Description.
Promefur
color: dark brown on anterior half, yellow on posterior half. Meso- and meta- femur color: fully dark brown to black (Fig. 4). Metatibia and metatarsus color: Metatibia with brown to black coloration on posterior 0.2-0.4

Tegula and humeral complex color: tegula and humeral complex fully yellow to yellowish-white (Fig. 9). Pterostigma color: centrally yellow-white, with thin brown margins (Fig. 5). Fore wing veins color: at least some veins with thin brown margins and interior of veins yellow to light brown. Body length (head to apex of metasoma): 2.7 mm or 2.8 mm. Fore wing length: 3.0 mm. Ocular-ocellar line/posterior ocellus diameter: 2.2

Molecular data.
We analyzed three full 658 bp barcodes for this species.
Biology/ecology.
Host: An undescribed species of
Phycitinae
(
Pyralidae
) with provisional name "phyjanzen021 Janzen855" in the ACG database (http://janzen.sas.upenn.edu/caterpillars/database.lasso). Caterpillar collected while feeding on the foliage of
Lepidoploa salzmannii
(
Asteraceae
).
Distribution.
Only known from the holotype locality, in Sector Rincon Rain Forest of ACG at 410 m.
Comments.
The species has been reared only in one place from three caterpillars collected at the same time on the same species of food plant, out of 12,000+ rearings of ACG
Pyralidae
of more than 200 species. A single additional specimen, identified by DNA barcoding, has been reared in 2012 from the same species of host caterpillar in the same place and on the same food plant, but was not available for study.
Iconella andydeansi
is sympatric with
Iconella jayjayrodriguezae
in ACG, the latter being a species with a slightly larger ACG rain forest distribution but equally narrow food plant record, and also known from Chiapas, Mexico. Those are the only two species of New World
Iconella
that are known to be sympatric, and that was revealed through extensive collecting in ACG and the use of DNA barcodes. It is likely that further collecting in other areas of the Neotropics, as well as the barcoding of more fresh specimens, will reveal additional species.
Etymology.
This species is named in honor of Andy R. Deans (Pennsylvania State University, United States) in recognition of his major contribution to the taxonomy of the many species in the microgatrine genus
Alphomelon
that occur in Area de
Conservacion
Guanacaste (e.g.,
Deans et al. 2003
).
