The newly described species is dedicated to my friend and colleague, Michal Geiser (BMNH), one of the collectors of the type specimens, participant in several expeditions to West Africa, who prepared very interesting material of broad-nosed weevils for my study.</p> <p>Remarks. Omotrachelus geiseri is similar to three species described from Ivory Coast (O. stachi Kania, 2004, O. stelmahersi Kania, 2004 and O. tomczyki Kania, 2004) in having a moderately large body with the base of elytra only slightly constricted. From all three species O. geiseri is easily distinguishable by the following characters: epifrons at base only slightly narrower than base of rostrum, in basal two thirds parallel-sided; antennal scrobes in dorsal view invisible; interstriae 9 with one small posthumeral bump, hardly visible in dorsal view; and interstriae 3 lacking tubercle behind midlength. The other three species have the epifrons at base distinctly narrower than base of rostrum, tapering apicad just from base; antennal scrobes in dorsal view clearly visible; interstriae 9 with several irregular tubercles clearly visible in dorsal view; and interstriae 3 with tubercle behind midlength.</p> </div>	https://treatment.plazi.org/id/03B787E6C25FFF8025FDFD27FB5EFE6A	Public Domain	No known copyright restrictions apply.

Odd interstriae slightly wider than even ones; striae deep and distinct, somewhat punctured.</p> <p>Protibiae short and robust, 3.8–4.0× as long as at midlength wide, apically obliquely subtruncated, densely fringed by yellow setae, inner margin not denticulate. Tarsi with segment 2 1.2× as wide as long; segment 3 1.3– 1.4× as wide as long and 1.6–1.7× as wide as segment 2; onychium subequal to segment 3 in length.</p> <p>Penis (Fig. 15) long, 3.11–3.47× as long as wide, subparallel-sided in basal two thirds with straight or slightly rounded sides, apical portion elongated with concave sides, tip broadly rounded; in lateral view slender, weakly regularly curved, tip elongate, straight; temones almost twice as long as body of penis. Endophallus with two halfmoon-shaped sclerites, different in size.</p> <p>Spermatheca (Fig. 21) with cornu short and apically broadly rounded; corpus elongated; ramus rounded, shorter than wide; collum elongate, longer than wide, straight, slightly tapering apicad. Sternite VIII with long and slender apodeme; plate umbrella-shaped, moderately small. Gonocoxites slender, evenly tapering apicad with long apical styli.</p> <p>Biology. All specimens were collected from leaf litter using Winkler equipment, in swamp forest.</p> <p>Etymology. The subparallel-sided elytra suggested the Latin name of this new species.</p> <p>Remarks. Omotrachelus parallelus clearly differs from all other species of the genus in its small oval eyes, in lateral view placed near the middle of the head a long distance from the dorsal margin of the head, while all other Omotrachelus species have eyes large, subcircular, dorsally placed, in lateral view almost touching the dorsal margin of the head. Other specific characters of this species are as follows: semi-erect elytral setae short, conspicuously spatulate, epifrons at base as wide as rostrum, protibiae very short and robust, and tip of penis enlarging in dorsal view and distinctly curved in lateral view.</p> </div>	https://treatment.plazi.org/id/03B787E6C256FF8D25FDFE18FDEDFDDE	Public Domain	No known copyright restrictions apply.

C.- Mus. Congo, Biot. No 70, tête de source de la Mvula Myeji, forêt (RMCA). Paratype: 1 ♁, same data holotype (RMCA).</p> <p>Description. Body length 3.81–4.18 mm, holotype 3.81 mm. Elytra with interstriae densely covered with small, regularly rounded appressed scales, 4–5 across width of one interstria, with feeble goldish or cupreous metallic sheen, striae glabrous. Head with rostrum and pronotum densely covered with greyish brown, small, irregularly rounded appressed scales with several short fringes. All elytral interstriae with one dense row of semi-erect, slender, piliform setae, slightly shorter than width of one interstria, distance between them subequal to their length. Erect setae on head with rostrum and pronotum slightly shorter than half length of elytral setae, densely irregularly scattered. Scapes, femora and tibiae with identical appressed scales as those on pronotum, and with short, slender, moderately dense erect setae.</p> <p>Rostrum (Fig. 10) 1.18–1.22× as long as at base wide, at base weakly enlarged apicad, then subparallel-sided along entire length, at apex 1.06–1.08× as wide as at base; in lateral view regularly curved. Epifrons wide, at base as wide as rostrum, in basal half slightly tapering apicad with straight sides, in apical half distinctly tapering apicad, at base 1.64–1.78× as wide as at apex, between antennal insertions narrower than space between eyes, dorsally shallowly longitudinally depressed. Frons very short, glabrous. Epistome small, V-shaped. Antennal scrobes in dorsal view hardly visible only in short apical part as narrow furrows; in lateral view straight, narrow, directed below ventral margin of eye and teaching it. Vertex flat. Eyes moderately large, slightly convex and prominent from outline of head; in lateral view oval, almost reaching dorsal margin of head. Head enlarged posteriad.</p> <p>Antennae (Fig. 5) somewhat robust; scape slightly regularly curved, slightly evenly enlarging apicad, 5.2–5.8× as long as wide, at apex 0.8× as wide as club. Funicle segment 1 robust, conical, 1.3–1.4× as long as wide and 1.2–1.3× as long as short segment 2, this is 1.1–1.2× as long as wide; segment 3 1.4–1.5× as wide as long; segments 4–6 1.5–1.6× as wide as long; segment 7 1.7–1.8× as wide as long; club 1.4–1.5× as long as wide, with first segment as long as two thirds of entire club length, shiny, sparsely setose, the others very short, mat, densely setose.</p> <p>Pronotum (Fig. 5) very short and wide, 2.69–2.81× as wide as long, widest at base and evenly tapering apicad with almost straight sides; disc with rough punctures partly concealed under appressed scales, 3–4 across length of pronotum, distance between punctures shorter than their diameter; pronotum in lateral view slightly vaulted.</p> <p>Elytra (Fig. 5) long oval, 1.36–1.44× as long as wide, behind base distinctly constricted and here subequal in width to pronotum, constriction as long as length of pronotum, elytra from basal constriction obliquely subtruncate posteriad to widest point at basal third, then slightly evenly tapering posteriad with almost straight sides, apically broadly rounded; base straight; interstriae 8 and 9 with low subhumeral bump visible mainly in dorso-lateral view; interstriae 7–10 except of short subhumeral bump portion glabrous, smooth; sutural interstriae in short basal part slightly swollen. Striae moderately wide, sparsely punctured; interstriae slightly vaulted. Elytra in lateral view distinctly vaulted in short distance just from base, then flat.</p> <p>Protibiae short and robust, 4.7–4.9× as long as at midlength wide, apically broadly rounded and fringed with rusty brown setae, with dark brown mucro and in short apical portion denticulate with 5–6 small, pointed brownish spines; inner margin bisinuate. Tarsi with segment 2 1.3–1.4× as wide as long; segment 3 1.1–1.2× as wide as long and 1.2–1.3× as wide as segment 2; onychium short, 0.7–0.8× as long as segment 3.</p> <p>Penis (Fig. 16) 2.71–2.83× as long as wide, subparallel-sided in basal two thirds, evenly tapering in apical third with slightly concave sides, tip narrowly rounded; in lateral view narrow, regularly curved, tip narrow, apically narrowly rounded.</p> <p>Biology. The type specimens were collected in forest habitat.</p> <p>Etymology. The Latin name refers to the curious and exceptionally, long basal constriction of the elytra, the basal portion subequal in width to the pronotum.</p> <p>Remarks. Omotrachelus thoracomimus shares no obvious characters of the distinctive elytra with any currently known species in the genus Omotrachelus. Its long basal constriction, including the oblique sloping part reaching the basal third of the elytral length is unique. Similarly, the three lateral interstriae glabrous and smooth and dorsal part of elytra distinctly vaulted just behind base in lateral view are also unique within the genus.</p> </div>	https://treatment.plazi.org/id/03B787E6C257FF8E25FDFDF0FB4AFDA6	Public Domain	No known copyright restrictions apply.
