The geographic variation in body size and shape of an organism may reflect the underlying evolutionary processes, including inter- or intra-species interaction, niche differentiation, and the history of the species. Carabus (Apotomopterus) masuzoi (Imura et Sato, 1989) is an endemic ground beetle species distributing in high mountains of the central Taiwan. All members of Carabus beetles are wingless and considered to have low dispersal capacity. We analyzed the geographic pattern of body size and shape variation in two C. masuzoi populations from Mt. Ta-Hsueh Shan and Mt. Tai-Ping Shan. We measured the body size of 25 males and 25 females for each populations and used a total of 62 landmarks of different ventral body segments. Our results showed that the overall ratio of female to male body length was 1.06, and the sexual difference in body size of the two populations were 1.08 (Mt. Ta-Hsueh Shan) and 1.05 (Mt. Tai-Ping Shan).The female body length of each of the two populations (22.72 ± 0.74 mm in Mt. Ta-Hsueh Shan, 23.98 ± 0.97 mm in Mt. Tai-Ping Shan) were significantly greater than that of males (20.68 ± 0.74 mm in Mt. Ta-Hsueh Shan, 22.78 ± 0.94 mm in Mt. Tai-Ping Shan) (p< 0.000). Female and male body lengths of Mt. Tai-Ping Shan were greater than that of Mt. Ta-Hsueh Shan (p < 0.000). The mean shape of head, pronotum and abdomen between the two populations were significantly different as indicated by bootstrap resampling F-test (p=0.004, 0.0044 and 0.0047, respectively). When the body size becomes greater, the body shape of the beetles appears to become more flatter. Our results suggest that the landmark-based geometric morphometrics is useful for quantifying the body size and shape variation of C. masuzoi populations, and the beetle population from Mt. Ta-Hsueh Shan and Tai-Ping Shan differ substantially in external morphology which may reflect the influence of ecological and evolutionary processes.
