“…In order to elucidate the origin of the various butterfly eye designs, we have initiated a study on the Glacial Apollo butterfly, Parnassius glacialis, a 'living fossil' species in the family Papilionidae [18]. The Apollo belongs to the Parnassini, the oldest tribe in the subfamily Parnassiinae, which diverged from the other papilionid subfamilies in the Cretaceous period [19] and rapidly radiated in the late Tertiary period [20].…”

The eye of the Glacial Apollo butterfly, Parnassius glacialis, a 'living fossil' species of the family Papilionidae, contains three types of spectrally heterogeneous ommatidia. Electron microscopy reveals that the Apollo rhabdom is tiered. The distal tier is composed exclusively of photoreceptors expressing opsins of ultraviolet or blue-absorbing visual pigments, and the proximal tier consists of photoreceptors expressing opsins of green or red-absorbing visual pigments. This organization is unique because the distal tier of other known butterflies contains two green-sensitive photoreceptors, which probably function in improving spatial and/or motion vision. Interspecific comparison suggests that the Apollo rhabdom retains an ancestral tiered pattern with some modification to enhance its colour vision towards the long-wavelength region of the spectrum.

“…The first duplication of the ancestral L opsin gene happened before the subfamily Parnassiinae diverged from the other papilionid subfamilies, probably in the Cretaceous period (Grimaldi and Engel, 2005;Omoto et al, 2009), giving rise to the L2 and L3 opsins. The peak absorption of L3 opsin was shifted to a longer wavelength.…”

SUMMARYRecent studies on butterflies have indicated that their colour vision system is almost species specific. To address the question of how this remarkable diversity evolved, we investigated the eyes of the glacial Apollo, Parnassius glacialis, a living fossil species belonging to the family Papilionidae. We identified four opsins in the Parnassius eyes -an ultraviolet-(PgUV), a blue-(PgB), and two long wavelength (PgL2, PgL3)-absorbing types -and localized their mRNAs within the retina. We thus found ommatidial heterogeneity and a clear dorso-ventral regionalization of the eye. The dorsal region consists of three basic types of ommatidia that are similar to those found in other insects, indicating that this dorsal region retains the ancestral state. In the ventral region, we identified two novel phenomena: co-expression of the opsins of the UV-and B-absorbing type in a subset of photoreceptors, and subfunctionalization of long-wavelength receptors in the distal tier as a result of differential expression of the PgL2 and PgL3 mRNAs. Interestingly, butterflies from the closely related genus Papilio (Papilionidae) have at least three long-wavelength opsins, L1-L3. The present study indicates that the duplication of L2 and L3 occurred before the Papilio lineage diverged from the rest, whereas L1 was produced from L3 in the Papilio lineage.

“…Retrieved sequences were automatically aligned by the MAFFT program (Katoh and Standley, 2013), and carefully checked by eye. The impact of the partition model on both tree inference and divergence time estimation was discussed in detail in our previous studies (Omoto et al, 2009;Wu et al, 2014). The unlinked partition model (Pupko et al, 2002) was applied to take account of the different tempo and mode of nucleotide substitutions among genes and codon positions.…”

Cretaceous origin of giant rhinoceros beetles (Dynastini; Coleoptera) and correlation of their evolution with the Pangean breakup

The giant rhinoceros beetles (Dynastini, Scarabaeidae, Coleoptera) are distributed in tropical and temperate regions in Asia, America and Africa. Recent molecular phylogenetic studies have revealed that the giant rhinoceros beetles can be divided into three clades representing Asia, America and Africa. Although a correlation between their evolution and the continental drift during the Pangean breakup was suggested, there is no accurate divergence time estimation among the three clades based on molecular data. Moreover, there is a long chronological gap between the timing of the Pangean breakup (Cretaceous: 110-148 Ma) and the emergence of the oldest fossil record (Oligocene: 33 Ma). In this study, we estimated their divergence times based on molecular data, using several combinations of fossil calibration sets, and obtained robust estimates. The inter-continental divergence events among the clades were estimated to have occurred about 99 Ma (Asian clade and others) and 78 Ma (American clade and African clade), both of which are after the Pangean breakup. These estimates suggest their inter-continental divergences occurred by overseas sweepstakes dispersal, rather than by vicariances of the population caused by the Pangean breakup.
