Omphale connectens Graham – Wikispecies link – Pensoft Profile
- Omphale connectens Graham, 1963:261. Holotype female in OUMNH, examined.

Type material. Holotype female, type no. 1297 in OUMNH. Additional material. 188♀ 11♂: Czech Republic 2♀ (BMNH), Denmark 16♀ (LUZM), France 2♀ (RMNH), Germany 3♀ (RMNH), Hungary 14♀ (BMNH, CH), Netherlands 4♀ (RMNH), Russia 36♀ 4♂ (BMNH), Sweden 80♀ 3♂ (BMNH, CH, NHRS), United Kingdom 31♀ 4♂ (BMNH).
Diagnosis
Forewing with row of admarginal setae with all, or most, from ventral marginal vein and with radial cell bare (Fig. 283); face shiny with very weak sculpture and partly smooth, to completely smooth (Fig. 287); forecoxa black or dark brown metallic, mid- and hind coxae yellowish brown (Fig. 278); female flagellomeres 1–3 ventrally with two rows of setae, attached basally and subbasally (Fig. 286); postmarginal vein 1.5–2× as long as stigmal vein.
Description
Female. Length of body 1.0–2.4 mm. Antenna with scape yellowish brown with dorsal edge brown; pedicel and flagellum dark brown; pedicel + flagellum 2.4× as long as distance between eyes; first flagellomere 1.1× as long and 1.0× as wide as second (Fig. 286); flagellomeres with scattered short setae, flagellomeres 1–3 ventrally with two sets of setae, one set attached close to base and one attached subapically on the flagellomere; clava 2-segmented. Face purple metallic and golden green, to dark brown with metallic tinges (Fig. 281), with very weak sculpture and partly smooth, to completely smooth (Fig. 287); clypeus green metallic, to dark brown with metallic tinges, smooth, trapezoid to semicircular, 1.4× as wide as high; gena bronze to dark brown metallic; lower frons bronze, with engraved rather strong reticulation, smooth close to eyes, subtorular area smooth; interscrobal area smooth; antennal scrobes join on frontal suture; frontal suture V-shaped; upper frons golden green, smooth. Vertex bronze, with engraved reticulation inside ocellar triangle, smooth outside triangle (Fig. 288). Occipital margin rounded (Fig. 288).
Mesoscutum bluish green metallic with posterior ½ of midlobe bronze, to completely bronze, golden green or green metallic (Fig. 279), with engraved reticulation (Fig. 285), midlobe with two pairs of setae; notauli as indistinct impressions. Scutellum bronze (Fig. 279) with engraved reticulation (Fig. 285); 1.2× as long as wide, with anterior margin smoothly and weakly curved forwards. Axillae black metallic (Fig. 279). Dorsellum bronze (Fig. 279), smooth and slightly convex (Fig. 285), 0.3× as long as wide, and 0.6× as long as length of median propodeum. Entire lateral mesosoma bronze (Fig. 278); transepimeral sulcus strongly curved forwards. Propodeum golden with purple tinges (Fig. 279), smooth (Fig. 285); propodeal callus with two setae. Legs with forecoxa dark brown with golden tinges, mid- and hind coxae yellowish brown (Fig. 278); femora pale brown to dark brown; tibiae yellowish brown to pale brown; foretarsus pale brown, mid- and hind tarsi yellowish brown; midleg with first tarsomere 0.3× as long as length of tarsus. Forewing transparent, veins yellowish brown and setae dark brown (Fig. 283); speculum closed; admarginal setae 6–10, arising from marginal vein and from membrane just below vein; radial cell bare; postmarginal vein 1.5–2.0× as long as stigmal vein; stigmal vein slender. Hind wing transparent, apex pointed (Fig. 283). Forewing WIP (Fig. 284) with apical ½ magenta with blue margins and basal ½ yellow/blue (=green), these two areas separated by narrow bands in yellow and magenta.
Petiole yellowish brown. Gaster with first tergite golden green, remaining tergites golden; elongate and 1.6–2.0× as long as length of mesosoma; 7th tergite 0.1× as long as length of gaster.
Male. Length of body 1.1–1.4 mm. Features as in female except as follows. Antenna with scape expanded (Fig. 290), distinctly wider than in female, yellowish brown with dorsal and ventral edges dark brown, in some specimens entire inner surface green metallic; pedicel + flagellum 3.5× as long as distance between eyes; first flagellomere 1.1× as long as second flagellomere; flagellomeres with scattered setae; clava 1-segmented. Face bright bluish green metallic (Fig. 282), smooth (Fig. 291); clypeus bright bluish green metallic, trapezoid, 1.5× as wide as high; gena purple metallic; lower frons bright bluish green metallic, with engraved very weak reticulation, smooth close to eyes; interscrobal area bright green metallic; upper frons golden purple or bluish green metallic, with engraved very weak reticulation; vertex purple metallic, with engraved weak reticulation (Fig. 292).
Mesoscutum golden purple, golden red (Fig. 280), golden green or blue metallic, with engraved and weak to very weak reticulation (Fig. 289), midlobe sometimes smooth, midlobe with one pair of setae (posterior pair). Scutellum purple metallic (Fig. 280) or blue metallic, with engraved weak reticulation (Fig. 289); anteromedian margin straight. Axillae purple metallic (Fig. 280). Dorsellum golden (Fig. 280), 0.5× as long as wide. Entire lateral mesosoma black metallic to bronze. Propodeum golden purple or golden green (Fig. 280). Forewing infumate; admarginal setae 6–8, arising from ventral surface of marginal vein.
Petiole yellowish brown, as long as wide with anterior part narrowing off. Gaster black with golden and green metallic tinges, 1.0–1.1× as long as length of mesosoma. Phallobase and aedeagus as in Fig. 493.
Host
Unknown. The record for Geocrypta galii in Gijswijt (1976)[1] concerns Omphale incognita.
Distribution
Czech Republic (new record), Denmark (new record), France (Gijswijt 1976[1]), Germany (Gijswijt 1976[1]), Hungary (new record), Netherlands (Gijswijt 1976[1]), Russia (new record), Sweden (Hansson 1991[2]), United Kingdom (Graham 1963[3]) (Fig. 522).
Remarks
Graham (1963)[3] regarded Omphale connectens as similar to species in the aetius-group, but placed it outside the group as a single species because of different setation in the forewing and different sculpture on the head between lower margin of eye and mouth opening. However, the male genitalia, which are very distinctive for species-group aetius, clearly show that Omphale connectens belongs in the aetius-group.
