ABSTRACT
A new species of aphid, belonging to the genus Macrosiphoniella Del Guercio, 1911, is described using three samples collected in Iran on Helichrysum armenium (Asteraceae, Inuleae) by the late Prof. G. Remaudière. Both apterous and alate viviparous females of the new taxon, Macrosiphoniella remaudiereisp. n., are described and compared to corresponding morphs of the closely allied Macrosiphoniella aetnensis and to other congeneric aphid species on Helichrysum in the Palaearctic region. Type specimens are now stored in the Muséum national d'Histoire naturelle in Paris.
ABSTRACT
A new species in one of the largest genera of Macrosiphini (Hemiptera, Aphididae), Acyrthosiphon pilosum sp. n., is described from apterous and alate viviparous females and oviparous females from French and Spanish Mediterranean localities, living on species of Ononis (Fabaceae), mainly O. natrix. The new species is characterized by the presence of many accessory setae on the ultimate rostral segment, and usually five setae on the first tarsal segments, a combination that is not present in any other known Acyrthosiphon species; in addition marginal tubercles are present on prothorax and several of abdominal segments 2-5.

Two new species of Aphidura Hille Ris Lambers, 1956 (Hemiptera, Aphididae, Macrosiphini) are described; Aphidura libanensis sp. n. from Prunus prostrata in Lebanon, and Aphidura corsicensis sp. n. from Cerastium soleirolii in Corsica (France). Studies of Aphidura bozhkoae specimens from different localities have revealed that this species varies in its pattern of dorsal sclerotisation and other morphological characters, within and between populations. An updated key for identifying the world's species of Aphidura is presented.
ABSTRACT
The number of described species on the planet is about 1.9 million, with ca. 17,000 new species described annually, mostly from the tropics. However, taxonomy is usually described as a science in crisis, lacking manpower and funding, a politically acknowledged problem known as the Taxonomic Impediment. Using data from the Fauna Europaea database and the Zoological Record, we show that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species. In Europe, new species of multicellular terrestrial and freshwater animals are being discovered and named at an unprecedented rate: since the 1950s, more than 770 new species are on average described each year from Europe, which add to the 125,000 terrestrial and freshwater multicellular species already known in this region. There is no sign of having reached a plateau that would allow for the assessment of the magnitude of European biodiversity. More remarkably, over 60% of these new species are described by non-professional taxonomists. Amateurs are recognized as an essential part of the workforce in ecology and astronomy, but the magnitude of non-professional taxonomist contributions to alpha-taxonomy has not been fully realized until now. Our results stress the importance of developing a system that better supports and guides this formidable workforce, as we seek to overcome the Taxonomic Impediment and speed up the process of describing the planetary biodiversity before it is too late.

A catalogue is presented containing 71 species of aphids and one phylloxerid from Panama. Fifty-nine species are new records for Panama and 12 of them are new records for Central America. Eleven species are of Neotropical origin and 17 are of Nearctic origin. Forty-four species own their presence in Panama to direct or indirect anthropogenic introduction. The catalogue records 227 "aphid species/host-plant species" relationships, with 25 new records "aphid species/host-plant genus".
Se establece el catálogo de los áfidos y filoxéridos de Panamá, respectivamente con 71 y one especies. Se citan por vez primera en Panamá 59 especies de áfidos y 12 de ellas por primera vez en América Central. Once especies son de origen neotropical y 17 tienen origen neártico; 44 especies tienen otros orígenes y su presencia en Panamá se ha de deber directa o indirectamente a introducciones antrópicas. Se proporcionan 227 relaciones "especie de pulgón / especie de planta hospedadora", con 25 nuevas relaciones "especie de pulgón / género de planta hospedadora".
