In July 2024, the description of a new species of tropical kiwi from the Philippines was published in Phytotaxa.

Like ๐˜š. ๐˜ข๐˜ท๐˜ฆ๐˜ญ๐˜ญ๐˜ข๐˜ฏ๐˜ข and ๐˜š. ๐˜ฆ๐˜ญ๐˜ฆ๐˜จ๐˜ข๐˜ฏ๐˜ด, the branchlets and leaves of ๐˜š. ๐˜ฅ๐˜ฆ๐˜ค๐˜ฐ๐˜ญ๐˜ฐ๐˜ณ๐˜ข๐˜ต๐˜ข are covered with felt-like tomentum (filamentous hairs) and dense flower clusters. However, ๐˜š. ๐˜ฅ๐˜ฆ๐˜ค๐˜ฐ๐˜ญ๐˜ฐ๐˜ณ๐˜ข๐˜ต๐˜ข differs by having rusty-colored tomentum, cordate (heart-shaped) leaf bases, crenate (rounded-toothed instead of spiky) leaf margins, and fascicled-cymose flowers (crowded together, with a flower at the apex of the flower axis), which grow both in the leaves’ axils (the upper angle between a leaf and a stem) and on branches (ramiflorous).

Significance

๐˜š. ๐˜ฅ๐˜ฆ๐˜ค๐˜ฐ๐˜ญ๐˜ฐ๐˜ณ๐˜ข๐˜ต๐˜ข is the 58th known ๐˜š๐˜ข๐˜ถ๐˜ณ๐˜ข๐˜ถ๐˜ช๐˜ข species in the Philippines. It has only been found in the Mt. Pantaron Range and Mt. Balatukan Natural Park, both in Mindanao. While discovering new species is perhaps the publicโ€™s top-of-mind idea when it comes to what a taxonomist does, the description of organisms previously unknown to science can also serve as a reminder โ€” or warning โ€” about the dire conditions of their habitats.

According to the authors, the Mt. Pantaron Range is currently not protected by any law, despite harboring many unique species and being under constant threat of massive forest cover loss due to development, mining, and unsustainable resource harvesting. Moreover, without appropriate protection laws, the indigenous Manobo, Higaonon, and Bukidnon peoples could someday lose this mountain range, a home they consider sacred.

Mt. Balatukan, on the other hand, is a protected area; however, there is evidence that poachers and illegal loggers still operate there shamelessly. The researchers also note that armed conflict in the area has โ€œmade parts of it inaccessible, hampering implementation of conservation programs.โ€

Lastly, due to โ€œthe lack of revisionary studies and a clear understanding of species boundaries and morphological variation,โ€ there is a knowledge gap concerning the ๐˜š๐˜ข๐˜ถ๐˜ณ๐˜ข๐˜ถ๐˜ช๐˜ข genus in the Philippines.

Thus, the authors hope that as new species like ๐˜š. ๐˜ฅ๐˜ฆ๐˜ค๐˜ฐ๐˜ญ๐˜ฐ๐˜ณ๐˜ข๐˜ต๐˜ข are found, more people will become involved and invested not only in enhancing our grasp of this fascinating genus, but also in the conservation of culturally significant and geographically isolated biodiversity hubs.โ€”MF
