Haasea musimontia ( Strasser, 1937) —see below

Diagnosis. H. musimontium differs from congeners by some gonopodal structures, viz., 1) simple, rounded posterior lamella not bent down in an extensions (vs. bilobed posterior lamella in H. faucium , H. filicis , H. inflata and H. gru- beri sp. nov.; posterior lamella with distal notch in H. flavescens and H. hungarica ; posterior lamella ear-shaped and bent down in an extensions in H. fonticulorum and H. germanica ), 2) several teeth on posterodistal margin of mesal process (vs. mesal process knife-like with posterobasal tooth in H. vidinensis or posterodistal margin of mesal process with one strong tooth in H. germanica ) 3) absence of anterior lateral process (vs. developed in H. cyanopida , H. lacusnigri , H. intermedia , H. microcorna , H. makarovi sp. nov., and H. plasana ).

Etymology. Strasser (1937) named this species after the type locality Monte Musi (môns =mountain). Since (musi)montium is a Latin genitive plural, the species name should remain musimontium although Haasea is feminine gender.

Type material examined: Lectotype ♂ ( MHNG), here designated, body in two parts, mounted on cardboard; two microslides: 1) Orobainosoma musimontium Stra. 22.10.1934. Musi. Torretal. Friaul. 1040 m., anterior and posterior gonopods, 2) Orobainosoma musimontium Stra. 22.10.1934. Musi. Torretal. Friaul. 1040 m., leg-pairs 6, 7, 10 & 11. Paralectotypes ( MHNG): 1 ♀, alcohol material, Orobainosoma musimontium Strass. , det. K. Strasser, Italie (Udine): Vallée Torr. Torre, (Musi, Vedronza, Tarcento), 250–1200 m; 1 ♀, mounted on cardboard together with lectotype.

Distribution ( Figs 38 , 41 ). Italy: known only from its type locality, Monte Musi in Triveneto, near Lusevera, Udine ( Strasser 1937).

Comment. Only one male and two females of this species are known.
