Results for “longitudinal”

Following the key of Romand (1992) this species can be told apart from congeners by the following combination of characters: adult size > 40 mm SL; large, dark, transverse bars and some reddish-brown pigmentation on flanks; longitudinal bands more-or-less defined; longitudinal bands composed of small red spots; caudal-fin subquadrangular caudal fin; 11-13 anal-fin rays; 16-17 dorsal-fin rays; 7-8 anal-fin rays located anterior to dorsal-fin origin.

This species is a member of the putative A. nasutus group of closely-related species within the genus alongside A. nasutus, A. maculipinna and A. isalineae. These are characterised by possession of two dark, longitudinal stripes, one running from the tip of the snout to the base and the other from the posterior edge of the lower maxilla to the underside of the caudal peduncle.

This species is a member of the putative A. nasutus group of closely-related species within the genus alongside A. nasutus, A. maculipinna and A. isalineae. These are all characterised by possession of two dark, longitudinal stripes, one running from the tip of the snout to the base and the other from the posterior edge of the lower maxilla to the underside of the caudal peduncle.

This species was considered synonymous with the Indochinese congener C. micropeltes for over a century before being revalidated in 2011. Like in C. micropeltes colour pattern varies depending on the age of the fish. Juveniles possess two longitudinal black stripes on the head and body with the are...

This species can be distinguished from congeners inhabiting the Red River basin in Yunnan province, China, by the following combination of characters: no barbels; 46-52 lateral line scales; 16 circumpeduncular scales; pharyngeal teeth in 3 rows, 2.4.5-5.4.2; snout rounded, no secondary rostrum, no longitudinal...

G. salweenica can be distinguished from other congeners inhabiting the Salween watershed by the following combinatuion of characters: body brownish; presence of a trilobed proboscis on the snout; snout blunt; a series of black spots at the base of the central dorsal-fin rays; presence of longitudinal stripes on the posterior portion of the body; a dark marking at the tip of the upper (and lower in some specimens) caudal-fin lobe; body depth 22.4-25.3 % SL.

This species can be distinguished from congeners in Southeast Asia and China by the following combination of characters: plain brown body and fins, sometimes with 6-8 narrow, faintly distinct, longitudinal stripes; snout triangular in dorsal view, with small tubercules and without transverse groove...

H. borealis is a member of the putative ‘H. heterorhabdus-group’ of closely-related species within the genus as proposed by Géry (1977). There are around 15 members characterised by a 'longitudinal pattern' consisting of a thin, usu...

It can be distinguished from congeners by the following combination of characters: 61-68 scales in the lateral series; a small, well-defined, sometimes ocellated black spot on the shoulder and another in the centre of the caudal peduncle; body without longitudinal stripes formed by spots on scales; caudal fin uniformly dusky or colourless, lobes without stripes or black margins.

L. siamensis can be distinguished from congeners by the following combination of characters: 39-42 scales in the lateral series; shoulder spot usually absent, but sometimes well-defined; body with longitudinal stripes formed by a spot on each scale; dorsal fin with dusky median stripe and no red coloration; caudal fin dusky, sometimes with reddish coloration, but no well-defined stripes; 20-23 circumpeduncular scales...

It can be distinguished from other members of the genus by the following characters: dark longitudinal stripe on body, extending from eye to caudal peduncle; scattered tubercles present on lower jaw; 14½-16½ branched anal-fin rays; pelvic-fin long, reaching beyond anus.

This species is uncommon in the aquarium trade which is a little surprising given its huge natural range. Different populations can vary in colour pattern to an extent though all share the defining aspects given by Hamilton, comprising a diffuse yellow-golden marking on the operculum plus a dark spot on the caudal peduncle. The latter is usually surrounded by a variably-sized golden-yellow margin, and the dorsal-fin often contains irregular dark spots and streaks, these sometimes forming a longitudinal band.

This species may not yet have appeared in the ornamental trade but it has been collected by a few individuals. It can be told apart from related species from Taiwan by possessing 30-32 longitudinal (lateral) scales vs. 32-39 in other species, and 6-8 scale rows between the origin of the first dorsal-fin and upper pectoral-fin base vs. 9-15 in other species.

This species has been in the aquarium trade since 2010 and is sold under several names including 'Chinese vermilion goby', 'Zhou's scarlet goby', 'scarlet goby', and 'flame goby'. It can be told apart from congeners by the following combination of characters: second dorsal-fin rays I, 8-9; anal-fin rays I, 7-8; pectoral-fin rays 16-18; longitudinal scale series 29-31; predorsal scales 10-12; vertebral count 10+16=26.
