DOI: 10.3897/dez.71.116185

Authors: Bjarte H. Jordal

Abstract: The peculiar Afrotropical bark beetle genus Xyloctonus Eichhoff, 1872 is revised and its biology described. Several unusual morphological features reflect adaptations to predator avoidance as they are highly exposed during mating externally on tree trunks and branches. Observations invariably indicate that males and females abandon the nest under bark at an early stage of progeny, the males already before eggs hatch, potentially engaging in subsequent additional matings. Most species have a clear preference for host plants in the plant family Sapotaceae. Although the genus is broadly distributed in forested parts of Africa, Madagascar and Mauritius, most species are found in the eastern part of this range. A Bayesian biogeographical analysis revealed a possible origin of the genus in Madagascar in the early Eocene, with subsequent colonisation of the southern African region in late Eocene. This contrasts with the closely-related xyloctonine genus Ctonoxylon Hagedorn, 1910, which is of western Congolian ancestry and more recently reached Madagascar multiple times during late Miocene. Two new species are described: Xyloctonus magnus sp. nov. from Madagascar and X. genieri sp. nov. from Burkina Faso. Synonyms are proposed for X. subcostatus Eggers, 1939 (= X. striatus Eggers, 1939) and X. scolytoides Eichhoff, 1872 (= X. latus Eggers, 1922). Identification to species is provided in a key illustrated with photographs of most species.

The genus Anacaena Thomson from the Ryukyu Archipelago of Japan (Coleoptera, Hydrophilidae) https://dez.pensoft.net/article/96994/ Deutsche Entomologische Zeitschrift 70(1): 143-157

DOI: 10.3897/dez.70.96994

Authors: Yûsuke N. Minoshima, Yuuki Kamite, Martin Fikáček

Abstract: We review the genus Anacaena Thomson, 1859 from the Ryukyu Archipelago, southern Japan. Three aquatic species are recognised: A. torikaii sp. nov. from Amami-ôshima Island, A. okinawana sp. nov. from Okinawa-jima Island and Kerama Islands, and A. kumejimana sp. nov. from Kumejima Island. All three species are very similar, with the morphology of the aedeagus being essential for a reliable identification. Dorsal colouration is also useful as a diagnostic character, despite some variation within species. We observe a possible geography-based variation between A. okinawana from Okinawa-jima I. and the neighbouring Kerama Is., but we treat both populations as conspecific based on genital morphology. Anacaena kumejimana and A. okinawana share many morphological characters possibly indicating their close relationship. We compare the endemism of aquatic Hydrophilidae in the Ryukyu Archipelago to that in other groups of aquatic beetles: the proportion of endemic species is higher in aquatic Hydrophilidae than in Dytiscidae, but much lower than in stream-inhabiting Hydraenidae and Elmidae. A list of Japanese species of Anacaena and a key to the Japanese species of the genus are provided.

A review of Himalcercyon stat. nov., with description of a new species from the Chinese Himalaya and an updated key to Asian genera of Megasternini (Coleoptera, Hydrophilidae) https://dez.pensoft.net/article/50078/ Deutsche Entomologische Zeitschrift 67(1): 35-49

DOI: 10.3897/dez.67.50078

Authors: Fenglong Jia, Zulong Liang, Martin Fikáček

Abstract: Himalcercyon Hebauer, 2002 stat. nov. is elevated to genus rank based on the unique form of its mesoventral elevation. The genus is reviewed, redescribed, and illustrated in detail. Two species are recognized: Himalcercyon mirus (Hebauer, 2002) comb. nov. from Nepal and H. franzi sp. nov. from Chinese Himalaya (Xizang Autonomous Region). Both species are illustrated and diagnosed. An updated key to the Asian genera of the tribe Megasternini (Coleoptera, Hydrophilidae, Sphaeridiinae) is provided, along with the SEM micrographs of ventral morphology of these genera. New replacement name Oreosternum nom. nov. is proposed for Oreocyon Hebauer, 2002 which is preoccupied by Oreocyon Marsh, 1872 (Mammalia, Oxyenidae) and Oreocyon Krumbiegel, 1949 (Mammalia, Canidae).

Species composition and diagnoses of leaf- and fruit-scarring beetles (Coleoptera, Chrysomelidae) infesting bananas and plantains (Zingiberales, Musaceae) in the Indian subcontinent https://dez.pensoft.net/article/47447/ Deutsche Entomologische Zeitschrift 66(2): 179-202

DOI: 10.3897/dez.66.47447

Authors: Kaniyarikkal D. Prathapan, Janakiraman Poorani, S. Amritha Kumari, C. Anuradha, Balakrishnan Padmanaban, Ramalingam Thanigairaj

Abstract: Leaf- and fruit-feeding chrysomelids (Coleoptera) on bananas and plantains (Musaceae, Zingiberales) cause major losses to banana growers in the northern and northeastern regions of India, Bangladesh, and other parts of Southeast Asia. The species composition of these beetles has not been studied so far in India and wrong names or wrong name combinations in the literature have caused confusion. Most particularly, the Central and South American apecies of Colaspis hypochlora Lefèvre (Chrysomelidae, Eumolpinae) has been erroneously reported as occurring in India and Bangladesh, and this name has been used for the Indian species. Based on extensive surveys for leaf- and fruit-feeding chrysomelids in the northern and northeastern regions of India from 2015 to 2019, three species of banana-feeding chrysomelids, namely, Basilepta subcostata (Jacoby) (Eumolpinae), Bhamoina varipes (Jacoby), and a new species, Sphaeroderma cruenta sp. nov. (Galerucinae, Alticini), are documented. Of these, the latter two are recorded as pests of banana in India for the first time. An illustrated diagnostic account of these three species is given to facilitate their identification by economic entomologists. COI sequences of populations of B. subcostata from Assam and Uttar Pradesh showed 98–100% homology, indicating that these populations are conspecific and that COI sequences can be used for rapid species determination. Brief notes on the biology and available management options for these pests are also given.

First known larva of omicrine genus Psalitrus d’Orchymont (Coleoptera, Hydrophilidae) https://dez.pensoft.net/article/34300/ Deutsche Entomologische Zeitschrift 66(1): 107-118

DOI: 10.3897/dez.66.34300

Authors: Yûsuke N. Minoshima

Abstract: The larval morphology of the water scavenger beetle Psalitrus yamatensis Hoshina & Satô, 2005 is described based on a specimen collected from Fukuoka Prefecture, Kyushu, Japan. This is the first description of the larval morphology of the hydrophilid genus Psalitrus d’Orchymont, 1919, as well as the first description of larval chaetotaxy of the tribe Omicrini. Species-level identification of the larva was performed using DNA barcoding of a molecular marker: a 658 bp fragment of the mitochondrial cytochrome oxidase I. A description including chaetotaxy of head capsule and head appendages, diagnosis, and illustrations of the larva is provided. Psalitrus larvae can be distinguished from other known larvae of the tribe Omicrini by the morphology of the head and legs. The larva shares characters with other known larvae of Omicrini; potential plesiomorphies are shared with Cylominae and aquatic hydrophilids; some characters are also shared with larvae of Megasternini and Sphaeridiini.

Abstract: Twenty eight species of the genus Quedius from Middle Asia comprising Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, are revised. Quedius altaicus Korge, 1962, Q. capitalis Eppelsheim, 1892, Q. fusicornis Luze, 1904, Q. solskyi Luze, 1904 and Q. cohaesus Eppelsheim, 1888 are redescribed. The following new synonymies are established: Q. solskyi Luze, 1904 = Q. asiaticus Bernhauer, 1918, syn. n.; Q. cohaesus Eppelsheim, 1888 = Q. turkmenicus Coiffait, 1969, syn. n., = Q. afghanicus Coiffait, 1977, syn. n.; Q. hauseri Bernhauer, 1918 = Q. peneckei Bernhauer, 1918, syn. n., = Q. ouzbekiscus Coiffait, 1969, syn. n.; Q. imitator Luze, 1904 = Q. tschinganensis Coiffait, 1969, syn. n.; Q. novus Eppelsheim, 1892 = Q. dzambulensis Coiffait, 1967, syn. n., Q. pseudonigriceps Reitter, 1909 = Q. kirklarensis Korge, 1971, syn. n. Lectotypes are designated for Q. asiaticus Bernhauer, 1918, Q. fusicornis Luze, 1904, Q. hauseri Bernhauer, 1918, Q. imitator Luze, 1904, Q. novus Eppelsheim, 1892 and Q. solskyi Luze, 1904. For all revised species, taxonomy, distribution and bionomics are summarized. Quedius fuliginosus (Gravenhorst, 1802), Q. sundukovi Smetana, 2003 and Q. pseudonigriceps Reitter, 1909 are recorded for Middle Asia for the first time. One species from the Q. coloratus-group, found to be new to science is not described due to shortage of material. Another possibly new species is tentatively identified as Q. fulvicollis Stephens, 1833 until the taxonomy of that widespread species is revised. An identification key to all species is provided.

Review of the flower-inhabiting water scavenger beetle genus Cycreon (Coleoptera, Hydrophilidae), with descriptions of new species and comments on its biology https://dez.pensoft.net/article/26261/ Deutsche Entomologische Zeitschrift 65(1): 99-115

DOI: 10.3897/dez.65.26261

Authors: Emmanuel Arriaga-Varela, Sin Yeng Wong, Alexander Kirejtshuk, Martin Fikácek

Abstract: The hydrophilid genus Cycreon Orchymont, 1919, previously known from two historical specimens only, is reviewed based on the numerous material collected recently from the inflorescences of various Araceae species in the Malay Peninsula and Borneo. Four species are recognized in the genus: C. sculpturatus Orchymont, 1919 from Sumatra, C. armandi Shatrovskiy, 2017 from Singapore, C. adolescens sp. n. from peninsular Malaysia, and C. floricola sp. n. with two subspecies, the nominotypical one from Peninsular Malaysia, and C. floricola borneanus subsp. n. from Borneo. All species are very similar, differing only by the pronotal punctation, shape of the clypeus and the mentum, and the form of the median lobe of the aedeagus. Specimens of C. floricola sp. n. and C. adolescens sp. n. were collected from inflorescences of various genera of the family Araceae. The field observations and analysis of mid gut contents indicates that they feed on organic material on internal organs of the inflorescences, including the pollen of the host plant. They were also observed to carry a large amount of pollen and are likely pollinators of their host species of Araceae.

New species and new combinations of Asian Batrisodes Reitter (Coleoptera, Staphylinidae, Pselaphinae), and synonymy of Batrisodellus Jeannel with Batrisodes https://dez.pensoft.net/article/4539/ Deutsche Entomologische Zeitschrift 62(1): 45-54

DOI: 10.3897/dez.62.4539

Authors: Zi-Wei Yin, Jia-Wei Shen, Li-Zhen Li

Abstract: Continuing surveys on the pselaphine fauna in China have revealed four undescribed species of the genus Batrisodes: Batrisodes angustelytratus sp. n. (with Pachycondyla ant) and B. longwangshanus sp. n. from Zhejiang, B. bamian sp. n. (with Pseudolasius ant) from Hunan, and B. songxiaobini sp. n. (with Formica ant) from Yunnan. The genus Batrisodellus is placed as a junior synonym of Batrisodes, syn. n.; this taxonomic act results in eight new combinations: Batrisodes cerberus, B. coprea, B. cristatus, B. fengtingae, B. laticollis, B. longulus, B. palpalis, and B. punctipennis. The Russian Far East species Basitrodes cornutus is transferred to Batrisodes, comb. n.

A taxonomic revision of Parallelodemas Faust from South China (Coleoptera, Curculionidae, Baridinae), with notes on sexually dimorphic characters https://dez.pensoft.net/article/4077/ Deutsche Entomologische Zeitschrift 61(2): 105-119

DOI: 10.3897/dez.61.8142

Authors: Jens Prena, Runzhi Zhang

Abstract: Nine species of Parallelodemas Faust are reported from China. In addition to the previously recorded P. impar Voss, we found P. docile Faust, P. vicinum Faust and the following six species newly described herein: P. dimetans sp. n., P. feae sp. n., P. petilum sp. n., P. plumosum sp. n., P. setifrons sp. n. and P. tumens sp. n. Parallelodemas tarsale Voss from Java is transferred to Lepidomyctides Yoshihara and Morimoto (comb. n.). Lectotypes are designated for P. docile, P. imperfectum Faust, P. perfectum Faust, P. tardum Faust and P. vicinum. Several morphological modifications with unknown functions are documented, illustrated and discussed. Males of some species have special setae on rostrum, antennal scape and mesotarsus. A medially notched epistome apparently occurs in both sexes but seems to wear off in females, probably during the preparation of oviposition sites. The mandible is unusual in having a convex, edentate inner face and incisor-like structures on the outer face.

A review of the genus Oosternum Sharp of the West Indies (Coleoptera: Hydrophilidae: Sphaeridiinae) https://dez.pensoft.net/article/1128/ Deutsche Entomologische Zeitschrift 61(1): 43-63

DOI: 10.3897/dez.61.7566

Authors: Albert Deler-Hernández, Franklyn Cala-Riquelme, Martin Fikácek

Abstract: The representatives of the genus Oosternum Sharp, 1882 occurring in the West Indies are revised. Ten species are recorded, of which seven are here described as new: Oosternum andersoni sp. n. (Cuba), O. bacharenge sp. n. (Dominican Republic), O. cercyonoides sp. n. (Jamaica), O. insulare sp. n. (Jamaica), O. luciae sp. n. (Saint Lucia), O. megnai sp. n. (Cuba) and O. pecki sp. n. (Dominican Republic). Diagnoses and detailed distributional data are also provided for O. sharpi Hansen, 1999 (widespread throughout both Greater and Lesser Antilles), O. latum Fikáček, Hebauer & Hansen, 2009 (endemic to St. Vincent) and an undescribed species from the Bahamas. A key to the West Indian Oosternum is provided and important diagnostic characters are illustrated. The West Indian fauna of Oosternum contains representatives of five different species groups and likely originated by multiple independent colonizations from the American continent. Within the study region, the highest diversity is known from the Greater Antilles, where two endemic species each in Cuba, Jamaica, and Hispaniola. The populations of O. sharpi were found to consist exclusively of females on all islands with the exception Puerto Rico.
