AbstractIn a creek northwest of the Gatineau Hills (Quebec) larvae of Chironomidae (Diptera) were found living in phoretic association with the immature stages of Perlidae (Plecoptera). The larvae were reared to the adult stage in the laboratory. Life pattern and morphological comparisons are made with other phoretic and parasitic forms of Orthocladiinae and with certain other genera, and it is concluded that the form represents a new genus and species of Orthocladiini, and has probably originated from the common ancestors of the genera Rheocricotopus, Paracricotopus and Microcricotopus. Detailed descriptions are given of the imago, pupa and larva of this insect.

AbstractA new genus and species, Sinuothrips hasta, is described from Phragmites imported into England from Turkey. It is similar in most character states to the common genus Haplothrips, but with the tergites bearing a transverse row of discal setae and the head a large dorsal projection.

Burmese Amber

A new genus and species of scale insect (Hemiptera: Coccomorpha) is described from a female specimen in mid-Cretaceous Burmese (Myanmar) amber. Fossil female scales are rare and the present species, described as Paleolepidotus macrocolus gen. et sp. n., has such an unusual assortment of morphological features that it could not be assigned to any particular extant or extinct family. The small, ferruginous specimen exhibits a series of long wax pencils that extend around the body, including the head. The antennae and legs are quite long compared to other extant and extinct scale fossils. Of special interest are the protruding eyes, and a conical-triangular rostrum arising from between the forelegs; the claws with bifid apices are also unique. The ovisac contains immature stages.

Keys are given to the genera of the Helosciomyzinae and the Australian species of Helosciomyza Hendel. The following new species are described by Steyskal: Helosciomyza anaxantha, H. anhecta, H. australica, H. luteipennis and H. macalpinei. A new genus and species, Eurotocus australis, is also described by Steyskal. The first data concerning immature stages in the subfamily are given by Knutson in the form of detailed descriptions of the puparia and associated larval structures of Eurotocus australis and Helosciomyza australica, and the egg of H. ferruginea is described by Steyskal.

Caudal Rami

A new genus and species of Normanellidae (Copepoda, Harpacticoida), Paranaiara inajae gen. et sp. nov., is described from the continental shelf off the northern coast of São Paulo State, Brazil. The new genus differs from the type genus Normanella Brady, 1880 and Sagamiella Lee & Huys, 1999 in its presence of lamelliform caudal rami, a maxillulary endopod represented by 2 setae, an unarmed maxillipedal syncoxa, and reduced setation on P2 enp-2 (without outer spine) and P3 enp-2 (with only 2 inner setae). All these apomorphic character states are shared with the genus Pseudocletodes Scott & Scott, 1893, formerly placed in the family Nannopodidae (ex Huntemanniidae) and here assigned to the Normanellidae. Pseudocletodes can be differentiated from Paranaiara by the loss of the P1 endopod and of the inner seta on P2–P4 enp-1, the presence of only 2 inner setae on P2 enp-2 (instead of 3) and only 1 inner seta on P4 exp-3 (instead of 2), the presence of a second inner seta on P4 enp-2 (instead of 1), the morphology of the fifth pair of legs which are not medially fused and have only 3 endopodal elements (instead of 4) in the male, and the well developed caudal ramus seta V (instead of rudimentary). It is postulated that prehensility of the P1 endopod was secondarily lost in the common ancestor of Paranaiara and Pseudocletodes. An updated family diagnosis of the Normanellidae and a dichotomous identification key to the 22 currently valid species are presented.

Upper Volta

A new genus and species of mermithid nematode parasitizing adult females of Anopheles funestus (Giles) in Upper Volta is described. The new genus Empidomermis is characterized by having six head papillae, eight hypodermal cords, cuticle without noticeable cross fibers, two short slightly curved spicules (equal to or less than body width at cloaca), a relatively short S-shaped vagina, small amphids, and postparasitic juveniles with a well-developed tail appendage.The nematodes could only be successfully reared to maturity if the hosts were held on glucose 3–4 days after the blood meal. Postparasitic juvenile mermithids molted to the adult stage about 17 days after leaving their mosquito hosts and mating and oviposition occurred immediately afterwards. The eggs hatched about 54 days after oviposition when mosquito larvae were added to the container. Parasitized adult female A. funestus were sterilized and died soon after the nematodes emerged.

A new palaeodictyopterid, Aviobreyeria gracilis gen.n., sp.n., is described from an outcrop of Upper Carboniferous (Westphalian C/D) deposits at Avion in the Nord-Pas-de-Calais department (France). This new taxon is placed in the family Breyeriidae based on a comparison of the pattern of venation in its forewing venation with that of other breyeriids and possibly related genera within the Breyerioidea. In addition, wings of different immature instars of palaeodictyopterids from the same strata with a similar pattern of venation but differing in having an enlarged RP and a broader anal area (supposed hind wings) were also tentatively attributed to Breyeriidae gen. et sp. indet.. These wings have a roughly identifiable venation and exhibit the gradual development of wings through different ontogenetic stages and their position on the thorax, which is sparsely documented for Paleozoic insects. Discovery of immature and adult stages of palaeodictyopterids in the same layers also indicates they lived in similar habitats.

A New Species

A new genus and species of the subfamily Cossoninae, Omanocossonus sabulosus gen. et sp. nov. is described from Oman. All specimens including larvae were found on sand dunes on the seashore in roots of Calotropis procera (Aiton) W.T. Aiton. The crucial features, including male and female terminalia, are illustrated, and the taxonomic position of the new genus within Cossoninae is briefly discussed. The generic status of Lindbergius Roudier, 1957 is resurrected. The mature larva of the new species is described, larval morphology is discussed and the current state of knowledge about immature stages of Cossoninae is summarized.
