Copulation reduces male but not female longevity in Saltella sphondylli (Diptera: Sepsidae)

Mating more than once is extremely costly for females in many species, making the near ubiquity of polyandry difficult to understand. However, evidence of mating costs for males is much rarer. We investigated the effects of copulation on longevity of male and female flies (Saltella sphondylli). We also scrutinized potential fecundity and fertility benefits to females with differing mating history. Copulation per se was found to decrease the longevity of males but not that of females. However, when females were allowed to lay eggs, females that mated died earlier than virgin females, indicating costs of egg production and/or oviposition. Thus, although longevity costs of copulation are higher for males, reproduction is nevertheless costly for females. We also found no differences in fecundity or fertility relative to female mating history. Results suggest that polyandry may be driven by minor costs rather than by major benefits in this species.

The First Mitochondrial Genome of the Sepsid Fly Nemopoda mamaevi Ozerov, 1997 (Diptera: Sciomyzoidea: Sepsidae), with Mitochondrial Genome Phylogeny of Cyclorrhapha

Sepsid flies (Diptera: Sepsidae) are important model insects for sexual selection research. In order to develop mitochondrial (mt) genome data for this significant group, we sequenced the first complete mt genome of the sepsid fly Nemopoda mamaevi Ozerov, 1997. The circular 15,878 bp mt genome is typical of Diptera, containing all 37 genes usually present in bilaterian animals. We discovered inaccurate annotations of fly mt genomes previously deposited on GenBank and thus re-annotated all published mt genomes of Cyclorrhapha. These re-annotations were based on comparative analysis of homologous genes, and provide a statistical analysis of start and stop codon positions. We further detected two 18 bp of conserved intergenic sequences from tRNA^Glu-tRNA^Phe and ND1-tRNA^Ser(UCN) across Cyclorrhapha, which are the mtTERM binding site motifs. Additionally, we compared automated annotation software MITOS with hand annotation method. Phylogenetic trees based on the mt genome data from Cyclorrhapha were inferred by Maximum-likelihood and Bayesian methods, strongly supported a close relationship between Sepsidae and the Tephritoidea.     

The distribution and biology of Sepsidae (Diptera) in upland regions of northern England

Abstract. 1. A survey of the distribution of Sepsidae was made over 2 years at forty-two sites in northern England. Material was collected by pitfall trapping and in sweep-net samples.
2. With the exception of a single specimen taken in a pasture, only members of the genus Sepsis were found and three species, S.cynipsea, S.orthocnemis and S.neocynipsea , occurred at most sites. The numbers of S.cynipsea were greater than S.orthocnemis at the great majority of sites. S.neocynipsea was the least abundant of the three species but occurred over the whole altitudinal range and formed a greater proportion of the catch at higher sites.
3. It is suggested that the three commonest species use sheep dung as their main larval habitat in upland areas. Cow dung (the commonest reported larval habitat of Sepsis spp.) did not occur on any of the main sites studied. No sepsids were reared from red grouse droppings.
4. There was no difference in the species composition on peat and grassland sites but almost 4 times as many sepsids were caught on the peat moor than on the neighbouring grasslands.
5. There was a marked bimodal distribution of adults with a trough of captures in June and July. This is in contrast to data from other studies, at low altitudes, and is probably the result of there being only two generations per year in upland areas rather than four (or more) in warmer conditions.

Cladistic analysis of the Sepsidae (Cyclorrhapha: Diptera) based on a comparative scanning electron microscopic study of larvae

The result of a phylogenetic analysis of the Sepsidae based on larval characters is presented. It is shown that cyclorrhaphan larvae can be as rich a source of characters as Nematocera immatures when investigated using an SEM. The cladistic analysis comprised fifty-two species in sixteen genera of the Sepsidae and five outgroup species and used fifty-seven morphological characters. It found seven parsimonious trees which only differed with respect to the arrangement of some species within the genus Themira. The basal dichotomies of the phylogenetic trees are particularly well supported, indicating the conservative nature of larval characters. Orygma is confirmed as the sister group of all the remaining sepsids, the Sepsinae. There is good larval evidence that Ortalischema is the sister group of all remaining Sepsinae and that the Toxopodinae constitute an early radiation within the Sepsidae. According to larval data, some genera are paraphyletic ( Themira, Palaeosepsis ), but adult characters appear to contradict these findings. Among the traditionally recognized higher taxa within the Sepsidae, Hennig's Themira species-group and Steysbal's Sepsini have to be rejected as polyphyletic. However, Hennig's Sepsis species-group is confirmed as monophyletic and will probably constitute one major element of a future phylogenetic system of the Sepsidae. States of the strongly modified fore-legs of some adult sepsid males are mapped onto the phylogenetic tree, largely confirming Šulc's ideas about the evolution of these features. The origin and evolution of male sternites with brushes and a gland on the tibiae of the males ('osmeterium') are discussed. Whereas adult characters point to a sister-group relationship between the Sepsidae and the Ropalomeridae, larval characters appear to indicate a sister-group relationship between the Coelopidae and the Sepsidae. The evidence for both hypotheses is critically evaluated.     

Review of the systematics and phylogenetic relationships of the Sabethini (Diptera: Culicidae)

This paper reviews the historical treatment of the tribe Sabethini and genus-group taxa and examines the unusual life histories associated with the group. Although recognized by taxonomists as distinct, the taxonomic position of sabethines has been questioned and their rank within the family Culicidae unstable. In order to evaluate the current status of the classification of the tribe a cladistic analysis is performed. Thirty-seven taxa are selected from within the Sabethini and two outgroups were chosen from the tribe Aedini. Exemplars are selected from genus-group taxa world-wide and new and traditional character systems examined in larval, pupal and adult life stages. The results firmly establish the sabethines as a monophyletic group. However, the genera Runchomyia , Tripteroides and Wyeomyia are not demonstrably monophyletic. In addition, the data support the New World taxa as a monophyletic group to a paraphyletic assemblage of Old World taxa. The pattern displayed by the cladogram suggests the ability to vector arboviruses has arisen more than once in mosquitoes.
