New Genus And Species

A new genus and species, Oreadomyia albertae, is described from the mountains of western Alberta. This differs in several important adult characters from the three previously known genera and species of Nymphomyiidae, particularly in the possession of mouthparts (which are rather unlike those of other Diptera), in the form of the compound eyes, and in the virtually apterous condition. It is placed in a new subfamily, Oreadomyiinae. Further records of Palaeodipteron walkeri Ide are given for New Brunswick. These include examples of the previously unknown, fully alate adults. The systematic position of the Nymphomyioidea is briefly discussed. The group is retained in a separate suborder, Archaeodiptera. An appendix gives a list of arthropods trapped at the same site as O. albertae.

Diagnostic Characters

A new genus and species of Keroplatidae (Diptera), Langkawiana maculata gen. et sp.n., is described and its systematic position is discussed. The description is based on a male collected at Langkawi Island (Malaysia). Diagnostic characters of the new genus are as follows: the absence of ocelli, membraneous area around cerebral sclerite continues behind compound eyes, both orbital sclerite and frons well developed, short palpomeres, wings with dark bands, relatively long radio-median fusion, tibial trichia arranged in regular rows, reduced spurs on mid and hind tibia, and details on male terminalia. A new phylogenetic analysis of the tribe Robsonomyiini is proposed and a key to genera is presented.

A new genus and species of calanoid copepods belonging to the group of Bradfordian families, Pogonura rugosagen. et sp. nov., is described from the deep-sea hyperbenthic layers off Nagannu Island, Okinawa Prefecture, southwestern Japan. Pogonuragen. nov. is similar to another Bradfordian genus Procenognatha in sharing the following characteristics: (1) segmentation of the antennule, fused segments II–IV, X–XI, XXVII–XXVIII in females and II–IV, X–XII, XXVII–XXVIII, right XXII–XXIII in males; (2) retained setae on the ancestral segments I–IV of the antennary exopod; (3) setules on the mandibular gnathobase; (4) 3 sclerotized setae on the maxillary endopod; (5) absence of sensory seta on the maxilliped; (6) large spinules on the posterior surface of the rami of legs 2 and 3; and (7) setation and segmentation of female leg 5. Pogonuragen. nov. is distinctly distinguished from Procenognatha by the following features: (1) reduction of a seta on the ancestral segment IX of the antennary exopod, (2) 8 setae (7 in Procenognatha) on the maxillular exopod, (3) 5 brush-like setae (6 in Procenognatha) on the maxillary endopod, and (4) reduction of right endopod of male leg 5. The systematic position of Pogonuragen. nov. in the Bradfordian families is also discussed. Although this new genus shares synapomorphies with some diaixid genera, an assignment of this genus to any Bradfordian family should be pending until the taxonomy of this family group is clearly settled.

Ne Spain

The new genus Iberostomata (Bryozoa, Ptilodictyina) from the Cystoid Limestone Formation in the Iberian Chains (NE Spain) is here described and its phylogenetic relationships analyzed using cladistic methods. Twenty-eight identifying characters used in traditional systematics have been codified for nine ptilodictyine families, two timanodictyine families and 34 ptilodictyine genera. The results obtained in this analysis place the new genus Iberostomata and the genus Stellatodictya, traditionally included in the family Ptilodictyidae, in the family Rhinidictyidae, question the validity of the family Intraporidae, question the assignment of Amurodictya and Astrovidictya to the family Stictoporellidae, as well as the assignment of the genera Junggarotrypa, Goniotrypa, and Prophyllodictya to the family Rhinidictyidae, and place the family Phragmopheridae in a uncertain systematic position.

A New Species

A new genus and species belonging to the primary freshwater crab family Potamidae, and a new species of the genus Artopotamon Dai & Chen, 1985, are described on the basis of remarkable G1and female gonopore characters. Semicirculara lincangensis gen. & sp. nov. and Artopotamon latopeos sp. nov. were collected from southwestern and northwestern Yunnan Province, China, respectively. All type specimens are deposited in Nanjing Normal University in Nanjing and the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing. Mitochondrial molecular data, from the partial sequence of the mitochondrial 16S rRNA gene, are also shown to support the distinct systematic position of the new taxa.

Susamyia Ziegler & Gilasian gen. nov. and its type species Susamyia mira Ziegler & Gilasian gen. et sp. nov. are described from southwestern Karkheh National Park and southeastern Jazmourian Wetland of Iran. Drawings of terminalia and head of the male as well as images of habitus, head and egg are provided. Susamyia gen. nov. is incorporated into the identification key to the Palearctic tachinid genera of Tschorsnig & Richter (1998). The systematic position of Susamyia gen. nov. in the tribe Goniini (Exoristinae) is discussed in light of molecular analyses based on the ribosomal genes 16S, 18S and 28S, and the egg type of females. The morphology of the microtype eggs was studied and compared with that of other Goniini, but proved too unreliable to be included in the phylogenetic analysis. Susamyia gen. nov. is believed to be most closely related to the goniine genera Gymnophryxe Villeneuve, 1922, Palesisa Villeneuve, 1929 and Prosopodopsis Townsend, 1926.

History Of

The literature on the two described species of Nymphomyiidae, Nymphomyia alba Tokunaga and Palaeodipteron walkeri Ide, is reviewed. Previous opinions on the systematic position of the family and what is known or surmised about their biology are outlined. The occurrence of P. walkeri in Canada is discussed and new records are given from a small upland stream in western Quebec. The larvae of Nymphomyiidae were previously unknown, but those of P. walkeri have been discovered. It is confirmed that they are aquatic. Details of habitat of P. walkeri are given, and the larva is described and figured in detail. An outline of the probable bivoltine life history of this species and some further considerations regarding the relationships of the Nymphomyiidae are also made. An appendix makes additional comments on P. walkeri adults and the opportunity is taken by the second author to describe a new genus and species, Felicitomyia brundini, from the eastern Himalaya.
