Abstract


Four populations of Calophya spp. (Hemiptera: Calophyidae) col­lected in Brazil were characterized using molecular and morphologi­cal methods. Examination of adults revealed the presence of 2 mor­photypes, which were identified as C. latiforceps and C. terebinthifolii. However, morphological examination of 5th instar nymphs detected differences within C. latiforceps, with a population from Ubu, Espírito Santo, being distinct from the other 2 populations. Molecular charac­terization of the mitochondrial CO1 gene supported the presence of a new species of Calophya.

 

Sumario

Se caracterizaron cuatro poblaciones de Calophya spp. (Hemipte­ra: Calophyidae) recolectadas en Brasil usando métodos moleculares y morfológicos. El examen de los adultos reveló la presencia de 2 mor­fotipos que se identificaron como C. latiforceps y C. terebinthifolii. Sin embargo, el examen morfológico de las ninfas del quinto estadio de­tectó diferencias dentro de C. latiforceps, con una población de Ubu, Espirito Santos de ser distinta de las otras dos poblaciones. La caracte­rización molecular del gen mitocondrial CO1 apoyó la presencia de una nueva especie de Calophya.
