Systematics of Otarrha, a new Neotropical subgenus of Chimarra (Trichoptera: Philopotamidae)

Abstract. Subgenus Otarrha is established in genus Chimarra to include eighteen described species formerly placed either in subgenus Chimarra or unplaced to subgenus, and thirteen new species. All species are Neotropical, with collective distributions primarily in the Antilles (Greater and Lesser) and northern South America. One species occurs in southeastern Brazil and another species in Costa Rica and Panama. New species are described, recognized species redescribed (except for C. diannae and C. koki ), and a key to the identification of males in the subgenus is provided. Additionally, characters supporting monophyly of the subgenus and a phylogeny of its species are proposed. Described species transferred to this subgenus include Chimarra cubanorum Botosaneanu, C . diakis Flint, C . diannae Flint & Sykora, C . dominicana Flint, C . garciai Botosaneanu, C . guapa Botosaneanu, C . jamaicensis Flint, C . koki Botosaneanu, C . machaerophora Flint, C . patosa Ross, C . puertoricensis Flint, C . quadrifurcata Botosaneanu, C . retrorsa Flint, C . rossi Bueno-Soria, C . sensillata Flint, C . septemlobata Flint, C . septifera Flint and C . spinulifera Flint. Chimarra patosa is designated the type species of the subgenus. New species described in Otarrha include Chimarra amazonia (Peru), C . barinas (Venezuela), C . darlingtoni (Cuba), C . diaphora (Venezuela), C . incipiens (Venezuela), C . odonta (Brazil), C . parene (Peru), C . parilis (Peru), C . particeps (Peru), C . peruana (Peru), C . phthanorossi (Colombia), C . redonda (Dominican Republic) and C . tachuela (Venezuela). Two additional species are described and left incertae sedis to subgenus, Chimarra usitatissima Flint and C . angularis , sp.n. (Venezuela, Guyana).

Taxonomic Review of Creontiades Distant in Australia (Hemiptera: Miridae: Mirinae)

The two species of Creontiades Distant occurring in Australia, C. dilutus (Stål) (Australian endemic) and C. pacificus (Stål) (China, several countries in the Oriental and Australian regions including Tahiti and Micronesian islands) are redescribed, illustrated and their distributions are mapped. Megacoelum modestum (Distant) and C. virescens Reuter are synonymised with C. dilutus , and C. pallidifer (Walker) with C. pacificus. Available host plant information is provided for both species. C. dilutus , commonly known as green mirid, is a pest of cotton, potato, stone fruit, lucerne and other crops in certain parts of Australia. the generic limits of Creontiades and the closely related, world-wide distributed Megaceolum Fieber are reviewed based on examination of Australian species and the type species.     

A new pelagic predatory pike cichlid (Teleostei: Cichlidae: Crenicichla) from the C. mandelburgeri species complex with parallel and reticulate evolution

The Crenicichla mandelburgeri species complex from the Middle Paraná shows parallel evolution of ecomorphs to the unrelated C. missioneira species complex from the Uruguay River. In this article, we describe a new species from the C. mandelburgeri species complex that has evolved a parallel morphology and ecology to an unrelated species from the C. missioneira species complex (C. celidochilus). The new species is a pelagic predator that feeds predominantly on fishes and together with C. celidochilus is the only known pelagic species in the large riverine genus Crenicichla. The new species is endemic solely to a small tributary (the Urugua-í) of the Middle Paraná River where it is sympatric and partly syntopic with two other closely related endemic species that, however, differ strongly in their ecomorphologies (one is a generalistic invertivore and the other a specialized molluscivore). Mitochondrial DNA phylogeny finds the new species nested within the widespread C. mandelburgeri. Reduced genome-representation ddRAD analyses, however, demonstrate that this new species is of a hybrid origin and shares ancestry with C. ypo, one of the two studied sympatric species.

     

Species of the genus Crotonia (Acari: Cryptostigmata) from New Zealand

Five new species of Crotonia from New Zealand ( C. cervicorna, C. cupulata, C. longibulbula, C. tuberculata and C. reticulata ) are described as new, and two species ( C. cophinana (Michael 1908) and C. caudatis (Hammer 1966)) are redescribed. Five species groups of the genus are characterized and a key to the adequately described species of the world is presented.     

Six New Species of Dobsonflies from Venezuela (Megaloptera: Corydalidae: Corydalinae)

Six new species of dobsonflies (Megaloptera: Corydalidae: Corydalinae) from Venezuela are described and illustrated, two in the Neotropical genus Chloronia and four within the New World genus Corydalus. Chloronia contains 15 previously described species. The new species Chloronia gaianii and C. marthae, each from the southern tepui and Andean regions, appear to be most closely related to C. hieroglyphica (Rambur) and C. mirifica Navás, respectively. Corydalus contains 30 previously described species. The new species Corydalus clavijoi, of Andean affinity, appears most closely related to C. tesselatus Stitz; C. crossi, from Auyán-tepuí, might be closely related to C. nubilus Erichson; and both C. hayashii and C. mayri, from westernmost Guayana Shield area and Aracamuni tepuis, respectively, clearly belong in the distinct and monophyletic C. arpi Navás species group. Keys for identification of the Venezuelan species of both genera are provided.

Molecular systematics and biodiversity of the Cryptotis mexicanus group (Eulipotyphla: Soricidae): two new species from Honduras supported

Small-eared shrews of the genus Cryptotis (Mammalia: Eulipotyphla: Soricidae) are widespread in the northern Neotropics. Systematic studies of these shrews over the past two decades have revealed previously undocumented morphological and species diversity, resulting in a quadrupling of the number of recognized species. Unfortunately, a small proportion of the species in the genus have been included in molecular phylogenetic studies, and evolutionary relationships within the genus are incompletely known. Traditionally, species have been assigned to four or five morphologically defined ‘species groups’, but tests of the monophyly of some of these groups show weak support and relationships amongst species groups remain somewhat speculative. The largest species group is the C. mexicanus group inhabiting Mexico and northern Central America. We studied sequences from mitochondrial cytochrome-b and 16S genes, as well as nuclear ApoB and BRCA1 genes from 22 species of Cryptotis, including 15 species in the C. mexicanus group. Our combined analysis shows that the C. goldmani subgroup is very weakly supported as monophyletic; however, the C. mexicanus group as a whole is not monophyletic. Our molecular phylogenetic analyses confirm the distinctiveness of two newly described species (C. celaque and C. mccarthyi) from isolated highlands of western Honduras and illustrate their relationship with other species formerly considered part of a widespread C. goodwini.     

Revision of the Indo-Australian genus Cnematoplatys Schmidt with description of a new species from Queensland (Coleoptera: Scarabaeidae: Aphodiinae: Eupariini)

Abstract  The euparine genus Cnematoplatys Schmidt, with seven species, is reviewed, including one species, C. yorkensis described as new. The generic diagnosis is revised, a lectotype of the type species, C. benardi Schmidt, is designated, a key to the species is provided and pertinent morphological details are illustrated. All data on taxonomy and available data on distribution are given, and a cladistic analysis is included to test the monophyly of the genus.     

Taxonomic studies of the Halosphaeriaceae: Corollospora Werdermann

Taxonomic studies of the Halosphaeriaceae: Corollospora Werdermann. The problems in the classification of the genus Corollospora Halosphaeriaceae, Ascomycotina; are outlined. In Corollospora nine species have been described, five are retained in Corollospora (C. maritima, C. intermedia, C. lacera, C. pulchella, C. luteola ); one species is referred to Arenariomyces (A. trifurcatus ); and two new genera are described to accommodate the remaining species. Arenariomyces trifurcatus is lectotypified and a neotype has been deposited. Key to these taxa are given.     

The classification, evolution and biology of the Costa Rican species of Cryptophion (Hymenoptera: Ichneumonidae)

The six known Costa Rican species of the campoplegine ichneumonid genus Cryptophion Viereck are described and keyed. The distribution of species throughout Costa Rica is detailed based on data gathered by an intensive Malaise trap survey of the ichneumonids of the country. Five new species are recognized: C. espinozai. C. guillermoi, C. manueli. C. moragai and C. tickelli , and a sixth, C. inaequalipes (Cresson) redescribed. The monophyly of the genus is demonstrated and the phylogeny of the Costa Rican species reconstructed. Host relationships have been established for all species in Costa Rica; they develop as koinobiont endoparasitoids of first to third instar larvae of Sphingidae or Saturniidae. Analysis of the host relationships from a phylogenetic perspective suggested that the genus first evolved using macroglossine sphingid larvae feeding on rubiaceous understorey plants as hosts, and subsequently diversified to utilize sphingine sphingids and ceratocampine saturniids feeding on a variety of food-plants. Most species appear to be monophagous and oligophagy is apparently a derived feature of one sister-species pair, C. espinozai and C. manueli . In Santa Rosa National Park, Costa Rica, only a small proportion of the species of Saturniidae and Sphingidae present are used as hosts by Cryptophion species. No one host species is parasitized by more than one Cryptophion species. No species of Cryptophion is known to parasitize more than one host species feeding on any one plant species. The monophagous species C. inaequalipes is only known to develop in its sphingid host when that host is feeding on one of its two alternative food-plants.     

Descriptions and biological notes of Ctenoplectra bees from Southeast Asia and Taiwan (Hymenoptera: Apidae: Ctenoplectrini) with a new species from North Borneo

Six Ctenoplectra species are recorded from Southeast Asia and Taiwan. They are C. chalybea Smith, C. cornuta Gribodo, C. davidi Vachal, C. elsei Engel, C. sandakana sp. nov. and C. vagans Cockerell. Females of C. sandakana sp. nov. from North Borneo are similar to the mainland species C. chalybea , but differ mainly in the clypeal keel and the length of the antennal segments. The small blackish species, C. cornuta , is distributed in Myanmar, China and Taiwan and C. davidi is distributed in China, Russia and Taiwan; both species are seen at the flowers of Thladiantha . Ctenoplectra chalybea was collected from the Malay Peninsula, Myanmar, Taiwan and Vietnam. Ctenoplectra apicalis Smith and C. kelloggi Cockerell are allied to C. chalybea ; however, C. kelloggi is excluded from this study due to insufficient material. A key to the six known Ctenoplectra species is given. The large metallic species, C. chalybea and C. elsei , visit flowers of Momordica cochinchinensis (Lour.) Spreng. For the first time observations on the nest structures of C. chalybea and C. cornuta are presented. They choose remarkable places, such as artificial structures and buildings, for nest sites. The nest architecture prevents rain and direct sunlight from entering the nest. Bees used pre-existing holes or crevices in wood for nesting shelters and collected soil and appeared to mix it with some other substance to build nests. The cell lining materials and rubbing behaviors against the cell wall suggest that Ctenoplectra bees use floral oil mainly for cell lining materials.     

The bloodsucking biting midges of Argentina (Diptera: Ceratopogonidae)

A key is presented for the identification of the adults of 54 species of bloodsucking ceratopogonids, 51 of which are known inhabitants of Argentina, and Culicoides uruguayensis Ronderos, C. pifanoi Ortiz, and C. trilineatus Fox, which are known to occur in bordering Uruguay and Paraguay. Wing photographs are provided of females of the 45 species of Culicoides. Three new species of Culicoides Latreille from Northeastern Argentina are described and illustrated: C. austroparaensis Spinelli, C. bachmanni Spinelli, and C. williamsi Spinelli. The following six species are recorded for the first time from Argentina and/or bordering localities in Paraguay: Leptoconops brasiliensis (Lutz), C. gabaldoni Ortiz, C. ginesi Ortiz, C. pifanoi Ortiz, C. pseudocrescentis Tavares and Luna Dias, and C. trilineatus; and C. estevezae Ronderos and Spinelli is newly recorded from Misiones province of Argentina. C. lopesi Barretto is excluded from the Argentinean ceratopogonid fauna.
