Material examined. Holotype ♂ ( Fig. 1 A): Hungary, Verőce, 35 km N Budapest, (47º49.58'N 19º01.30'E), 21– 30.V.2005, Malaise trap, leg. Z. Nyiro (deposited in TUZ, ID: TUZ616003, secondary ID: BBSL 657480). Paratype 1♀ ( Fig. 1 B): Hungary, Verőce, 35 km N Budapest, (47º49.58'N 19º01.30'E), 28.VI–20.VII.2005, Malaise trap, leg. Z. Nyiro (deposited in TUZ, ID: TUZ616004, secondary ID: BBSL 662380).

Diagnosis. C. striatipleuris sp. nov. is very similar to C. semiauratus in shape and structure, except: middle and hind tibiae dark brown; metasomal terga without metallic lustre, occasionally on T5; mesopleuron with oblique striae ( Figs 2 D, 2E); male genitalia (as in Fig. 2 F). To date this species is thoroughly described by Móczár (2001: 924). A SEM picture of the mesopleuron is available in Móczár (2001: 911, Fig. 7), and another picture of the genital capsule is available in Rosa (2006: Plate I, Fig. 13), line drawings of the genital capsule are available in Móczár (1949: 275, Figs 22–23; 2001: 912, Fig. 17), and line drawings of the pronotum and mesosoma are available in Móczár (1967: 23, Fig. 2C ). Despite the existing earlier descriptions the species must be described as new in order to establish a new valid name for this taxon.

Description. MALE (holotype). Body length 6.5 mm, forewing length 4 mm.

Head. Height 1.1 mm, width 1.5 mm, shortest interocular distance 0.9 mm, malar space 1.4 times broader than high. Head colour metallic blue with some greenish tint. Head moderately punctate with interstices between punctures 1–2 PD wide and polished. Mandible blackish brown with proximal half metallic green. Scape green, the rest of antennae dark brown, nearly black. Relative lengths of P:F1:F2:F3 = 1:1.9:1.3:1.1. Pubescence on head dark brown.

Mesosoma. Length 2.6 mm, width 1.5 mm. Colour metallic blue with some greenish tint, propodeum posteriorly partly black. Pronotum similarly punctate as head with polished interstices of 2 PD wide. Posterior edge of pronotum with row of 4 large and few smaller foveae. Mesonotum sparsely punctate with polished interstices 2– 3 PD wide. Mesopleuron, especially on latero-ventral half, with numerous strigose and elongate foveae, largely fused forming oblique striae. Propodeum dorsally with rugose irregular carinae. Lateral propodeal teeth acute. Pubescence on mesosoma dark, brownish. Fore-femur greenish, rest of foreleg light brown, mid- and hind-legs dark brown with more or less green sheen on femora. Wing venation typical for Cleptes .

Metasoma. Length 2.7 mm, maximum width 1.7 mm, with five external segments. T1 and T2 testaceous, T3 testaceous proximally, slightly brownish centrally and dark brown distally, T4 and T5 black. Metasoma without metallic lustre except faint bluish sheen on T5. T1 polished proximally, without punctures, rest of the metasoma with small punctures with interstices 1–3 PD wide being sparser proximally and denser distally. Pubescence yellowish. Genital capsule (as in Fig. 1 F).

FEMALE (paratype). Similar to male holotype except for the following characteristics: relative lengths of P:F1:F2:F3 = 1:1.1:0.5:0.5; pubescence throughout yellowish; body colour, with head, pronotum, mesonotum, metanotum medially and frontal plus ventral part of mesopleuron metallic coppery-golden; rest of mesosoma metallic blue. Scape metallic coppery, pedicel brown, F1 and F2 yellow, F3 light brown, rest of antenna brown. Metasoma with four external segments. Forewing medially banded.

Remarks. The left mid-leg of the holotype is removed and deposited in TUZ for the extraction of DNA; the last flagellomere of left antenna of the holotype is missing.

Distribution. At present, the European distribution of C. striatipleuris sp. n. seems to be restricted to central and southern Europe. In fact, the English locality given by Móczár (2001), Torla, is actually in Spain, whereas the specimens listed Móczár (2001) for northern Europe ( Denmark) in ZMUC were later identified as C. semiauratus ( Paukkunen et al. 2014, sub C. pallipes ). Based on the pictures and descriptions given by Kimsey (1981) and Bohart & Kimsey (1982), the species is also distributed in the Nearctic Region.

Etymology. The specific name refers to the striate mesopleuron, one of the diagnostic characteristic valid for species identification when compared with the similar Cleptes semiauratus . It is an adjective in the masculine case based on the Latin stria (line) and the Greek pleuron (side).
