( Figs 5–13 ).

DESCRIPTION. Female. Body length (from head to apical margin of tergum 2) 11 mm;

fore wing length 10 mm.

Head as wide as long in frontal view. Clypeus 1.5× as wide as long; its apical emargination

0.4× as deep as wide, taking about 1/2 of clypeal width, with single short blunt toot at center.

Vertex convex, longer than upper portion of compound eye, without cephalic foveae; distance between lateral ocellus and occiput 2.4× as distance between lateral ocelli. Pronotum without pronotal foveae, pronotal carina distinct, forming slightly acute, near rectangular angles at anterolateral corners of pronotum. Epicnemial carina strongly developed. Tegula nearly rounded posteriorly, with indistinct angle adjacent to parategula. Scutellum evenly convex.

Metanotum dorsally strongly impressed at center. Propodeum without shelf; propodeal concavity narrow, 0.7× as wide as T1 at base, with median carina along its entire length.

Propodeal valvula entire, unevenly rounded and forming blunt angle dorsoposteriorly. T1

0.4× as wide as long in dorsal view, evenly rounded in lateral view except its apex where slightly concave near posterior margin. T2–T5 evenly convex, with very narrow apical lamellae. S 2 in lateral view very slightly concave at center; posterior margins of S2–S5 with lamellae similar to those on corresponding terga. T6 and S6 narrowed towards blunt apex.

Clypeus reticulately, predominately longitudinally rugose, with shining interstices. Frons deeply punctured with shining interstices exceeding puncture diameter except black areas around antennal foveae where punctures larger and interstices matt, with distinct microsculpture. Gena punctured similarly as yellow part of frons but somewhat sparser. Vertex deeply irregularly punctured, with largest punctures approximately 2/3 as large as diameter of lateral ocellus and largest interstices exceeding puncture diameter. Dorsal and lateral parts of pronotum punctured as gena except dorsal black spots punctured similarly to vertex and anteriolateral black areas punctured similarly to areas around antennal foveae. Scutum punctured as coarse as vertex but punctures sometimes evidently arranged in longitudinal rows. Tegula shining,

with few small punctures. Scutellum punctured similarly to yellow parts of pronotum. Mesepisternum punctured in its yellow part as yellow parts of pronotum and in its black part as vertex.

Epicnemium matt, with microsculpture and few indistinct shallow punctures. Mesepimeron with punctures and indistinct longitudinal wrinkles in its upper part and with microsculpture below. Metanotum punctured as scutellum. Metapleuron longitudinally rugose with rows of punctures between wrinkles and matt interstices with microsculpture. Dorsolateral parts of propodeum punctured similarly to scutellum while lateral parts rather reticulate similarly to clypeus except transversely strigate black areas adjacent to valvula. Propodeal concavity transversely strigate, matt. T1 with dense irregularly scattered punctures, interstices exceed puncture diameter, rather shining. S1 matt, with indistinct sculpture. T2 with finer and sparser punctures than on T1, interstices reach several puncture diameters, with indistinct microsculpture. S2 with larger and somewhat sparser punctures than on T2, microsculpture more distinct. Punctation on T3–T6 finer than on T2, become indistinct towards apex of metasoma.

Punctation on S3–S6 become finer and denser towards apex of metasoma so that S6 completely matt and shagreened.

Setation weakly developed. Mandible with few strait pale setae as long as maximal diameter of flagellum. Posterior margins of T6, S4, and S5, as well as entire S6 with pale setae as long as diameter of F1 at base.

2 – habitus, lateral view; 3 – head, frontal view; 4 – labels.

Black with largely developed yellow pattern on clypeus (except black lateral margins),

frons (except black areas around antennal foveae), gena (except ferruginous lower margin),

scapus, dorsal and lateral parts of pronotum (except two dorsal black spots and anteriolateral black areas), most part of mesepisternum and upper part of mesepimeron, scutellum,

metanotum, dorsolateral parts of propodeum, lateral parts of propodeum (except black areas adjacent to valvula), fore legs (except black coxae and ferruginous tarsi), mid legs (except dorsal black spots on coxae and ferruginous tarsi), hind legs (except dorsal black spots on coxae, trochanters, and femora and ferruginous tarsi), T1 (except ferruginous dorsal midline and ventral margins), T2 (except large basal ferruginous spot), apical bands on T3–T5, nearly entire T6 (except black anterior margin), apical bands on T2–T4, lateral spots on T5.

Mandible (except black teeth), lower margin of gena, pedicel, entire F1–F3, F4–F9 ventrally,

tarsi, dorsal midline on T1, ventral margins of T1, and large basal spot on T2 ferruginous.

Wings slightly fuscous.

metasoma, ventral view; 10 – labels; 11 – genitalia, dorsal view; 12 – genitalia, ventral view;

13 – genitalia, lateral view.

Male. Body and fore wing length as in female. Structure resembles female but head 1.2×

as wide as long in frontal view. Clypeus 1.4× as wide as long; its apical emargination very small, 0.3× as deep as wide, taking about 1/5 of clypeal width, without toot at center. Distance between lateral ocellus and occiput 2.0× as distance between lateral ocelli. F11 slightly curved and bluntly pointed apically. T6 and S6 similar to previous segments. T7 with broadly and evenly rounded apex. S7 rather flat, with rectangularly rounded apex. Genitalia as in Figs 11–13 .

Parameral spine (gonostylus) reduced. Digitus without posterior process, curved anterioven-

trally, with acutely pointed distal lobe. Aedeagus robust, curved dorsally and broadened in lateral view towards apex.

Punctation as in female but clypeus distinctly punctured with deep sparse punctures and shining interstices exceeding puncture diameter. T7 punctured similarly to preceding terga.

S7 with very small but distinct punctures and rather shining interstices exceeding puncture diameter, with indistinct microsculpture.

Setation as in female but S4–S6 with broad basal fringes of dense appressed pale setae, in normal position hidden under preceding sterna. Posterior margins of these sterna, as well as those of T7 and S7 with sparse pale appressed setae, shorter than in female.

Coloration generally resembles female but mandible yellow (except black teeth), clypeus without black margins, pedicel and anterior face of F1 yellow, dorsal parts of pronotum without black spots, dorsolateral parts of propodeum with basal ferruginous spots, black color on entire legs and metasoma replaced by ferruginous (except anterior face of fore tarsi with yellow spots). T7 nearly entirely yellow (except ferruginous anterior margin). S7 completely ferruginous.

DISTRIBUTION. Turkmenistan (Alah Prov.).

BIONOMICS. Unknown.

DIAGNOSIS. The new species resembles Raphiglossa eumenoides S.S. Saunders, 1850

in its body size and proportions of T1 but strongly differs from it by having a narrow propodeal concavity which is less wide than T1 at base (versus approximately as wide as T1 at base),

anterior margin of clypeus deeply emarginated and with a single tooth at center in the female

(shared with Afrotropical species of the genus; versus not deeply emarginated and with two teeth at center in R. eumenoides ), and male genitalia with reduced parameral spine (gonostylus),

digitus lacking posterior process, and robust aedeagus, broadened in lateral view towards the apex (all three characters of genitalia shared with R. formosa Kostylev, 1940) and curved dorsally (unique feature; versus curved ventrally in R. formosa, according to Giordani Soika,

1974) (in R. eumenoides, parameral spine present, digitus has a posterior process, and aedeagus is narrow and curved ventrally).

ETYMOLOGY. The new species is dedicated to Alexandr P. Rasnitsyn, a famous Russian entomologist, in recognition of his great contributions to the systematics of Hymenoptera .
