| Em Cruz das Almas, BA, em outubro de 2004, foi verificada infestação de Trialeurodes variabilis (Quaintance) em mamoeiros 'Sunrise Solo', mantidos em telado. Nas folhas infestadas, detectaram-se níveis de parasitismo em ninfas da mosca-branca da ordem de 20%. Folhas com ninfas parasitadas foram mantidas em laboratório até emergência dos parasitóides, identificados como Encarsia hispida De Santis. Trata-se do primeiro registro de parasitismo de ninfas de T. variabilis por essa espécie de Encarsia no Brasil. |

| ABSTRACT First records of parasitoids attacking the Asian citrus psyllid in Ecuador. The objective of the current study was to investigate the presence of natural enemies of Diaphorina citri (Hemiptera: Liviidae) (the Asian citrus psyllid) in Ecuador. Incidence of parasitoid Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) was assessed between November 2015 and March 2016, in Letamendi, Febres-Cordero and Tarqui, urban districts of Guayaquil. Highest incidence of parasitism occurred in those regions and seasons of the year with the highest temperatures commensurate with increase of citrus plant shoots. Similar to their host, these parasitoids appear to have established in Ecuador by accident, and were not the result of purposeful introduction. This... |

| Emersonella Girault, 1916 is a wasp genus including species that parasitize Chrysomelidae (Coleoptera) eggs, mainly Cassidinae. It occurs only in the Americas, and is primarily distributed in the Neotropical Region. In this paper two new species of Emersonella from the Atlantic Forest of southeastern Brazil are described and compared to similar species. Emersonella appendigastersp. nov. is characterized by an elongate last gastral tergite in female, thoracic dorsum flat, femora and tibiae yellowish in female, malar sulcus absent, frontal suture slightly down-curved laterally, eyes with scattered hairs, frons and vertex smooth, and propodeum smooth with small anteromedian foveae. Emersonella frieirocostaisp. nov. is characterized by an elongate gaster in... |

| ABSTRACT The purpose of this short communication is to provide information on the depository for the primary types of the new species described by Alvarenga et al. (2015) and thus validate the names suggested therein. The depository for the primary types of the new species Emersonella appendigaster Alvarenga, Costa & Hansson, 2015 and Emersonella frieirocostai Alvarenga, Costa & Hansson, 2015 is the Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil (MZSP). |
