Genus Pseudosinella Schäffer.

Pseudosinella magna sp. nov.

Description: Body 2.75–3 mm. in length and more or less completely clothed with scales which increase in size progressively from the head backwards. Colour a pale cream with dark brown to purplish brown markings. Ventral surface a pale greenish-yellow. The scales are easily dislodged from the body, which then presents a creamy grey appearance. Abdomen IV three times as long as Abdomen III. A tuft of long, stout setae is situated at the apex of the mesothorax. Some of these are bent over at their tips, flattened, and ciliated on the outer flat portion. Occasional long, ciliated hairs occur at random on the trunk and appendages. Antennae four-segmented, the ratio of the segments being as 2:5:3:5: First segment of the antennae is pale ochreous in colour, the remainder dark reddish brown. The joints are very weak, especially that between the second and third segments, specimens often being found with one or both antennae broken off at this joint. Antennae densely

Legs dark brown in colour with, generally, yellow bands at the joints. The superior claws of the feet carry two rudimentary teeth on the inner margin and on the outer edge a large, slightly-curved tooth. The inferior claws about two-thirds the length of the superior, lanceolate and acuminate. Two long, slender basal wing-like processes occur on each foot. A tenent hair to each foot. Fureula reaches forward to the ventral tube. The dentes and manubrium related as 11:9 respectively. Dentes corrugated ventrally. Mucrones tridentate, the terminal tooth oblique and slightly curved, the middle large and conical, the proximal rudimentary. A small tenaculum invested with a single long curved seta is situated on the posterior margin, of the third abdominal segment.
