Sabahanus gen. nov.

(URN:LSID:ZOOBANK.ORG:ACT: D382324F-F98E-4808-ACC0-49C51888F212)

Type species: Sabahanus ornamentus sp. nov.

Description: Body stramineous or ochraceous with conspicuous orange markings on head and thorax. Forewing with longitudinal orange bands basally, apical cells marked with brown, veins with a few scatered dark brown spots. Fore and hind tibia with setal bases dark brown.

Head shorter than pronotum with two anterior carinae. Crown angularly produced with middle length longer than next to eyes, slightly transversely sulcate subapically; coronal suture distinct; faintly longitudinally striate. Ocelli slightly larger than twice their own diameter from eyes. Face slightly shorter than long; antennae situated near upper corner of eye in facial view, longer than half-body length; antennal pit deep and slightly encroaching on to clypeus; lateral frontal sutures well developed, evenly curved from above antennal pits to ocelli; gena slightly incurved below eye. Pronotum shorter than mesonotum, with carina on lateral margin. Forewing slightly tapered distally to apex, with appendix well developed; four apical cells and three subapical cells, inner subapical cell open, claval veins indistinct. Hindwing with four apical cells and two transverse veins. Fore femur setal formulation: IC = 12; AM1 close to middle. Fore tibia with PD:AD = 2:4; hind femur setal formula: 2 + 2 + 1.

Male genitalia: Anal tube long. Pygofer produced acutely to apex with some macrosetae on lateral lobe, posterior margin sinuated in profile. Valve pentagonal. Subgenital plate with lateral margin convex in basal half with three to four lateral macrosetae in close oblique row, apex long and digital. Style with pre-apical lobe rectangular, apical process moderately robust, beak-like. Connective short, articulated with aedeagus, stem approximately as long as arms. Aedeagus with dorsal apodeme well developed, apex bifurcate in dorsal view; shaf elongate cylindrical, gonopore subapical on dorsal surface; base of aedeagus with a pair of ventral processes.

Distribution: Malaysia (Borneo).

Remarks: Tis genus is externally similar to Roxasella -group and previously treated as an undescribed group list in ‘unplaced’ (Supporting Information, Table S1), but can be distinguished externally by its bright orange markings on the head, pronotum, and forewings. It differs from the other paraboloponine genera in the male genitalia by the short oblique row of three to four macrosetae on the subgenital plate (with their bases darkly pigmented) similar to Tenompoella Zhang and Webb but in this genus the aedeagus is disassociated from the connective.

Etymology: Te genus is named for the collecting locality of its type species ‘Sabah’.
