( Fig. 14A–O) (URN:LSID:ZOOBANK.ORG:ACT: F69D6768-B475-4631- ACE 5-3EC6E1118C19)

Diagnosis: Crown with narrow black band at anterior margin. Style apex not bilobed, with lateroapical margin convex. Pygofer with caudodorsal margin narrowly rounded. Aedeagus with two pairs of apical processes extended ventrolateral, one pair curved anterad and other curved posterad in lateral view. Fore tibia with dorsal setal arrangement of rows AD and PD 2 + 4. Fore femur IC with about 14 setae; AV with four setae.

Description: Length (including tegmen): male 7.0 mm, female 7.7 mm.

Coloration: Body yellowish. Crown with narrow black band at anterior margin, area posterad of band ochraceous except narrow pale area along posterior margin. Pronotum yellow anteriorly, greenish brown posteriorly.

Crown parabolic, anterior margin slightly more produced than posterior margin. Fore tibia with dorsal setal arrangement of rows AD and PD 2 + 4. Fore femur IC with about 14 setae; AV with four setae.

Male genitalia: Pygofer with caudodorsal margin narrowly rounded. Style apophysis weakly expanded apically, apex with inner margin obtusely angulate and outer angle acute, pre-apical lobe absent. Connective stem broad and slightly longer than arms. Aedeagus with dorsal apodeme abruptly constricted then broadened near apex in posterior view; shaf moderately long and narrow, evenly curved dorsad in lateral view, narrow and parallel sided in posterior view, with two pairs of apical processes extended ventrolateral, one pair curved anterad and other curved posterad in lateral view, both extended to near midlength of shaf, gonopore apical.

Material examined: Holotype: ♂, Malaysia: Sarawak; Gunung Mulu National Park , near headquarters (04º04. 25 ′ N, 114º81.38 ′ E), 30 June–28 July 2009, coll. S. Krishnankuty, mercury vapour lights ( INHS).

Etymology: Tis species takes its name from the Mulu National Park.

Remarks: Tis species resembles R. biarcuata in external form, coloration, and male genitalia but lacks an orange arcuate marking on the pronotum and has the processes of the aedeagus similar to each other in size.
