“…As most taxa in the subfamily Pyrginae seem to rely on chemical recognition (Hernández‐Roldán et al . ), the composition of CHCs could be the proximate mechanism involved in the emergence of reproductive barriers also in the case of S. rosae . This hypothesis is supported by the fact that the cuticular hydrocarbon profile of S. rosae is the most differentiated in the group.…”

Discovering cryptic species in well-studied areas and taxonomic groups can have profound implications in understanding eco-evolutionary processes and in nature conservation because such groups often involve research models and act as flagship taxa for nature management. In this study, we use an array of techniques to study the butterflies in the Spialia sertorius species group (Lepidoptera, Hesperiidae). The integration of genetic, chemical, cytogenetic, morphological, ecological and microbiological data indicates that the sertorius species complex includes at least five species that differentiated during the last three million years. As a result, we propose the restitution of the species status for two taxa often treated as subspecies, Spialia ali (Oberthür, 1881) stat. rest. and Spialia therapne (Rambur, 1832) stat. rest., and describe a new cryptic species Spialia rosae Hernández-Roldán, Dapporto, Dincă, Vicente & Vila sp. nov. Spialia sertorius (Hoffmannsegg, 1804) and S. rosae are sympatric and synmorphic, but show constant differences in mitochondrial DNA, chemical profiles and ecology, suggesting that S. rosae represents a case of ecological speciation involving larval host plant and altitudinal shift, and apparently associated with Wolbachia infection. This study exemplifies how a multidisciplinary approach can reveal elusive cases of hidden diversity.

“…A recent study on the genus Pyrgus , which belongs to the same subfamily as Spialia (Pyrginae), showed that chemical divergence among populations tends to be rather weak, but it rapidly rises and attains a plateau when speciation takes place, as expected if they represent species‐specific recognition cues (Hernández‐Roldán et al . ).…”

“…Skipper butterflies (Lepidoptera: Hesperiidae) include approximately 4,000 species in 567 genera worldwide 1 and account for a fifth of the world’s butterfly fauna 2 . Despite considerable efforts in recent years 3 – 5 , the higher-level phylogenetic relationships within the family Hesperiidae are still unsatisfactorily resolved.…”

The systematic positions of two hesperiid genera, Apostictopterus and Barca (Lepidoptera: Hesperiidae), remain ambiguous. We sequenced and annotated the two mitogenomes of Apostictopterus fuliginosus and Barca bicolor and inferred the phylogenetic positions of the two genera within the Hesperiidae based on the available mitogenomes. The lengths of the two circular mitogenomes of A. fuliginosus and B. bicolor are 15,417 and 15,574 base pairs (bp), respectively. These two mitogenomes show similar AT skew, GC skew, codon usage and nucleotide bias of AT: the GC skew of the two species is negative, and the AT skew of A. fuliginosus is negative, while the AT skew of B. bicolor is slightly positive. The largest intergenic spacer is located at the same position between trnQ and ND2 in A. fuliginosus (73 bp) and B. bicolor (72 bp). Thirteen protein-coding genes (PCGs) start with ATN codons except for COI, which starts with CGA. The control regions of both mitogenomes possess a long tandem repeat, which is 30 bp long in A. fuliginosus, and 18 bp in B. bicolor. Bayesian inference and maximum likelihood methods were employed to infer the phylogenetic relationships, which suggested that A. fuliginosus and B. bicolor belong in the subfamily Hesperiinae.

“…Relationships among and within butterfly families have been largely studied by phylogenetic analyses of DNA sequence data (Campbell, Brower & Pierce, 2000; Caterino et al, 2001; Braby, Vila & Pierce, 2006; Nazari, Zakharov & Sperling, 2007; Wahlberg et al, 2009; Simonsen et al, 2011; Heikkilä et al, 2012; Wahlberg et al, 2014; Espeland et al, 2015). Yet, the higher-level relationships among skipper butterflies, with more than 4,000 species in about 567 genera (Warren, Ogawa & Brower, 2008) and representing a fifth of the world’s butterfly fauna (Hernández-Roldán et al, 2014), are still unsatisfactorily resolved.…”

Despite multiple attempts to infer the higher-level phylogenetic relationships of skipper butterflies (Family Hesperiidae), uncertainties in the deep clade relationships persist. The most recent phylogenetic analysis included fewer than 30% of known genera and data from three gene markers. Here we reconstruct the higher-level relationships with a rich sampling of ten nuclear and mitochondrial markers (7,726 bp) from 270 genera and find two distinct but equally plausible topologies among subfamilies at the base of the tree. In one set of analyses, the nuclear markers suggest two contrasting topologies, one of which is supported by the mitochondrial dataset. However, another set of analyses suggests mito-nuclear conflict as the reason for topological incongruence. Neither topology is strongly supported, and we conclude that there is insufficient phylogenetic evidence in the molecular dataset to resolve these relationships. Nevertheless, taking morphological characters into consideration, we suggest that one of the topologies is more likely.
