The short spermatodesm of Arge pagana (Hymenoptera: symphyta)

open access: yesTissue and Cell, 2008
In the seminal vesicle of the 'symphyta'Arge pagana the spermatozoa are stored in motile spermatodesm bundles, maintained by an anterior cap of extracellular material. This cap consists of a denser cortex and of an internal matrix, where part of the sperm heads are embedded. The number of spermatozoa per bundle is variable.

The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation

open access: yesBiological Reviews, Volume 100, Issue 2, Page 647-671, April 2025.
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close

Phylogenomics and biogeography of sawflies and woodwasps (Hymenoptera, Symphyta) [PDF]

open access: yesMolecular Phylogenetics and Evolution
Phylogenomic approaches have recently helped elucidate various insect relationships, but large-scale comprehensive analyses on relationships within sawflies and woodwasps are still lacking. Here, we infer the relationships and long-term biogeographic history of these hymenopteran groups using a large dataset of 354 UCE loci collected from 385 species ...
