TEJERINA, Eva G.  and  MOLINERI, Carlos. Chironomidae (Diptera) communities from Northwestern Argentinean mountain streams: comparison between Yungas and Monte. Rev. Soc. Entomol. Argent. [online]. 2007, vol.66, n.3-4, pp.169-177. ISSN 0373-5680.

Chironomid communities in two geographic areas were studied: one from the biogeographic province of Monte, and the other from Yungas (at two altitudinal levels, low mountain jungle and the high mountain forest). A taxonomic list is firstly presented for the region, including 15 genera in five subfamilies. The studied sites from Monte region were characterized by high densities of Pentaneura sp., Parametriocnemus sp., and Podonominae spp. Lopescladius sp. appeared only in Yungas (both low and high levels). Pseudochironomus sp. and Orthocladiinae 1 are characteristic of the higher levels in Yungas , while lower Yungas sites showed higher densities of Onconeura sp. and Rheotanytarsus sp. The highest sites (from Monte and higher Yungas) shared the occurrence of the cold stenothermic taxa Podonominae and Diamesinae.

Keywords : Yungas; Monte; Podonominae; Diamesinae; Orthocladiinae; Chironominae; Tanypodinae.
