This study examines the tegminal coloration pattern and the morphometry of Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae) progeny of crosses between parents with differing wing patterns. Genetic studies were used to investigate whether the different coloration patterns of tegmina have resulted from speciation within the M. spectabilis clade. We crossed M. spectabilis with differing wing patterns to determine percentages of coloration standards of the tegmina and the biometry of the first generation (F1) progeny. DNA of specimens was extracted and analyzed. The results show that parental phenotype was a determining factor in the tegminal coloration pattern of offspring of generation F1. Slight variation exists in the specimens’ morphometry; no grouping trend is evident with regard to specimens with different tegminal coloration patterns. Based on the characteristics of the population analyzed herein, it seems that there has been no speciation of M. spectabilis. Resumo Avaliou-se o padrao de coloracao de asas e a morfometria da descendencia de cruzamentos entre pais com diferentes padroes de asas de Mahanarva spectabilis (Distant) (Hemiptera: Cercopidae). Estudos geneticos foram utilizados para investigar se os diferentes padroes de coloracao das asas resultaram de especiacao de M. spectabilis. Utilizou-se casais de M. spectabilis com diferentes padroes de asas para determinar as porcentagens dos padroes de coloracao das asas e a biometria da progenie de primeira geracao (F1). O DNA das amostras foi extraido e analisado. Os resultados mostraram que o fenotipo parental foi um fator determinante no padrao de coloracao das asas dos descendentes da geracao F1. Verificou-se pequena variacao na morfometria das amostras; nenhuma tendencia de agrupamento e evidente em amostras com diferentes padroes de coloracao de asas. Com base nas caracteristicas da populacao analisada, nao houve especiacao de M. spectabilis. Key Words: forage; speciation; spittlebug View this article in BioOne
