Creberulidia gentingensis Yang & Zhang sp. nov.

( Figs 5–8 , 16–23 )

Description. Head yellow-brown; ocelli dark brown; outer margins of eyes dark brown, inner areas dark reddish-brown ( Fig 5, 7 ); face light brown, clypeus with red-brown longitudinal stripes on both sides, underneath antennal socket along lateral frontal suture to the base of clypellus dark brown ( Fig. 7 ); pronotum light brown, densely covered with yellow spots; mesonotum dark brown with sparse yellow spots ( Fig. 6 ); forewings yellow-brown, with veins dark brown and yellow spots ( Fig 5, 8 ).

Head with crown anterior margin broadly rounded ( Fig. 8 ); clypeus with transverse impressions on both sides ( Fig. 7 ); mesoscutum large; scutoscutellar sulcus arc-shaped, distinctly concave ( Fig. 6 ).

Male genitalia: Pygofer in lateral aspect approximately triangular, with a small caudodorsal lobe, caudoventral margin folded inward, covered with short setae ( Fig. 16 ); 10th segment narrow and long, without ventral processes ( Fig. 23 ); subgenital plate elongated, slightly constricted subbasally, outer margin weakly sclerotized subapically, apex with some short, hairlike setae, without spines ( Fig. 19 ); dorsal connective long and cylindrical, approaching middle of aedeagal shaft ( Fig 20, 22 ); aedeagus long, flat, asymmetrical, slightly sinuate in lateral aspect, apex toothed in lateral aspect, with 2 projections originating from same side subapically, projection close to apex with 4 secondary processes of varying lengths, the other one bifurcated ( Fig 20, 21 ), shaft with numerous teeth in distal ⅓ arranged in close tufts and distinctly inflated medially; gonopore small, situated distad about ⅓ of shaft, exiting laterally ( Fig. 22 ); connective broadly Y-shaped, arms longer than stem ( Fig. 17 ); style short and small, broad basally and gradually tapered apically, almost finger-like ( Fig. 18 ).

Measurements. Male body length 8.72 mm; crown length×width 0.74× 2.14 mm; eye width 0.75 mm; frontoclypeus length 1.67 mm; clypellus length 0.92 mm; pronotum length×width 1.02× 2.63 mm; mesonotum + scutellum length 1.57 mm.

Material examined. Holotype: ♂, Genting Highlands , Pahang, Malaysia, 16 Jul. 2023, 3°25'26.5728"N, 101°47'37.9932"E, 2000 m, collected by Hongfen Zou.

Etymology. This new species is named after its type locality, Genting Highlands.

Remarks. This species is morphologically close to Creberulidia barnesi (Nielson) , but can be distinguished by 1) aedeagus with 2 projections originating from same side subapically, one close to apex with 4 secondary processes of varying lengths and the other one bifurcated, 2) shaft with numerous teeth in distal ⅓ arranged in dense groups.
