Diagnosis: Similar to C. berau sp. nov., distinguished from this and other known congeners by distinctive shape of E (posterior half bottle-shaped, anterior half filiform, tip pointed; Figs 52-53), C (straight prolateral margin, broadest at midpoint, hooked tip; Figs 52-53) and RTA (tapering, pointed tip; Figs 52-54). Females can be distinguished by the round spermathecae, and by short CD not being longer than the width of the wall of S (Figs 55-56). Specimens of both sexes are smaller and lighter in color than specimens of C. berau sp. nov.
Etymology: Named after the ancient Greekmythological figure Phaidra.
Description: Male: Total length: 2.5; prosoma length: 1.4, width: 1.1. Leg I: femur 1.2, patella 0.3, tibia 1.0, metatarsus 0.7, tarsus 0.5. Prosoma red-brown, rounded, six eyes, PME absent, LE on light brown-colored mounds, mounds distinct but not touching (Fig. 46). Opisthosoma dorsally with irregular black diffused spots, two pairs of brown circular spots towards center, laterally black spots connected to form bands (Fig. 46). Legs uniformly yellow-brown. Leg formula 1243, ALE> PLE> PME. AER and PER recurved. Palps as in Figs 52-54. Cymbium without trichobothria.
Female: Total length: 2.3; prosoma length: 1.2, width: 1.1. Leg I: femur 1.0, patella 0.3, tibia 1.0, metatarsus 0.7, tarsus 0.5. In general similar to male. Epigynum and vulva as in Figs 55-56. Spermathecae rounded, CD short.
