“…In Logima adumbrata (Satchell 1953) and Falsologima savaiiensis (Edwards 1928), Satchell (1953) notes a "sensory cone" on each of the three apical fl agellomeres. Similar cones (named "spines") are also cited by Cordeiro & Bravo (2008) in Psychoda amazonensis Cordeiro & Bravo 2008. Goblet-shaped organs, named "sensilla coeloconica" by Campbell & Pelham-Clinton (1960) and "sensilla ampullaceal" by Wirth & Navai (1978), are present in Culicoides sp.…”

Abstract. The pollination of the genus Arum (Araceae) is mainly achieved by deception, the fl oral odour mimicking the pollinator ovipositing site. In order to discover the sensory organs involved in this attraction, we have studied the antennae of fi ve species of psychodine moth-fl ies (former Psychoda sensu lato = Psychodini), pollinators of Arum spp. The antennae of the fi ve Psychodini reveal seven types of sensilla: multiporous tribranched sensilla basiconica (sensilla ascoidea), multiporous sensilla basiconica, multiporous sensilla coeloconica, multiporous sensilla auricillica, uniporous sensilla basiconica, aporous sensilla chaetica, aporous Böhm's sensilla. Each species possesses three, fi ve or six of these sensillum types. All the multiporous sensilla are probably olfactory receptors while the uniporous sensilla basiconica must possess a contact chemoreceptive function. The multiporous tribranched sensilla basiconica (s. ascoidea), present in all the species, are the best candidates for the reception of the odours given off by the ovipositing sites and the infl orescences of Arum. The multiporous sensilla basiconica and the multiporous sensilla coeloconica may be involved respectively as CO 2 receptors or thermoreceptors. Psychoda phalaenoides, which is the main pollinator of A. maculatum, is the species which possesses the largest number of antennal sensilla. The sexual dimorphism, studied only in Psycha grisescens, as concerns the number of sensilla and the absence of a sensillum type which differ according to sex, is diffi cult to interpret.Résumé. Sensilles antennaires de cinq espèces de Psychodini (Diptera : Psychodidae : Psychodinae) pollinisateurs du genre Arum (Araceae). La pollinisation du genre Arum (Araceae) est réalisée essentiellement par tromperie, l'odeur fl orale imitant les sites d'oviposition du pollinisateur. Afi n de rechercher les organes sensoriels impliqués lors de cette attraction, noue avons étudié les antennes de quelques espèces du genre Psychoda sensu lato, pollinisateurs des Arum. Les antennes des cinq Psychodini montrent l'existence de sept types sensillaires : des sensilles basiconiques multipores à trois branches (sensilles ascoïdes), des sensilles basiconiques multipores, des sensilles coeloconiques multipores, des sensilles auricilliformes multipores, des sensilles basiconiques à pore terminal, des sensilles chétiformes sans pore et des sensilles de Böhm sans pore. Chaque espèce possède trois, cinq ou six de ces types sensillaires. Toutes les sensilles multipores sont probablement des récepteurs olfactifs tandis que les sensilles basiconiques unipores possèdent une fonction chimio-réceptrice de contact. Les sensilles ascoïdes présentes en grands nombres chez toutes les espèces sont les meilleures candidates pour la réception des odeurs en provenance des sites d'oviposition et des infl orescences d'Arum. Les sensilles multipores basiconiques et coeloconiques peuvent être impliquées respectivement dans la réception du CO 2 ou comme thermorécepteurs. Psychoda phalaenoide...

“…The genus Psychoda Latreille, 1796 currently comprises 59 species in the Neotropical Region , Cordeiro & Bravo 2008, six of them from Brazil. In the present paper, a new species of Psychoda is described from the State of São Paulo, Brazil, based on a single imago and his pupal exuviae sent us by Gustavo Romero.…”

With a big territory and variety of biomes, Brazil is one of the most diverse countries in the World, with insects massively contributing to this diversity. Although presenting impressive numbers, many groups are poorly known concerning their diversity and distribution. Also, the knowledge of the species diversity is very heterogeneous when comparing Brazilian states and regions. With a recent review of part of Lawrence Quate’s collection deposited at Natural History Museum of Los Angeles County, more than 70 new geographical records for Psychodidae species were found on the Neotropics, including one genera (Eurygarka) and seven species first recorded to Brazil. The complete known distribution of these species was compiled and is presented along with new records for other 11 countries of the Neotropical region. On the Brazilian territory, most of the new records are for the state of Rondônia, on the northern region, followed by Minas Gerais, on the southeastern region.
