“ Odynerus” hyalinelamellatus Giordani Soika, 1941

( Figs 2K ; 60B ; 61E, F ; 66K )

Odynerus hyalinelamellatus Giordani Soika, 1941: 174 , ♀ —“ Bekily ” ( type lost).

Distribution. Madagascar: Antsiranana *, Toliara ( Giordani Soika 1941) ( Fig. 66K ).

Notes. The specimen from Antsiranana, Sakalava Beach ( CASENT2081256 ), has the apical lamellae of T2 – T3 clearly less developed ( Fig. 61F ) than the specimens from Toliara ( Fig. 61E ), but otherwise does not show any difference. Given the homogeneity of the females in this group of species and the provenance from opposite ends of the island, it cannot be excluded that it is a similar but distinct species, however the question cannot be clarified in the absence of male specimens. For the moment the specimen from Antsiranana is identified as Odynerus hyalinelamellatus due to the presence of the lamella also on T3 . Given the apparent taxonomic complexity of this group, it would be desirable to designate a neotype as a reference standard for this species but given the homogeneity of females I prefer to defer this taxonomic action to when male specimens or genetic data will be available, so that a more representative neotype can be designated .
