Additional Comments:
| Question # | Short Name | Question Text | Response | Comments |
| 1 | Extinction risk | Current IUCN Red List category. [Data obtained from the IUCN Red List.] | Data Deficient (DD) | |
| 2 | Possibly extinct | Is there a strong possibility that this species might be extinct in the wild? | Unknown | We don't know anything about this species. |
| 3 | Phylogenetic significance | The taxon’s Evolutionary Distinctiveness (ED) score, as generated by the ZSL EDGE program. (These data are not editable by Assessors). | ED value 20 - 50 | |
| 4 | Protected habitat | Is a population of at least 50% of the individuals of the taxon included within a well-managed or reliably protected area or areas? | Unknown | This species is known only from the type locality, "Kempholey, Hassan" (Rao 1937), in the Western Ghats of India, at around 200 m asl. There is no further information at this time (Nikhil Modak, pers. comm. September 2020). |
| 5 | Habitat for reintroduction, conservation translocation or supplementation | Does enough well-managed and reliably protected habitat exist, either within or outside of currently protected areas that is suitable for conservation translocation, including population restoration or conservation introduction? | No / unlikely | This species is known only from the type locality, "Kempholey, Hassan" (Rao 1937), in the Western Ghats of India. |
| 6 | Previous reintroductions | Have reintroduction or translocation attempts been made in the past for this species? | No | |
| 7 | In situ conservation activities | Are any in situ conservation actions currently in place for this species? (Only required if a Red List Assessment has not been completed, or if new actions have been implemented since the last Red List Assessment. (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.). | Yes / probably | This species is protected by national legislation. |
| 8 | In situ conservation activities | Are additional in situ conservation actions required to help conserve this species in the wild (e.g. habitat restoration and/or protection, control of invasive species, national legislation etc.)? | Unknown | |
| 9 | In situ research | Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? | Yes | Further research is required on its distribution, population, ecology, use and threats (Nikhil Modak. pers. comm. September 2020). |
| 10 | Threat mitigation | Are the threats facing the taxon, including any new and emerging threats not considered in the IUCN Red List, potentially reversible? | Threats unknown | It is known only from the lost holotype, so its population status is unknown. Between 2015-2017, surveys have been carried out to look for this species over two breeding seasons, but no further records have been found (Nikhil Modak, pers. comm. September 2020). Linear infrastructure development is a major threat, along with he development of structures to prevent landslides, which will affect the rock crevices required by the species (Nikhil Modak and Keerthi Krutha, pers. comm. October 2020). |
| 11 | Over-collection from the wild | Is the taxon suffering from collection within its natural range, either for food, for the pet trade or for any other reason, which threatens the species’ continued persistence in the wild? | No / unlikely | |
| 12 | Population recovery | Is the known population of this species in the wild large enough to recover naturally, without ex situ intervention if threats are mitigated? | Unknown | It is known only from the lost holotype, so its population status is unknown. |
| 13 | Action plans | Does an Action Plan for the species already exist, or is one currently being developed? | No | |
| 14 | Biological distinctiveness | Does the taxon exhibit a distinctive reproductive mode, behaviour, aspect of morphology or physiology, within the Order to which it belongs (e.g. Anura, Passeriformes etc.)? | No aspect of biology known to be exceptional | This species has semi-aquatic tadpoles that develop outside of waterbodies on wet rocks and mosses, and have long tails and hindlimbs which develop earlier compared to other anuran species (Nikhil Modak and K.V. Gururaja pers. comm. September 2020). |
| 15 | Cultural/socio-economic importance | Does the taxon have a special human cultural value (e.g. as a national or regional symbol, in a historic context, featuring in traditional stories) or economic value (e.g. food, traditional medicine, tourism) within its natural range or in a wider global context? | No | |
| 16 | Scientific importance | Is the species vital to current or planned research other than species-specific ecology/biology/conservation within the Order to which it belongs (e.g. Anura, Passeriformes etc.) e.g. human medicine, climate change, environmental pollutants and conservation science? | No research dependent on this species | |
| 17 | Ex situ research | Does conserving this species (or closely related species) in situ depend upon research that can be most easily carried out ex situ? | No | |
| 18 | Ex situ conservation activities | Is any ex situ research or other ex situ conservation action currently in place for this species? (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.) | No / unlikely | |
| 19 | Husbandry analog required | If an ex situ rescue program is recommended for this species, would an analog species be required to develop husbandry protocols first? | Unknown | |
| 20 | Husbandry analog | Do the biological and ecological attributes of this species make it suitable for developing husbandry regimes for more threatened related species? i.e. could this species be used in captivity to help to develop husbandry and breeding protocols which could be used for a similar, but more endangered species at a later stage? | No | |
| 21 | Captive breeding | Has this species been successfully bred and/or maintained in captivity? | Not held in captivity to date | |
| 22 | Conservation education/ecotourism potential | Is the species especially diurnal, active or colourful, or is there an interesting or unusual aspect of its ecology that make it particularly suitable to be an educational ambassador for conservation of the species in the range country, either in zoos or aquariums or within ecotourism activities? | No | |
| 23 | Mandate | Is there an existing conservation mandate recommending the ex situ conservation of this taxon? | No | |
| 24 | Range State approval | If an ex situ initiative was proposed for this species, would it be supported (and approved) by the range State (either within the range State or out-of-country ex situ)? | Yes / probably | |
| 25 | Founder specimens | Are sufficient animals of the taxon available or potentially available (from wild or captive sources) to initiate an ex situ program, if one was recommended? | Unknown | Research into availability of founders needs to be prioritised. |
| 26 | Taxonomic status | Has a complete taxonomic analysis of the species in the wild been carried out, to fully understand the functional unit you wish to conserve (i.e. have species limits been determined)? | No | Research into species validity needs to be prioritised. The holotype of this species is lost, and designation of a neotype is needed if this proves to be a valid species. Rao (1937) originally described this species as Philautus longicrus, but Bossuyt and Dubois (2001) transferred it from Philautus to Indirana. |
