Se entregan nuevos registros de Chinavia musiva que extiende su distribución en Chile a las regiones de Coquimbo en el norte y Metropolitana de Santiago hacia el sur. Se discuten los problemas de identificación existentes entre esta especie y Halyomorpha halys, y se entrega una clave pictórica para diferenciar ambos taxones.

Abstract. New records are given for the pentatomid Pellaea stictica Dallas, 1851. The new records extend the distribution of the species in Perú towards the south. The presence of the species in Chile is confirmed by the collection of new material. The first exact locality record from Paraguay is provided. Additionally, the first teratological case in this species is described. The case belongs to a right antennal oligomery with atrophy and anarthrogenesis.

The first hostplant record on Prosopis tamarugo (Fabaceae) is given for the Chilean green stink bug Chinavia chilensis. Observations were made in San Pedro de Atacama, Antofagasta Region, Chile. It was recorded that the females oviposite on the three. Later, nymphs develop on the fruits. The significance of this finding is discussed and it is concluded that C. chilensis may be highly specialized to feed on this vegetal species.
