Female of <i>Asianopis naumenkoi</i> <b>sp. nov.</b> is most similar to this of <i>A. apo</i> <b>sp. nov.</b> by body coloration and structure of the copulatory organs but can be easily distinguished by barely visible humps on femora I–III (vs. well distinct and large, on femora I, III; cf. Figs 39–40 and 35–38), high median plate in posterior-ventral view (vs. low; cf. Fig. 47 and 51)and the smaller number of copulatory ducts turns (4 vs. 5; cf. Figs 46 and 50). From <i>A. luzonensis</i> the new species differs by the pattern of the lateral sides of abdomen (large, dark brown triangular spots medially vs. wide white bands anteriorly; cf. Fig. 41 and Barrion-Dupo & Barrion 2018: fig. 6D). For differences from species of the <i>liukuensis-</i> and <i>zhuanghaoyuni</i> -group, see Table 1.</p><p><b>Description.</b> Female.

PME also surrounded by black setae. Chelicerae yellow with few black spots anteriorly, 5 pro-, 4 retrolateral teeth and number of retrolateral denticles. Carapace light brown with distinct median band, lateral bands absent. Cephalic part covered with white plumose setae. Sternum yellow with light brown edges. Labium yellow. Endites dark brown with black spots.</p><p>Palpal femur yellowish; patella and tibia yellowish with black spots; cymbium yellowish. Legs coloration. Coxa yellowish gray; femora I–II brown with black ventral side proximally, III brown with black ventral side, IV brown, with black spots on ventral side; patellae I–II, IV light brown, III brown; tibiae I–II, IV light brown, III brown with black semi rings; metatarsi I–III brown, IV light brown; tarsi I–III brown, IV light brown. Сalamistrum represented by dense row of short black setae (Fig. 42). Calamistrum length/metatarsus length ratio ca. 0.27. Femora I–III with small humps (<i>Hp</i>) covered with strong short spines (<i>SP</i>, figs 39–40). Humps height/femur width ratio ca. 0.42.</p><p>Abdomen dorsally light brown, with thin, longitudinal dark brown stripe and number of tiny yellow spots forming longitudinal stripes. Sides of abdomen light brown with thin, yellow longitudinal stripes and large, dark brown triangular spots. Ventral part of abdomen yellow with dark brown longitudinal stripes and small irregular spots. Spinnerets dark brown.</p><p>Epigyne as in Figs 45–48. Median plate (<i>MP</i>) anchor-shaped in ventral view, trapezoidal posterio-ventrally, width/length ratio 4. Copulatory openings (<i>CO</i>) distinct. Copulatory ducts (<i>CD</i>) with four turns. Receptacles (Re) rounded, spaced by distance equal to their diameter. Receptacle duct (<i>RD</i>) narrow.</p><p>Male unknown.</p><p><b>Notes</b>. Currently, two species groups are distinguished in <i>Asianopis</i>: the <i>liukuensis</i> -group and the <i>zhuanghaoyuni</i> - group (Lin <i>et al.</i> 2020b). Since, based on the combination of characteristics, <i>A. naumenkoi</i> <b>sp. nov.</b> and <i>A. apo</i> <b>sp. nov.</b> cannot be assigned to either of the aforementioned groups, we propose to unite these new species into the <i>apo</i> - group. Although <i>A. labangan</i> and <i>A. luzonensis</i> show some similarity to the new species from the Philippines, we cannot confidently assign them to any species group until they are thoroughly redescribed.
