Micropterigidae

Sabatinca incongruella, copyright George W. Gibbs.

Belongs within: Lepidoptera.

The Micropterigidae are a cosmopolitan group of mandibulate moths characterised by the presence of multibranched sensilla on the antennal flagella. Larvae feed on ground-level vegetation such as liverworts or the lower leaves of grasses and other herbaceous plants (Nielsen & Common 1991).

Characters (from Nielsen & Common 1991): Small; head with raised hair-scales; ocelli present; chaetosemata absent; antennae moniliform, submoniliform or filiform, flagellar segments with multibranched sensilla (‘ascoids’); labrum centrally unsclerotised; epipharynx with asymmetrical armature; maxillary palps five-segmented; labial palps short, two- or three-segmented; fore tibial epiphysis present or absent; tibial spurs 0-0-4; fore wing with small jugum, humeral vein vestigial, Sc forked, Sc2-R1 cross-vein sometimes present, chorda present, R1 sometimes forked, cross-veins CuA-CuP and CuP-2A often present; hind wing as fore wing or with Sc2 fused with R1, A often simple; abdomen with or without S5 gland; male S8 more or less unsclerotised; ovipositor lobes retractile, non-piercing, segments 8 and 9 without apophyses. Eggs with specialised chorion structure. Larva slug-like, prognathous, with five or six stemmata; antenna three-segmented; without adfrontal ridges and ecdysial lines; salivary orifice not on spinneret; body hexagonal in cross-section; chaetotaxy reduced, with hair-like to claviform setae; thoracic legs three- or four-segmented, with apical claw; nonmuscular prolegs devoid of crochets often on first eight abdominal segments; some species with plastron. Pupa with pointed mandibles, used for opening the cocoon, and free appendages.
