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 examined the relationship between landscape structure and composition, geographic ranges, microhabitat characteristics and the diversity of butterflies (Papilionidae, Nymphalidae, Pieridae, Hesperiidae, Lycaenidae) in an expanding urban landscape in the highlands of Chiapas, Mexico. Between 2001 and 2016, mountain wetlands, secondary forest, and agro-pasture land, have declined significantly in area covered due to increasing housing activities and expansion of roads and conversion of land for cattle activity. Cloud forest exhibited a minor positive expansion in area, mostly through forest regeneration. In total, we recorded 3630 individuals from 90 species at key sites spanning natural, semi-natural and urban areas. A rarefaction curve analysis for local richness indicated that mountain wetland sites recorded the highest butterfly diversity. Logistic regression analyses suggested that species with narrow geographic ranges could be associated to cloud-forest sites, and that species with relatively more widespread distributions in the Neotropics were more likely to be classified as occurring in mountain wetland habitats. This was confirmed by IndVal analyses from which we identified 39 butterfly species as potential reliable land-cover indicators. Furthermore, canonical correspondence analyses suggested significant associations for the values of butterfly abundance and microhabitat variables such as canopy cover, open areas, presence of grasses, bare soil or rocks. It is a matter of urgency that should put in place monitoring schemes to assess occupancy and change so we can assess changes in the status of butterfly species in rapidly-expanding urban landscapes in tropical Mexico.

Resumen en inglés

Fragmentation is the third cause of the biodiversity declination. Population genetic studies using Lepidoptera as the model species in the context of loss of habitat are scarce, particularly for tropical areas. We chose a widespread butterfly from Mexico as the model species to explore how changes of habitat characteristics (undisturbed forest, anthropogenic disturbances, and coastal areas), and climatic conditions affect genetic diversity and population structure. The Nymphalidae Eunica tatila is a common species in the Yucatan Peninsula considered to be a bio-indicator of undisturbed tropical forest, with migratory potential and a possible sex-biased dispersal. We genotyped 323 individuals collected in eight undisturbed areas, using four Inter Simple Sequence Repeats primers. Results show a high genetic diversity and no population structure. Temperature and shrub density present a positive and significant relationship with polymorphism values. Furthermore, our results show the positive effect of surrounding forest habitat on genetic diversity, confirming that E. tatila is a bio-indicator of undisturbed tropical forest. We found evidence of sex-biased dispersal. This paper represents one of the few studies on population genetics of tropical butterfly in a fragmented landscape and is, therefore, an important step in understanding the impact of habitat fragmentation on the risk of a butterflies' decline.

Resumen en inglés

Hybridization events are frequently demonstrated in natural butterfly populations. One interesting butterfly complex species is the Enantia jethys complex that has been studied for over a century; many debates exist regarding the species composition of this complex. Currently, three species that live sympatrically in the Gulf slope of Mexico (Enantia jethys, E. mazai, and E. albania) are recognized in this complex (based on morphological and molecular studies). Where these species live in sympatry, some cases of interspecific mating have been observed, suggesting hybridization events. Considering this, we employed a multilocus approach (analyses of mitochondrial and nuclear sequences: COI, RpS5, and Wg; and nuclear dominant markers: inter-simple sequence repeat (ISSRs) to study hybridization in sympatric populations from Veracruz, Mexico. Genetic diversity parameters were determined for all molecular markers, and species identification was assessed by different methods such as analyses of molecular variance (AMOVA), clustering, principal coordinate analysis (PCoA), gene flow, and PhiPT parameters. ISSR molecular markers were used for a more profound study of hybridization process. Although species of the Enantia jethys complex have a low dispersal capacity, we observed high genetic diversity, probably reflecting a high density of individuals locally. ISSR markers provided evidence of a contemporary hybridization process, detecting a high number of hybrids (from 17% to 53%) with significant differences in genetic diversity. Furthermore, a directional pattern of hybridization was observed from E. albania to other species. Phylogenetic study through DNA sequencing confirmed the existence of three clades corresponding to the three species previously recognized by morphological and molecular studies.

This study underlines the importance of assessing hybridization in evolutionary studies, by tracing the lineage separation process that leads to the origin of new species. Our research demonstrates that hybridization processes have a high occurrence in natural populations.
