Description. FEMALE ( Fig. 53 View Figure ). Length 1.9–3.5 mm. Head in frontal view green ( Fig. 54 View Figure ) or with variably extensive coppery to reddish-violaceous lusters, most commonly on frontovertex, face above toruli and on parascrobal region, but sometimes with limited luster also on lower face and gena; frontovertex distinctly differentiated by difference in sculpture at level about two-thirds distance between toruli and anterior ocellus, with larger, more isodiametric and much finer reticulations (shallow but noticeably delineated by raised ridge) dorsad level compared to distinctly reticulate sculpture ventrad level, the sculpture between frontovertex and torulus in particular more transverse reticulate-imbricate; in lateral view lower face and gena posterior to malar sulcus similarly strongly sculptured and colored; in dorsal view OOL 1.1–1.7× maximum diameter of posterior ocellus. Antenna ( Fig. 59 View Figure ) variable in color, rarely entirely yellowish, but at least scape largely yellow, the pedicel and flagellum sometimes entirely dark (smaller females) but usually at least fl 2 –fl 4 yellowish and clava and apical three or four funiculars usually dark; fl 1 at least quadrate and usually slightly longer than wide, fl 4 slightly shorter than combined length of fl 2 and fl 3, and funiculars increasing in width and beyond fl 4 decreasing in length such that apical funiculars slightly transverse in dorsal view; apical funicular ventrally extending under clava as apically tapered, ventrally bare and shiny, finger-like projection to level equal with apex of clava excluding slender, terminal, setose, spiniform process. Mandible bidentate with two similar teeth ventrally and obliquely angled margin dorsally.

Pronotal collar in lateral view shallowly concave to flat ( Fig. 53 View Figure ) and in dorsal view not distinctly “shoulderlike” posterolaterally; mostly reticulate and green to bright coppery ( Figs 54, 55 View Figure ) except for much more finely sculptured, meshlike coriaceous to smooth, elongate-triangular region posterolaterally, the posterolateral regions usually mostly reddish-violaceous, though rarely green or often with some coppery or bluish luster, but with scattered distinct setae and with longitudinal inner margins differentiating quadrangular median sculptured region over length of collar, the median region mostly punctulate-reticulate to reticulate except extreme posterior margin often more finely sculptured. Mesoscutum ( Fig. 55 View Figure ) anteriorly between incomplete notauli similarly sculptured and colored as pronotum dorsomedially, but with much larger reticulations posteriorly and with broad reddishviolaceous band posteriorly along transscutal articulation extending onto lateral lobes; scutellar-axillar complex green with variably distinct and bright coppery luster to mostly coppery or reddish-violaceous except at least for green to bluish median crenulate region between axillae ( Fig. 57 View Figure ), axilla with reticulate dorsal surface longer than median crenulate region between axillae, and with obliquely angled posterior surface very finely meshlike coriaceous to smooth, and scutellum low convex to distinctively flat ( Fig. 53 View Figure ) and more or less uniformly punctatereticulate to reticulate ( Fig. 57 View Figure ), though reticulations sometimes smaller mesally or more elongate mediolongitudinally and more reticulate-imbricate laterally. Tegula variably extensively yellowish to brown. Macropterous; fore wing ( Fig. 60 View Figure ) marginal vein about 6.0–7.2× length of stigmal vein; apex of postmarginal vein extending to or slightly beyond apex of uncus; uncus ( Fig. 61 View Figure ) diverging from stigmal vein at or near apex so as to at most differentiate small, rounded stigma posterior to uncus, and apex separated from posterior margin of postmarginal vein by distance greater than width of postmarginal vein but less than maximum height of stigma plus uncus; costal cell ventrally with 2–9 setae within about basal third and rarely with 1 or 2 setae within about apical third; disc ( Fig. 60 View Figure ) with distinct brownish region behind venation except narrowly hyaline behind marginal vein mesally, with hyaline band within basal half of marginal vein extended posteriorly for at least half distance to medial fold as variably conspicuous tapered hyaline region, and with cubital fold and often membrane behind cubital fold variably extensively similarly or lighter brown, and with distinct brown setae, the setae at most only slightly shorter in hyaline regions, except for narrow bare band behind parastigma and about basal half of marginal vein, but dorsally without distinct bare band beyond stigmal vein ( Fig. 61 View Figure ); marginal fringe present except anteroapically beyond postmarginal vein ( Fig. 61 View Figure ). Prepectus extensively setose with short white setae. Mesepimeron ( Fig. 56 View Figure ) bare along posterior margin. Metapleuron ( Fig. 56 View Figure ) bare, with about ventral half reticulate and dorsal half smooth and shiny. Metasternum comparatively long, with base of mesocoxa distinctly anterior to, and apex of mesocoxa about level with base of metacoxa. Legs ( Fig. 53 View Figure ), including coxae, yellowish- to orangeybrown or with meta- and/or mesofemora and tibiae darker brown, but basal three tarsomeres of meso- and metatarsi white and apical two tarsomeres of all legs darker brown; metacoxa with at least 2 setae dorsobasally and usually with distinct patch of several white setae in larger specimens ( Figs 56, 58 View Figure ). Propodeum ( Fig. 58 View Figure ) with crenulate band along anterior margin recurved into posteriorly tapered, V-shaped crenulate-rugulose region on either side of complete median carina; panels otherwise smooth and shiny, and callus smooth and shiny; callus anteriorly and propodeal plical region laterally between foramen and spiracle variably dark reddish-violaceous to purple, though callus posterior to spiracle often variably extensively green, median sculptured region often coppery to green, and smooth region adjacent to medial sculptured region usually variably green or greenish-coppery to blue or purple depending on angle of light.

Petiole dark with at least slight green to bluish-green lusters, dorsally sculptured, and about 1.4–2.0× as long as median width. Gaster uniformly dark brown or basally with green to reddish-violaceous lusters; presyntergal tergites very finely meshlike coriaceous except posterior margins smooth and basal tergite usually with more obscure, effaced sculpture (base of Gt 2 often also variably extensively smooth depending on extent covered by Gt 1), with Gt 2 at least similar in length and often longer than Gt 1 or Gt 3 depending on extent covered by Gt 1.

MALE. Unknown.

Hosts. Type material was reared originally from the wood of cherry, likely Prunus avium  (L.) ( Rosaceae  ), infested with Scolytus rugulosus (Mueller)  (= Scolytus mediterraneus (Eggers))  ( Coleoptera  : Curculionidae  : Scolytinae  ) and Anthaxia  sp. ( Coleoptera  : Buprestidae  ).

Remarks. The original description includes line drawings of the female antenna and fore wing (Deluchhi 1962, figs 2, 3), and states that the species was described from the holotype and eight paratypes, of which Baur (2001) located all but one paratype. I examined four paratypes, all of which are covered with particulate matter and incomplete to varying extents. The gaster was missing from three and only two had one complete antenna each.

Although not given as part of the description, females of N. oulmesiensis  vary in how compressed the head and mesosoma appear, some female having these quite conspicuously compressed such that the dorsal surface of the mesosoma is almost flat ( Figs 53, 56 View Figure ). Specific status and putative features differentiating females from those of N. kansensis  are discussed under the latter species. Mitroiu and Andriescu (2008) noted that of the species with associated males, N. versicolor  and N. sexramosus  , males were much more common than females. It therefore seems unusual that males are unrecognized for such a relatively commonly collected species as N. oulmesiensis  . Although at least some of the shared features listed in couplet two of the key likely represent symplesiomorphies, several suggest N. oulmesiensis  (and N. kansensis  ) is more closely related to N. yemenensis  and N. vanharteni  than to N. brevipetiolus  and N. longipetiolus  . Based on this assumed relationship, the unknown males of N. oulmesiensis  therefore more likely have a ramose than a pedicellate flagellum. However, if with another type of flagellar structure they may not be readily associated with females or recognized as Notanisus  males.
