|scientific name Lissothrips |
Mosses (Chiasson, 1986), lichen (Mound and Walker, 1986).
Members of this genus are generally small and greenish (Thomasson and Post, 1966). The surface of the head is smooth and the eyes are mid-sized to small. Ocelli may be present or absent, and the postocular setae are well developed and vary in shape from pointed to dilated. Cheeks lack strong bristles. The antennae are 8 segmented with segment 3 smaller than either adjoining segment. Antennal segment 3 lacks or has 1 sense cone, segment 4 has 1 inner and 1 or 2 outer sense cones, and segment 8 is closely joined to segment 7 and varies from lanceolate to nonpedicellate. The maxillary stylets retract far into the head and are spaced fairly far apart when retracted. The thorax is smooth and the major setae on the prothorax are well developed. The epimeral setae are usually quite long, and the epimeral sutures are most often incomplete. The basantra is absent and the mesopraesternum is degenerate. Macropterous, brachypterous and apterous forms occur in this genus. In specimens where the fore wings are fully developed, they are not indented medially. The fore legs are unarmed. The pelta ranges from oval to nearly square and it is not divided into 3 parts. The major posterior setae on tergite 9 are often long and pointed. In males, abdominal sternite 8 may or may not have a glandular area (Stannard, 1968).
Only one species is found in Canada (Chiasson, 1986).
Feeds on mosses (Chiasson, 1986).
Most species in this genus are found in the Neotropics, as well as in Mexico, Brazil, the West Indies, Florida, Texas (Chiasson, 1986, Mound and Marullo, 1996), and North Dakota (Thomasson and Post, 1966).
