Published online at www.senckenberg.de/vertebrate­zoology on 13.x.2017. Abstract Channa shingon, new species, is described from small mountainous rivulets associated with the Irrawaddy drainage in western Yunnan Province, China. Its maximum SL of about 100 mm makes it the smallest pelvic-fin bearing dwarf snakehead. Further specific characters are lateral head length 27 – 30 % SL; interorbital width 33 – 35 % HL; 25 – 27 anal-fin rays; 44 – 45 lateral-line scales; 4 – 5 scale rows between dorsal-fin origin and lateral line; 8 – 9 scale rows between lateral line and anal-fin origin; 1 mandibular scale; 43 – 44 vertebrae; in- feromesial process of parasphenoid very shallow and straight; dorsal profile conspicuously bulging in front of dorsal fin; juveniles without ocellus-like mark on posterior part of dorsal fin; and a pectoral-fin pattern of 3– 4 broad gray to black bands alternating with cream to white interspaces, bands increasingly wide towards distal edge of the fin, interspaces equally wide as bands or narrower. Key words Channa; new species; Irrawaddy; Salween; taxonomy. Introduction Dwarf snakeheads are a common element of Southeast BRITZ (2008). The complex comprises taxa with and Asia’s freshwater ichthyofauna.

Berbagai jenis tumbuhan obat di Indonesia sudah diteliti dan dieksplorasi peluangnya untuk dijadikan bahan obat ataupun nutrasetikal. Namun kekayaan keanekaragaman hayati Indonesia untuk obat dan nutrasetikal bukan hanya dari tumbuhan. tetapi juga dari hewan, jamur, mikroba, dan biota laut. Walaupun tidak sebanyak tumbuhan obat, tetapi pemanfaatan hewan dalam pengobatan tradisional juga sudah dikenal sejak zaman dahulu. Di beberapa daerah di Indonesia dan Malaysia sudah lama dikenal dan digunakan beberapa jenis hewan untuk meningkatkan kesehatan, salah satu di antaranya adalah ikan gabus. Ikan gabus dikenal sebagai makanan untuk mempercepat penyembuhan luka, terutama bagi anak-anak yang baru dikhitan dan ibu-ibu sehabis melahirkan. Pemberian daging ikan gabus bagi anak-anak yang baru dikhitan dan ibu- ibu sehabs melahirkan diyakini akan meningkatkan stamina, mengurangi rasa sakit, dan mempercepat kesembuhan luka. Rasa daging ikan gabus yang lezat juga akan meningkatkan nafsu makan sehingga akan menambah vitalitas. Beberapa hasil penelitian yang dilakukan dalam sepuluh tahun belakangan ini mengungkapkan bahwa daging ikan gabus mengandung protein, terutama albumin yang tinggi. Ikan gabus juga mengandung Zn (mineral seng) dalam jumlah cukup tinggi.

It is distinguished from all its congeners by a greenish-grey dorsum, pale brown to black pectoral fin with 2-3 inconspicuous semicircular bands, a series of 7-9 obliquely-arranged, saddle-like, dark olive to grey oblique streaks on green background on upper half of the body, 42-45 pored lateral-line scales, 12-13 branched caudal rays, 6-7 pre-dorsal scales, 43 vertebrae, two rows of teeth on the lower jaw, an outer row of numerous minute slender, pointed teeth and single inner row of large uniform sized teeth without any large canine like teeth on the anterior fourth of the lower jaw. Phylogenetically C. royi sp. nov. is closely related to C. harcourtbutleri, with a genetic distance (K2-P) of 2.4-2.8%, but morphologically differs in having greater inter-orbital width, fewer pelvic-fin rays (5 vs.
