Cupa kalawitana Barrion & Litsinger, 1995: 208 , fig. 119a-f. Type not examined.

Cebrenninus rugosus .– Tang et al., 2009. Misidentification.

Material examined: SMF 3636; 2 males, 2 females, 3 juveniles; Philippines, Luzon, Laguna Province, Mt Makiling; leg. Baker. – CASENT 9042005; 2 males, 1 female, 1 juvenile; Philippines, Luzon Island, Laguna Province, Malabo Camp, Mt Makiling, 3.46 km SSW of Los Baños, 673 m, 14°08.220′N 121°12.325′E, general collecting, daytime, forest; 10.- 12.05.2011, leg. H. Wood et al. – CASENT 9045699; 2 juveniles; Philippines, Luzon Island, Laguna Province, same locality as above, hand sorting, sifted litter in forest. – CASENT 9043491; 1 male; Philippines, Luzon Island, Laguna Province, Mt Makiling, 3.8 km WSW of Los Baños, 818 m, 14°08′20.1″N 121°11′55.0″E, general collecting, night time; 11.05.2011, leg. H. Wood et al. – CASENT 9047524; 1 male; Philippines, Luzon Island, Quezon Province, Mt Banahaw de Lucban, 3.78 km WSW of Lucban, 747 m, 14°05.859″N 121° 31.071E ″, general collecting, daytime, forest; 14.- 22.05.2011, leg. 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, 32 ), C (curved margins, hooked tip; Figs 27-28 ) and RTA (smooth, gradual tip; Figs 27,

29, 32). Females can be separated on the basis of their oval CO ( Fig. 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 22-23 ). Opisthosoma dorsally with irregular black, diffused spots, anteriorly with white spots, two pairs of brown circular spots towards the center ( Figs 22-23 ). Laterally the black spots connect to form bands ( Figs 22-23 ). 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 25 , 27-29, 32 . 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 21 , 24 ). Epigynum as in Fig. 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.
