“…Diopsinae are further subdivided into two tribes, the basal Sphyracephailini and the more-derived Diopsini. (4,5,(17)(18)(19) Diopsinae are a large and diverse group with huge interspecific and intraspecific variation in hypercephaly (Fig. 2).…”

“…(4) There are estimated to be approximately 160 stalk-eyed fly species currently assigned to 11 genera although the phylogeny is incomplete and new species continue to be described. (5,19,20) Some genera contain over 40 species (Diasemopsis and Diopsis) whereas some only contain a few members (Eurydiopsis). (18,21) Almost all diopsid species are found in the Old World tropics although species have also been found in Neartctic and Palaearctic regions as well as Europe.…”

“…Monomorphic species, although rarer, also occur in all genera. (4,18) Recent studies of diopsid phylogeny based on DNA (4,5) and morphological data (17,19) agree that dimorphism has been lost and gained on several occasions, although there is some debate over whether dimorphism or monomorphism is the ancestral state, as the basal Sphyracephalini tribe includes both dimorphic and monomorphic species. (4,5,18) Of more practical relevance is the undisputed fact that closely related species show large differences in degree of dimorphism.…”

Stalk-eyed flies of the family Diopsidae exhibit a unique form of hypercephaly, which has evolved under both natural and sexual selection. Male hypercephaly is used by female diopsids as an indicator of male quality. By choosing to mate with males expressing the most-exaggerated hypercephaly, females can benefit both from the enhanced fertility of these males and the transmission of other heritable advantages to their offspring. Stalk-eyed flies are close relatives of the model organism, Drosophila melanogaster. We have shown that similar genetic and cellular mechanisms regulate the initial development of the head capsule in fruitflies and diopsids. The great diversity of stalk-eyed fly species, exhibiting varying degrees of hypercephaly and sexual dimorphism, constitutes a major advantage for comparative studies of their development and evolution.

“…However, after an early phylogenetic hypothesis on generic level by Shillito (1971), which was based on the evaluation of only 13 morphological characters, there was not much progress in this fi eld until the turn of the century. Th ere then followed a number of modern phylogenetic analyses, based on DNA Carr et al 2006 ;Kotrba & Balke 2006 ;Marshall et al 2009 ) and/or morphological data (Meier & Hilger 2000 ;Meier & Baker 2002 ;Kotrba 2004 ). Th ese analyses resulted in a now well-established phylogenetic hypothesis (e.g., Kotrba & Balke 2006 ), covering 8 of the 11 diopsid genera known today.…”

Th e placement of Diopsina in a monophyletic clade with Diopsis and Eurydiopsis is confi rmed and a sister group relationship between Diopsina and Diopsis recovered with moderate support. Th e clarifi cation of the phylogenetic position of Diopsina nested deeply within Diopsini is of crucial importance for the understanding of the relationships and the evolution of various morphological characters within the family.

Among insects, males have evolved the ability to discriminate potential mates to avoid vain mating attempts. In Diptera, courtship and mating behaviors of species that do not discriminate potential mates have rarely been studied. In this study, we investigated copulation attempts of the stalk-eyed fly, Sphyracephala detrahens males, which do not engage in any observable pre-copulatory courtship behavior. We found that sexually mature males attempted to copulate with mature males and immature adults of both sexes, as frequently as with mature females. Successful copulation only occurred with mature females. Immature females rejected mounting males by vibrating their bodies and immature and mature males by incurving their abdomen downward. Comparison of the cuticular hydrocarbon components of individuals of different sexes and maturity levels indicated that the cuticular hydrocarbon profiles were similar regardless of the sex and sexual maturity. Therefore, we suggest that visual or chemical information are of little use for males S. detrahens in discriminating receptive conspecific mates. Since elaborate mate discrimination behaviors lead to additional time and energy costs when discrimination is difficult, S. detrahens may increase reproductive success simply by increasing the number of copulation attempts.
