Kavanaugh collector”. All paratypes also bear the following label: “PARATYPE Trechus shibalicus Deuve & Kavanaugh, sp. nov. designated 2016” [yellow label]. TYPE LOCALITY.— China, Yunnan, Fugong County, Shiyueliang Township, 8,5 km above Shibali on Shibali Road, North Fork of Yamu He, N27.18416°/E98.72026°, 3100 m. DERIVATION OF SPECIES NAME.— The species epithet, shibalicus, is derived from the name of settlement, Shibali, at and near which specimens of the type series were collected, and the Latin adjectival suffix, -icus, meaning belonging to or pertaining to. DIAGNOSIS.— Adults of this species (Fig. 24a) can be distinguished from those of all other species in the region by the following combination of character states: size small (BL = 3.3 to 3.5 mm), apterous; body color reddish brown; tempora glabrous, short and distinctly convex; pronotum transverse (ratio Pw/PL = 1.44), basal angles rectangular or slightly acute and sharp; elytra with striae finely punctate, lateral striae more or less effaced, recurrent stria abruptly interrupted at slight convexity at posterior end of stria 7, two typical discal setae present, preapical seta present and inserted in a discal, forward position near apical one-fourth of elytra on interval 3 next to stria 2; male aedeagus with sagittal aileron present but reduced, apical lamella slender with blunt apex, endophallus with a distinct scaly area.
