H. Wood et al. – CASENT 9047526; 1 male, 1 female; same locality and collection data as above.

Diagnosis: Distinguished from other known congeners by distinctive shape of E (broad based, filiform, tapered towards the tip; Figs 27, 32View Figs 27 - 34), C (curved margins, hooked tip; Figs 27-28View Figs 27 - 34) and RTA (smooth, gradual tip; Figs 27,View Figs 27 - 34

29, 32). Females can be separated on the basis of their oval CO ( Fig. 26View Figs 23 - 26).

Description: Male: Total length: 3.6; prosoma length: 1.8, width: 1.7. Leg I: femur 2.3, patella 1.5, tibia 2.3, metatarsus 1.6, tarsus 0.9. Prosoma uniformly red-brown, rounded, with eight eyes ( Figs 22-23View Figs 17 - 22View Figs 23 - 26). Opisthosoma dorsally with irregular black, diffused spots, anteriorly with white spots, two pairs of brown circular spots towards the center ( Figs 22-23View Figs 17 - 22View Figs 23 - 26). Laterally the black spots connect to form bands ( Figs 22-23View Figs 17 - 22View Figs 23 - 26). Legs uniformly yellow-brown. Leg formula 1243, ALE> PLE> AME> PME, PME less than 0.25 times PLE. In some specimens PME reduced to two black spots. AER and PER recurved, eyes on light brown-colored mounds, mounds not touching. Palps as in Figs 25View Figs 23 - 26, 27-29, 32View Figs 27 - 34. Cymbium lacking trichobothria. The male of this species was described in detail by Barrion & Litsinger (1995).

Female: Total length: 4.3; prosoma length: 2.1, width: 1.8. Leg I: femur 2.2, patella 1.5, tibia 2.0, metatarsus 1.3, tarsus 1.0. In general similar to male ( Figs 21View Figs 17 - 22, 24View Figs 23 - 26). Epigynum as in Fig. 26View Figs 23 - 26.

Distribution: Known only from two mountains on Luzon Island, the Philippines.

Remarks: Cupa kalawitana  is here removed from the synonymy of C. rugosus  , proposed by Tang et al. (2009). Types have not been seen, however, most of the examined material is from localities very close to the type locality. All examined material could be clearly distinguished from C. rugosus  , as given in the diagnosis below, and are thus not considered conspecific with it.
