Eupoa schwendingeri sp. n. Figs 89-90, 97-105

Type.

Holotype 1♂ (MHNG) from northern Thailand, Chiang Mai Prov. and Distr., Doi Suthep-Pui National Park, Doi (=Mount) Suthep, 1180 m a.s.l., 1-30.03.1987, P. J. Schwendinger.

Paratypes: THAILAND: 2♀ (MHNG), together with the holotype; 1♂ (MHNG), northern Thailand, Chiang Mai Prov. and Distr., Doi Suthep-Pui National Park, near Pin Pak Pai Waterfall, 1155 m a.s.l., pitfall traps 10.01-11.02.1997, P. Dankittipakul.

Etymology.

The species is named in honour of our colleague, the well-known arachnologist, Dr Peter Schwendinger (Geneva, Switzerland), who collected the type series and who made the majority of the Eupoa specimens treated in the present work available to us.

Diagnosis.

The male palp of Eupoa schwendingeri sp. n. differs from those of all Eupoa species known to us in having the rather small and inconspicous median and compound terminal apophyses (Figs 97-99). The female of Eupoa schwendingeri sp. n. has the unique epigyne shaped as a square plate, with parallel sides (Fig. 100) and the entrances of insemination ducts directed to each other (Fig. 101). Besides, both sexes of this species have a very characteristic body colour pattern consisting of two longitudinal subparallel grey stripes on dorsum (Figs 89, 104-105).

Distribution.

The only locality in Thailand: Doi Suthep-Pui National Park.

Comments.

The ♂ paratype was lost after having been photographed, as the observation glass was incidentally dropped down to the floor. Thus, the ♂ paratype is represented by the male palp only (Figs 97-99) that is retained in the MHNG.

Description.

MALE (the holotype). Measurements. Carapace 0.90 long, 0.60 wide and 0.45 high at PLE. Ocular area 0.57 long, 0.73 wide anteriorly and 0.64 wide posteriorly. Diameter of AME 0.23. Clypeus height 0.04, chelicera length 0.30. Abdomen 0.88 long, 0.53 wide. Length of leg segments: I: 0.50 + 0.23 + 0.33 + 0.29 + 0.21; II: 0.40 + 0.16 + 0.23 + 0.26 + 0.20; III: 0.37 + 0.16 + 0.24 + 0.27 + 0.21; leg IV is missing. Leg spination. Legs I and II: no spines. Leg III: Mt pr 0-1-0. Leg IV is missing. Coloration (Figs 89-90, 104). Carapace yellow, with two wide longitudinal light brown bands. Eye field dark grey, blackened around eyes. Clypeus naked, yellowish brownish. Sternum, labium, maxillae and chelicerae light yellow. Abdomen yellow, with two longitudinal light grey stripes on dorsum. Book-lung covers light yellow. Spinnerets: anterior pair dark grey, posterior pair yellow. Leg I yellow, but femur (its distal part), patella, tibia and metatarsus with black pro-lateral longitudinal stripe, tibia and metatarsus also with light grey retro-lateral longitudinal stripe. Leg II yellow, but tibia ventrally with light grey longitudinal stripe. Legs III and IV yellow. Palps yellow, with brownish cymbia. Palpal structure as in Figs 97-99: patellar apophysis short, fingerlike; tibial apophysis thick and obtuse, directed ventrad with its tip bend dorsad; tegulum developed on its prolateral side only; tegular apophysis poorly developed, looking like an anterior ridge of tegulum; median apophysis spine-shaped, situated at the proximal end of tegulum; compound terminal apophysis poorly developed, looking like a hook-shaped process at the basal part of embolus; embolus coiled, making two revolutions.

FEMALE. Measurements. Carapace 0.98 long, 0.76 wide and 0.55 high at PLE. Ocular area 0.63 long, 0.79 wide anteriorly and 0.71 wide posteriorly. Diameter of AME 0.24. Clypeus height 0.07, chelicera length 0.29. Abdomen 0.90 long, 0.68 wide. Length of leg segments: I: 0.54 + 0.20 + 0.35 + 0.34 + 0.21; II: 0.50 + 0.20 + 0.26 + 0.29 + 0.21; III: 0.44 + 0.16 + 0.29 + 0.33 + 0.20; IV: 0.73 + 0.26 + 0.54 + 0.43 + 0.26. Leg spination. Leg I: Tb v 2-2-2ap; Mt v 2-2-2ap. Leg II: Tb pr 0-1, v 1-1; Mt v 2-2-2ap. Leg III: Tb pr and rt 0-1-0; Mt pr and rt 1-0. Leg IV: Tb pr and rt 0-1-0; Mt pr and rt 1-1. Coloration as in the male (Fig. 105), but palps and both pairs of spinnerets entirely yellow. Epigyne and vulva as in Figs 100-102: epigyne as square-shaped plate, with parallel sides; insemination ducts at their entrances directed to each other and then run posteriorly; receptacles small and pear-shaped.
