Remarks.

The subfamily Larinotinae was originally established for the genera Colydiopeltis , Parapeltis and Larinotus ( Ślipiński 1992). I removed the first two genera into the separate tribe Colydiopeltini under Peltinae ( Kolibáč 2006), leaving Larinotini monotypic. Ślipiński (l.c.) remarked upon the similarity of the adult Larinotus and Necrobiopsis ( Trogossitinae : Egoliini ) but, on the other hand, he also pointed out common features of the Larinotus larva and some Peltinae ( Rentoniinae , Protopeltis in his original text). Crowson (1970) also classified Larinotus (described as Nebophilus hirsutus ) within Egoliini . All the opinions of the both these authors are in perfect agreement with my observations ( Kolibáč 2006, 2008). Finally, character analyses (l.c.) also resulted in a close relationship between Larinotini and Egoliini . The relationship of adults appears to be so close that one might speculate about the paraphyly of Larinotini ; it is, however, hard to justify such a hypothesis if one considers the monotypy of the latter (all derived features found in Larinotus are only autapomorphies).

The closed mesocoxal cavities are the single apomorphy distinguishing Larinotini from adult Egoliini . Larval characters connecting Larinotus with Peltinae are: (1) cranium with median endocarina, (2) gula with anterior apodemes, (3) strongly reduced urogomphi (minute, apices downturned). However, character states 1 and 2 are considered plesiomorphies while the third character state (reduction of urogomphi) could be a tendency observed in various cleroids living in tightly-confined surroundings (e.g. Peltis , Cleridae : Dermestoides ).
