[Ichthyology • 2012] ปลาตะพัดสีนาก | Scleropages inscriptus | Inscribed Asian Arowana • a new fish species from the Tananthayi or Tenasserim River basin, Malay Peninsula of Myanmar (Osteoglossidae: Osteoglossiformes)

Abstract

Scleropages inscriptus, a new species of bony-tongue fishes, is described from the Tenasserim or Tananthayi River basin on the Indian Ocean coast of peninsular Myanmar. It differs from the previously known Southeast Asian and Australian members of the genus in having the bones of the circumorbital and opercular series and all or most of the scales on the sides of the body densely covered with complex maze-like markings. In morphology and in meristic and morphometric characters it is closer to the other Asian species of Scleropages, S. formosus, than to S. leichhardti or S. jardinii, the two species currently recognized from the Australian Region; it is therefore referred to the subgenus Delsmania Fowler 1934 (type species S. formosus).

[Ichthyology • 1986] Danionella translucida • a new genus and species of cyprinid fish from Burma, one of the Smallest Living Vertebrates

Abstract

Danionella translucida, a new genus and species of danioin cyprinid fishes, is described from Burma. Females are mature at 10–11 mm standard length, and the largest known specimen is only 12 mm. Ripe eggs are few in number and relatively large, 0.4–0.6 mm in diameter. Adults are scaleless and largely transparent, with a complex pattern of large melanophores on the ventral surface of the abdomen. Specializations observed in skeletal preparations include the danioin notch in the medial surface of the mandibles; a large maxillo-mandibulary cartilage; a cartilage (epibranchial 5?) uniting the branchial arches 4 and 5; pharyngeal bones with a single row of 4 tricuspid teeth; and pectoral, pelvic, and caudal fins with fewer rays than reported or observed in any other members of the family Cyprinidae.

[Ichthyology • 2007] Celestichthys margaritatus | Celestial Pearl Danio • a new genus and species of colourful minute Cyprinid fish (Pisces: Cypriniformes) from the Salween basin, northeast of Inle Lake, northern Myanmar

Celestichthys margaritatus | Celestial Pearl Danio

ABSTRACT

 Celestichthys margaritatus, a new genus and species of Danioinae, is described from a rapidly developing locality in the Salween basin about 70–80 km northeast of Inle Lake in northern Myanmar. Males and females are strikingly colouful. It is apparently most closely related to two danioins endemic to Inle, Microrasbora rubescens and “Microrasbora” erythromicron. The latter species may be congeneric with the new species. The new genus is identified as a danioin by specializations on its lower jaw and its numerous anal fin rays. The colouration, while highly distinctive, seems also to be characteristically danioin. The danioin notch (Roberts, 1986; Fang, 2003) is reduced or absent, but the danioin mandibular flap and bony knob (defined herein) are present. The anal fin has iii81/2–101/2 rays. In addition to its distinctive body spots and barred fins the new fish is distinguished from other species of danioins by the following combination of characters: snout and mouth extremely short; premaxillary with an elongate and very slender ascending process; mandible foreshortened; body deep, with rounded dorsal and anal fins; modal vertebral count 15+16=31; caudal fin moderately rather than deeply forked; principal caudal fin rays 9/8; scales vertically ovoid; and pharyngeal teeth conical, in three rows

KEY WORDS. – Hopong; principal caudal fin rays; danioin mandibular notch, knob, and pad; captive breeding.

Etymology. – The generic name Celestichthys, gender masculine, is from the Latin caelestis, “heavenly”; and Greek ichthys, masculine, “fish”. The species or trivial name margaritatus is Latin for “adorned with pearls.” Used as a noun in apposition.
