Diplocheila (Neorembus) latifrons (Dejean 1831)

Diplocheila (Neorembusj) latifrons Dejean
The distinctive features of this species are the same as those given for the subgenus.
Two geographical subspecies of Diplocheila latifrons are recognized here and are distributed as follows : typical race throughout the range as outlined above excluding the Philippines, the atypical subspecies, described here as new, is known only from the island of Luzon, in the Philippines.
As surface sculpture is the same for the two subspecies, it is described here.
Microsculpture : head, lines fine, forming weakly transverse to isodiametric meshes ; meshes isodiametric on head and pronotum, strongly transverse on ventral surface of head, meshes weakly transverse on rest of ventral surface. Macrosculpture : head, postorbital area smooth, interorbital area with a few shallow lines laterally, frontal area with several oblique lines between frontal impressions, pronotum with very shallow transverse lines medially; dorsal surface generally micro-punctulate, punctures relatively more numerous on pronotum and elytra than on head; head ventrally with shallow, transverse lines, presternum crossed transversely by shallow lines, laterally with short, longitudinal lines, thoracic episterna and lateral portions of proand metasternum with zig-zag lines, abdominal sternites rugulose laterally, with longitudinal lines. Surface generally shining, head more glossy than pronotum and elytra, slightly iridescent, sclerites of ventral surface weakly iridescent.
