Drymeia fratercula sp. nov. Figs 10–18 Diagnosis. This species is close to the Alpine Drymeia glacialis (Rondani, 1866), e.g. 3 postsutural dorsocentrals, very broad parafacial, and conspicuous facial snout. However, D. glacialis is a larger, more robust species with longer and stronger setae, and the male has the frontal width equal to diameter of anterior ocellus; hind femur with no or few posteroventrals in apical half; fore tarsus with tarsomere 1 produced posteroventrally at tip into a conspicuous thorn, and tarsomere 1 almost as long as the length of tarsomeres 2–5 combined. Etymology. The specific name “ fratercula ” is Latin and means “little brother”. This reflects the close similarity between this species and D. glacialis (Rondani). Type-material Examined.

Fronto-orbital plate silvery-white pruinose below, dull above; parafacial silvery-white pruinose; face grey, and gena light grey pruinose; most of occiput subshining. Frons at narrowest point separated by a distance equal to 2–3 times diameter of anterior ocellus, the margins of each fronto-orbital plate touching or narrowly separated on upper half of frons where the frontal vitta may be obsolete. Ocellar setae long. 12 pairs of frontal setae, ...
