Paroxystoglossa mourella , new species

Diagnosis

P. mourella n.sp. is entirely green and have orthogonal epistomal angle. This is species can be distinguished from other species from jocasta group by the faint metallic coloration in scape, the elongate shape of head and the fine punctures on terga. The male of P. mourella n.sp. can be distinguished by short body pubescence, the not swollen tibia and lesser prominent tubercles on fourth and fifth sterna.

Variation

Color variation on terga is known among females from Serra do Cipó (Minas Gerais).Most of females (about 80%) have mostly green discs sometimes with bluish or amber shades, especially on second and third terga. Some females have subtle to conspicuous cupreous reflections. None female have entirely red terga. A continuous size variation is evidenced (intertegular distance from 1.45 mm to 1.875 mm), but it is not associate with the color variation .
