RESUMO
Twenty two years after the first checklist of Neotropical Spider Wasps, a new list of genera and species is offered, including novelties in phylogeny and systematics, as well as reviews, synonyms and descriptions since the year 2000. Sixty three genera and 946 species of Pompilidae are listed.

Species of spider wasps (Hymenoptera: Pompilidae) are diverse in the tropical regions. The Neotropical genus Abernessia Arlé, 1947 was described from São Paulo and later found in Espírito Santo, Bahia and Minas Gerais, Brazil. Herein, we establish a neotype for the type-species A. irmgardae Arlé, discuss the previous distribution records of Abernessia in South America, add new records for Brazil, and expand the recorded distribution to San Pedro, Paraguay. The male of Abernessia giga is described and illustrated. Finally, an updated key to species known from males is provided.

Ageniella Banks is the second most diverse genus in the tribe Ageniellini (Pompilidae: Pepsinae) with about 200 valid names. Ageniella is known to be paraphyletic; yet, no revision has been made. Lack of a taxonomic catalogue and of identification keys has further delayed taxonomic studies. Additionally, many of the currently valid names should be treated as synonyms. This present study is the first attempt to organize the species of Ageniella, focusing on the species occurring in Brazil. A total of six subgenera and 40 species of Ageniella occur in Brazil. Of these, 25 species are endemic to Brazil. The new synonyms are proposed for (valid names are first): Alasagenia Banks, 1944 =Lissagenia Banks, 1946, syn. nov.; Ageniella (Alasagenia) erichsoni Banks, 1944 =Priophanes major Banks, 1945, syn. nov.; Ageniella (Ameragenia) zeteki (Banks, 1925) =Priophanes marcida Banks, 1946, syn. nov.; Ageniella (Ameragenia) agitata (Smith, 1873), comb. nov. =Salius (Priocnemis) setaceicornis Fox, 1897, syn. nov.; Ageniella (Ameragenia) sanguinolenta (Smith, 1864) =Agenia ruficeps Smith, 1864, syn. nov.; =Ageniella alternata Banks, 1946, syn. nov.; Ageniella (Priophanes) dolorosa (Banks, 1946), comb. nov. =Priophanes plagosa Banks, 1946, syn. nov.; Ageniella (Ameragenia) fabricii (Banks, 1944) =Ameragenia notabilis Banks, 1946, syn. nov. A new combination is proposed for: Ageniella (Alasagenia) cursor (Smith, 1873), comb. nov. (from Agenia Schiødte); Ageniella (Ameragenia) clypeata (Fox, 1897), comb. nov. (from Salius Fabricius), Ageniella (Ameragenia) rutila (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) tegularis (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) rufitarsis (Fox, 1897), comb. nov. (from Salius), Ageniella (Ameragenia) citricornis (Fox, 1897), comb. nov. (from Salius), Ageniella (Ameragenia) serrula (Fox, 1897), comb. nov. (from Salius), Ageniella (Priophanes) cingulata (Fox, 1897), comb. nov. (from Agenia). A new name Ageniella (Ameragenia) banksii Waichert, nom. nov. is proposed for Ameragenia festina Banks, 1946, secondary homonym of Ageniella festina Banks, 1917, and Ageniella (Priophanes) otiosa is reinstate, stat. resurr.

Genitalia are rich source of characters in insect taxonomy. Usually, they are examined after dissection and cleaning with potassium hydroxide (KOH), procedure that may damage both genital morphological structures and intracellular molecular contents. Enzymatic procedure with Proteinase K has been used to clean muscle off the genitalia while extract DNA, but its damage to the genital structures has not been evaluated. Herein, we qualitatively compare the use of KOH and Proteinase K to prepare genital structures in minute insects (Hymenoptera: Bethylidae). We show that Proteinase K is better to preserve the genital structure and provides quality DNA.

Aporinellus Banks, Austrochares Banks and Dicranoplius Haupt are new generic records for Colombia, as well as the species Dipogon ariel Banks, Evagetes peruana Banks, and Euplaniceps notabilis (Smith). Five new combinations are formally endorsed: Aimatocare argentinica (Banks), comb. n.; Aimatocare longula (Banks), comb. n.; Aimatocare imitator (Evans), comb. n.; Aimatocare impensa (Evans), comb. n.; Aimatocare vitrea (Fox), comb. n. Although these names have been used in Pompilidae, no formal nomenclatural act had been proposed. The presence of Chirodamus paramicola Roig-Alsina, previously reported with uncertainty, is confirmed. Finally, a new combination for Euplaniceps notabilis (Smith), comb. n. is proposed based on molecular phylogenetics and morphological data. The Colombian fauna of Pompilidae sums up to 38 genera and approximately 150 species.
RESUMO
It is difficult to make reliable sex associations in several species of Hymenoptera due to sexual dimorphism. Only a few species of the flat wasp genus Dissomphalus Ashmead, 1893 have had their sexes associated, since females are rarely collected and differ morphologically from their conspecific males. Collecting couples during their phoretic copula is difficult, but it is the most reliable way to associate the sexes in Dissomphalus . Herein, we associate the sexes and discuss the mating system based on couples of six Dissomphalus species collected during copulation: D. bisserratus Azevedo, 1999, D. connubialis Evans, 1966, D. rettenmeyeri Evans, 1964, D. simulatus (Evans, 1969), comb. nov., D. mendicus Evans, 1969, and D. firmus Redighieri & Azevedo, 2006. The females of the latter three are described for the first time. The distribution of two species is expanded. Apenesia simulata Evans, 1969 is transferred to Dissomphalus and is now D. simulatus comb. nov. Finally, we briefly discuss the genital structures used during phoretic copulation, analyzing the male and female genitalia in copulation. During copulation, the mating female is attached to the male only by the genitalia and is apparently grasped by muscles attached to the male's metasoma.
