Makranczy, Gy.: Systematics and phylogenetic relationships of the genera in the Carpelimus group (Coleoptera: Staphylinidae: Oxytelinae)

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]. Parameres [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] arc divided into coxites, valvifers and styli. Sclerites (possible remnant of sternum X) [64] appear as small ring. - Female genitalia. Spermathcca [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 - Teropalpus contains about 10 species. The origins of this invasive genus are in the temperate Southern Hemisphere, but from there it spread to virtually everywhere in the world where major marine ports can be found. It was reported from many temperate localities in the Northern Hemisphere (e.g. England, California). Not much is known about its bionomics, but specimens are found on seashores, under driftwood and algae. Mimopaederus CAMERON, 1936 Mimopaederus CAMERON, 1936 (type species: Mimopaederus insularis CAMERON, 1936) Description - Medium-sized (3.5^4.8 mm), usually reddish dark brown to black. Body very weakly pubescent, almost bare. Temples distinct. The pronotum is conspicuously elongated and cylindrical, so that the lateral margins cannot be observed from dorsal view. Elytra significantly reduced, the species flightless. Tergum VIII with characteristic formation, often very useful in distinguishing species. - Head. Clypeus [1] well developed, epistomal sulcus [2] present. Eyes [3] not extending to the ventral portion of the head. Gular sulci [4] confluent at least anteriorly. Head [5] without dorsal midline keel. The mola [6] on the mandibles separated, well developed. Labrum [7] divided, transverse [8]. Setation behind front of labrum [9] in middle much smaller, irregular or missing. Dorsal seta [10] on epipharynx absent. Hypopharynx [11] undivided, without coriaceous field [12] on ventral side. Lateral row of bulbous setae [13] absent. Front of hypopharynx [14] not entirely covered with setae, no setae [15] on mid-line. Median sclerotized plate of hologlossa [16] anteriorly enlarged into a plate with central stick continuing till end. Last palpomere of maxillary palp [17] fully formed, strongly bulbous basally, digitiform sensillae [18] present on last palpomere, arranged [19] in parallel fashion. Apex of penultimate segment of labial palp [20] hairy. Antennae [21] straight. Antennae [22] moderately elongated. - Thorax. Prosternai process [23] pointed, scutellum [24] without pubescence, hypomera [25] exposing protrochantins. - Legs. Tibia [26] with mid-tibial spur(s), but [27] without spines or rows of stiff setae. Tarsal segmentation [28] 3-3-3 with no pseudosegment [29] and basal articles [30] compressed. Ventral setae [31] modified to form tarsal lobes, last tarsomere [32] only with sparse setae. - Elytra. Elytra [33] without puncture-rows, elytral suture [34] parallel, epipleural ridge [35] present. - Abdomen. Abdomen [36] with two pairs of laterosclerites. Intersegmental membrane [37] without brickwall pattern. Second sternite [38] fully developed, first sternite [39] completely absent. Tergal basolateral ridges [40] absent, carina [41] present at the base of second sternites. Fimbriate edge [42] on tergite VII unmodified. Tergum X [43] not divided, its dorsal struts [44] not developed, its basolateral parts [45] not fused to tergum IX. - Secondary sexual
