Material examined. One adult ♂ (HC-Ba1) was collected by the senior author ( THC) on a Ficus tree in Bali, 18 FEB 2016 . This specimen will be deposited in the Florida State Collection of Arthropods ( FSCA), Gainesville .

Artabrus erythrocepthalus are relatively large and robust salticids, close to 1 cm in body length. Unfortunately published descriptions of this species (C. L. Koch 1846; Simon 1903; Prószyński 1984, 1987, 2009; Prószyński & Deeleman-Reinhold 2010) are based only on a handful of specimens in alcohol that have lost the distinctive, bright green colour of the living animals. The original description of a ♂ by C. L. Koch (1846) is given here in Appendix 1. With no type specimen available, Prószyński (2009) designated a ♂ lectotype and a ♀ paralectotype for this species.

Males have a black eye-region surrounded by red or orange scales, black faces, and large, shiny black chelicerae. The face is covered with scattered white scales. Legs are usually bright, translucent green except for the darker brown distal segments of legs I and II. Some males have yellow-green legs ( Figure 4 View Figure 4 :7). Legs I bear ventral fringes comprised of black or off-white setae, primarily under the patella, tibia and metatarsus. The dorsal opisthosoma carries a pattern of orange and off-white scales. Although structure of the pedipalp has been used as an important character, this is not remarkable ( Figure 2 View Figure 2 ). In life ( Figures 3-4 View Figure 3 View Figure 4 ), adult males are easy to identify. Penultimate males closely resemble females and vary in general colour from light brown ( Figure 5 View Figure 5 ) to green as they develop, but all adults appear to be yellowgreen to green, and most are bright green.

Females, like immatures, are translucent and mostly green when resting on a green leaf, or brown ( Figures 6-7 View Figure 6 View Figure 7 ). Like males, they have a pattern of orange and off-white scales on the dorsal opisthosoma, laterally striated ( Figure 7 View Figure 7 :5). The eye region carries a distinctive pattern of white scales on a dark brown background, surrounded by orange scales.
