Lambirocerus View in CoL gen. nov.
Type species: Lambirocerus cycloformulus sp. nov.
Robust, ochraceous. Head wider than pronotum. Coronal suture absent, crown finely rugose, with median length slightly longer than length next to eyes. Face slightly wider than long; lateral frontal sutures short, straight, not reaching ocelli; ocelli closer to midline than to corresponding eye and near midheight of eye in facial view; gena with straight lateral margin, not incised below eye; lorum broad; rostrum not reaching hind coxae; anteclypeus surpassing apex of gena, apex wider than base, lateral margin straight ( Fig. 1D View FIGURE 1 ). Pronotum shagreen, declivous anteriorly, 2.8 times wider than long. Combined length of mesoscutum and scutellum longer than pronotum, median sulcus obviously angulate. Forewing with 4 apical and 2 subapical cells, r-m1 and m-cu1 crossveins present, outer apical cell largest, adjacent apical cell smallest and parallel sided; clavus with two veins; appendix broad and extended to wing apex, bordering inner two apical cells ( Fig. 1E View FIGURE 1 ). Fore femur with few short and fine setae. Fore tibia with several stout and long AV and PV setae on distal half, fine setae on basal half. Hind tibia with 19–20 setae on row PD, 6 setae on AD and 6 setae on apical half of AV. Hind femur with 2+1 apical setae. Hind basitarsus with two platellae.
Male genitalia. Male pygofer dorsal margin with broad basal apodeme ( Fig. 4A View FIGURE 4 ). Segment X unsclerotized; sclerotized basal collar absent. Connective slender, I-shaped, stem longer than combined width of arms, median anterior lobe acute ( Fig. 4C View FIGURE 4 ). Style well-developed, apophysis short and stout, curved at right angle relative to base, with lamelliform lateral lobe at bend ( Fig. 4I View FIGURE 4 ). Aedeagal shaft long and slender, attenuated in lateral view, apex bifurcate in posterior view; gonopore subapical on ventral surface ( Figs. 4E–H View FIGURE 4 ).
Distribution. Malaysia ( Sarawak).
Etymology. The masculine generic name is named for the type locality (Lambir Hills National Park).
Remarks. Lambirocerus is similar to Paraidioscopus Maldonado-Capriles ( P. tagalicus and P. harrisi ) in the slender aedeagus and forewing venation, but this new genus can be distinguished from Paraidioscopus by the broad style, having a lamelliform lobe at the bend and the aedeagus apex bifurcate, without elongate processes.
