Zettel, H. & Pangantihon, C. V., 2020, A NEW SPECIES OF THE TIMASIUS LIVENS SPECIES GROUP (HEMIPTERA: HETEROPTERA: HEBRIDAE) FROM CAMBODIA AND VIETNAM, Far Eastern Entomologist 405, pp. 8-14 : 9-10

The Timasius livens species group

DIAGNOSIS. Dorsal integument usually black (in all described species). Base of forewing with bluish or grayish frosted areas, without white spots. Entire dorsal surface without erect setae; short, thick, appressed setae with metallic shimmer present on head, thoracic nota, and bases of forewings. Buccula with two circular or slightly ovate impressions, posteriorly with two processes, the dorsal one short and acute, the ventral one variable in shape. Metanotal elevation short ( Fig. 1 ); its free apex (in lateral aspect) short. Legs without spines. Genitalia of males small: pygophore in some species with dorsolateral apodemes covering entire paramere or only its base; proctiger often with groups of stout setae; parameres in most species with dorsal teeth, but always without apical hook, usually slightly asymmetrical.

SPECIES INCLUDED. This clade contains only five described species from Pakistan,

north-western India, Nepal, Myanmar, and Thailand (Andersen, 1981; Zettel, 2011, 2012).

However, it is in fact very diverse, especially in Southeast Asia.
