| Plotococcus Miller & Denno is synonymized with Leptococcus Reyne (Coccoidea: Pseudococcidae). The genus is redescribed and the adult female of the type species, L. metroxyli Reyne, is redescribed and illustrated. All species hitherto included in Plotococcus are transferred to Leptococcus as L. capixaba (Kondo) comb. nov., L. eugeniae (Miller & Denno) comb. nov., L. hambletoni (Kondo) comb. nov., L. minutus (Hempel) comb. nov., and L. neotropicus (Williams & Granara de Willink) comb. nov. A new species of Leptococcus, L. rodmani Kondo sp. n., from leaves of Guarea guidonia (Meliaceae) from Colombia, is described and illustrated based on the adult female. A revised key to adult females of all species in the genus is provided. |

| The genus Leptodoras Boulenger is a monophyletic assemblage of at least ten species distributed in large, predominantly lowland rivers throughout the northern half of cis-Andean South America. Leptodoras is diagnosed in Doradidae (thorny catfishes) by unique morphologies of the oral hood (upper labial extensions distinct with comparatively smooth ventral surface, lateral margins of extensions entire, weakly scalloped or fimbriate and without marginal papillae, and interlabial membranes of narrow or moderate width), first gill arch (enlarged accessory lamellae extend well onto medial face of gill filaments), and gas bladder (reduced size and modified cordiform shape, two distinct horn-like diverticula project from posterior walls of posterior chambers, and... |

| Abstract Background: Palyno-morphological and foliar epidermal studies plays a very important role in the correct identification and differentiation of two weeds of genus convolvulus. Objective: The aim of the study is to determine the medicinal uses of the two important weeds for correct systematic identification. Methods: Both the qualitative and quantitative features were measured with the help of Light microscopy (LM) and scanning electron microscope (SEM). Results: Variations were observed in both the weeds, i.e Convolvulus arvensis (bindweeds) and Convolvulus prostatus (soft bindweed) in epidermal cells, stomatal size and number, guard cell shape and size, subsidiary cell and diversity of trichomes. Paracytic type of stomata was found in both... |
