Abstract

This paper deals with the Trinidad Tachinids (Diptera) of the group of genera assembled by L. P. Mesnil (1939) as the tribe Winthemiini, of which the type genus is Winthemia R.-D. The group was subsequently recognized by F. I. van Emden (1954) and later by B. Herring (1960) but has not, so far as I am aware, been considered as a taxonomic unit in relation to the tachinids of the Americas. It is simply a relatively small section of the vast mass of genera called by Mesnil (1939, 1944) the Salmaciinae, or as we now say, the Goniinae, defined by the possession of a bristled prosternum, reclinate posterior frontals, a first post-sutural supraalar as strong as or stronger than, the first postdorsocentral, an absence of infrasquamal setulae, a second abdominal segment excavated to the posterior border and a short robust form. From the other Goniinae, the Winthemiini are separated mainly by the hairy “barrette”, the pattern of the humeral bristles and the reproductive habit of depositing large plano-convex undeveloped eggs on the body of the host insect, the ovipositor having the form of a membranous tube, retractile and of moderate length, reinforced by some elongate sclerites.

In the present paper, in addition to the well-known Winthemia and Nemorilla, the genera Hemisturmia and Triodontopyga have been included. The genitalia of all the Trinidad species have been studied. Their structure appears, on the whole, to reinforce the taxonomic status of the group but whether it will survive a more extensive survey of tachinid genera, remains to be seen.Seven species are described as new.
