BL = 12.8–16.1 mm, BW = 4.3–5.7 mm. Integument of body and appendages mostly dark brown, antennomeres III to XI, anterior and posterior margins of pronotum reddish brown. Head, pronotum, ventral surfaces and legs mostly covered with light brown pubescence intermixed with sparse pale hairs and dark brown setae, which are relatively sparser on head and pronotum. Head with three tawny vittae vaguely situated between the antennal tubercles and behind the upper eye lobes. Antennal scape and pedicel clothed with similarly colored pubescence as head, antennomeres III to VIII covered with fine yellowish pubescence, becoming denser on each apex. Pronotum with dense tawny pubescence covered on the tips of discal calli, around the base of lateral spines, and forming two longitudinal stripes situated at sides behind the midlength, which is not reaching posterior margin (these maculae are indistinct or almost absent in some individuals), and with a short narrow median stripe of yellowish pubescence at base. Scutellum densely clothed with yellowish pubescence except for a narrow glabrous midline. Elytra predominantly covered with fine light brown pubescence; each elytron provided with a large transverse velvety macula of blackish pubescence near apical third and a few same colored however much smaller spots behind it, and with a few small yellowish to pale pubescent spots mainly scattered along the lateral margin and on apical third.</p> <p>Head with frons rugose, coarsely punctate; lower eye lobe 1.7 times as long as width, nearly as tall as gena. Antennae moderately long, AL/BL = 1.5–1.8; scape rugose, coarsely punctate; antennomere III 1.4 times as long as scape, 1.2 times as long as antennomere IV.</p> <p>Pronotum 1.1 times as long as basal width, the width across lateral spines about 1.6 times of basal width; lateral spine short, thickened at base with subacute apex; disk moderately convex, sparsely and finely punctate, with three main prominent calli arranged in an inverted triangle, and a few setigerous granules converging at sides of the posterior callus. Scutellum rounded triangular.</p> <p>Elytra ca. 1.7 times as wide as pronotal base, EL/EW = 1.7; slightly widened from humeri to midlength, then gradually convergent toward conjointly rounded apices, moderately convex near basal two-thirds in lateral view; humeri broadly rounded, gently constricted, depressed dorsolaterally; each elytron with series of glabrous, mostly rounded granules (or tubercles) forming one longitudinal row and two carinae, of which one short mesal carina (or represented by a large oval swelling) is about quarter of elytral length situated at base near the scutellum, one lateral (sometimes indistinct) row close to the elytral epipleuron, extending from the humerus to apical two-fifths, and one dorsolateral carina extending behind the humeral depression to apical one-fourth, with posterior edge thickened and prominent, formed by several converging granules; disk also scattered with a few small granules mainly on basal half. Hind wings highly reduced, less than two-fifths of elytral length. Metaventrite shortened, subequal to mesoventral length. Legs moderately long; metafemora roughly reaching elytral apices.</p> <p> Male genitalia. Tergite VIII, tegmen and median lobe as in Fig. 20. Endophallus (Fig. 23) similar to that of <i>Echinovelleda guoliangi</i> (cf. Fig. 24) except for the MT+CT slightly constricted at basal third, MT and CT well defined by a dorsal constriction, CT relatively more curved dorsally and ltc relatively larger.</p> <p>Female (Fig. 12). BL = 13.3.– 17.4 mm, BW = 5.1–6.6 mm. Almost identical to male in general appearance. Body relatively stout. Appendages relatively shorter. AL/BL = 1.3. EL/EW = 1.6–1.7.</p> <p> <b>Etymology.</b> The new species is dedicated to Mu Mu, the daughter of the second author.</p> <p> <b>Distribution (Map 1).</b> China: Yunnan (Shizong County; Wenshan City; Gejiu City).</p> <p> <b>Remarks.</b> This new species superficially resembles <i>E</i>. <i>inermis</i>, however can be readily separated from it by the pronotum with light colored spots or stripes usually more distinct and well-defined, scutellum relatively lighter colored due to the dense light colored pubescent coverings, elytra markedly bearing a pair of large blackish subapical macula, appendages relatively longer, endophallus with MT not coarsely wrinkled, CT not constricted at ventral side, basal part of PB not constricted distally and bb roughly present. The similarities of the endophallic structures between this species and <i>E</i>. <i>guoliangi</i> indicate their close relationship (cf. Figs. 23 and 24). However it can be distinguishable by the external characters which associated with the loss of flight capability, i.e., the moderately constricted humeri, the shortened elytra with reduced hind wings and the shortened metaventrite, also by the comparatively short antennae.</p>Published as part of <i>Bi, Wen-Xuan, Mu, Chen & Lin, Mei-Ying, 2024, Taxonomic studies on the genera Echinovelleda Breuning, 1936 and Propedicellus Huang, Huang & Liu, 2020 (Coleoptera, Cerambycidae, Lamiinae, Lamiini), pp. 65-78 in Zootaxa 5399 (1)</i> on pages 74-75, DOI: 10.11646/zootaxa.5399.1.5, <a href="http://zenodo.org/record/10477787">http://zenodo.org/record/10477787</a>
Rhachicephala Truong, Zhao & Cai
No full text3. Rhachicephala Truong, Zhao & Cai, gen. nov. (Figs. 25–39) Type species. Rhachicephala dilatibia Truong, Zhao & Cai, sp. nov. Diagnostic characters. Head oval, distinctly deflected downwards in front of eyes and narrowed behind eyes, with two erect long spines behind bases of antenniferous tubercles (Figs. 25, 26); first antennal segment much longer than head, second segment longest, third and fourth segments thin and short; first rostral segment subequal in length to second segment; eyes large and protruded laterally. Pronotum transversely constricted before middle; lateral pronotal angles spinously produced; prosternum anteriorly armed with two strong spines; apex of scutellum spinously produced, postscutellum with a short spine (Fig. 26). Legs moderately long; fore femur much longer than fore tibia; basal two-fifths of fore tibia dilated outwards and compressed (Figs. 25, 27– 29); mid and hind femora beneath with a short spine subapically; posterior angle of each connexival segment spinously produced. Etymology. The new generic name, Rhachicephala, alludes to two erect long spines behind the bases of the antenniferous tubercles. The words rhachi and cephala mean spine and head, respectively, in Greek. Feminine. Remarks. The new genus is similar to Petalocheirus in the anterior angles of prosternum, the collar and posterior pronotal lateral angles spinously produced, fore tibia shorter than fore femur and the head deflected in front of eyes; but in the new genus the two long spines are inserted behind the bases of the antenniferous tubercles, the basal two-fifths of the fore tibia is dilated outwards (vs. head without spine behind base of antennal tubercle and fore tibia dilated its entire length in Petalocheirus). The general body plan of the new genus resembles that of Valentia Stål, but in the new genus the postscutellum has a short spine (vs. the postscutellum without spines, and the head without spine behind base of antennal tubercle also in genus Va l e n t i a). The new genus can be distinguished from the other Vietnamese genera of the reduviid subfamily Salyavatinae with the above key.Published as part of Truong, Xuan Lam, Zhao, Ping & Cai, Wan Zhi, 2007, Notes on the subfamily Salyavatinae (Hemiptera: Reduviidae) from Vietnam, with the description of a new genus, pp. 1-20 in Zootaxa 1615 on page 9, DOI: 10.5281/zenodo.17907

Impact damage of composite laminates with high-speed waterjet
No full textRain erosion may cause substantial damage to aircrafts during supersonic flight. Such event is investigated here via high-speed waterjet impact on composite laminates. An experimental setup is developed to produce waterjets with the speed up to 700m/s and a finite element model of the waterjet-composite impact event is established. The consistency of experiment and simulation results validates the adopted numerical methods. The distribution of the water-hammer pressure is non-uniform and the maximum pressure occurs near the contact periphery when the water is about to eject laterally. After a high-speed (300∼560m/s) waterjet impacts a composite laminate, the impacted surface depression is observed, and the typical surface damage presents a central region with no visible surface damage surrounded by a faded “failure ring” with resin removal, matrix cracking and minor fiber fracture. Delamination occurs at the interfaces of adjacent layers with unequal dimensions and longitudinal matrix cracking appears on the back surface. Both the velocity and the diameter of waterjets are crucial factors on CFRP damage extents. Water-hammer pressure, the stagnation pressure and propagation of stress waves are failure mechanisms for most matrix damage in CFRP impacted by waterjets.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Structural Integrity & Composite
