It has no meaning, because there's no such word known to exist. But it resembles a Latin adverb. And the Latin word 'sempiternum' means for ever in English. The form as an adjective is 'sempiternus', which means 'continual' or 'everlasting'. Both the adverb and the adjective in Latin derive from the combination of the adverb 'semper', which means 'always'; and the adjective 'aeternus', which means 'eternal' or 'everlasting'.
Sympetrum navasi was created in 1921.
Sympetrum vicinum was created in 1861.
Sympetrum meridionale was created in 1841.
Sympetrum sanguineum is the scientific name for a European dragonfly commonly called Ruddy Darter. Sympetrum is the genus name for the group of dragonflies called darters in Europe, and meadowhawks in North America. The darters are placed in the family Libellulidae; common skimmers or perchers. The word sanguineum comes from the Latin word for blood (sanguinis, sanguis), and refers to the bright red colour of the male. The female is lighter, golden-yellow.
The Band-winged Meadowhawk is the common name of Sympetrum semicinctum.Specifically, the insect is native to southern Canada and the northern United States of America. This particular dragonfly favors shallow, weedy ponds for mating, egg-laying and egg-hatching into nymphs. The female blends with the environment's general yellow-green vegetation whereas the male is obvious in bright orange, orange-red colors.
A red veined darter is a species of dragonfly with a southerly distribution in Europe but strong vagrant tendencies. It is currently designated as Sympetrum Fonscolombii but there is strong debate over whether it is really a darter so this may change. http://www.dragonflysoc.org.UK/syfon.HTML
