Etymology. ReferS to the color change (from Latin: color and mutatus ––in change) in the StageS of development of the immature to adult of the new SpecieS ( FigS 1B –D View FIGURE 1 ).

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.
