DOI: 10.1371/journal.pone.0246466

Abstract

Badis kaladanensis, a new percoid fish is described from the Kaladan basin of Mizoram, northeast India. It belongs to the Badis badis species group but can be easily distinguished from its congeners, except from B. kanabos and B. tuivaiei, in having a dark blotch on the dorsal fin between the base of 3rd to 5th spines. It is further distinguished from B. kanabos in having more scales in lateral row (27–30 vs. 25–26), more circumpeduncular scale rows (18–20 vs. 16–17) and smaller eye (7.5–8.9% SL vs. 9.5–12.7); and from B. tuivaiei in having fewer vertebrae (28–29 vs. 30–31) and more rakers on the first gill arch (9 vs. 6–8). The analysis of the mitochondrial DNA (coi and cytb) revealed the distinctness of B. kaladanensis from all other Badis species with the interspecific distance ranges from 5.4–20.4%. (coi) and 5.1–26.3% (cytb).

Badis kaladanensis sp. nov.

Diagnosis: Badis kaladanensis is distinguished from its congeners in having the following combination of characters: a post nuchal hump, a conspicuous dark blotch covering superficial part of cleithrum above pectoral-fin base, a dark anterior dorsal-fin blotch between 3rd to 5th spines (consistently present in live and preserved specimens), 27–30 scales in lateral row, 18–20 circumpeduncular scale rows, 28–29 vertebrae, 9 rakers on the first gill arch and lacking a dark blotch on the dorsolateral aspect of caudal peduncle.

Etymology. The species is named after the River drainage, the Kaladan River. An adjective.

Abstract

Dario neela, is described from a small tributary stream of the Kabini River in northern Kerala, India. It can be distinguished from congeners by the male colouration in life, which shows wide rims of iridescent blue in all median fins and the pelvic fin. It is further distinguished from all species of Dario, except D. urops by the number of abdominal vertebrae (14 vs. 11–13), and from all Dario species except D. urops and D. huli by the presence of a conspicuous black blotch on the caudal-fin base. Dario neela is distinguished from D. urops by the absence of the horizontal suborbital stripe and presence of a series of up to eight black bars on the body; and from D. huli by 27–28 vertebrae and 27 scales in a lateral row and the absence of teeth from hypobranchial 3. Dario neela is genetically divergent from both Western Ghats congeners in the mitochondrial CO1 gene, showing an uncorrected p-distance of 5.9% with D. urops and 13.1% to D. huli.

Etymology. The species name neela is derived from the Malayalam word mnoe, ‘Nīla’, for blue and alludes to the striking iridescent blue colour of males. A noun in apposition.

[Ichthyology • 2016] Badis pancharatnaensis • A New Percoid Fish Species (Teleostei: Badidae) from Brahmaputra River drainage, Assam, India

Badis pancharatnaensis 

Basumatary, Choudhury, Baishya, Sarma & Vishwanath, 2016 

Abstract

Badis pancharatnaensis, a new percomorph, is described from the Brahmaputra River drainage of Assam, India. It is distinguished from its congeners by having the following combination of characters: a conspicuous black blotch on the superficial part of cleithrum; pointed soft dorsal, anal, and pelvic fins, the 2nd soft ray of pelvic-fin reaching slightly beyond the vent; 13 ‒ 14 pectoral-fin rays; circumpeduncular scales 14 ‒ 17; body depth 28.2 ‒ 33.8% of SL; interorbital distance 7.1 ‒ 9.4% of SL; and 28 number of vertebrae.

Key words:  Badidae, Badis, taxonomy, new species, River Brahmaputra, Assam.

Fig. 5. Hasila Beel, type locality of Badis pancharatnaensis sp. nov. showing habitat. 

Diagnosis: Badis pancharatnaensis sp. nov. is distinct from all its congeners in having a combination of characters: presence of dark brownish black bars on sides; a series of dark blotches along middle of dorsal-fin; a prominent black blotch on the superficial part of cleithrum; elongate median caudal blotch with a posterior bar surrounding the caudal-fin base; pointed pelvic-fin reaching beyond vent in both the sexes; pointed soft dorsal and anal-fin; 28.2 ‒ 33.8% SL body depth; 7.1 ‒ 9.4% SL interorbital distance; 14 ‒ 17 circumpeduncular scales; 31 ‒ 33 lateral scale rows; 6 ‒ 8 number of gill rakers; and 28 (15+13) number of vertebrae

Distribution and habitat. Presently the species is known from Hasila Beel – a riverine wetland of Brahmaputra drainage at Goalpara district, Assam, India (Fig. 4). The type locality is a low lying wetland having dense macrophytic vegetation well connected with the River Brahmaputra and often flooded by the river water; that shows high degree of rise and fall of water level depending on seasonal climatic variations (Fig. 5).

The associated fish fauna caught along with the species were Amblypharyngodon mola, Anabas testudineus, Channa gachua, Lepidocephalichthys guntea, Mastacembelus armatus, Macrognathus pancalus, Puntius sophore and Trichogaster fasciata which commonly occur in the region. 

 Etymology. The species is named after the historical place called ‘Pancharatna’ in Goalpara district of Assam, India.

[Ichthyology • 2015] Badis britzi • A New Percomorph Fish (Teleostei: Badidae) from the Western Ghats of India

Badis britzi

Dahanukar, Kumar, Katwate & Raghavan, 2015

Abstract

Badis britzi, the first species of the genus endemic to southern India, is described from the Nagodi tributary of the west-flowing Sharavati River in Karnataka. It is distinguished from congeners by a combination of characters including a slender body, 21–24 pored lateral-line scales and a striking colour pattern consisting of 11 bars and a mosaic of black and red pigmentation on the side of the body including the end of caudal peduncle, and the absence of cleithral, opercular, or caudal-peduncle blotches, or an ocellus on the caudal-fin base. Badis triocellus Khynriam & Sen is considered a junior synonym of B. singenensis Geetakumari & Kadu.

[Ichthyology • 2015] Dario huli • A New Species of badid (Teleostei: Percomorpha: Badidae) from Karnataka, southern India

Dario huli Britz & Ali, 2015

DOI: 10.11646/zootaxa.3911.1.9

Abstract

Dario huli, new species, is described from a small tributary stream of the Tunga River in southern Karnataka, India. It can be distinguished from all its congeners except D. urops by the presence of a conspicuous black caudal-fin blotch and by anterior dorsal-fin lappets in males not being produced beyond fin spines. It is readily distinguished from Dario urops by the absence of the horizontal suborbital stripe (vs. presence), the presence of a series of up to eight black bars on the body (vs. 2–3 black bars restricted to caudal peduncle), 25 scales in a lateral row (vs. 28), 3–5 tubed lateral-line scales (vs. tubed lateral-line scales completely absent), 13+13=26 vertebrae (vs. 14+14–15=28-29), and the presence of teeth on hypobranchial 3 (vs. absence of teeth).
