Chaetostomella cylindrica (Robineau-Desvoidy, 1830) aggregation ( fig. 9 )

Material examined. Rif: Marabout Douar Halila (sweeping), 10.06.2018, 1 Ơ, 1 ♀ (El Harym) ; 24.06.2018, 7 Ơ, 2 ♀; 25.06.2018, 7 Ơ, 2 ♀; 27.06.2018, 1 Ơ, 3 ♀; reared from Mantisalca salmantica , 28.06.2018, 2 Ơ; Mkhinak , reared from Ptilostemon rhiphaeus, 22.07.2019, 1 ♀ ; reared from Mantisalca salmantica , 24.07.2019, 1 ♀; Douar Kitane , reared from Cynara cardunculus , 08.02– 02.03.2020, 13 Ơ, 4 ♀ (El Harym).

Host plants. Arctium lappa L., A. tomentosum Mill. , Carduus crispus L., Ca. nutans L., Centaurea bracteata Scop., Ce. cyanus L., Ce. jacea L., Ce. maculosa L., Ce. montana L., Ce. nervosa Willd., Ce. nigra L., Ce. nigrescens Willd., Ce. scabiosa L., Ce. triumfetti All., Cirsium acaule Scop., Ci. arvense (L.) Scop., Ci. eriophorum (L.) Scop., Ci. erisithales (Jacq.) Scop., Ci. heterophyllum (L.) Hill., Ci. oleraceum (L.) Scop., Ci. palustre (L.) Scop., Ci. rivulare (Jacq) All., Ci. tuberosum (L.) All., Ci. vulgare (Ten.) Savi. , Crupina vulgaris Pers. ex. Cass., Cynara cardunculus L., Mantisalca salmantica (L.) Briq. & Cavill., Notobasis syriaca (L.) Cass., Onopordum acanthium L. O. illyricum L., Ptilostemon rhiphaeus (Pau & Font Quer) Greuter., Serratula tinctoria L. ( Hendel, 1927; Merz, 1994; Smith et al., 2009).

Remarks. Actual taxonomic status of populations associated with different host plants is unclear ( V. Korneyev, unpublished data). Some of the Mediterranean and Middle East populations have been described as separate species (see also: Knio et al. (2007) and Smith et al. (2009) for discussion), but this aggregation of cryptic species, subspecies or host races needs a full taxonomic revision involving more host-plant, morphometric, and genetic evidence.

In this study, C. cylindrica was reared from Mantisalca salmantica (L.) Briq. & Cavill. (fig. 12, d) (new host plant) and also from Cynara scolymus L. Here, we consider C. cylindrica as an unrevised aggregation of host races or cryptic species.

Distribution. Most of Europe ( Merz & Korneyev, 2004), North Africa ( Algeria, Tunisia) ( Heřman & Dirlbek, 2006), Morocco (first record of genus and species); Iran ( Khaghaninia et al., 2012; Mohamadzade Namin & Korneyev, 2016), Jordan, Kazakhstan, Turkey, Lebanon & Afghanistan; China.
