Dorsal arm plates are oval or elliptical. The number of arm spines is identical on both sides of the arm. The shape of the arm spines varies among species: slender and elongated in Breviturma longispina, B. paucigranulata, and B. pica; hollow and fragile in B. pusilla; short and thick in B. brevipes, B. dentata, B. doederleini, and B. krohi . Two tentacle scales are present.</p></div>	https://treatment.plazi.org/id/0385423B9820FFCFFE6273D2FBD4FBCE	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

The oral shields are subequal in length and width (Figs 2D, 3C), while the adoral shields are spear-shaped (Figs 2D, 3D). There are four oral papillae and 10–12 tooth papillae (Fig. 2D). The dorsal arm plates are transversely elliptical (Figs 2E, 3G). The number of arm spines ranges from three to four, with the second dorsalmost arm spines on the 15 th –18 th arm segments being the longest and exhibiting slightly swollen tips (Fig. 2E–F). The ventral arm plates are pentagonal (Figs 2F, 3H), each bearing two oval tentacle scales on its lateral sides (Fig. 2D, F). The coloration of the dorsal disc is variegated, ranging from yellowish-gray to greenish-gray (Figs 2A, 4), with a dark, axe-shaped central pattern on the dorsal arm plates (Figs 2E, 4). The arms are transversely banded (Figs 2A, 4), with the arm spines showing a light gray base color and irregular, darker annulation (Fig. 2E–F). The ventral side is uniformly light in color (Fig. 2B).</p><p>Etymology</p><p>The species name securis is derived from the Latin word meaning ‘axe’, referencing the axe-shaped dark patterns on the dorsal arm plates. The name is used as a noun in apposition.</p><p>Type material</p><p>Holotype TAIWAN – Taitung County • (DD = 14.99 mm); Lanyu, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=121.55825&amp;materialsCitation.latitude=22.022055" title="Search Plazi for locations around (long 121.55825/lat 22.022055)">Hongtou</a>; 22°01′19.4″ N, 121°33′29.7″ E; depth &lt;1 m; 28 Sep. 2022; K.

Second dorsalmost arm spines from 15 th –18 th arm segment of most large individuals prominently elongated, swollen, absent in smaller individuals (Fig. 5D). For the detailed results, see Morphological analyses on Breviturma securis sp. nov.</p><p>Coloration</p><p>In life, the dorsal disc and ventral interradial areas exhibit a yellowish-gray to greenish-gray coloration, variegated with lighter and darker patches. These regions are adorned with discontinuous short dark lines that never form a reticular pattern (Figs 2A, 4A–D). In juveniles, a dark ‘star’ may occasionally appear at the center of the disc but never connects to the arm base (Fig. 4E–F). Dorsal arm plates share the disc’s background color but feature a dark ‘axe-shaped’ pattern in the center, the ‘axe bit’ is at proximal side and the ‘axe poll’ is at the distal side (Fig. 2E). Darker plates occur every two to three segments on both the dorsal and ventral arm plates, giving the arms a transversely banded appearance (Figs 2A, 4A–F). Arm spines are light gray with irregular darker annulations (Fig. 2E–F). Oral shields, jaws, and ventral arm plates are very light in color, either white or creamy yellow (Fig. 2B, D, F). Tentacle scales are white, occasionally exhibiting tiny dark dots (Fig. 2D, F). Tube feet are white (Fig. 2D, F).</p><p>Ecological and behavioral notes</p><p>This species inhabits sandy substrates beneath rocks, ranging from the intertidal zone to shallow subtidal depths of up to 8 m. It is highly sympatric with other brittle stars, including B. dentata, B. krohi, Ophiocoma scolopendrina, and Amphipholis squamata (Delle Chiaje, 1828) . On one occasion, an individual was parasitized by a snail ( Eulimidae sp.) attached at the base of an arm (Fig. 4G–H).</p><p>Distribution</p><p>Reunion Island; Taiwan; Papua New Guinea.</p><p>Remarks</p><p>Breviturma securis sp. nov. was previously misidentified as B. brevipes in Taiwan, including in academic literature (e.g., Chao et al. 1991) and in field guides (Hung 2000). The photographs for B. brevipes in those publications obviously match the new species in both morphology and coloration, showing strong arm spines, a greenish base color, variegated dark and light spots, and a conspicuous dark ‘axe’ pattern on the dorsal arm plates. For the same reasons, in a field guide to tropical Indo-Pacific echinoderms (Ryanskiy 2020), three records were identified as Breviturma sp., Ophionereis sp., and Ophiodermatidae sp., respectively; all should be referred to this new species. In our previous work (Shih et al. 2023), the new species was recorded from Lanyu, Taiwan, under the name Breviturma aff. dentata because of the presence of four strong arm spines, yet it exhibited a completely different coloration from the typical B. dentata (Müller &amp; Troschel, 1842) . The specimens from Lanyu are now designated as the holotype and paratypes in this study.</p><p>Furthermore, three specimens labeled as “ Ophiocoma brevipes ” archived in the NMNS (see Other material examined under Breviturma securis sp. nov.) were reexamined and confirmed to belong to this new species. These two species can be distinguished by their coloration and the number of AS on the proximal arm segments (see Discussion).</p></div>	https://treatment.plazi.org/id/0385423B9820FFCDFDF87514FC8FFDA5	Public Domain	No known copyright restrictions apply.

The oral shields are trapezoidal, while the adoral shields are unevenly triangular. There are four oral papillae and eight to ten tooth papillae. The dorsal arm plates are oval in shape. The arm spines are tapering, with numbers ranging fromthree to five; the proximal arm segments consistently have five spines. The ventral arm plates are pentagonal, each bearing two oval tentacle scales on its lateral sides. The coloration is yellowish-brown, with dark brown patterns on the dorsal disc (Fig. 6A, C, E–F). Some of these patterns are pentamerously symmetrical, while others are uniformly dark. The central patterns on the dorsal arm plates are also dark. The arms are transversely banded (Fig. 6), with the arm spines being dark gray. On the oral side, the coloration is light, with tiny dark spots scattered across the surface (Fig. 6B, D).</p><p>Material examined</p><p>TAIWAN – Penghu County • 10 specs (DD = 4.03–12.17 mm); Wang’an, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=119.666504&amp;materialsCitation.latitude=23.256916" title="Search Plazi for locations around (long 119.666504/lat 23.256916)">Dongjiyu</a>; 23°15′24.9″ N, 119°39′59.4″ E; depth &lt;1 m; 22 Apr. 2024; K.
