ABSTRACT Tenebrionid beetles have been highly successful in colonising environments where water is scarce, underpinned by their unique osmoregulatory adaptations. These include a cryptonephridial arrangement of organs, which part renal/Malpighian tubules are bound to the surface rectum. Within tubules, an unusual cell type, leptophragmata, plays key physiological role underpinning conservation. Nothing was known about developmental mechanisms or evolution these renal cells. Here, we investigate leptophragmata development Tribolium castaneum. We find that express and require Tiptop transcription factor, similar secondary cells Drosophila melanogaster, Teashirt Tiptop, despite lacking crypronephridial arrangement. An additional Dachshund, required establish identity distinguish them from non-cryptonephridial region tubule Tribolium. Dachshund also expressed sub-population Drosophila. Leptophragmata, beetle lineage, appear originated specific type present ancestrally be specified conserved repertoire factors.

ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in organs gut been dramatically reorganised. Parts of or Malpighian tubules (MpTs) form a close association with surface rectum, are surrounded by novel tissue, perinephric membrane, acts insulate system from haemolymph thus allows tight regulation ions water into out CNC. CNC can reclaim solutes rectal contents recycle these back haemolymph. Fluid flow MpTs runs counter within rectum. It this countercurrent arrangement that underpins its powerful recycling capabilities, represents one most efficient conservation mechanisms nature. CNCs appear evolved multiple times, present some largest evolutionarily successful insect groups including larvae Lepidoptera major beetle lineage (Cucujiformia + Bostrichoidea), suggesting important adaptation. Here we review knowledge remarkable organ gained over past 200 years. We first focus on tenebrionid beetles, in‐depth understanding physiological, structural ultrastructural studies (primarily Tenebrio molitor ), now being extended Tribolium castaneum enabled advances molecular microscopy approaches established species. These recent beginning illuminate development, physiology endocrine control. then take broader view arthropod CNCs, phylogenetically mapping their reported occurrence assess distribution likely origins. explore ecological viewpoint, put forward evidence may primarily be adaptations facing challenges larval life, argue loss many aquatic species could point primary conserving terrestrial Finally, considering functions epithelia insects lacking as well typical architecture relation another, propose ancestral features predispose them evolution CNCs.
