characters. Macrocephaly [46] absent, macrothoracy [47] absent. Sternum VII without spines [48] or row of modified setae [49]. The apical edge of sternite VIII [50] shows sexual dimorphism, but bears no tubercles. - Male terminalia. Sternum IX [51] present, with setae [52] on apex. - Male genitalia. Aedeagus median lobe [53] bulb-like, internal sclerites [54] present, symmetrical/paired. Apical opening [55] well developed, modified into clasping structure. Median face membranous [56], without apicomedial hook [57]. Paramercs [58] not wrapping, without extra lobe [59] or membranous region [60], without setae [61]. Without visible pump and flagellum [62]. - Female terminalia. Female genital appendages [63] are divided into coxites, valvifers and styli. Sclerites (possible remnant of Sternum X) [64] appear as small ring. - Female genitalia. Spermatheca [65] sclerotized. Receptacle [66) divided, not associated with invisible [67] spermathecal gland, tubular portion [68] not penetrating distal bulb, umbilicus [69] absent. Sclerotized "tube" [70] cannot be found. Diversity and distribution - Mimopaederus is an enigmatic taxon appearing to be exclusively South Pacific; in fact only known from 2 species occurring on Rapa Island -also called Rapa Iti to distinguish it from Rapa Nui (Easter Island). Rapa is the remnant of a collapsed volcano, its submerged crater forming the island's harbour. The age of the island is estimated 4.13-5.02 Myo (MUNSCHY etal. 1998). Its area is 40 km 2 , latitude 27°36', no coral reefs surrounding. The highest peak on the island is Mt. Perahu (650m). Specimens of Mimopaederus were most often collected associated with leaves; either beaten from bushes or extracted from leaf litter. One of the species occurs in lower altitudes, the other is found exclusively around the peak of Mt. Perahu at an altitude of 550-630 m. This genus is supposed to be closely related to Thinodromus, it may actually be derived from an ancestor of that genus. Apart from the fully developed female genital appendages and characteristic body form, it is very similar to Thinodromus. The age of the island is rather young. How this taxon got there and what it's ancestor was is therefore open to speculation. Ochthephilus MULSANT et REY, 1856 Ochthephilus MULSANT ct REY, 1856 (type species: Ochthephilus flexuosus MULSANT ct REY, 1856) Ancyrophorus KRAATZ, 1857 (type species: Trogophloeus omalinus ERICHSON, 1840) Misancyrus DES GOZIS, 1886 (type species: Ancyrophorus emarginatus FAUVEL, 1871) Psilotrichus LUZE, 1904 (type species: Psilotrichus elegáns LUZE, 1904) Ochthephilinus ElCHELBAVM, 1915 (type species: Ochthephilus flexuosus MULSANT et REY, 1856) Stictancyrus SCHEERPELTZ, 1950 (type species: Ochthephilus flexuosus MULSANT et REY, 1856) Description - Small to medium-sized (2.0-5.0 mm), usually dark brown, but some species reddish coloured, with the smallest ones pale yellowish brown. Elytra parallel-sided, temples developed, abdomen broadest at (or around) the 6th segment. Tergum VIII with characteristic formation, often very useful in distinguishing species. The difference between sexes in the formation of sternum VIII is often very small, sexes are hard to recognize (males usually have broader tip of terminalia). - Head.
