The present work provides the first record of the genus Dinotrema Foerster, 1862 in the Neotropical region. Four new Neotropical species are described and illustrated: D. multiareolatum Peris-Felipo sp. nov., D. plaumanni Peris-Felipo sp. nov., D. subbidentatum Peris-Felipo sp. nov., and D. teutoniaense Peris-Felipo sp. nov. The following new combinations are suggested for Nearctic species: Dinotrema angusticornis (Fischer, 1969) comb. nov., D. armillariae (Fischer, 1969) comb. nov., D. bucculatricis (Fischer, 1969) comb. nov., D. caudatulum (Fischer, 1969) comb. nov., D. clayensis (Fischer, 1969) comb. nov., D. communis (Fischer, 1969) comb. nov., D. disstriae (Fischer,1969) comb. nov., D. pauperum (Fischer, 1969) comb. nov., D. saileri (Fischer, 1969) comb. nov., D. shannoni (Fischer, 1969) comb. nov. and D. sylvaticae (Fischer, 1969) comb. nov. An identifi cation key of the all New World Dinotrema species is provided.
Several recent studies have detected and described complexes of cryptic and sibling species in the genus Merodon (Diptera, Syrphidae). One representative of these complexes is the Merodon avidus complex that contains four sibling species, which have proven difficult to distinguish using traditional morphological characters. In the present study, we use two geometric morphometric approaches, as well as molecular characters of the 5’-end of the mtDNA COI gene, to delimit sibling taxa. Analyses based on these data were used to strengthen species boundaries within the complex, and to validate the status of a previously-recognized cryptic taxon from Lesvos Island (Greece), here described as Merodon megavidus Vujić & Radenković sp. nov. Geometric morphometric results of both wing and surstylus shape confirm the present classification for three sibling species-M. avidus (Rossi, 1790), M. moenium Wiedemann in Meigen, 1822 and M. ibericus Vujić, 2015-and, importantly, clearly discriminate the newly-described taxon Merodon megavidus sp. nov. In addition to our geometric morphometric results, supporting characters were obtained from molecular analyses of mtDNA COI sequences, which clearly differentiated M. megavidus sp. nov. from the other members of the M. avidus complex. Molecular analyses revealed that the earliest divergence of M. ibericus occurred around 800 ky BP, while the most recent separation happened between M. avidus and M. moenium around 87 ky BP.
Palaeosynthemis opaca sp. nov., a new dragonfly from Papua New Guinea (Anisoptera: Synthemistidae)
(2016)
A new species of the synthemistid genus Palaeosynthemis is described from the northern slopes of Papua New Guinea’s central cordillera. It is distinguished from all congeners by having females with large, nearly black patches at the bases of both wings. The male is most similar to P. cervula and P. feronia, but it differs from those species in having superior anal appendages less than three times as long as S10, basally enlarged and otherwise unarmed vs basally not enlarged (feronia) and almost four times as long as S10 and armed (cervula). Characters of the adults (both sexes) are illustrated and the affinities of the species are discussed.
Taxonomic supplement (2001 to 2015) to the catalogue of New Zealand Carabidae (Insecta: Coleoptera)
(2016)
A supplement to the “Carabidae (Insecta: Coleoptera): catalogue” published by Larochelle and Larivière (2001; Fauna of New Zealand 43), is provided. A total of 99 genera and 547 species and subspecies belonging to 21 tribes and 8 subfamilies of Carabidae (including Cicindelini and Rhysodini), is recorded for New Zealand. Endemism is high, with 93% of the species and subspecies as well as 62% of the genera recorded from this country only. Changes to the 2001 catalogue are documented. The synonymy and type locality of taxa described between 2001 and 2015 are also provided.
The Iranian fauna of Cucujidae, Laemophloeidae, and Silvanidae (Coleoptera: Cucujoidea) are summarized in this paper. In total 2 species of Cucujidae (1 genus: Pediacus Shuckard), 6 species of Laemophloeidae (3 genera: Cryptolestes Ganglbauer, Laemophloeus Dejean, and Placonotus MacLeay) and 7 species of Silvanidae (6 genera: Uleiota Latreille, Psammoecus Latreille, Ahasverus Gozis, Nausibius Lentz, Oryzaephilus Ganglbauer, Psammoecus Latreille, and Silvanus Latreille) are listed in this paper. Synonymies and distribution data are given.
The genus Rhinolaemus Steel is revised. A new island and a new country record are presented for the type species, R. maculatus Steel. A new species, R. niueensis Thomas, new species, is described from Niue, and Rhinolaemus tuberculatus (Grouvelle), new combination, is transferred from Laemophloeus (sens. lat.). The members of the genus are illustrated and a key to their identification is presented.
The first Cenozoic roproniid wasp from the Paleocene of Menat, France (Hymenoptera: Proctotrupoidea)
(2016)
Paleoropronia salamonei gen. et sp. nov., the first Cenozoic Roproniidae, is described from the Paleocene of Menat (Massif Central, France) on the basis of its fore wing venation. The Roproniidae range between the Mesozoic and the present time. P. salamonei gen. et sp. nov. was perhaps a parasitoid on tenthredinid sawfly larvae, as these insects were present in the wasp fauna from Menat outcrop.
A new species of laevicaudatan branchiopod, Lynceus insularis sp. nov., is described. It is reported from five sinkholes (dolines) in the southern part of New Caledonia. Lynceus insularis sp. nov. is closest to Lynceus species from Australia, but can be separated from these on the basis of clasper morphology and the form of the lamina abdominalis. Lynceus insularis sp. nov. is the first record of a remote insular endemic laevicaudatan. The habitats of the species may be threatened due to hydrological changes, reduction of water supply, acidification of fresh water, invasive species, and/or mining activities in the vicinity.
