Dongodytes (s. str.) baxian Tian, 2011: 62

Diagnosis.

Middle sized, head and pronotum sparsely covered with erected setae, elytra glabrous; head (Fig. 16) extremely elongate though comparatively stout, and gradually narrowed towards neck constriction; only anterior pair of supraorbital setae present; clypeus quadrisetose; head (excluding mandibles) plus prothorax distinctly shorter than elytra; pronotum with two pairs of latero-marginal setae, posterior ones at a little before hind angles; lateral borders near front angles clearly visible from above, hind angle rectangular and sharp (Fig. 27); 3rd elytral stria with three dorsal pores, at about 2/7, 1/2 and 1/7 from base, respectively; marginal umbilicate pores: distance from 2nd to 3rd longer than half from 1st to 2nd, distance from 4th to 3rd as long as that from 3rd to 5th; male genitalia stout, nearly straight, base orifice very wide, with a small sagittal aileron, dorsally apical lobe broadly rounded; each paramere with four long setae at apex.

Material examined.

Only the male holotype ( Tian 2011).

Distribution.

Guangxi ( Du’an). Known only from the limestone cave called Baxian Dong, Chengjiang (Figs 1f and 73j).

Baxian Dong remains its natural state in some degree though it is located in Baxian Park close to Chengjiang. However, the species Dongodytes (s. str.) baxian is very rare. We visited the cave twice in June and December, 2013 respectively, but failed to collect any additional specimens. Major parts of the big cave are too dry, except for a small area at about 40 m from the upper entrance where water droppings create a suitable habitat for trechines.
