New Discovery

ABSTRACTAbundant insect fossils have been recorded from the Lower Cretaceous of the Jiuquan Basin, but very few odonatans have been recorded. In this paper, a new damsel-dragonfly, Cretastenophlebia jiuquanensis sp. nov., is described from the Lower Cretaceous Zhonggou Formation in the Hanxiagou outcrop, Jiuquan Basin, northwestern China. This is the second species of the genus Cretastenophlebia Fleck et al., 2003. Cretastenophlebia jiuquanensis sp. nov. differs from Cretastenophlebia mongolica Fleck et al., 2003 in the presence of a broad discoidal triangle, a basally straight IR1 and less cells along the posterior wing margin between IR2 and RP2. Cretastenophlebia has been previously reported from the Lower Cretaceous of Bon-Tsagaan, central Mongolia. The new discovery expands the record of Cretastenophlebia to the Jiuquan Basin in Albian.

A New Species

Pelomedusoides is the most diverse clade of side-necked turtles and there is an extensive fossil record (de Broin, 1988; Lapparent de Broin, 2000; Gaffney et al., 2006, 2011) that dates back at least to the Barremian (Lower Cretaceous) (Romano et al., 2014). Its large fossil record evidences a greater diversity in the past, particularly at the end of the Mesozoic, and exhibits a good sampling of species that are represented by skull material (Gaffney et al., 2006, 2011). As a consequence, the most complete and recent phylogenetic hypotheses for this clade (e.g. Romano et al., 2014; Cadena, 2015) are based on matrices comprising a great amount of cranial characters derived largely from Gaffney et al. (2006, 2011). In addition, it is well established that shell characters show a lot of phenotypic plasticity, even in the fossil species (Romano, 2008; Gaffney et al., 2006, 2011). In most cases it consequently is not justified to rely on “diagnostic features” of poorly informative shell-only material for describing a new species. Because of that, most authors remark new morphotypes in the literature when such aberrant specimens are recovered, but do not make any nomenclatural act by proposing a new yet poorly supported species (e.g. Romano et al., 2013; Ferreira & Langer, 2013; Menegazzo et al., 2015). Unfortunately, such a supposedly new bothremydid turtle (Pleurodira: Bothremydidae) from the Early Paleocene of Brazil was recently described based on poorly diagnostic remains (Carvalho et al., 2016; hereafter CGB, for the authors initials) and a correction of this unfounded nomenclatural act is required. In addition I present some comments on shell only material from Brazil in order to guide splitter-taxonomists to stop describing poorly preserved fossil specimens as new species.

A new species of the peltoperlid genus Microperla Chu, 1928, Microperla qinlinga Chen, sp. nov. from Shaanxi Province of northwestern China is described and illustrated. The new species is characterized by the widely rounded ventral lobe in males and the extremely large and bilobed subgenital plate in female. In addition, the taxonomic history and current status of the genus Microperla is reviewed.

A description is given of a biogeographically interesting new species of Campodeidae (Diplura), Plusiocampa (Plusiocampa) tinoamorei sp. nov., a troglobiotic species found in the Sicilian Villasmundo and Scrivilleri caves. A second subterranean species already known from three caves in northwest Sicily near Palermo, Campodea (Campodea) majorica sicula Condé, 1957, also was studied. Both species were characterized with SEM. Each species belongs to a different monophyletic group: Plusiocampa s. str., with thoracic medial posterior macrosetae, and the group related to Campodea (Campodea) grassi Silvestri, 1912. Both groups are widely distributed on almost all of the large western Mediterranean islands. Nevertheless, although these two monophyletic groups have a different origin both could be dispersed via land connections between the mainland and the islands during the Messinian Age. This new discovery shows the great value of Sicilian caves that hold species with unique features and of high biogeographic significance.

The family of winter flies Trichoceridae is newly recorded for Mongolia. Four species, Trichocera (Metatrichocera) gigantea (Dahl), T. (M.) mackenziei (Dahl), T. (Saltrichocera) regelationis (Linnaeus) and T. (Trichocera) hiemalis (De Geer) are first recorded in Mongolia from sampling during 1996, 2003–2006, 2008. A new species, Trichocera (Saltrichocera) chuluuta, is described from specimens collected during the fieldwork of the Mongolian Aquatic Insect Survey Project in western and north-central Mongolia.

A New Species

Psychodidae Newman, 1834 is a large family of small, hairy nematoceran dipterans, comprising more than 2,600 described extant species. It is currently subdivided into seven subfamilies: Bruchomyiinae Alexander, 1920, Horaiellinae Enderlein, 1936, Phlebotominae Rondani, 1840, Psychodinae Newman, 1834, Sycoracinae Jung, 1954, Trichomyiinae Tonnoir, 1922, and the fossil subfamily Protopsychodinae Stebner et al., 2015. Some authors consider the group to consist of two families, i.e., Psychodidae and Phlebotomidae (Williams, 1993; Azar et al., 1999). This fact is founded only on the hematophagous and medically important aspects of the phlebotomines, nevertheless this arrangement is unfounded, because the phylogenetic relationships between the psychodid subfamilies remain unresolved, even if there is a possible sister-group relationship between the Phlebotominae and Psychodinae (Curler & Moulton, 2012). We consider recognizing phlebotomines as a separate family would necessitate also giving separate familial status to all the currently recognized subfamilies, which is not adopted here.

A New Species

Study of isolated leaf compressions from Prisayan Formation outcrops on the right side of the Irkutsk reservoir resulted in identification of a new species: Marskea cuspidata sp. nov. The species has a strong morphological affinity with M. heeriana N. Nosova et Kiritchkova and T. ketovae Teslenko. The epidermis original texture differs well the Marskea cuspidata sp. nov. from other representatives of the genus Marskea which are known from the Jurassic and Lower Cretaceous sediments of Europe, Central Asia and Siberia.
