Etymology: Neolamprologus: Greek, neos = new + Greek,lampros = torch + Greek, lagos = hare (Ref. 45335); timidus: The species name is a Latin adjective meaning shy, with reference to the elusive or shy behaviour of this species in the natural habitat (Ref. 95525).

简单描述
型态特徵 | 形态测量图
背棘 (总数): 19 - 21; 背的软条 (总数): 7-8; 臀棘 0; 臀鳍软条: 12. Diagnosis: Neolamprologus timidus is distinguished from the most similar species, Neolamprologus furcifer, in scaled cheek vs. naked; first soft ray of pelvic fin longer than second vs. second ray longer than first; pectoral fin reaching beyond base of first anal-fin spine vs. shorter; absence of dark spot at caudal-fin base in adults vs. presence; longer head, 34.2-35.5% of standard length vs. 31.2-33.8%; longer pectoral fin, 29.3-353.7% of standard length vs. 23.4-31.3%; and pectoral fin in life light yellow or transparent vs. orange (Ref. 95525). It is distinguished from all other lamprologin species except Lepidiolamprologus profundicola, Neolamprologus ventralis and N. leloupi in fully scaled cheek vs. scales absent from cheek or present only posterodorsally (Ref. 95525). It is distinguished from Neolamprologus leloupi by the shape of the caudal fin, which is deeply emarginate, with long streamers vs. posterior margin concave, streamers absent; colour overall dark, with indistinct darker horizontal stripes vs. overall light, with faint brown zigzag lines along side; 49-62 scales in a longitudinal row vs. about 30; dorsal-fin rays XIX-XXI,7-8 vs. XVII,9; and gill rakers 11-13 vs. 6 (Ref. 95525). It is distinguished from Neolamprologus ventralis by caudal-fin shape deeply emarginate, with long streamers vs. rounded, subtruncate or slightly emarginate with rounded lobes; colour overall dark with indistinct darker horizontal stripes vs. overall light, scales with light brown margins; unpaired fin dark, with few, indistinct spots vs. numerous light spots all over unpaired fins; and 49-62 scales in a longitudinal row vs. 34-37 (Ref. 95525). It is distinguished from Lepidiolamprologus profundicolaby caudal-fin shape deeply emarginate with long streamers vs. truncate or slightly emarginate; longer pectoral fin, reaching beyond base of first anal-fin spine vs. not reaching vent; single neurocranial lateral line foramen 0 vs. double; dermosphenotic absent vs. present; and labial cartilage not ossified vs. ossified (Ref. 95525).
This shy species is observed at depths varying from 2 to 40 m in a dark rocky biotope, and encountered in pairs defending a territory over a dark cave difficult to access; the territory was often located to a large rock or boulder, which, if large enough was inhabited also by other species like Neolamprologus furcifer and Julidochromis regani; almost always found upside down in cave with belly close to substrate (Ref. 95525).
