Feihyla vittiger (Boulenger, 1897) comb. nov.

Javan Jelly-nest Frog

(Figs. 1–2, 4, 6; Tables 1–2)

Original name and description. Ixalus vittiger Boulenger, 1897 . Boulenger G.A. 1897. Descriptions of new Malay frogs. Annals and Magazine of Natural History, 19: 106–108. Type. Holotype, BMNH 1947.2.7.58. Type locality. “Pengalengan”, West Java, Indonesia. Current status of specific name. Valid name as Feihyla vittiger (Boulenger, 1897) comb. nov.

Taxonomic remarks. This species is morphologically close to Feihyla inexpectata and the same is also confirmed phylogenetically based on the new sequence data included in our study (Fig. 1). Furthermore, its reproductive mode (eggs deposited in jelly nests) (Fig. 6) is possibly also a phenotypic synapomorphy for the genus Feihyla (Li et al. 2009; Hertwig et al. 2013; present study). Hence, we propose that Chiromantis vittiger (Boulenger, 1897) be transferred to genus Feihyla .

Diagnosis. Small to medium-sized adults (male SVL 24–27 mm, female SVL 23–26 mm) with a slender body; snout rounded to truncate in dorsal view, and truncate in lateral view; dorsal skin shagreened to sparsely granular, with or without scattered spinules; dorsal colouration variable, ranging from light lemon yellow to light or dark brown, with or without a reddish tinge; dorsum with or without contrasting dark spots and minute speckles, even within the same population; upper arm, loreal, canthal and tympanic regions, lateral surfaces of abdomen, and anterior and posterior parts of thigh, non-pigmented (flesh coloured); a white streak starting from the snout tip and extending along the lateral surfaces up to the groin, separates the dorsal and lateral body colouration; the first two fingers opposed to the others; foot webbing moderate, up to the second tubercle on either side of toe IV.

Genetic divergence. Phylogenetically, F. vittiger is closely related to members of the Feihyla vittiger group (Fig. 1). For the 16S mitochondrial gene, it differs by average uncorrected genetic distances of: 9.5–9.9% from F. inexpectata and 12.6–12.8% from F. kajau . For interspecific genetic distances with other congeners, see Table 2.

Distribution. Feihyla vittiger is currently known only from the Indonesian island of Java: Bogor, Pengalengan, and Mount Halimun-Salak National Park in West Java, and Banwumas in Central Java.
