|scientific name Cryptothrips |
Under the bark of dead branches (Chiasson, 1986).
The body is black (Stannard, 1957), the head is rectangular and much longer than wide. The dorsum is mainly smooth, with a hint of hexagonal reticulations near the sides and base of the head. The eyes are small and the postocular setae range in size from small to long, but if long the setae are pointed. Ocelli are present, though reduced in brachypterous specimens. The antennae are 8 segmented, and segments 4 to 7 are produced ventrally at the apex and are only slightly elongate. The maxillary stylets touch when retracted into the head. The major setae on the prothorax are well developed though the anterior setae are smaller than the posterior setae. The epimeral sutures are complete and the basantra is present. The forelegs are armed in males but unarmed in females. Macropterous and brachypterous forms occur in this genus, and when fully developed, the wings are broad. The pelta is midsized and hexagonally reticulated, and wing-holding setae are present on the abdominal tergites in macropters (Stannard, 1968).
Feed on fungal spores (Chiasson, 1986).
Holarctic (Mound and Marullo, 1996).
