查看更多>>摘要：A taxonomic revision of the genus Anoreina Bates, 1861, based on detailed study of the morphology of type species and the external morphology and terminalia of others, is presented. A new synonymy is proposed: A. pinimaiuba Martins & Galileo, 2008 = Oreodera simplex Bates, 1861. Anoreina helenae sp. nov. and A. roosevelti sp. nov. are described from Brazil. An identification key and distribution map of the seven species are provided.

查看更多>>摘要：The external morphology of eggs of the species Belminus corredori Galvao & Angulo, 2006, Belminus herreri Lent & Wygodzinsky, 1979 and Belminus ferroae Sandoval, Pabon, Jurberg & Galvao, 2007 is described for the first time using scanning electron microscopy (SEM). Females lay one egg at a time; the shape of the egg is oval with lateral flattening, a rounded caudal area and a true and simple convex operculum. The average size of the egg among these species is 0.51-0.58 mm in length and 0.36—0.4 mm in width. As a generic character we highlight the discovery of a chorion rim with one to four grooves always joined to the micropyles. All species present a clear polygonal pattern only in the operculum and in the egg's cephalic region, while the median and caudal regions show a smooth appearance, features that are shared only with the eggs of the genus Alberprosenia. A discriminant analysis of the polygonal design of the operculum proved to be useful for the identification of the species.

The new species is closely related to T. chilonis Ishii, the most widely distributed species in Pakistan and India. Morphological characters, ITS-2 sequence differences and reproductive data are presented to distinguish T. siddiqi n. sp. from T. chilonis.

Heterococcopsis opertus Borchsenius is transferred to a new genus Heterobrevennia Kaydan gen. nov. and the adult females of two new species belonging to Heterobrevinnia are described: H. gullanae Kaydan spec. nov. and H. kozari Kaydan spec. nov. Heterococcopsis desertus Bazarov & Nurmamatov is transferred to the genus Phenacoccus Cockerell.
查看更多>>摘要：Draconirvana, gen. n., is described and illustrated based on a single new species D. siamensis, from Thailand. The new genus is morphologically intermediate between Evacanthini and Nirvanini but is placed in the latter tribe based on its depressed form and the incomplete longitudinal carina on the face.
