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.
