Ordo: Araneae
Familia: Salticidae
Genus: Eupoa
Name
Eupoa thailandica Logunov & Marusik, 2014 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type
Holotype 1♂ (MHNG) from Thailand, Trat Prov., Ko Chang, west side (12°03'N, 102°18'E), WINKLER-extraction in secondary forest with primary spots (AS-T-5), 50-200 m a.s.l., 3-23.12.1999, A. Schultz.
Paratypes: THAILAND: 2♂1♀ (MHNG, one male without abdomen and palp), together with the holotype.
Etymology
The species epithet originates from the country of origin of the type series.
Diagnosis
By having the massive compound terminal apophysis with a deep longitudinal groove on its apical edge (Fig. 109, 115), the male of Eupoa thailandica sp. n. is most similar to that of Eupoa pappi sp. n. (Fig. 67–68), from which it differs in having the smaller and more closed apical cavity of tegulum and the shape of tegular and compound terminal apophyses. The hook-shaped embolic tip of Eupoa thailandica sp. n. (Fig. 110) is unique among all the Eupoa species known to us. The female of Eupoa thailandica sp. n. has a characteristic, mushroom-shaped central epigynal plate (Fig. 117) and the distinct spermathecae (Fig. 118). Besides, both sexes of Eupoa thailandica sp. n. have a very characteristic colour pattern on the dorsum containing a large transverse brown spot at its rear end (Figs 85–86); of the Eupoa species known to us, only the female of Eupoa yunnanensis has got a similar colour pattern (Fig. 121).
Distribution
The type locality only.

MALE (the holotype). Measurements. Carapace 0.87 long, 0.73 wide and 0.54 high at PLE. Ocular area 0.56 long, 0.77 wide anteriorly and 0.66 wide posteriorly. Diameter of AME 0.24. Clypeus height 0.13, chelicera length 0.24. Abdomen 0.67 long, 0.50 wide. Length of leg segments: I: 0.50 + 0.21 + 0.33 + 0.30 + 0.21; II: 0.39 + 0.16 + 0.31 + 0.27 + 0.20; III: 0.39 + 0.17 + 0.26 + 0.27 + 0.18; IV: 0.67 + 0.26 + 0.47 + 0.36 + 0.23. Leg spination.

Carapace yellow, with a brownish marginal stripe at rear end and with brownish eye filed. Blackened around eyes. Clypeus naked, yellow. Sternum, maxillae, labium and chelicerae pale yellow. Abdomen pale yellow, but dorsum with a colour pattern consisting of two brown semi-rings in its fore-half and a transverse brown spot at the rear end (just in front of the spinnerets). Book-lung covers and spinnerets pale yellow. All legs and palps yellow. Palpal structure as in Figs 106–116: femur rather long and thin, almost equal to the length of cymbium; patellar apophysis medium-sized, fingerlike, with a dorso-basal bulge, reaching almost a third of the cymbial length; tibia with set of long hairs prolaterally, tibial apophysis hook-shaped, directed ventrad with its sharp tip bend upward and directed anteriorly; cymbium with a median, basal bunch of thick white hairs; tegulum well-developed; tegular apophysis not developed; median apophysis thin, directed ventrad and situated in the central part of tegulum; compound terminal apophysis massive, as a large, thick hook having a longitudinal groove on its dorsal edge; embolus coiled, making one and a half revolutions, its tip hook-shaped.
FEMALE. Measurements. Carapace 0.96 long, 0.77 wide and 0.54 high at PLE. Ocular area 0.59 long, 0.81 wide anteriorly and 0.69 wide posteriorly. Diameter of AME 0.24. Clypeus height 0.07, chelicera length 0.31. Abdomen 1.04 long, 0.91 wide. Length of leg segments: I: 0.54 + 0.21 + 0.36 + 0.34 + 0.20; II: 0.44 + 0.19 + 0.26 + 0.27 + 0.20; III: 0.41 + 0.17 + 0.30 + 0.31 + 0.21; IV: 0.73 + 0.22 + 0.59 + 0.43 + 0.25. Leg spination. Leg I: Tb v 2-2-2ap; Mt v 2-2-2ap. Leg II: Tb pr 0-1, v 1-2; Mt pr 1-1, rt 0-1-0, v 2-0-2ap. Leg III: Tb pr and rt 0-1-0; Mt pr and rt 0-1-0. Leg IV: Tb pr 0-1-0; Mt pr and rt 1-0-1ap. Coloration as the male, but the dark brown spot on dorsum is larger (Fig. 85). Epigyne and vulva as in Figs 117–118: central epigynal plate mushroom-shaped, sclerotized and contrastingly darker than the rest of epigyne; wide transparent insemination ducts; round receptacles that are spaced up.
