Deler-Hernández, Fikáček & Seidel (PR2a) (2 larvae associated with adults: NMPC; DNA extraction of one larva: MF1731.L)

Larval diagnosis.

Head capsule (Fig. 14k) ca. as long as wide; cuticle smooth, without distinct miscrosculpture; head capsule with two “lenses” (anteriorly and posterior of the eye spot) on each side, lateral part of head capsule with apparent group of setae (PA12-14 sensu Fikáček et al. 2008) ca. at midlength; clypeolabrum angulate at the right side from the setiferous emargination. Metanotum (Fig. 14g) with very narrow and weakly sclerotized transverse tergite. Legs (Fig. 14g) reduced into one-segmented setiferous tubercle. Membranous parts of thorax and abdomen covered by extremely short and dense whitish microtrichia. Abdominal segments (Fig. 14 g–i) without lateral lobes, smooth (i.e. without transverse rows of tubercles) dorsally. Tergite on 8th abdominal segment (Fig. 14l) wider than long, shallowly sinuate on anterior margin, weakly sinuate on posterior margin.
