scription]; Bernhauer and Scheerpeltz, 1926:713 [catalog listing, as a

Afrotropical Region — Congo, Kenya, South Africa, Tanzania, Zaire; Australian Region — New Caledonia; Nearctic Region — Mexico, U.S.A. (Arizona, California, Florida, Idaho, Indiana, Iowa, Montana, Nevada, New York, Pennsylvania, Tennessee, Texas), Neotropical Region — Argentina (Tucumán), Brazil (Rio de Janeiro, São Paulo), Colombia, Guatemala, Paraguay; Oriental Region — China [People’s Republic], India (Himachal Pradesh, Uttar Pradesh), Nepal, Singapore, Sri Lanka, Thailand; Palaearctic Region — France, Germany, Italy, Netherlands. Comments. Tinotus   clearly should be placed as a member of the tribe Aleocharini   based on a phylogenetic analysis of generic­level taxa of the Hoplandriini   (Hanley, in prep.). Based on this analysis, Tinotus   shares the following characters with members of Aleochara   , and probably represent synapomorphies for the Aleocharini   :

1. Hairs of the prostheca of the mandibles arranged in numerous rows, appearing more­or­less bushy.

2. Ligula of the prementum short, length to width ratio less than 2.5.

3. Apex of the ligula somewhat bifid to crescent­shaped.

4. Setae at extreme apex of ligula long, about 0.3 to 0.5 times length of ligula.

5. Medial spines on the ligula absent, twin asetose pores present.

6. Area of greatest width of the hypoglossal lobes at the middle of each lobe.

7. Distinct carina present, extending from base but not reaching apex of process, on the mesosternum.

Though the limits of the Aleocharini   are still uncertain, it now seems clear that Tinotus   is closely related to Aleochara   . It shares numerous uniquely derived characters with known members of the Aleocharini   , especially Aleochara   . Indeed, Tinotus   differs from other members of the Aleocharini   solely in tarsal formula. This feature is strictly autapomorphic, and is an insufficient criterion for including Tinotus   within the Hoplandriini   . This examination supports Lohse’s (1974) and Maus et al. (In press) hypotheses that Tinotus   should be included in the Aleocharini   .
