Type Series and Locality. Holotype, MSR 201, mature female, 354 mm TL, collected from Tanjong Sirik, Sarawak, Malaysia, 04°48’N, 109°56’E to 05°19’N, 111°16’E, in 118 and 165 m of water, collected July 2– 11, 1998.

Remarks. C ephaloscyllium parvum ( Inoue & Nakaya 2006) is considered a junior synonym of C. sarawakensis ( Yano et al. 2005) based on morphometric similarities and geographic distribution. It is clear from the striking color pattern, including the dark lateral blotches between the paired fins, that C. parvum and C. sarawakensis are one and the same. Juveniles have the striking color pattern of numerous dark polka-dots which fade upon reaching adulthood (see Fig. 16 View FIGURE 16 ; Inoue & Nakaya 2006, Fig. 3 View FIGURE 3 a; Yano et al. 2005, pl. 95; Chan 1966, Fig. 5 View FIGURE 5 ). We concur with the color pattern change with growth represented in Inoue and Nakaya (2006, Fig. 3 View FIGURE 3 ). We have compared a juvenile female specimen one of us (DAE) collected from Tungkang, Taiwan (CAS 224882) and conclude that this specimen is C. sarawakensis . Also, it is now understood that the specimens Compagno (1984) refers to as pseudo- umbratile from Hong Kong are in fact C. sarawakensis (L.J.V. Compagno, pers. comm.). Table 3 View TABLE 3 gives morphometric data concerning type material collected by both describing authors, and our juvenile.
