Enneothrips Hood: a Neotropical genus of leaf-feeding thrips (Thysanoptera: Thripidae) with generic diagnosis and four new species.

Enneothrips is a lineage of leaf-feeding thrips conventionally placed in the Anaphothrips genus-group (Thripinae) and exclusively found in the Neotropics. Here we describe E. amazonicus sp. n., E. fulbrightae sp. n. and E. manauara sp. n. from the Brazilian Amazon and E. atlanticus sp. n. from the Brazilian Atlantic Forest, together with an illustrated key to all ten species now recognized in the genus.

Systematics and species recognition in Oneilliella Wilson (Thripidae: Panchaetothripinae).

Oneilliella is a poorly sampled Panchaetothripinae genus with two described species based on very few specimens. Here we provide further information about the genus and describe three species: O. chicoi sp. n. and O. wanessae sp. n. from Brazil, and O. tica sp. n. from Costa Rica. We discuss the relationships between Oneilliella and other members of Panchaetothripinae based on morphology. The Indian species Oneilliella shivii Singha et al. requires further study as it is probably not congeneric with the Neotropical lineage recognized here. An illustrated key to the five Oneilliella species is provided.

Identification of second instar larvae of Panchaetothripinae (Thysanoptera, Thripidae) in Brazil and Argentina.

In this paper, we present an illustrated key to second instar larvae of 17 of the 25 Panchaetothripinae species recorded in Brazil and Argentina, several of which are pests of many crops. In addition, comments on morphology and host associations are provided. Heliothrips longisensibilis is recorded for the first time in Argentina.
