Cheumatopsyche sp. B (light form larva)

(Figs 14–16)

Material examined. 4 larvae, Soldiers Creek, lower reaches, 23–24.xi.1996, A. Wells; 10 larvae, various stages, early pupa, Erskine Creek, 27.xii.2001, A. Wells; numerous larvae, various stages, Erskine Creek, 22.xii.2007; numerous larvae, various stages, Rocky Run, 24.xii.2007, A. Wells; prepupa, Soldiers Creek, 27.xii.2007, A. Wells.

Sclerotised body parts pale fuscous with darker band around posterior and lateral margins of thoracic nota; dorsum of head with scattering of brush-like secondary setae near apical margin of frontoclypeus. Frontoclypeus length: width ratio 1.41: 1.60; anterior margin crenulate, with 28–30 lobes; primary seta 17 short, almost indistinguishable from secondary setae; primary seta 22 near antero-lateral margin of pronotum slender, short about 1/3 length of pronotal suture. Posterior prosternites stout, contiguous with other sclerites. Gills present on abdominal segments I to VII.

Remarks. These paler larvae are distinguished clearly from the other larvae on Lord Howe Island by their pale colour, and also by the greater number of crenulations on the anterior margin and sparser arrangement of secondary setae on the frontoclypeus.
