Differential diagnosis. Apterodela lobipennis is readily distinguished from A. bivirgulata by the well-developed, especially in males, subapical sinuate notch, the narrow white elytral pattern ( Figs 193–198 vs. Figs 155–162 and Figs 173–179 ; Figs 203–210 vs. Figs 165–172 and Figs 183–189 ), by the flatter body ( Fig. 172 ), by the shape of aedeagus ( Figs 220, 221 vs. Figs 214–219 ; Fig. 232 vs. Figs 228–231 ) and by the internal sack especially by small BLR ( Figs 240 , 254 , 261 vs. Figs 238 , 252 , 259 ). Apterodela lobipennis is best distinguished from A. kazantsevi and A. latissima sp. nov. by the narrower elytra, the shallower subapical notch ( Figs 193–198 vs. Figs 199–201 ; Figs 203–210 vs. Fig. 211 ), and by the shape of aedeagus ( Figs 220, 221 vs. Figs 222, 223 ; Fig. 232 vs. Fig. 233 ), and additionally from A. kazantsevi by the wider pronotum ( Figs 124–127 vs. Fig. 133 ; Figs 129–132 vs. Fig. 133 ; Fig. 274 ). From A. alopecomma sp. nov. A. lobipennis is distinguished by the shape of labrum ( Figs 85–87 vs. Fig. 95 ; Figs 90–92 vs. Fig. 100 ), by the shape of elytra, and white elytral pattern ( Figs 193–198 vs. Fig. 202 ; Figs 203–210 vs. Fig. 212 ) as well as by the shape of aedeagus ( Figs 220, 221 vs. Fig. 224 ; Fig. 232 vs. Fig. 234 ).

Redescription. TL = 14.0– 16.4 mm (mean = 15.2 mm, n = 28) in males ( Figs 19, 21 ), 15.5–18.0 mm (mean = 16.43 mm, n = 14) in females ( Figs 18, 20, 22–24 ), 17.0 mm in neotype, 18.0 mm in the original description ( Bates 1888: 381); body relatively flat, especially in males ( Figs 274–276 ; Table 1 )—TL/BH = 3.92–4.78 (mean = 4.34, n = 28) vs. 3.62–4.22 (mean = 3.87, n = 13).

Antennae projected posteriorly over basal quarter of elytra; antennomeres 1–4 metallic bronze or bronze-cupreous with greenish-gold or golden-cupreous reflection, scape except for single apical seta glabrous ( Figs 51–53 ). Labrum transverse, LW/LL = 1.82–2.4 (mean = 2.05, n = 28) in males, 1.5–2.0 (mean = 1.75 mm, n = 14) in females; unidentate, with long stout apical tooth in females and short tooth in males, with 3–8 submarginal setae ( Figs 85–87, 90–92 ).

Thoracic segments deep bronze or greenish-bronze with purple-green, cupreous-green, golden-cupreous, or cupreous reflection, glabrous, coarsely rugose; mid-episternum of males clearly rugose ( Fig. 148 ), in females finely rugose. Legs metallic bronze with cupreous-green or purple-cupreous reflection.

Elytra greenish-bronze, bronze-cupreous, or deep-bronze with purple-cupreous or cupreous-green tinge, with numerous, dense diffused, small blue punctures as well as with subhumeral, subsutural and double subapical rows of large green, bluish-green or golden-green setigerous pores; flattened, with relatively wide flat, lateral margins between humeral and apical portions; EL/EW = 1.66–1.8 (mean = 1.74, n = 28) in males, 1.51–1.7 (mean = 1.65 mm, n = 15) in females; with distinct smooth subapical sinuate notch in both sexes, but more developed in males; apices in females clearly wider than in males. Shoulders narrow, distinctly sloping, EW/EHW = 1.44–1.79 (mean = 1.61, n = 45); scutellum large, bronze-cupreous; humeral group of series umbilicata consists of 7–8 large setigerous pores ( Fig. 148 ); epipleura broad, deep bronze, with blue tinge, in some specimens with green or cupreous-green bottom edge.

Distribution. CHINA: Anxui, Hubei, Hunan, Jiangxi, Zhejiang Provinces ( Fig. 280 ).

Notes. Cicindela lobipennis was described from a single female from Kiu-Kiang ( Bates 1888). Thus, according to the Article 73.1.2 of ICZN (1999) this female is the holotype by monotypy. In the collection of BMNH one male with the label “Kiu-Kiang” is housed ( Figs 9, 10 ). However, the handwriting on this label is not of Bates because the “ i ” is dashed, but not dotted as on the labels of Bates (see Horn et al. 1990; Moravec 2015). In addition, the sex of the museum’s specimen is not the same as in the holotype, and the shape of its elytra does not correspond to the original description “ … elytris elongato-ovatis, lateribusacute carinatis, epipleuris latis intus obliquatis paullo ante apicem terminatis, ibique margine subito depresso, apice ipso producto, quasi lobato … ” ( Bates 1888). Thus, this specimen cannot be regarded as the type of C. lobipennis . At the same time, in the collections of MNHN ( Figs 18 , 205 ), SDEI ( Figs 16, 17 , 203 ) and MFNB ( Fig. 204 ) the females labelled as “Kiu-Kiang” are housed (see the sections “Type material” and “Additional material”). However, according to the style of the labels none of them is the type of C. lobipennis , but all of them closely correspond to the original description. Based on these details, we assume that the type of C. lobipennis is most likely lost. According to the Article 75 of ICZN (1999) among mentioned above specimens a female with the labels “Kiu-Kiang, Heyne”, “ lobipennis Bates ”, “coll. W. Horn, DEI Eberswalde”, “DEI Mūnchenberg, Col – 10868” ( Figs 16, 17 ) from the collection of W. Horn (SDEI) is designated here as the neotype of C. lobipennis (see the sections “Type material”).
