much smaller, irregular or missing. Dorsal seta [10] on epipharynx absent. Hypopharynx [11] divided, without coriaceous field [12] on ventral side. Lateral row of bulbous setae [13] absent. Front of hypopharynx [14] 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] reduced to a stick, digitiform sensillae [18] fused to penultimate palpomere or absent, if present, arranged [19] in parallel fashion. Apex of penultimate segment of labial palp [20] hairy. Antennae [21] straight and [22] extremely elongated (mid-antennal segments more, than 3 times as long as broad). - Thorax. Prosternai process [23] pointed, scutellum [24] without pubescence, hypomera [25] not 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 [29J and basal articles [30] compressed. Ventral setae [31] modified to form tarsal lobes, last tarsomere [32] with dense pubescence. - 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 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, not modified into clasping structure. Median face membranous [56], without apicomedial hook [57]. Parameres [58] not wrapping, without extra lobe [59], with membranous region [60], with one seta [61] each. Without visible pump and flagellum [62]. - Female terminalia. Female genital appendages [63] lost. Sclerites (possible remnant of sternum X) [64] lost. - Female genitalia. Spermatheca [65] sclerotized. Receptacle [66] divided, not associated with visible [67] spermathecal gland, tubular portion [68] not penetrating distal bulb, umbilicus [69] absent. Sclerotized "tube" [70] cannot be found. Diversity and distribution - Trogactus is presently only known from the Neotropical region, where it is represented with approximately 15 species. Most species are found in higher elevations, 1200-1800m, with a few occurring also on lower altitudes. A characteristic habitat for the species is leafpacks floating at the edge of mountain streams.
