Figs 48-49, 51 , 65-69

Holotype: SMF; male; Philippines, Leyte, Visca, North Baybay, primary forest, 200-500 m; leg. W. Schawaller et al., 22.02.1991.

Other material examined: SMF; 1 male collected together with the holotype. – SMF; 2 females; Philippines, Leyte, Lake Danao, forest edge, 500 m; leg. W. Schawaller et al., 19.02.1991.

Diagnosis: Similar to C. rugosus , distinguished from this and other known congeners by distinctive shape of E (broad, lateral projection just below curved, hook-like tip; Figs 65-66 ), C (curved retrolateral margin, stout hooked tip; Figs 65-66 ) and RTA (tip beak-shaped; Figs 66-67 ). Females can be distinguished by the elongated/ oval spermathecae ( Figs 68-69 ).

Etymology: Named after the collector.

Description: Male: Total length: 3.6; prosoma length: 1.7, width: 1.7. Leg I: femur 2.1, patella 0.7, tibia 2.0, metatarsus 1.0, tarsus 0.7. Opisthosoma dorsally with irregular black, diffused spots, anteriorly with white spots, two pairs of brown circular spots towards the center, laterally black spots connecting to form bands ( Figs 48-49 ). Legs uniformly yellow-brown. Leg formula 1243, ALE> PLE> AME> PME, PME reduced, barely visible, PME less than 0.25 times PLE. AER and PER recurved, eyes on light brown-colored mounds, mounds of LE not touching. Palps as in Figs 51 , 65-67 . Cymbium lacking dorsal trichobothria.

Female: Total length: 3.8; prosoma length: 1.8, width: 1.8. Leg I: femur 2.0, patella 0.7, tibia 1.8, metatarsus 1.3, tarsus 0.9. In general similar to male. Epigynum and vulva as in Figs 68-69 .
