Remarks. The body color pattern on coxae and Abd IV with lateral spots present in T. pseudomaculata sp. nov. superficially resembles T. laterolineata Soto-Adames, 2015 from Chiapas, México, but the new species differ by lateral spots on Th II to Abd II, and Abd IV laterally with 2 spots almost together, while in T. laterolineata is on coxae and collophore, and Abd IV laterally with 1 oval spot (see Soto-Adames, 2015: 10). Trogolaphysa pseudomaculata sp. nov. also differs from this species by head M4 and S5 mac present and A3 and Pm3 absent (opposite in T. laterolineata ), labral papillae with 2 separate conical projections (sharing a Y-shaped basis in T. laterolineata ), basomedian labial field devoid of extra chaeta (M3 present in T. laterolineata ), Th II with 3 mac in p3 complex (6 in T. laterolineata ), and dens outer row with 20–34 mac-like spines (9 in T. laterolineata ). The general morphology of T. pseudomaculata sp. nov. is more similar to T. nigrocephala sp. nov. and T. nigrolineata sp. nov. Therefore, for comparisons among these species see the remarks of T. nigrocephala sp. nov. and Table 2 View TABLE .
