basolateral parts [45] not fused to tergum IX. - Secondary sexual 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] bulblike, internal sclerites [54] present, symmetrical/paired. Apical opening [55] simplified, truncated. Median face membranous [56], without apicomedial hook [57]. Paramcres [58] not wrapping, without extra lobe [59] or membranous region [60], without setae [61]. Without visible pump and flagcllum [62]. - Female terminalia. Female genital appendages [63] are divided into coxites, valvifers but no 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] can be found. Diversity and distribution - Blediotrogus contains about 5 known species. Occurs in Australia, New Zealand and Chatham Islands. Frequently found on seashores, under moist high-tide beach wrack. Pareiobledius BERNHAUER, 1934 (type species: Bledius alutellus BERNHAUER, 1934) Description - Medium-sized (2.0-3.0 mm), usually dark brown, but some species reddish. Body weakly pubescent. Elytra parallel-sided, temples distinct, abdomen broadest at (or around) the 6th segment. Tibia with spines. 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). Male macrocephaly present, but weakly expressed. - 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. Labium [7] divided, transverse [8], Setation behind front of labium [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] present. Front of hypopharynx [14] not entirely covered with setae, no setae [15] on mid-line. Median sclerotized plate of hologlossa [16] composed of central stick with intermediate plate-like enlargement. Last palpomere of maxillary palp [17] fully formed, strongly bulbous basally, digitiform sensillac [18] present on last palpomere, arranged [19] in parallel fashion. Labial palp [20] not hairy. Antennae [21] straight. Antennae [22] moderately elongated. - Thorax. Prosternai process [23] pointed, scutellum [24] without pubescence, hypomcra [25] not exposing protrochantins. - Legs. Tibia [26] with midtibial spur(s) and [27] spines or rows of stiff setae. Tarsal segmentation [28] 4-4-4 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] not present on any stemites. 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 characters. Macrocephaly [46] present, macrothoracy [47] absent.
