The larva of this species was described by Zhou (2007) in detail. In this study we present only the characteristic photos for diagnostic purposes ( Figs. 9–11 , 15 ). Diagnosis. The cephalic color patterns of H. simulata is very similar to those of H. yaeyamensis ( Kawai & Tanida 2005 ) , but H . simulata can be distinguished from the latter in that (1) the yellow stripe along the anterior margin of the frontoclypeal apotome is about as long as the anterior margin in H . simulata , but it is shorter and more concave than the anterior margin in H. yaeyamensis ; (2) the three triangular yellow marks in the middle of the frontoclypeal apotome are close to each other in H . simulata , but they are separated from each other widely in H. yaeyamensis ; (3) the median indentation of the submentum in H. simulata is deeper and wider than in H. yaeyamensis ; and (4) the posterior prosternal sclerites are sub-triangular in H . simulata , but they are subrectangular in H . yaeyamensis .
