Genus Odontella Schaeffer, 1897.

Ocelli five to each side; post antennal organ present. Empodial appendage absent. Furcula generally with two-lobed lamella. Cuticle strongly tuberculate. Small, usually plump insects of a dark colour.

Two species occur in New Zealand, in both of which the furcula is more or less reduced, but which I think at the present stage are best left in this genus rather than erect a new genus for their reception.

Body: Length 0·85 mm. Antennae four-segmented 5/7 as long as head. Segments III and IV indistinctly separated. Ant. I: II: III+IV as 5: 6: 11. Post antennal organ alongside ocellar field in circular enclosure and with five lobes. Ocelli five on each side on dark-brown fields. Ant. IV with small apical sense knob, 4–7 short curved sense rods, and numerous very long plain setae. Anal spines on papillae, spines plus papillae half as long as claw. Cuticle very finely tuberculate and granulate.

Legs: Claw with very minute inner tooth at three-quarters from base. No outer teeth. Two long clavate tenent hairs much longer than claw to each foot. Empodial appendage entirely wanting.

Odontella minutissima sp. nov. Plate 43, figs. 66–68.

Colour: A light creamy brown ground colour irregularly mottled with dark violet, which is heaviest in the anterior region of the body. From Abd. III posteriorly, the pigment dorsally is light and scattered.

Clothing: No setae dorsally except on Abd. V and Abd. VI, sparsely clothed laterally and posteriorly with short, plain setae. Cuticle very strongly tuberculate.

Body: Length 0·45 mm. Ocelli on black fields. Five large equal ocelli to each side. Post-antennal organ in pit alongside of ocellar field; difficult to make out but apparently with central boss and three lobes or possibly four. Ant. IV apically with several long setae and exertile sense organ. Abd. VI with two small sharply pointed spines without papillae but with their bases almost touching.

Legs: Claws long and tapering, without teeth. Empodial appendage and tenent hairs absent.

Furcula: Very much reduced, mucrodens tapering apparently to point.

Locality: Lewis Pass Saddle, 3100 ft., in leaf debris in forest.
