Bakerius marmoratus (Hempel)   comb. nov.

Aleurodicus marmoratus Hempel, 1922b: 1124   (Portuguese), 1161 (English). Syntypes (adults), Brazil [MZUSP, examined].

DISTRIBUTION. Neotropical Region – Brazil.

MATERIAL EXAMINED. Adult syntypes – see details and discussion below.

COMMENTS. In connection with an earlier study ( Martin, 2004) the author was sent a syntypic slide of A. marmoratus   on loan, through the kindness of MZUSP. This slide comprised only adult specimens, but no puparia could be located (Sonia Casari, MZUSP, personal communication). With our currently limited understanding of the taxonomy of adult whiteflies, puparia would be necessary for any definitive assessment of this species. However, some conclusions can be drawn from the original description, as discussed below.

Hempel’s description of the “larva” of marmoratus   details three pairs of large circular compound glands [compound pores], one pair cephalically and two pairs abdominally, which strongly suggests a puparium of Bakerius   ( Fig. 115 View FIGURES 114–116 ) or Leonardius   [third-instar nymphs of Aleurodicus species   possess just two pairs of compound pores]. The “pupa” [puparium] is described as having the median area distinctly darker than the periphery, another typical character for Bakerius   puparia. The description continues to detail six (not six pairs of) white wax tubes [filaments] produced by the compound pores. Hempel also stated that compound pores were not present in “very young” nymphs, whereas they are present in 2 nd and 3 rd nymphal instars of Aleurodicus species.   However, nymphal compound pores are not present in Bakerius species.  

It is therefore concluded that marmoratus   is best placed in Bakerius   (comb. nov.), in the absence of any descriptive suggestion of the additional presence of agglomerate pores, that would then indicate inclusion in Leonardius   instead.
