is it not Exoprosopa (Cladodisca) rivularis? Was the species migrated from Exoprosopa to Heteralonia?

I saw in a book that:
Heteralonia Rondani, 1863
(Zygodipla Bezzi, 1924)

This Rondani is not strange for me... where I heard about this author??

--- but we also can see that

(undefined subgenus!)
E ? ? P ? ? ? dispar (Loew, 1869)
E ? ? P a ? ? rivularis (Meigen, 1820) (11)
= argyrocephala (Macquart, 1840)


That fits " ARGYROCEPHALA" means silver head (cephalothorax) meaning that gena is white and with silvery, so I think that Exoprosopa rivularis was changed to Heteralonia rivularis..

According Seguy's key "FAUNE DE FRANCE 13 DIPT?RES (BRACHYC?RES) (STRAT/OMYIJDAE. ER/NN/DAE. COENOMYIIDAE. RHAG/ON/DAE. TABAN/DAE. COD/DA?. NEMESTR/N/DAE. MYDA/DAE. BOMBYLIIDAE. THEREV/DAE, OMPHRALIDAE)"

in page 187:

Exoprosopa (Cladodisca) rivu!aris MEIGE:\'.- KERT?SZ, V, 20. E. argyrocelthala
MACQUART, 181,.0: If, 1,40, 1. - Fig. 478.
Face et front couverts d'?cailles jaun?tres, bord post?rieur des yeux ?
?cailles jaunes. Antennes et trompe noires. Thorax noir: quatre bandes
plus p?les parIois peu visibles sous la longue pilosit? jaune, une tache
d'?cailles blanches ? la'base des ailes. Scutellum brun. Pattes d'un brun
noir. Balanciers jaun?tres. Ailes ? bordure costale brune; nervures bord?es
de brun noir sur disque; apex largement hyalin ou vitreux. Abdomen :
tergites avec des bandes ant?rieures d'?cailles blanches, m?lang?es
d'?cailles brunes ou dor?es au bord apical. - L: 11-16 mm.

description fits very well on this specimen. :)

and really wing venation fits 100%. :)

That?s why I'm asking: Does Exoprosopa rivularis changed to Heteralonia rivularis? :)
