简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 6-8; 臀棘 0; 臀鳍软条: 10 - 13; 脊椎骨: 24 - 26. Diagnosis: Lacustricola chobensis is distinguished from L. centralis, L. jobaerti, L. johnstoni, L. jubbi, L. katangae, L. macrurus, L. matthesi, L. mediolateralis, L. moeruensis, L. myaposae, L. nigrolateralis, and L. stiassnyae by the possession of banded dorsal, anal, and caudal fins in males, a conspicuous reticulate pattern on scale margins, and also by the possession of a pointed premaxilla ascending process, in which the premaxilla medial surface is slightly convex (Ref. 123968). It is distinguished from L. hutereaui by the possession of 10-13 anal-fin rays vs. 14-15; first dorsal-fin ray inserted in a vertical to the fourth or fifth anal-fin rays, vs. sixth anal-fin ray; first dorsal-fin proximal radial between 11th-12th vertebral neural spine, vs. 13th; absence of maxilla ventral sharp process, vs. presence; retroarticular about the same size as anguloarticular ventral process, vs. shorter; posteroventral extension on lachrymal, vs. rectangular, without posteroventral extension; infraorbital canal anterior portion open, with three neuromasts, vs. closed, with four pores; mandibular canal open, with two small neuromasts, vs. closed, with four pores; head neuromasts placed in shallow grooves or in the same level as head surface, vs. in deep grooves; posttemporal ventral arm not ossified, vs. ossified; cleithrum posterodorsal flap rounded, vs. sinous; and by hypural plate completely fused, vs. with a small gap, rarely fused (Ref. 123968). It is distinguished from L. petnehazyi by the presence of 10-12 anal-fin rays, vs. 14-16; first dorsal-fin ray inserted in a vertical to fourth or fifth anal-fin rays, vs. sixth to eight anal-fin rays; 22-24 scales on longitudinal line, mode 23, vs. 24-27, mode 26; 6-8 dorsal-fin rays, mode 7, vs. 8-9 dorsal-fin rays, mode 9 (Ref. 123968). It is distinguished from L. pygmaeus by the possession of 21-24 caudal-fin rays, vs. 26-30; an elliptical caudal fin in males, vs. rounded; chromatophores along whole mid-body line of flank, forming a conspicuous line, vs. inconspicuous; 6-8 dorsal-fin rays, vs. 10-12; first dorsal-fin ray inserted in a vertical to the fourth or fifth anal-fin rays, vs. second and third anal-fin ray; and by the absence of a concavity on quadrate posterior margin, vs. presence (Ref. 123968).
Found in swampy and riverine environments close to marginal vegetation (Ref. 123968).
