In fact, the island population of Rhinolophus pumilus on Miyako Island (treated as R. p. miyakonis by Yoshiyuki [1989] or R. cornutus by Simmons [2005]), where almost all forest lands have been converted to agricultural fields, is considered to be extinct because there has been no record of this species since 1971 (Abe et al. 2005).

Wu, Y., Motokawa, M., Harada, M., Thong, V. D., Lin, L. K. and Li, Y. C. (2012). Morphometric variation in the pusillus group of the genus Rhinolophus (Mammalia: Chiroptera: Rhinolophidae) in East Asia. Zoolog. Sci. 29(6): 396-402. AbstractBased on 203 specimens belonging to the Rhinolophus " pusillus group" (Mammalia: Chiroptera: Rhinolophidae), univariate and multivariate morphometric analyses using 19 characters were performed to assess the confused species taxonomy. The results indicated that R. pusillus (including calidus, parcus, and szechuanus) in the continental region and Hainan Island of China and " R. cornutus" in Japan are morphologically divergent species. Rhinolophus cornutus should be further split into R. cornutus (including orii, pumilus, and miyakonis) in the main islands of Japan, the Amami and Okinawa Group of the central Ryukyu Archipelago, and Miyako Group of the southern Ryukyus; and R. perditus and R. imaizumii from the Yaeyama Group in the southern Ryukyus. Rhinolophus monoceros from Taiwan is morphologically more similar to species in Japan than to R. pusillus. In addition to R. pusillus, another form that is morphologically similar to species in Japan was recognized from Langzhong in Sichuan Province; this may represent an undescribed species, and further examination is necessary to determine its taxonomic status. Specimens from Guang'an in Sichuan Province, China, are also different from the others, and are characterized by the smallest skull size. Although further studies are required, these specimens were tentatively identified as R subbadius.. |

"Subspecies pumilus is endemic to Japan, where it is found on three islands in the Ryukyus: Okinawa, Iheya, and Kume. The species is believed to have become extinct on Miyako (30 years ago) and Irabu (probably around 5 years ago)." Source: www.iucnredlist.org/details/19561/0 |

Does anybody know the author of this subspecies? I cannot find it anywhere.

Its holotype was lost due to an airstrike during WWII. No specimen now.
Needed to find its corpse from guano to create a new holotype.

"A possible extinct species of Rhinolophus was reported from Miyako Island. This species was originally described as R. cornutus miyakonis (Kuroda 1924), and later classified into a subspecies of R. pumilus (Yoshiyuki 1989) or an independent species on Miyako Island (Maeda 2001). Hirasawa et al. (2006) preliminarily discussed, based on paleontological analysis, that lower teeth of the Rhinolophus species on Miyako Island could not be distinguished from those of the other species. However, the dental morphology of the fossil specimens from Sabichi-do Cave fit exactly to that of living R. perditus, comparing with the recent remains collected from Ishigaki Island."
