Lampanyctus pusillus 



(Johnson, 1890) 



Fig. 183 — Lampanyctus pusillus, 34.5 mm. From Nafpaktitis and Nafpaktitis 



(1969, p. 54, fig. 66). 



Description 



D. 12-13; A. 14-15: P. 13-14; AO 5 (4) -h 5-6, total 10 (9-11); gill rakers 3+1-1-8 (9), total 

 12(13). 



AOa but slightly curved; the space between first 2 AOa notably wider than these between 

 the rest. Prc^ distinctly before vertical from Prc:,. Caudal luminous glands small and weakly 

 formed, with 2 to 4 scales in supracaudal and 3 to 5 in infracaudal glands. 



Size: To about 40 mm. 



Least depth of capture: To 70 m at night. 



Distribution: In the eastern Pacific, it is known only from off Chile (Bussing, 1965; Crad- 

 dock and Mead, 1970) between about 29° and 34° S, 73° and 93° W. It is also known from the 

 southern Indian and North and South Atlantic Oceans. 

 Discussion 



This species is superficially similar to both L. alatus and L. australis but is readily 

 separable by the absence of a luminous scale at the base of the adipose fin and by the low 

 position of VLO, about midway between base of pelvic fin and lateral line.
