From the Latin com mensa, meaning 'sharing a table'. In ecology, commensalism is an interaction between two living organisms, where one organism (the commensal) benefits and the other is neither harmed nor helped. As with all ecological interactions, commensalisms vary in strength and duration from intimate, long-lived symbioses to brief, weak interactions through intermediaries. An example in literature: Landau, G.D., & M.J. Gaylor, 1987. Observations on commensal Diptera (Milichiidae and Chloropidae) associated with spiders in Alabama. - Journal of Arachnology 15(2): 270-272.
This is a system for naming veins in insect wing, that was devised by John Comstock and George Needham in 1898. The system supposedly shows the homology of all insect wings.

A species that satisfies one major criterion of the scientific definition of species - it is reproductively isolated from others - but which is morphologically indistinguishable from one or more others. The group of those indistinguishable species together form a cryptic species complex. The individual species within the complex can only be separated using special techniques, like molecular genetics such as DNA barcoding.

The external skeletal structure of the insect body (dissection reveals an internal skeleton). The cuticle is secreted by the epidermis and is composed of chitin and protein. There are several differentiated layers.
Cyclorrhapha is an unranked taxon within the infraorder Muscomorpha. They are called Cyclorrhapha ('circular-seamed flies') with reference to the circular aperture through which the adult escapes the puparium. This is a circumscriptional name that has significant historical familiarity. In most classifications, this name is synonymous with the more recent 'Muscomorpha'.
I have just received the very sad news that Peter Chandler has died after a fall at home yesterday. I have no other details at the moment. We shall miss him terribly.
