Pterostigma 3.4 × as long as wide, vein r arising near middle of pterostigma, subequal to pterostigma width and 0.85 × as long as 3-SR. Lengths of veins 2-SR: 3-SR: r-m =3.5: 4.77: 2.96; lengths of veins 2-SR+M: 2-M: m-cu = 3.6: 7.0: 4.45; lengths of veins 2-CU1: 1-CU1 7.3: 4.1, 2-CU1 1.8 × as long as 1-CU1; 2-SR 0.73 × as long as 3-SR; SR1 2.8 × as long as 3-SR. Hind wing (relative measurements): lengths of veins 1-rm: SC+R1 = 6.94: 1.72; veins 2+SC+R not distinct; vein SR reduced distally, 2m-cu directed towards wing base; marginal cell, basal cell and base of wing evenly setose; marginal cell of hind wing not strongly expanded at basal quarter. Length of fore femur: tibia: tarsus = 0.83: 1.4: 0.9; fore femur 1.9 × longer than maximally deep; fore tibia with mid-longitudinal ridge. Hind femur 3.0 × longer than maximally deep; lengths of hind femur: tibia: basitarsus = 1.3: 1.6: 0.54; hind basitarsus 2.1 × longer than maximally deep. Metasomal tergites moderately setose; first metasomal tergite coarsely longitudinally striate with mid longitudinal carina terminating before apical margin (Fig. 7F), 1.2 × longer than wide, anteriorly with smooth triangle formed by uniting dorsal carinae in anterior one-third; second metasomal tergite largely punctate, coarse and sparse striations in anterior one-third, 2.8 × wider than medially long, with triangle anteriorly followed by median ridge; second suture distinct, little convex; third metasomal tergite 3.8 × wider than long, punctate (Fig. 8B); metasomal tergites 4–7 with sparse punctations. Colour: Body largely yellowish brown; antenna yellowish brown (scape with dark brown edges); eyes black; mandibular tip, inter-ocellar region, prescutellar furrow and axilla dark brownish-black; brown infuscation near occiput; mesoscutum anterio-medially, anterio-laterally and posterio-laterally yellowish brown, rest dark brown (in ‘H’ shaped impression); mesopleuron dark brown above posterior region; propodeum yellowish brown; wings infuscate; fourth tergite with black coloration in anterior two-third regions; six and seven tergites with dark brown band. Comments. Yelicones elaeodendronicus sp. nov. comes nearest to Y. koreanus Papp, 1985 in having similar round shaped and non-constricted temple and first tergite about as long as wide however differs in having OOL 4.73 × POL (vs 1.9–2 × in Y. koreanus); tentorial pits 2.8 × as far from each other as to nearest point of eye (vs 2 × in Y. koreanus); r 0.85 × 3-SR (vs equal); SR1 distinctly bent before reaching apex (vs curved in Y. koreanus); second tergite anterior one third with coarse striations, posterior two-third and following tergites punctate (vs anterior two-third with finer though denser striations than of first tergite, remaining T2 and T2 onwards polished in Y. koreanus). Yelicones elaeodendronicus sp. nov. can be separated from Y. belokobylskiji Quicke, Chishti and Chen, 1997 in having face mostly deeply transverse rugose striate (vs punctations of face not merging into transverse striations in Y. belokobylskiji); pterostigma uniformly pale yellow (vs distinctly bicolorous in Y. belokobylskiji); T2 with basal triangular area punctate (vs smooth in Y. belokobylskiji). Biology. Reared from a pyralid caterpillar (Lepidoptera: Pyralidae) (Fig. 9) feeding on the host plant Elaeodendron glaucum (Rottb.) Pers. Etymology. The species epithet ‘ elaeodendronicus ’ is derived from the host plant genus Elaeodendron on which the caterpillar was feeding before mummification.
