Type material.
All from Malaysia: Sarawak: Lambir Hills Nat. Pk., and in UBCZ. Holotype male (specimen IDWM.20007) from Bukit Pantu Trail, 4.2035°N, 114.0304°E to 4.2039°N, 114.0303°E, 210 m el. 5 April 2012 Maddison/Piascik/Ang WPM#12-136; paratype female (specimen SWK12-4350) from Lepoh-Ridan Trail, 4.2019°N, 114.0278°E to 4.2019°N, 114.0275°E, 190 m el. 2 April 2012 Maddison/Piascik WPM#12-125; paratype male (specimen SWK12-4688) from Inoue Trail, 4.2000°N, 114.0353°E to 4.2002°N, 114.0350°E, 190 m el. 4 April 2012 Maddison/Piascik/Ang WPM#12-128; paratype female (specimen IDWM.20008) from Bukit Pantu Trail, 4.2035°N, 114.0304°E to 4.2039°N, 114.0303°E, 210 m el. 5 April 2012 Maddison/Piascik/Ang WPM#12-136.
Etymology.
From the Malay word Padillothorax badut , meaning clown. In the field we called these (and P. mulu ) the "banded clowns". Other names: In Maddison (2015b) and WPM’s field or lab notebooks this species was grouped with P. mulu under the informal name “BVBND”, until it was distinguished from that species as “BVBND-L”.
Diagnosis.
Very similar to P. mulu , differing most notably in details of genitalia. The embolus of P. badut lacks the prolateral basal ridges and has a longer terminal part; the epigyne has the openings hidden beneath a fold.
Notes.
This and the other new Malaysian species ( P. mulu ) are very similar in appearance, thin and banded; together we consider them as the P. badut species group. When the first legs are held forward in life (e.g., Fig. 174 View Figures 168–175 ), the spider appears as a series of transverse white bands approximately evenly spaced from anterior to posterior: the first leg annuli, the two transverse bands on the carapace, and the four transverse bands on the abdomen. Their bodies are more delicate and parallel-sided than other Padillothorax , and they have more complex emboli.
Description.
Male (holotype, specimen IDWM.20007). Carapace length 2.3; abdomen length 3.1. Carapace (Fig. 172 View Figures 168–175 ): Black to dark brown except for band just back of the anterior eye row, and the pale trapezoidal window on thorax. Unusually flat (carapace height 0.72), with ocular area and most of the thorax on a plane, declining suddenly only near back of thorax. Fovea well behind the PLEs (by more than their diameter). Clypeus very narrow, dark. Chelicerae vertical, glabrous, dark. Teeth not examined in holotype, but another male from Lambir Hills has five retromarginal teeth, together in a mound as in P. semiostrinus . Palp pale except for base of femur. Base of embolus with two peaked projections on the retrolateral side (Fig. 168 View Figures 168–175 ). Endite with lateral lobe (Fig. 10 View Figures 4–35 ). Legs: First legs very distinctly longest and darkest, red-brown to black except for strong annulae with white scales. Legs II-IV pale yellow with just a smudge of dark laterally on a few segments of the fourth leg. Abdomen: narrow, with four white transverse bands.
Female (paratype, specimen IDWM.20008). Carapace length 2.1; abdomen length 3.1. Colour and structure matches that of male in nearly all aspects, with the most distinct difference being the slightly shorter first legs. Cheliceral teeth not examined in this specimen, but another female from Lambir Hills has four retromarginal teeth, together in a mound. Epigyne (Fig. 170 View Figures 168–175 ) with two anterior openings, hidden under folds, and simple copulatory ducts visible without clearing. The copulatory duct has a diverticulum for the accessory gland extending laterally just before entering the simple spermatheca.
Natural history.
On large-leaved understory plants such as palms. In life, they often hold the front legs out or to the front.
