No full textXestoleberis petrosa n. sp. Type series. Holotype: male UMUT RA32524 (Figs. 9 A–B’, E–F, J, 2M–N). Paratypes: male—UMUT RA32528 (Fig. 13 A–B, F1–F2), females—UMUT RA32526 (Fig. 9 C–D), UMUT RA32527 (Fig. 9 G–I, K), UMUT RA32529 (Fig. 13 D–E), UMUT RA32530 (Fig. 13 C). All type material was collected from the type locality. The holotype and paratypes are deposited at the University Museum, University of Tokyo, Japan. Valves on paleontological paper/cavity slides and soft parts mounted on glass slides. Additional paratypes preserved in 70% ethanol: two males and one female UMUT RA32525. Type locality. The rocky, open northwest coast of Tavewa Island in the Yasawa Group (P1, Fig. 1, Table 1); habitat: cushion like green algae (Dictyosphaeria versluysii). Etymology. Petrosa is Latin for rocky. This species was characteristic of algae growing on a rocky headland on the north west of Tavewa Island (Fig. 1). Diagnosis. Posterior end of carapace more widely rounded than anterior end. Carapace dorsoventrally flattened, coloration in living animals translucent, smooth and dotted with pores. Prominent ventral indentation two fifths of way from anterior. BO short segment with five terminating setae. Ejaculatory duct appears as two stacked layers separated by a single loop. Furca reduced to a short seta. Description. Carapace reniform, inflated and elongated (Figs. 2 M–N, 13A–F2). Maximum valve length range: 328 µm–377 µm, maximum valve height range: 104 µm–165 µm (Table 2). Maximum height at mid-length. Dorsal margin convex, ventral margin with conspicuous indentation. Wide anterior and narrow posterior vestibula. Merodont hinge. Carapace surface scattered with normal sieve pores. Normal simple pores concentrated on anterior and antero-ventral edges of valve. Scar pattern; topmost scar of posterior row of four adductor scars, trefoil and single anterior scar U-shaped. An1 with six podomeres; first two big and elongated, third–sixth small and quadrate (Fig. 9 A–A’). Second, third and fourth podomeres with one dorsal apical seta each, two dorsal apical setae on fifth podomere, sixth podomere with three fine and one slender, round-tipped terminating setae. An2 with one dorsal apical seta on first endopodite podomere, one dorsal and ventral medial seta and one ventral apical seta of second endopodite podomere (Fig. 9 B–B’). Pectinate terminating claws. Md coxa with six pointed teeth and two fine setae (Fig. 9 C– D). Palp with four podomeres: one dorsal and two ventral apical setae on second podomere, three medial setae at junction of second and third podomeres, two dorsal, two ventral medial setae and one ventral apical seta on third podomere, two medial setae at junction of third and fourth podomere and three stout terminating setae of fourth podomere. Mx with two segmented palp; first segment with three distal dorsal-apical setae and second segment with four terminating setae (Fig. 8 E–E’). Branchial plate with 12–14 setuled setae. BO symmetrical short segment with five terminating setae (Fig. 8 F). Basal setal formula for L5 1:2:1 and L6 and L7 1:1:1 (Fig. 8 G–I). Terminating claws of thoracic legs: L5 and L6 curved, L7 straight. Hp with asymmetrical triangular distal processes; one with sharply pointed tip, other with rounded tip (Fig. 8 J). Proximal ends of capsules sub-rounded and proximal support structure T-shaped. Furca, short fine setae on round base. Distribution. Out of the eight locations sampled for ostracods across Fiji, X. petrosa n. sp. was only collected at one site (type locality above). Specimens of X. petrosa n. sp. were also collected from a short red alga inhabiting the same rocky substrate as Dictyosphaeria versluysii (holotype habitat) and a bluegreen alga. Remarks. Carapace appearance and size of Xestoleberis petrosa n. sp. is similar to Xestoleberis planuventer Sato & Kamiya, 2007 (Fig. 13 Sato & Kamiya 2007) reported from Okinawa, Japan. However, the soft part morphologies of both species differ. X. planuventer —hirsute An2 and leg (L5, L6, L7) setae, crown of setae on the base of L6 and L7 claw and tip of L7 is serrated. These features are absent in X. petrosa n. sp. In addition, the ejaculatory duct arrangement, the shape of the distal processes and the proximal structure of the Hp of both species are different.Published as part of Chand, Prerna & Kamiya, Takahiro, 2016, Seven new species of the genus Xestoleberis (Ostracoda: Podocopida: Cytheroidea) from the Fiji Archipelago, pp. 325-348 in Zootaxa 4208 (4) on pages 340-342, DOI: 10.11646/zootaxa.4208.4.2, http://zenodo.org/record/20833
Quantitative comparison of adhesive toughness for various diamond films on Co-cemented tungsten carbide
No full textA new method of quantitative evaluation for the toughness of interface between thick diamond films and Co-cemented tungsten carbide (WC-Co) substrates is reported. This new method derives from the previously developed technique, which was applied for the quantitative evaluation of the adhesive toughness of discrete diamond crystallites on Co-cemented tungsten carbide (WC-Co) substrates [S. Kamiya et al., Diamond Relat. Mater. 9 (2000) 191-194] and has been applied here to evaluate the adhesive toughness of various diamond films on WC-Co cutting inserts. The adhesive toughness was successfully obtained to be in the 15-1.3 J/m(2) range and was depending on the morphology of the interface. (C) 2002 Elsevier Science B.V. All rights reserved

Legs yellowish brown. Head with fine frontal punctures, slightly larger than eye facets, 1.0–1.5 diameters apart. Eye densely faceted, interocular distance about 0.3 times of head width (Fig. 12c). Pronotal punctures slightly larger than those on frons, 1.0–1.5 diameters apart. Surface of elytra with punctures much larger than those on pronotum, separated by 1.0–2.0 diameters. Abdominal postcoxal lines complete and moderately recurved, reaching 3/4 length of ventrite 1 (Fig. 12d), area enclosed by the lines finely and sparsely punctate, irregularly distributed, broadly smooth along the lines; ventrite 1 with strongly coarse and sparse punctures at middle. Male genitalia. Penis slender, base of penis slightly broadened, narrowing to apex (Fig. 12e); tegmen with penis guide stout, swollen at basal half, then abruptly converging to pointed tip in lateral view (Fig. 12f), slightly longer than 2/3 length of parameres; in inner view, penis guide parallel sided from base to 3/4, then gradually tapering to pointed apex (Fig. 12g); parameres elongate oval with several setae at apex in lateral view (Fig. 12f).

Exopodite with at least two long setuled setae. Mx with two segmented palp; first segment with four distal dorsal-apical setae and second with three terminating setae (Fig. 3 F–F’). Branchial plate with 11 setuled setae. BO is symmetrical; short segment with numerous fine terminating setae (Fig. 3 G).</p> <p>Basal setal formula for L5 1+1:2:1 and L6 and L7 1+1:1:1 (Fig. 3 H–J). Terminating claws L5, L6 and L7 short and curved. Hp with asymmetrical, trigonal to sub-trigonal distal processes: one with wide, rounded end, other with tapered end (Fig. 3 K). Proximal ends of the capsules almost right-angled and proximal support structure shaped like pair of beaks placed back to back. Furca short fine seta on small rounded base.</p> <p> <b>Distribution.</b> <i>Xestoleberis becca</i> <b>n. sp.</b> occurs in four locations; including the holotype locality, this species also occurs in the southeast of Tavewa Island (P1), Korovou, Naviti Island (P2), and Viani, Vanua Levu (P5) (Fig. 1, Table 1). In addition to the holotype habitat, specimen collections were also made from short red algae (<i>Pterocladiella</i> sp. and <i>Gracilaria maramae</i>), a tall brown alga (<i>Sargassum</i> sp.) and sediments.</p> <p> <b>Remarks.</b> <i>Xestoleberis becca</i> <b>n. sp.</b> is similar to <i>Xestoleberis maculanitida</i> Titterton & Whatley, 2005 (Fig. 4, Nos. 15, 18, Pl. 3, Figs. 9 –16, Titterton & Whatley 2005) from Solomon Islands and <i>Xestoleberis paraporthedlandensis</i> Hartmann-Schröder, 1978 (Abb. 409–422, Tafel XIII Figs. 1–2, Hartmann-Schröder 1978) from Australia. In contrast with the mostly straight and simple (and some trifurcate) anterior marginal pores of <i>X. maculanitida</i>, the anterior marginal pores of <i>X. becca</i> are branching with at most five branches. The ejaculatory duct arrangements of <i>X. becca</i> and <i>X. paraporthedlandensis</i> vary. One of the Hp distal processes of <i>X. paraporthedlandensis</i> terminates into a seta while neither of the distal processes of <i>X. becca</i> <b>n. sp.</b> possesses any seta.</p>Published as part of <i>Chand, Prerna & Kamiya, Takahiro, 2016, Seven new species of the genus Xestoleberis (Ostracoda: Podocopida: Cytheroidea) from the Fiji Archipelago, pp. 325-348 in Zootaxa 4208 (4)</i> on pages 328-329, DOI: 10.11646/zootaxa.4208.4.2, <a href="http://zenodo.org/record/208330">http://zenodo.org/record/208330</a>
