Iconella isolata

General description: 

Description. Promefur color: mostly yellow, dark brown area limited to anterior 0.2 or less, rarely dark brown on anterior half, yellow on posterior half. Meso- and meta- femur color: mostly dark brown but with proximal 0.1–0.2 × yellow to orange. Metatibia and metatarsus color: Metatibia mostly yellow, at most with very small and faint brown spot on posterior 0.1 × or less; metatarsus mostly yellow, except for brown area on posterior half of first tarsomerus. Tegula and humeral complex color: tegula and humeral complex fully yellow to yellowish-white. Pterostigma color: centrally transparent, with yellow-white margins. Fore wing veins color: most of veins transparent or at most yellowish-white, margins of same color than interior of vein. Body length (head to apex of metasoma): 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm or 2.9 mm. Fore wing length: 2.8 mm, 2.9 mm, 3.0 mm, 3.1 mm or 3.2 mm. Ocular-ocellar line/posterior ocellus diameter: 1.9 × or 2.0 ×. Interocellar distance/posterior ocellus diameter: 1.9 ×, 2.0 × or 2.1 ×. Antennal flagellomere 2 length/width: 2.2 ×, 2.3 × or 2.5 ×. Antennal flagellomere 14 length/width: 1.3 × or 1.4 ×. Length of flagellomere 2/length of flagellomere 14: 2.3 ×, 2.4 × or 2.5 ×. Metafemur length/width: 3.2 × or 3.3 ×. Mesoscutellar disc: mostly smooth with few, scattered punctures near margins. Number of pits in scutoscutellar sulcus: usually 12 or less, ocasionally reaching up to 14 pits. Propodeum background sculpture: anterior 0.2–0.4 × with fine puntures; posterior 0.6–0.8 × mostly smooth, at most with some small carinae (mostly radiating from strong, longitudinal median carina). Mediotergite 1 width at anterior margin/width at posterior margin: 2.1 ×, 2.6 × or 2.8 ×. Mediotergite 2 width at posterior margin/length: 3.6 ×, 3.7 ×, 3.8 ×, 4.5 × or 4.6 ×. Ovipositor sheaths length/metatibial length: 1.0 ×.

Male. As female.

Iconella isolata had been considered to be a subspecies of Iconella etiellae. After study of numerous specimens, Fernández-Triana et al. (2013) found consistent and significant differences in morphology, hosts and geographical distribution and thus considered Iconella isolata as a different species on its own.
