Desoria sp. A

Two specimens from grass and moss cushions in a melt-water stream close to snowfields at Comox Glacier (49o33'N, 125o21'W), Vancouver Island (A. Fjellberg, 26.VIII.1983) are almost identical to olympica with 6+6 ocelli, 4–5 frontoclypeal setae, bifurcate maxillary palp, open uniform setal cover with abd. 1–4 sensilla in prow, smooth long macrochaetae, ventral tube with 1–2 frontal setae and 5–6 lateral setae, retinaculum with 2 setae, manubrium with 10–12 ventral setae in median field and dens with 7 dorsal setae in proximal half; same shape of mucro and sensillary equipment of antennae as olympica . The differences are presence of 5+5 setae in the basomedian field of labium and increased number of macrosensilla on th. 2–abd. 5: 44/ 323454 in sp. A. These specimens may represent an undescribed new species but more specimens need to be examined.
