TL;DR: Seven new species of Eimeria are described from Japanese lizards, four apparently intestinal residents, the oocysts being recovered from gut contents, and three inhabitants of the epithelium of the gall bladder and bile ducts of their respective hosts.
Abstract: BOVEE, E. C. 1971. New species of Eimeria from lizards of Japan. Trans. Amer. Micros. Soc., 90: 336-343. Seven new species of Eimeria are described from Japanese lizards. Four are apparently intestinal residents, the oocysts being recovered from gut contents: Eimeria michikoa n. sp., from Gekko japonicus; E. telfordi n. sp., from Gehyra mutilata; E. rountreei n. sp., from Takydromus tachydromoides; E. sami, from Eumeces oshimensis. Three other species are inhabitants of the epithelium of the gall bladder and bile ducts of their respective hosts: E japonicis n. sp., from Gekko japonicus; E. pellopleuris n. sp., from Lygosoma pellopleurum; E. japaluris n. sp., from Japalura polygonata. There is no oocystic residuum, no polar body, no micropyle, nor Stieda body on sporocyst for any of these species.

TL;DR: Re-examination of the holotype of Japalura swinHonis from the northern part of Taiwan revealed that this specimen differs from the population currently treated as swinhonis but is identical with J. mitsukurit, thus, mITSukurii is a junior synonym of swin Honis.
Abstract: Re-examination of the holotype of Japalura swinhonis from the northern part of Taiwan revealed that this specimen differs from the population currently treated as swinhonis but is identical with J. mitsukurit. Thus, mitsukurii is a junior synonym of swinhonis. The population of Japalura from northern Taiwan, long regarded as swinhonis, in reality is an unnamed subspecies of J. polygonata, here described as japalura polygonata xanthostoma.

TL;DR: There was a trade-off between fighting ability and maneuverability because of morphological differences that allowed the coexistence of the two species, and it is suggested that there were potential competitors if resources are limited.
Abstract: We investigated the underlying mechanism of coexistence of two sympatric Japalura lizards (Japalura swinhonis and Japalura polygonata xanthostoma). We examined the differences in resource use along three resource dimensions: time, space, and diet. Specifically we tested two ecomorphological hypotheses. Correspondence exists between: perch habitat and limb morphology, and diet and head morphology. The species with shorter forelimbs would perch on narrower surface. The species with larger heads would consume larger or tougher prey. The results showed that the two species did not divide resources by temporal partitioning. Spatially, the two species used similar macrohabitats. However, female J. swinhonis, perching lower and on narrower surfaces, differed from other groups in perch habitats. However, male J. swinhonis and J. p. xanthostoma, despite size and shape differences, were similar in perch habitat. In addition, high diet overlap was detected both intra- and interspecifically despite the presence of significant differences in head sizes. In conclusion, male J. swinhonis and J. p. xanthostoma used largely overlapping resources and therefore, might be potential competitors if resources are limited. We suggest that there was a trade-off between fighting ability and maneuverability because of morphological differences that allowed the coexistence of the two species. Although male J. swinhonis, being larger, may have better fighting ability, J. p. xanthostoma could maneuver around tree trunks and branches to search for prey and avoid fighting more easily.

TL;DR: Males of the present subspecies differ from those of other subspecies in having a series of large white spots against a dark grayish tan on the dorsolateral surface of the body, whereas the females are characterized by brilliant green dorsal coloration.
