Type material.
All from Malaysia: Sarawak: Mulu Nat. Pk. Holotype. Female (specimen IDWM.20011, in UBCZ), from Botanical Trail, 4.0380°N, 114.8137°E, 50 m el. 18 March 2012 W. Maddison WPM#12-059. Paratype female (specimen SWK12-1831, in UBCZ) from Botanical Trail, 4.0404°N, 114.8151°E to 4.0405°N, 114.8154°E, 50 m el. 16 March 2012 Maddison/Piascik/Ang WPM#12-039. Paratype. Male (specimen SWK12-M0009, in UBCZ) from Nightwalk Trail, 4.0446°N, 114.8154°E to 4.0450°N, 114.8156°E, 50 m el. 24 March 2012 Maddison/Piascik/Ang WPM#12-090. Paratype male (specimen JK.12.01.22.0024, in LKCNHM) from Sungai Paku Waterfall Trail, 04.0372°N, 114.8247°E, J. K. H. Koh 22 January 2012.
Etymology.
Latin, meaning bent backward, referring to both the RTA and the ridge in front of the epigynal openings. Other names: In Maddison (2015b) and WPM’s field or lab notebooks the informal code for this species was “BVMTT”. In J. Koh’s notebooks it was referred to as "Bent RTA".
Notes.
The living paratype male 12.01.22.0024 is shown as figure E on p. 203 of Koh and Bay 2019.
Diagnosis.
Male palp distinctive for bent RTA and thick curled embolus accompanied by TmA (Fig. 104 View Figures 104–112 ). Epigyne similar to that of I. redynis , with cavernous ECP, but with each opening framed by an anterior curved ridge. Posterior third of abdomen dark except for prominent pale transverse band just in front of anal tubercle. First femur pale basally, lacking dark spot of I. redynis .
Description.
Male (based on paratype, specimen SWK12-M0009). Carapace length 2.9; abdomen length 3.6. Carapace in alcohol dark brown except medium brown near fovea, and a small medium brown stripe medially on thoracic slope. Clypeus dark, glabrous, very narrow in middle, exposing a white arthrodial membrane beneath. Chelicerae dark, concave and with lateral ridge. At least four retromarginal teeth, on long sharp ridge. Palp pale except dark gray retrolateral face of femur. Embolus thick and curved, accompanied by similarly curved TmA (Figs 104 View Figures 104–112 , 106 View Figures 104–112 ). RTA projects out away from axis of palp, curved toward the proximal (Figs 105 View Figures 104–112 106). Legs strongly contrasting between the first legs (dark, except for patella, tarsus, and much of femur). Abdomen as described under Male-female matching.
Female (based on holotype, specimen IDWM.20011). Carapace length 3.2; abdomen length 4.1. Carapace dark brown, paler around fovea and in a narrow medial band on thoracic slope. Clypeus narrow, dark, glabrous, exposing white arthrodial membrane. Chelicerae vertical, concave in front. Five retromarginal teeth. Legs pale except for first leg, whose tibia and metatarsus are dark brown in the middle, and the femur which grades to dark brown terminally. Abdomen marked as described under Male-female matching. Epigyne (Figs 107 View Figures 104–112 , 108 View Figures 104–112 ) with large ECP medially. Openings behind arcing ridges.
Male-female matching.
The male and female, both collected at Mulu National Park, are matched primarily on the basis of markings and expected genitalic correlations. They share abdominal markings (Figs 110-112 View Figures 104–112 ): just in front of the anal tubercle is a prominent pale transverse mark, more prominent than in other species, and in front of the pale mark is a dark more or less unmarked area that extends to cover the posterior third of the abdomen. Just in front of that, in the middle third, are two uneven narrow broken longitudinal bands, besides which are similar uneven pale bands on the side. While other Indopadilla species have uneven longitudinal bands, no others known have the bands so restricted by a dark posterior third, nor have the pale pre-anal band so prominent. In genitalia, the large ECP is expected to correspond to a dramatic RTA, which the matched male has. A female was chosen as holotype as it is in best condition, and the molecular data are from a matching female.
