Synopsyllus estradei is a species of Siphonaptera from Pulicidae family, identified for the first time in Madagascar by professor J. M. Klein in 1964. The prepared slide is from MNHN, Paris collection.

This species was collected in a nest identified probably as a nest of Eliurus (rodent in the family of Nesomyidae).

 

At the time of discovery of this new species, it was the third species of Synopsyllus known :

  1. Synopsyllus fonquerniei (on Ratus ratus)
  2. Synopsyllus smiti (on Macrotarsomys ingens)
  3. Synopsyllus estradei (probable on Eliurus sp.)
  4. Synopsyllus robici (discovered after S. estradei)
  5. Synopsyllus girardi (discovered after S. estradei)

Publication of the description of the species available on the net :

UNE NOUVELLE ESPECE DE SYNOPSYLLUS (INSECTA, SIPHONAPTERA) DE LA FORET ORIENTALE DE MADAGASCAR, S. estradei par J. M. KLEIN (Bulletin de la Société de Pathologie exotique. Extrait du tome 57, no I, Janvier-Février 1964)

The genus Synopsyllus has been first described by Wagner and Roubaud, in 1932. It is characterised by :

  • Metasternum and metepisternum fully fused without vestigial suture (this is also the case for Synosternus Jordan, 1925),
  • Anterior occipital seta (not present in Synosternus),
  • Spermatheca has much bigger size than the one of Synosternus.

The spermatheca of Synopsyllus estradei is anyway quite different from the other species of Synopsyllus.

The new species was dedicated to Mr. Dr. F. ESTRADE Chief Director of Hygiene and Prevention  (SGHMP) and Director of the Institute of Social Hygiene of the Malagasy Republic.

You have on the following link a comparison with related genera Synosternus. I promise I will explain more in details in future, what means exactly fusion of metasternum and metepisternum, which could sound really esoteric for most of people !

I hope you will apppreciate the beauty of these photos ?
