1. Molecular validation of anthropophilic Phlebotominae sandflies (Diptera: Psychodidae) in Central Panama
Six Phlebotominae sand fly species are incriminated as biological vectors of human pathogens in Panama, but molecular corroboration is still needed. We aim at confirming the identity of Phlebotominae species documented as anthropophilic in Panama. Adult sandflies were collected from August 2010 to February 2012 in Central Panama using CDC light traps. Specie

2. Whole-genome duplication and hemoglobin differentiation traits between allopatric populations of Brazilian Odontophrynus americanus species complex (Amphibia, Anura)
Abstract Two allopatric populations of Brazilian diploid and tetraploid Odontophrynus americanus species complex, both from São Paulo state, had their blood hemoglobin biochemically analyzed. In addition, these specimens were cytogenetically characterized. Biochemical characterization of hemoglobin expression showed a distinct banding pattern between the al

3. Diversity and conservation status of Aegla spp. (Anomura, Aeglidae): an update
Abstract The speciose genus Aegla Leach, 1820 is the only valid extant genus of the anomuran family Aeglidae, bearing 83 known species. This diversity may be even greater since there is some evidence for cryptic speciation. The genus is endemic to southern South America, occurring in freshwater habitats. We assessed the conservation status of 82 species of A

4. Cryptic species of Paracoccidioides brasiliensis: impact on paracoccidioidomycosis immunodiagnosis
We aimed to evaluate whether the occurrence of cryptic species of Paracoccidioides brasiliensis, S1, PS2, PS3 and Paracoccidioides lutzii, has implications in the immunodiagnosis of paracoccidioidomycosis (PCM). Small quantities of the antigen gp43 were found in culture filtrates of P. lutzii strains and this molecule appeared to be more variable within P. l

5. Estudo filogeográfico de Chiropsalmus cf. quadrumanus (Cnidaria: Cubozoa) na Costa Brasileira / Phylogeographic study of Chiropsalmus cf. quadrumanus (Cnidaria: Cubozoa) in the Brazilian Coast
Os Cubozoa são animais de águas tropicais e subtropicais ao redor do mundo. A cubomedusa Chiropsalmus cf. quadrumanus (Cubozoa: Chiropsalmidae) habita na costa Atlântica americana entre os 35°N e 27°S, uma área com barreiras putativas que poderiam impedir a distribuição contínua de C. cf. quadrumanus, tornando-se um modelo interessante para estudos

6. Molecular divergence in the timeless and cpr genes among three sympatric cryptic species of the Anopheles triannulatus complex
Anopheles triannulatus s.l. is a malaria vector with a wide geographic distribution, ranging from Argentina-Nicaragua and Trinidad. Here we analysed sequences of two genes, timeless and cpr, to assess the genetic variability and divergence among three sympatric cryptic species of this complex from Salobra, central-western Brazil. The timeless gene sequences

7. Copulatory courtship song in Lutzomyia migonei (Diptera: Psychodidae)
Lutzomyia migonei is a vector of leishmaniasis with a wide distribution in South America, which could favour population differentiation and speciation. Cryptic species of the Lutzomyia longipalpis complex, the widely distributed sand fly vector of visceral leishmaniasis in Latin America, have previously been shown to display distinct copulation songs. We fou

8. Inferências carioevolutivas sobre grupos crípticos de peixes marinhos e estuarinos
Cytogenetic studies have been revealing a great diversity not detected, until then, in several families of fishes. Many of these groups, especially those that exhibit great diversity, like Perciformes and Siluriformes, possess species with difficult morphologic characterization, called cryptic species, commonly detected through karyotypic analyses, which rev

9. Sexual selection and speciation in field crickets
Recent theoretical work has shown that sexual selection may cause speciation under a much wider range of conditions than previously supposed. There are, however, no empirical studies capable of simultaneously evaluating several key predictions that contrast this with other speciation models. We present data on male pulse rates and female phonotactic res

10. Molecular evidence of cryptic speciation in planktonic foraminifers and their relation to oceanic provinces
The fossil record of planktonic foraminifers is a key source of data on the biodiversity and evolution of marine plankton. One of the most distinctive foraminiferal taxa, Orbulina universa, widely used as a stratigraphic and paleoclimatic index, has always been regarded as a single species. Here we present a phylogenetic analysis of Orbulina small subunit rD

11. Pseudo-cryptic speciation in coccolithophores
Coccolithophores are a group of calcifying unicellular algae that constitute a major fraction of oceanic primary productivity, play an important role in the global carbon cycle, and are key biostratigraphic marker fossils. Their taxonomy is primarily based on the morphology of the minute calcite plates, or coccoliths, covering the cell. These are diverse

12. Cryptic speciation and recombination in the aflatoxin-producing fungus Aspergillus flavus
Aspergillus flavus, like approximately one–third of ascomycete fungi, is thought to be cosmopolitan and clonal because it has uniform asexual morphology. A. flavus produces aflatoxin on nuts, grains, and cotton, and assumptions about its life history are being used to develop strategies for its biological control. We tested the assumptions of clonality and
