CL = 127 mm) mudd turtle belonging to the K. scorpioides speciescomplex.It is most similar to K. integrum and K. oaxacae, but is distinguishable from other Kinosternon species by the following combination of characteristics in adults (see Tables 1 and 2): ( 1) a depressed. weakly tricarinate carapace: (2) a relatively small plastron (smaller in adult males than in adult females and juveniles) which does not completely close the ventral opening ofthe shell (PHW/CW: 4 4 50.5—57.6%; 7 7 56.7—73. 1 %); (3) anterior plastral lobe freely moveable. posterior lobe slightly moveable: (4) pos tenor plastral lobe with a distinct posterior notch. more deeply notched in males than in females (Fig. 1 ): (5) fixed portion of plastron of moderate length (interabdominal seam length/CL: 46 21—27%: 7 7 23—29%): (6) bridge naiow (BRL/CL: 6 15—21%: 7 7 20—23%): (7) axillary and inguinal scutes in contact: (8) first vertebral scute (Vl ) con- tacts M2 in only I 2% ofadults: (9) opposed patches of horny scales on the posterior thigh and leg ( clasping organs ) absent in males and females: and (10) tail of males and females terminating in a horny spine [incomplete OCR from BERRY et al. 1997].
 
CommentPublication date: Rogner (1996) used the name Kinosternon chimalhuaca apparently before the actual description (BERRY et al. 1997). See ROGNER et al. 2013.

Distribution: Not in Nayarit fide LOC-BARRAGÁN et al. 2024 (checklist Nayarit). 
EtymologyThe specific name chimalhuaca is taken from the tribe of native Americans suggested to have occupied southern Pacific coastal Mexico in the historical novel Aztec by novelist Gary Jennings (1980).
