Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Lethrus obsoletus Semenov, 1894 is considered as subspecies of L. tenuidens Reitter, 1890: Lethrus tenuidens obsoletus Semenov, stat. n. Distribution of all known species of the subgenus Furcilethrusis detailed. Key to species of the genus on males is given.
