Una nueva especie de Oregmopyga (Coccoidea, Eriococcidae) de Perú, descripción de estadios inmaduros

Abstract: IntroducciónDesde hace muchos años se encuentra en distintas zonas de la costa peruana, una cochinilla que afecta la vid. La primera observación de esta plaga fue realizada por Wille (1952), quien la cita como una especie del género Phenacoccus, probablemente aceris, indicando que ataca en forma importante los troncos de la vid en algunos valles vitícolas y en forma grave en Majes (Arequipa). El citado autor describe a las hembras adultas de color púrpura, y cubiertas con filamentos blancos de consistencia cer… Show more

“…El género Trionymus Berg, 1899 contiene 124 especies descriptas y distribuidas en todas las regiones biogeográficas, excepto la Antártica. En el Neotrópico solo se encuentran registradas siete especies del género: T. austrinus Granara de Willink, 2003, T. caricis McConnell, 1941, T. coronus Miller & McKenzie, 1971, T. nicotianacola Williams & Granara de Willink, 1992, T. petiolicola Morrison, 1922, T. radicicola Morrison, 1926y T. smithii Essig, 1910; para México se citan tres especies: T. caricis, T. coronus y T. smithii (Kosztarab, 1996;Arriola Padilla, 2012;García Morales et al, 2016). Este pobre registro quizás se deba a las escasas recolecciones realizadas en el área (Granara de Willink, 2003).…”

“…Future work on immature Puto should take note of this character to determine if it is a general feature across the family. In Eriococcidae, where adults have translucent pores, the translucent pores are also present in females of the final immature instar (second instar) (Granara de Willink & Díaz 2007, Miller & Stocks 2022. For at least some Pseudococcidae, translucent pores in third-instar females are absent from species where adult females have them (Wakgari & Giliomee 2004, 2005Waterworth et al 2012) though immatures are poorly known across Coccomorpha and this character state has probably not been considered in many descriptions.…”

“…One species in the complex, other than Ov. parvispinus, was described by Granara de Willink and Díaz (2007) as Oregmopyga peruviana and was distinguished by the lack of, or highly reduced number of, enlarged setae. It is treated here as a distinct species, i.e., Ov.…”

“…The justification for treating Oregmopyga as a junior synonym of Ovaticoccus, leading to this new combination, is provided in the "Notes" section that follows the generic description above. The adult female, second-instar male and female, and first-instar nymph of this species were described in detail by Granara de Willink and Díaz (2007) and information from that paper is not repeated here. We include a new description of the adult female from localities and hosts other than in the original description and include the species in keys to the various instars.…”
