Thynninae 2301H

Workbook


Wasp collected 19th Jan, 2023 as an example of a species that seemed abundant that season.

5 Feb 2024: imaged metasoma and terminalia

14-15 Mar 2024: roughly cut away terminal segments of the metasoma. Imaged ‘whole’ insect only after this initial dissection (oops!).


Dissection of genitalia

Treated gaster apex, once isolated, in NaOH before further dissection. Note the I damaged the 6-7 junction during initial separation,

ventral view of gaster apex, after soaking in NaOH


Epipygium (T7)

Of particular note:

  • broad lateral lobes

  • apical depression


Hypopygium (S8)

Of particular note:

  • long apical spine (note that the upturned shape is an artefact of handing during dissection and imaging – it is suprisingly ‘bendable’)

  • short lateral spines/lobes

  • apical platform gently concave


Phallus

Paramere & part of basiparamere roughly removed on left side.

Of particular note:

  • long medial extension of BP where fused dorsally

  • very short ventral fusion of BP

  • blunt apex of parameres

  • indistinct BP-P suture
