In the present paper, we review the fossil record of the Hydrometridae (Hemiptera, Gerromorpha) and present a new species from the Early Cretaceous Crato Formation of Northeastern Brazil, Christometra paradoxa gen. et sp. nov. This species is based on a new specimen (a female), as well as a previously figured one (a male), providing a rare case of preservation of sexually dimorphic features in the fossil record. This is the third species coming from this deposit, which is Aptian-Albian in age and the oldest deposit to have yielded hydrometrids so far. Only five other Mesozoic species are known, being slightly younger in age (Cenomanian). So far, phylogenetic analyses have recovered Cretaceous hydrometrids as basal relative to Cenozoic genera but, Christometra paradoxa exhibits several advanced characteristics that unite it in a clade together with the extant genera Hydrometra and Bacillometroides, in a more derived position than any previously known fossil hydrometrid. The present publication is registered in the Official Register of Zoological Nomenclature (Zoobank), under the registration number http://zoobank.org/urn:lsid:zoobank.org:pub:3CFA88AB-3CBC-4CCC-8196-698ECC863947. The registration number for the nomenclatural act of the genus is http://zoobank.org/urn:lsid:zoobank.org:act:84744426-1259-4864-8E3F-E43E0DAB2021, and that of the species is http://zoobank.org/urn:lsid:zoobank.org:act:23700AB2-F7AD-4F50-A5E7-CB28868079B2. 相似文献

Two new tribes in the Curculionoidea are described as the Anchineini Poinar and Legalov, n. trib. (Ithyceridae: Carinae) and Paleocryptorhynchini Poinar and Legalov, n. trib. (Curculionidae: Erirhininae). The genus Anchineus Poinar and Brown, 2009, n. placem. is transferred from the subfamily Curculioninae of the family Curculionidae to the subfamily Carinae of the family Ithyceridae. The genus Paleocryptorhynchus Poinar, 2009, n. placem. is transferred from the subfamily Cryptorhynchinae to the subfamily Erirhininae. The placement of the genus Mesophyletis Poinar, 2006 in the family Ithyceridae was confirmed. http://www.zoobank.org/urn:lsid:zoobank.org:pub:0C0039DD-7BC6-4A54-9282-F43C5606D68B 相似文献

In this faunistic survey, we give distributional records for 48 species and subspecies of Ichneumoninae found in Iran, mainly from Golestan and Azerbaijan-e-Grabi provinces. 13 of these taxa are new for the Iranian fauna. Three Iranian species are new to science and described and illustrated, namely Coelichneumon iranicus Riedel sp. n., Coelichneumon melanocastaneus Riedel sp. n., and Coelichneumon nigrifrons Riedel sp. n. http://www.zoobank.org/urn:lsid:zoobank.org:pub:BE8AC3A5-D40E-4D78-BB05-C0DEDFC5C47B 相似文献

In a survey of the mollusc fauna of the Ceyhan River Basin, including rivers, natural lakes, dam lakes and springs between June 2008 and September 2014, a total of 20 species of Gastropoda and 8 species of Bivalvia were identified. Two of these species are new to science, and for one of them a new genus is erected: the hydrobiid Hemite ceyhanensis gen. n., sp. n., and the bithyniid Pseudobithynia cocussusica sp. n. http://www.zoobank.org/urn:lsid:zoobank.org:pub:DE5FFC19-13CD-4B81-B74E-80059E781518 相似文献

Sesara triodon n.sp. is described from the Phu Pha Lom limestone area in Loei, northeastern Thailand. It possesses a small and depressed–conoid, transparent shell with a shiny external surface. The aperture possesses three apertural teeth, in contrast to other Thai species, Sesara parva Solem, 1966 (two teeth) and Sesara megalodon Blanford, 1902 (four teeth). The genital system of the new species has some distinctive characters, including a vagina longer than the free oviduct, and the epiphallic retractor caecum is rounded and bulbous. The radula has 104 rather straight rows of teeth, with each row having74–81 teeth. This is the easternmost record of the genus Sesara in Thailand. http://zoobank.org/urn:lsid:zoobank.org:pub:52EF0AB6-1E17-4B96-BC6F-4257FE5FBF00 相似文献

A new subspecies of the Bille’s Lycian Salamander Lyciasalamandra billae is described from four localities in the vicinity of Geyikbay?r? nearby Antalya, Turkey. It is distinguished from the nominotypical subspecies by colouration and surface pattern. The distribution area of the new subspecies is nested within the range of Lyciasalamandra antalyana, with L. a. gocmeni bordering in the north and the range of L. a. antalyana bordering in the south. New localities of both L. antalyana subspecies are reported. http://www.zoobank.org/urn:lsid:zoobank.org:pub:8F541E98-61F3-4EDD-A432614B0A250711 相似文献
