Cytogenetic analyses were done on specimens of Hyla marginata and on three populations of H. semiguttata differing in morphology and in the physical parameters of their advertisement call, as well as in individuals of Hyla sp. (aff. semiguttata). All specimens had 2n=24 chromosomes with a morphology very similar to that of other 24-chromosome Hyla species. Hyla semiguttata and H. marginata show...

Five new species of the feather mite genus Protolichus Trouessart, 1884 (Astigmata, Pterolichidae) are described from parrots of the subfamily Loriinae (Psittaciformes: Psittacidae): Protolichus ornatus sp. n. from Trichoglossus ornatus (Linnaeus, 1758), P. lorinus sp. n. from Lorius lory (Linnaeus, 1758), P. placentis sp. n. from Charmosyna placentis (Temminck, 1835), P. pulchellae sp. n. from...

A new enarmoniine genus, Sirindhornia, n. gen., is described based on the type species, Sirindhornia pulchella, n. sp., and three additional new species: Sirindhornia chaipattana, n. sp., Sirindhornia curvicosta, n. sp., and Sirindhornia bifida, n. sp., all from Thailand. A fifth species represented only by a single female is morphologically characterized but not formally described. Sirindhorni...

To determine the taxonomic identities and the systematic positions of some collections of Lindsaea sect. Synaphlebium (Lindsaeaceae) from Papua New Guinea, we conducted morphological comparisons and phylogenetic analyses on the whole section. A total of 22 morphological characters were selected and coded for each of all known taxa in L. sect. Synaphlebium, and were analyzed using maximum parsim...

Chromosome counts and karyotype information from 41 populations of 20 species and 6 varieties of Nicotianeae (Solanaceae) from South America belonging to Bouchetia Dunal (x 5 8), Fabiana Ruiz & Pav. (x 5 9), Leptoglossis Benth. (x 5 10), Nierembergia Ruiz & Pav. (x 5 8, 9), and Petunia Juss. (x 5 7, 9) are given, including first reports from 14 taxa: F. densa Rémy, N. ericoides Miers, and P. pa...

Microvelia pulchella, a semiaquatic predatory bug widely distributed in the Neotropics, holds great potential as biocontrol agent against disease-vector mosquitoes and pests paddy rice fields. Moreover, insects belonging to genus have served valuable model organisms for ecological behavioural research. Considering this, our study aimed establish an enhanced laboratory rearing protocol M. pulche...
