Pheidologitonetes adesi PACE, 1998 , comb. nov.

Zyras (Zyrastilbus) adesi PACE, 1998: 978 .

Type material examined: Paratypes: 7 exs. [all on one pin]: “ Hong Kong, Tai Po , VII.1996, G. de Rougemont / Zyras adesi det. R. Pace 96” (cAss) .

Additional material examined: Hong Kong: 5 exs., Hong Kong, X–XII.1996, leg. de Rougemont (cAss).

Comment: In the original description, which is based on 416 specimens collected in three localities in Hong Kong, PACE (1998) attributed this species to Zyrastilbus , at that time a subgenus of Zyras STEPHENS, 1835 . An examination of the above types and non-type material confirmed my suspicion that this species clearly does not belong to Zyrastilbus , from which it is not only distinguished by numerous external characters (habitus; morphology of the antennae; punctation pattern of the abdomen), but also by the different morphology at least of the female genitalia (male of the type species of Zyrastilbus unknown). Instead, it is tentatively attributed to Pheidologitonetes , with which it shares a similar habitus and antennal morphology, the presence of nonsetiferous punctation on the abdominal tergite VII, and a similar general morphology of the genitalia. On the other hand, it differs from P. setifer by rather different punctation of the pronotum ( P. setifer : with normal fine punctation and glossy interstices; pronotal midline with fine furrow), by the presence of non-setiferous punctation also on tergite VIII (absent in P. setifer ), by the shape of the posterior margin of tergite VIII (convex and not dentate in P. setifer ), and by differences in the primary sexual characters.

Pheidologitonetes adesi is undoubtedly closely allied to P. bursata ; for distinguishing characters see the following section.
