Type species.

Bruneimetopus simulans Taszakowski, Kim & Herczek, sp. nov.

Diagnosis.

Distinguished by vertical, slightly flattened head, not punctured but wrinkled and higher than wide, dorsally not extending to level of highest point of pronotum; vertex slightly convex, protruding above eye level, width of vertex equal to eye width; dorsum and pleurites of thorax with deep and dense punctures; calli slightly marked, tarsi two segmented, claw with very small, barely noticeable apical tooth; labium reaching third abdominal segment, right paramere well developed, with knee-shaped sensory lobe; left paramere ca. 1.5 times as long as right one.

Description.

Male. Body oval, slightly elongate (Fig. 6A ). Head higher than wide, dorsally not extending to highest point of pronotum, slightly flattened, impunctate but wrinkled. Antenna thin (particularly segments III and IV). Labium reaching third abdominal segment. Pronotal collar with row of punctures posteriorly. Pronotum distinctly punctuate, calli slightly marked, separated by shallow fossa. Scutellum slightly convex, baso-medially clearly depressed. Thoracic pleura distinctly punctate. Ostiolar peritreme small, moderately convex and covered with very fine spines (Fig. 8 ). Mesofemora with five, metafemora with six trichobothria (Fig. 7F, G ). Tarsi two segmented, claws with very small, barely noticeable apical tooth (Fig. 7D, E ). Genitalia: genital capsule trapeziform (Fig. 9A ), aedeagus delicate, endosoma sacciform and membranous, very weakly sclerotized inside, outer subapical and apical part more sclerotic, clothed with dense spinules (Fig. 9A, D ). Left paramere scythe-shaped, sensory lobe with several long setae, apical process elongated (Fig. 9A, B ); right paramere left paramere ca. 1.5 times as long as right one, with knee-shaped sensory lobe (Fig. 9C ).

Remarks.

Affiliation of Bruneimetopus to the Gigantometopini is clearly confirmed by the same set of features as for Planicapitus (see above). It is also indicated by presence of six metafemoral trichobothria (the specimen of Planicapitus luteus is devoid of hindlegs).

As in the case of Planicapitus , set of features mentioned in the diagnosis clearly differ the new genus from other genera belonging to Gigantometopini . The newly described genera are very similar morphologically to each other. However, in addition to small differences in the proportions of body parts and coloration, they can easily be distinguished by the completely different shape and size of the right paramere. This was a premise to describe them in separate genera.

Etymology.

Name combines Brunei (the type locality) with part of the generic name Isometopus , the type genus of the subfamily.
