This work represents the first record of the genus from Paraguay. A complete description, ecological comments, illustrations in optical and scanning electron microscopy, and a distribution map are presented.Key words: Barbula uncinicoma; Boquerón; Gertrudiella validinervis; hyalodermisIn the course of a study of the bryological flora of Paraguay (Flores et al. 2015), some samples were found to perfectly match the description of Gertrudiella uncinicoma (Müll.Hal.) G.M.Suárez & Schiavone (Suárez & Schiavone 2010). This genus and species were not recorded previously from the country (O’Shea & Price 2008).This species was first described by Müller (1879) as Barbula uncinicoma Müll.Hal. from samples collected in Córdoba, central Argentina. Later, this taxon was transferred to Gertrudiella (Suárez & Schiavone 2010), a unispecific genus described by Brotherus (1925) to accommodate a single species (G. validinervis) from Bolivia.The aim of this work is to report for the first time the presence of this genus and species in Paraguay. A complete description, ecological comments, photomicrographs, and a distribution map are presented.We studied samples collected in Paraguay and other specimens deposited in Instituto de Botánica del Nordeste (CTES), University of Helsinki (H), Friedrich-Schiller-Universität Jena (JE), Naturalis (L), and Fundación Miguel Lillo (LIL). The specimens were analyzed morphologically using conventional techniques for bryophytes and mount-ed in Hoyer’s solution (Anderson 1954).Microscopic characters were analyzed by using light microscopy (LM) with a Leica Model CME, and scanning electron microscopy (SEM) with JEOL 5800 LV oper-ating at 20 KV. The SEM images were obtained from samples mounted on double-sided tape and coated with gold-palladium.Examined material. Paraguay.

Gertrudiella uncini-coma is commonly found forming dense cushion on soil, sometimes associated with extensive mats of Selaginella sp. and in disturbed areas. It is a Neotropical species (Figure 12), known to date from Argentina, Bolivia, Chile and Peru. This work represents the first record of the genus from Paraguay, extending the distribution area of the species and adding information about the bryological diversity of the country.For further synonyms, descriptions and illustrations, see Schiavone & Suárez (2003), Suárez & Schiavone (2010), and Zander (1993).As a result of recent collecting expeditions to Para-guay, some specimens collected exhibit in all diagnostic characters of Gertrudiella uncinicoma. These results allow us to confirm for the first time the presence of the genus in the country. Gertrudiella uncinicoma is characterized by the presence of a strong central strand on the stem, a well-developed hyalodermis composed of thick-walled cells, acute leaves with a sheathing base, laminal cells mammil-lose on the ventral surface, plane to the dorsal, and more than 6 guide cells distributed in 3 or 4 rows in transverse section of the costae. This first record of the genus in Para-guay increases the range of distribution, and proves that it is wider than previously supposed.ACKNOWLEDGEMENTSThanks are owed to the curators of the herbaria for making the specimens available for examination and to Secretaría del Ambiente de Paraguay (SEAM).
