The life cycle of Dystus puberulus Stal, including all developmental stages, is described and notes on its biology are provided. The association of this rare species of Scutelleridae with several species of Ficus is reported for first time. Nymphs and adults of this species feed on the immature fruits, which resembles them in shape and color. Nymphs and adults are densely setose, with slightly flattened antenna, characteristics that are unusual in Scutelleridae.

The life cycle of Pachycoris klugii on its native host, Cnidoscoulus multilobus (Euphorbiaceae), is reported in detail for the first time. Egg, nymphs, and adults are described and illustrated. Extensive variation was observed in the color pattern of adults. Maternal behavior was related to egg parasitism, habitat and host plant phenology. The tachinid fly Trichopoda pennipes was observed parasitizing adults and the scelionid wasp Telenomus pachycoris parasitized eggs of P. klugii.

A new species of Cholula (Myodochini) from Jamaica is described. This represents the first record of this genus for the Caribbean. Cholula minuta can be differentiated from other species of the genus mainly by its size. It is one of the smallest species described to date, being similar in size only to C. parvus, but C. minuta is unicolorous, while C. parvus has a mixture of black, brown and white coloration.

The subfamily Ischnorhynchinae is distributed worldwide and is represented by 3 genera Kleidocerys, Neokleidocerys, and Polychisme in the American Continent. Here, we report this subfamily for the first time from Costa Rica, redescribe Kleidocerys virescens, Neokleidocerys goldmani, Polychisme poecilus, and describe a new species, Kleidocerys costaricensis n. sp. A dorsal habitus illustration of the male, drawings of the male genitalia, and scanning electron micrographs of some morphological features are provided for this new species. A key to all Costa Rican species in the subfamily is presented.
