Etymology. ReferS to the color pattern Similar to the angelfiSh Centropyge bicolor (Bloch).
Remarks. Lepidocyrtoides bicolorangelus sp. nov. reSembleS L. bicolor YoShii & Suhardjono, 1992 from Maluku ISland, IndoneSia by color pattern preSent on body poSteriorly including femur III and manubrium, reduced dorSal chaetotaxy and dorSal denS with 1 proximal blunt ciliate chaeta (See YoShii & Suhardjono, 1992: 17).
However, L. bicolorangelus sp. nov. iS eaSily diStinguiShed from thiS SpecieS by dorSal chaetatoxy of Th II with 4 poSterior mac (6 in L. bicolor), and Th III–Abd II with 0, 1(lateral) and 3 median mac reSpectively, while in L. bicolor iS 2, 0 and 2. Other featureS that differ L. bicolorangelus sp. nov. iS Ant IV not annulated and without apical bulb (preSent in L. bicolor), prelabral chaetae Smooth (ciliate in L. bicolor), unguiculi truncate (acuminate in L. bicolor), and manubrial plate with 2 blunt mac (4 in L. bicolor).
In general, the dorSal chaetotaxy and other morphological characteriSticS of L bicolorangelus sp. nov. reSemble L. colormutatus sp. nov. (See remarkS of thiS SpecieS).
