A taxonomic group or classification of organisms that are disconnected or separate in nature.
Likely a Latin scientific plural form combining dis- (separated) + conectae (connected things), used in biological or zoological nomenclature to describe organisms lacking typical connections.
This appears to be a specialized scientific term that may have been used in historical taxonomy—a reminder that scientific naming evolves as our understanding improves, and many technical terms from older classification systems are now obsolete.
