Etymology. The specific name is a patronym in honour of Dr. Rafael Prezzi Indicatti, an expert Brazilian arachnologist and exemplary researcher. He acted as a mentor for VMG in some of VMG's first taxonomic practises while an undergraduate in biology at UNESP, working with mygalomorph spiders. Furthermore, he always supports Projeto Phasma - a freestanding phasmid research group of which all the authors are part of. Besides insightful institutional and research advice, he is frequently skilfully collecting specimens of stick insects when possible and organizing and aiding in fieldtrips with Projeto Phasma members, as the one which resulted in the collection of the new species. This comes in form of our sincerely gratefulness for kindly helping us and supporting research on Phasmatodea   in Brazil.

Diagnosis. Ceroys (Miroceroys) indicattii   sp. nov. resembles Ceroys (Miroceroys) saevissimus   and differs from all remaining species of the genus by the conspicuous dorsolateral medial widening of the mesonotum ( Fig. 10B View FIGURE 10 , 13B View FIGURE 13 ) and overall pattern of ornamentation, such as lateral and dorsal expansions in abdominal segments and several strong spines in the thorax ( Fig. 10B View FIGURE 10 ), less prominent in males ( Fig. 13 View FIGURE 13 ). It differs from females of Ceroys (Miroceroys) saevissimus   by the shorter and less deflexed posterior margin of tergite X (anal segment) and shorter sternite VIII (subgenital plate), with both not forming a duck-bill shape ( Fig. 12B View FIGURE 12 ) as in C. saevissimus   , the larger dorsal expansions on tergites IV, V and IX ( Figs 10B View FIGURE 10 , 12B View FIGURE 12 ) and by the tergite VIII slightly wider than IX and X, not constricted ( Fig. 10A View FIGURE 10 ). Males are recognized by the straight mesonotum in lateral view, smaller, less jagged triangular thoracic projections and less spiny body with abdomen segments without lateral spines in both anterior and posterior margins ( Fig. 13 View FIGURE 13 ).
