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