Abstract: Records of the aphid species and subspecies contained in 139 scientific contributions have been revised. New records of many species are presented from specimens conserved in the collections of Museum national d’Histoire naturelle (Paris, France), the Servicio Agricola y Ganadero (SAG) (Santiago, Chile), the Natural History Museum (London, U.K.), the universities of Leon (Spain) and Talca (Chile) and of J. Ortego (Mendoza, Argentina). The Chilean aphid-catalog is composed of 169 species and subspecies; Aphis (Toxoptera) citricidus, Aphis medicaginis, Aphis rumicis, Dysaphis apiifolia petroselini, Lipaphis erysimi and Uroleucon aaroni are excluded from the catalog. Aphis rubicola, Brachycaudus amygdalinus and Illinoia pepperi are first recorded from South America. Aphis forbesi, Aphis senecionicoides, Hyadaphis passerini, Hyperomyzus carduellinus, Illinoia azaleae, Neotoxoptera oliveri and Pentalonia nigronervosa are also recorded for first time from Chile. More a hundred new regional and provincial records are given. Host plant list of aphids recorded in Chile are presented for first time. The compositions of Chilean regional and provincial aphidfaunas are discussed. An evaluation of the allochthonous and autochthonous components of the Chilean aphidfauna is presented.

TL;DR: Uroleucon cichorii (Koch, 1855) Aphis intybii and Aphis fabae cirsiiacanthoidis Scopoli, 1763 colonies occurred on Cichorium intybus L., Cirsium arvense (L.) Scop.
Abstract: Uroleucon cichorii (Koch, 1855) Aphis intybii (Koch, 1855) and Aphis fabae cirsiiacanthoidis Scopoli, 1763 colonies occurred on Cichorium intybus L., Cirsium arvense (L.) Scop. was colonised by Aphis fabae cirsiiacanthoidis. Artemisia vulgaris L. accommodated Macrosiphoniella artemisiae (Boyer de Fonscolombe, 1841). The annual Crepis setosa Haller was the host plant of Uroleucon cirsii (Linnaeus, 1758) and Uroleucon cichorii. The perennial Picris hieracioides L. also accommodated Uroleucon cirsii. Centaurea arenaria M. Bieb. ex Willd. and Centaurea stoebe L. subsp. micranthos (Gugler) Hayek accommodated Uroleucon jaceae (Linnaeus, 1758). Carduus acanthoides L. was colonized by Uroleucon aeneum (Hille Ris Lambers, 1939). Artemisia absinthium L. was the host of Macrosiphoniella absinthii (Linnaeus, 1758). Achillea millefolium L. was colonized by Macrosiphoniella millefolii (De Geer, 1773).

TL;DR: A total of 64 species from 17 genera of the family Aphidiidae (Hymenoptera) from Great Britain is identified in the collection of the Manchester Museum.
Abstract: A total of 64 species from 17 genera of the family Aphidiidae (Hymenoptera) from Great Britain is identified in the collection of the Manchester Museum (University of Manchester, UK). Nine species are recorded from Great Britain for the first time: Aphidius absinthii Marshall, 1896, A. arvensis Starỳ, 1960, A. linosiphonis Tomanovic et Starỳ, 2001, Diaeretellus macrocarpus Mackauer, 1961, Ephedrus longistigmus Gardenfors, 1986, Monoctonus mali van Achterberg, 1989, Praon uroleucon Tomanovic et Kavallieratos, 2003, Trioxys humuli Mackauer, 1960, and T. lambersi Mackauer, 1960. Supplemented descriptions of 2 rare species, Trioxys macroceratus Mackauer, 1960 and T. ibis Mackauer, 1961, are given.
TL;DR: Two new species of the genera Uroleucon Mordvilko, 1914 and Pleotrichophorus Börner, 1930 are described from Kazakhstan, where the new species is similar to P. glandulosus and P. achilleae but differs from these species in the ratio of the length of dorsal hairs on tergites I–V to the basal diameter of the 3rd antennal segment.
Abstract: Two new species of the genera Uroleucon Mordvilko, 1914 and Pleotrichophorus Borner, 1930 are described from Kazakhstan. Uroleucon dzhungaricum sp. n. feeding on Senecio nemorensis L. (Asteraceae) in the Dzhungar Ala Tau is closely related to U. minor (Borner, 1940). Both these species differ from the closely related U. solidaginis (Fabricius, 1794) in a smaller length ratio between the processus terminalis and the 3rd antennal segment (0.8–1.0 versus 1.0–1.5). The new species differs from U. minor (Born.) in a greater number of the secondary rhinaria on the 3rd antennal segment of the apterous viviparous females (21–37 versus 15–21), in a fewer number of hairs on the cauda (10–16 and 15–23), and in the host plant. Pleotrichophorus ugamicus Kadyrbekov, sp. n. feeding on Artemisia santolinifolia Turcz. is described from the Sairam-Ugam Natural Park (Southern Kazakhstan). The new species is similar to P. glandulosus (Kaltenbach, 1846) and P. achilleae Holman, 1965. Pleotrichophorus ugamicus sp. n. differs from these species in the length ratio of the processus terminalis to the base of the 6th antennal segment (4.1–5.0 versus 5.0–9.0 and 5.1–6.2), in that of the ultimate rostral segment to the 2nd segment of the hind tarsus (0.68–0.76 versus 0.80–0.97 and 0.80–0.90), and in the host plant. This species differs from P. glandulosus in the ratio of the length of dorsal hairs on tergites I–V to the basal diameter of the 3rd antennal segment (1.0–1.2 and 1.4–1.7). In addition, the new species differs from P. achilleae in the length ratio of the 3rd antennal segment to the 6th segment (0.56–0.66 versus 0.70–0.87) and to the processus terminalis (0.67-0.82 versus 1.39–1.80), as well as in the shape of the dorsal hairs. A key to the Palaearctic species of the genus Pleotrichophorus is presented.
