Duda, 1930 : 74 Sabrosky and Paganelli, 1984 : 5 Systematics of Agrophaspidium, a new genus of Neotropical Chloropidae (Diptera) Wheeler, Terry A. Mlynarek, Julia J. Zootaxa 2008 1926 41 52 Duda Duda [151,568,1336,1362] Insecta Chloropidae Agrophaspidium Animalia Diptera 3 44 Arthropoda species hastatum comb. nov.     Dactylothyrea hastata  Duda, 1930: 74.    Acanthopeltastes hastatus:  Sabrosky and Paganelli, 1984: 5.    Typematerial: HolotypeΨ: COSTA RICA: La Suizade Turrialba ( HNHM, not examined, see Remarks).   Remarks:We did not examine the female holotypeof  D. hastata. Our interpretation of the species is based on extensive notes and illustrations of the holotypemade at HNHM by C.W. Sabrosky in 1938, 1960 and 1975.  Duda (1930)assigned most Neotropical species with scutellar projections to  Dactylothyreade Meijere, an Old World oscinelline genus that is not closely related to  Agrophaspidium. Sabrosky and Paganelli (1984)transferred  D. hastata, along with other Neotropical species then assigned to  Dactylothyrea, to the Neotropical genus  AcanthopeltastesEnderlein. Althoughspecies of that genus also have scutellar projections,  Acanthopeltastesspecies have several synapomorphic character states not found in  D. hastata. This species belongs to  Agrophaspidiumbased on the structure of the scutellum, the wing venation and the absence of most defining apomorphies of  Acanthopeltastes. However, the holotypeis female and, as such, it is impossible to associate the name with one of the other known species. The leg colour and thoracic structure correspond most closely to those of  A. psilotum, but the frontal triangle is entirely polished (anterior apex pollinose in male  A. psilotum) and the palpus is dark (yellow in male  A. psilotum). In the absence of additional evidence, we cannot be certain whether this represents sexual dimorphism or species-level differences.
