“…Moure & Hurd (1987) This synonym was adopted until the study of Engel (1996) in which H. glabrescens was again transferred to Halictillus based on an indirect examination of the syntypes on his behalf by F. Koch of ZMB. This most recent interpretation was followed by Engel (2000), Michener (2000Michener ( , 2007, Moure (2007) and Gonçalves (2010).…”

“…In the current classification (Engel 2000, Michener 2007, Moure 2007, Halictillus has two species, H. loureiroi (Moure), the type species, from southern Brazil and H. glabrescens from Chile. The genus belongs to an augochlorine subtribe that has other five genera, mostly from the southern Neotropics (Gonçalves 2010).…”

“…The genus belongs to an augochlorine subtribe that has other five genera, mostly from the southern Neotropics (Gonçalves 2010). Halictillus is very similar in size and overall body ornamentation with Dialictus (Halictini) and both are easily confounded (Eickwort 1969b, Engel 2000. Aside from the study of nesting biology made by Janvier (1926) nothing is known about the biology of Halictillus species.…”

-A lectotype is newly designated for Halictus glabriventris Friese (a homonym and replaced by H. glabrescens Cockerell) and the name transferred from Halictillus (Augochlorini) to Dialictus (Halictini), where it is a junior synonym of Dialictus spinolae (Reed). This placement resolves a long standing confusion involving the association of this name with a nest description from the beginning of the last century. In addition, a new species of Halictillus from Chile is described and figured.

“…1). Beside these characters, the females in these four genera are also remarkable for possessing a well-developed wax-extruding transverse area on their A sister-group relationship of this group with the genera Corynura and Halictillus was proposed by Engel (2000) based mainly on the possession of a galeal comb. Although other characters also support the group, such as the curved S6 gradulus and the apical spine on male volsella, they must be cautiously considered due to their high levels of homoplasy when other Augochlorini genera are taken into consideration in a broader phylogeny of the tribe (R.

ABSTRACT. Phylogeny and revision of the bee genus Rhinocorynura Schrottky (Hymenoptera, Apidae, Augochlorini), with comments on its female cephalic polymorphism. A taxonomic revision and a phylogeny for the species of Rhinocorynura are provided. Six species are recognized: R. briseis, R. crotonis, R. inflaticeps and R. vernoniae stat. nov., the latter removed from synonymy with R. inflaticeps, in addition to two newly described species, R. brunnea sp. nov. and R. viridis sp. nov. Lectotypes for Halictus crotonis Ducke, 1906 and Halictus inflaticeps Ducke, 1906 are hereby designated. Another available name included in Rhinocorynura, Corynuropsis ashmeadi Schrottky, 1909, is removed from the genus and treated as species inquerenda in Augochlorini. Rhinocorynura is monophyletic in the phylogenetic analysis and the following relationships were found among its species: (R. crotonis (R. briseis ((R. brunnea sp. nov. + R. viridis sp. nov.) (R. inflaticeps + R. vernoniae)))). Biogeographic relationships within the genus and comparisons with related taxa are presented. Females of all species exhibit pronounced variation in body size, in two of them, R. inflaticeps and R. vernoniae, with structural modifications possibly linked to division of labor. Identification key and illustrations for the species are provided. KEYWORDS. Apoidea; Halictidae; macrocephalic; parasocial.RESUMO. Filogenia e revisão taxonômica das abelhas do gênero Rhinocorynura Schrottky (Hymenoptera, Apidae, Augochlorini), com comentários sobre o poliformismo cefálico das fêmeas. São apresentadas uma revisão taxonômica e filogenia para as espécies de Rhinocorynura. Seis espécies são reconhecidas, duas descritas como novas, R. brunnea sp. nov. e R. viridis sp. nov., e quatro com nomes disponíveis, R. briseis, R. crotonis, R. inflaticeps e R. vernoniae stat. nov., esta última removida da sinonímia com R. inflaticeps. Designam-se aqui lectótipos para Halictus crotonis Ducke, 1906 e Halictus inflaticeps Ducke, 1906. Outro nome disponível incluído em Rhinocorynura, Corynuropsis ashmeadi Schrottky, 1909, é removido do gênero e tratado como species inquerenda em Augochlorini. O gênero Rhinocorynura resultou monofilético nas análises filogenéticas, com as seguintes relações encontradas para suas espécies: (R. crotonis (R. briseis ((R. brunnea sp. nov. + R. viridis sp. nov.) (R. inflaticeps + R. vernoniae)))). As relações biogeográficas dentro do gênero e comparações com táxons relacionados são apresentadas. Fêmeas de todas as espéci-es exibem variação pronunciada de tamanho corporal, em duas delas, R. inflaticeps e R. vernoniae, com modificações estruturais possivelmente relacionadas à divisão de trabalho. São apresentadas chave de identificação e ilustrações para as espécies.

Visual adaptations in the night‐active wasp Apoica pallens

The apposition compound eye of the nocturnal polistine wasp Apoica pallens shows, in comparison to the closely related diurnal wasp Polistes occidentalis, specific adaptations to vision at low light intensities. When considering recent work on nocturnal and diurnal bees, general principles for dim-light vision in hymenopterans become evident: The rhabdom diameters in nocturnal bees and wasps are 4 times wider compared to their diurnal relatives, leading to wide receptive fields, which in turn account for a 25-fold higher optical sensitivity. Interestingly, the rhabdom diameters in both nocturnal bees and wasps measure 8 mum, which may represent the maximum width for nocturnal hymenopteran apposition eyes. A ratio of 1.8 times larger eyes is present in the nocturnal bees and wasps, which in A. pallens is achieved by increasing the facet number, instead of enlarging the facets, as in nocturnal bees. Although this initially indicates spatial resolution to be important for the nocturnal wasp, the wide receptive fields of the rhabdoms will reduce its potentially high acuity. As the optical sensitivity alone cannot account for the 8 log units intensity difference between day and night, a possible role of neural summation within the first optic ganglion (lamina) of nocturnal hymenopterans is discussed.
