with short, light, semi-erect pubescence and fitted with several long erect setae. Antennae long, reaching basal forth of elytra; 2nd segment very small, rounded, almost completely hidden by scape, 1st antennomere conical, slightly widened at apex, 3th–6th segments cylindrical, not swollen, similar to each-other in length, 5th–6th more strongly sinuate at base, 7th–10th rectangular with sinuate base, equal in length and width, apical segment almost completely conical with sinuate and pointed tip. All segments covered with thin, pale, very short, sparse and semi-erect pubescence.

Pronotum approximately square, slightly sinuate at base before the middle, anterior margin very slightly convex, posterior straight, all angles rounded: anterior angles almost right, pronotum slightly depressed at basal fifth; discal surface smooth, bright, sparsely punctate with indistinct microsculpture pronotum on sides and near hind angles densely punctured, with distinct microsculpture; pronotal surface covered with double pubescence: uniform, light, short and depressed, and a row of sparse, long, black and erect setae hairs along anterior margin.

Scutellum transverse-rectangular, small, almost completely hidden by pronotum, with arcuate anterior margin; surface bright, densely punctate and microsculptured, covered by fine brown and depressed pubescence.

Elytra parallel, narrow, weakly widened posteriorly; shoulders distinct; apices evenly rounded, simple, lacking impressions or appendages; surface dull, densely punctured at base and shagreened elsewhere, evenly covered with fine, short, pale, semi-erect pubescence and sparsely with erect, dark and long setae.

Legs not long, thin, posterior femora reaching the apical fifth of the elytra, covered with very short, light, depressed, sparse and brown setae. Tibiae thin, evenly expanded posteriorly, rounded. All tarsi, narrow; claw segment slightly depressed dorsally, larger than the previous ones, as long as 3rd and 4th taken together, somewhat shorter than 1st and 2nd. Claws narrow, slightly curved, sharp, with a small rounded basal tooth.

Apical sternite ( Fig. 25 ) narrow, transverse, 2 times wider than long, distinctly divided into two lobes coupled with a transparent membrane, each lobe fitted with sparse, long, strong and dark setae; apical tergite ( Fig. 24 ) approximately semicircular, 1.3 times longer than wide, covered with sparse black setae. Median lobe ( Figs. 26 ) simple, very slightly curved ventrally, almost completely straight, with short stretched and slightly widened lamella evenly curved ventrally; internal sac with a set of three small denticles near apical part plus two large triangular denticles and a strong one respectively in basal and in part. Tegmen elongate, narrow, 2.4 times longer than wide, slightly emarginate at apical side and fitted with short thin appendages ( Fig. 27 ).

Length (male) 4.0– 4.7 mm, width (at elytral base) 1.0– 1.2 mm.

Female. Similar to male but antennae narrower and 1.5 times shorter; palpi 1.5 times narrower; elytra more strongly widened in posterior half, abdomen expanding outside elytra.

Length (female) 4.6–5.7 mm, width (at elytral base) 1.2–1.5 mm.
