No full textStegana (Steganina) montana sp. nov. (Figs 21–27) Diagnosis. This species is related to S. dianensis sp. nov., but clearly distinguishable from the latter by the scutellum and tenth sternite, in this species: scutellum yellow medially, black laterally; tenth sternite expanded distally (Fig. 23). Description. Male terminalia: Epandrium broadened on posterior margins, wider than 3 / 5 high, pointedly protruded ventrally (Fig. 21). Cercus lacking pubescence (Fig. 21). Surstylus with 6 prensisetae submedially (Fig. 22). Tenth sternite furcated basally (Fig. 23). Paramere with ca. 3 sensilla (Figs 24, 25). Aedeagal opening slightly infundibular in ventral view (Figs 24, 25). Gonopods acute apically, with broadened, medially depressed projection dorsomedially (Fig. 27). Measurements.

VARIATIONAL-PROBLEMS WITH OBSTACLES AND HARMONIC MAPS
No full textLet (M, g) be an oriented Riemannian manifold of finite dimension and let C be a closed subset of the Euclidean space R k. In this paper we illustrate some results on harmonic maps u: M →C which were obtained in collaboration with Chen Yun-Mei. Our first purpose was to find a generalization of the usual definition of a harmonic map between two Riemannian manifolds in order to consider less regular target spaces. Our second aim was to extend a result by Chen and Struwe about the heat flow of harmonic mappings into manifolds with boundary
