Diagnosis

Distinguished from closest known relative ( A. omayan ) by male clypeus modification ( Fig. 191 View Figs 189–194. — 189–193 ; apophyses closer together), distinct ventro-distal apophysis on male palpal femur ( Fig. 190 View Figs 189–194. — 189–193 ; only indistinct hump in A. omayan ), and shape of epigynum ( Fig. 213 View Figs 213–218 ; whitish areas smaller and wider apart). Distinguished from other congeners by bipartite retrolatero-ventral process on procursus ( Fig. 190 View Figs 189–194. — 189–193 ), male palpal trochanter with prolateral apophysis ( Fig. 189 View Figs 189–194. — 189–193 ; other species with only ventral apophysis), and pair of internal sclerotized pockets in female genitalia ( Figs 192–193 View Figs 189–194. — 189–193 ).

Etymology

Named for Philippine-born cosmopolitan artist Pacita Abad (1946–2004), famous for her vibrant, colorful abstract work, but also for her paintings of tropical flowers and animal wildlife.

Description

Male (holotype)

MEASUREMENTS. Total body length 3.4, carapace width 1.4. Leg 1: 44.3 (10.6 + 0.6 + 10.6 + 19.2 + 3.3), tibia 2: 6.6, tibia 3: 4.5, tibia 4: 6.5; tibia 1 L/d: 80. Distance PME-PME 430 µm, diameter PME 140× 155 µm, distance PME-ALE ~ 40 µm; AME absent.

COLOR. Carapace ochre-yellow with narrow lateral marginal bands and wide dark brown median band including ocular area and clypeus; sternum ochre-yellow, with darker triangular mark posteriorly and dark labium; legs ochre-yellow with slightly darker rings on femora (subdistally, with light tip), and tibiae (proximally and subdistally, the latter followed by light tip); abdomen ochre-gray, dorsally and laterally covered with many black marks, ventrally with dark mark behind gonopore.

BODY. Habitus as in Fig. 178 View Figs 178–188 ; ocular area raised, each triad on additional short hump directed toward lateral, without process below ALE ( Fig. 191 View Figs 189–194. — 189–193 ); carapace with very shallow median furrow in anterior part only; clypeus with distinctive pair of apophyses ( Fig. 191 View Figs 189–194. — 189–193 ); sternum wider than long (0.95/0.65), unmodified.

CHELICERAE. As in Fig. 191 View Figs 189–194. — 189–193 , with pair of lateral processes proximally and pair of long lateral apophyses distally; without modified hairs; without stridulatory ridges.

PALPS. As in Figs 189–190 View Figs 189–194. — 189–193 ; coxa unmodified; trochanter with ventral and prolateral apophyses; femur with retrolateral hump, large prolateral apophysis, and ventro-distal apophysis; patella triangular in lateral view; tibia with retrolateral trichobothrium in very distal position; proximal part of procursus with bipartite retrolatero-ventral process, with complex and apparently partly hinged distal elements; bulb with only one process (weakly sclerotized embolus), distally with indistinct hump, without small knobs.

LEGS. Without spines; with curved hairs on metatarsi 1–3; few vertical hairs; retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~25 pseudosegments, only distally distinct.

Male (variation)

Tibia 1 in six other males: 9.8–10.6 (mean: 10.2). Dark spot behind gonopore absent in two males. Abdomen with or without additional white spots in dorso-lateral rows. Male from Casaroro Falls with large light brown mark on sternum posteriorly.

Female

In general similar to male but clypeus unmodified and more homogeneously dark brown; eye triads much closer together (distance PME-PME 165 µm); with indistinct stridulatory apparatus between carapace and abdomen: small modified area medially on carapace ( Fig. 186 View Figs 178–188 ) versus barely distinguishable hairless area on abdomen. Tibia 1 in 13 females: 7.8–8.8 (mean: 8.1). Epigynum large sclerotized plate with pair of light lateral humps ( Figs 192 View Figs 189–194. — 189–193 , 195 View Figs 195–203. — 195–197 , 213 View Figs 213–218 ), with pair of very indistinct membranous pockets behind epigynum in weakly modified cuticle (weak transversal ridges) ( Figs 192 View Figs 189–194. — 189–193 , 195–196 View Figs 195–203. — 195–197 ). Internal genitalia as in Figs 193 View Figs 189–194. — 189–193 and 215 View Figs 213–218 , with distinct pair of sclerotized pockets.
