Phylogeny and Taxonomy of the Risa Genus-group (Diptera: Ephydridae), with Description of a New Genus from Australia
2023
The systematic and somewhat controversial history of Risa Becker is presented, and its relationship with Diasemocera Bezzi (tribe Psilopini, Ephydridae) is documented by morphological evidence and an association with host plants in the family Amaranthaceae. The tribe Risini Papp (as Risidae) is synonymized with Psilopini Cresson. Notorisa gen. nov., from Australia, is described (type species: Notorisa mcalpinei sp. nov.; Australia. Victoria: Big Desert National Park, near Lake Hindmarsh; 36°03.7'S 141°54.8'E). Achaetorisa Papp is retained as a subgenus within Risa and includes five species, including two new combinations: Risa brevicornis (Papp) comb. nov., Risa salsolae (Mathis & Zatwa…
An overview of the Ephydridae (Diptera) of Saudi Arabia
2019
Despite the species richness of Ephydridae world-wide (2000 species) and its prominent environmental roles as a minor pest and as a food for wildlife, only 13 species have been recorded from Saudi Arabia. Between 2012 and 2016, a biodiversity study of Diptera was conducted at Jazan, Asir, and Najran in south-western Saudi Arabia, at 22 sites, was performed mainly using Malaise traps and sweep nets. In this study, 43 known species of Ephydridae were identified, 37 of them for the first time from southwestern Saudi Arabia and 16 from Arabian Peninsula. This brings the total number of Ephydridae species in Saudi Arabia to 49 (including previous records). There were a further four species, whic…
p class="ZootaxaTitle"First description of immature stages of Gastropini, Gastrops willistoni Cresson (Diptera: Ephydridae) preying on eggs in a foam…
2020
The third instar larva and puparium of Gastrops willistoni Cresson (Diptera: Ephydridae), preying on eggs in a foam nest of Leptodactylus knudseni Heyer (Anura: Leptodactylidae), in a central Amazonian dryland forest (Brazil) are described for the first time. The fusiform larva has a short breathing tube, its anterior spiracles are fan-shaped and posterior spiracles with three spircular openings. Pupa is ovoid with a broad anterior margin and bifurcate posterior tip. The taxonomic relationship of the frog egg predators, Gastrops Williston and Typopsilopa Cresson, are discussed.
First Nearctic Record of Hydrellia albilabris (Meigen) (Diptera: Ephydridae), a Leafminer of Duckweed (Araceae: Lemnoideae), with Comments on Related…
2019
Hydrellia albilabris (Meigen) (Diptera: Ephydridae) is recorded in the Nearctic Region for the first time. Its biology and immature stages are documented, and other miners in duckweeds (Araceae: Lemnoideae) are discussed. One new combination is proposed: Hydrellia jinpingensis (Zhang, Yang, and Hayashi) is transferred from Cavatorella.
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…
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…
Phylogeny of Hyadinini (Diptera: Ephydridae) with an Emphasis on Structures of the Proboscis
2014
Abstract. The shape of adult mouthparts (proboscis) of all genera of Hyadinini (Diptera: Ephydridae) is provided, including variability of cibarium, lacinia and the number of pseudotracheae. Its usage in phylogenetic construction is documented. All ten genera are diagnosed, including the genus Lytogaster, which is formally restored from synonymy with Hyadina. The ventral receptacle of four genera (Garifuna, Parahyadina, Parydroptera and Pelinoides) and the male terminalia of Parahyadina are presented for the first time. Monophyly of the tribe is discussed and the relationships among genera of Hyadinini are proposed. Ten Hyadinini genera are grouped into four lineages 1) Pelina group with Pe…
Heterogeneity in shore flies – the case ofGlenantheHaliday (Diptera: Ephydridae) in the Old World
2011
Abstract Old World species of the genus Glenanthe are treated comprehensively with an emphasis on the unusually diverse morphological heterogeneity discovered in structures of the male terminalia. As perspective for this treatment, the tribe Lipochaetini, in which Glenanthe is placed, is characterized and discussed, and an annotated key to the four included genera is provided to facilitate their identification. Glenanthe is demonstrated to be a monophyletic lineage within Lipochaetini. Seven Old World species of Glenanthe are now known, including two new Afrotropical species as follows (type locality in parenthesis): G. namibia n. sp. (Namibia. Mukwe: Divuju: Okavango River [18°04’04”S, 21°…
<p class="HeadingRunIn"><strong>A review of the genus <em>Discomyza </em>(Diptera: Ephydridae) from Afrotropical, Australasia…
2015
Tropical Old World species of the genus Discomyza are redescribed, including male terminalia, photographs of heads and wings. One new species Discomyza fagomoga sp. nov. is described from D. R. Congo, Ethiopia, Kenya and Uganda. Two new synonyms are proposed: Discomyza obscuricornis Canzoneri and Rampini, 1996 = D. dolichocerus Cresson, 1944 and D. intermedia Canzoneri and Meneghini, 1969 = D. eritrea Cresson, 1939. A key to all species is provided. Relationships among species of Discomyza are suggested.
<p><strong>A revision of the Old World species of <em>Leptopsilopa</em> Cresson (Insecta: Diptera: Ephydridae)</strong>…
2016
Diagnoses and illustrations of three Leptopsilopa species known in the Old World: L. africana Cresson, L. mutabilis Cresson and L. pollinosa (Kertesz) are provided. Three new synonyms are proposed: L. aurata (Canzoneri and Meneghini) and L. tibialis (Canzoneri and Meneghini) = L. africana; Psilopa confeteae Canzoneri and Munari = L. pollinosa . Three other species are removed from Leptopsilopa and combined with Athyroglossa , as A. leonensis (Canzoneri and Rampini), new combination, A. mianii (Canzoneri) new combination and A. rossii (Canzoneri and Raffone), new combination.
