China [email protected] Chang-Chin Chen Technical Center, Tianjin New Wei San Industrial Company, Ltd. Tianjin, P.R. China [email protected] Abstract. Himaloaesalus gaoligongshanus Huang and Chen, new species (Coleoptera: Lucanidae: Aesalinae) is described from the Gaoligongshan Mts., Yunnan, China. It is the fi fth species of the genus Himaloaesalus Huang and Chen. This new species is similar to the Himalayan species Himaloaesalus himalayicus Kurosawa and H. saburoi Araya et al., from which it is distinguished. The male and female genitalia of all the known species of Hi- maloaesalus are illustrated. Dorcus yongreni Huang and Chen, new species (Coleoptera: Lucanidae: Lucaninae) is described from Ruili area, Yunnan, China. It belongs to the elegans group (Huang and Chen 2013). This new species is similar to the Indian species Dorcus apatani (Okuda and Maeda), new combination, originally described in Digonophorus Waterhouse. The male genitalia of both species are compared and illustrated. Introduction When preparing our third volume of “Stag Beetles of China”, some new discoveries were made, mainly by our friend, Mr. X.-D. Yang from western Yunnan, China. Two new species are described herein whilst the others will be included in our upcoming book in the next year. One of the here-described new species belongs to the recently erected genus Himaloaesalus Huang and Chen (Coleoptera: Lucanidae: Aesalinae), which consists of four known species (Kurosawa 1985, Araya et al. 1998, Araya and Yoshi- tomi 2003, Huang et al. 2009, Huang and Chen 2013). We have collected specimens of both sexes of all known species and compared their male and female genitalia. Another of the here-described new species belongs to the elegans group (Coleoptera: Lucanidae: Lucaninae) and is similar to a recently described Indian species (Okuda and Maeda 2015). We have dissected a topotypic male specimen of this Indian species for a detailed comparison with our new species. According to the morphological phylo- genetic analysis done by Huang and Chen (2013), the genus Digonophorus Waterhouse is a synonym of Dorcus MacLeay, so Digonophorus apatani Okuda and Maeda should be named as Dorcus apatani new combination. Materials and methods Specimens of Aesalini were collected from decayed logs in the fi eld as adults. Specimens of Dorcus were collected by a light trap at night. Specimens of adults were killed with ethyl acetate and dried. For Aesalini, we measured the pronotum-elytra length instead of body length because the dorsal surfaces of head, pronotum, and elytra in this tribe are not in a straight line and are often variable in length when the adult is alive. To examine the male and female genitalia, the last two abdominal segments were removed and treated with a 10% solution of potassium hydroxide and then preserved in 70% ethanol. Photographs were taken with an Olympus C-5050 camera mounted on Olympus SZX12 stereoscope. Terminology follows Holloway (1997, 1998), Huang et al. (2011) and Huang and Chen (2013). The type specimens are deposited in the following public and private collections: BMNH – Natural History Museum, London, United Kingdom CCCC – Chang-Chin Chen collection, Tianjin, China CHH – Hao Huang collection, Shanghai, China SHNU – Entomological Collection of Shanghai Normal University, China 2 • INSECTA MUNDI 0516, November 2016 HUANG AND CHEN Taxonomic Treatment Himaloaesalus gaoligongshanus Huang and Chen, new species (Fig. 1–21) Type material.

  • The Mystery of the Lesser Stag Beetle Dorcus Parallelipipedus (L.) (Coleoptera: Lucanidae) Mycangium Yeasts by Masahiko Tanahashi 1 and Maria Fremlin *2
    146 Bulletin of the Amateur Entomologists' Society The mystery of the lesser stag beetle Dorcus parallelipipedus (L.) (Coleoptera: Lucanidae) mycangium yeasts by Masahiko Tanahashi 1 and Maria Fremlin *2 1 National Institute of Advanced Industrial Science and Technology (AIST) Central 6, Tsukuba, Ibaraki 305-8566, J apan 2 25 Ireton Rd, Colch ester, Essex, CO3 3AT, UK - E-mail: [email protected] (Correspondence) Introduction The mycangium is a microbe-storage organ present in several wood-feeding invertebrates; for example, it has been known for some time that bark and ambrosia beetles, and even leaf-roller weevils carry symbiotic fungi in special structures on their bodies (Beaver, 1989; Kobayashi et al , 2008). However, this organ has only been discovered recently in stag beetles (Tanahashi et al. , 2010) and in a certain lizard beetle ( Toki et al ., 2012 ), probably because it is not an external structure. In their case, the mycangium is an ovipositor- associated organ, that is, an exoskeletal organ normally folded and hidden under the last tergal plate of the female’s abdomen. Remarkably, this organ is clearly represented, albeit without a description, in Franciscolo’s drawings of the dorsal view of the female reproductive system for a couple of Lucanidae species: Lucanus cervus and L. tetraodon (1997). However, he opted for ventral views of all the other species, including Dorcus parallelipipedus , in which case the mycangium is obscured by the reproductive organs. Since the author is no longer alive and the book is currently out of print, we reproduce below one of his diagrams with the mycangium marked by us (Figure 1).

  • Sugaring for Stag Beetles – Different Feeding Strategies of Lucanus
    Volume 70 • April 2011 57 Sugaring for stag beetles – different feeding strategies of Lucanus cervus and Dorcus paralellipipedus by Maria Fremlin (12447) 25 Ireton Rd, Colchester, Essex CO3 3AT, UK http://maria.fremlin.org and Paul Hendriks Hoofdstraat, 243 9828 PC Oostwold, The Netherlands [email protected] Introduction The stag beetle Lucanus cervus (L.) (Coleoptera: Lucanidae) will feed on sugary liquids either from sap runs or ripe juicy fruits; an old Kent name for stag beetles, cherry-eaters, attests to their strong liking for this fruit by males in particular (Krenn et al., 2002; Fremlin, 2004). They imbibe liquid with their feathery tongues, the two central setaceous parts between their mandibles. In some cases in the Netherlands, on sap runs up to 20 beetles have been seen licking sap, mating and males fighting (Gerrit Rekers, pers. comm. and seen by PH). In general the females stay for a few days, whereas males stay much longer. The large males often stand over the females, while smaller males try to get hold of the females and mate with them. The large males chase away the smaller ones, but sometimes a smaller male succeeds in mating with a female. Gerrit Rekers found several dead males in the vicinity of a sap run. In the UK, however, there are no records of stag beetles L. cervus gathering at sap runs although there are some from continental Europe (Chop, 1893; Tippmann, 1954; Mamonov, 1991; Tochtermann, 1992; Jansson, this issue). MF has observed in her urban area courtship behaviour very similar to that at sap runs, but in the vicinity of breeding sites, or freshly cut trees.

  • Male Mandible Trimorphism in the Stag Beetle Dorcus Rectus (Coleoptera: Lucanidae)
    Eur. J. Entomol. 110(1): 159–163, 2013 http://www.eje.cz/pdfs/110/1/159 ISSN 1210-5759 (print), 1802-8829 (online) Male mandible trimorphism in the stag beetle Dorcus rectus (Coleoptera: Lucanidae) YUTAKA IGUCHI Laboratory of Biology, Yamashita-cho 1-10-6, Okaya City, Nagano Prefecture, 394-0005, Japan; e-mail: [email protected] Key words. Lucanidae, Dorcus rectus, stag beetle, mandible, trimorphism, scaling relationship, discontinuous model Abstract. Males in many beetles show horn or mandible dimorphism. The stag beetle Dorcus rectus was assumed to have dimorphic males, but in this species there are not two but three visually distinct mandibular phenotypes. The aim of this study is to determine if the three phenotypes represent an allometric trimorphism in this species by studying the scaling relationship between body length and mandible length in 148 adult males and 31 adult females. The relationship was fitted using the following four statistical models; a simple line, a logistic curve, a continuous segmented line and a discontinuous line. The best-fitting model for the males was a dis- continuous line with two break points and that for the females a simple line. The male data was also well fitted by a logistic curve. The discontinuous linear model divided the males into three groups that were in good agreement with the three phenotypes. These results suggest that a subtle allometric trimorphism possibly exists in males of this species. Small males of this species have no dis- tinct teeth on their mandibles, whereas small males of D. striatipennis and D. curvidens, which are closely related to D.

The male jaws are used as weapons in fights, and evolve a more robust jaw morphology to enable them to take a firm they may exert a very forceful bite in some species. We investigated in grip on rivals and to avoid mechanical failure (Goyens et al., 2015a). 16 species whether and how the forcefulness of their bite is reflected In sexually dimorphic stag beetle species, males with larger jaws in their jaw morphology. We found a large range of maximal muscle have higher mating rates than males with smaller jaws (Harvey and forces (1.8–33 N; factor of 18). Species investing in large bite muscles Gange, 2006; Lagarde et al., 2005; Okada and Hasegawa, 2005; also have disproportionately large jaw volumes. They use this Okada and Miyatake, 2006; Shiokawa and Iwahashi, 2000). Owing additional jaw volume to elongate their jaws, increasing their to their longer jaws, they can reach further forward in aggressive chances of winning in battles.

In this study, mitochondrial genomes of two stag beetles, Sinodendron yunnanense and Prosopocoilus confucius, are sequenced for the first time. Both of their genomes consisted of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region. The mitogenome of S. yunnanense was 16,921 bp in length, and P. confucius was 16,951 bp. The location of the gene trnL(UUR), between the A þ T–rich and control region in S. yunnanense, is the first observed in Lucanidae. In P. confucius, an unexpected noncod- ing region of 580 bp was discovered. Maximum likelihood and Bayesian inference on the 13 mitochondrial PCGs were used to infer the phylogenetic relationships among 12 representative stag beetles and three scarab beetles.

Received: 25 February 2014; in revised form: 21 March 2014 / Accepted: 31 March 2014 / Published: 9 April 2014 Abstract: In most beetles, the hind wings are thin and fragile; when at rest, they are held over the back of the beetle. When the hind wing unfolds, it provides the necessary aerodynamic forces for flight. In this paper, we investigate the hydraulic mechanism of the unfolding process of the hind wings in Dorcus titanus platymelus (Oder: Coleoptera). The wing unfolding process of Dorcus titanus platymelus was examined using high speed camera sequences (400 frames/s), and the hydraulic pressure in the veins was measured with a biological pressure sensor and dynamic signal acquisition and analysis (DSA) during the expansion process.

O. Box 10420, Wellington SUMMARY New Zealand arthropod species and genera which require conservation research are identified. Although the list is incomplete, seventeen out of 40 topics have been noted as requiring urgent research and of these, 8 are considered extremely urgent. For each species there is a synopsis of distribution, conservation status and required research together with a ranking of the latter two. The location of the species in conservancies is noted. 1. INTRODUCTION A list of important research topics occurs in Ramsay et al. (1988) who mention community and species based topics. This report addresses in more detail which invertebrate species need research attention and ranks their importance. The list is not exhaustive because so many species remain undescribed or undiscovered. It is intended therefore, to review the list periodically. The report concentrates on the protected species because the Department of Conservation (DOC) has a statutory obligation (Wildlife Amendment Act 1980) to protect them and hence undertake any research which might be necessary.

Farrell Museum of Comparative Zoology, Department of Organismic and Evolutionary Biology, Harvard University, 26 Oxford Street, Cambridge, MA, USA article info abstract Article history: Stag beetles (family Lucanidae Latreille, 1804) are one of the earliest branching lineages of scarab beetles Received 23 September 2014 that are characterized by the striking development of the male mandibles. Despite stag beetles’ popularity Revised 6 February 2015 among traditional taxonomists and amateur collectors, there has been almost no study of lucanid relation- Accepted 17 February 2015 ships and evolution. Entomologists, including Jeannel (1942), have long recognized resemblance between Available online 28 February 2015 the austral stag beetles of the tribes Chiasognathini, Colophonini, Lamprimini, Pholidotini, Rhyssonotini, and Streptocerini, but this hypothesis of their close relationship across the continents has never been Keywords: tested. To gain further insight into lucanid phylogeny and biogeography, we reconstructed the first Biogeography molecular phylogeny of world stag beetles using DNA sequences from mitochondrial 16S rDNA, nuclear Chiasognathini Evolution 18S and 28S rDNA, and the nuclear protein-coding (NPC) gene wingless for 93 lucanid species representing Gondwana all extant subfamilies and 24 out of the 27 tribes, together with 14 representative samples of other early Lucanidae branching scarabaeoid families and two staphyliniform beetle families as outgroups. Both Bayesian infer- Phylogeny ence (BI) and maximum likelihood inference (MLI) strongly supported the monophyly of Lucanidae sensu lato that includes Diphyllostomatidae.
