785687E1FFE1FFB8D2A5FEDCFE012EDB.taxon	distribution	Distribution. Culex ameliae is known only from Argentina (Walter Reed Biosystematics Unit 2001), and is considered endemic to the type locality (Campos & Maciá 1998). Bionomics. Larvae of Cx. ameliae were collected in association with larvae of Cx. (Melanoconion) intrincatus Brethès, Cx. (Mel.) bejaranoi Duret, Cx. (Cux.) chidesteri Dyar and Cx. (Cux.) dolosus (Lynch Arribálzaga) (Casal 1967). Casal mentioned only that the larvae were collected in a flooded depression. Taxonomy. The larva of Cx. ameliae is very similar to the larva of Cx. chidesteri. The latter differs from Cx. ameliae in the following characters: the length of seta 4 - M is less than 0.50 of 5 - M, the thorax has spicules longer than 10 µm, the siphon is darker, seta 1 a-S is inserted within the pecten and the last pecten spine is more widely separated from the others.	en	Laurito, Magdalena, Almirón, Walter Ricardo, Rossi, Gustavo Carlos (2011): Description of the immature stages of Culex (Culex) ameliae Casal and Culex (Culex) articularis Philippi (Diptera: Culicidae).

785687E1FFE5FFBAD2A5F9B0FC772CF4.taxon	distribution	Distribution. Culex articularis is known from Chile, Argentina, Ecuador and Perú (Walter Reed Biosystematics Unit 2001). In Argentina it is recorded from the provinces of Neuquén, Río Negro (Campos & Maciá 1998) and Chubut (Rossi & Vezzani, unpublished data). Bionomics. Larvae of Cx. articularis were collected in Río Negro Province, at 620 m. a. s. l. with dry and cold climate. The environment is a fertile lowland that feeds the most important spring of Valcheta stream (near El Rincón farm). The stream has abundant coastal vegetation of the genus Cortadeira. Culex articularis was found associated with amphipods of the genus Hyalella. Seta Head Thorax Abdominal segments no.

Larvae of Cx. articularis are very similar to several species of the subgenus, including Cx. eduardoi Casal & García, Cx. brethesi Dyar, Cx. dolosus Lynch Arribálzaga, Cx. cuyanus Duret, Cx. archegus Dyar, Cx. carcinoxenus de Oliveira Castro and Cx. foliaceus Lane. The characters that distinguish Cx. articularis from these species are: pecten spines with one subapical denticle, longer antenna and saddle and higher siphon index in Cx. eduardoi; setae 0,2 - C absent, seta 1 - VIII with 7 − 9 branches and longer saddle in Cx. brethesi; conspicuous spicules (10 − 15 µm) covering the thorax and seta 3 - P double in Cx. dolosus; setae 16,17 - C present and one denticle in pecten spines in Cx. cuyanus; seta 1 - S with 5 and 4 - X with 4 elements, respectively, in Cx. archegus; Cx. carcinoxenus only inhabits crab holes; and siphon index higher than 5 and seta 1 - S with 4 elements in Cx. foliaceus. Furthermore, the last three species are not recorded from Argentina.	en	Laurito, Magdalena, Almirón, Walter Ricardo, Rossi, Gustavo Carlos (2011): Description of the immature stages of Culex (Culex) ameliae Casal and Culex (Culex) articularis Philippi (Diptera: Culicidae).

785687E1FFE5FFBAD2A5F9B0FC772CF4.taxon	discussion	Discussion. The fourth-instar larva of Cx. ameliae is distinguishable from other Cx. (Cux.) by the conspicuously longer seta 4 - M, and the pupa by the nearly perfectly cylindrical trumpet. The dorsal position of setae 0,2 - C and the medial and separated location of setae 1,2 - T relative to the other dorsal setae of the same segment easily distinguish the fourth-instar larva of Cx. articularis from other species of the subgenus. The pupa is very similar to other species of Cx. (Cux.), but differs in trumpet shape, which varies between conical and cylindrical, and having seta 2 - Pa stronger than 1 - Pa.	en	Laurito, Magdalena, Almirón, Walter Ricardo, Rossi, Gustavo Carlos (2011): Description of the immature stages of Culex (Culex) ameliae Casal and Culex (Culex) articularis Philippi (Diptera: Culicidae).
