Revision of the Clytra subfasciata species group (Coleoptera: Chrysomelidae: Cryptocephalinae: Clytrini)

The Clytra subfasciata species group is proposed, to comprise Clytra subfasciata Lacordaire, 1848 Lacordaire, J. T. (1848): Monographie des coléoptères subpentamères de la famille des phytophages. Tome second. Mémoires de la Société Royale des Sciences de Liége, 5, 1–890 pp. [Google Scholar], C. hajeki Medvedev &; Kantner, 2002 Medvedev, L. N., &; Kantner, F.

Qualitative examination of diatom diversity in black fly (Diptera: Simuliidae) gut contents across a mortality gradient after exposure to Bacillus thuringiensis subsp. israelensis de Barjac, 1978

While Bacillus thuringiensis subsp. israelensis de Barjac, 1978 de Barjac, H. (1978), ‘Une Nouvelle Variété de Bacillus thuringiensis Très Toxique Pour les Moustiques: B. thuringiensis var. israelensis Sérotype H14’, Comptes Rendus de l'Académie des Sciences de Paris 286D, 797–800. [Google Scholar] (Bti) is generally effective in reducing Simulium Latreille, 1802 Latreille, P.A. (1802–1803), Histoire Naturelle, Générale et Particulière des Crustacés et des insectes (Vol. 3), Paris: F. Dufart. [Google Scholar] pest levels, impaired toxicity has been identified. Diatoms are typically abundant in Simulium larval gut contents and thought to affect feeding behaviour and/or Bti ingestion. We sought to determine diatom composition in larval Simulium gut contents and periphyton in relation to mortality subsequent in situ Bti application across three stream reaches. Generally, lower larval mortality after Bti exposure was associated with comparatively greater diatom diversity inside gut contents, corresponding with an inverse relationship between periphyton diatom diversity and larval mortality across our study reaches. High profile diatoms inside gut contents were positively correlated with mortality, suggesting microbial morphology may affect Bti efficacy. Diatoms inside live larval guts were most similar to periphyton which indicates that these larvae may have been feeding less on lower quality detrital material and/or exhibiting comparatively greater benthic feeding.

The expression of aggression in the dobsonflies Corydalus magnus Contreras-Ramos, 1998 and Platyneuromus soror (Hagen, 1861) (Megaloptera: Corydalidae)

The expression of aggression in Megaloptera has received little attention, specifically for the adults of the subfamily Corydalinae. Among the New World species of Corydalinae, it is not known if aggression is triggered and expressed in the same way. Since two genera, Corydalus Latreille, 1802 Latreille, P.A. (1802), Histoire naturelle, générale et particulière des Crustacés et des Insectes. Ouvrage faisant suite aux ouvres de Leclerc Buffon et partie du cours complete d’Histoire naturelle rédigé par C.S. Sonnini, membre de plusieurs sociétés savantes. Vol. 3, Paris: F. Dufart. [Google Scholar] and Platyneuromus Weele, 1909 Weele, H.W. van der. (1909), ‘New Genera and Species of Megaloptera Latr.’, Notes from the Leyden Museum, 30, 249–253. [Google Scholar] have different courtship strategies, the effect of the social environment in the expression of aggression in two species of those genera, Corydalus magnus Contreras-Ramos, 1998 Contreras-Ramos, A. (1998), Systematics of the Dobsonfly genus Corydalus Latreille (Megaloptera: Corydalidae), Lanham, MD: Thomas Say Monographs, Entomological Society of America. [Google Scholar] and Platyneuromus soror (Hagen, 1861 Hagen, H.A. (1861), Synopsis of the Neuroptera of North America, with a List of the South American Species. Washington, DC: Smithsonian Institution.[Crossref] , [Google Scholar]), is examined here and compared with the known data in Corydalus bidenticulatus Contreras-Ramos, 1998 Contreras-Ramos, A. (1998), Systematics of the Dobsonfly genus Corydalus Latreille (Megaloptera: Corydalidae), Lanham, MD: Thomas Say Monographs, Entomological Society of America. [Google Scholar]. Our results suggest that the triggering of aggressive behaviours in the three species is similar. The decision of whether or not to fight is affected by their social environment: a male is aggressive against other males only when a female is present. Furthermore, the intensity of aggression does not differ among the three species. The behavioural observations support the idea that the mandibles of Corydalus males are used as weapons in male-male competition and during the courtship, but the post-ocular flanges of P. soror males are not involved in male-male competition (they use their short mandibles to bite). Conversely, data show that such a feature might act as a signal trait for female choice.     

A new species of Micragasma J. Sahlberg, 1900 (Coleoptera: Hydraenidae) from Crete

We describe a new species of Micragasma J. Sahlberg, 1900 (Coleoptera, Hydraenidae), which is here treated as a subgenus of Ochthebius Leach, 1815 Leach, W.E. (1815), ‘Entomology’, in The Edinburgh Encyclopaedia (Vol. 9), ed. D. Brewster, Balfour: Edinburgh, pp. 57–172. [Google Scholar]. The new species, O. (Micragasma) minoicus sp. n., was found at the margins of a coastal rockpool in the island of Crete. The species differs from the other two known species of Micragasma in both external and genital characters, but shares with them the presence of small setiferous tubercles on the surface of the head, pronotum and elytra, and a strong medial gibbosity on the head. In some characters, such as the structure and shape of the aedeagus, O. (M.) minoicus sp. n. is similar to other species of the genus Ochthebius, in particular of the subgenus Cobalius Rey, 1886 Rey, C. (1886), ‘Histoire naturelle des coléoptères de France (suite)’, Annales de la Société Linnéenne de Lyon, 32, 1–187, pl. 1–2.[Crossref] , [Google Scholar], typical of coastal rockpools.

Diving beetles of the genus Liodessus Guignot, 1953 in Colombia,with description of three new species (Coleoptera: Dytiscidae)

The Colombian species of the diving beetle genus Liodessus Guignot, 1939 Guignot, F. (1939), ‘Contribution à l’étude des Bidessus’, Bulletin de la Société d’Étude des Sciences Naturelles de Vaucluse, 10(4), 51–61. [Google Scholar] are revised. Liodessus bogotensis Guignot, 1953 Guignot, F. (1953), ‘Trente-neuvième note sur les hydrocanthares’, Revue Française d’Entomologie, 20, 109–117. [Google Scholar] is re-described. Three higher altitude species are new to science: Liodessus azufralis sp. n., L. quillacinga sp. n. and L. quimbaya sp. n. We also introduce two new subspecies, L. quillacinga cochaensis ssp. n. and L. quillacinga cumbalis ssp. n. We delineate the species using morphological structures such as male genital structure and beetle size, shape and colour pattern. Mitochondrial cox1 sequence data provided an additional character source. All the new species occur on higher altitudes above 2700 m and were collected in shallow, exposed peatland pools and puddles, mostly in Páramo. Liodessus obscurellus (LeConte, 1852), not yet recorded from Colombia, is included into the key due to its presence in nearby Costa Rica and Ecuador. The known distribution and habitat preferences of each species are outlined briefly.     

Integrative taxonomy of the cave-dwelling mysids of the genus Hemimysis

The genus Hemimysis (Malacostraca: Mysida: Mysidae) encompasses near-bottom, demersal and cave-dwelling mysids living in the marine, brackish and freshwater habitats around the European coast, from the Caspian Sea to the Scandinavian Peninsula. We conducted cladistic analysis of 52 morphological characters of all nine species and three subspecies of the genus Hemimysis. We also completed a molecular analysis based on three molecular markers of Hemimysis lamornae (Couch, 1856) found in the English Channel, the Mediterranean Sea, and the Black Sea. Both analyses did not support monophyly of Hemimysis lamornae. We thus consider the former subspecies H. lamornae pontica (Czerniavsky, 1882 Chevaldonné, P., &; Lejeusne, C. (2003). Regional warming‐induced species shift in north‐west Mediterranean marine caves. Ecology Letters, 6, 371–379. doi:10.1046/j.1461-0248.2003.00439.x.[Crossref], [Web of Science ®] , [Google Scholar]) and H. lamornae mediterranea Bacescu, 1936 Bacescu, M. (1936).

Annales Scientifiques de L’Universite de Jassy, 23, 331–338. [Google Scholar] as valid species. Analysis of mitochondrial cytochrome oxidase subunit I (COI) sequences of H. pontica shows no significant divergence between mysids living in the marine caves of Crimea and Bulgaria. Morphological trends in Hemimysis are discussed, H. pontica Czerniavsky, 1882 Chevaldonné, P., &; Lejeusne, C. (2003). Regional warming‐induced species shift in north‐west Mediterranean marine caves.

Early Oligocene Mammal Tracks from Southeastern France

Two new sites with mammalian footprints in the early Oligocene of southeastern France are described here. They represent one of the best preserved and more numerous record of tracks and trackways in the world with more than 320 ichnites. Many of those are arranged in trackways and sometimes show pes-manus impressions, a quite rare feature in mammalian ichnology. The ichnotaxonomic study indicates the presence of perissodactyls tracks referred to as Rhinoceripeda voconcense (Demathieu et al., 1984 Demathieu, G., Ginsburg, L., Guérin, C. and Truc, G. 1984. Etude paléontologique, ichnologique et paléoécologique du gisement oligocène de Saignon (bassin d’Apt, Vaucluse). Bulletin du Museum National d’Histoire Naturelle, Paris, 6: 153–183.  [Google Scholar]), artiodactyls footprints referred to as Megapecoripeda velox (Demathieu et al., 1984 Demathieu, G., Ginsburg, L., Guérin, C. and Truc, G. 1984. Etude paléontologique, ichnologique et paléoécologique du gisement oligocène de Saignon (bassin d’Apt, Vaucluse). Bulletin du Museum National d’Histoire Naturelle, Paris, 6: 153–183.  [Google Scholar]) and a carnivore footprint referred to as Bestiopeda sp. Vialov (1966) Vialov, O. S. 1966. Sledy zhiznedeyatelnosti organizmow i ikh paleontologicheskoe znachenie. Naukova Dumka, : 219 (in Russian) [Google Scholar]. They can be attributed to early Rhinocerotids, Lophiomerycids and/or Entelodonts and Mustelid-like carnivore, respectively. This study also aims at homogenizing the ichnotaxonomy used for mammal tracks where several genera were erected without a full review of the literature. All this taken together reveals a rich mammalian ichnofauna at a time period when no other fossils of mammals are known in the area and represents a good opportunity to provide state-of-the-art concerning the worldwide known sites that yielded mammalian footprints.     

Creating a human head finite element model using a multi-block approach for predicting skull response and brain pressure

To better understand head injuries, human head finite element (FE) models have been reported in the literature. In scenarios where the head is directly impacted and measurements of head accelerations are not available, a high-quality skull model, as well as a high-quality brain model, is needed to predict the effect of impact on the brain through the skull. Furthermore, predicting cranial bone fractures requires comprehensively validated skull models. Lastly, high-quality meshes for both the skull and brain are needed for accurate strain/stress predictions across the entire head. Hence, we adopted a multi-block approach to develop hexahedral meshes for the brain, skull, and scalp simultaneously, a first approach in its kind. We then validated our model against experimental data of brain pressures (Nahum et al., 1977 Nahum AM, Smith R, Ward CC. 1977. Intracranial pressure dynamics during head impact. Proceedings of the 21st Stapp Car Crash Conference, SAE Paper No. 770922; Warrendale, PA: Society of Automotive Engineers.[Crossref] , [Google Scholar]) and comprehensive skull responses (Yoganandan et al., 1995 Yoganandan N, Pintar FA, Sances A, Jr., Walsh PR, Ewing CL, Thomas DJ, Snyder RG. 1995. Biomechanics of skull fracture. J Neurotrauma. 12(4):659–668.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar], Yoganandan et al., 2004 Yoganandan N, Zhang J, Pintar FA. 2004. Force and acceleration corridors from lateral head impact. Traffic Injury Prevention. 5(4):368–373.[Taylor &; Francis Online] , [Google Scholar], and Raymond et al., 2009 Raymond D, Van Ee C, Crawford G, Bir C. 2009. Tolerance of the skull to blunt ballistic temporo-parietal impact. J Biomech. 42(15):2479–2485.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We concluded that a human head FE model was developed with capabilities to predict blunt- and ballistic-impact-induced skull fractures and pressure-related brain injuries.     

Chironomidae (Insecta: Diptera) from four protected areas in the state of Pernambuco,Brazil

New records and distributional notes of Chironomidae (Insecta, Diptera) are provided for four protected areas in the state of Pernambuco, northeastern Brazil. Additionally, we also present new records and update of distributional ranges from Brazil and the Neotropical Region. In total, 810 specimens belonging to 35 genera within the subfamilies Chironominae (22 taxa), Tanypodinae (11 taxa) and Orthocladiinae (2 taxa) were found. The subfamilies Chironominae and Tanypodinae predominated. Axarus Roback, 1980 Roback, S.S. (1980), ‘New name for Anceus Roback nec Anceus Risso’, Entomological News, 91, 32.[Web of Science ®] , [Google Scholar] and the Tanytarsus ortoni-group were recorded for the first time in the state of Pernambuco, while Nanocladius Kieffer, 1913a Kieffer, J.J. (1913b), ‘Nouvelle étude sur les Chironomides de l'Indian Museum de Calcutta’, Records of the Indian Museum, 9, 119–197. [Google Scholar] was recorded for the first time in the Northeast Region of Brazil. Our results make evident how much and where current knowledge of the northeastern Brazil chironomids remains fragmentary.     

Review of the genus Catomus Allard, 1876 (Coleoptera: Tenebrionidae) in Iran

A revision of fossil eagle owls (Aves: Strigiformes: Bubo) from Europe and the description of a new species,Bubo ibericus,from Cal Guardiola (NE Iberian Peninsula)

The European fossil record of eagle owls, genus Bubo Duméril 1806 Duméril AMC. 1806. Zoologie Analytique, ou Méthode Naturelle de Classification des Animaux, rendue plus Facile à l’Aide de Tableaux Synoptiques. Paris: H. L. Perronneau. [Google Scholar], is thought to extend back into the Miocene, but records of Bubo before the Middle Pleistocene are scarce and mainly constituted by non-diagnostic or fragmentary specimens. Apart from a number of fossil species of Bubo of uncertain validity, i.e. Bubo? florianae Kretzoi 1957 Kretzoi M. 1957. Bird remains from the Hipparion-fauna of Csákvár. Aquila. 63:239–248. [Google Scholar], Bubo lignitum Giebel 1860 Giebel CG. 1860. Zur Fauna der Braunkohlen Formation von Rippersroda in Thüringen. Zeitschrift für die Gesammten Naturwissenschaften. 16:147–153. [Google Scholar], and Bubo perpastus (Ballman 1976 Ballmann P. 1976. Fossile Vögel aus dem Neogen der Halbinsel Gargano (Italien). Zweiter Teil Scripta Geol. 38:1–59. [Google Scholar]), most fossil Bubo material is unassigned to species or assigned to the extant Bubo bubo (Linnaeus 1758) on the basis of size, especially for Early Pleistocene records. Given the ambiguity about the validity of the earliest records, here we revise the pre-Middle Pleistocene fossil record of Bubo in Europe. Our results indicate that, in Europe, Bubo is first recorded in the Late Pliocene/Early Pleistocene of Italy. By the Early Pleistocene, three taxa can be distinguished: Bubo ibericus sp. nov. from Cal Guardiola (Spain), Bubo sp. nov. indet. from Soave Cava Sud (Italy) and Bubo sp. from various sites across Europe. By the Middle Pleistocene, Eurasian environments experienced a substantial increase in severity and duration of glacial periods which might have led to the replacement of extinct species of Bubo by the recent B. bubo and Bubo scandiacus.     

First record of the bee genus Melitta from the Arabian Peninsula (Hymenoptera: Apoidea: Melittidae)

The oligolectic bee genus Melitta Kirby, 1802 (Melittidae: Melittinae) is recorded from the Arabian Peninsula for the first time, and from Saudi Arabia in particular. A series of females of Melitta schmiedeknechti Friese, 1898 Friese, H. (1898): Beiträge zur Bienenfauna von Aegypten. Természetrajzi Füzetek, 21, 303–313. [Google Scholar] were captured near Jabal al Mashār, Ha’il, Saudi Arabia, representing the first occurrence of this species, previously known across northern Africa and the southern Levant. Brief remarks and a key are provided for the two subspecific forms of M. schmiedeknechti.
