Se ofrece una lista de los isópodos peracáridos de Cuba: 57 géneros y 118 especies marinas y estuarinas, mientras que de los terrestres se presentan 47 géneros y 76 especies registradas.  Se actualiza la lista de las especies marinas y estuarinas, al tiempo que se ofrecen anotaciones sobre la ecorregión, localidad específica, sustrato y fecha de colecta de cada una. Esta ha sido preparada  con los datos compilados por los autores durante más de 45 años de colectas, separación y clasificación de estos crustáceos peracáridos. La lista de las especies terrestres se basa, principalmente, en los resultados obtenidos durante el desarrollo de las expediciones rumano-cubanas, de los años 70, publicados en revistas de limitado acceso, junto a los resultados posteriores de varios especialistas cubanos. Las ecorregiones más importantes por el número de especies citadas son la noroccidental (Norte Habana-Matanzas) y la Suroccidental (Archipiélago de los Canarreos),  mientras que en las ecorregiones Suroriental (Costa Sur de Oriente), Surcentral (Archipiélago Jardines de la Reina) y Nororiental (Costa Norte de Oriente), las citas son nulas. Los isópodos marinos cubanos más comunes son: Cirolana parva, Paracerceis caudata, Limnoria platycauda, Dynamenella perforata y Rocinela signata. El género más común en que se agrupan las especies terrestres es Pseudarmadillo, con 16 especies. Finalmente, se anexa la bibliografía cubana sobre el grupo no citada en el texto.

The gregarious behaviour of juveniles (16-45 mm CL) of the spiny lobster, Panulirus argus in artificial shelters (concrete blocks), was studied in a nursery area in the southwestern region of Cuba. The average size of the juveniles was significantly different (df = 3; F = 796.60; P < 0.001) among the periods analysed (1982( -19841986-19881989-1991 and 1992-1994, average = 39.46 mm CL) but it was not between sexes (df = 1; F = 0.3640 ns; P = 0.55). The proportion of males and females did not differ significantly from 1 : 1 in sizes between 20 and 50 mm (CL). The sexes could be distinguished at a size of 16-20 mm (CL) and this was also the size-class that emerged from settlement places and adopted gregarious behaviour. As the source of immigrants to the nursery area was from the south, the southern shelters, located approximately 17 km from the barrier reef, were the first to be colonized. The highly significant relationship between the abundance of juveniles and pre-recruits (N = 13, R 2 = 0.8314, P < 0.001), suggests that the variations in abundance of the recruitment observed are displayed in all nursery areas. The high densities of lobster juveniles in nursery areas, their gregarious behaviour, their territorial migratory habits, and the evident decrease of recruitment to nursery areas in the Gulf of Batabanó from 1988 onwards, suggest that introduction of artificial shelters might help diminish natural mortality of post-pueruli and juveniles in these phases and increase recruitment to fishing areas.

Se presenta un recuento histórico sobre las investigaciones previas desarrolladas sobre los cumáceos cubanos. Además, se ofrecen los caracteres diagnósticos para reconocer las cuatro familias representadas en Cuba: Bodotriidae (Cyclaspis y Vaunthompsonia); Diastylidae (Leptostylis y Oxyurostylis); Leuconidae (Leucon) y Nannastacidae (Campylaspis, Cubanocuma, Cumella y Elassocumella). Un total de 27 especies registradas para el país podrán ser clasificadas mediante las claves dicotómicas que se ofrecen en este trabajo. También se presenta una diagnosis para cada familia y género, así como una figura para cada especie.

Cubadeutella cavernicola new genus, new species, is described based on specimens collected from a cave of southern Cuba, Caribbean Sea. Cubadeutella new genus is close to Deutella, but presents a higher number of plesiomorphic characters: the number of articles in antenna 1 is higher in Cubadeutella (20-22) than in Deutella (7-14); the flagellum of antenna 2 in Cubadeutella is 4 -articulate while it is 2-articulate in Deutella and the pereopods 3 and 4 are 4-articulate in Cubadeutella and 1 or 2-articulate in Deutella. Cubadeutella, together with Triantella and Protellina are the only genera in the Caprellinae with the flagellum of antennae 2 more than 2-articulate, and the presence of 4-articulate pereopod 3 and 4 is unique in the Caprellidae.

Se describe una especie nueva de anfípodo del género Photis colectada en las aguas de la Región Oriental del archipiélago cubano. Se presentan las diferencias más notables de dicha especie con las dos más semejantes presentes en el área: Photis sp. F (LeCroy, 2000) y P. sarae Souza-Filho y Serejo, 2010. Es la tercera especie del género registrada en las aguas cubanas.

Investigations to study the long and complex larval cycle of the spiny lobster, Panulirus argus in artificial shelters, on the barrier reef and in sea grass meadows, became efficient programs for catching large numbers of pueruli and juveniles at some locations of the Cuban archipelago. These data support a study to obtain a better understanding of the recruitment variability, of the mortality rates during the juvenile phase, and to evaluate the potential alternative for growout of pueruli and juveniles to marketable sizes. The intensity of larval recruitment is much higher in the area close to the edge of the shelf (32.2 pueruli/collector) and diminishes toward the shallow coastal waters (1.2 pueruli/collector). seaweed collectors, there is an absence of predators and diseases, a good level of food (a high variety of invertebrates, fish eggs and fish larvae, Foraminifera, and filamentous algae), and a gregarious behaviour in a structurally complex tassel may increase individual growth rates. The natural mortality rate in the juvenile nursery area has been estimated at 0.42 year −1 , so that 58% was estimated to survive and be recruited to the fishery. The results of our studies indicate that juvenile removals from the wild have a negative impact on pre-recruits and subsequent catches. Improvement of the techniques to collect pueruli is needed to catch a large number of these, because the current objective of the program in Cuba is to measure puerulus recruitment and to predict catches. Any strategy of commercial investment for the growout of pueruli and post-pueruli to marketable sizes requires accurate seasonal catch-and-effort data, and knowledge of the population parameters, all needed to assist in preventing overfishing.
