About 2,000 specimens of Psocoptera were collected in Malta recently. Examination of this material revealed 21 new records for the Maltese archipelago, augmenting the known psocid fauna of these islands from 6 to 27 species. One of the most abundant species is Peripsocus stagnivagus Chapman, 1930 (= P. bivari Baz, 1988 = P. leleupi Badonnel, 1976, new synonymies), formerly considered to be a predominantly Nearctic species. The discovery in Malta, of one male of this usually parthenogenetic species enabled comparison of this first Palaearctic male with the well-documented, rare Nearctic male. The lack of any morphological difference between these males, or between females from the Nearctic, the western Palaearctic and several Atlantic islands, supports the proposed synonymies.
最近在马耳他采集了约2000份啮目昆虫标本。对这些标本的检查发现了21种马耳他群岛新记录，使这些岛屿已知的啮目昆虫种类从6种增加到27种。最常见的物种之一是1930年的静水围啮（Peripsocus stagnivagus Chapman）（= 1988年的双变围啮（P. bivari Baz） = 1976年的勒氏围啮（P. leleupi Badonnel），新异名），以前被认为主要是近北极地区的物种。在马耳他发现的这一通常孤雌生殖物种的一只雄性，使得能够将这只首个古北界雄性与记录完备的罕见近北极界雄性进行比较。这些雄性之间，以及近北极界、古北界西部和几个大西洋岛屿的雌性之间没有任何形态差异，这支持了所提出的异名关系。
