This work presents accounts and illustrations of the lady beetle species reported from Puerto Rico. Fifty-three species are discussed, including rare and uncommon lady beetles occurring on the Puerto Rican archipelago. The work also includes keys for subfamilies and species, the description of a new species (Zilus barbosi sp. nov.), and a redescription of Diomus ochroderus (Mulsant). Brief accounts of the history of coccinellid collections and collectors, and of classical bio-control efforts in Puerto Rico are given, including an annotated list of 24 historical biological control introductions.

Resumen en inglés

We present records for six new stink bug species reported for Puerto Rico. These include two predatory species: Apateticus lineolatus (Herrich Schaffer) and Tylospilus acutissimus (Stal) (Asopinae); and four phytophagous species: Berecynthus hastator (R), Chlorocoris tau Spinola, and Acrosternum (Chinavia) ubicum Rolston (Pentatominae), and Alitocoris brunneus Sailer (Discocephalinae). Of these, B. hastatorhas been identified elsewhere as a vector of palm diseases, and A. brunneus appears to be a recent invasive species to Puerto Rico. Species reported here increase the number of stink bug species reported in Puerto Rico from 42 to 48, and the number of genera from 29 to 34. It is also the first report of a member of subfamily Discocephalinae on the island.

Superfamilies Aradoidea, Pyrrhocoroidea and Coreoidea from Puerto Rico are discussed as part of an updated account of Hemiptera: Heteroptera. In this final part, we present 48 species belonging to the three superfamilies, with six families known from Puerto Rico: Aradoidea: Aradidae (12); Pyrrhocoroidea: Largidae (1) and Pyrrhocoridae (3); and Coreoidea: Alydidae (5), Rhopalidae (7) and Coreidae (20). Taxonomic accounts presented here include synonymies, known distribution, lists of host plants and a listing of examined specimens. Taxonomical keys are also provided for the identification of all taxa included. Color plates for 43 species are included. Five species are new records for Puerto Rico: Brachyrhynchus membranaceus (F.), Leptoglossus confusus Alayo and Grillo, Eubule scutellata (Westwood), Mamurius cubanus Barber and Bruner, and Merocoris typhaeus (F.). Most species are widespread in the West Indies, with the largest number of island endemics in the Aradidae. A discussion of the origins, biodiversity, biogeography, and endemism of all Puerto Rican Pentatomomorpha is presented.
