Roxasella dolichospina sp.nov.

( Fig. 12A–S) (URN:LSID:ZOOBANK.ORG:ACT: BF840CBE-3D96-44BB-B35F- CB9FB9DDAF14)

Diagnosis: Crown with a narrow black band at anterior margin interrupted at middle. Connective slender and elongate. Pygofer with caudodorsal margin bluntly rounded. Style apophysis weakly expanded apically, apex rounded medially. Aedeagus with two pairs of distal processes and extended nearly to atrium. Fore tibia with dorsal setal arrangement of rows AD and PD 4 + 4; fore femur IC with about 12 setae, AV with six setae basally.

Description: Length (including tegmen): male 7.2 mm, female 8.2 mm.

Coloration: Body yellowish; crown with a narrow black band at anterior margin interrupted at middle, remainder of crown ochraceous anteriorly fading to pale yellow posteriorly. Face stramineous with narrow black band dorsally. Pronotum tan medially, yellowish laterally. Forewing pale hyaline with three small fuscous spots along commissural margin of clavus, one just distad of claval apex, two in middle of corium and two at apices of anterior branches of R.

Crown produced, parabolically rounded, distinctly longer medially than next to eyes. Fore tibia with dorsal setal arrangement of rows AD and PD 4 + 4; fore femur IC with about 12 setae, AV with six setae basally.

Malegenitalia: Pygoferwithcaudodorsalmarginbluntlyrounded. Style apophysis weakly expanded apically, apex rounded medially and acute laterally, pre-apical lobe absent. Connective relatively slender and elongate with stem much longer than arms. Aedeagus with dorsal apodeme constricted near base then evenly widened dorsad with slightly convex dorsal end in posterior view; shaf relatively short, moderately slender, evenly curved and slightly widened distad in lateral view, very slightly widened from base to apex in posterior view, with two pairs of long apical processes extended ventrolateral, one pair evenly divergent from shaf, other pair curved toward shaf in posterior view, one pair extended more anterad than other in lateral view; apex very slightly emarginate in posterior view, gonopore apical.

Female genitalia: Female sternite VII posterior margin trilobed with medial process angulate.

Material examined: Holotype: ♂, Malaysia, Sabah, FMU10, Apin apin, Keningau (05°44.31 ′ 07N, 116°45.15 ′ 72E), 1217 m, 24 April–3 May 2016, coll. Z.S. Song. Paratypes: 1♂, same data as holotype ( NWAFU) .

Additional (non-type) material: 1♀ (tentatively associated to males, see generic Remarks), same data as holotype ( NWAFU) .

Etymology: Te specific epithet, a Latinized adjective, refers to the elongate processes of the aedeagus.

Remarks: Te tentatively associated female of this species has the abdominal sternite VII similar to R. arcuata (see Remarks under R. arcuata ).
