“…Soma et al. () stated that it is not certain whether gorals diversified earlier than serows or the reverse, but Schaller () suggested that serows (Mid‐Late Pliocene) may be more recent than gorals (Early‐Mid Pliocene). Our data support Schaller's remark: the goral clade separates earlier than the serow clade from their common ancestor (Fig.…”

Taxonomy is partly a subjective matter, but it is instrumental for ecological, behavioural and especially conservation studies. According to the International Union for Conservation of Nature, goat‐antelopes (Bovidae: Rupicaprini tribe) number 13 species, 62% of which are ‘Threatened’ or ‘Near Threatened’ with extinction. During recent decades, the number of extant species of goat‐antelopes – especially in endemic Asian genera (goral: six species Naemorhedus spp.; serow: seven species Capricornis spp.) – has been inflated. We have revised the taxonomy and phylogeny of the gorals and serows, for the first time using the total mitochondrial genome of all taxa. We confirm the existence of three goral and four serow species. We can find no justification for the existence of Naemorhedus griseus (Chinese goral), Naemorhedus bedfordi (Himalayan goral) and Naemorhedus evansi (Burmese goral), which should be pooled together within Naemorhedus goral (brown goral). Two species of mainland serow are also recognised: Capricornis rubidus (red serow) and Capricornis sumatraensis (Sumatran serow). Capricornis rubidus and Naemorhedus baileyi (red goral) are the forms more closely related to the common Pliocenic, still‐unknown ancestor. Among serows, Capricornis crispus is sister to all remaining species. Capricornis rubidus and Capricornis swinhoei (Formosan serow) are sister species, probably the remnants of an older radiation of mainland serows.

The molecular evidence of phylogenetic status regarding the Formosan serow (Capricornis swinhoei) is not robust and little is known about the genetic diversity of the Sumatran serow (Capricornis sumatraensis), which partly is due to the hardness in sample collection. Here we determined the sequences of the complete mitochondrial DNA control region (1,014 bp) of 19 Sumatran-serow individuals. Nine new haplotypes were defined based on 78 variable sites. Combined analysis with other 32 haplotypes downloaded from the public database, including 1 Sumatran-serow, 11 Formosan-serow and 20 Japanese-serow (Capricornis crispus) haplotypes, a relatively high level of nucleotide diversity was first observed in Sumatran serow (π = 0.0249). By comparative analysis with structural consensus sequences from other mammals, we have identified central, left and right domains and depicted the putative functional structure, including extend termination associated sequences and conserve sequence blocks, in mtDNA control region. The alignment of mtDNA control region revealed that both Sumatran and Japanese serow have two tandem repeats (TRs), but three TRs in Formosan serow. Phylogenetic analyses revealed that the Formosan serow is distinct species with the Japanese serow, but a sister group with the Sumatran serow. The divergence time estimated among three serow species revealed that Pleistocene climate changes and the uplift of Qinghai-Tibetan plateau might play an important role in the genetic differentiation of the serows. These results mainly provide the convinced evidence on the genetic relationship between three serow species.

New filarial nematode from Japanese serows (Naemorhedus crispus: Bovidae) close to parasites from elephants

et al. 2006

Summary :A new onchocercid species, Loxodontofilaria caprini n. sp. (Filarioidea: Nematoda), found in subcutaneous tissues of 37 (33 %) of 112 serows (Naemorhedus crispus) examined in Japan, is described. The female worm had the characteristics of Loxodontofilaria, e.g., the large body size, well-developed esophagus with a shallow buccal cavity, and the long tail with three caudal lappets. The male worm of the new species, which was first described in the genus, had unequal length of spicules, 10 pairs of pre-and post-caudal papillae, and three terminal caudal lappets. Deirids were present in both sexes. Among four species of the genus Loxodontofilaria: one from the hippopotamus and three from the Elepantidae, L. caprini n. sp. appears close to L. asiatica Bain, Baker & Chabaud, 1982, a subcutaneous parasite of Elephas indicus in Myanmar (Burma). However, L. caprini n. sp. is distinct from L. asiatica in that the Japanese female worm has an esophagus half as long and the microfilariae also half as long with a coiled posterior. The microfilariae were found in the skin of serows. The new parasite appears to clearly illustrate a major event in the evolution of onchocercids: the host-switching. This might have occurred on the Eurasian continent, where elephantids and the lineage of rupicaprines diversified during the Pliocene-Pleistocene, or in Japan, into which some of these hosts migrated.
