|scientific name Lissothrips muscorum |
Sphagnum and moss litter (Chiasson 1986).
Body varies around 1.1 to 1.5mm in length and is mainly dark brown. The pedicel of antennal segment 3 and the legs vary between a lighter brown and a yellowish brown. The head is smooth, and somewhat wider than long. The compound eyes are relatively small, though somewhat larger in macropterous specimens. Ocelli are absent in apterous specimens, and present in macropterous specimens. The postocular setae are long and dilated. Antennal segment 3 is small and lacks sense cones, segment 4 has 1 inner and 1 outer sense cone, and segment 8 is broadly attached to segment 7 though it narrows at the base. In macropterous specimens antennal segment 3 also has 1 outer sense cone. The mouth cone is pointed and most of the major setae on the prothorax are long and dilated. The epimeral setae are pointed. The epimeral sutures vary from almost complete to incomplete. Females are apterous or macropterous, and males are apterous. Macropterous specimens have light gray forewings that lack accessory cilia. The pelta is broadly oval, and there is no distinct glandular area on abdominal sternite 8 on males (Stannard 1968).
Feeds on mosses (Chiasson 1986).
