Taxonomic Description:

  • body shape: subcylindrical, moderately depressed
  • coloration: ground color olivaceous or greenish-gray; dorsal surface of chela is aquamarine
  • spines: hepatic spines; cervical spine;strong branchiostegal spine; cephalic spine or tubercle
  • rostrum: long, narrow, lanceolate rostrum; narrow margins that strongly converge from base to cephalodorsally directed apical spine
  • areola: 4-7 punctations across narrowest part
  • chelae: mesial margin of palm with double row of tubercles; fingers moderately to strongly gaping; strong longitudinal ridges
  • other characteristics: suborbitalangle obtuse to subacute
  • form I male gonopod: shaft straight; central projection not tapered, curvedover 90° to plane of shaft, with moderate subapical notch; mesial processbulbous, tapered, constricted near tip, and directed caudolaterally; disklike caudal knob at base of central projection
