Typhlamia bella one female (K 41435), ANT XXII-3, PS 67/154-9, 62°31.47'– 62° 31.36'S, 64°39.45'– 64° 39.25'W, depth 3804–3808 m, 30 Mar 2005.   
 Diagnosis: Carapace as long as wide. Pereopod-1 carpus seta just half of propodus length; pereopod-2 merus and carpus with setae reaching end of following article. Uropod exopod as long as endopod proximal article.   
 Etymology: Bella (Lat.) = pretty, neat. The name reflects the author’s personal impression of the habitus of the animal.   
 Description: Non-ovigerous female (Fig. 52A,B). Body length 3.6 mm, 7.8 times as long as broad. Carapace smooth, rounded laterally, as long as wide, 13% of body length, rostrum blunt. Pereonites smooth, slightly rounded lateral margins; pereonite-6 trapezoidal; pereonite-1 is 0.7 times length of carapace; pereonites 2, 3 and 6 of similar size; pereonite-2 a little longer than pereonite-1; pereonite-4 a little longer than wide; pereonite-5 as long as wide. Pleon 20% of body length, a little shorter than pereonites 5 and 6 combined; pleonites 1–5 similar in size; pleotelson semi-rounded; caudal projection weak.   
Antennule (Fig. 53A): Twice as long as carapace; article-1 seven times as long as wide, with five simple setae and five pinnate setae arranged in groups on inner and outer margin; article-2 with two distal setae; article-3 2.5 times as long as article-2, over ten times as long as wide, tipped by four long simple setae.  
Antenna (Fig. 53B): Article-2 three times as long as article-3; article-4 twice as long as article-5, with three simple and two pinnate setae distally; article-5 with one distal setae; article-6 tipped by four setae.  
 Mouth parts: Labrum (Fig. 53C) covered by minute setae. Mandible (Figs 53D,E) stout; molar process (Fig. 53 D’) well-developed, with crenulated distal margin; lacinia mobilis well-developed, crenulated. Maxillule (Fig. 53F) endite with eight spiniform setae distally; palp lost during dissection. Maxilla (Fig. 53G) semitriangular. Maxilliped (Fig. 53I) bases fused little longer than wide; each with simple seta reaching far over endites; endite armed with two setae and two tubercles on distal margin; palp four-articled: article-1 naked; article-2 wedge-shaped, with three setae on inner margin; article-3 trapezoidal, with three bipinnate and one simple setae on inner margin; article-4 slender (1.5 times as long as wide), with one simple seta on outer margin and five bipinnate terminal setae. Epignath lost during dissection. Labium (Fig. 53H) bilobed, outer corner of inner lobe and outer lobe with minute setae.   
Cheliped (Fig. 54A): Basis 1.3 times as long as wide; merus wedge-shaped with one short seta ventrally; carpus about 2.5 times as long as broad with two dorsal setae and with two long setae ventrally; propodus and fixed finger about as long carpus, about three times as long as wide; fixed finger with three setae on inner margin and two setae on ventral margin.  
Pereopod-1 (Fig. 54B): Coxa with seta; basis a little shorter than merus, carpus and propodus combined; ischium with simple seta; merus slightly shorter than carpus, with simple seta distally; carpus with four short and two long (longer than half of propodus) setae distally; propodus 1.2 times as long as carpus, with one ventral and one dorsal setae subdistally; dactylus almost as long as unguis, with seta reaching end of unguis, together 0.6 times length of propodus.  
Pereopod-2 (Fig. 54C): Coxa with seta; basis slightly longer than merus and carpus combined; ischium with simple seta; merus a little shorter than carpus, with one short and long (as long as carpus) seta distally; carpus with two short, two long and two spiniform setae distally; propodus slightly longer than carpus, with one spiniform seta ventrally and two subdistal simple setae on dorsal margin; dactylus almost as long as unguis, with short seta.  
Pereopod-3 broken.  
Pereopod-4 (Fig. 54D): Clinging type; basis with two pinnate setae; ischium with two setae ventrally; merus with one spiniform seta and one short simple seta; carpus with two spiniform setae, small prickly tubercle, and one seta distally; propodus six times as long as wide, with two spiniform ventro-distal setae and with distal setae just reaching end of dactylus; unguis broken.  
Pereopod-5 (Fig. 54F): Similar to pereopod-4; unguis with bifid tip.  
Pereopod-6 (Fig. 54E): Similar to pereopod-4, but propodus with three distal setae, little shorter than dactylus..  
Pleopods 1–5 (Fig. 54G): Basal article naked; exopod with twelve plumose setae on outer margin andone seta on inner margin; endopod with 20 plumose setae on outer margin. Gap between most proximal seta and the other setae in both rami.  
Uropod (Fig. 54H): Endopod two-articled; proximal article 1.5 times length of distal article, with one distal seta; distal article tipped by three simple setae. Exopod one-articled, as long as endopod proximal article; tipped by one short and one long setae.  
 Distribution: The species occurs in the Antarctic Ocean: Eastern part of Weddell Sea, at depths of 4392- 4385 m, and in the vicinity of the South Shetland Islands at depths of 3804–3808 m.
