| Glochinema bathyperuvensis sp. n., the first record of Epsilonematidae from bathyal muddy sediments of the oxygen minimum zone (OMZ) off Callao, Peru (eastern Pacific Ocean) is described. The new species belongs to the subfamily Glochinematinae and is characterized by the possession of more than 8 pairs of subdorsal thorns asymmetrically arranged and a single dorsal one in the pharyngeal region, as well as by the presence of ten to thirteen blade-like cuticular protrusions forming a latero-dorsal palisade around the posterior head region and anterior cervical region. In addition, G. bathyperuvensis is characterized by its large size, more than 240 cuticular annules, provided with an extremely dense „hairy“ body ornamentation and, four rows of ambulatory... |

| A large amount of unidentified material of the Neotropical genus Guatteria (Annonaceae) is lying on herbarium shelves around the world. Here twelve species are described in an attempt to reduce this amount of unidentified material. Next to this, previously unidentified material is now assigned to G. asplundiana, G. microcarpa, G. pastazae, and G. scalarinervia, four previously described but poorly known species, thus providing a clearer circumscription of these species. Furthermore, G. discolor and G. megalophylla appear to have a wider distribution than previously thought. Lastly, G. macrantha, a curious species only known from the type, is excluded from the genus and referred to Uvaria. With the description of twelve new species and the synonymizing of... |

| The recent finding of a private shell collection from Peru, dating from the early 20th century, sheds some new light on the history of Neotropical malacology. The collection of J.J. Bravo is partly reconstructed and some data is given on his life and conchological activities. It shows that, in the early 20th century, connections did exist between amateur conchologists from Peru, the United Kingdom and the United States of America. El reciente hallazgo de los restos de una colección privada de moluscos en el Perú, echa algunas luces sobre la Malacología Neotropical. Debido a esto, ahora podemos reconstruir parcialmente, la colección de J.J. Bravo, y aportar datos sobre su vida y actividades malacológicas. Todo indica que a comienzos del siglo XX, ya... |

| Croton maasii, a new species from South America, is described and illustrated. The species is only known from terra firme forests of the extreme western Amazonian region, in W Brazil and adjacent E Peru. Croton maasii resembles C. pachypodus, a more abundant and widely distributed species in the Neotropics, but differs from it in its much smaller fruits, foliage colour, less dense leaf indumentum, and a more even position of the petiolar glands. |

| The family Orthalicidae is well represented in Peru but, like in other families, some species are wellknown and others have not been reported on since their original descriptions. In this paper we present new records for well-known species and elucidate the status of several lesser known taxa. Four taxa are described as new: Bostryx chusgonensis sipas, B. fragilis, Scutalus (Scutalus) mariopenai and S. (S.) phaeocheilus altoensis. The following species are recorded as new to the Peruvian malacofauna: Corona pfeifferi, Drymaeus (D.) branneri, and Thaumastus flori. Strophocheilus tenuis Haas, 1955 is now considered synonymous with Thaumastus (Paeniscutalus) crenellus (Philippi, 1867). Plekocheilus conspicuus Pilsbry, 1932 is now placed in the synonymy of... |
