description: Agrilus calabai sp. nov.
(Fig. 1A)
Description of holotype. Size: 10.5 mm. BODY. Shape: cuneiform; Build: robust; Color (dorsally): unicolored. HEAD. Size: very large; Modification: strongly convex; Medial impression: shallow. Frons: Outline: markedly protruding head outline. Vertex: Sculpture elements: rugae; Sculpture aspect: arcuate; Sculpture density: dense.
Eyes: Size: smaller than half width of vertex (dorsal view); Shape: markedly protruding head outline; Lower margin: in line or below antennal socket; Median orbit: converging ventrally. Antennae: Length: reach to about anterior pronotal angles; Serration: from antennomere 4. PRONOTUM. Shape: visually transverse; Sides: markedly arcuate; Maximal width: at middle; Anterior margin: narrower than posterior. Anterior lobe: Development: obvious; Shape: arcuate; Position: projecting beyond anterior angles. Posterior angles: Shape: obtuse; Apex: sharp. Disk: Convexity: strongly convex; Impressions: medial and lateral; Medial impression: anteromedial and posteromedial; Lateral impressions (depth): deep; Lateral impressions (modification): with tomentose patches. Prehumerus: Development: carinal; Shape: bisinuate; Extent: beyond 1/2 of pronotal length; Anterior end: adjoining to lateral carina; Posterior end: distant from posterior angle or margin; Arc: obvious. Lateral carinae: Convergence: moderate; Junction: absent; Narrowest point: at posterior 1/5–1/4 of marginal carina; Modifications: submarginal carina anteriorly and posteriorly obliterate. Scutellum: Size: robust. ELYTRA. Color: unicolored; Humeral carina: absent. Apices: Arrangement: separate; Shape: spinate; Number of cusps or spines: 1; Position of dominant projection: medial. Pubescence: Pairs of tomentose spots: humeral, medial, apical. STERNUM. Prosternal lobe: Size: large; Distal margin: arcuately emarginate; Emargination (depth): deep; Emargination (width): wide. Prosternal process: Width: wide; Shape: subparallel; Sides: straight; Angles: obtuse; Disc: flat; Projection (length): protruding distinctly beyond angles. Metasternum: Metasternal projection: impressed. ABDOMEN. Tomentum: present. Last ventrite: Disk: with medial carinula. Sternal groove: Extent: on apical ventrite; Shape on apex of last ventrite: arcuate. LEGS. Metatarsus: Length to metatibia: distinctly shorter. Metarsomere 1: Length to following tarsomeres: longer than 2–3 but shorter than 2–4.
Variability. Unknown. The species is known only from the female holotype.
Diagnosis. A. calabai is distinctive by obviously convex head with narrow longitudinal impression; by prominent anterior pronotal lobe projecting far beyond anterior angles and by the size of humeral spots on elytra which are distinctly larger then the medial and apical ones.
Type material. Type locality: Indonesia, Nusa Tenggara Barat, NE Sumbawa, Calabai (Tambora National Park) [08°13'S, 117°44'E]. Type specimens. Holotype ♀ (EJCB): “ Indonesia, NE Sumbawa, Calabai (Tambora N.P.), 11–13 Feb 1994, Bolm lgt.”.
Distribution. Indonesia (Nusa Tenggara Barat (Sumbawa Island)).
Etymology. The specific name is a noun in apposition derived from the type locality “ Calabai ”.
