308 U.S. NATIONAL MUSEUM BULLETIN 236 



Legs strongly developed, and very spinuous. The various details 

 appear clearly in figures 122a-c, 123a; the following points need special 

 mention. 



Legs 1 to 4 with 3-segmented exopodites and 2-segmented endop- 

 odites. Bases of all feet with fine external seta and rows of spinules 

 bordering insertion of exopodite and endopodite. 



Leg 1 (fig. 122a). Basis with strong spine near insertion of endop- 

 odite. 1st and 2nd segment of exopodite with very strong external 

 marginal spine. 3rd exopodal segment with 2 spines and 2 setae. 

 1st endopodal segment with brush-shaped internal seta. 2nd exop- 

 odal segment with strong, conical apical spine, and 2 internal, 

 spiniform setae. 



Legs 2 to 4 have the following setal formula: 



endopodite exopodite 



leg 2 1.311 0.1.023 



leg 3 1.221 0.1.123 



leg 4 1.121 0.1.123 



Leg 2. Internal seta on 1st endopodal segment spiniform. 3 spines 

 occur along external margin of 2nd endopodal segment (fig. 1226). 



Leg 3. Internal seta at 1st endopodal segment spiniform. 2nd 

 endopodal segment with 2 internal setae but with slight notch between 

 insertion of these setae that may have carried a third seta which is 

 absent, nevertheless, on both sides. External margin of that segment 

 with 3 spines (fig. 122c). 



Leg 4. Internal seta on 1st endopodal segment spiniform. 2 spines 

 occur at external border of segment 2 of endopodite (fig. 123a). 



Leg 5. Baso-endopodites of both sides fused, each side with 4 setae 

 and 2 haired (internal) spines. Exopodites spatulate, ovoid, slightly 

 longer than wide, reaching slightly beyond baso-endopodite, with 5 

 marginal setae. Exopodite and baso-endopodite with canaliculated 

 structure. External lobe lengthened, with fine seta. The actual 

 structure of leg 5 appears best in figure 1236. Genital field represented 

 in figure 121c?. 



Color greenish, strongly faded. No eye or pigmented spot visible. 



Adult male, total length 0.87 mm.; greatest diameter 0.15 mm.; 

 length of longest f ureal seta 0.41 mm. 



General shape of body as in female, cylindrical, with division be- 

 tween cephalo thorax and abdomen indistinctly marked (fig. 1216). 

 As in female, head and 1st thoracic somite fused and of same length; 

 4th thoracic somite longer. Rostrum as in female, sm-rounded by 

 hyaline membrane and with 2 fine hairs each placed in circular pit. 

 1st and 2nd abdominal somites separate; 1st fairly short. All ab- 

 dominal somites with distal hyaline lamella and some small, latero- 

 dorsal teeth on their distal portion, particularly visible in lateral 

 aspect.
