Cebrenninus rugosus .– Ramírez, 2014: 223, fig. 151d. Misidentification.
Holotype: MHNG; male; Indonesia, East Kalimantan Province, Berau District, 1 km off road Tanjungredeb to Tanjungselor, ca 45 km N of Tanjungredeb, 2°29′33″S, 117°28′46″E, 190 m, primary forest; 29.9.2008 to 3.10.2008; leg. P. Schwendinger (sample IND-08/07).
Other material examined: RMNH.ARA.17165; 1 male, 1 female, 6 juveniles; Indonesia, North Sumatra, Gunung Leuser, Bohorok, litter; 10.08.1982; leg. C.L. and P.R. Deeleman. – RMNH.ARA.17166; 6 males, 12 females; Indonesia, North Sumatra, Gunung Leuser, Ketambe; 2.-4.03.1986; leg. Suharto Djojosudharmo; second date given on label 3.-5.04.1986, trail 64; in addition to the above listed specimens, this sample contained several specimens of C. phaedrae sp. nov. – RMNH.ARA.17167; 8 males, 4 females; same locality and collector, lowland leaf litter; 01.05- 09.08.1986; in addition to the above listed specimens, this sample contained several specimens of C. phaedrae sp. nov. – MHNG; 2 males, 11 females, 9 juveniles, collected with the holotype (sample IND-08/07). – RMNH. ARA.15944; 1 male (damaged, opisthosoma missing, left palp missing); East Malaysia, Borneo, E. Sabah, Danum Valley Field Centre, primary forest, dung trap; 1991; leg. Andrew Davis.
Diagnosis: Similar to C. phaedrae sp. nov. and C. kalawitana comb. nov., distinguished from these and other known congeners by distinctive shape of E (broad base, slightly enlarged in the center, finely tapered towards tip, tip slightly enlarged; Figs 13, 15 View Figs 13 - 16 ), C (curved margins, hooked tip; Figs 13 View Figs 13 - 16 , 30 View Figs 27 - 34 ) and RTA (hooked tip; Figs 13-16 View Figs 13 - 16 , 31 View Figs 27 - 34 ). Females can be distinguished by the oval spermathecae and by the short CD that seems to be a bit longer than the width of the wall of the S ( Figs 33-34 View Figs 27 - 34 ). Moreover, both sexes of this species are larger and darker in color than C. phaedrae sp. nov.
Etymology: The species name is a noun in apposition taken from the name of the district in which the type locality lies.
Description: Male: Total length: 3.1; prosoma length: 1.5, width: 1.4. Leg I: femur 1.8, patella 0.6, tibia 1.7, metatarsus 1.2, tarsus 0.8. Prosoma red-brown, rounded, six eyes, PME absent, LE on light browncolored mounds, mounds distinct but not touching ( Fig. 4 View Figs 4 - 12 ). Opisthosoma dorsally with irregular black diffused spots, two pairs of brown circular spots towards the center, laterally black spots connect to form bands ( Fig. 4 View Figs 4 - 12 ). Legs uniformly yellow-brown. Leg formula 1243, ALE> PLE> AME, AER and PER recurved. Palps as in Figs 13-16 View Figs 13 - 16 , 30-31 View Figs 27 - 34 . Cymbium of the male palp lack trichobothria.
Female: Total length: 3.3-4.0; prosoma length: 1.5-1.7, width: 1.3-1.5. Leg I: femur 1.8, patella 0.5, tibia 1.5, metatarsus 1.0, tarsus 0.7. In general similar to male. Epigynum and vulva as in Figs 33-34 View Figs 27 - 34 . Spermathecae oval, CD short.
Distribution: Known from localities in northern Sumatra and eastern Borneo.
