A Revision of the Nearctic Species of Hecamedoides Hendel (Diptera: Ephydridae)
2008
Abstract Species of the shore-fly genus Hecamedoides Hendel from the Nearctic Region are revised, including description of H. lattini, new species (Virginia. Stafford: Falmouth (38°19.2′N, 77°28.1′W; Rappahannock River; 9 m). To provide context and also to facilitate identification, diagnoses are provided for the tribe Discocerinini and genus in addition to a key to the genera and species, H. lattini and H. unispinosus, occurring in the New World. Diagnostic characters, especially of the male terminalia, are illustrated, and distribution maps are also provided.
New taxonomic twists in shore flies as revealed in discovery of Neozealides, a new genus from New Zealand (Diptera: Ephydridae)
2019
We describe Neozealides to accommodate two endemic species from New Zealand that were previously placed in the shore-fly genus Hyadina Haliday. Although similar to Hyadina, both species are more closely related to the Hyadina and Philygria groups of genera (Zatwarnicki & Ryczko 2014) than they are to species within Hyadina. To document these discoveries, we revise both species, placing them in Neozealides. Emphasis is given to structures of the male terminalia, which are fully illustrated. Detailed locality data and distribution maps for both species are provided. For perspective and to facilitate recognition of genera, the tribe Hyadinini is diagnosed and a key to genera from New Zeala…
Redescription of the forgotten New Caledonian weevil genus Callistomorphus Perroud, 1865 (Coleoptera, Curculionidae, Eugnomini) with descriptions of …
2019
Callistomorphusis one of the “forgotten” genera of the tribe Eugnomini inhabiting rain forest in New Caledonia. In this paper, the genusCallistomorphusand the type speciesC.farinosusare redescribed. Eight new species,Callistomorphusfundatussp. n.,C.gibbussp. n.,C.malleussp. n.,C.minimussp. n.,C.rutaisp. n.,C.szoltysisp. n.,C.torosussp. n.andC.turbidussp. n., are described, originating from the main island of New Caledonia. Illustrations and SEM photographs of the external morphology and the male and female terminalia are provided, as well as dorsal habitus colour photographs of the adults, a key to the species, a distribution map, and a discussion of the systematic position ofCallistomorphu…
<strong>A new species of <em>Pactola</em> Pascoe, 1876 (Coleoptera: Curculionidae: Eugnomini) from New Caledonia</strong>
2015
Pactola corporosa sp. n. is described from New Caledonia. Illustrations of body parts, terminalia of both sexes and distributional data of the new species are provided. The genus Pactola Pascoe, 1876 now contains thirteen species distributed in New Zealand, New Caledonia and Taevuni Island (Fiji Archipelago).
A New Aromatic Compound from the Stem Bark of Terminalia catappa
2015
A new aromatic compound 3,4,5-trimethoxyphenyl-1- O-(4-sulfo)-β-D-glucopyranoside (1), in addition to two triterpenoid saponins (chebuloside II, arjunoglucoside II), two triterpenes (arjunolic acid and 3-betulinic acid) and sitosterol-3- O-β-D-glucopyranoside have been isolated from the barks of Terminalia catappa. Their structures have been established on the basis of spectroscopic techniques (1D/2D NMR) and MS. Their cytotoxicity and anti-inflammatory activity, together with the antioxidant capacity of compound 1 were also evaluated.
A new genus and nine new species of Eugnomini (Coleoptera, Curculionidae) from New Caledonia
2016
Abstract The genus Rasilinus gen. n. is described (type species Rasilinus tchambicus sp. n.). Nine new species: Rasilinus bicolor sp. n., Rasilinus bifurcatus sp. n., Rasilinus bimaculatus sp. n., Rasilinus grandidens sp. n., Rasilinus longulus sp. n., Rasilinus subgemellus sp. n., Rasilinus subnodulus sp. n., Rasilinus tchambicus sp. n., Rasilinus virgatus sp. n. are described from New Caledonia. Illustrations of the external morphology, male and female terminalia, dorsal habitus colour photographs of the adults, key to species and distribution map of the new genus Rasilinus are provided.
Review of the shore-fly genus Oedenopiforma (Diptera: Ephydridae)
2012
The shore-fly genus Oedenopiforma Cogan is reviewed, including new information on Oedenopiforma argentea (distribution), Oedenopiforma javana (comb. nov. and O. orientalis syn. nov.), and Oedenopiforma vockerothi (sp. nov. from United Arab Emirates). Structures of the male terminalia of these three species, a diagnosis of the genus, and a key to the included genera of Dryxini and species of Oedenopiforma are presented. Resume´—Nous revisons le genre Oedenopiforma Cogan chez les ephydrides et apportons de nouvelles informations sur Oedenopiforma argentea (repartition), Oedenopiforma javana (nouvelle combinaison et O. orientalis nouvelle synonymie )e tOedenopiforma vockerothi (nouvelle espece…
A Revision of theniveaGroup of the Shore-Fly GenusDitrichophoraCresson (Diptera: Ephydridae)
2010
ABSTRACT Species of the nivea group (genus Ditrichophora Cresson) are revised. The group now includes four species of which one, D. gulkana (Alaska and Mongolia), is newly described. The group is now known to have a Holarctic distribution with two species, D. gulkana and D. nivea, being the first reported from the Nearctic Region. Another Asian species, D. brunnicosa, previously placed in Diclasiopa, is transferred to this group (genus Ditrichophora) and is also reported from Mongolia. To facilitate identification of these rare species, we have included diagnoses of the tribe, genus, and species group and have also provided an annotated key to Holarctic genera of the tribe Discocerinini and…
A revision of the new world species of Gymnoclasiopa Hendel (Diptera, Ephydridae)
2012
Species of the shore-fly genus Gymnoclasiopa Hendel from the New World are revised, including G. grecorum, sp. n. (Alaska. Juneau: Gastineau Channel, Thane Road (S Juneau; 58°16.9’N, 134°22.4’W)) and G. matanuska, sp. n. (Alaska. Matanuska-Susitna: Palmer (Matanuska River; 61°36.5’N, 149°04.1’W)). We also clarify the status of previously described species, including those now discovered to have Holarctic distributions and/or for which sexual dimorphism was not appreciated and the species was described twice, including G. montana (Cresson) as a syn. n. of G. bohemanni (Becker). Two species, G. bella (Mathis), comb. n., and G. chiapas (Mathis), comb. n., are transferred from Ditrichophora to …
Revision of the Shore-fly Genera Parahyadina Tonnoir and Malloch and New Zealand Hyadina Haliday (Diptera: Ephydridae).
2019
Two genera of the shore-fly tribe Hyadinini, Hyadina Haliday and Parahyadina Tonnoir & Malloch, are revised, and all species treated, save P. lacustris Tonnoir & Malloch, are described for the first time. The phylogenetic position of both genera within Hyadinini is presented along with confirming, morphological evidence. The New Zealand fauna of Hyadina is now limited to the single new species H. breva, and Parahyadina is expanded from being a monotypic genus based on P. lacustris to also include the following 9 endemic new species: P. angusta, P. atra, P. bifurcata, P. bulla, P. debilis, P. edmistoni, P. hennigi, P. irwini, and P. latistylis. For both genera, emphasis is given to s…
