“…The anterior margin of the scale is lined with a rounded silicious ridge that becomes fused to and continuous with the posterior upturned rim. The pores of the base plates are generally larger in the posterior region (Wujek & Timpano 1984;Asmund & Kristiansen 1986). The surface of the scales, especially in the anterior areas, are covered with small papillae.…”

“…Scales of Mallomonas bangladeshica are very similar to those of M. peronoides except for a unique appendage on the anterior portion of the thickened ridge; this appendage is subcircular in shape and most often with umbrella-like arms (Takahashi & Hayakawa 1979;Wujek & Timpano 1984). The appendage has been referred to as a "hemi-spherical ornament" (Takahashi & Hayakawa 1979) and a "grapnel-like'' structure (Wujek & Timpano 1984), and the scales possessing it as "perfect" scales (Takahashi & Hayakawa 1979). On some scales the appendage is often more conical, smaller, and not divided into lobes, or missing; Takahashi & Hayakawa (1 979) referred to these scales as "imperfect".…”

“…In 1979 Takahashi and Hayakawa described a new variety from Bangladesh, Mallornonopsis peronoides var. bangladeshica, which was later raised to the specific level by Wujek & Timpano (1984). The third taxon, Mallonionas stellata, was described from Zimbabwe, Africa, by Cronberg (1 988), and Diirrschmidt and Cronberg reported on Mallomonas ceylanica in 1989 from Sri Lanka.…”

“…In addition to scales with an apical appendage, cells also often have a few small posterior scales that lack both the ridge structure and the apical appendage (see Fig. 8 of Wujek & Timpano 1984). Takahashi & Hayakawa ( 1979) used the presence of the anterior appendage as the primary feature for distinguishing this taxon as a new variety of M. peronoides.…”

The series Peronoides of the genus Mallomonas consists of four taxa most often reported from warm, generally tropical, climates. Recently, the taxonomic position of M. bangladeshica has been questioned, and new observations on all of the species made. The purpose of this paper was to assemble and summarize the existing literature. and report on the morphological variability of specimens of M. peronoides and M. bangladeshica found in and around the delta region of the Paraná River in Argentina. We describe several additional morphological features for each taxon. We further propose that the taxon M. bangladeshica be retained at the present time, but as a variety of M. peronoides as originally proposed by Takahashi and Hayakawa (1979).
