The larval description of <i>Tinea steueri</i> Petersen, 1966 and <i>Tinea svenssoni</i> Opheim, 1965 (Lepidoptera, Tineidae)
Fourteen larvae of Tinea steueri and six larvae of T. svenssoni were first forced out of their cases and then boiled for five minutes in 10 % potassium hydroxide. The body was opened from the right side and the inside was cleaned out. Heads were cut off and placed in 10 % potassium hydroxide for three days. After opening, the skins were kept in 70 %, 94 % and absolute alcohol for five minutes each before spreading open on a microscope slide. Euparal was used as the mountant medium. Figures were drawn direct from a microscope with possible fold showing. Not all setae could be seen on every sample, but all details have been checked on more than one larva. In Tinea svenssoni and T. steueri the distance between SD1 and XD2 is shorter than between XD1 and XD2. The clearest difference between T. svenssoni and T. steueri is the length of the cranial seta L1. In T. svenssoni L1 is as long as P2. In T. steueri L1 is the longest seta of the cranium being more than six times longer than P2. But many other differences were also found.
