Professor Da Ruan, Distinguished Visitor at Complutense University, Madrid
No full textThis short note is written as a contribution to the memory of Prof. Da Ruan. We shall try to reflect how he was entitled to stay two months (April-May 2011) as “Distinguisher Visitor” at Complutense University, Madrid, based upon his past collaborations without team, and pointing out some of the projects we jointly developed and launched during such a period. Beside the strictly scientific arguments towards his academic excellence, we want to stress his continuous support to explore new initiatives from a sincere and friendly collaboration.Depto. de Estadística e Investigación OperativaFac. de Ciencias MatemáticasTRUEpu

Optical evaluation on delamination buckling of composite laminate with impact damage
No full textThe delamination buckling and growth behaviors of a cross-ply composite laminate with damage induced by low velocity impact are investigated optically using three-dimensional digital image correlation (3D-DIC) method. For the 3D deformation measurement, the 3D-DIC setup comprised of two CCD cameras was adopted. The rectangle specimen was impacted under the impact energy of 7.0 J using a drop-weight testing machine, and the impact damage was detected by means of X-ray nondestructive evaluation (NDE) technique. The 3D deformation field measured with the optical system clearly reveals that the delamination buckling characteristic of the specimen mainly appears local deformation mode under compression after impact test. Moreover, the behavior of delamination growth evaluated by the 3D-DIC optical method reasonably agrees with the NDE observed damage result after compression

Cangshanaltica castanea had been described in Taizonia by Gruev (1985), a genus subsequently synonymized with Ivalia by Duckett et al. (2006). Due to homonymy with Ivalia castanea (Samuelson, 1966), a new name Ivalia gruevi was proposed for the species by Nadein (2013). Our placement of Gruev’s species in Cangshanaltica makes Nadein’s replacement name redundant (ICZN Art 59.4). We move the species to Cangshanaltica based on the following characters: (1) antennomere VII bearing a slight distal protrusion; (2) metaventrite bearing an anterior, horseshoe-like process reaching mesocoxae and covering the mesoventrite; (3) anterolateral pronotal setiferous pore placed in the middle of the pronotal margin; and (4) round, ovate, and convex body shape. Cangshanaltica castanea is similar to other Chinese Cangshanaltica species distributed in lowlands— C. sprynari, and C. fuanensis. The species can be distinguished using the key below. Type locality identity and distribution. The type locality “ China: Da-laen-saen” named by Walker has been discussed by authors who have revised J. Walker’s Chinese material (Schawaller & Aston 2017; Smetana 2009). According to their findings, the most likely type locality of C. castanea is China, Zhejiang prov., Ningbo pref., Dalei Shan (kDZ山), cca 29.5928 N, 121.2930 E. The second Walker locality in the BMNH material is “Nyew-tew I.” This locality refers most likely to the Nantian Dao Island (Éffl岛) in Zhejiang province, named “Nyew-tew Island” in 19th century Western maps, likely after the island’s peak Niutou Shan (牛Ë山). The second type locality should therefore be: China, Zhejiang prov., Ningbo pref., Nantian Dao (Éffl岛); cca 29.1361 N, 121.9388 E. Additional specimens assigned to the species complex of C. castanea were collected recently in Lu’aocun (炉岙村) in the Lishui prefecture, and in Hangzhou, both in Zhejiang province, China. Species identity and variability. Cangshanaltica castanea was described based on a type series collected by J. J. Walker. Besides the type series, we examined additional Walker material from the type locality (Da Laen Saen) and its surroundings (Nyew-tew I.). We also collected fresh DNA-grade specimens in southern Zhejiang —they strongly resemble several specimens from the C. castanea type series. All the specimens have similar morphology of external characters and female genitalia, however, the morphology of median lobe of aedeagus is quite variable among all specimens, even within the type material (fig. 3 G–H). Specimens also differ in elytral punctuation (in the holotype and most of Walker’s specimens, elytra have very feeble punctures, in several of Walker’s specimens and all the fresh specimens from Lishui, punctures are shallow but distinctly visible, forming a pitted elytral relief, similar to the surface of a golf ball), and size (males are up to 1.9 mm long). A similar species in external morphology is C. fuanensis Ruan, Konstantinov & Damaška, 2022, which differs in having a more slender median lobe of aedeagus, but is strongly divergent from the Lishui specimens based on DNA phylogenetic analyses (Damaška et al. 2021). This strong difference in both mitochondrial and nuclear DNA markers among the two morphologically similar species suggests that the C. castanea species complex can consist of more species which are similar in morphology but phylogenetically isolated from each other. Due to the lack of any DNA-grade material from the two historical collecting sites in Zhejiang, we decided not to treat any of the specimens with different genitalia morphology as distinct species. However, the variability of median lobe of aedeagus in C. castanea in our understanding is apparently larger than in other Cangshanaltica species. The species definition of C. castanea may therefore represent a species complex. A careful analysis of DNA and morphology based on fresh material from more localities in Zhejiang and around (including Walker’s sites) is the only way to yield enough information to resolve the C. castanea species complex.Published as part of Damaška, Albert František, Ruan, Yongying & Fikáček, Martin, 2022, The genus Cangshanaltica (Coleoptera: Chrysomelidae: Alticinae): overview, new species, and notes on species complexes, pp. 49-64 in Zootaxa 5219 (1) on pages 50-52, DOI: 10.11646/zootaxa.5219.1.2, http://zenodo.org/record/740814
