背棘 (总数) : 2. Several faint dark dorsal saddle marks on the posterior half of the body; pale intervening marks about the width of two scale rows; naked ventral surface of head and lower jaw (some with 1-3 scales beside articulation of lower jaw); dorsal anterior snout with naked triangular areas; naked below nostrils to suborbital ridge; large well-developed oval dermal window of light organ separated from anus by 2-3 rows of scales; lateral and medial processes of nasal bone not continuous (Ref. 26363). Resembles Caelorinchus maurofasciatus, C. mystax, C. bollonsi, C. cookianus, and C. fasciatus. Differs from C. mystax, C. bollonsi, and C. fasciatus in numbers of pyloric caeca (22-28 versus 111-115, 27-38, 12-23, respectively) in addition to other characters (Ref. 26363). C. parvifasciatus has similar numbers of pyloric caeca to C. maurofasciatus and C. cookianus but differs in having saddle markings only on the posterior half of the body (Ref. 26363).
Body shape (shape guide): elongated.
在身体的后半段上的一些模糊的深色背部的标志; 灰白的其间标志大约二鳞片列的宽度; 头部与下颌的裸露腹面;(一些具有在下颌的关节旁边的 1-3个鳞片) 背部的前面吻部有裸露的三角形的区域; 裸露的在到眶下的脊鼻孔之下; 发光器的大发展良好的椭圆形皮窗与 2-3 列的鳞片肛门分开了; 鼻骨的侧面与中间突起不是连续.(参考文献 26363) 与 摩洛哥腔吻鳕［Caelorinchus maurofasciatus］， C. mystax ， C. bollonsi ， C. cookianus 与 C. fasciatus 相似。 以及其他的特徵在幽门盲肠 (22-28 对 111-115,27-38,12-23, 分别地) 的数量中有别于 C. mystax ， C. bollonsi 与 C. fasciatus 。 (参考文献 26363) C. parvifasciatus 有对 C. maurofasciatus 与 C. cookianus 的幽门盲肠的相似数量但是只有在身体的后半段上不同之处为有鞍状斑纹.(参考文献 26363)
A benthic species found on the continental slope (Ref. 75154).
