Ectoparasitic insects (Diptera: Streblidae and Siphonaptera: Ischnopsyllidae) of bats from Iquitos and surrounding areas (Loreto, Peru).

Based on specimens collected from bats of different families, we add new species and extend the known ecological distribution and host associations of insect ectoparasites of bats in Peru. New information is provided for the distribution of 26 species of parasites (25 Diptera and 1 Siphonaptera: Ischnopsyllidae). Four species (Neotrichobius ectophyllae, Strebla galindoi, Strebla paramirabilis and Myodopsylla wolffsohni wolffsohni) are new for Peru and 16 represent new records for the department of Loreto.

Taxonomy and distribution of Nonnapsylla Wagner, 1938 (Siphonaptera: Stephanocircidae: Craneopsyllinae).

The genus Nonnapsylla Wagner, 1938 (Craneopsyllinae) includes only 1 species, Nonnapsylla rothschildi Wagner, 1938 . Two subspecies are recognized by the shape of the dorsal margin of the helmet, apical shape of the spines in helmet and genal combs, length of first and fourth segments of the maxillary palpus, and shape of the hilla of the spermatheca. The validity of the characters used to separate the 2 subspecies of Nonnapsylla rothschildi Wagner, 1938 is discussed based on information from the literature, as well as from direct observation of type specimens and specimens collected in northwestern Argentina.

New records of bat ectoparasites (Diptera, Hemiptera and Siphonaptera) from northern Argentina.

New species of bat-ectoparasite insects are added to the fauna of Argentina and distributional limits are extended for others, based on information obtained from 21 species of bats collected. New data is reported for the distribution of 23 species of bat ectoparasites, of which 17 belong to the Order Diptera [14 Streblidae: Anastrebla caudiferae Wenzel, Anatrichobius scorzai Wenzel, Aspidoptera phyllostomatis (Perty), Megistopoda aranea (Coquillett), M. proxima (Sèguy), Metelasmus pseudopterus Coquillett, Noctiliostrebla aitkeni Wenzel, N.

First report of Polygenis (Polygenis) roberti beebei (Fox, 1947) (Siphonaptera: Rhopalopsyllidae) in Argentina, with a new host record and morphological data.

In the present study we report the presence of Polygenis (Polygenis) roberti beebei (Fox, 1947) for the first time in Argentina (23 degrees 56'S, 64 degrees 28'W, Jujuy Province). A new host record (the rodent Oryzomys russatus) and morphological details are also presented. Although the Argentinean specimens fit descriptions and illustrations given previously, the only studied male differs from the specimens collected from other localities in the characteristics of its aedeagus.
