Name
Zambion eileenae sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnosis
Zambion eileenae can be distinguished from all other Zambion spp. by having all legs completely dark (brown or black), without any orange or yellow (Fig. 7). All other species have some orange or yellow in some parts of the legs.
Description
Adult. Female. Fore wing length 6.0 mm. Clypeus separated from supraclypeal area by a strong groove (Fig. 13). Malar space 0.7 times basal width of mandible. Supraclypeal area 1.9 times as high as wide (Fig. 13), dorsomedially without a short, narrow, longitudinal lamella between the antenna. Supra-antennal horn short and triangular in dorsal view (Fig. 19), 0.3 times as long as width of pedicel at midheight in lateral view (Fig. 26). Ocello-ocular distance 1.8 times ocellar diameter. Gena 0.8 times transverse diameter of the eye. Flagellum with 29 segments on left, 28 on right.
Notaulus absent. Epicnemial carina mostly straight medially, not curving away from anterior edge of mesopleuron near ventral corner of pronotum (similar to Zambion rogeri shown in Fig. 32). Scutellum with lateral carinae extending 0.5 length of scutellum. Medial longitudinal carinae of propodeum complete and strong anterior to posterior transverse carina (as in Zambion hirtum shown in Fig. 34). Carina running from pleural carina to propodeal spiracle complete. Posterior transverse carina of propodeum with lateral abscissa roughly straight, point of union with pleural carina at about 0.4 distance from posterior end of pleural carina to propodeal spiracle (similar to Zambion monodon shown in Fig. 36). Ventral transverse carina extending from metasomal foramen to pleural carina present (as in Fig. 35). Fore tibia without an apical point on dorsal surface. Hind femur 3.6 times as long as medial width. Hind tarsal claw pectinate to about 0.5 times length of claw. Angulation of fore wing vein 2m-cu weak.
Tergite 1 of metasoma 1.8 times as long as apical width. Dorsal longitudinal carinae of T1 extending to 0.7 length of T1, dorsolateral longitudinal carinae extending beyond spiracles up to 0.7 length of segment.
Black. Legs, metasomal sternites and ovipositor sheaths at base brown, the legs lightening from base to apex except hind leg with tibia and tarsus darker brown. Flagellomere 1 at extreme base and flagellomeres 2+ on ventral surface yellow brown, gradually lightening towards apex, dorsal surface of flagellum brown, lightening to yellow brown apical to middle. Apical 0.3 of clypeus orange-brown. Membrane of fore wing strongly infumate (Fig. 7), slightly less imfumate basally. Body covered with dense silver setae.
Male: unknown.
Material examined
Holotype: ♀, Label 1: UGANDA, Ruwenzori Range [Rwenzori Mountains], xii.1934-i.1935., B.M. E. Afr. Exp. B.M. 1935-203. Label 2: Namwamba Valley, 6,500 ft., F.W. Edwards. [NHM]. Condition: intact.
Etymology
This species, collected in the “Mountains of the Moon”, is named in honour of the senior author’s mother, Mrs. Eileen Bennett, for her support and understanding, especially when finding dead caterpillars and grasshoppers in jars or worse (live ones wandering through the house).
