The new species, Xenylla gwiazdowiczi sp. nov., can be distinguished from previously described Xenylla species by combination of the following characters mucro separated from dens, presence of complete row of setae c on dorsal side of the head, four thick sensilla on antennal segment IV, 19,19,18 setae on tibiotarsi of legs I-III, slightly serrated setae on abdominal segments V-VI, presence of two weakly clavate tenent hairs on each leg. The new species resembles X. spinosissima Najt Rubio, 1978 and X. humicola (Fabricius, 1780). Similarities between them have been discussed. An identification key to Neotropical species of the genus is provided.A new species of the pilumnid crab genus Pilumnus Leach, 1815, P. mantelattoi n. sp., is described and illustrated on the basis of a single ovigerous female specimen from Belize, bordering the northwestern Caribbean Sea. The holotype, an ovigerous female, was taken from an epifaunal accumulation of sponges, ascidians, and hydroids on red mangrove roots suspended in the water column. Superficially resembling Pilumnus floridanus Stimpson, 1871, with which it occurs sympatrically, it is distinguished from this and all other known western Atlantic species on the basis of both morphology and molecular markers.The tribe Mecistoscelini of the subfamily Mirinae (Insecta, Heteroptera Miridae) from India is reviewed. Three genera and six species are cited from the country and are keyed, illustrated and diagnosed. Mystilus manipurensis n. sp. is described from Manipur.
