A new genus of the spider family Deinopidae C.L. Koch, 1850 is described from Asia: Asianopis Lin & Li gen. nov., with A. zhuanghaoyuni Lin & Li sp. nov. as the type species. The new genus is divided into two species groups, of which the liukuensis-group includes two species: A. dumogae (Merian, 1911) sp. reval. comb. nov. (♀) and A. liukuensis (Yin, Griswold & Yan, 2002) comb. nov. (♂♀); and the zhuanghaoyuni-group comprises five species: A. celebensis (Merian, 1911) comb. nov. (♂), A. konplong (Logunov, 2018) comb. nov. (♂), A. wangi Lin & Li sp. nov. (♂♀), A. wuchaoi Lin & Li sp. nov. (♂♀), and A. zhuanghaoyuni Lin & Li sp. nov. All previously described species are transferred from Deinopis MacLeay, 1839. Deinopis scrubjunglei Caleb & Mathai, 2014 is treated as a junior synonym of Asianopis liukuensis comb. nov.
New combination, new species, species groups, systematics, taxonomy
The spider family Deinopidae C.L. Koch, 1850 (Araneae, Deinopoidea), known as net-casting or ogre-faced spiders, is a small family that consisted of two genera and 64 species prior to the current study (
Ten species of Deinopidae were known from Asia: Deinopis aruensis Roewer, 1938 (♀) and D. celebensis Merian, 1911 from Indonesia; D. fasciculigera Simon, 1909 (♀) and D. konplong Logunov, 2018 (♂) from Vietnam; D. scrubjunglei Caleb & Mathai, 2014 (♂♀) from India; D. gubatmakiling Barrion-Dupo & Barrion, 2018 (juvenile), D. labangan Barrion-Dupo & Barrion, 2018 (♀), and D. luzonensis Barrion-Dupo & Barrion, 2018 (♀) from the Philippines; D. kollari Doleschall, 1859 (♂) from Myanmar and Malaysia; D. liukuensis Yin, Griswold & Yan, 2002 (♂♀) from China. Here, we describe a new genus and three new species, and present a molecular phylogenetic analysis of these spiders.
All specimens were preserved in 80% ethanol. Metatarsi and tarsi were removed for preservation in 100% ethanol for subsequent molecular work. Epigynes were cleared in proteinase K at 56 °C to dissolve non-chitinous tissues for three hours. Specimens were examined under a LEICA M205C stereomicroscope. Photomicroscope images were taken with an Olympus C7070 zoom digital camera (7.1 megapixels). Laboratory habitus photographs were taken with a Canon 5D Mark III digital camera equipped with a Canon MP-E 65 mm lens. Photos were stacked with Helicon Focus (version 6.7.1) or Zerene Stacker (version 1.04) and processed in Adobe Photoshop CC 2018. Photographs of Asianopis celebensis comb. nov. were taken by a KEYENCE. Photographs of Asianopis liukuensis comb. nov. from India (i.e., the type materials of D. scrubjunglei) were taken using a Leica DFC500 HD camera mounted on a Leica M205A stereomicroscope.
All measurements are in millimetres. Eye sizes are measured as the maximum diameter from either the dorsal or frontal view. Leg measurements are given as follows: total length (femur, patella+tibia, metatarsus, tarsus). Copulatory duct turns are defined by the number of apparent loops on the lateral margin of the copulatory/fertilization duct complex in dorsal view. The length of the embolic tip fold is measured as from the beginning of the fold to the embolic tip (Fig.

Asianopis zhuanghaoyuni Lin & Li, sp. nov.
The generic name is a combination of the word “Asia”, referring to the distribution of the genus, and the generic name Deinopis. The gender is feminine.
Asianopis gen. nov. can be easily distinguished from Deinopis by the following characters: a prominent setal fringe can be found above the posterior median eyes in both sexes of Asianopis species (Fig.
Prosoma (frontal view, upper ♂, lower ♀) (A–D), chelicerae (E–H) and leg I (I–J). Figures A and C modified from
Male. Total length 12.14–16.10 (n = 8), carapace pear-shaped, yellow-brown (liukuensis-group) or brown (zhuanghaoyuni-group) with white edge, white line extending from cephalic area to posterior margin and small spines sparsely distributed; fovea longitudinal, indistinct. Chelicerae with a promarginal tooth and one or two retromarginal teeth (liukuensis-group) or with four promarginal teeth and 2–6 retromarginal teeth (zhuanghaoyuni-group), no denticles. Endites and labium brown, distally white; sternum diamond-shaped, brown with median light band and few small spines. Legs brown, ventrally with black pattern and short spines, leg formula 1243. Opisthosoma cylindrical, brown or dark-brown with small black spots and irregular pattern. Cribellum entire, spinnerets brown (Figs
Female. Total length 14–24 (n = 13). Chelicerae with four promarginal teeth and seven retromarginal teeth, many denticles in between the promarginal and retromarginal teeth (liukuensis-group) or four promarginal teeth and 8–13 retromarginal teeth, without denticles (zhuanghaoyuni-group). Appearance of carapace, opisthosoma and legs as in male but femora of legs I enlarged basally (liukuensis-group) (Fig.
Male palpal tibia longer than cymbium; cymbium almost round; tegulum distinctly wider than the diameter of embolic coil (liukuensis-group) or tegulum obscured by embolic coil (zhuanghaoyuni-group) (Figs
Epigyne with anchor-shaped median plate, CO distinct, CD with three turns, S oval, SpD consistently wide (liukuensis-group) or with a well-developed MP, obscuring CO, CD with 7–8 turns, S oval, SpD consistently thin (zhuanghaoyuni-group).
The molecular phylogenetic analysis indicates with strong support that all the species in this study do not belong to Deinopis. Based on the 4893 bp-aligned sequences of seven gene fragments, the ML and Bayesian analyses produced the same topology, showing a split of a Southwest China clade from other clades and is strongly supported (Bootstrap value: 88; PP: 0.98) (Fig.
All the species of Asianopis gen. nov. were collected from bushes in low-elevation forests.
This new genus comprises two species groups: the liukuensis-group with two species: A. dumogae (Merian, 1911) sp. reval. comb. nov. and A. liukuensis (Yin, Griswold & Yan, 2002) comb. nov. and the zhuanghaoyuni-group with five species: A. celebensis (Merian, 1911) comb. nov., A. konplong (Logunov, 2018) comb. nov., A. wangi sp. nov., A. wuchaoi sp. nov., and A. zhuanghaoyuni sp. nov.

This species can be distinguished from A. liukuensis comb. nov. by the MP nearly covering the CO, S round, and the overall equal thickness of the CD (Figs

Type materials of D. scrubjunglei syn. nov. were examined and no differences between A. liukuensis and D. scrubjunglei were observed. Thus, we consider D. scrubjunglei to be a synonym of A. liukuensis, and the figures of D. scrubjunglei are given for comparison (Figs

The male can be distinguished from other congeners by having the distal lobe of the MA distinctly smaller than the basal lobe; in other Asianopis spp., the distal lobe is slightly smaller than the basal lobe (Fig.

The species is named after Mr Dongdong Wang, the collector of the holotype; noun (name) in genitive case.
The males resemble A. zhuanghaoyuni sp. nov. but can be distinguished from other species by the ratio of the length of the embolic opening to the length of the embolic tip fold, which is 1:6 in A. wangi sp. nov. and 1:8 in A. zhuanghaoyuni sp. nov. The fold is more developed in A. wangi sp. nov. (Fig.

The males resemble A. konplong (Logunov, 2018) comb. nov. but can be distinguished by the embolus originating at five o’clock in A. zhuanghaoyuni sp. nov. (9 o’clock in A. konplong (Logunov, 2018) comb. nov.); the ratio of the length of the palpal tarsus to the length of the cymbium is 11:9 in A. zhuanghaoyuni sp. nov., while in A. konplong (Logunov, 2018), comb. nov. it is 1:1 (Figs
