We consider that the new species should be placed in H. weddi group, which currently includes H. weddi, H. marchei, H. singaporensis, H. kula, H. armatus and H. schuhi. All the members of this group share the following characteristics: well developed trapezoidal to quadrate posterior metasternal process, male fore tibia with variations on a common basal armature consisting of multiple large teeth, and complex male endosoma with prominent lateral lobes (Polhemus &amp; Polhemus 2012). The new species can be easily distinguished from H. marchei, H. singaporensis and H. armatus by the trapezoidal shaped process on the posterior margin of the male metasternum; and can be distinguished from H. kula by the metasternum of the male not tumid posteriorly. Hermatobates lingyangjiaoensis sp. n. is closest in morphology to H. weddi and H. schuhi.</p> <p>Hermatobates lingyangjiaoensis sp. n. is similar to H. weddi in size and habitus, but it can be distinguished from the latter species by a) the posterior margin of the male trapezoidal shaped process on the male metasternum of H. lingyangjiaoensis sp. n. (~0.17) is wider than H. weddi (~0.10, based on an illustration in Polhemus &amp; Polhemus 2012, fig. 2F), (the ratio of width of the posterior margin of the trapezoidal shaped process on the male metasternum to width of the posterior margin of the male metasternum); b) the ventral side of the female middle femur with a row of ~12 black, very small teeth (Fig. 12), whereas in H. weddi, the middle femur has only a few tiny black teeth basally on the ventral margin; c) the color of the fore tibia is brown except for the middle part yellowish brown (Figs. 1–4, 7–9), whereas the fore tibia of H. weddi is yellowish brown except for the basal part brown; d) the antenna is blackish brown, the basal half to two-thirds of antennal segment I light yellowish brown (Figs. 1–4), whereas in H. weddi, the antenna is blackish brown with the basal third of segment I pale; e) the ventral side of the female fore femur bears a tooth which is larger and separated from the other teeth (Fig. 9), whereas in the female of H. weddi, the fore femur bears only a row of 15–18 small black teeth along the ventral margin.</p> <p>Hermatobates lingyangjiaoensis sp. n. is similar to H. schuhi in habitus, but it can be distinguished by a) individuals of the new species are distinctly smaller in both male (length 3.2–3.9 mm, width 1.6–1.9 mm) and female (length 3.3–3.4 mm, width 1.7–1.8 mm), whereas in H. schuhi, the male (length 4.0– 4.2 mm, width 1.7–2.0 mm) and female (length 3.55–3.60 mm, width 2.0– 2.1 mm) are larger; b) the papillae on the posteromedial metasternal process of the male are relatively sparse and somewhat elongate, whereas in H. schuhi, these papillae are very numerous but smaller and more rounded; c) the ventral side of the female middle femur has a row of ~12 black, very small teeth (Fig. 12), whereas in H. schuhi, the ventral side of the female middle femur has a row of ~7 black, very small teeth; d) the ventral side of the male middle femur bears a row of 24–34 small, black teeth (Figs. 10–11), whereas in H. schuhi, the ventral side of the male middle femur bears a row of 20–24 small teeth; e) the ventral side of the male fore femur bears a row of 10–14 small, black teeth (Figs. 7–8), whereas in H. schuhi, the ventral side of the male fore femur bears a row of 14–16 small, black teeth.</p> <p>Variation. Male individuals of this species have relatively large variations in the size of the fore leg, from moderately incrassate to less incrassate, and the greatest width of the fore femur is positively correlated to the length of body (the specific data of all seven males in mm, body length/greatest width of fore femur = 3.80/0.70, 3.78/0.65, 3.69/0.62, 3.65/0.66, 3.38/0.57, 3.30/0.42, 3.20/0.38). In moderately incrassate individuals, the depression between the bifid tooth and large tooth along the inner margin of the basal part of the fore tibia is subequal to the width of the large tooth (Fig. 7); and the same depression is approximately 2× the width of the large tooth in less incrassate individuals (Fig. 8). The width of the process on the posterior margin of the metasternum also varies among males.</p> <p>Etymology. This species is named after the Lingyangjiao Reef in the South China Sea, where the specimens were collected.</p> <p>Distribution. This species is so far known from only the type locality at Lingyangjiao Reef (= Antelope Island) in South China Sea. Lingyangjiao Reef is one of the reefs of the Yongle Islands (Figs. 27–28), The last author has made an intensive field survey around the Yongle Islands. However, Hermatobates was found only at Lingyangjiao Reef where individuals could regularly be collected.</p> <p>Biology. The biology and ecology of Hermatobatidae are poorly known and are based on the observations of Esaki (1947), Cheng (1977), Foster (1989), and Polhemus (1990). Esaki found Hermatobates living together with many Halovelia septentrionalis Esaki, collembolans, staphylinid beetles, and marine chironomid midges; Cheng found Hermatobates living together with Halovelia, collembolans, staphylinid beetles, and mites; Foster observed them feeding on recently dead adult chironomid midges; Polhemus found they were in company with various species of Halobates. Our specimens of Hermatobates were collected at an intertidal reef at low tide, without plants (Figs. 23–24). When the reef was exposed, Hermatobates appeared on the surface of shallow water, and could also be found under coral rocks (Fig. 25). The tidal range between high tide and low tide at the collecting locality was generally over one meter, and the reefs remain out of the water for no more than 8 hours. In the same habitat where Hermatobates were collected, many Halovelia, mites, and a few Halobates were also found. Hermatobates lingyangjiaoensis sp. n. was found preying on Halovelia sp. (Fig. 26), which is the first direct evidence of their feeding habit.</p> </div>	http://treatment.plazi.org/id/415EFA69FF977C63FF42FC3868E4FF33	Public Domain	No known copyright restrictions apply.
