Developmental biology and ecological peculiarities of the relict longhorn beetle Callipogon relictus Semenov, 1899 (Coleoptera, Cerambycidae)

The developmental biology of the relict longhorn beetle Callipogon relictus Semenov, 1899 was studied from egg to adult in the laboratory for the first time. The molting dynamics and morphometric characteristics of all the larval instars were determined. The location of larvae within the tree trunk was investigated by nondestructive modern methods. The reproductive behavior and the process of oviposition are described. Individual development of the species under laboratory conditions, at constant temperature and humidity, took 44 months, suggesting that in the nature it extends over at least four years.

Areal of Callipogon relictus Semenov, 1899 (Coleoptera, Cerambycidae) in the Russian Far East

Data on the distribution of Callipogon relictus Semenov, 1899 over the Russian Far East were generalized. The distribution map for C. relictus is based upon long-term observations and collection materials by the leading institutions. The chronology was studied within the Russian geographic range of the species.

Distribution of the longhorned beetle Callipogon relictus (Coleoptera: Cerambycidae) in Northeast Asia

The distribution of the longhorned beetle Callipogon (Eoxenus) relictus Semenov, 1899 (Coleoptera: Cerambycidae) in Northeast Asia was summarized for the first time, based on the examination of comprehensive material. Callipogon relictus is the only representative of the genus Callipogon in the Palearctic region. Its distribution ranges from Shanxi province (China) in the south, northward through the Korean Peninsula to Amur Oblast (Russia), and from Inner Mongolia (China) in the west to the coastal area of the Russian Far East.

Newly developed fungal diet for artificial rearing of the endangered long‐horned beetle Callipogon relictus (Coleoptera: Cerambycidae)

In this study, we attempted to develop an artificial diet to effectively rear the endangered long‐horned beetle Callipogon relictus Semenov to facilitate restoration efforts for this species. Fungal mycelia of the white‐rot fungus Pleurotus florida (Eager) were, for the first time, provided as an artificial diet for the larvae of C. relictus. The experiment started on August 11, 2015 with 53 larvae being provisioned with the fungal diet under laboratory conditions (25°C, 60 % RH, L:D 0:24) without diapause. During the first year, 11 adults (4 males and 7 females, 20.8 % of the 53 larvae) emerged between September 10 and October 1, 2016. The body length of the largest male was 106.8 mm, and three of the four males exceeded 100 mm in length. These results show that a fungal diet for rearing C. relictus is useful not only for reducing the larval period to approximately 1/6 of the normal larval period in nature, but also for producing large adults. These results support the notion that fungus may provide nutritional benefits during the larval development of C. relictus, and also indicate that this species is fungivorous.

First Record of Callipogon relictus Semenov, 1899 (Coleoptera: Cerambycidae: Prioninae) from Lazovsky Nature Reserve, Primorsky Region, Russia

Lazovsky Nature Reserve is located on the eastern macroslope of the SikhoteAlin uplands between the Kievka and Black Rivers. Its southeastern border runs along the coast of the East Sea (or Sea of Japan). The reserve is comprised of the two small islands of Petrov and Beltsov. Administratively, the reserve is within the Lazovsky District of Primorsky region, Russia. Continual research of the fauna of insects and spiders within the territory of the reserve began in the 1970s. Due to the species diversity of insects, spiders and centipedes identified, Lazov sky Nature Reserve has established itself as one of the leading Russian bio di ver sity reserves. So far within the reserve and its surroundings, 6,108 spec ies from 290 families of insects have been recorded. Additionally, 231 species from 31 families of arachnids, as well as 18 species from 9 families of millipedes have also been recorded. The most comprehensively studied group is Coleoptera, which includes 2,183 species from 93 families. Of these, 172 species of 101 genera are longhorn beetles (Cerambycidae) (Sundukov 1998; Smirnov 2009). The relict longhorn beetle, Callipogon relictus Semenov, 1899, is a rare representative of the family in East Asia, in spite of being widespread in the Russian Far East, northeastern China, and Korean Peninsula. In Russia, the species is included in the Red Data Book of the Russian Federation (2001), but in the Pri mor sky region it is preserved only in the Ussuri Nature Reserve (Kuprin and Bez bor o dov, 2012; Kuprin et al., 2014). In March 2016, during a survey of the collection of the Zoological Museum of M. V. Lomonosov Moscow State University (ZMMU), the authors discovered one female specimen collected in the territory of Sudzuhinsky (Lazovsky) Re serve, which had not been included previously in the list of species of this reserve.

Isotomidae of Japan and the Asiatic part of Russia. I. Folsomia ‘inoculata’ group

Abstract The paper considers blind species of the genus Folsomia having two pairs of macrosetae on both meso- and metathorax and united in so-called ‘inoculata’ group, which is given a new, more laconic definition. Morphological characters important in the group’s taxonomy are discussed and a further division into four subgroups is proposed. Eight new species, i.e., F. amurica Potapov & Kuznetsova, sp. n., F. breviseta Potapov & Kuznetsova, sp. n., F. calcarea Potapov, sp. n., F. imparis Potapov & Hasegawa, sp. n., F. laconica Potapov & Kuznetsova, sp. n., F. tertia Potapov, sp. n., F. trisensilla Potapov, sp. n., and F. tubulata Potapov & Babenko, sp. n., are described. F. hidakana Uchida & Tamura and F. inoculata Stach are redescribed basing on new material, for the latter species the Stach’s individuals were also examined. A key to species of the group is given.

Survey research on the habitation and biological information of Callipogon relictus Semenov in Gwangneung forest, Korea and Ussurisky nature reserve, Russia (Coleoptera, Cerambycidae, Prioninae)

Abstract An investigation on the habitation of Callipogonrelictus Semenov, 1899 in Gwangneung forest was carried out, where the Korea National Arboretum is located. In an investigation spanning the last eleven years (2007–2017), 22 emergence holes, nine pupal chambers, six adults, and two larvae of C.relictus were identified. In this study, biological information about habitation of C.relictus is provided by comparing and combining the results of this investigation with a survey conducted in Ussurisky Nature Reserve, Russia, in 2015. The distribution is also reviewed to include the Korean Peninsula and a new location of South Korea is added to the distribution for C.relictus.

Morphological anomalies of endangered Korean relict long-horned beetle Callipogon relictus (Cerambycidae, Coleoptera) during ontogenesis and possible causes of their occurrence

Abstract This paper describes for the first time cases of exogenous morphological anomalies that occur during rearing of Callipogon relictus Semenov, 1899 in a laboratory setting. The highest frequency of the anomalies has been observed during pupation. It can be assumed that in beetles of this group, at final stages of ontogenesis, some abiotic factors such as humidity and temperature play an important role.
