Stereostoma Murray 1857
Recognition-
Large deep-bodied species with
prominent eyes that lack the prominent temples found in other morionine
taxa.
Distribution/Diversity-
Stereostoma (s.str.) contains
six
species
from western Africa. The
22 species of Stereostoma
(Stereodema) are known
from western and west-central Africa.
Taxonomy/Systematics-
Stereostoma s.lat. lacks many
of the characteristics presumed to be
derived for typical morionines. The most obvious morionine features of
the head, e.g., the prominent temples and emargination of the labrum
and clypeus, are not observed in Stereostoma.
Several autapomorphies
distinguish Stereostoma,
including the complete enclosure of the apex
of tarsomere 5, apical margin of
the labrum with only 4
setae in some species (6 in all other Morionini), and
supernumary setae of the pronotal margin (found in some Morion and
Moriosomus species). Stereostoma (s.str.) species lack
the maxillary
and antennal characteristic of Stereostoma
(Stereodema) Chaudoir and are most likely paraphyletic
relative
to Stereodema. No
identification key is available for these species. Stereostoma (Stereodema) species
(except S. praecellens
Müller) are separable using Straneo's (1991)
key to species.
Biological information- Species
may be assocciated with termites.
