Type material.

Holotype: "Vietnam: Lao Cai, ca. 12km along road from Sapa to Lai Chau, 1950m, 22°20'58"N; 103°46'15"E, 1-12.V.1999, B. Hubley, pan traps (yellow), margin of 6m wide stream, edge of bamboo/2° forest".

Diagnosis.

Distinguished from Asiophilus phloeosinoides by the more coarsely punctured frons and pronotum, by the elytral vestiture consisting of bristle-like interstrial setae, and by the protibiae bearing 6 lateral socketed teeth.

Description:

Length 1.65 mm, 2.0 times longer than wide. Colour dark brown or black. Head. Frons weakly convex, transversely impressed just above epistoma, punctures large, nearly confluent. Scant minute setae in punctures, about 12 longer setae along the epistomal margin. Eyes three times longer (dorso-ventrally) than wide, separated above by 2.9 times their width. Antennal club large, moderately flattened and oval, with two regularly spaced oblique sutures, finely pubescent. Funiculus 5-segmented, scapus about 0.8 times as long as the length of funiculus and club combined. Pronotum 0.8 times as long as wide, distinctly constricted on anterior third, notum roughly and densely punctured, punctures subconfluent; vestiture consisting of scant minute setae in punctures and a pair of median longer erect setae. Elytra 1.3 times longer than wide, 1.9 times longer than pronotum, sides subparallel on anterior two-thirds, apex rounded. Base of elytra strongly procurved and elevated by a complete row of crenulations. Striae impressed, punctures large, deep, separated by about one-quarter their diameter. Interstriae as wide as striae, slightly elevated, rugose, shining, with irregularly sized and more widely spaced punctures about half the size of strial punctures. Interstriae 8 and 9 on posterior half more elevated and sharply crenulated; interstriae 10 reaching level of metacoxae. Vestiture on disk consisting of interstrial rows of recumbent hair-like setae separated by less than their length, strial setae minute; on declivity interstrial setae in two confused rows. Sclerolepidia present along entire margin of metepisternum, very small; metepisternum with scant bifid setae, densely clothed closer to endosternum. Legs. Procoxae separated by width of one coxa. Precoxal ridges short, distinct. Mesocoxae separated by slightly more than the width of procoxa, mesocoxal process vertical. Protibiae armed by 6 socketed teeth along the lateral and apical margin and one lightly curved inner mucro. Mesotibiae armed by 6 lateral, socketed teeth. Metatibiae armed by 5 lateral socketed teeth on apical half.
