Kirejsthuk, A. G.: On the fauna of Nitidulidae (Insecta, Coleoptera) from Taiwan with some taxonomical notes

eral subapical expansion is more raised in the specimens from the Philippines, and the outline of inner edge of lateral lobes before apex is also variable. Diagnosis - This form treated here as new species has a combination of the distinguishing characters which are used in the key below. It is the commonest member of the genus in the Palaearchearctic Province and Indo-Malayan Region, which was confused by many previous researchers with A. discolor. However, it can be easily distinguished from the latter by its more oval body with shorter elytra, more developed and more conspicuous dorsal pubescence, shape of male pygidium and hypopygidium, suboblique posterior angles of pronotum, wider median plate of the mesosternum, configuration of distal edge of the spiculum gastrale and lateral lobes of tegmen. At the same time, this new species is very similar to A. oblongus GROUVELLE, 1897 in many external characters (including shape of the pygidium and hypopygidium) and structure of genitalia. These "species" are different mostly in the presence/absence of paramedial brushes on elytra, shape of prosternai process and spiculum gastrale. This situation is similar to that in the pair of A piceus (MOTSCHULSKY, 1863) and A. japonicus REITTER, 1873. Furthermore, the specimens of the new "species" under consideration are in general somewhat larger and more robust than those of A. oblongus, frequently have more curved lateral lobes of tegmen and can be characterized by some differences also in the distribution. Finally, variation in structure of different organs of the new "species" is much wider than that in A. oblongus. Thus, the separation of these forms needs to be clarified in a further study. See also the diagnoses of A. montanus sp. n., A. nebulosus sp. n., A. opinatus sp. n. and A. triparcus sp. n. Etymology - The name of this species is devoted to ANDREY L'VOVICH LOBANOV, a friend and good colleague of the author for making new web pages and maintenance of the site "Beetles (Coleoptera) and coleopterists".
