Genus Corynephoria Absolon, 1907.
Generally with swellings or prominences on dorsal surface of body. Empodial appendage represented as an accessory fine clavate seta.
This remarkable genus is represented in New Zealand by one endemic species.
Corynephoria gibbera sp. nov. Plate 72, figs. 521–523.
Colour: Entirely yellow with ocelli on black fields, and irregular dark brown or black markings.
Clothing: Sparsely clothed with short plain setae except posteriorly on Abds. V and VI, where there are numerous long stout setae.
Body: Length 0.6 mm. Antennae about half as long again as head. Ant. IV subdivided into nine sections. Ocelli, eight to each side, the central or inner ocellus very small. Abdomen posteriorly and dorsally with a large dome-like swelling or hump which is supplied with gently-curved setae. A smaller hump dorsally on thorax also.
Legs: Claw with a strong inner tooth at two-thirds, no outer teeth. Empodial appendage represented by a very fine seta not reaching to tooth of claw. I cannot be certain whether this seta is clavate but if so the clavate end is exceedingly minute. This seta also is protected by a very long heavily clavate tenent hair which is longer than the claw. There are as well three normally placed heavily clavate but distinctly shorter tenent hairs to each foot.
Furcula: Dens three times as long as mucro. Mucro long and tapering, upturned slightly at tip, granular and with a broad granulate inner lamella. Dens apically with a prominent ventral seta.
Locality: Newbury, Palmerston North, in soil by a stream. From a collection kindly sent to me by Mr. D. K. Ross.
