Three new species of the genus Mimetus Hentz, 1832 are described and named as M. bucerus sp. nov. (♂), M. lingbaoshanensis sp. nov. (♂♀) and M. yinae sp. nov. (♂♀). Detailed morphological descriptions, photos of the body and copulatory organs, line drawings of copulatory organs, as well as the distribution maps are provided.
Eleven species of Ctenopelma Holmgren, 1857 are reported from China. Five species are new to science: C. labiatum Sheng, Sun & Li sp. nov., from Ningxia Hui Autonomous Region, C. lii Sheng, Sun & Li sp. nov., from Liaoning province, C. rufofasciatum Sheng, Sun & Li sp. nov., reared from Cephalcia lariciphila (Wachtl, 1898) from Beijing, C. pineatum Sheng, Sun & Li sp. nov., reared from Acantholyda posticalis (Matsumura, 1912) and Cephalcia lariciphila from Beijing and Henan, Shanxi, Shan’xi, Liaoning, Jilin and Heilongjiang provinces, and C. spiraculare Sheng, Sun & Li sp. nov., reared from Cephalcia lariciphila from Henan and Shanxi provinces. One species, C. nigrum Holmgren, 1857, reared from Cephalcia lariciphila in Beijing, is a new record for China. Ctenopelma tomentosum (Desvignes, 1856) was reared from Neurotoma sibirica Gussakovskij, 1935 (new host record) in Liaoning province. A key to species of Ctenopelma known in China is provided.
Neopanorpa van der Weele, 1909 is the second largest genus in Panorpidae, and over 170 Oriental species have been reported hitherto. In this paper, we describe two new species: Neopanorpa luojishana sp. nov. and Neopanorpa xingmini sp. nov. from Southwest China. We also report the first discovery of the male of Neopanorpa ocellaris (Navás, 1908) from Guangxi and Guizhou, China, a species recorded from Sikkim previously. Neopanorpa brevivalvae Chou & Wang, 1988 is synonymized with Neopanorpa lungtaushana Cheng, 1957. In addition, Neopanorpa furcula nom. nov. is proposed for Neopanorpa furcata Zhou, 2005, a junior homonym preoccupied by Neopanorpa furcata (Hardwicke, 1825). The biogeographical implications of some Neopanorpa species are discussed in brief.
The gigas species group of the subgenus Canthidium (Neocanthidium) is defi ned and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identifi cation key and comments on the distributions of the species of the gigas group.
Four new species in the genus Amphicnaeia (Coleoptera: Cerambycidae: Lamiinae) are described: A. panamensis Wappes, Santos-Silva and Galileo and A. fuscofasciata Wappes, Santos-Silva and Galileo from Panama; A. bezarki Wappes, Santos-Silva and Galileo from Venezuela; and A. rileyi Wappes, Santos-Silva and Galileo from Costa Rica and Panama. Amphicnaeia affinis Breuning, 1940 is placed in synonymy with A. lineata Bates, 1866, and the species newly recorded from the Brazilian state of Minas Gerais. Amphicnaeia cordigera Aurivillius, 1920 is transferred to Rosalba Thomson, 1864, resulting in a new combination, and Rosalba rufescens Breuning, 1940, is found to be a junior synonym of the former. The holotypes of A. vitticollis Breuning, 1940, and A. villosula (Thomson, 1868) are illustrated for the first time.
Genera of Cryptognathini (Coleoptera: Coccinellidae) are discussed and a key to all recognized genera is provided. Cryptognatha is revised, and species of this genus are keyed. New species, authored by González and Hanley, are Cryptognatha pam, C. kellie, C. hannah, C. whitney, C. karla, C. celia, C. shelia, C. gayle, C. della and C. vicki. The following new synonymies are proposed: Cryptognatha simillima Sicard = Cryptognatha gemellata Mulsant, Cryptognatha fryii Crotch = Cryptognatha pudibunda Mulsant, Cryptognatha bryanti Brèthes = Cryptognatha pudibunda Mulsant. Lectotypes are here designated for Cryptognatha amicta Gorham, C. weisei Brèthes, C. pudibunda Mulsant and C. fryii Crotch.
Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp. nov., Synthecium rectangulatum Galea, sp. nov., Diphasia alternata Galea, sp. nov., Dynamena opposita Galea, sp. nov., Hydrallmania clavaformis Galea, sp. nov., Symplectoscyphus acutustriatus Galea, sp. nov., Symplectoscyphus elongatulus Galea, sp. nov. and Zygophylax niger Galea, sp. nov. The male and female gonothecae of Caledoniana decussata Galea, 2015, the female gonothecae of Caledoniana microgona Galea, 2015, as well as the gonothecae of both sexes of Solenoscyphus striatus Galea, 2015 are described for the first time. The systematic position of the genera Solenoscyphus Galea, 2015 and Caledoniana Galea, 2015 is discussed on both morphological and molecular grounds, and both are confidently placed within the family Staurothecidae Maronna et al., 2016. In light of the molecular data, the genera Billardia Totton, 1930 and Dictyocladium Allman, 1888 are assigned to the families Syntheciidae Marktanner-Turneretscher, 1890 and Symplectoscyphidae Maronna et al., 2016, respectively. The previously undescribed gonothecae of Hincksella neocaledonica Galea, 2015, and the male gonothecae of Sertularella tronconica Galea, 2016, were found. Thyroscyphus scorpioides Vervoort, 1993, a peculiar hydroid with putative stem nematothecae, is redescribed and assigned to the new genus Tuberocaulus Galea, gen. nov. Noteworthy new records from the study area are: Tasmanaria edentula (Bale, 1924), Hincksella sibogae Billard, 1918, Dictyocladium reticulatum (Kirchenpauer, 1884), Salacia sinuosa (Bale, 1888) and Billardia hyalina Vervoort & Watson, 2003. Most species are illustrated to facilitate their identification, and the morphology of the new ones is compared to that of their related congeners.
The genus Corambis Simon, 1901 includes five species; three of them, C. jacknicholsoni sp. nov., C. logunovi sp. nov. and C. pantherae sp. nov., are described here as new. The female of the C. foeldvarii Szűts, 2002 is described for the first time and a new generic diagnosis is proposed. The distribution and relationships of Corambis are discussed in terms of the geological and bioclimatic history of New Caledonia.
We provide the first comprehensive taxonomic revision of the poorly known South American butterfly genus Zischkaia Forster, 1964, hitherto regarded as including three described species. A phylogenetic analysis based on DNA sequence data shows that Zischkaia is monophyletic and consists of two morphologically diagnosable clades. Morphological characters and DNA 'barcodes' support the recognition of twelve species in the genus, a significant increase even for the relatively poorly studied subtribe Euptychiina. Consequently, nine new species are described and named herein, including Z. arctoa Nakahara, sp. nov., Z. chullachaki Nakahara & Zacca, sp. nov., Z. baku Zacca, Dolibaina & Dias, sp. nov., Z. arenisca Nakahara, Willmott & Hall, sp. nov., Z. argyrosflecha Nakahara, L. Miller & Huertas, sp. nov., Z. abanico Nakahara & Petit, sp. nov., Z. josti Nakahara & Kleckner, sp. nov., Z. mielkeorum Dolibaina, Dias & Zacca, sp. nov. and Z. warreni Dias, Zacca & Dolibaina, sp. nov. In addition, a neotype is designated for Satyrus pacarus Godart, [1824], and lectotypes are designated for Euptychia amalda Weymer, 1911, Euptychia fumata Butler, 1867 and Euptychia saundersii Butler, 1867.
