“…The acrosome and flagellum formation occurs simultaneously with the nuclear transformations, which change in shape and in chromatin condensation degree. These events follow the general pattern described for other Coleoptera (Baccetti and Daccordi, 1988;Burrini et al. 1988).…”

“…castaneum (Dias et al, 2010) and Te. molitor (Burrini et al, 1988), for having an asymmetrical vesicle base through a dilatation on one side. In addition, the flattened form of the acrosome is another characteristic that differentiates spermatozoa of L. villosa from that of Tr.…”

“…Thus, ultrastructural variations of these cells have been used to resolve phylogenetic relationships of various groups, including beetles (Baccetti and Daccordi, 1988;Burrini et al, 1988;Jamieson et al, 1999). Tenebrionids, curculionoids and chrysomelids are among the major groups that make up the Cucujiformia infraorder.…”

“…Tenebrionids, curculionoids and chrysomelids are among the major groups that make up the Cucujiformia infraorder. Spermatazoa morphology of various Curculionoidea (Burrini et al, 1988) and Chrysomelidae (Baccetti and Daccordi, 1988) species was described over twenty years ago. However, for tenebrionids, there are few studies of spermatozoa structure.…”

The systematics of tenebrionids remain unclear, principally at the subfamily level, as is the case of the Lagriinae. Considering that sperm morphology has contributed to the various insect group phylogenies, in this work we describe the structure and ultrastructure of these cells in Lagria villosa. Sperm in this species exhibit a strong morphological similarity to those of Tenebrio molitor and Tribolium castaneum, the only two species of Tenebrionidae with previously described sperm. In tenebrionids, the flagellar components offer good diagnostic characters, e.g. the symmetry of mitochondrial derivatives in L. villosa differentiates sperm of this species from those of Te. molitor and Tr. castaneum. However, the lateral association of the nucleus with flagellar components, the form of accessory bodies, and the presence of material connecting the axoneme to the accessory bodies and mitochondrial derivatives indicate that the three species form a sister group. Therefore, the sperm morphology of L. villosa support lagriid beetles as a subfamily (Lagriinae) of Tenebrionidae.

The sperm morphology can provide helpful information about sexual selection, phylogeny, and the evolutionary history of a given animal group. However, there is limited or no knowledge of many taxa, especially those belonging to insects, a vast and highly diverse group. An example is the Miridae, or plant bugs, which belong to the infraorder Cimicomorpha (Heteroptera), where only three out of 17 families have published data on their sperm morphology. Here we described the Miridae sperm structure by analyzing Pycnoderes incurvus sperm under light and transmission electron microscopy. In this species, the spermatozoa were as long and slender as those of most insects. However, the anterior‐most region was twisted, a characteristic first reported for Heteroptera. The acrosome was coated with electron‐dense material, most likely extra‐acrosomal. The centriole adjunct was a notably long, cylindrical and compact structure connecting the nucleus to the flagellar elements, with just clove‐like electron‐lucent points in cross‐section, also features unique to Miridae so far. The flagella exhibited an axoneme of 9 + 9 + 2 microtubules and two symmetrical mitochondrial derivatives. The latter two partially embrace the axoneme, and each exhibits two paracrystalline areas and a bridge connecting it to the axoneme; these are considered Heteroptera synapomorphies that support their monophyly.Research Highlights The P. incurvus sperm showed a twisted acrosome, the first reported for Heteroptera. The centriolar adjunct is a sole structure linking the nucleus and flagellum. The flagella presented the synapomorphies supporting Heteroptera monophyly.
