Remarks. Lepidocyrtoides caeruleomaculatus   sp. nov. reSembleS Lepidocyrtoides villasboasi   comb. nov. ( Arlé & GuimarãeS, 1981) by body with blue SpotS and bandS, Ant IV annulated and without apical bulb, reduced dorSal chaetotaxy of head and Th III, Abd II–III with 3 and 1 median mac reSpectively; ungueS with apical tooth, unguiculuS I truncate and II–III acuminate, and dorSal denS with proximal rowS of unilaterally ciliate chaetae. However, L. caeruleomaculatus   sp. nov. differS from thiS SpecieS by diStinct color pattern with Scattered SpotS, while L. villasboasi   comb. nov. haS tranSverSe bandS of dark blue on Th III–Abd III and Abd IV poSteriorly ( FigS 1A, H View FIGURE 1 ). The chaetotaxy of L. caeruleomaculatus   sp. nov. differS by abSence of Pp5 mac on head (preSent in L. villasboasi   comb. nov.), baSomedian labial field with chaetae e, l1–2 Smooth and R preSent (E, L1–2 ciliate and R abSent in L. villasboasi   comb. nov.), and ventral head devoid of Spine-like mic on anterior poStlabial region (preSent in L. villasboasi   comb. nov.). Th II differS by 14–15 anterior mac and 1 poSterior meS (22–24 anterior and 5 poSterior mac in L. villasboasi   comb. nov.), Abd I without mac (1 in L. villasboasi   comb. nov.), and Abd IV with 13 median mac (16–20 in L. villasboasi   comb. nov.). Other differenceS of L. caeruleomaculatus   sp. nov. are trochanteral organ with about 107 Spine-like chaetae (48 in L. villasboasi   comb. nov.); and manubrial plate with 4 blunt mac (2 in L. villasboasi   comb. nov.).
