Figure 22. Acutiramus bipunctatus sp. nov. Male: (A) adult; (B) rostrum (ventral, * “lens”); (C) anterior cephalosome (dorsal); (D, E) 
antennule; (F) caudal ramus (detail). Scale bar: A = 0.34 mm. B, C = 0.15 mm. D, F = 0.06 mm. E = 0.08 mm. 
3V2 times width), medial and lateral edges without setules, 
dorsal surface with feint reticulation, a and fj setae not 
close, (3 seta half way down ramus, terminal setae plain, T1 
small, recessed at lateral comer, T2 small, T3 very small and 
delicate, T3 lies extremely close to T2 (on many specimens 
T2 and T3 appear to be absent, but this is probably due to the 
P5 limb rubbing against the posterior border of the caudal 
ramus and breaking off the setae), posterior border slightly 
concave with fine setules. No plumulose setae on antennule. 
Stmcture and setation of mouth parts and ambulatory limbs 
typical of family. Antenna exopod with five plumulose setae 
and one plumulose spinous seta (Fig. 20C), endopod segment 
2 with three lateral setae, geniculate setae with plain terminal 
portion, comb-like claw length of shortest geniculate 
seta. Mandible (Fig. 20A) without setules on anterior lobe 
of palp or molar process. Maxillule (Fig. 20D) with single 
seta on exopod. Maxilla (Fig. 201) and maxilliped (Fig. 
20B) as shown in figures. No area of denticulate setules 
on PI endopod (Fig. 20G). Serrulate spinous seta on P2 
endopod segment 3 shorter than endopod (0.8:1) (Fig. 21C).
