Panurgine bees are diverse and abundant in temperate areas of the Americas but poorly represented to nearly absent in the tropics. We describe and illustrate five distinctive new species of the genus Protandrena that occur at high altitudes (2000-3400 m) in the Andes, from Venezuela to Ecuador. The species are also described to make the names available in forthcoming papers on their biology. These Andean species resemble some members of the subgenus Heterosarus but differ from it, as well as from any other subgenera of Protandrena, primarily in characters of the male genitalia and hidden sterna. The South American Protandrena s. l. are morphologically highly diverse and a complete study of the group is needed before supraspecific names are proposed for unusual species. Thus, to avoid further nomenclatural changes, we decided not to place these species in a new subgenus or any of the available subgenera. We also provide notes on the biology for some of the species.

The Neotropical genus Lycomorphon Pic, 1922 is revised. Eleven species are classified in the genus, six of them are redescribed, five species (Lycomorphon brasiliense sp. n., L. amazonicum sp. n., L. bimaculatum sp. n. L. bolivianum sp. n., L. fulvohumeralis sp. n.) are proposed as new to science. Lycomorphon elongaticolle v. diversicolle Pic, 1926 is raised to species status, and Idiopteron irregularis is transferred to the genus Lycomorphon. The new subgenus Spinolycus sg. n. is proposed within Lycomorphon.

33 species of Chrisopini are described and illustrated, of wich 30 are recorded from the Amazon Basin. Ten new species are described in Chrisopodes(duckei, spínella, nebulosa, lineafrons, polygonica, indetata, conisetosa, breviata, mediocris, and tetifera(, and nine in Ceraesochrysa(squalidens, acutipuppis, rafaeli, reddyi, nigripes, teneuícornis, ariasi, falceifera, and michaelmuris). Neosuarus (type species collaris (Schneider), a new subgenus of Chrysopodes, also contains divisa (Walker), escomeli (Navás) porterina (Navás), and flavescens (Blanchard). Orlandsia Navás and Ancylochrysa Navás are synonymized with Chrysopodes limbata (Navás), Chrysoperla asoralis (Banks) and Suarius nesotala (Banks). A neotype is designate for Ceraeochrysa cubana (Hagen). Ceraeochrysa caligata(Banks) and scapularis (Navás) are valid species. C. gloriae Alayo is synonymized with Ceraeochrysa everes (Banks).

Water mites from Andean part of the Bolivian Amazonian rivers were examined. A new species is described, Limnesia aymara. New records and redescription are made for Hygrobatella multiacetabulata Cook,1980, Atractides brasiliensis (Lundblad, 1937) and Krendowskia convexa (Ribaga, 1902). A new subgenus Schwoerbelobatella for hygrobatelids poliacetabulated is proposed and characterized. Ecological characteristics of the river area sampled and ecological preferences of the analyzed species are discussed.

The systematic positon of Trypanosoma rangeli is reconsidered and the creation of a new subgenus. Tejeraia, is proposed to remove this trypanosome from the subgenus Herptosoma of the section Stercoraria. The characteristics described for the proposed subgenus indicate that it must be located in the section Salivaria rather than in the Stercoraria. The evidence supporting this proposition is discussed in the text.

A new subgenus Glossuropoda is proposed for Euglossa intersecta Latreille, 1837, as the type species. It is distinguished from Glossura by having a very peculiar configuration of the mid basitarsus of the male and lack of the median spur. Two new species Euglossa (Glossuropoda) hugonis, from Tabatinga, AM - Brasil, and Euglossa (Glossuropoda) juremae, from Vigia, PA - Brasil, belonging to the same subgenus but strickingly different from the type species by their prevalent green color with brassy and golden hue on the last abdominal segments and hind legs.

During a research project aimed at the study of the Culicinae fauna of Gabon and carried out in the National Park of La Lopé, we captured an unknown sandfly male specimen (genus Phlebotomus) by CDC miniature light trap belonging to a new species for Science. Furthermore, the originality of his genitalia does not allow us to include this species in one of the existing subgenus, thus in this paper we propose the creation of a new subgenus, as Phlebotomus (Legeromyia) multihamatus sp. nov., subg. nov. described from the National Park of La Lopé, through one male captured with CDC miniature light trap. A new species and a new subgenus of sandfly is characterised by a short style with three spines, a paramere wearing a basal hook as well as a basal pouch and the absence of basal lobe on the coxite. The originality of the genitalia of the male gives way to discussion about potential primary homologies between P. multihamatus sp. nov. and Phlebotomus (Abonnencius) fortunatarum, Phlebotomus (Anaphlebotomus) stantoni and Phlebotomus (Euphlebotomus) argentipes, which should be verified for future studies. The discovery of this new species in Gabon must encourage the study of sandflies in this country.

The fossil crown wasp Electrostephanus petiolatus Brues comb. rev.(Stephanidae, Electrostephaninae) is re-described from a single male preserved in middle Eocene Baltic Amber. The holotype was lost or destroyed around the time of World War II and subsequent interpretations of its identity have been based solely on the brief descriptive comments provided by Brues in his original account. The new specimen matches the original description and illustration provided by Brues in every detail and we hereby consider them to be conspecific, selecting the specimen as a neotype for the purpose of stabilizing the nomenclature for this fossil species. This neotype exhibits a free first metasomal tergum and sternum, contrary to the assertion of previous workers who indicated these to be fused. Accordingly, this species does indeed belong to the genus Electrostephanus Brues rather than to Denaeostephanus Engel & Grimaldi (Stephaninae). Electrostephanus petiolatus is transferred to a new subgenus, Electrostephanodes n. subgen. , based on its elongate pseudo- petiole and slender gaster, but may eventually warrant generic status as the phylogenetic placement of these fossil lineages continues to be clarifi ed. A revised key to the Baltic amber crown wasps is provided.

The family Leuconidae currently contains 99 species. With the exception of Epileucon, all genera in the family were established by 1907. All new species have been subsequently assigned to those genera, gradually producing genera distinguishable on the basis of single characters. In this paper Epileucon is reduced to a subgenus of Leucon as proposed by Bacescu (1988), and the species of Leucon are further apportioned among the subgenera Leucon Kroyer, Macrauloleucon, new subgenus, Crymoleucon, new subgenus, and Alytoleucon, new subgenus. In addition, the new genera Ommatoleucon, Austroleucon, Nippoleucon, and Bytholeucon are proposed, and the genus Coricuma Watling and Breedy is added to this family. The new genus Americuma, with unclear family affiliations, is proposed for a species previously assigned to Heteroleucon. Complete diagnoses are provided for all genera and keys are given to all genera and species.

The subgenus Trichopygomyia Barreto, 1962 of the phlebotomine genus Lutzomyia França, 1924 is reviewed. This subgenus corresponds to the informal species group longispina of Theodor (1965). Lutzomyia (Trichopygomya) ratcliffei n.sp. from the Brazilian Amazon Basin is described. Figures, keys, distribution maps and notes on ecology are presented for all the known forms. The better known species are most frequently encountered in armadillo burrows and, therefore, could well be vectors of Leishmania.
