DESCRIPTION. FEMALE. Length 0.75–2 mm. Head ( Fig. 14 View FIGURES 7 – 16 ) brownish-yellow, with a faint golden-green lustre mainly on frontovertex and interantennal prominence and with magenta glimmer on scrobal depression under some angles on light; maxillary and labial palpi yellowish-white. Antenna with scape yellow except dorsal margin slightly darker distally, the rest brown with pedicel and basal flagellomeres having green lustre under some angles of light. Mesosoma ( Fig. 14 View FIGURES 7 – 16 ) brownish-yellow to yellowish-brown similar to head, with scutellum and axillae bright-yellow, contrasting at least slightly with the more infuscated surrounding sclerites, and following areas brown to dark-brown: a spot on lateral corner of pronotum anterior to each spiracle, tegula, propodeum and in some specimens also dorsal surface of mesoscutum; convex anterior part of median mesoscutal lobe with a blue or bluish-green lustre and outer side of lateral lobe with a golden-green lustre under some angles of light, median concave region with faint magenta and bluish lustres anteriorly; prepectus light yellowish-brown in anterior third and contrasting silvery-white in posterior two thirds. Fore wing with brownish venation except median part of submarginal vein paler; infuscated in proximal part of basal and costal cells, and with two well delimited transverse infuscated bands (one band behind parastigma and basal half of marginal vein, the other behind stigmal vein and apical quarter of marginal vein) and a darkened apex—the result is an alternating pattern of 4 dark and 3 clear transverse bands (Fig. 19). Legs brownish-yellow except mainly brown last tarsomeres, posterior surface of fore femur, hind coxa and femur, a dark stripe along anterior surface of hind tibia and dorsal surface of mid femur, and darkened bases of fore and mid tibiae (mainly on dorsal and posterior surfaces). Metasoma with Mt1 brownish, Mt2 and apparently also Mt3 dirty-white, translucent, with anterior third of Mt2 tinged with brown, Mt4–Mt8 brown, with a faint golden-green and coppery lustre under some angles of light. Ovipositor sheath with a broad median pale-yellow to dark-yellow ring, brown only apically and basally.
Head shiny, almost polished, with areas of almost effaced finely alutaceous sculpture on occiput, lower face, gena, and temples; scrobal depression shallow and wide, subrectangular, imperceptibly merging into frons, in lateral view with slightly angular lower parascrobal region. Head with numerous setiferous pinprick-like punctures except on middle of frons and scrobal depression; setae on frontovertex and along internal eye margin conspicuous, black and erect, but more prostrate on occiput, and pale and shorter on lower face. Frontovertex 0.4× head width, with ocelli arranged in a nearly right triangle. Eye inconspicuously microsetose with setae slightly shorter than an ommatidium. Toruli with upper margin in line with lower orbit. Scape in dorsal view strongly curved, in outer view 3.3× as long as wide, with a narrow ventral lamina in apical 3/4, and ventral margin evenly curved, otherwise nearly parallel sided; in outer view pedicel 1.7× as long as wide, F1 slightly transverse to quadrate; F2 nearly 2× as long as wide and following segments gradually shortened and broadened toward clava but all longer than wide (F8 only slightly); clava about as long as combined length of apical three funiculars; pedicel plus flagellum 1.5× HW. Relative measurements: HW 32–36, FV 12–14, HL 16–19, HH 27–33, EL 16–19, EW 13–15, MS 10–13, LOL 3–3.5, OOL 2–2.5, POL 4.5–6, MPOD 3, SL 16.5–20, SW 5–6.
Pronotum and mesoscutum shiny; pronotum medially divided, with fine alutaceous sculpture especially on lateral surfaces, and with a line of about 10 black, erect setae along posterior margin and less conspicuous setae scattered over dorsal surface; mesoscutum with convex median lobe and dorsal surfaces of lateral lobes finely imbricate-coriaceous (lateral lobe with very small mesh size), and rest nearly polished, lateral lobes carinate in posterior quarter to posterior half, with a row of 7 or 8 black, erect setae along mesal surface, and shorter, less conspicuous setae scattered over median lobe and on side of lateral lobe. Axillae finely obliquely alutaceous with narrow cells, appearing striate, with anterior edge in same plane as scutellum base, gradually convexly sloping posteriorly, each with 2–5 black erect setae dorsally; scutellum convex, dorsally semicircularly imbricatealutaceous, appearing strigose but more polished posteriorly, with a row of 2 or 3 black, erect setae on each side dorsally. Dorsellum polished, with a rounded median lobe covering apex of scutellum. Propodeum with plical depression broadly U-shaped, slightly wider than plical region, plical region narrow, with subparallel, carinate, anterior and posterior margins, and without median carina; callar region slightly convex with dense, long white setae in outer half, and with spiracle much smaller than a posterior ocellus and separated from anterior margin by a distance equal to its own smallest diameter. Acropleuron bare, alutaceous, with polished median area; cuticle very thin so that attachment site of mesotergal-mesopleural muscle clearly visible; mesepisternum alutaceous, with white setae except for extreme anterior region, the setae denser and longer in front of mid coxa and along acropleural sulcus. Hind coxa finely alutaceous, with dense white setae along ventral margin of outer surface and a few setae along dorsal edge. Mesotibia with 4 or 5 apical pegs. Fore wing 2.7× as long as wide; basal cell bare except setose basally and with 2–4 setae along mediocubital fold; costal cell microsetose basally on ventral side and with a single median line of longer setae; parastigma with longer, darker setae than rest of disc which is evenly setose, with setae darker and denser on infuscated areas and below marginal vein, paler in rest of wing, and those on clear spot in centre of disc translucent; venation with thick long uncus and enlarged stigma ( Fig. 32 View FIGURES 31 – 40 ), cc: mv: stv: pmv: uncus: u-pmv = 4.7–6: 6.6–7.7: 1: 1.7–2: 0.5: 0.2–0.5. Relative measurements: MSL 60–79, MSCL 28–32, MSCW 26–30, SCL 14.5–17, SCW 11–13, AXW 7–9, AXL 8–10, FWL 81–94, FWW 30–35, cc 24–26, mv 32–36.5, stv 4–5.5, pmv 8–9.5, uncus 2–3, u-pmv 1–2, HWL 72–85, HWW 15–20, MT 37–43, HT 32–39.
Metasoma with terga finely coriaceous to alutaceous, sparsely setose on sides; Mt2 and Mt3 strongly emarginate medially, the rest of tergites with straight posterior margins; Mt8 (syntergum) structure uncertain because gaster collapsed or distorted in all available specimens, but apparently Mt7 covering Mt8 (syntergum) up to emargination surrounding posteriorly facing anal sclerite. Ovipositor sheath 0.7× as long as hind tibia. Relative measurements: MTL ~50–57, MTW ~28–29, OL 23–26.
RECOGNITION. Females of Reikosiella bolivari most closely resemble that of R. graeca , both in color and antennal structure. Females of the two species are readily differentiated by setal pattern of the scutellum, which has at most 6 setae arranged in two parallel rows in R. bolivari and numerous setae arranged in a ribcage-like pattern in R. graeca . Also, the fore wing infuscation is more uniform in R. graeca , with dark bands reduced to spots, the basal cell is entirely and densely microsetose, and the stigmal vein has a very long uncus and strongly enlarged stigma.

DISTRIBUTION. Algeria (Kalina 1988); newly reported here for Spain and South France.
TAXONOMIC COMMENTS. Kalina (1988) described Eupelmus bolivari from a single female from Algeria and compared it with E. rostratus (= Reikosiella rostrata ). I have not seen the holotype, but the original description along with the accompanying photographs and drawings in Kalina (1988) are sufficient to place the species in Reikosiella (Hirticauda) . I am quite confident that the specimens listed above belong to this species, or at least to an undescribed species closely related to R. bolivari . It is possible that the specimens mentioned from Madrid under Eupelmus rostratus by Askew and Nieves-Aldrey (2004) also belong here.
