Pralesnička Lamasova (Ranitomeya lamasi), též pralesnička jihoperuánská[2] je druh pralesničky z rodu Ranitomeya. Žije v amazonských deštných pralesích na severu Bolívie (departement Pando), západě Brazílie (stát Acre) a východním Peru (departementy Madre de Dios a Ucayali).
Jako většina pralesniček rodu Ranitomeya, pralesnička Lamasova je středně jedovatý druh pralesničky. Její kůže produkuje sekrety s pumiliotoxiny, které mohou způsobit bolest a mírné svalové křeči, pokud není pralesnička držena opatrně. Příznaky mohou být těžší, když je pralesnička snězena, ale oproti druhům patřícím do rodů Phyllobates a Oophaga pralesnička Lamasova má poměrně mírné pumiliotoxiny typu C, a to ve velmi malém množství na svou velikost.
Pralesnička Lamasova jako všechny pralesničky v zajetí ztrácí jed. Důvod ztráty jedu je obvykle kvůli odstraněni jedovatého hmyzu z potravy. Vědci zjistili, že pralesničky rodu Phyllobates získávají svůj jed z jedovatých brouků z čeledi bradavičníkovitých. Jelikož je pralesnička Lamasova daleko méně jedovatá než pralesničky rodu Phyllobates, zdroj jejich jedu není z bradavičníkovitých brouků, ale z jiného, zatím neznámého hmyzu.

Ranitomeya sirensis is a species of poison dart frog found in the Amazonian rainforests of northern Bolivia (Pando Department), westernmost Brazil (Acre), and eastern Peru.[2]
R. sirensis is known as the Sira poison frog.[2] R. sirensis is kept as a pet by herpetoculturists[1] and is considered to be one of the more difficult poison dart frogs to keep due to its relative rarity and the delicate nature of its tadpoles.
Like most Ranitomeya species, R. sirensis is a mildly toxic poison dart frog.[3] Its skin secretes small amounts of pumiliotoxins which coat the frog and cause pain and mild muscle spasms if the frog is handled carelessly. The symptoms may be more severe if the frog is ingested, but unlike the Phyllobates and Oophaga species, R. sirensis secretes the comparatively mild pumiliotoxin C in very small quantities due to its tiny size. As a result, sirensis mostly rely on their agility, speed, and ability to take shelter in the leaf litter or in dense foliage for protection.
R. sirensis, as with all dendrobatid frogs, loses its poison in captivity. The reason for the loss of its toxicity is thought to be the removal of a toxic insect or other invertebrate from the diet. Scientists have determined that members of the genus Phyllobates derive their dangerously potent toxins from local melyrid beetles.[4] As R. sirensis is much less toxic than the Phyllobates species, the source of its toxin is not thought to be melyrid beetles; instead, it is likely an invertebrate that remains undiscovered.
R. sirensis inhabits premontane, montane and lowland moist secondary tropical forests. It tolerates some degree of habitat modification. It is collected for illegal pet trade, which is a threat particularly to isolated subpopulations with extreme colour morphs.[1]
