Sisyra is a of spongillaflies (Neuroptera: Sisyridae), a small of aquatic insects. The genus comprises at least eight described distributed across multiple continents, including Brazil, Panama, Australia, and Asia. Sisyra species have been documented in freshwater , with larvae associated with freshwater sponges. The family holds a basal phylogenetic position within Neuroptera, and at least one species (S. nigra) exhibits an unusual achiasmatic segregation mechanism not observed in other neuropterans.

More Details
Cytogenetic significance
Sisyra nigra exhibits a unique achiasmatic segregation mechanism ('touch-and-go pairing') during male , differing from the syntelic orientation and distance pairing typical of other Neuroptera. This finding supports the basal phylogenetic position of Sisyridae within the order.
Taxonomic changes
Sisyra ariasi Penny, 1981 has been synonymized with S. panama Parfin and Gurney, 1956 based on Brazilian distributional and taxonomic studies.
Parasitoid relationships
The is to specialized ; Trichomalopsis sisyrae (Hymenoptera: Pteromalidae) is documented as a parasitoid of Sisyra in Tasmania, Australia.
Genomic resources
Mitochondrial have been sequenced for S. aurorae (first Asian mitogenome) and nuclear genome for S. nigra.
