Velarifictorus (Velarifictorus) bannaensis – Chen et al. 2018: 502. — Zhao & Liu 2022: 247. Diagnosis Body size is medium within the genus. S1 and S2 are absent (Fig. 7E–F), S3, S4 and S5 are present (Fig. 10J–K), S6 is absent (Fig. 4J–K). Male. One short vertical line is present below middle ocellus (Fig. 7E–F); tegmina are slightly shorter than the end of abdomen, with the apical field being rather prolonged (Supp. file 1: Fig. S6J); medial process of epiphallus has two half-lobes with the lateral margin concave inward (Fig. 12M–N). Female. Ovipositor exceeds the length of the cercus (Supp. file 1: Fig. S9O). Material examined CHINA • 2 ♂♂, 1 ♀; Yunnan, Gongshan, Dulongjiang, Maku; 27°41′18.031″ N; 98°16′51.784″ E; 21 Jun. 2015; Wen-Xuan Bi leg.; ECNU 506 to ECNU 508. Redescription Male Brachypterous. Body medium-sized. Head round, almost equal to pronotum in length; S1 absent (Fig. 7E–F); S2 absent (Fig. 4J–K); posterior area of the head densely covered with short hairs, S3 to S5 present (Fig. 10J–K); S6 absent. Eyes oval, contiguous with antennal sockets; ocelli arranged in an inverted triangle, below middle ocellus with one short vertical stripe. Antennal sockets located in the middle of frons, approximately triangular. Clypeus rather smooth, median part of epistomal sulcus slightly concave. Mandible shorter than other parts of head (Fig. 7E–F). Fifth segment of maxillae palpus finger-like, third segment of labial palpus slightly swollen. Pronotum: rectangular, transverse, anterior margin slightly concave, posterior margin slightly convex, anterior and posterior margins with setae, dorsally covered with short setae, both sides with dot-like patterns, median with 1 groove near anterior part. Tegmina with two oblique veins; mirror nearly rectangular with 1 arched vein inside; apical field rather prolonged (Supp. file 1: Fig. S6J). Hind tibiae: 5 spurs on the outer side, 5 spurs on the inner side, and 6 apical spurs. Genitalia: epiphallus transverse. Medial process of epiphallus bilobed with two half lobes, apex with one depression; lateral margin of medial process with one curved inward concavity (Fig. 12M–N). Lateral lobe of epiphallus sheet-like, anterior side relatively straight, posterior side curved dorsad in an arch, gradually narrowing from base to apex, apex rounded with setae (Fig. 16M–N). Ectoparamere lobe-shaped, curved dorsad, gradually narrowing from middle to apex, apex acute; inner margin at one-third of distance from the apex blunt (Fig. 15M–N). Female Brachypterous. Similar to male brachypterous in appearance (Supp. file 1: Figs S1O, S 5C). An indistinct stripe extends above the epistomal sulcus, between median ocellus and epistomal sulcus with one indistinct longitudinal stripe (Supp. file 1: Fig. S3F). Tegmina slightly shorter than apex of abdomen (Supp. file 1: Fig. S10O). Ovipositor longer than cercus (Supp. file 1: Fig. S9O). Coloration Body brown; eyes black, ocelli yellow; antennal sockets yellow; frons black; vertex stripes yellow; pronotum with yellow spots; inner and outer sides of hind femora with dark brown oblique stripes or irregular spots.
