Remarks. According to the most recent revision of the Chinese species of this genus ( Miroshnikov & Lin 2017), A. serricornis is distributed in China (Xinjiang and Inner Mongolia; however, the authors also reported on the two problematic males that are known from one of the southernmost provinces— Guangdong), Mongolia (mainly southern part of the country) and SE Kazakhstan.

This highly variable species has been already described several times based on its different forms ( A. tomentosa (Gebler, 1845) ; A. obtusicollis (Motschulsky, 1860) ; A. mongolica Semenov, 1901 ; A. kadyrbekovi Kadlec, 2006 ) ( Danilevsky 2008; Miroshnikov & Lin 2017). It also shows a strong sexual dimorphism, which causes additional difficulties in its systematics.

Apatophysis serricornis , unlike some other representatives of the genus, is most likely a nocturnal species (at least two specimens have been recorded as attracted to a light trap by Namhaidorzh (1972)) and its bionomy remains largely unknown. According to Danilevsky (2008), it is ecologically associated with desert and semi-desert habitats of different types (both sandy and clay soils). Larvae develop in roots of probably different desert shrubs and trees, however, development only in Haloxylon Bunge (Amaranthaceae) was confirmed ( Danilevsky 1988). Adults are active from June to August ( Danilevsky 2008).

We have not collected any individual of this species despite the frequent use of light traps in the region of its occurrence. This is probably explained by the fact that our research was conducted in a rather late season, in the last quarter of July. Most of the Mongolian records relate to the second half of June. The depicted female comes from the Kaszab’s material ( HNHM), and it was collected in southern Mongolia (Ömnögovi aimag) .
