Diagnosis.
The color patterns, body proportions, and other features of Aleiodes bakeri are similar to those in A. nigristemmaticum (Enderlein). The most useful characters to distinguish them are the occipital carina, which is incomplete at the vertex in bakeri (Fig. 24 View Figures 21–24 ) but is complete in nigristemmaticum , and the hind wing venation, with vein M+CU being more than 2 × longer than 1M in bakeri (Fig. 23 View Figures 21–24 ), as compared with ~ 1.5 × longer in nigristemmaticum . Specimens of A. nigristemmaticum have the antenna dark brown basally, lightening toward apex, as compared with entirely honey yellow in A. bakeri (Fig. 22 View Figures 21–24 ). Three of the new species, A. angustus , A. asenjoi , and A. mabelae , also have a dorsally incomplete occipital carina. Two of these, A. angustus and A. asenjoi , are easily distinguished by having the fore wing vein 1a present (as in Fig. 1 View Figures 1, 2 ), while this vein is absent in A. bakeri (Fig. 2 View Figures 1, 2 ). Aleiodes mabelae can be distinguished by its longer fore wing second submarginal cell (Fig. 64 View Figures 64, 65 ) and the flagellum which is black at the base (Fig. 64 View Figures 64, 65 ). The second submarginal cell is comparatively shorter in A. bakeri (Figs 2 View Figures 1, 2 , 23 View Figures 21–24 ), and the flagellum is entirely the same color, yellow or orange, without being black basally (Fig. 22 View Figures 21–24 ).
Distribution.
Aleiodes bakeri is known from localities in Brazil and Peru.
Nomenclatural note.
Butcher and Quicke (2011) synonymized Hemigyroneuron Baker as a junior synonym of Aleiodes but retained Hemigyroneuron as a subgenus. The species Aleiodes (Hemigyroneuron) bakeri Butcher & Quicke, 2011 is not the same species as Aleiodes bakeri (Brues, 1912). Despite its assignment to a different subgenus, Aleiodes bakeri Butcher & Quicke, 2011 is a junior homonym of Aleiodes bakeri (Brues, 1912) and a replacement name is needed. There we hereby propose the new name, Aleiodes buntikae Shimbori & Shaw, nom. nov., for the species formerly called Aleiodes (Hemigyroneuron) bakeri Butcher & Quicke, 2011: p. 1417. The new name is a patronym in honor of Buntika Areekul-Butcher, author of the species formerly called Aleiodes (Hemigyroneuron) bakeri .
