inner distal surface. Both inner spines flattened, lateral margins 

 ramified into small secondary spines (fig. 16a). 



Second thoracic leg biramous. Protopodite two-segmented; first 

 segment small, less than half length and width of second segment. 

 Second segment with large, club-shaped articular process protruding 

 from outer proximal corner. Exopodite three-segmented; first seg- 

 ment longer than combined lengths of second and third segments, 

 with strong spine from outer distal corner directed across surfaces of 

 second and third segments. Second segment short, with smaller 

 spine from outer distal corner; third segment slightly longer than 

 second, broadly rounded, with two small spines on outer lateral 

 margin. Endopodite three-segmented; first and second segments 

 about equal in length, third short, broadly rounded (fig. IQb).

Figure 16. — Anuretes menehune, new species (holotype female, allotype male): a, first 

 thoracic leg; b, second thoracic leg; c, third thoracic leg of female; d, protopodite process of 

 third thoracic leg of male; e, fourth thoracic leg. 



Third thoracic leg biramous. Protopodite one-segmented, flattened, 

 inner surface extending posteriorly, under genital segment, as large, 

 heavily chitinized, slightly curved, blunt-tipped process in female; 

 male protopodite process extending slightly from segment, not as 

 heavily chitinized as female process (figs. lQc,d). Exopodite one- 

 segmented, with curved, one-parted process arising from junction 

 of exopodite and protopodite. Single segment of exopodite longer 

 than wide, broadly rounded. Endopodite two-segmented; first 

 segment broad, with broad distal lobe; second segment broadly 

 rounded, attached to inner corner of first segment (fig. 16c). 



Fourth thoracic leg uniramous, three-segmented. Protopodite 

 one-segmented, longer than combined lengths of two exopodite
