Diagnosis
Distinguished from closest known relative ( A. indah Huber , sp. nov.) by shape of prolatero-ventral apophysis of male palpal femur ( Fig. 145 View Figs 145–149 ; pointed tip much shorter), by distal cheliceral apophyses ( Fig. 147 View Figs 145–149 ; more pointed and gradually narrowing), and by female genitalia ( Figs 148 View Figs 145–149 , 172 View Figs 163–177 ; pair of dark lines; posterior rim curved toward posterior); from all other relatives also by strong apophysis prolateroproximally on male palpal femur ( Fig. 145 View Figs 145–149 ; present but smaller in A. indah Huber , sp. nov.).
Etymology
Named for the type locality; noun in apposition.

Description
Male (holotype)
MEASUREMENTS. Total body length 2.6, carapace width 1.1. Leg 1: 26.9 (6.4 + 0.4 + 6.4 + 11.2 + 2.5), tibia 2: 3.8, tibia 3: 2.7, tibia 4: 4.0; tibia 1 L/d: 63. Distance PME-PME 455 µm, diameter PME 105 µm, distance PME-ALE 35 µm; AME absent.
COLOR. Carapace pale ochre with black lateral bands and wide brown median band including ocular area. Clypeus pale ochre with pair of brown marks at rim. Sternum medially ochre, laterally slightly darker. Legs ochre to light brown, indistinct darker rings on femora (subdistally) and tibiae (proximally and
subdistally); tips of femora and tibiae whitish. Abdomen grey with dorsal and lateral pattern of black and indistinct white marks; ventrally with small brown mark near spinnerets and in genital area.
BODY. Habitus as in Figs 107–108 View Figs 105–110 ; ocular area slightly raised, each triad on short stalk directed toward lateral; carapace without thoracic furrow (only dark line in anterior part); clypeus slightly more protruding than usual; sternum wider than long (0.75/0.55), unmodified.
CHELICERAE. As in Fig. 147 View Figs 145–149 , with pair of proximal lateral apophyses and pair of simple distal apophyses in very lateral position; without modified hairs; without stridulatory ridges.
PALPS. As in Figs 145–146 View Figs 145–149 ; coxa unmodified; trochanter with slender ventral apophysis with very small teeth prolaterally; femur with rounded retrolatero-ventral apophysis, long prolatero-ventral apophysis with side branch, with two prolateral processes, one of them very close to trochanter. Procursus complex; retrolatero-ventral process with bifid tip. Bulb simple, with short and wide embolus.
LEGS. Without spines, with curved hairs dorsally on metatarsi 1 and 2 only (mostly on proximal half), with few vertical hairs; retrolateral trichobothrium on tibia 1 at 3.5%; prolateral trichobothrium absent on tibia 1, present on other tibiae. Tarsus 1 with ~30 pseudosegments, distally fairly distinct.
Male (variation)
Tibia 1 in 4 other males: 6.1, 6.9, 7.1, 7.5; most males with distinct white marks on abdomen.
Female
In general similar to male; triads closer together (distance PME-PME 200 µm), not on stalks; clypeus less protruding; no curved hairs on metatarsi; abdomen with continuous ventral dark band between epigynum and spinnerets. Tibia 1 in 12 females: 4.2–5.8 (mean 5.1). Epigynum large brown plate ( Figs 148 View Figs 145–149 , 172 View Figs 163–177 ), slightly protruding, with distinctive lighter median area bordered by dark lines (parallel or converging anteriorly), with internal sclerites visible through cuticle. Internal genitalia as in Figs 149 View Figs 145–149 and 174 View Figs 163–177 , apparently without sclerotized pockets, with pair of lateral membranous pockets.
Natural history
The spiders were found close to the ground in small holes and cavities. They barely reacted to disturbance and were very easy to take from their webs. They share the locality with A. kinabalu , which lives higher among the vegetation.
Distribution
Known from two localities in Mt. Kinabalu area only ( Fig. 5 View Fig ).
