Archiclaviger overbecki Heller, 1936 ( Figs 4 , 5C )

Archiclaviger overbecki Heller, 1936: 67 .

Type material examined. Lൾർඍඈඍඒඉൾ (by present designation): INDO- NESIA: ♀, with six labels ( Fig. 4G ): ‘südl. M.- Java, Djokakarta (= Yogyakarta), H.Overbeck / 1933, 6 / Staatl.Museum für Tierkunde, Dresden / Archiclaviger overbecki H Typus / Archiclaviger overbecki HELLER / Archiclaviger overbecki Heller, Cl. Besuchet , det. v. 1982, ♀ ’ ( MDT).

Diagnosis. Female. Body ( Fig. 4A–C ) length 2.23 mm; dorsal surface of head, pronotum, elytra and basal third of abdomen with evenly distributed, short setae; venter of head lacking carinae ( Fig. 4E ); antennomeres 1 (scape) and 2 (pedicel) short, antennomeres 3–6 elongate ( Fig. 4F ), antennomere 6 broadening from base toward apex, apex truncate and densely setose ( Fig. 4D ); both posterior margin of elytra and basal cavity of abdomen with row of long, golden setae; disc of abdomen moderately convex dorsally ( Fig. 4C ), composite tergite with linear microsculpture and scattered long, thick golden setae ( Fig. 4A ); sternite 2 (IV) along middle twice as long as sternite 1 (III), and approximately as long as sternite 3 (V) ( Fig. 4B ).

Lectotype designation. In the original description, Hൾඅ- අൾඋ (1936: 67) gave ‘(♀?)’, indicating doubts about the sex of the examined material. Although the type material comprised possibly only a single specimen, the presence of more specimens cannot be excluded. Therefore, in the interest of the stability of nomenclature and to provide a unique name-bearing type, we designate here the examined female as the lectotype.

Distribution. Indonesia: Java ( Fig. 5C ).
