Phan leg.</p><p>Paratypes. 1 ♂ (immature), 2 ♀♀ (immature), same data as holotype.</p><p>Type deposition. All type specimens of the new species are deposited in the Zoological Collection (ZCDTU) of Duy Tan University, Danang, Vietnam.</p><p>Etymology. The first author chose the specific name “hopkinsi ” after Mr. Paul Hopkins (England, born in 1961) to whom he is grateful for his collaboration in the field trip.A noun in genitive case. Paul Hopkins was present in the discovery of this species and has made significant contributions to the knowledge of Odonata in the region.</p><p>Description of the holotype. Head (Figs 3–4). Labium pale yellow, tip with movable hooks black. Labrum, anteclypeus, postclypeus, mandibles and genae whitish, lower margin of labrum shining black. Frons matte black. Base of antennae black, the second segment brown, the third one yellow with a black apical ring, remaining segments entirely black. All ocelli with yellow ring. Epicranium matte black with a dark yellow occipital bar and two postocular spots. Occipital ridge black, either end with a small but distinct sharp spine. Eyes shining green with black spot dorsally in living specimens (Fig. 17).</p><p>Thorax (Figs 1, 7, 9). Anterior pronotal lobe yellowish, slightly prominent in lateral view; middle and posterior pronotal lobe dorsally dirty black, distal margin of posterior pronotal lobe yellowish; posterior margin structurally simple, rounded posteriorly. Synthorax black except for a large dorsal yellowish stripe along the median suture, a pale mesepimeral stripe and another yellowish stripe on lower margin of metepimeron.</p><p>Legs (Fig. 1). Coxae and trochanter yellow; femur yellow speckled with black in its flexor surface; tibia dark yellow; tarsus yellow; claws and armature black.</p><p>Wings (Fig. 1) hyaline; Px 14 in all wings. Pterostigma brown, rectangular shaped, covering one under cell.</p><p>Abdomen (Fig. 1). Dorsal half of S1–2 black, the remainder yellow; dorsum S2 with a short yellow stripe; S3–7 black, posterior 1/5 th pale yellow; S8 black with basal part pale yellow; S9 with a large pale yellow marking, connecting to a small anterior part of S8; S10 entirely black.</p><p>Genital ligula (Fig. 16). Simple structurally, the tip with two short apical flagella each curved distally.</p><p>Anal appendages (Figs 13–15) black. In lateral view, cerci longer than paraprocts, strongly curved downward, blunt apically, with two dorsal tubercles near apex; paraprocts thick, slightly up curved, apically with short golden setae, ventrally with long, sharp golden setae (Fig. 13). In dorso-lateral view, cerci broad mid-apically; paraprocts curved inward, apices forming a slipper-shaped, cup-like structure bearing a long distal spine (Fig. 14). In ventral view, paraprocts broad, sharply pointed, resembling a bird’s beak (Fig. 15).</p><p>Measurements (in mm). Hind wing 25; abdomen (including appendages) 49.</p><p>Description of paratype female. Color pattern as in holotype male (Figs 2, 5, 6, 8, 10), except for the large yellow marking, covering most of S9 (Figs 11–12). Wings with 14–15 Px in both wings (Fig. 2). Cerci conicalshaped, and stylus black; ovipositor pale yellow, remainder black (Fig. 11).</p><p>Measurements (in mm). Hind wing 25; abdomen (incl. appendages) 38.</p><p>Variation in paratype male and female. Although paratypes are immature specimens, the body coloration of the paratype specimens are similar to the holotype male and the female paratype used for description. Synthorax of these specimens are slightly deformed.</p><p>Differential Diagnosis</p><p>The new species differs from all congeners in the Protosticta trilobata group by the combination of having a yellow stripe on the medial suture of the dorsal synthorax, both in male and female (Figs 9–10) and apical part of male’s paraprocts of the new species is also identical with uniquely bird-beak-shaped (Fig. 14). In other members of the group, for instance, P. beaumonti (Phan &amp; Kompier 2016: fig. 1C), P. caroli (Phan &amp; Kompier 2016: fig. 2E), P. nigra (Phan &amp; Kompier 2016: fig. 5E), P. socculus (Phan &amp; Kompier 2016: fig. 7E), the distal spine is slender rather than robust and bird-beak-shaped as in P. hopkinsi (Fig. 14). The female of P. hopkinsi can be separated from the females of most species in the Protosticta trilobata group by the combination of following characters: anterior pronotal lobe yellowish while middle and posterior pronotal lobes black (Fig. 8); synthorax with a yellowish stripe and large yellowish marking on S9 (Figs 10–13).</p><p>Habitat and Ecology. The new species was found only on both sides of the trail leading to the waterfall in the Bidoup Nui Ba National Park, about 10–15 meters from it. Although we carefully surveyed along both sides of the stream, no individuals were detected there; they were only observed outside the waterfall area. They were found in dense bushes on the steep banks at the side of the trail and very difficult to spot. Thien Thai Waterfall is a large stream (about 5–10 meters width) with a strong current and a substrate of rocks and sand, with dense evergreen forests in high altitude area. This is also the first Protosticta species recorded at an elevation above 1,500 m altitude in Vietnam.</p><p>Distribution.

Our results show that three species— P. trilobata, P. nigra, and P. satoi —are restricted to the northern region (Figs 19–20), while P. linnaei, P. hopkinsi, and P. proboscis are confined to the Central Highlands (Fig. 20). Among these, P. satoi is widespread in the north and has also recently been recorded from several localities in Thanh Hoa, Nghe An, and Ha Tinh provinces of the North Central Coast (Phan, pers. database). In contrast, P. socculus is mainly distributed across the South-Central Coast and the Central Highlands (Fig. 19), whereas P. pseudocuriosa is known only from the North Central Coast (Fig. 20). Protosticta caroli appears to have the broadest range, occurring from the North through the Centre and into the Central Highlands (Fig. 19). Identification keys to the Protosticta trilobata group are provided in Kompier (2016, 2018), but it should be noted that Protosticta curiosa Fraser, 1934 in those keys has since been redefined as P. trilobata by Phan et al. (2022).</p></div>	https://treatment.plazi.org/id/022C87CDFFB23A40559C1F9AD9B3CE20	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
