Merus without spines, dorsal and ventral margins glabrous. Surface of carpus glabrous, margins of carpus with dense short setae, inner distal angle with 1–3 tiny teeth. Palm bulky; inner surface almost smooth, glabrous; outer surface almost smooth; in male (Fig. 2D), distinct patch of setae at base of fingers, mostly expanding onto fixed finger, in both chelae; in female (Fig. 2E), only line of short setae present at base of occlusal margin of immovable finger.</p><p>Ambulatory legs (Fig. 1) slender, anterior margins of merus, carpus, and propodus covered with short setae, posterior margins with sparse short setae.</p><p>Male pleon (Fig. 2F) narrow, surface smooth, without any granules, lateral margins lined with short setae; telson tongue-shaped, short than sixth somite, distal margin of telson not concave.</p><p>G1 (Fig. 2 H–M) slender, slightly curved towards lateral, tapering, distal part curved laterally and ventrally; tip chitinous, chitinous endpiece shorter, wider and thicker, genital pore widely open distally towards laterally and dorsally.</p><p>Female vulvae (Fig. 2N) with elongated semicircular sternal cover; sunken on inner part.</p><p>Etymology. The species is named after the late Dr. Ngan Kee Ng for her contribution to the taxonomy of brachyurans, especially the family Varunidae (Lee &amp; Jaafar 2022) .</p><p>Ecological notes. This species is common in mangrove and intertidal areas with sandy sediments (J. C. E. Mendoza, personal communication).</p><p>Distribution. Only known from Vanuatu.</p><p>Size. Largest male 24.3 × 19.1 mm (ZRC 2023.0238); largest female 24.5 × 18.8 mm (ZRC 2023.0242).</p><p>Remarks. Among the males of species in Parahelice and Pseudohelice, Par. georgei and all three species of Pseudohelice ( Pse. annamalai, Pse. latreillii, and Pse. subquadrata) can be easily distinguished from remaining four Parahelice species by the absence of a patch of setae in Par. georgei and Pseudohelice species [vs. with patch of setae in other Parahelice species] (K. Sakai et al. 2006; Hsu et al. 2022; Prema et al. 2022; this study). In this regard, Par. ngankeeae sp. nov. resembles Par. balssi, Par. daviei, Par. pilimana and Par. pilosa, but can be separated by the characters of the suborbital cristae and G1s.</p><p>Parahelice ngankeeae can be discerned from Par. balssi by the male suborbital cristae and G1s. In male Par. ngankeeae, the lateral part of the suborbital crista consists of 1 significantly largest elliptical tubercle and 2–3 elongated or rounded tubercles, which are significantly smaller than the largest elliptical tubercle (Fig. 2B) [vs. elongated crest ending with inflated part, followed by 2–4 elongated tubercles, which are larger or equal in size to the inflated part in Par. balssi (K. Sakai et al. 2006: fig. 60; Bouchard et al. 2013: fig. 24D)]; and its male G1 is slender and obviously tapering (Fig. 2H–M) [vs. stout and only slightly tapering in Par. balssi (K. Sakai et al. 2006: fig. 70a, b)].</p><p>Parahelice ngankeeae can be differentiated from Par. daviei and Par. pilimana by the lateral part of the male suborbital cristae and G1s. The lateral part of the suborbital crista comprises 1 significantly largest elliptical tubercle (without Y-shaped or particularly vertically inflated crest) and 2–3 smaller tubercles in Par. ngankeeae (Fig. 2B) [vs. elongated Y-shaped crest and 1–2 smaller tubercles in Par. daviei (K. Sakai et al. 2006: fig. 66a, b; Shih et al. 2020: fig. 2C); and elongated, laterally, particularly vertically inflated crest and 2 smaller tubercles in Par. pilimana (K. Sakai et al. 2006: fig. 65; Shih et al. 2020: fig. 4C)]; and the part near the tip of G1 is relatively stout and only slightly tapering in Par. ngankeeae (Fig. 2H–M) [vs. relatively slender and significantly tapering in Par. daviei and Par. pilimana (K. Sakai et al. 2006: figs. 68a–c, 71a–c; Shih et al. 2020: figs. 2E–H, 4C–H)].</p><p>Parahelice ngankeeae and Par. pilosa can be separated by the male suborbital cristae. The lateral part of the suborbital cristae in Par. ngankeeae is composed of 1 largest elliptical tubercle and 2–3 tubercles, which are significantly smaller and less convex than the largest elliptical tubercle [vs. crest ending with a slightly inflated part, followed by 2 tubercles, which are only slightly smaller and less convex than (or equal to) the inflated part in Par. pilosa (K. Sakai et al. 2006: fig. 61; Shih et al. 2020: fig. 6C)].</p><p>The female Par. ngankeeae is morphologically remarkably similar to Par. balssi, Par. daviei, Par. pilimana, and Par. pilosa, but can be distinguished by the suborbital cristae. In female Par. ngankeeae, the lateral part of the suborbital crista comprises 2 or 3 larger and vertically inflated (significantly larger than the tubercles in the mesial part) and 1 or 2 small, rounded tubercles (Fig. 2C) [vs. several isomorphically interspaced tubercles without a significantly larger one in Par. balssi, Par. daviei, Par. pilimana and Par. pilosa (Shih et al. 2020: figs. 2D, 4D, 6D)].</p></div>	https://treatment.plazi.org/id/F5111D13756DC645FF3BFD34FA404BA7	Public Domain	No known copyright restrictions apply.

VM34, Palikulo Peninsula, Sanma Province, Espiritu Santo Island, Vanuatu, 23 Sep. 2006 .</p><p>Remarks. In the collection of Parahelice from Vanuatu, there are an additional 3 specimens superficially similar to Par. ngankeeae . The 3 specimens form two closely related clades, sister to Par. ngankeeae based on the molecular analyses (Fig. 5; Table 2). One clade (Par. sp. 1) has 2 females (ZRC 2023.0245) that agree with the character of suborbital cristae of Par. georgei described in K. Sakai et al. (2006). Another clade (Par. sp. 2) with 1 male (ZRC 2023.0246) also conforms to the male characters of suborbital cristae, chelipedal manus, and male G1s of Par. georgei . Further study is necessary to confirm the identity of the two species.</p></div>	https://treatment.plazi.org/id/F5111D137568C644FF3BF89DFB974C5B	Public Domain	No known copyright restrictions apply.
