Chrysis (Chrysis) ashabadensis: Linsenmaier 1968: 85 , nec Radoszkowski, 1891: 183 ( Lebanon, without locality).

Diagnosis. Chrysis villosa Rosa , sp. nov. belongs to the C. elegans species group. It is characterised by having bicoloured metallic body, with green head and mesosoma and red to violet metasoma ( Figs 10A , 11A ); TFC, clypeus, pronotum, mesopleuron and scutellum with golden-red reflections ( Figs 10A , 11B ); green anterior declivity of tergum I; extremely elongate setae all over the body ( Fig. 10E ) (3.0 × MOD laterally on mesosoma and metasoma and 4.0 × MOD ventrally on all legs, including trochanters and sterna); general habitus stocky; TFC raised; female black spots distinctly separated ( Fig. 10E ); sharp genal carina; male genital capsule similar to those of the C. comparata species group ( Figs 11C , 14D ).

Material examined. TURKEY: holotype, Mut , 9.–13.vi.1965, ♀, leg. J. Gusenleitner ( NMLU) . Other material examined. LEBANON: Bcharre (N. Lebanon), 1670 m, 5.vii.1960, 1♂, leg. G.A. Mavromoustakis, det. W. Linsenmaier 1965 ( NMLU) ; Kadisha River (N. Lebanon), 1760 m, 22.vi.1960, 1♂, leg. G.A. Mavromoustakis, det. W. Linsenmaier 1965 ( NMLU) .

Description. Female ( Fig. 10 ). Body length 8.5 mm.

Head ( Figs 10B–10D ). OOL 1.6 × MOD; POL 2.0 × MOD; MS 1.0 × MOD; relative length of P:F1:F2:F3 = 1.0:1.5:0.8:0.7. Frons between the frontal carina and anterior ocellus with dense, small (PD about 0.3 × MOD) and contiguous punctures, without polished interspaces; punctures between ocellar triangle and eyes scattered, interspaces polished, about 1.0 PD; wider polished area postero-lateral to posterior ocelli; TFC raised, irregular; lateral ending close to eye margin; red TFC contrasting green brow and scapal basin; genal carina fully developed from temple to mandibular insertion; scapal basin micropunctate laterally, widely polished below the frontal declivity and medially, forming reverse, polished, triangular area; malar spaces short (1.0 × MOD); subantennal space 1.0 × MOD; apical margin of clypeus thick and brown, with triangular profile.

Mesosoma. Medial pronotal line extremely deep, as long as 2/3 length of pronotum; pronotum depressed in anterior half, depression converges on medial pronotal line; punctures on pronotum small, even, and interspaces with small dots; punctures on mesoscutum relatively small, similar to those on pronotum; on median area of mesoscutum more spaced antero-medially, without small dots and shallower on lateral areas; notauli formed by deep, subrectangular foveae; parapsidal signum deep and fully visible; punctures on mesoscutellum slightly larger than those on mesoscutum, interspaces shining; mesoscutellar-metanotal suture formed by deep punctures; punctures on metanotum deep, subcontiguous; posterior propodeal projections subparallel; mesopleuron with faint episternal, barely recognizable as a slight depression.

Metasoma. Punctures on terga I–III medially large and deep, almost contiguous; smaller laterally, with wider, polished interspaces ( Figs 10A, 10F ); median longitudinal carina barely visible on tergum II; tergum III without pre pit swelling; pits of pit row small, deep; lateral edge of tergum III with concavity before apical margin; apical margin slightly deflected, with dark brown rim ( Fig. 10F ). Black spots on sternum II large, as long as 3/5ths of segment length, close each other anteriorly, widely separated posteriorly ( Fig. 10E ).

Colouration. Head and mesosoma metallic green with extensive golden-red reflections on transverse frontal carina, clypeus, pronotum, scutellum, mesopleuron, and tibia; median area of mesoscutum black in the upper half; metasoma red to violet dorsally, anterior declivity of tergum I with contrasting green; flame red ventrally. Scape and pedicel green with golden-red reflections; flagellomeres dark brown. Tegulae non-metallic brown; wings slightly infuscate.

Vestiture. Malar space, vertex and gena with scattered, whitish setae (1.0–1.5 × MOD); mesosoma laterally and legs, including trochanters, with extremely long, erect and whitish setae, as long as 3.0–4.0 × MOD; metasoma laterally and ventrally with long (3.0 × MOD), erect and whitish setae ( Fig. 10E ).

Male ( Figs 11A–11F , 14D ). The associated male of Chrysis villosa Rosa , sp. nov., considered conspecific by Linsenmaier (1968 and in his collection, Fig. 11 ) has very small, subtrapezoidal black spots on sternum II, covering less than one third of the segment, and hairs slightly shorter. Genital capsule as in Figs 11C , 14D .

Distribution. Lebanon, Iran, Turkey ( Linsenmaier 1968).

Etymology. The specific name villosa (adjective, feminine) derives from the Latin adjective villosus, meaning hairy, in relation to the elongate setae covering this species ventrally.

Remarks. Linsenmaier (1968) included this species in the Chrysis elegans species group and identified it as Chrysis ashabadensis Radoszkowski, 1891 . However, we (P.R.) examined the type of Chrysis ashabadensis housed in Radoszkowski’s collection at ISEA-PAS (Rosa et al. 2015) and it turned out to be a member of the C. succincta species group, closely related to Chrysis coa Invrea, 1939 . The original description given by Radoszkowski (1891) was misleading because C. ashabadensis is the largest species in the C. succincta s.str. subgroup, and it shares with C. ashabadensis sensu Linsenmaier the general habitus, the edentate apical margin of tergum III, and the body colouration. Without type examination, it was impossible to assign this species in any species group. Kimsey & Bohart (1991) placed Chrysis ashabadensis in the C. succincta group following Linsenmaier (1968) because they also had no access to Radoszkowski’s type material. We here describe the misidentified Chrysis ashabadensis sensu Linsenmaier (1959) with the name Chrysis villosa Rosa , sp. nov.

Chrysis villosa Rosa , sp. nov. is related to C. transcaspica Mocsáry, 1889 and they both belong to the C. elengans species group. Both sexes of C. villosa sp. nov. can be easily separated from the latter by extremely elongate setae all over the body ( Figs 10A, 10E , 11A, 11F ) (3.0 × MOD laterally on mesosoma and metasoma and 4.0 × MOD ventrally on all legs, including trochanters and sterna); general habitus stocky ( Figs 10A , 11A ) (in C. transcaspica the habitus is slender as in C. elegans Lepeletier, 1806 ( Figs 12A , 13A )); TFC raised ( Figs 10B , 11B ) (vs. hardly visible in C. transcaspica ( Figs 12B , 13B )); female black spots distinctly separated ( Fig. 10E ) (vs. black spots closer to inner margins ( Fig. 12E )); sharp genal carina (vs. faint); male can be easily recognised by the different genital capsule ( Figs 11C , 14D ), similar to those of the species in the C. comparata species group, as already mentioned by Linsenmaier (1968).

Chrysis villosa sp. nov. is similar to C. mirae sp. nov. ( Figs 5 , 6 ) and the female is separated by the shape of genal carina, curved at mid gena (vs. straight); subgena narrower; TFC strong and fully developed (vs. faint); post pit row area narrow, as long as 1 pit diameter or little more (vs. 2–3 × times pits diameter); setae laying down on tergum III dorsally (vs. setae erected); metasoma flame red to violet (vs. golden); male recognisable by different shape of black spots on sternum II (compare Figs 6F and 11F ); different genital capsule (compare Fig. 14C and Fig. 14D ).
