Figure 18. — Denligryps bifurcatus, new species (holotype female, allotype male): a, first 

 thoracic leg; b, second thoracic leg; c, third thoracic leg; {d, third thoracic leg exopodite 

 process of D. curius);e, fourth thoracic leg;/, portion of denticulated median terminal spine 

 of fourth thoracic leg. 



large, inwardly curved, bifurcate process at junction of protopodite 

 and exopodite. Process of exopodite of third thoracic leg of D. curtus 

 simple, not bifurcate (fig. 18c/). First segment of exopodite small, 

 flattened, second and third segments combined, forming obovate 

 structure. Endopodite two-segmented; first segment broad, short; 

 second segment arising from distal lateral surface of first, length 

 slightly greater than width, segment broadly rounded (fig. 18c). 



Fourth thoracic leg uniramous, four-segmented. Protopodite one- 

 segmented, length slightly less than combined lengths of all three 

 exopodite segments. Protopodite with single plmnose setule from 

 outer distal corner. Exopodite three-segmented; first segment short, 

 with single, short, simple spine from distal end, spine encircled by 

 frilled membrane. Second segment with row of toothlike denticula- 

 tions along outer margin, with simple spine from slightly swollen 

 distal end, spine encircled by frilled membrane. Third segment with 

 toothlike denticulations along outer margin as in second, distal end 

 with three spines, outermost short, simple, without denticulations; 

 middle spine longer, margins heavily denticulated (fig. 18/); inner 

 spine long, lightly denticulated. Three terminal spines encircled by 

 frilled membrane (fig. 18e).
