Cosmophasis valerieae Prószyński & Deeleman-Reinhold 2010 Figures 5 , 7 :6, 46-49, Map ( Figure 1 ) #58 This little-known, recently described species is known only from the southernmost islands of Indonesia ( Lesser Sunda ), from Java to East Nusa Tenggara . Prószyński & Deeleman-Reinhold (2010) designated a female holotype and a male allotype for this species, both from Samokat , Sumbawa Besar . Here ( Figures 46-49 ) we provide photographs of living C. valeriae to make it possible to recognize these in the field. Figure 46. Detailed views of the scales of an adult male Cosmophasis valeriae from Bali. 1, Dorsal view of eye region showing alternating bands of light blue and violet-gold iridescent scales. These scales are lanceolate and wavy. 2-4, Details from (1). 5-6, Two views of the scales covering the dorsal opisthosoma. Isolated tracts of blue, lanceolate, iridescent scales are surrounded by a dense array of black, round, and semi-transparent overlapping scales. Figure 47 (continued on next page).

Immature Cosmophasis valeriae from Bali. Both males and females have the colours of an adult female when immature. Diagnosis . Males ( Figure 47 ) resemble other, well-known species like C. thalassina and C. umbratica in most features, including the general appearance of the pedipalps, but they are otherwise readily identifiable. Instead of black, the transverse bands of the carapace are comprised of brilliant, violet-gold iridescent scales. The wide articulation of the carapace (clypeus) with the chelicerae is jet-black, interrupted by only a few white clypeal setae at the median. Instead of a long median tract of iridescent scales on the dorsal opisthosoma, there is a transverse band comprised of three fused circular patches of these scales. The dense array of overlapping, pitch-black scales that cover most of the opisthosoma can also be used to distinguish male C. valeriae . Females of this sexually dimorphic species ( Figure 48 ) are even more distinctive. The carapace is uniformly covered with vivid green (yellow to blue-green) iridescent scales, with some orange scales around the anterior eyes. Markings on the opisthosoma include a background of bright orange scales and resemble those of C. bitaeniata , but instead of a transverse band across the dorsal opisthosoma, three separate white spots, each outlined in black, are present. These spots are not fused as they are in the male. The epigynum of the female (Prószyński & Deeleman-Reinhold 2010) is also diagnostic. Immatures ( Figures 5 , 49 ) resemble the adult female. In Figure 5 you can see the detailed structure of the orange opisthosomal scales of this species. As in other Cosmophasis , the large, rounded scales that overlap to form a tight array are only found on the opisthosoma.
