Resumen en español

Se describe e ilustra el exocorion de Detritivora barnesi con el empleo de las técnicas de tinción de azul de metileno y el estereoscopio, así como del microscopio electrónico de barrido; los caracteres registrados se comparan con los de otros géneros de Riodinidae americanos. El exocorion de Detritivora barnesi es de una forma hemidiscal o cuasiesferoidal deprimida y exhibe una estructura en forma de ‘crochet’ en la región coriónica de transición; muestra retícula hexagonal regular de cuatro hileras, cuyos polígonos presentan proyecciones cilindriformes cortas en sus vértices. Estas características las comparten con Calephelis Grote & Robinson, considerado uno de los géneros más próximos a Detritivora Hall & Harvey. También comparte varios caracteres con el género Caria Hübner, además de la posición de los aerópilos/hidrópilos en el exocorion. No obstante, la trama reticular se asemeja con la del exocorion de Juditha, que pertenece a Lemoniadiina (Nymphidiini); aunque el grosor de las aristas difiere. Se sugiere una mayor exploración del exocorion de otras Riodinidae, con el fin de analizar su utilidad taxonómica y filogenética en esta familia.

Resumen en inglés

The exochorion of Detritivora barnesi is described and illustrated with the use of methylene blue staining and stereoscope, as well as scanning electron microscopy techniques; the registered characters are compared with those of other genera of American Riodinidae. The exochorion of Detritivora barnesi is depressed hemidiscal or quasi-spheroidal form, and exhibits a ‘crochet’ structure in the transitional chorionic region; it shows four-row regular hexagonal grid, whose polygons have short cylindrical projections at their vertices. These characteristics are shared with Calephelis Grote & Robinson, considered one of the closest genera to Detritivora Hall & Harvey. Also, it shares several characters with the genus Caria Hübner, plus the position of the aeropiles/hydropiles in the exochorion. However, the reticular grid resembles that of the exochorion of Juditha, which belongs to Lemoniadiina (Nymphidiini), although the thickness of the edges differs. Further exploration of the exochorion of other Riodinidae is suggested to analyze its taxonomic and phylogenetic utility in this family.

Resumen en inglés

We studied the chorionic morphology of six species of Hamadryas, and together with previous studies, we compared our results with previously published phylogenies for the genus. Samples were obtained from 19 females collected between 2013 and 2017 whose abdomens were sectioned and preserved for later dissection. Eggs were extracted from those dissections and used for the descriptions and illustrations of the chorion. The Hamadryas egg is of the globose type; it is quasi-spheroidal and has multiple polygonal grids with differentiation in specific zones/regions, and knolls with macrocells in their summits that arise in the apical third. These characteristics are very different from those found in the majority of Biblidinae and for those reported in the literature for Batesia and Panacea, which belong to the same subtribe as Hamadryas (Ageroniina, now Ageroniini). Chorionic characters support a previously suggested division of the genus (februa, feronia and laodamia groups) and they agree with the phylogenetic proposal based on morphological characters. Our study expands previous morphological work focused on this genus and compiles all the information available to date about the exochorion of Hamadryas, which now includes data for 10 species and that of Ectima thecla thecla, the putative sister group of Hamadryas.
