The lace bug genus Eritingis Drake and Ruhoff, 1962 is widely distributed in the Australian and Oriental Regions, whereas only a single species, E. recentis (Drake and Poor, 1937), has been recorded from the Oriental Region. To date, E. recentis is known to occur in Indonesia, Malaysia, Papua New Guinea, Singapore and Vietnam, but has not been recorded from Japan and Thailand.
Eritingis and E. recentis are recorded from Japan and Thailand for the first time.

The lace bug genus Eritingis Drake and Ruhoff, 1962 (Hemiptera: Heteroptera: Tingidae) comprises 11 species from the Australian and Oriental Regions: E. agyiates Drake and Ruhoff, 1962, E. amoena Drake and Ruhoff, 1962, E. aporema Drake and Ruhoff, 1962, E. exalla Drake, 1961, E. hylaea Drake and Ruhoff, 1962, E. koebeli (Drake, 1944), E. nostratis (Drake, 1944), E. pacifica (Kirkaldy, 1908), E. recentis (Drake and Poor, 1937), E. trivirgata (Horváth, 1925) and E. violina Drake and Ruhoff, 1962 (
Recently, I observed a collection of Tingidae from eastern Asia and found an undetermined species of Eritingis in Japan and Thailand. After careful morphological examination, I concluded that this undetermined species represents E. recentis. In this study, I recorded E. recentis for the first time from Japan and Thailand.
Dried specimens were used. Morphological characteristics of each specimen were observed under a stereomicroscope (SZ60, Olympus, Tokyo, Japan). Specimens were photographed using a digital microscope (Dino-Lite Premier M, Opto Science, Tokyo, Japan). Distribution records of species were mapped using SimpleMappr (

Eritingis recentis can be distinguished from other species of Eritingis based on a combination of the following characteristics: body length 3.0–3.2 mm, 3.3 times as long as maximum width across hemelytra (Fig.

The discovery of Eritingis recentis from Japan represents the northernmost distributional record of Eritingis species.
Adults have been collected in almost all seasons (
The above recorded specimens match well with the photographs of the holotype (
Eritingis recentis is highly similar to E. agyiates in general appearance. The latter is distinguished from the former by the body length 2.7 mm and the rostrum reaching the anterior margin of mesosternum.
