Mystrothrips clavatoris Hood

(Figs 7–8)

Mystrothrips clavatoris Hood, 1954: 32

This species shares with some specimens of dammermanni, the type species of the genus, the presence on the head of a pair of capitate mid-dorsal setae that are equal in size to the postocular setae (Fig. 7). At present, clavatoris is distinguished from the other members of the genus by the presence of well-developed prosternal basantra (Fig. 8), four sense cones on antennal segment IV, paired slender capitate setae on antennal segments I–IV, and a series of smaller capitate setae laterally on the head (Fig. 7).

Specimens examined. Female microptera, Brazil, Santa Catarina, Nova Teutonia, from fallen leaves, vii.1955 (F. Plaumann), in BMNH.
