Etymology: Nannocharax: Latin, nannus = small + Greek, charax = a marine fish without identification (Ref. 45335);  luapulae: Specific name, luapulae, is named after the Luapula River, from which the holotype was collected (Ref. 129519).

Short description เครื่องมือที่ใช้ในการแยกชนิดสัตว์,สิ่งมีชีวิตออกจากกัน | สัณฐานวิทยา | ความยาวต่างๆ

เงี่ยงครีบหลัง (รวม) : 0; ก้านครีบอ่อนที่หาง (รวม) : 12 - 13; เงี่ยงครีบก้น: 0; ก้านครีบอ่อนที่ก้น: 8; สัตว์มีกระดูกสันหลัง: 39. Diagnosis: Nannocharax luapulae can be distinguished from all its congeners by the following unique combination of characters: its body colouration, which consist of 8 to 10 vertically ovoid or rounded black blotches that overlie a longitudinal mid-lateral black stripe vs. largely unpigmented body with only a black spot at the base of the caudal fin in N. hastatus, N. maculicauda and N. ocellicauda, six or seven rounded, well-spaced, mid-lateral black spots in N. gracilis, 17 black bars in N. fasciolaris, a broad black longitudinal band running on flanks along two rows of scales in N. latifasciatus, or a thin black lateral band covering only the lateral line scales, extending from snout to median rays of caudal fin in N. taenia; a completely pored lateral line vs. incompletely pored in N. angolensis, N. dageti, N. lineostriatus, N. machadoi, N. minutus, N. monardi, N. multifasciatus, N. rubensteini, N. uniocellatus and N. wittei; 49-55 lateral line scales vs. 38-40 scales in N. altus, 40-45 scales in N. ansorgii, 37-40 scales in N. brevis, 38-42 scales in N. fasciatus, 37-43 scales in N. hadros, 42 scales in N. hollyi, 45-48 scales in N. macropterus, 36-37 scales in N. micros, 36 scales in N. ogoensis, 36-40 scales in N. parvus, 38-43 scales in N. procatopus, 38 scales in N. pteron, 46-48 scales in N. reidi, 46-48 scales in N. signifer, 38-39 scales in N. schoutedeni, 43-44 scales in N. seyboldi, 38-44 scales in N. usongo and 39-43 scales in N. zebra; and a dorsal-fin origin that is situated anterior, 1-2 lateral line scales, to the pelvic-fin origin vs. origin situated well behind the pelvic-fin origin in N. lineomaculatus, N. rubrolabiatus, or at the same level in N. elongatus, N. intermedius, N. niloticus and N. occidentalis (Ref. 129519). Nannocharax luapulae is most similar to N. chochamandai but can be distinguished from it by a low number of branched soft fin rays in dorsal and anal fins, 9-10 and 5 vs. 11-12 and 8-9; a high number of lateral ine scales, 49-55 vs. 41-46; a short pectoral fin, 18.3-20.6% of standard length, not reaching the pelvic-fin insertion but extending to the level of the anterior dorsal-fin base origin, vs. 21.6-28.4% of standard length, reaching the pelvic-fin insertion and the level of about the middle of the dorsal-fin base; a short pelvic fin, 20.0-22.9% of standard length, not reaching the anal-fin insertion but extending to about mid-level of the dorsal-adipose fin distance, vs. 24.3-30.6% of standard length, reaching the anal-fin insertion and the level of the last one fourth of the dorsal-adipose fin distance; and a short anal fin, 13.6-15.1% of standard length vs. 15.6-19.0% (Ref. 129519).
