Preliminary identification of geographically distinct populations as belonging to the same species (N.paspalivorus) was based on their morphological similarity. However, laboratory studies recently conducted have shown large differences in feeding behaviors and biological characteristics among individuals collected from three geographic origins: Brazil (South America), Benin and Ghana (West Africa). As morphologically similar specimens do not necessary belong to the same species, we evaluated under laboratory conditions, reproductive compatibility between the specimens from three geographic locations to ascertain their conspecificity.Morphological measurements were also made to determine if there is a means of discriminating between them.Inter-population crosses showed complete reproductive isolation between the three geographic populations, but interpopulation discontinuities in morphometric characters were absent. These results indicate that the tested specimens are distinct biological entities despite morphological similarity. Further molecular genetic studies are therefore proposed, including screening for endosymbionts and assessment of genetic differentiation, to determine the cause of reproductive incompatibility and to clarify the taxonomic relationship between those populations.

Morphological, molecular and cross-breeding analysis of geographic populations of coconut-mite associated predatory mites identified as Neoseiulus baraki: evidence for cryptic species?

“…In addition to genetic differences observed, the cross-breeding experiments showed that populations studied represent distinct biological entities (Biological species, sensu Mayr 1940), as has been observed for several phytoseiid and phytophagous mite species (McMurtry et al 1976;Mahr and McMurtry 1979;Monetti and Croft 1997;Noronha and Moraes 2004;Klimov et al 2004;Famah Sourassou et al 2011). There are several explanations for the absence of offspring in crosses between populations.…”

The predatory mite Neoseiulus paspalivorus (Phytoseiidae) in Brazil: taxonomic status, reproductive compatibility and morphological and molecular variability

“…Famah Sourassou et al (2011) performed multivariate morphometric analysis and crossing experiments with three populations of N. paspalivorus (Benin, Ghana and Brazil) and concluded that the studied populations were different species, despite their morphological similarity. Famah Sourassou et al (2012) used multivariate morphometric analysis, molecular analyses and crossing experiments with populations of N. baraki from Benin, Tanzania and Brazil.…”

“…Diferenças biológicas têm sido observadas não apenas entre espécies claramente distintas, mas mesmo entre espécies muito próximas e entre populações distintas de uma mesma espécie (OKASSA et al, 2009;SOURASSOU et al, 2011).…”

“…A variação de parâmetros morfológicos entre populações de fitoseídeos tem sido citada na literatura (NORONHA; MORAES, 2002;OKASSA et al, 2009;SOURASSOU et al, 2011). Embora variações dessas características entre indivíduos de uma espécie de fitoseídeo sempre existam, o intervalo de variação de cada estrutura é usualmente desconhecida.…”

“…A frequente sobreposição parcial dos intervalos de variação das dimensões de cada estrutura considerada relevante na caracterização de espécies dificulta a correta identificação destas (OKASSA et al, 2009;SOURASSOU et al, 2011). Embora variações dessas características entre indivíduos de uma espécie de fitoseídeo sempre existam, o intervalo de variação de cada estrutura é pouco conhecido.…”
