Phrygionis incolorata - Incolorata Moth (Prout, 1910)
Lepidoptera: Bombycina: Geometroidea: Geometridae: Ennominae: Baptini
31th of October, 2018 announcement. I have never done this before in my posts but this time it will be different - Brazil is undergoing a process that may decide the fate of the entire planet as its lungs are located here. The new president of Brazil wants to merge the Ministry of Agriculture with the Ministry of the Environment, two antagonical sectors. If this happens, the impacts will be great worldwide.

Phrygionis incolorata is a species of moth in the order Lepidoptera, subdivision Bombycina, superfamily Geometroidea, family Geometridae, subfamily Ennominae and tribe Baptini. Based on what is seen on the antennae and description below this is a female, but no assurance is given.
MORPHOLOGY AND A BIT OF THE ANATOMY FOR ACADEMICS:
Wingspan lies between 16mm - 18mm. Base of forewings made of a yellow metallic transverse band outlined by a black border. Postbasal area containing a longer yellow metallic transverse band outlined in black and the costa segment has a black spot and a yellow stripe going towards the base. Discal area next to the costa contains a black, medium dot and a yellow metallic stripe connecting the previous yellow band with the next in the postdiscal segment. Postdiscal segment has a large and long yellow metallic transverse band outlined in black that has continuity with the hindwings until the costa. Marginal area of the forewings with a fine yellow metallic band outlined in black on both sides with continuity until the apex of the hindwings and broken in the tornus by an ocellus. The overall coloring of the moth is brown. The genus has apomorphy in the male genitalia which is prominent, usually forked and a posterior extension of the juxta. The female genitalia has a signum as a dentate disc, hollow or not, or signum-absent. Antennae bipectinate in males and simple filiform in females. Front of the head is very narrow in males, but this information needs confirmation. Usually, members of the genus itself have three metallic-edged transverse bands on the forewings. The postdiscal band is more distinct and follows Oudeman's Principle as described. The hindwings has one or two small dark spots at the outer margin near or at vein M3. Forewings lack fovea and veins Sc and R1 meet to form a secondary cell. These spots may present themselves as partially metallic. The outer margin of the hindwings tend to be sharply angled or rounded. Tympanal cavity contains a well-developed sac extending from the wall. 6th tergite of the male abdomen may contain hair scale tufts, absent in a few species.
I could find close to no information on these moths. According to a source provided below, the genus is distributed as such:
Mexico; Guatemala; Belize; Honduras (Scoble); Costa Rica; Panama; Bahamas; Cuba; Jamaica; Dominican Republic; Puerto Rico; USA Virgin I. (Scoble); Guadeloupe (Herbulot, http://www.inra.fr/Internet/Produits/PAPILLON/geometri/texteng/geometri.htm); Dominica; Martinique; Trinidad; Colombia; Venezuela; Guyana; Surinam; French Guyana; Ecuador (Scoble); Peru; Brazil; Bolivia; Paraguay (Scoble); Argentina; Uruguay (Scoble); [USA: Texas (Scoble), and Florida].
Host plants MAY include Rampanea umberallis (Myrsinaceae) but this definitely needs confirmation.
Neotropical Ennominae members are significant components of tropical forests. The caterpillars feed on leaves of trees and shrubs. Attracted to lights, only the cycle of P. polita was described: http://livros01.livrosgratis.com.br/cp036346.pdf
Phrygionis incolorata's behavior, lifecycle, feeding habits and reproduction remains to be known and recorded. What is known, however, is that P. incolorata are of nocturnal activity.
The genus itself bears close resemblance to Pityeja and Opisthoxia, and must not be mistaken.
