Berberentulus durumagi s p. n. (Figs. 1-5) This new species is similar to Australian species, such as B. validus and B. aestuarii, in its short foretarsal sensilla b, in the presence of b' on its foretarsus, as well as in the presence of accessorry setae P la on abdominal terga I—VII. The two Australian forms differ from the new Korean species in the absence of posterior setae on abdominal sternite VIII. They lack anterior setae A 4 on tergite VI and differ in the size of foretarsal sensilla e as well. Body length 710-720 fj, in two unexpanded adults. Mouthparts small. Maxillary palpus rather clumsy. Sensillae on maxillary palpus stout, that on labial palpus short and broad. Pseudoculus almost circular, PR= 15—16. The "filamento di sostegno" of the maxilla simple and its proximal part relatively short. Foretarsus (Figs. 1-2) 89-94 p. in length, TR = 3.7-3.9. Empodium short, EU = 0.11. Dorsal sensilla t-l baculiform, slightly distal to a 3 and BS=0.5-0.6; t-2 thin and long; Í-3 short. Exterior sensiha a relatively short; b and cin the same row; b shorter than c, its apex slightly surpassing base of y 2 ; d slightly distal to c and subequal to c in length ; e nearer to / than to d and apex not surpassing base of i-3 ; / thin; apices of / and g not surpassing tarsus. Interior sensilla a' broad and ensiform ; b' thin and long, its apex reaching base of c ; c also thin and long, its apex fairly surpassing base of S 6. Thoracic chaetotaxy similar to that of other BerberenUdus-iorms, but ventral M 2 on thorax I present as in Acerentulus-si>ecies ; e.g. A. kisonis. Dorsal P 5a on thorax II-III rudimentary. Tergal accessory setae P la and 2a on abdominal tergite I and P la, 2a and 4a on terga II-VI short and less than 1/5 of PI, but P la, 2a, 3a and 4a on tergite VII relatively long and more than 1/3 as long as P 1. On terga I-V three pairs of anterior setae (A 1, 2 and 5), on tergite VI four pairs {A 1,2, 4 and 5) present. Tergite VII with three pairs of anterior setae; A 2, 4 and 5. Middle setae on tergite VIII consisting of eight, as in B. morikawai and its allies. Fig. 5. Berberentulus durmagi sp. n.
