Comment

The original description of Dysanabatium jacobsoni is based on an unspecified number of syntypes from Java (Bernhauer 1915[1]). Two syntypes, a female without head and pronotum labelled as “Type” and a male labelled as “Cotype” from the Bernhauer collection were studied by Rougemont (1997)[2]. For illustrations of the habitus and the male and female sexual characters see Figs 1B–H, 3A–P, and 4.
As was already observed by Rougemont (1997)[2], this species is subject to enormous intraspecific variation of external characters (Figs 1B–H) such as body size, coloration, punctation, the shapes of the head and pronotum. The sexual characters are somewhat variable, too, especially the shapes of the posterior margin of tergite VIII (Figs 3A–C, 3J–K) and sternite VIII (Figs 3D–F, 3M–P) in both sexes, and the shapes of the ventral process and the membranous structures of the aedeagus (Figs 4B–F). Specimens from Yunnan are usually relatively small (BL 4.83–6.04 mm, FL 2.95–3.45 mm), have blackish elytra (Figs 1C–D) sharply bicolorous femora, and partly (16 males and 9 females) a bright red pronotum (Fig. 1B). In the specimen from Guangxi the forebody has a faint blueish hue (Fig. 1E) and the sclerotized spine in the internal sac of the aedeagus is slender (Fig. 4D). All the specimens from Hainan have an on average larger body (BL 5.84–6.95 mm, FL 3.37–3.61 mm), a forebody with a weak or distinct metallic hue (Figs 1F–H), entirely black femora, and conspicuous membranous structures in the internal sac of the aedeagus (Figs 4E–F). In the material from Vietnam and Laos, most of the specimens have a black forebody, some have a more or less distinct blueish or greenish metallic hue, and seven specimens from Vietnam have a reddish pronotum. The legs of all the specimens from Vietnam and Laos are bicoloured, but the extent of the yellowish coloration of the femora is highly variable.

Distribution and natural history

According to Rougemont (1997)[2], Dysanabatium jacobsoni had been recorded from Indonesia (Java), Malaysia, Thailand, Vietnam, and one locality in the south of the Chinese province Yunnan. The currently known distribution is mapped in Fig. 6. The above specimens from Laos represent new country records. The altitudes of the examined material and of the material seen by Rougemont (1997)[2] range from 200 to 1200 m. The specimens from China were found in flood debris, moss, leaf litter and soil near streams in evergreen broad leaved forest, partly together with Dysanabatium hainanense (Fig. 5).
