03EBFC02FFC95225FF74FF07FC6BF2CA.taxon	diagnosis	Diagnosis. Thryssocypris wongrati differs from all other species of Thryssocypris by having the origin of the dorsal fin behind the origin of the anal fin, 37 – 40 lateral-line scales, 16 circumpeduncular scales, and a dark spot at the base of the caudal fin. It is distinguished from T. smaragdinus in having the origin of the dorsal fin behind (vs. over or in front of) the origin of the anal fin and 16 (vs. 15) circumpeduncular scales, and from T. tonlesapensis and T. ornithosoma in having 37 – 40 (vs. 42 – 46) lateral-line scales and 39 – 41 (vs. 43 – 45) vertebrae. It further differs from T. ornithosoma by having a dark spot at the base of the caudal fin.	en	Grudpan, Chaiwut, Grudpan, Jarungjit (2012): Thryssocypris wongrati, a new anchovy-like cyprinid (Cypriniformes) from the Chao Phraya basin, Thailand.

03EBFC02FFC95225FF74FF07FC6BF2CA.taxon	description	Description. Meristic and morphometric characters are given in Tables 1 – 4. Body elongate and compressed (Figs. 1, 2). Head length 17.8 – 25.0 % SL. Snout conical, length 25.4 – 34.5 % HL (Table 4). Mouth terminal; maxilla extending well beyond anterior margin of eye (Fig. 3). Scales thin, deciduous; 37 – 40 lateral-line scales (Table 2), 23 – 25 predorsal scales, 16 circumpeduncular scales (Table 1). Dorsal-fin rays 9 – 10; anal-fin rays 14 – 16; pectoralfin rays 11 – 12; pelvic-fin rays 7 – 9. Anal and dorsal fins closer to caudal fin than to head. Origin of anal fin in front of origin of dorsal fin. Caudal fin deeply forked, rounded tips (Fig. 1). Total vertebrae 39 – 41 (Table 3). Color. In life, T. wongrati has a clear yellow body with a wide metallic silver stripe along the side (Fig. 1), a black spot on the caudal-fin base and black on the proximal portion of the medial caudal-fin rays (Fig. 2). All fins are transparent. In 10 % formalin, the body is dark brown.	en	Grudpan, Chaiwut, Grudpan, Jarungjit (2012): Thryssocypris wongrati, a new anchovy-like cyprinid (Cypriniformes) from the Chao Phraya basin, Thailand.

03EBFC02FFC95225FF74FF07FC6BF2CA.taxon	distribution	Distribution. Thryssocypris wongrati occupies the lower part of the Chao Phraya Basin where it has been recorded from irrigation canals in Sing-Buri up to the most northern part of the basin in Nan River, Phitsanulok (Fig. 4). In the upper part of Chao Phraya basin it is found in floodplain habitats (Jutagate et al. 2011), irrigation canals, and the river mainstem.	en	Grudpan, Chaiwut, Grudpan, Jarungjit (2012): Thryssocypris wongrati, a new anchovy-like cyprinid (Cypriniformes) from the Chao Phraya basin, Thailand.

03EBFC02FFC95225FF74FF07FC6BF2CA.taxon	biology_ecology	Ecology. Most specimens of the new species were collected by large seines with small mesh (2 mm) from open water in the Chao Phraya River mainstem. Some specimens were captured in current in irrigation canals. Schools of this species were observed at the surface of the water, swimming very fast with other species such as Clupeiodes borneensis, Rasbora spp., Barilius koratensis, Paralaubuca spp. and Discherodontus halei.	en	Grudpan, Chaiwut, Grudpan, Jarungjit (2012): Thryssocypris wongrati, a new anchovy-like cyprinid (Cypriniformes) from the Chao Phraya basin, Thailand.
