Oligoaeschna

Oligoaeschna is a genus of dragonfly in the family Aeshnidae. It contains the following species:Oligoaeschna amata (Förster, 1903) Oligoaeschna amani Chhotani, Lahiri & Mitra, 1983 Oligoaeschna aquilonaris Wilson, 2005 Oligoaeschna buehri (Förster, 1903) Oligoaeschna elacatura (Needham, 1907) Oligoaeschna foliacea Lieftinck, 1968) Oligoaeschna modiglianii Selys, 1889 Oligoaeschna mutata Lieftinck, 1940 Oligoaeschna petalura Lieftinck, 1968 Oligoaeschna platyura Lieftinck, 1940 Oligoaeschna poeciloptera (Karsch, 1889) Oligoaeschna pseudosumatrana Karube, 1997 Oligoaeschna sumatrana Lieftinck, 1953 Oligoaeschna uemurai Asahina, 1990 Oligoaeschna uropetala Lieftinck, 1968 Oligoaeschna venatrix (Förster, 1903) Oligoaeschna venusta Lieftinck, 1968 Oligoaeschna zambo Needham & Gyger, 1937

No picture of Oligoaeschna was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Oligoaeschna, or no answer at all. This entry cannot say which.

9 occurrences of Oligoaeschna on record. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

9 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

469 taxa

The Paleobiology Database records 8 sites for Oligoaeschna, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

9 references

Each of the 9 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
