Abstract:Desert tenebrionid larvae of the Tentyriini have a similar cylinder body shape making them difficult to distinguish from each other morphologically. Previous taxonomic research on desert tenebrionid larvae mainly focused on features of the setae and spinules on larval maxilla and legs and descriptions of the pigmentation pattern of larval cephalic capsule are rare. Here, We describe different pigmentation patterns on the larval cephalic capsule and compare the area of pigmentation in the three tenebrionid species; Microdera punctipennis Kaszab, Anatolica polita borealis Kaszab and Colposcelis microderoides microderoides Reitter. In addition, the ratio of the width of the larval cephalic capsule to that of  the pronotum differs among larvae of these species. This provides a convenient method to distinguish between larvae of these beetles at the third instar or above.
