Type species Lamellipalpodes annandalei Maulik, 1921 (by monotypy)

Diagnosis. Lamellipalpodes can be distinguished from other genera in the subfamily Ototretinae by the combination of the following characters: posterior pronotal angles with a circular pit near apex, terminal palpomeres of maxillary and labial palpi considerably elongate, leaflike, antennae more or less filiform, antennal branches absent, mandibles small considerably shorter than head width (in comparison to Lamellipalpus Maulik, 1921 ) and in male genitalia with parameral apices more or less rounded (never medially emarginate as in Lamellipalpus ).

Redescription. Body oval, densely pubescent. Head partly hidden by pronotum, eyes small, hemispherical, distance between eyes 1.6– 2 x longer than eye diameter in lateral view. Antennae filliform ( Figs 10–18 View FIGURES 10 – 18 ). Mandibles small to medium-sized, slightly longer than width of labrum, strongly hooked. Terminal palpomeres of maxillary palpi oval, flattened, over 8–15x longer than palpomere 3, terminal palpomeres of labial palpi enlarged. Mandibles slightly arcuate, as long as to1.5x longer than eye diameter. Pronotum transverse, almost 1.6– 2 x wider than long ( Figs 19–27 View FIGURES 19 – 26 View FIGURES 27 – 42. 27 ), anterior margin arcuate, anterior angles rounded, posterior angles projected posteriad, with a circular pit near apex, posterior margin bisinuate, median portion of pronotum with longitudinal groove. Pronotum shining, finely punctured, sometimes setose. Scutellum triangular. Elytra irregularly punctured, widest medially, slightly tapering apex. Each elytron 2.8–4.5x longer than humeral width ( Figs 1–9 View FIGURES 1 – 9 ), bearing 3–4 sometimes inconspicuous costae. Terminal abdominal sternum with large proximal aperture, truncate proximally. Terminal and penultimate tergum fused, jointly trilobed, penultimate tergum with proximal projection, terminal tergum apically emarginate. Aedeagus with widely U-shaped, hemispherical phallobase, phallus with oblique to longitudinal plate in median portion ( Figs 43–60 View FIGURES 43 – 60 ), distal portion of phallus laterally compressed, base of phallus with 2 strong angular projections. Parameres as long as to slightly longer than phallus, convex laterally, parameral apices projected inward, apices approaching to sometimes in contact, bases of parameres separated by transverse process dorsally, phallus with furcate projection basally. Terminal abdominal sternum with large proximal aperture, terminal tergum apically emarginate, fused to penultimate tergum ( Figs 28–42 View FIGURES 27 – 42. 27 ). Body length: 4–6.5 mm, humeral width: 2.0– 2.5 mm. Immature stages and females unknown.
