description: <i>Geoffmonteithia</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020 (Figs. 11 H–J, 14J, 15L, 17E) <i>Geoffmonteithia</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020: 21. Type species <i>Geoffmonteithia queenslanda</i> Jin, de Keyzer et &amp;Sacute;lipi&amp;nacute;ski, 2020, by original designation. <b> <i>Diagnostic combination (Male)</i>.</b> Moderately large beetles, 30–40 mm long. Dorsum unicoloured, brown or dark brown. Sexually dimorphic dense punctures present on entire pronotum, scutellum and most of the ventral side including abdominal ventrites. Head slightly narrower than prothorax; frontoclypeal suture angulate, weakly impressed; median groove complete. Antennal tubercles prominent, rounded at apex. Eyes moderately large, weakly emarginate near antennal insertion, relatively narrowly separated dorsally. Mandibles less than 1/3 of head capsule length, not sexually dimorphic, broad at base, not bent towards ventral side and unidentate apically. Antenna extend beyond mid elytra in male. Scape about 0.7 times of head capsule length, posteriorly extending slightly beyond posterior margin of eye, gradually expanded; antennomere 3 distinctly longer than scape or antennomere 4. Mentum not fused to sub-mentum. Terminal palpomere of maxillary and labial palps weakly expanded and apically rounded. Prothorax transverse with lateral carina weak and partly invisible, feebly dentate; anterior and posterior margins with complete beads. Pronotal disc with smooth and coarsely punctate callosities on densely punctate, feebly shiny background. Prosternal process subparallel, only slightly extending beyond procoxae, rounded apically. Elytral surfaces moderately coriaceous; inner apical angle with sharp spine. Legs relatively long; femora and tibiae with rows of spines. Protibia external surface granulose, ventral surface rough with sparse spines and dense yellow setae apically; apex with pair of subequal spurs; tarsomere 3 moderately lobed, tarsomere 5 shorter than tarsomeres 1 and 2 combined. <b> <i>Description</i>. Male.</b> Length 30–40 mm. Body uniformly brown or dark brown. Head approximately as long as wide, narrower than pronotum. Mandibles shorter than 1/3 of head capsule length, weakly curved inwards, without sexual dimorphism; each mandible wedge-shaped, very thick and strong on lateral side and near the base, unidentate at apex, with one extra tooth on incisor edge. Labrum strongly concave near apex, anterior margin pointed medially with very dense setae; dorsal surface with longer and denser setae than on clypeus; labrum separated from clypeus by a deep arcuate groove. Frontoclypeal suture angulate; median groove distinct and complete. Antennal tubercles relatively prominent, apex rounded. Antenna 11-segment- ed, filiform, extending beyond mid elytra and sometimes almost to elytral apices; scape moderately long and gradually expanded, reaching beyond posterior margin of eye; antennomere 3 distinctly longer than scape, almost twice as long as antennomere 4; antennomeres 5–11 with blunt posterior angles. Eyes large, transverse, coarsely facetted, slightly emarginate near antennal foramen; narrowly separated dorsally. Submentum straight at apex, mentum well exposed. Terminal palpomere of maxillary and labial palps weakly expanded and apically truncate. Pronotum transverse, subrectangular with weak anterior angles and prominent posterior angles; anterior margin slightly emarginate medially with complete bead; posterior margin with complete bead; lateral carina weak and sometimes partially invisible with rather regular small sharp teeth. Disc surface very densely punctate and matt except for two triangular shiny, coarsely and deeply punctate admedian islands, two smaller lateral areas and transverse area in front of the posterior margin. Prosternum covered with fine and deep punctures; hypomeron well-defined, as broad as prosternal process; prosternal process parallel sided, only slightly extending beyond procoxae, rounded apically. Mesoventral process narrowing towards apex and emarginate apically. Ventral side of thorax and coxae with sparse golden hairs; metanepisternum densely setose. Metaventrite with shiny arrow-shaped area medially, finely and deeply punctate elsewhere. Metanepisternum weakly constricted at base. Scutellum rounded apically; surface very densely and finely punctate. Elytral surfaces dull covered with irregular coriaceous sculpture; two or three weak traces of venation often present on apical 2/3 of elytra; elytral apices rounded with sharp sutural spine; epipleuron complete, narrowing apically. Legs strong and relatively long; femur sub-parallel, surface rough but without obvious spines on ventral side; tibia slender and relatively flat, without spines along outer margin, bearing sensory setae on ventral side apically; each tibia with distinct apical spine and a pair of subequal of spurs. Protibia external surface granulose, ventral surface rough with sparse spines and dense yellow setae apically; tarsi strong; tarsomere 3 moderately lobed; tarsomere 5 shorter than tarsomeres 1 and 2 combined. Abdomen with ventrites 1–5 densely punctate basally with smooth and appearing less sclerotised apical part; ventral surface almost glabrous, only bearing long setae along the edge, and very densely setose on the apex of ventrite 5. Male genitalia (Fig. 14J). Tegmen longer than sternite VII; parameres moderately long, 0.16 times length of entire tegmen, rounded apically with triangular projections at the base; penis as long as tegmen, dorsal apex truncate while ventral apex acute angulate. <b>Female.</b> Antennae usually shorter than in male, only extending to middle of elytra; antennomere 3 as long as or slightly longer than scape. Pronotal disc shiny, surfaces irregular with very deep and coarse punctures; fine and dense punctures on thorax and abdomen absent. Legs much slender than in male. Abdominal ventrite 5 truncate. Ovipositor (Fig. 15L) relatively short, apical sclerosed part 3/4 length of baculus, distal gonocoxites very short and stout, with tiny lateral projection; stylus large, inserted laterally and very close to gonocoxite apex, gradually expanded apically.
