Remyranina Schweitzer & Feldmann 2010, n. gen.
No full textGenus Remyranina n. gen. TYPE SPECIES. — Raninella ornata Remy, 1960. ETYMOLOGY. — Th e generic name combines the name of the author of the type species and prominent French paleontologist, Jean-Marcel Remy, and Ranina, the type genus of the family. OCCURRENCE. — Th e sole specimen was collected from probable Eocene rocks of Ivory Coast, Africa. DIAGNOSIS. — Small raninid with expanded, moderately broad fronto-orbital margin; ovoid, slightly longer than wide, with carapace ornamentation granular in anterior half and strongly terraced in posterior half. DESCRIPTION. — As for emended description of species. DISCUSSION Although the specimen referred to the new genus clearly allies it with the Ranininae, the combination of characters is unique and readily justifies creation of the new taxon. Th e genus to which it is most closely allied is Lophoranina Fabiani, 1910. Th ese two genera are the only ones in the Raninidae that are characterized by possession of a trifid rostrum and development of terraced ornamentation. However, Lophoranina tends to be widest near the front or at the level of the last anterolateral spine, whereas Remyranina n. gen. is broadest at the midlength, well posterior to the anterolateral spines. Furthermore, the anterolateral spines and the postorbital spines on Lophoranina are generally small, whereas those on Remyranina n. gen. are large. Finally, the terraced lines of Lophoranina extend nearly to the front of the carapace, well in advance of the branchiocardiac grooves, whereas those on Remyranina n. gen. are confined to the posterior half of the carapace. Th ere seems to be no other genus of raninids with which Remyranina n. gen. could be confused.Published as part of Schweitzer, Carrie E. & Feldmann, Rodney M., 2010, New fossil decapod crustaceans from the Remy Collection, Muséum national d'Histoire naturelle, Paris, pp. 399-415 in Geodiversitas 32 (3) on page 401, DOI: 10.5252/g2010n3a3, http://zenodo.org/record/468845

No full textDomene sagittata nov.sp. (Figs 27-34, Map 1) Type material Holotype: " VIETNAM Lao Cai, ca 40 km SE Sapa, 1400 m, 15- 16.II.05, G. de Rougemont leg. / Holotypus Domene sagittata sp.n., det. V. Assing 2013" (cRou). Etymology: The specific epithet is an adjective derived from the Latin noun sagitta (arrow) and refers to the shape of the ventral process of the aedeagus (ventral view), which somewhat resembles an arrowhead. Description: Body length 10.5 mm; length of forebody 6.0 mm. Habitus as in Fig. 27. Coloration: body black; legs blackish, with slightly paler tarsi; antennae blackish-brown. Head (Fig. 28) approximately as long as broad, widest across eyes, and convexly tapering behind eyes in dorsal view; frons somewhat domed and glossy in the middle; punctation (Fig. 29) relatively fine, weakly umbilicate, and very dense, interstices forming narrow ridges. Antenna 3.9 mm long; antennomere X nearly twice as long as broad. Pronotum (Fig. 28) 1.23 times as long as broad and approximately 0.9 times as broad as head, widest at anterior angles and distinctly tapering posteriad; lateral margins nearly straight in the middle in dorsal view; punctation similar to that of head; midline with rudiment of a fine glossy line. Elytra (Fig. 28) long, approximately as long as pronotum, each elytron with irregular longitudinal, narrowly elevated ridges; suture elevated in posterior three fourths; macropunctation (Fig. 30) moderately coarse and partly somewhat seriate; interstices with irregular micropunctation, otherwise not microsculptured. Hind wings probably present. Protarsomeres I-IV rather weakly dilated. Abdomen distinctly narrower than elytra; anterior impressions of tergites III-VI not very coarsely sculptured; punctation extremely fine and extremely dense on tergites III-VIII; interstices with distinct microreticulation; posterior margin of tergite VII with palisade fringe; tergite VIII with convex posterior margin. : sternite VII (Fig. 31) with weakly modified pubescence, in postero-median portion with some darker setae; sternite VIII (Fig. 32) with shallow median impression with unmodified pubescence and with rather shallow posterior excision, on either side of posterior excision with cluster of short dark setae; aedeagus (Figs 33-34) approximately 1.15 mm long; ventral process slender and weakly curved in lateral view, and somewhat shaped like an arrowhead in ventral view; dorsal plate lamellate and moderately sclerotized, with long apical and practically obsolete basal portion. : unknown Comparative notes: The similar chaetotaxy of the male sternite VIII and the slender ventral process of the aedeagus suggest that D. sagittata is closely related to the lineage D. immarginata + (D. scabripennis + D. alesiana). It is readily distinguished from these species by the finer punctation of the head and the pronotum, the different shape of the frons, the much longer elytra, the shallower posterior excision of the male sternite VIII, and by the different shape of the ventral process of the aedeagus. Distribution and natural history: The type locality is situated in North Vietnam (Map 1), not far from the border with Yunnan, to the southeast of Sapa [= Sa Pa]. The holotype was collected at an altitude of 1400 m.Published as part of Assing, V. & Feldmann, B., 2014, On Domene scabripennis ROUGEMONT and its close relatives (Coleoptera: Staphylinidae: Paederinae), pp. 499-514 in Linzer biologische Beiträge 46 (1) on pages 509-510, DOI: 10.5281/zenodo.530525

Strongly Connected Steiner Subgraphs with small number of Steiner vertices
No full textTitle: Strongly Connected Steiner Subgraphs with Small Number of Steiner Vertices Author: Tamás Dávid Kemény Department: Department of Applied Mathematics Supervisor: Dr. Andreas Emil Feldmann, Department of Applied Mathematics Abstract: Two well-established methods of dealing with hard optimization problems have been to develop approximation and parameterized algorithms. Recent results have shown that for some problems, it is only by combining these two approaches, into so-called pa- rameterized approximation algorithms, that we are able to efficiently find solutions that are of reasonable quality. This is the viewpoint from which we study the problem known as the Strongly Connected Steiner Subgraph problem, where a set of terminal vertices of an edge-weighted directed graph needs to be strongly-connected in the cheapest way possible.
