Diagnosis. Differs from congeners, except H. intermedia , H. makarovi sp. nov., H. microcorna and H. plasana , by the presence of a strongly developed anterior lateral process on angiocoxites. From the four above mentioned species H. lacusnigri differs by the presence of laid, sabre-like anterior lateral process with posterior half strongly bend distad (vs. erected and straight in H. intermedia , H. makarovi sp. nov., H. microcorna and H. plasana ). Further, H. lacusnigri differs from H. intermedia , H. microcorna and H. plasana by the presecne of vestigial posterior lamella (vs. well-developed in H. intermedia , H. microcorna and H. plasana ) or by the absence of teeth on mesal process (vs. presence in H. makarovi sp. nov.).

Distribution ( Figs 38 , 42 ). Montenegro: Crno Jezero Lake, Mt. Durmitor ( Gulička 1968; Mršić 1990), near Ledena pećina Cave, Obla Glava, Mt. Durmitor ( Gulička 1968), Sušica canyon, Mt. Durmitor ( Mršić 1990), Tepca, Mt. Durmitor ( Mršić 1990).

Type locality. Mt. Durmitor , Montenegro .

Comments. Both Strasser (1971) and Mršić (1985) stated that Gulička (1968: 4, fig. 6) incorrectly drew an ad- ditional process [additional “Keratit” according to Strasser (1971) or additional “Pugio” according to Mršić (1985)] of the anterior gonopods. Later, Makarov (2008) stated that Gulička’s (1968: 4, fig. 6) drawing is correct, and we agree. But Makarov’s (2008: 94) hypothesis on the elovution of “Pugio” is incorrect, since “additional process” in Gulička’s drawing is nothing but the posterior lateral process (sometimes labeled as “Pugio”, sometimes as “Cor- nicle”), that exists in all Haasea species.

Although Gulička’s (1968: 4, fig. 6) drawing is quite schematized, we find it completely correct. The angiocox- ite has three well-developed processes viz., mesal and posterior lateral process of almost same size (mesal one is somewhat larger compared to posterior lateral one) and shape, both elongated, blunt and strongly curved posteriad, while anterior lateral process is robust, laid, with distal half strongly bent distad. The posterior lamella is vestigial.
