Review (by Malcolm Storey)

In German.

We have only two species of the genus (linearis and xanthostoma). A rough translation of Jansen follows:

Antenna segment 4 usually only 2/3 as long as the 3rd or even shorter (Fig. 5b, Fig. 10); Rounded genital plate. xanthostoma
Antenna segment 4 usually 3/4 as long as the 3rd or longer (FIG. 6b, FIG. 10); genital plate ± finished. linearis
Discussion: After a long uncertainty about the status of the two species, H. linearis and H. xanthostoma, STRITT (1941) was able to separate them at least in females following extensive breeding attempts.

In his "Hartigia from Agrimonia" (= H. linearis) the fourth antennal segment is longer in relation to the third than in the "Hartigia from Ulmaria" (= H. xanthostoma). In addition, the spaces between the saw teeth in animals from Agrimonia are flatter (Fig. 4 in STRITT, 1941). Dotting, colour distribution and the interantennal groove was much less useful and KONOW’s (1896) feature of the bending of the third antenna element is completely useless.

The present investigation included animals from different parts of Europe as well as the entire STRITT material to test STRITT’s results on a wider scale. No reliable way to separate the males has been found, but the best criterion (apart from breeding) is the proportion of the antennal segments (Figures 6, 9 and 10) . (This will at least distinguish extreme individuals).
