Lamprobityle zeltitae sp. nov.

( Fig. 4 )

Type material. Holotype. Female: Philippines: Mindanao Isl. , Cabanglasan, Bukidnon, 06.2014, local collector leg. Deposited in the DUBC . Paratype. Female. Philippines: Mindanao Isl. , Bukidnon, 11.2013, local collector leg. ( DUBC) .

Description. Body length 9.0–11.0 mm, width 3.5–4.5 mm. Body black, surface roughly dotted and in some places covered with fine tomentum. Elytra with thin transverse stripe covered by white tomentum. Legs and antennes black.

Head small, black, glossy and covered with greyish tomentum. Clypeus and labrum black and glossy. Facial part with many outstanding setae. Head in frontal part with fine microsculpture, with small transverse and slightly convoluted stripes and in some places with very gentle reticulate microsculpture. Eyes large, double-lobed; they surround elevated antennal bases from one side. Forehead between antennal bases sunken, with narrow longitudinal corrugation covered with greyish tomentum. Antennes relatively long and thin, not reaching apex of elytra at females. Many antennomeres covered with fine tomentum and long setae. Antennomeres I and II black, with slightly bluish metallic gloss. Antennomere III black, dentiformly enlarged and thicker in apical part. Gloss darker in widest part of flagellum, therefore it looks like bichromatic. Residual antennal segments dark and covered with silver-grey tomentum, at their apices slightly darker.

Pronotum cylindrical, slightly wider than long, in posterior border completely marginated with transversal furrow. Surface of pronotum strongly and sparsely puncturated, with fine and sparse tomentum. Scutellum black, round at apex, with pale tomentum in medial part. Both sides of pronotum at posterolateral angles covered with dense silver-grey tomentum.

Elytra long, well developed, without parallel edges; elytra slightly narrowed between humeri and middle part, slightly widened behind middle, widely rounded at their apical part. Elytra roughly dotted, broadly impressed between humeri and medial parts of each elytron. Dent contains narrow transverse stripe covered with white tomentum; with convex protuberances behind humeri. One fourth of base black, with very fine sparse tomentum. Residual elytra covered with fine grey and in some places sparse tomentum.

Legs short, robust, black, with bluish or aeruginous gloss. Apex of profemori strongly widened, slightly darker. Legs mostly with dark tomentum and setae. Tarsi black, with bluish gloss. Tarsomeres flattened, covered with short or long, light or dark tomentum and setae.

Ventral side of body dotted, covered with silver-grey tomentum.

Differential diagnosis. This species differs from all other currently known congeneric taxa by the shape of elytra. It is slightly similar to L. (s. str.) fasciatus (Vives) and L. rugulata (Vives) from Luzon Island, but L. zeltitae sp. nov. has more convex and protruding elytral protuberances that are situated behind humeri. Moreover, a new species has a white narrow transverse stripe at the elytra. New species is similar also to L. mindanaoensis Barševskis & Jaeger , which differ by the morphological characters specified in the determination key below.

Distribution. Philippines: Mindanao Isl. This species is probably endemic for the Mindanao island.

Etymology. The species is named in honour of my wife Zeltīte Barševska, in gratitude for her great support.
