Revision of the Leucosphyrus group of Anopheles (Cellia) (Diptera, Culicidae)

Revision of the Leucosphyrus Group of Anopheles (Cellia) (Diptera, Culicidae). This is a comprehensive revision of 20 species of the Leucosphyrus Group of the Neomyzomyia Series of Anopheles (Cellia). Morphological description of the adults, male and female, male genitalia, pupa and fourth-instar larva are provided for each taxon in addition to bionomics, distribution data and systematic discussion for each species, including diagnostic characters. Identification keys for females and fourth-instar larvae are provided. When possible medical importance of each species is included. Illustrations of of the adults, fourth-instar larvae and pupae are provided. Distribution maps for each species are mainly based on the material examined; however, when possible published data were also used. Tables on adult character variations, fourth-instar larval and pupal setal branching are included as appendices. A neotype for An. takasagoensis Morishita and An. sulawesi Koesoemawinangoen, and a lectotype for An. balabacensis Baisas, are designated. The authorship of An. sulawesi previously cited as Waktoedi is corrected to Koesoemawinangoen.

A new genus and species of gall midge (Diptera, Cecidomyiidae) associated with Parkia pendula (Fabaceae, Mimosoideae)

The species of membracids described by C. Berg and M. Spinola classified in Sundarion Kirkaldy (Hemiptera, Cicadomorpha, Membracidae)

Pyranthe acaciae Berg, 1883 and Hemiptycha chilensis Spinola, 1852 are reinstated in Sundarion Kirkaldy, 1904 (formerly in synonymy of Callicentrus bonasia (Fabricius, 1775) (Centrotinae, Nessorhinini)). Pyranthe frustratoria Berg, 1883 (also formerly considered as synonym of Callicentrus bonasia) becomes a new synonym of Sundarion flavomarginatum (Fairmaire, 1846).

Cordiluroides Albuquerque from Costa Rica: first records, descriptions and taxonomic changes (Diptera, Muscidae, Coenosiinae)

Cordiluroides Albuquerque is a genus of Neotropical Coenosiinae (Muscidae), known from six species. The genus is here recorded for the first time from Costa Rica, on the basis of three species: C. listrata Albuquerque, 1954, C. insularis (Willliston, 1896) and C. bistriata (Wulp, 1896) sp. rev.. We provide a key for the identification of these Costa Rican species, redescribe and illustrate their external morphological characters and terminalia. C. bistriata and C. vittifera (Stein, 1904) are both considered to be good species and are re-instated from the synonymy of C. insularis. The type material of C. listrata (Museu Nacional, Rio de Janeiro), of C. insularis and C. bistriata (The Natural History Museum, London) and of C. vittifera (Museum für Naturkunde, Humboldt-Universität zu Berlin) has been examined.

Revisionary notes on the fungus-growing ant genus Mycetarotes Emery (Hymenoptera, Formicidae)

Mycetarotes is a small genus of the exclusively Neotropical fungus-growing ants, that includes M. parallelus (Emery), M. senticosus Kempf, M. acutus Mayhé-Nunes and M. carinatus Mayhé-Nunes. We hereby revise historical and recent information regarding Mycetarotes species for the first time, providing an identification key to workers, diagnoses, synoptic illustrated redescriptions of the species, including those of sexuals when known, updates of distributional records, and nest pictures of M. carinatus and M. parallelus. We comment the taxonomy and phylogenetic relationships among Mycetarotes and related genera, and on their geographical distribution. The available biological information on the genus is summarized.

A new species of Cervellus Szépligeti (Hymenoptera, Braconidae, Braconinae) with biological notes

A new Cervellus species is described from Brazil. The male to this genus is described for the first time as well its cocoon is illustrated.

The other species, recently redescribed or described are only diagnosed, except for H. deani Painter, 1930, whose spermathecae are described and illustrated for the first time. The main characters of the external morphology were photographed and the male genitalia and female spermathecae illustrated. An identification key to all included species is also presented.
