Abstract.The present research represents the first description of a Vespidae species spermatozoon. In Agelaia vicina, the sperm head is composed of an acrosome and a nucleus. The acrosome consists of an acrosomal vesicle, oval shaped in cross sections, and a perforatorium, that projects into the anterior nuclear region. The nucleus is elongated and oval shaped in cross sections. The nucleus-flagellum transition region includes the centriolar adjunct, the nucleus base and the anterior portions… 
Morphology of spermatozoa of Dissomphalus connubialis (Ashmead, 1893) (Hymenoptera: Bethylidae).
TLDR
Spermatozoa of D. connubialis shows characteristics not seen in other Hymenoptera, such as the wide electron-lucid region that separates the acrosomal vesicle from the perforatorium and the depth of the cavity in the anterior extremity of the nucleus.
Sperm structure and ultrastructure of the Melittobia hawaiiensis, Perkins and M. australica, Girault (chalcidoidea: eulophidae).
TLDR
This is the second study describing spermatozoa morphology of an Eulophidae species in which important characteristics were observed and two mitochondrial derivatives, which in cross-sections are asymmetric, are observed.
Sperm morphology of the Prorops nasuta (Waterston, 1923) (Hymenoptera: Bethylidae).
TLDR
Spermatozoa of the Prorops nasuta (Hymenoptera: Bethylidae) parasitoid were described morphologically and have various exclusive characteristics that may be useful for studying the phylogeny and taxonomy of the superfamily Chrysidoidea and of Hymanoptera in general.
The short spermatodesm of Arge pagana (Hymenoptera: symphyta).
TLDR
The centriolar adjunct asymmetry and the occurrence of spermatodesm bundles might be considered plesiomorphic states present in the basal Tenthredinoidea.
Sperm ultrastructure of the European hornet Vespa crabro (Linnaeus, 1758) (Hymenoptera: Vespidae).
TLDR
The sperm morphology of V. crabro is very similar to that of the polistine wasp, Agelaia vicina, which can indicate that, in Vespinae, sperm morphology is maintained without important variations among subfamilies and/or that this similarity indicates close phylogenetic relationship between these two subfam families.
Morphology of testicular and post-testicular spermatozoa in Microstigmus arlei Richards, 1972 and M. nigrophthalmus Melo, 1992 (Hymenoptera: Apoidea: Pemphredoninae) with phylogenetic consideration.
The sperm of Microstigmus arlei and Microstigmus nigrophthalmus are twisted in a spiral and consist of two regions: the head, formed by an acrosome and a nucleus, and the flagellum, formed by two
Structure and ultrastructure of the spermatozoa of Trypoxylon (Trypargilum) albitarse Fabricius 1804 (Hymenoptera: Apoidea: Crabronidae).
TLDR
The characters derived from the ultrastructure of the spermatozoa of T. albitarse show synapomorphies shared with the Apoidea and present characters that are probably apomorphic for the Crabroninae subfamily.
Sperm ultrastructure of five species of the Neotropical ant genus Pseudomyrmex (Hymenoptera: Formicidae)
TLDR
New morphological characters that are specific to Pseudomyrmex, are valuable synapomorphies of the genus and can be used in taxonomic characterization of the Pseudmyrmecinae subfamily and in phylogenetic analyses in Formicidae family.
Ultrastructure of spermatozoa in two solitary bee species with an emphasis on synapomorphic traits shared in the family apidae
TLDR
The structure and ultrastructure of spermatozoa from Thygater (Thygater) analis and Melitoma segmentaria were characterized and the synapomorphies shared in the family Apidae are discussed.
Sperm Bundles in the Seminal Vesicle of the Crematogaster victima (Smith) Adult Males (Hymenoptera: Formicidae)
TLDR
The presence of sperm bundles in sexually mature males of Crematogaster victima differentiates C. victima from other ants; however, the similarities in the sperm ultrastructure support the monophyly of this insect group.

Ultrastructural characterization of spermatozoa in euglossine bees (Hymenoptera, Apidae, Apinae)
TLDR
Euglossine spermatozoa are the longest described to date for the Hymenoptera and include a head and a flagellar region and species-specific differences that might be useful in phylogenetic work on the group are noted.
Structure and ultrastructure of the spermatozoa of Halictidae (Hymenoptera, Apoidea).
TLDR
The typical pattern for Halictidae spermatozoa here described may provide useful additional information for future phylogenetic analysis of the superfamily Apoidea.
Sperm structure and ultrastructure of the fire ant Solenopsis invicta (Buren) (Hymenoptera, Formicidae).
TLDR
In relation to other aculeates, it is possible that three characteristics (type of centriolar adjunct, presence of paracrystalline areas in each mitochondrial derivative, and the position of these areas within each derivative) may be autopomorphies for the Formicidae.
Structure and ultrastructure of the spermatozoa of Bephratelloides pomorum (Fabricius) (Hymenoptera: Eurytomidae)
TLDR
These structural variations demonstrate that the sperm of chalcidoids provide characteristics that can certainly prove useful for future phylogenetic analysis at the subfamily level and, possibly, the genus too.
Sperm ultrastructure of the honey bee (Apis mellifera) (L) (Hymenoptera, Apidae) with emphasis on the nucleus-flagellum transition region.
TLDR
The structure identified here as a centriolar adjunct is homologous to that observed in Formicidae, Ichneumonoidea and Symphyta and therefore, very probably, it is common to most Hymenoptera.
Structure and ultrastructure of spermatozoa in Meliponini (stingless bees) (Hymenoptera: Apidae).
TLDR
It is concluded that it is possible to define a characteristic pattern for Meliponini spermatozoa, and species-specific differences are found that could be used in a taxonomic or phylogenetic evaluation.
Sperm ultrastructure of the bees Exomalopsis (Exomalopsis) auropilosa Spinola 1853 and Paratetrapedia (Lophopedia) sp. Michener & Moure 1957 (Hymenoptera, Apidae, Apinae).
TLDR
The structure and ultrastructure of the spermatozoa of the bee species here described are similar to the majority of sperm found in the other Hymenoptera and may be a contribution for future phylogenetic analysis of Apidae.
Comparative ultrastructure of ant spermatozoa (formicidae: Hymenoptera)
TLDR
Spermatozoa obtained from A. versicolor, a species that is known to store and utilize viable sperm from this supply for over 10 years, show greater development of the mitochondrial derivatives than do the other species.
Structure and ultrastructure of the spermatozoa of Trichogramma pretiosum Riley and Trichogramma atopovirilia Oatman and Platner (Hymenoptera: Trichogrammatidae).
TLDR
It is argued that the spiralling of the flagellar structures is a synapomorphy for Trichogrammatidae as well as for Eulophidae + Eurytomidae  + Pteromalidae.
Redescription of sperm structure and ultrastructure of Trichogramma dendrolimi (Hymenoptera: Chalcidoidea: Trichogrammatidae)
TLDR
It is now possible to affirm that the helical sperm structures are an apomorphic homology for Trichogrammatidae as well as Eulophidae, Pteromalidae, Eurytomidae, Torymidae, Mymaridae and for some other chalcidoids, if not all.
