( Figs. 1, 3 View FIGURES 1 – 4 , 5 View FIGURES 5 – 6 , 7 View FIGURES 7 – 9 , 8.)

Etymology. The specific epithet ‘pyrenaea’ alludes to the type area, the Pyrenees range of mountains.

Description. Drymeia pyrenaea sp. nov. agrees in most respects so closely with D. brumalis (Rondani) that the differences between the two species are conveniently presented in table format, see Table 1 View TABLE 1 .

Type material examined. All deposited in ZMUC: SPAIN: GERONA: Queralps [Caralps]: 1200–1300m, holotype male, paratypes 1 male, 1 female, 13–16.vi.1982 (Andersen, Lyneborg & Michelsen); LÉRIDA: Sorpe, 1200–1300m, paratypes 3 males, 2 females, 19–22.vi.1982 (Andersen, Lyneborg & Michelsen).

Additional material examined. All deposited in ZMUC: GERONA: S a Nuria, 2100m, 2 females, 10.vii.1984 (V. Michelsen); Bruguera SE Ribes, 1700m, 1 male, 1 female, 18.vi.2002 (V. Michelsen). LÉRIDA: Sorpe, 1200– 1300m, 3 females, 19–22.vi.1982 (Andersen, Lyneborg & Michelsen); Valle de Arán, Arties, 1200–1800m, 1 male, 20.vi.1982 (Andersen, Lyneborg & Michelsen), 1800m, 1 female, 6-7.vii.1984 (V. Michelsen); Gavàs 6km NE Esterri d’Aneu, 3 females, 13.vi.2002 (V. Michelsen). TERUEL: Cantavieja, 1200m, 1 female, 28.vi.1984 (V. Michelsen). PORTUGAL: Braga, S a do Gerez, 1 female, 10.vii.1990 (V. Michelsen).

Examined Iberian material of Drymeia brumalis is as follows: SPAIN: HUESCA: 15km NE Benasque, 1 male, 2 females, 7.vii.1997 (V. Michelsen).

Distribution. Drymeia pyrenaea sp. nov. is so far only known from northern, elevated parts of the Iberian Peninsula, but the coexistence of D. brumalis in that area suggests that D. pyrenaea might even occur in the Alps.

TABLE 1. Differences between males and females of Drymeia pyrenaea sp. nov. and D. brumalis (Rondani).

Sex	Character	D. pyrenaea sp. nov.	D. brumalis (Rondani)
Male	1. Abdomen in posterior views	revealing some brownish grey dust- ing on tergite(s) (IV–)V demarcating a broad dark median vitta	shiny brownish black through uniform dark brown dusting
Male	2. Longest aristal pubescence	decidedly longer than greatest aristal diameter (Fig. 1)	about same length as greatest aristal diameter (Fig. 2)
Male	3. Shortest distance between eyes	exceeding distance between inner margins of posterior ocelli	shorter than distance between inner margins of posterior ocelli
Male	4. Mid femur on v-surface	practically bare between av- and pv- setal rows	with hair-like setae abundant between av- and pv-setal rows
Male	5. Hind tibial av- and pv-setae	all short, but only pv-setae fine and hair-like	all long, fine and hair-like
Male	6. Apical extension of hind tibia	practically absent; apical av-seta well retained (Fig. 3)	short but distinct; apical av-seta fine, inserted on tibial extension (Fig. 4)
Male	7. Cercal plate apically	strongly concave with a shallow median notch (Fig. 5)	truncated with a deep median notch (Fig. 6)
Female	8. Parafacial	at level of antennal base with a shiny patch devoid of dusting	wholly covered in silvery grey dusting
Female	9. Longest aristal pubescence	decidedly longer than greatest aristal diameter	about same length as greatest aristal diameter
Female	10. Apical v- and pv-setae of hind tibia	clearly shorter than apical av-seta	about same length as apical av-seta
Female	11. Anterior sclerite of tergite VIII	more or less membranized on middle part (Figs. 7, 8)	fully sclerotized (Fig. 9)
