Savarna thaleban Huber, 2005: 77  , Fgs 124–126, 131–134 ( Ƌ ♀).

Diagnosis

Easily distinguished from known congeners by morphology of male palp (shape of bulbal apophysis; tip of procursus; Fgs 131–132 in Huber 2005), and by female external and internal genitalia (epigynal plate without median or lateral processes, posterior margin evenly curved; pore plates oval, not contiguous; Figs 30–31View Figs 28 – 35, 42–43View Figs 36 – 43); from S. tessellata  and S. miser  also distinguished by black marks laterally on carapace ( Fig. 9View Figs 8 – 13).

Material examined

Holotype

THAILAND: Ƌ, Satun Province, Thale Ban National Park (6°42.5’N, 100°10’E), 270 m a.s.l., 15–18 Oct. 2003, ATOL Expedition 2003 leg., MACN, examined ( Huber 2005)GoogleMaps  .

Other material

THAILAND: 8 ♀♀, 6 juvs, same data as holotype ( MACN; see Huber 2005)GoogleMaps  ; 6 ƋƋ, 9 ♀♀, 3 juvs, Thale Ban National Park (6°43.58’ N, 100°09.74’ E), forest and cave entrance , near ground among rocks , 100 m a.s.l., 5 Mar. 2015, B.A. Huber & B. Petcharad leg., ZFMK ( Ar 12993, 12994)GoogleMaps  ; 3 ƋƋ, 3 ♀♀, same data ( PSUZC)GoogleMaps  ; 1 Ƌ, 1 ♀, 2 juvs, in pure ethanol, same data, ZFMK ( Mal 326)GoogleMaps  .

Amendments to original description

Male clypeus with pair of small lateral processes at rim ( Fig. 55View Figs 55 – 62). Male gonopore without epiandrous spigots. Male and female ALS with only two spigots each ( Fig. 61View Figs 55 – 62). In the palp illustrated in the original description ( Huber 2005: Fgs 131–132), the bulb is rotated about 180° from its natural position. In the natural position, the long bulbal process is directed in the opposite direction and the proximal bulbal sclerite is visible in prolateral view. All males seen without leg spines; prolateral trichobothrium absent on tibia 1, present on other tibiae; male and female tarsus 4 with single row of ventral comb-hairs ( Fig. 62View Figs 55 – 62). Tibia 1 in 8 males: 4.5–5.4 (mean: 5.0); in 9 females: 4.2–4.9 (mean 4.5).

Natural history

All specimens were found in the forest outside a small cave, in domed webs among rocks close to the ground. Spiders were abundant but Fed very rapidly, dropping from the web to the ground and becoming essentially invisible.

Distribution

Known only from the type locality ( Fig. 1View Fig 1).
