Figure 26. Pleon-holding mechanism of Ocypodidae. a-b: Leptuca festae (Nobili, 1902), ♂, 14 × 9 mm, El Salvador (SMF2012a). (a) Thoracic sternum without pleon, edge of pleonal clasping apparatus visible. (b) Ventral surface of pleon, notch formed by both pleon segment 6 and telson indicated. c-d: L. festae, ♀, El Salvador (SMF44017). (c) Thoracic sternum of female without eggs (14 × 9 mm), pleon visible at bottom of picture. (d) Female carrying eggs (12 × 8 mm), structures of pleonal clasping apparatus cannot come into contact. e-f: Ocypode gaudichaudii H. Milne Edwards & Lucas, 1843, ♂, 36 × 30 mm, Peru (ZMK1929). (e) Right thoracic sternum without pleon, setal tuft on sternite 5 visible. (f) Ventral surface of pleon. A: anterior; ca: clasping apparatus (sternal portion); E: eggs; fl: flat surface of pleon segment 6; G: gonopods; i: intestine; n: notch; P: posterior; s: setae; sac: sterno-abdominal cavity; st: setal tuft; S5: sternite 5; t: telson. Scale bar = 1 mm.
