Species of the genus Coelostoma Brullé, 1935 belonging to the subgenera Coelostoma s. str. and Holocoelostoma Mouchamps, 1958 from the Indian subcontinent are revised. Six species of Coelostoma s. str. and two species of Holocoelostoma are recognized, of which two are described as new: C. (Coelostoma) lyratum sp. nov. (India: Maharashtra) and C. (Coelostoma) nostocinum sp. nov. (India: Maharashtra, Goa, Karnataka, Kerala). Coelostoma (Coelostoma) fallaciosum Orchymont, 1936 and C. (Coelostoma) vividum Orchymont, 1936 were recorded for the first time from India and Bangladesh, respectively. Lectotypes are designated for C. aeneolum Régimbart, 1903 and Hydrobius stultus Walker, 1858. The previously confusing situation with Coelostoma (Holocoelostoma) stultum (Walker, 1858) and C. (Holocoelostoma) bhutanicum Jayaswal, 1972 is clarified based on new material of both species from India. Coelostoma sulcatum Pu, 1963 from China is removed from the synonymy of C. stultum and considered as a likely synonym of C. bhutanicum, a status which needs to be confirmed by a detailed study of type specimens. All species are (re)described and illustrated. Diagnosis of the subgenera of Coelostoma are modified in order to accommodate the species of the Indian subcontinent, resulting in narrowing down the concept of Coelostoma s. str. and widening the concept of Lachnocoelostoma Mouchamps, 1958.
Neoxorides Clément, 1938 is a small genus of ichneumonid wasps that develop on wood-boring beetles. We here revise the Western Palaearctic species of the genus, with a special focus on Sweden. A new species, N. striatus Johansson sp. nov. is described. Neoxorides opacus (Kokujev, 1903) stat. rev. is excluded from the synonymy with N. nitens (Gravenhorst, 1829) and reinstated as a valid species. The species is redescribed from European material. Neoxorides kissi (Ulbricht, 1911) is confirmed as a junior synonym of N. opacus. A neotype for N. opacus is designated. New characters to distinguish N. varipes (Holmgren, 1860), N. collaris (Gravenhorst, 1829) and N. montanus Oehlke, 1966 are presented. Almost all of the species treated are supported by DNA-barcoding. An illustrated key to the species occurring in the Western Palaearctic is provided, a prerequisite for making the genus accessible for future ecological and conservation studies.
A new genus and six new species of the family Gomphodesmidae from the Udzungwa Mts are described, including Pogoro alopias Rosenmejer & Enghoff sp. nov., Pogoro siren Rosenmejer & Enghoff sp. nov., Pogoropsis prolixopes Rosenmejer & Enghoff gen. et sp. nov., Emphysemastix frampt Olsen & Enghoff sp. nov., Agrophogonus hamulus Olsen & Enghoff sp. nov., and Agrophogonus pusillokiellandi Olsen & Enghoff sp. nov. Emphysemastix dracarys Olsen & Enghoff sp. nov. from Iringa city is described. Descriptive notes are given for Pogoro scharffi Hoffman, 2005, and Agrophogonus mwanihana Hoffmann, 2005. General gomphodesmid gonopod morphology is described and illustrated. A key to Udzungwa gomphodesmids is presented, as well as revised keys to all species of Emphysemastix and Agrophogonus. All gomphodesmid species from the Udzungwa Mts are mapped.
A new genus and species, Richerius marqueti gen. et sp. nov., of a crab of the family Hymenosomatidae MacLeay, 1838 are described from the inland waters of New Caledonia based on several specimens collected in two streams at altitudes of 180 m and 500 m, respectively. Richerius marqueti gen. et sp. nov. was compared to the other freshwater species known in New Caledonia, Odiomaris pilosus (A. Milne-Edwards, 1873), and to species of Amarinus Lucas, 1980, a genus comprising many freshwater species in New Zealand, Australia, Indonesia, the Philippines, and Papua New Guinea, but never recorded in New Caledonia. The barcode fragment of the COI mitochondrial gene was sequenced for seven specimens of R. marqueti gen. et sp. nov., and all sequences were deposited in GenBank. A brief and updated review of the New Caledonian marine and freshwater hymenosmatid fauna is provided.
A new fossil diatom species, Tertiarius minutulus sp. nov., is described from a sediment sequence DEEP-5045-1 of Lake Ohrid. The species is characterized by small valves (3.0–8.0 μm) with a round shape, a marginal area with radially arranged costae and a central uneven area with scattered areolae. Externally, the alveoli are occluded by cribra perforated by irregularly arranged pores. Internally, the alveoli are simple and areolae are occluded with domed cribra. The marginal fultoportulae are situated on costae close to the valve margin, located on every 5th or 7th thick internal costa. One to three fultoportulae are present on the valve face, each surrounded by two to three satellite pores. One rimoportula is present, positioned on a costa at the valve face / mantle junction. The species is compared with morphologically similar taxa and a detailed differential diagnosis is provided. Tertiarius minutulus sp. nov. is known only as a fossil taxon from Lake Ohrid, with a first occurrence during the early stages of lake basin development.
As a result of the integrative (morphology and DNA barcodes) revision of the Taiwanese species of the rove beetle genus Quedius belonging to the abnormalis group, in the subgenus Microsaurus, three valid hypogean species are reported for the fauna of this island: Quedius masuzoi Watanabe, 1989, Q. nishikawai Watanabe, 1991 and Q. adilus sp. nov. A new synonymy, Quedius masuzoi = Quedius chiangi Smetana, 1995 syn. nov., is established along with providing additional records, a larval description and bionomic information for this species. Finally, the biogeographic origin of the abnormalis group in Taiwan is discussed.
The Iranian species of the genus Anomalon Panzer, 1804 (Hymenoptera: Ichneumonidae: Anomaloninae) are reviewed. Four species, Anomalon amseli (Hedwig, 1961), A. chinense (Kokujev, 1915), A. cruentatum (Geoffroy, 1785) and A. narinae Zardouei & Rakhshani sp. nov., are found to occur in Iran. The female of A. amseli is described for the first time. Anomalon chinense is a new record for Iran. A key to the known Anomalon species of Iran is provided.
Ten species of Campodorus Förster, 1869 are reported from China and five species are new to science: C. albilineatus Sheng, Sun & Li sp. nov. from Guangxi Zhuang Autonomous Region in the Oriental part of China, C. punctatus Sheng, Sun & Li sp. nov. and C. rasilis Sheng, Sun & Li sp. nov. from Beijing, C. shandongicus Sheng, Sun & Li sp. nov. from Shandong Province and C. truncatus Sheng, Sun & Li, sp. nov. from Liaoning Province. Three species, C. ciliatus (Holmgren, 1857) and C. dauricus Kasparyan, 2005 collected from Liaoning Province and Mesoleius faciator Kasparyan, 2001 from Beijing, are new records for China. A key to species of Campodorus and a related genus known in China is provided.
Eight species of the genus Prodasineura Cowley, 1934 are recorded from Vietnam, including two newly described species: Prodasineura lancastrei sp. nov. and P. kong sp. nov. from north and central Vietnam. All species recorded are illustrated, including figures of morphological structures, and distribution maps and keys to the males and females are provided. We consider the record of P. laidlawi (Forster in Laidlaw, 1907) a misidentification and exclude it here.
A new species, Cryptomonas uralensis Martynenko, Gusev, Kulizin & Guseva sp. nov., is described from western slopes of the Ural Mountains (Russia) based on morphological and molecular data. Phylogenetic relationships inferred from nuclear SSU and LSU rDNA sequences show that the new species forms a clade with C. tetrapyrenoidosa Skuja emend. Hoef-Emden & Melkonian. Comparison of secondary structures of nuclear rDNA ITS2, including analysis of Compensatory Base Changes (CBC), confirms the separation between C. uralensis sp. nov. and C. tetrapyrenoidosa. Cell morphology and sizes of C. uralensis sp. nov. are very similar to C. tetrapyrenoidosa and C. pyrenoidifera, and C. uralensis sp. nov. may thus represent a species that can only be reliably identified using molecular data.
