Additional Comments::

Question # Short Name Question Text Response Comments
1 Extinction risk Current IUCN Red List category. [Data obtained from the IUCN Red List.] Least Concern (LC)
2 Possibly extinct Is there a strong possibility that this species might be extinct in the wild? No / unlikely
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
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? No / unlikely This species occurs on the Pacific slope of the Sierra Madre del Sur de Guerrero at the Río Atoyac drainage, in the northern areas of Puerto del Gallo. It has also been recorded from the Sierra de Tecpan
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
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.). No / unlikely
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.)? Yes / probably Habitat restoration and avoid shifting from red to yellow banana plantation.
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 work would improve estimates of population size, distribution and trends.
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 are likely to be reversible in time frame to prevent further decline / extinction Even though the species persists in highly modified habitat (e.g. red bananas in regions of shade grown coffee), the conversion of land to yellow banana plantations (which are more open and less humid) is the only known threat to the species, however this is not occurring at high rates within its range (C. Grunwald and S. Rovito pers. comm. 2019).
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 Until recently, it had not been collected since it was first described in the 1980s, although the lack of records was probably due to security concerns, but it was fairly common when first found. Just a couple of individuals were recorded in 2015 or 2016 near the type locality and the same numbers in 2017 at a new locality (J. Jones and Ivan Ahumada pers. obs. 2017).
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
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? Yes Further work would improve estimates of population size, distribution and trends.
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? No / unlikely
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)? Yes
