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.
