Morphology. Head declivous, slightly narrower than pronotum; Crown medial length 0.5 times than width between eyes ( Figs. 1F, G View FIGURE 1 ). Postclypeus slightly concave ( Fig. 1H View FIGURE 1 ). Pronotum length 1.5 times medial length of crown. Scutellum length 0.9 times medial length of pronotum ( Fig. 1G View FIGURE 1 ). Fore femur with short dorsal setae, IC row comprising 10 setae. Fore tibia with 8 setae on PD row, 7 on AD row, 18 on PV row, 25 on AV row. Hind femur macrosetal formula 2+2+1. Hind tibia with 22 macrosetae on PD row, 10 on AD row, 13 on AV row.

Male genitalia. Pygophore lobes rounded caudally with short and long macrosetae near posterior margin ( Fig. 2G View FIGURE 2 ). Valve triangular. Subgenital plate longer than length of pygofer, lateral margin sinuate with sparsely distributed setae on ventral side ( Fig. 2H View FIGURE 2 ). Connective ‘Y’-shaped, similar in length to style, arms slightly shorter than stem ( Fig. 2J View FIGURE 2 ). Style apex cheliform with developed preapical lobe, lateral margin sinuate, preapical lobe with several setae near inner margin ( Fig. 2I View FIGURE 2 ). Aedeagus simple, dorsal apodeme and preatrium plate-like, well developed, dorsal apodeme apex rounded in posterior view; shaft curved dorso-anteriorly, slightly narrowed caudally; gonopore apical ( Figs. 2K, L View FIGURE 2 ).

Measurement. Length of male including tegmen: 3.8–4.0 mm.

Material examined. Holotype ♂ (NWAFU), CHINA, Yunnan Prov., Jingdong County, 28 April 2018, coll. Lu Lin ; Paratypes:1♂( NWAFU), same data as holotype; 1♂( IZCAS), CHINA, Yunnan Prov., Nujiang Prefecture , 22 May 2009, coll. Ding Liang.

Remarks. This species is similar to R. dactyla in the male genitalia but differs in having a longer dorsal apodeme and bilobed preatrium.

Etymology. This specific epithet is from the Latin word “ hamatus ” referring to the hook shaped aedeagus in lateral view.
