Remarks. Lepidocyrtoides colormutatus  sp. nov. reSembleS L. bicolorangelus  sp. nov. by body heavily pigmented of dark blue, dorSal head with 1 median and 1 Sutural mac and Pp5 mac preSent; Th II with 4 poSterior mac; Th III –Abd III with 0, 1(lateral), 3 and 1 median mac, reSpectively, and manubrial plate with 2 blunt mac. However, L. colormutatus  sp. nov. differS from thiS SpecieS by baSomedian labial field with M2 chaeta (abSent in L. bicolorangelus  sp. nov.), 4 anterior poStlabial Spine-like chaeta (3 in L. bicolorangelus  sp. nov.), trochanteral organ with about 98 Spine-like chaetae (48 in L. bicolorangelus  sp. nov.), unguiculuS III acuminate (truncate in L. bicolorangelus  sp. nov.) and dorSal denS with rowS of unilaterally ciliate chaetae, while in L. bicolorangelus  sp. nov. there iS 1 proximal blunt ciliate chaetae and the unilaterally ciliate chaetae are abSent. DorSal chaetotaxy of L. colormutatus  sp. nov. Still differS by Th II with 18–21 anterior mac, and Abd IV with 16–20 median mac, white L. bicolorangelus  sp. nov. haS 9–21 anterior mac on Th II and 12–16 median mac on Abd IV.
