簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 6 - 7; 臀棘: 1; 臀鰭軟條: 4; 脊椎骨: 33 - 34. Distinguished from all other species of Crossoloricaria by having more teeth (4-8 premaxillary and 8-11 mandibular teeth); more coalescing plates (17-20); maxillary barbel longer (68-109 % HL), reaching middle or proximal third of pectoral fin; barbels of lower lip more developed (16-27% HL); interorbital width greater (16-21% HL); and first ray of dorsal, pectoral and pelvic fins produced beyond branched fin rays. Furthermore, it is distinguished from C. rhami by these osteological features: tip of first dorsal-fin pterygiophore passes between paired neural spines of 8th centrum and contacts posterior border of transverse process of 7th centrum; pectoral fin reaches anterior half of pelvic fin; pelvic skeleton with ischiac process of basipterygia elongated, longer than in C. rhami; and last pterygiophore of anal fin bears a bifid posterior process, ending at the middle of haemal spine of 18th centrum.
與所有的其他種的 Crossoloricaria 藉著具有更多的齒區分了;(4-8 上頜骨前的與 8-11個下顎齒) 多合併碟;(17-20) 上頜骨觸鬚更長的 (68-109% HL), 達到中央或近端的胸鰭中的第三; 下唇更多發展的 (16-27% HL) 的觸鬚; 眼間骨寬度比較大的 (16-21% HL); 而且第一個鰭條背部的, 胸鰭與腹鰭生產超過分枝的鰭條。 此外，它被這些骨學的特徵與 C. rhami 區分: 第一背鰭支鰭骨的頂端在第 8個椎體與第 7個椎體的橫跨突起的接觸在一起後緣的成對髓棘之間經過; 胸鰭達到前半部的腹鰭; 有著被延長的 basipterygia 的坐骨突起的腹鰭骨骼, 長度超過在 C. rhami 中; 而且臀鰭的最後支鰭骨有被終點在第 18個椎體的脈棘的中央的一個兩裂的在後部的突起。
Occurs in the main river and major tributaries, always over sandy beaches. Stomach contents include larvae of aquatic insects, small seeds and debris. The holotype (male, 11.59 cm SL) carried 53 fertilized eggs (3.2-3.4 mm diameter) on its lips and another specimen was carrying 31 unfertilized eggs (3.1-3.4 mm diameter).
出現於主要的河與主要的支流, 總是在沙灘之上。 胃內含物包括水生昆蟲幼生，小的種子與殘礫。 holotype(雄魚,11.59 公分 SL) 孕有 53 個受精卵 (3.2-3.4 mm 直徑) 在它的唇，而且另一件標本正在攜帶 31個未受精的卵 (3.1-3.4 mm 直徑) 。
