tubercles, somewhat subserrate in dorsal outline; 10 tubercles (13 on 
left dactyl) in ventromesial row, extending to base of distal two-fifths 
of finger; single tubercle proximoventral to first in ventromesial row 
(on left, similar tubercle ventral to first); dorsomesial row with 6 
tubercles (7 on left); single small, rounded tubercle dorsal to base 
of first one in dorsomesial row. Ventral surface of dactyl rounded, 
with sparse punctations bearing setae. Opposable surface of dactyl 
with mat of plumose setae at base, and moderate excision extending 
from first to fourth tubercles; margin with row of 9 knoblike tubercles; 
denticles in 3 to 4 rows, extending along distal two-thirds of finger. 
Fixed finger of propodus subtriangular in cross-section, with well 
developed, fairly broad middorsal ridge, which essentially glabrous, 
but with sparse punctations on proximal one-fifth; ridge mesially and 
laterally subtended by groove containing row of setiferous punctations 
extending nearly to base of tip, and flanked each side by somewhat 
abbreviated ridge, ridges merging at about base of distal one-fourth 
of finger; rudimentary dorsolateral ridge in proximal half of finger, 
extending to about midlength; lateral margin proximally costate. Opposable 
surface of fixed finger with setae at base, margin with row of 8 knoblike 
tubercles extending to about midlength; subconical tubercle at base 
of distal one-third of finger, ventral to denticles, which in 3 to 4 
continuous rows. 
Right carpus (Fig. 1J) 1.5 times as long as wide, 1.7 times as 
long as deep, ratio width to depth 1.1; carpus punctate dorsally, with 
oblique median sulcus, several squamous tubercles on dorsomesial surface; 
mesial surface sparsely punctate, with long procurved spine at midlength, 
flanked proximally by smaller, somewhat acute tubercle near mesial 
base of podomere; second long, acute spine situated proximomesial 
to articular eminence; ventromesial surface with sparse, setiferous puncta- 
tions and several very small tubercles; ventral surface with large disto- 
median spine and larger spine on distal end of lateral articular condyle; 
lateral surface of carpus with scattered setiferous punctations. 
Right merus 2.1 times as long as deep; dorsal surface with 2 
long subdistal spines; ventromesial ridge with acute distal spine and 
5 additional ones, ventrolateral ridge with acute distal spine and 4 
additional ones, none on distolateral articular condyle; lateral and mesial 
surfaces of merus essentially glabrous. Right ischium with row of 3 
low, subacute tubercles on ventral ridge, distal to suture line; small 
hooklike sufflamen adjacent to large articular condyle of coxa. 
Palm of chela and carpus of second pereiopod with row of long 
setae on dorsomesial and ventromesial surfaces, no stiff setae on mesial 
margin; other podomeres with rows of long setae on ventral or ventromesial
