Seven new species are described from Colombia: Anacroneuria citara, A. otun, A. pastora, A. quimbaya, A. tatama, A. tayrona and A. tunasi. The first Colombian records are given for A. bari Stark, A. curiosa Stark and A. harperi Stark; the latter two species were previously known from Mesoamerica and this is their first report from South America. New records, mainly in the Andinum natural region, are presented for 20 previously reported Colombian species. In addition, the unknown females of A. calima Baena & Rojas, A. marta Zúñiga & Stark and A. yameo Stark & Sivec are described, and three unassociated females are described under informal designation.

    ABSTRACT: Several factors influence the latitudinal distributions of organisms, including habitat heterogeneity, ecological requirements, historical events, and the influence of temperature and latitude, amongst others. We evaluate the distributions and diversity of Plecoptera on local (latitudinal gradient in Chile) and global scales. In Chile, 66 species from 35 genera and 6 families are recognized, with an endemism of 60 %. Species richness is greatest between the Maipo and Aysén river basins (34-45°S), and especially in the Valdivia region (39-40°S). The most widely distributed species are Limnoperla jaffueli and Antarctoperla michaelseni. The results of this work extend the distribution of several species and suggest that the latitudinal distribution of the order responds mainly to sampling effort, although lower differences in latitudinal diversity are expected due to the characteristics of Chilean rivers (except in the dry zone, 17-30°S). The two ecological factors that seem to be the most important in Plecoptera distributions, in Chile and around the world, are cold temperatures and good water quality. Thus, at global scale, diversity increases from the Equator toward the poles, with differences in the number of families and species between the Southern and Northern hemispheres, possibly due to differences in the number of studies done at the species level.

These recent additions bring the number of recognized species in this large genus to more than 300 (Stark unpublished) with no apparent end in sight. "

    ABSTRACT: Anacroneuria marshalli, a previously unknown stonefly species, is described from a single male specimen collected in Salta, Argentina, and new records are given for A. camposi (Banks) and A. kondratieffi Stark, two Ecuadorian species known only from holotype specimens.

    ABSTRACT: Total body length and head capsule width (mm) were used as biometric characteristics in discriminating between size-frequency estimates of three Anacroneuria morphospecies, from 28 sampling sites along a tropical river subject to bimodal variations in water level in Central Colombia. A total of 344 specimens grouped into four size classes were collected. The highest abundance of Anacroneuria larvae was observed during the dry season and there was a higher abundance of small-sized individuals (body length <12mm). overall, the highest abundance of stonefly larvae was recorded between 1000 to 1600m.a.s.l. Conductivity and pH showed a significant correlation with the total abundance of preimaginal stonefiles. Plecoptera size distribution patterns could be useful in assessing which stonefly size-spectra are susceptible to disturbance in tropical rivers and in evaluating their population dynamics.
