( Fig. 113 )

Geodromicus sinuatocollis Bernhauer, 1938b: 50 Type material examined (1 ♀): Holotype ♀: [The specimen without left antennomeres 3–11 and right antenno- meres 4–11, left protarsus and right mesotarsus]: ‘Nanye`li | 17.ix.[19]29’ <rectangular label, handwritten in black Indian ink>, ‘N[orth]. Tcheuly | China. [E.]Licent | Becquartdon’ <rectangular label handwritten, in black Indian ink>, ‘ sinuatocollis | B[e]rnh[auer]. Typus | unic.’ <rectangular label, handwritten in black Indian ink>, ‘pr. sinuatus Sh [arp].’ <rectangular label, handwritten in black Indian ink>, ‘ sinuatocol - | lis Bernh. | Typus unic.’ <yellow rectangular label, handwritten in black Indian ink>, ‘ Geodromicus | sinuatocollis Bernhauer, 1938 . | A. Shavrin. det. 2009’ <rectangular label, printed> (FMNH).

Remarks. The species was described by Bernhauer (1938) from “Tcheuly-Nord: Nanye-li […]” and up to the present time it is known only from the holotype. Measurements of the holotype: HW: 1.00; HL: 0.80; OL: 0.30; TL: 0.15; 4: 0.13 × 0.05; PL: 1.10; PW: 1.30; ESL: 1.90; EW: 2.00; AW: 2.20; MTrL: 0.63 (MTrL 1–4: 0.38; MTrL 5: 0.25); BL: 5.80. In general appearance, G. sinuatocollis is very similar to G. sinuatus (Sharp, 1889) from Japan, from which it differs by a less convex body, larger and coarser punctation of the forebody, a scutellum without microsculpture, and by slightly shorter segments of antennae. The distinguishing characters listed above are generally variable in most species of Geodromicus , but the synonymy of G. sinuatocollis with G. sinuatus is not proposed here because additional material (including males) from northern China is required. The distribution of the species is shown in Fig. 113 .
