Taxonomic notes. – Recently, an examination of the lectotype and a paralectotype of Rana okinavana revealed that the species is identical with R. psaltes. Therefore, the name R. psaltes is relegated to a subjective junior synonym of R. okinavana (see Matsui, 2007). This author stated that R. psaltes from Taiwan (Chou, 1994) should be mentioned as R. okinavana too. Diagnostic characters. – Rana okinavana is characterized by the following combination of characters: (1) body stocky; (2) SVL of adult males 41.6 ± 1.4 (40 – 42.8 mm), adult females 46.7 ± 2.9 (44.6 – 48.8 mm); (3) nostril directed laterally; (4) marginal grooves on fingers present or absent; (5) marginal grooves on toes present; (6) mid-dorsal stripe present; (7) external vocal sac absent; (8) nuptial pad poorly developed, absent on prepollex but present as small pad on median surface of first finger; (9) suprabrachial gland present and elongate; (10) nest construction behavior present; (11) spinules on back absent in adult males and females; (12) spinules on ventrum absent in adult males and females; (13) tibio-tarsal articulation reaching eye center to near nostril; (14) finger tips dilated; (15) toe tips dilated; (16) relative length of fingers II <I <IV <III; (17) relative length of toes I <II <V <III <IV; (18) pigmented eggs; (19) larval keratodont formula 1: 1 + 1 / 1 + 1: 2; (20) Calling: 17 – 25 loud, fast-repeated, “ gulo ” pulses.	en	Chuaynkern, Yodchaiy, Ohler, Annemarie, Inthara, Chantip, Duengkae, Prateep (2010): A Revision Of Species In The Subgenus Nidirana Dubois, 1992, With Special Attention To The Identity Of Specimens Allocated To Rana Adenopleura Boulenger, 1909, And Rana Chapaensis (Bourret, 1937) (Amphibia: Anura: Ranidae) From Thailand And Laos.

Taxonomic notes. – Rana adenopleura was described by Boulenger (1909) from four specimens collected at “ Fuhacho ”, Taiwan. Several authors regarded the frogs from continental China belonging to R. adenopleura and regarded the congeneric species from Fukien namely R. caldwelli as a synonym (Pope, 1931; Liu, 1950; Kuramoto, 1985; Chou, 1999; Orlov et al., 2002). Based on published evidences, Dubois (1992) proposed to keep the name of R. adenopleura for Taiwan population and restricted the name of R. caldwelli for the Fujian population. As given above, the morphological and morphometrical comparisons confirm the differences between these two species as similar as the proposal of Dubois (1992). Diagnostic characters. – Rana adenopleura is characterized by the following combination of characters: (1) body elongated; (2) SVL of adult males 48.5 ± 2.7 (44.6 – 53.9 mm), adult females 49.9 ± 1.9 (47.6 – 52.8 mm); (3) nostril directed laterally; (4) marginal grooves on fingers present or absent; (5) marginal grooves on toes present; (6) mid-dorsal stripe present or absent; (7) external vocal sac present; (8) nuptial pad present on thumb and first finger, forming a single pad; (9) suprabrachial gland present and large; (10) nest construction behavior absent; (11) spinules present on entire dorsum of head and body (in adult males); (12) spinules on ventrum present in adult males; (13) tibio-tarsal articulation reach snout tip or between eye to snout; (14) finger tips dilated; (15) toe tips dilated; (16) relative length of fingers II <I <IV <III; (17) relative length of toes I <II <III = V <IV; (18) pigmented eggs; (19) larval keratodont formula 1: 1 + 1 / 1 + 1: 2; (20) Calling: 2 – 4 loud “ gai-gai- … ” notes.	en	Chuaynkern, Yodchaiy, Ohler, Annemarie, Inthara, Chantip, Duengkae, Prateep (2010): A Revision Of Species In The Subgenus Nidirana Dubois, 1992, With Special Attention To The Identity Of Specimens Allocated To Rana Adenopleura Boulenger, 1909, And Rana Chapaensis (Bourret, 1937) (Amphibia: Anura: Ranidae) From Thailand And Laos.

Sikang Province, Ta-liang-shan (FMNH 49464 - 466), Chaochiao (FMNH 49460, 49462). Taxonomic notes. — Rana caldwelli was described by Schmidt (1925) based on two specimens from Fujian. He distinguished his new frog from R. adenopleura by their more projecting snouts, rougher skin and posteriorly broken up dorsolateral glandular folds. Pope (1931) compared Schmidt’s types with his new series of 98 specimens and showed that the characters separating R. caldwelli and R. adenopleura were not diagnostic and placed R. caldwelli in the synonymy of the original species R. adenopleura. This consideration was followed in subsequent works (Liu, 1950; Chou, 1999). As results given above, the species Rana caldwelli is recognized as valid species as similar to Dubois (1992). Diagnostic characters. – Rana caldwelli is characterized by the following combination of characters: (1) body elongated; (2) SVL of adult males 49 ± 3.2 (43.1 – 56.1 mm), adult females 51.6 ± 2.3 (47.7 – 55.4 mm); (3) nostril directed laterally; (4) marginal grooves on fingers present or absent; (5) marginal grooves on toes present; (6) mid-dorsal stripe present or absent; (7) external vocal sac present; (8) nuptial pad present on thumb and first finger, forming a single pad; (9) suprabrachial gland present and large; (10) nest construction behavior absent; (11) spinules on back present only on posterior half of back (in adult males); (12) spinules on ventrum present in adult males; (13) tibio-tarsal articulation reach snout tip; (14) finger tips dilated; (15) toe tips dilated; (16) relative length of fingers II <I <IV <III; (17) relative length of toes I <II <III = V <IV; (18) pigmented eggs; (19) larval keratodont formula 1: 0 + 0 / 1 + 1: 1; (20) Calling unknown.	en	Chuaynkern, Yodchaiy, Ohler, Annemarie, Inthara, Chantip, Duengkae, Prateep (2010): A Revision Of Species In The Subgenus Nidirana Dubois, 1992, With Special Attention To The Identity Of Specimens Allocated To Rana Adenopleura Boulenger, 1909, And Rana Chapaensis (Bourret, 1937) (Amphibia: Anura: Ranidae) From Thailand And Laos.

Laos: Xieng Khouang Province, Pek District, Phonsavan Market (FMNH 256531 – 532). Thailand: Loei Province, Phu Rue District, Phu Luang Wildlife Sanctuary (FMNH 262578 – 579, THNHM 08711 – 716). Phetchabun Province, Nakhon Thai District, Phu Hin Rong Kla National Park (THNHM 13113 – 118). Taxonomic notes. — Rana lini was described by Chou (1999) based on specimens collected from Simao and Honghe Perfectures, Yunnan Province (China). Seven specimens from Simao Perfecture were designated as holotype (NMNS 3258) and paratypes (NMNS 3190 - 1 to NMNS 3190 - 7). Remaining five specimens from Honghe Perfecture (NMNS 3168 - 1 to NMNS 3168 - 5) were designated to the “ referred specimens ”. In this study, we examined four specimens from Honghe Perfecture as in specimens studied. In the original description of Rana lini by Chou (1999), some morphological characters are confusing and do not agree with our examination. Chou’s (1999: 391) Table 1 provided several comparisons of morphological, acoustical, and behavioral characters of frogs of the subgenus Nidirana. Of those, there are two characters (vocal sacs and dermal fold width of 2 nd and 3 rd fingers) which differ from our observations. The vocal sacs were defined by Chou (1999) in two states: distinct and indistinct. We also defined this character in two states but in different terms (present and absent). If present, the skin of throat at the corner of lower jaw has wrinkled skin or pouches but if absent, the skin does not have such structures. Chou (1999) observed vocal sacs in R. chapaensis, R. daunchina and R. okinavana (as R. psaltes) as indistinct but we observed this character as present (as wrinkled skin) except in R. okinavana. Chou (1999) observed presence of inner and outer dermal fold on second and third fingers of all Nidirana species. We observed such a skin fold only on the inner sides of second and third fingers. The dermal fold along lateral edge of 5 th toe was observed by Chou (1999) as indistinct in R. chapaensis, R. daunchina and R. okinavana (as R. psaltes). We observed this character as present in those three species. Chou’s (1999: 391) Table 1 listed the dermal fold along lateral margin of 5 th toe in R. chapaensis as indistinct but in his key to species (Chou, 1999: 398), this species was placed in the group of species which have evident or distinct dermal fold along lateral margin of 5 th toe. As mentioned above, the confusion of some observed characters between the first description (Chou, 1999) and this study lead us to make the description based on the specimen from Thailand as below. Diagnostic characters. – Rana lini is characterized by the following combination of characters: (1) body elongated; (2) SVL of adult males 53.7 ± 4.1 (44.1 – 57.9 mm), adult females 59 ± 1.6 (57.7 – 60.7 mm); (3) nostril directed laterally; (4) marginal grooves on fingers present or absent; (5) marginal grooves on toes present; (6) mid-dorsal stripe present; (7) external vocal sac present; (8) nuptial pad present on thumb and first finger, formed as one pad; (9) suprabrachial gland present and large; (10) nest construction behavior absent; (11) spinules on back present on posterior half of back in adult males; (12) spinules on ventrum present in adult males; (13) tibio-tarsal articulation beyond snout; (14) finger tips dilated; (15) toe tips dilated; (16) relative length of fingers II <I <IV <III; (17) relative length of toes I <II <V <III <IV; (18) pigmented eggs; (19) larval keratodont formula 1: 1 + 1 / 1 + 1: 2; (20) Calling: 5 - 7 loud “ goo-goo- … ” notes.	en	Chuaynkern, Yodchaiy, Ohler, Annemarie, Inthara, Chantip, Duengkae, Prateep (2010): A Revision Of Species In The Subgenus Nidirana Dubois, 1992, With Special Attention To The Identity Of Specimens Allocated To Rana Adenopleura Boulenger, 1909, And Rana Chapaensis (Bourret, 1937) (Amphibia: Anura: Ranidae) From Thailand And Laos.

Natural history notes. – The specimens from Phu Hin Rong Kla National Park (Nakhon Thai District, Phetchabun Province) were caught in a permanent pond (location 47 Q 0714929 UTM 1878834, 1,300 m asl) which has drainage conduit to move out water from the pond (Fig. 5). The frogs were sitting on water plants and calling. Several frogs from Man Daeng Protected Unit (location 47 Q 0718477 UTM 1872542, 1,647 m asl) were sitting on the bank of an artificial pond and were also calling. The calls of the frogs were heard in the daytime also. Specimens from Phu Luang Wildlife Sanctuary (Phu Rue District, Loei Province) were caught in Pine forest at approximately 1,500 m asl. These frogs are not utilized for food.	en	Chuaynkern, Yodchaiy, Ohler, Annemarie, Inthara, Chantip, Duengkae, Prateep (2010): A Revision Of Species In The Subgenus Nidirana Dubois, 1992, With Special Attention To The Identity Of Specimens Allocated To Rana Adenopleura Boulenger, 1909, And Rana Chapaensis (Bourret, 1937) (Amphibia: Anura: Ranidae) From Thailand And Laos.
