Neobarombiella grotefendi Bolz & Wagner 2012, sp. n.
No full textNeobarombiella grotefendi sp. n. (Figs 57, 157–160) Etymology. Named after Jens Grotefend, a long-time friend of Helmut Bolz. Total length. 3.35–3.80 mm (mean: 3.50 mm) (n=10). Head. Head, labial and maxillary palpi yellow. Antenna slender, entirely yellow in about 50% of material studied, rest brown from fourth to ninth antennomere (Fig. 157). Length of second to third antennomere 0.83–0.85 (mean: 0.84), and length of third to fourth antennomere 0.60–0.67 (mean: 0.63) (Fig. 159). Eyes small (Fig. 157), width of eye to interocular distance 0.47–0.50 (mean: 0.48). Thorax. Pronotum yellow; coarsely and deeply punctuated; trapezoidal, pronotal width 1.08–1.22 mm (mean: 1.14 mm), pronotal length 0.56–0.62 mm (mean: 0.58 mm), and pronotal length to width 0.49–0.52 (mean: 0.51). Elytron yellow, deeply and coarsely punctuated; elytral length 2.60–3.00 mm (mean: 2.74 mm), elytral width 1.70–2.10 mm (mean: 1.88 mm), and maximal width of both elytra to length of elytron 0.65–0.70 (mean: 0.68) (Fig. 157). Meso- and metathorax yellow, legs entirely yellow; length of basi-metatarsus to metatibia 0.38–0.39 (mean: 0.38). Abdomen. Yellow. Male genitalia. Median lobe very short, parallel-sided in ventral view, rounded apically with deep U-shaped incision; down-curved in lateral view and apically elongate, lacking sclerotized ridges or other characteristic structures; endophallic brush covered by tectum and median lobe, and lacking spiculae (Fig. 158). Diagnosis. Neobarombiella grotefendi sp. n. is characterised by the coarse punctuation of the pronotum and the elytra, its colouring, distribution range and peculiar median lobe. Neobarombiella budongoensis sp. n., which occurs syntopically, has narrow outer elytral and sutural margins and the median lobe differs in having sclerotized structures laterad of the apical V-shaped incision. The median lobe of Neobarombiella grotefendi sp. n. is very short and has no sclerotized structures (Figs 130, 158). Although N. frohnorum sp. n. is rather similar, it is generally bigger, total length, 4.35–4.85 mm (3.35–3.80 mm in N. grotefendi sp. n.) and has superficially punctuated elytron (Figs 149, 157).

Microfacies, Larger Benthic Foraminiferal Assemblages, and Age Determinations of Eocene and Oligocene Limestone Samples from the Fila de Cal and Térraba Formations, Southern Costa Rican Forearc – Data Reports
No full textThe dataset consists of six individual data files, including Data Summary and Methods, sampling location map, and four data reports written in 2017 and 2019 in collaboration with the Centro de Investigación en Ciencias Geológicas of the University of Costa Rica (CICG-UCR); ongoing research projects: (1) Strengthening research in Stratigraphy and Tectonics of southern Costa Rica (research grant UCR 830-B0-242) and (2) Cenozoic Calcareous Depositional System of the Fila de Cal Formation, Costa Rica (research grant UCR 830-B7-277) in charge of Percy Denyer, Teresita Aguilar, Aristides Alfaro, Valentin Chesnel, and Erick Rodríguez.
During these research projects, a total of 29 thin sections made of nineteen selected limestone rocks collected from the Fila de Cal and Térraba Formations have been prepared until yet for further laboratory sample analysis and age determination. The reports contain the limestone microfacies descriptions and detailed micropaleontological results, including sample age determinations based on their larger foraminiferal assemblages. The summary of the data reports contains in addition the research methods.
The selected limestone samples were collected during field research campaigns in the Fila Costeña thrust belt area of southern Costa Rica by the CICG researchers and later examined and dated by Angela Bolz and Claudio Calvo in Stuttgart, Germany where part of the studied materials (thin sections and high-resolution image copies) are actually stored. The original hard rock samples as well as the thin sections of sample series VC remain with the CICG collectors at the University of Costa Rica. Sampling localities and their precise coordinates are depicted on Google site map file of the dataset: Sampling site map.kmz, with location of sample series CH, Te, Co, and VC.
All laboratory sample analysis and data reports were carried out in scientific collaboration with the researchers at the Centro de Investigación en Ciencias Geológicas of the Universidad de Costa Rica mentioned above.
In sedimentological terms, the sampled limestone succession records a large and stable carbonate platform. The microfacies and limestone age determinations show that both shallow and deeper marine platform environments were concomitant in the Eocene as well as in the Oligocene. The Rupelian upper part of the carbonate succession and the few Henningsen (1966) limestone beds record the drowning carbonate platform episode in this area. This development has likely to do with the carbonate platform declining caused by the siliciclastic sedimentation of the Térraba Formation, which finished the carbonate domain of the Fila de Cal. The larger foraminifers determined in these limestone samples also reveal two successive assemblages. That means the carbonate factory of the Fila de Cal platform didn’t stop its sediment production in the late Eocene (Priabonian) to continue into the early Oligocene (Rupelian).

Neobarombiella frohnorum Bolz & Wagner 2012, sp. n.
No full textNeobarombiella frohnorum sp. n. (Figs 149–152) Etymology. Named after Anna-Maria and Norbert Frohn, Helmut Bolz’s grandparents. Total length. 4.35–4.85 mm (mean: 4.58 mm) (n=8). Head. Frons, vertex and labrum yellow, labial and maxillary palpi brownish-yellow. Antenna yellowishbrown, brown from fifth antennomere to apex (Fig. 149); length of second to third antennomere 0.59–0.67 (mean: 0.62), and length of third to fourth antennomere 0.63–0.69 (mean: 0.65) (Fig. 151). Eyes large and with short interocular distance (Fig. 149), width of eye to interocular distance 0.52–0.59 (mean: 0.55). Thorax. Pronotum yellow; less distinctly trapezoidal; pronotal width 1.44–1.64 mm (mean: 1.54 mm), pronotal length 0.64–0.76 mm (mean: 0.72 mm), and pronotal length to width 0.44–0.49 (mean: 0.47). Elytron yellow with fine dark sutural margins, superficially punctuated; elytral length 3.20–3.65 mm (mean: 3.43 mm), elytral width 2.10–2.30 mm (mean: 2.22 mm), and maximal width of both elytra to length of elytron 0.63–0.68 (mean: 0.65) (Fig. 149). Meso- and metathorax yellow, legs yellow, tarsomeres brown; length of basi-metatarsus to metatibia 0.47–0.50 (mean: 0.49). Abdomen. Yellow. Male genitalia. Median lobe short, slightly conical in ventral view, apex with a U-shaped incision, flanked by one pair of sclerotized ridges (Fig. 150). Down-curved in lateral view, apically elongate with ventral sclerotized ridge; endophallic brush completely covered by tectum and median lobe, lacking sclerotized spiculae. Diagnosis. Neobarombiella frohnorum sp. n. can best be characterized by its slender body and antennomeres, colouring, and the superficial punctuation of the elytra. The only species that are similar in appearance, and occur syntopically, are N. grotefendi sp. n. and N. budongoensis sp. n. Neobarombiella grotefendi sp. n. is smaller, total length 3.35–3.80 mm (4.35–4.85 mm in N. frohnorum sp. n.); has more coarsely punctuated elytra; and a small but characteristic median lobe (Figs 149, 150, 157, 158). Neobarombiella budongoensis sp. n. has longer, more slender antennomeres and a different third to fourth antennomere ratio, 0.80–0.84 (0.63–0.69 in N. frohnorum sp. n.) (Figs 131, 151). Distribution. Recorded from a single location in Zambia. Type material. Holotype, male: “N. W. Rhodesia, Mwengwa., 27°40’E. 13°S., 1.i.1914., H. C. Dollman / H. C.

PARATYPES: 1 J 2 ♀♀, same data as holotype (2 ♀♀ in NMPC, 1 J in ZFMK). Description. Body length: 3.4–4.0 mm (mean: 3.7 mm, holotype 3.5 mm) (n = 4). Colouration. Labrum, labial and maxillary palpi brown or brownish-yellow; antennomeres I–VI (VII) yellow, becoming darker towards apex, following antennomeres brown and also darker towards apex. Head except for brown frontal tubercles, pronotum and elytron metallic green. Legs brownish-yellow or yellow; meso-, metathorax and abdomen entirely dark brown (Fig. 5). Sculpture and structures. Head. Antennomeres short, length ratio of second to third antennomere 0.78–0.86 (mean: 0.84), and length ratio of third to fourth antennomere 0.74–0.82 (mean: 0.78) (Figs 1, 3). Eyes disk-like and widely separated (Fig. 1), ratio of maximum eye width to interocular distance 0.44–0.45 (mean: 0.45). Thorax. Pronotum coarsely and deeply punctated; trapezoidal; pronotal width 1.2–1.4 mm (mean: 1.25 mm), pronotal length 0.7–0.8 mm (mean: 0.73 mm), and pronotal length to width ratio 0.57–0.59 (mean: 0.58). Elytron coarsely and deeply punctated; elytral length 2.6–2.9 mm (mean: 2.73 mm), elytral width 1.7–2.1 mm (mean: 1.84 mm), and ratio of maximal width of both elytra to length of elytron 0.65–0.71 (mean: 0.67) (Fig. 1). Metatibia less than double the length of basi-metatarsus; length ratio of basi-metatarsus to metatibia 0.40–0.42 (mean: 0.42) (Fig. 4). Abdomen. Male genitalia with short, slender, and parallel-sided median lobe; broad apically in dorsal view, and slightly down-curved in lateral view, with small sclerotised ventral projections alongside apical incision in ventral view (Fig. 2a); endophallic brush not protruding, basal orifice rectangular in ventral view; and dull. Variability. The two females differ from males in colouration: they have head and pronotum completely pale brown (Fig. 7). As many Neobarombiella species are extremely variable in colour (cf. BOLZ & WAGNER 2012), and because only four specimens of the new species are known, we cannot affirm the colour differences to the sexual dimorphism. Differential diagnosis. Neobarombiella socotrana sp. nov. is characterized by deep, irregular punctation of the elytra; elongate trapezoidal pronotum; the length ratio of the second and third antennomeres, each about two-thirds of the following antennomere (Fig. 4), and the distinct shape of the median lobe (Fig. 2). Tab. 1. Distinctive body measurement ratios of representative Neobarombiella species. Nevertheless, there are some rather similar species of Neobarombiella from continental sub-Saharan Africa, namely N. nigrocaerulea (Jacoby, 1897), N. nigrita (Jacoby, 1894), N. punctata (Laboissière, 1920), and N. punctatolineata (Jacoby, 1899). Most are discernible by rather short second, and more elongate third, antennomeres (for comparison of the relevant ratios see Tab. 1); in N. socotrana sp. nov., the second antennomere is more than two-thirds of the length of the third antennomere. In N. socotrana sp. nov., the pronotum is also comparatively long, whilst being shorter in other similar Neobarombiella species. Neobarombiella nigrita has broader and more convex elytra; N. punctata is smaller in size; the eyes of N. nigrocaerulea are smaller with wider interocular distance; whereas N. punctata has larger eyes and smaller interocular distance. The median lobe of N. nigrocaerulea is more conical apically and has a broader incision when compared to the nearly parallel-sided median lobe of N. socotrana sp. nov., which has a broad apex and small medial incision. Etymology. Named after Socotra Island; adjective. Distribution. So far this species is only known from the type locality: Tudhen, Socotra, Yemen.Published as part of Bolz, Helmut & Wagner, Thomas, 2014, A new AfrotropicalNeobarombiella species from Socotra Island (Coleoptera: Chrysomelidae: Galerucinae), pp. 277-281 in Acta Entomologica Musei Nationalis Pragae 54 on pages 278-280, DOI: 10.5281/zenodo.531226

Dimensions See Fig. 3A. Occurrence Northern Calcareous Alps, Tyrol, Austria, Norian–Rhaetian, Upper Triassic (Bolz 1971b; Mette et al. 2012); Romanian Continental Shelf, Black Sea, Rhaetian, Upper Triassic (this paper). Remarks Bairdiacypris cf. multidentata Bolz, 1971 has been reported from the Eiberg Member, K̂ssen Formation, outcropping at the Eiberg section in the Northern Calcareous Alps (Mette et al. 2012: 70), but no illustration and no discussion were provided to further discuss this attribution. Bolz (1971b) provided dimensions of complete carapaces, LV and RV: owing to the overlap of LV over RV in B. multidentata, the dimensions of carapaces are here treated as those of LV and all dimensions are plotted in Fig. 3A. Bolz (1971b) illustrated three specimens and stated that the material was not sufficient for an investigation of the ontogeny (Bolz 1971b: 231). Although the lack of illustrated specimens doesn’t allow a discussion of the morphological changes in B. multidentata through its development, the large dispersion of the H/L scatter plot of all specimens points to a mixture of ontogenetic stages, at least corresponding to five ontogenetic stages (A-4 to adult). The holotype appears to be an immature stage. The only measurable carapace found during the present analysis (Fig. 6E) is the smallest known carapace of B. multidentata and corresponds to a very young juvenile in the A-4 stage (Fig. 3A).Published as part of Forel, Marie-Béatrice & Grădinaru, Eugen, 2020, Rhaetian (Late Triassic) ostracods (Crustacea, Ostracoda) from the offshore prolongation of the North Dobrogean Orogen into the Romanian Black Sea shelf, pp. 1-83 in European Journal of Taxonomy 727 on pages 18-19, DOI: 10.5852/ejt.2020.727.1183, http://zenodo.org/record/431684

Elytron yellow with sharply delimited, very narrow outer elytral and sutural margins, finely and superficially punctuated; elytral length 2.35–3.10 mm (mean: 2.69 mm), elytral width 1.50–2.20 mm (mean: 1.84 mm), and maximal width of both elytra to length of elytron 0.64–0.71 (mean: 0.68) (Fig. 129). Meso- and metathorax brownish-yellow, legs entirely brown, length of basi-metatarsus to metatibia 0.47–0.55 (mean: 0.50). Abdomen. Yellowish-brown. Male genitalia. Median lobe short with V-shaped incision between one pair of sclerotized ridges in ventral view, dorso-ventrally compressed in lateral view, and elongate apically; endophallic brush large, totally covered by tectum and median lobe, with single pair of elongate spiculae (Fig. 130). Diagnosis. Neobarombiella budongoensis sp. n. can be characterised by its very narrow outer elytral and sutural margins and superficially punctuated elytra. The rather similar syntopical species N. frohnorum sp. n. has shorter, thicker antennomeres and the ratio of the third to the fourth antennomere differs, 0.63–0.69 (0.80–0.84 in N. budongoensis sp. n.) (Figs 131, 151). Neobarombiella grotefendi sp. n., also a sympatric species, has elytron with no outer or sutural margins and a very short, characteristic median lobe (Figs 129, 130, 157, 158). Distribution. Only known from Budongo Forest in western Uganda. Type material. Holotype, male: “ Uganda, District Masindi, Budongo Forest n. Sonso, 1°45’N, 31°35’E; 15.–25.I.97, Th.

Neobarombiella reichartzi Bolz & Wagner 2012, sp. n.
No full textNeobarombiella reichartzi sp. n. (Figs 75, 177–180) Etymology. Named after Stephan Reichartz, Helmut Bolz’s long-time friend. Total length. 4.35–5.55 mm (mean: 5.13 mm) (n=26). Head. Frons and vertex yellowish-brown to dark brown, labrum, labial and maxillary palpi yellowish-brown. Each antenna slender and brownish-yellow, basal and apical antennomeres darker (Fig. 177); length of second to third antennomere 0.67–0.78 (mean: 0.71), and length of third to fourth antennomere 0.60–0.71 (mean: 0.66) (Fig. 179). Eyes large with short interocular distance (Fig. 177), width of eye to interocular distance 0.53–0.65 (mean: 0.59). Thorax. Pronotum brownish-yellow with dark spots in posterior angles; pronotal width 1.68–2.00 mm (mean: 1.85 mm), pronotal length 0.74–0.94 mm (mean: 0.84 mm), and pronotal length to width 0.43–0.48 (mean: 0.45). Each elytron coarsely punctuated, brownish-yellow, with single black longitudinal line in basal two-thirds, rarely reaching elytral apex; longitudinal black spot in middle of each elytron, between line and outer elytral margin in about 50% of material studied; fragmented, sharply delimited, very narrow sutural margins visible in basal and apical third and very small black or brown spot on humerus (Fig. 177); elytral length 3.50–4.40 mm (mean: 4.05 mm), elytral width 2.20–3.10 mm (mean: 2.73 mm), and maximal width of both elytra to length of elytron 0.62–0.71 (mean: 0.65). Meso- and metathorax yellowish-brown, legs largely brownish-yellow; length of basimetatarsus to metatibia 0.45–0.57 (mean: 0.50). Abdomen. Entirely brownish-yellow or yellow. Male genitalia. Median lobe short and slightly conical in ventral view (Fig. 178a), with broad U-shaped incision; strongly down-curved in lateral view, with elongate tip (Fig. 178c); apical section lacking characteristic sclerotized structures; endophallic brush short with single pair of long spiculae, covered by tectum and median lobe. Diagnosis. Neobarombiella reichartzi sp. n. can most easily be distinguished from other species that occur syntopically by its colouring, because longitudinal lines are known from a small number of species in this genus. Only N. lineata sp. n., N. bilineata and N. vittigera have rather similar colouring. Neobarombiella lineata sp. n. has a single brown or black longitudinal line on each elytron, and thick brown or black sutural, and narrow outer elytral, margins (Fig. 161); on average it has longer second antennomeres, length of second to third antennomere 0.75–0.83 (mean: 0.80) (0.67–0.78 (mean: 0.71) in N. reichartzi sp. n.) (Figs 163, 179); its pronotum is longer and more slender, pronotal length to width 0.50–0.56 (0.43–0.48 in N. reichartzi sp. n.); and its eyes are more widely separated, width of eye to interocular distance is 0.40–0.47 (0.53–0.65 in N. reichartzi sp. n.) (Figs 161, 177). Neobarombiella vittigera has a similar distribution range, but has two black lines along each elytron; the pronotum is on average longer and more slender, pronotal length to width 0.47–0.53 (mean: 0.50) (0.43–0.48 (mean: 0.45) in N. reichartzi sp. n.) (Figs 72, 177); its antennomeres are much thicker (Figs 74, 179); and it can effectively be distinguished by its median lobe, which is long and straight with a V-shaped incision and a pair of small sclerotized ridges in ventral view (Fig. 73), in N. reichartzi sp. n the median lobe is short, distinctly down-curved apically, with a broad U-shaped incision and lacking any characteristic sclerotized structures (Fig. 178). Neobarombiella bilineata has similar colouring, but has a broad black sutural margin, and very narrow black outer elytral margins; its pronotum is longer and more slender, pronotal length to width 0.53–0.57 (0.43–0.48 in N. reichartzi sp. n.); and its eyes are smaller and more widely separated, width of eye to interocular distance 0.41–0.48 (0.53–0.65 in N. reichartzi sp. n.) (Figs 121, 177). All the other known species Neobarombiella do not have longitudinal black lines on the elytron. Distribution. Recorded from the Albertine Rift and the Great Rift Valley, from the eastern Democratic Republic of the Congo to northern Tanzania (Fig. 75). Type material.
