♂, NMNH (examined).

Specimens examined.

3 ♀, 3 ♂ (CNC) United States: CA (Apple Valley, Helendale, Kramer Hills and Panamint Valley) and UT (Dugway Proving Ground). Collecting dates of specimens examined: May and June (1953-1961).

Description.

Promefur color: almost completely dark brown (yellow area absent or limited to posterior 0.2 x) (Fig. 17). Meso- and meta- femur color: mostly dark brown but with proximal 0.1-0.2 × yellow to orange (Fig. 19). 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 (Fig. 19). Tegula and humeral complex color: tegula and anterior half of humeral complex yellow to yellowish-white, posterior half of humeral complex light brown to dark brown. Pterostigma color: mostly brown, with yellowish-white spot at anterior 0.2 × (Fig. 18). 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): 3.0 mm or 3.1 mm. Fore wing length: 3.3 mm or 3.4 mm. Ocular-ocellar line/posterior ocellus diameter: 1.6 × or 1.7 ×. Interocellar distance/posterior ocellus diameter: 2.4 × or 2.6 × (Fig. 20). Antennal flagellomere 2 length/width: 2.6 × or 2.7 ×. Antennal flagellomere 14 length/width: 1.4 × or 1.7 ×. Length of flagellomere 2/length of flagellomere 14: 2.2 ×. Metafemur length/width: 3.2 × or 3.3 ×. Mesoscutellar disc: mostly smooth with few, scattered punctures near margins (Fig. 22). Number of pits in scutoscutellar sulcus: usually 14 or more, ocasionally reaching up to 16 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) (Fig. 21). Mediotergite 1 width at anterior margin/width at posterior margin: 2.4 × or 2.5 ×. Mediotergite 2 width at posterior margin/length: 5.0 × or 5.1 × (Fig. 22). Ovipositor sheaths length/metatibial length: 1.1 × (Fig. 19).

Molecular data.

We analyzed one 607 bp barcode for this species.

Biology/ecology.

Hosts: Etiella zinckenella , Olycella junctolineella , Psorosina hammondi , and Ufa rubedinella ( Pyralidae ).

Distribution.

United States: AR, AZ, CA, CO, IA, NM, OK, WA.

Comments.

There is a record from Virginia, United States ( Yu et al. 2012). While we have not been able to examine that specimen, based in the known distribution of New World species of Iconella and their hosts, it is very likely that the VA specimen actually belongs to Iconella canadensis Fernández-Triana.
