Speidel et al. (1996) placed this
group in a clade that was defined by presence of an epaulette in the tympanal
membrane, distinguishing the group on the basis of lichen‑feeding larvae
bearing long primary setae. They referred to Stenoloba Staudinger (see
below) as a possible member needing further investigation, but Sugi (1970) had
already associated the genus with Cryphia Hübner, the type genus of the Cryphiinae, a synonym
of Bryophilinae (Fibiger & Lafontaine, 2005) on the very features mentioned
above. Sugi, referring to earlier work by Yamamoto, stated that the primary
setae on the thorax and abdomen are generally long, arising from well
sclerotised pinacula. Seta SD1 on the meso- and metathoracic segments is much
longer than SD2, a feature seen also on at least the metathorax of Cryphia
species. All prolegs are fully developed. Kononenko & Ronkay (2000, 2001)
and Ronkay (2001) also placed Stenoloba in the Bryophilinae.
