Calycomyza artemisiae (Kaltenbach)

( Figs. 53–57 , 383–387 )

Material examined: Ukraine: Transcarpathia: Nova Stuzhytsa, Uzhanskyi National Park, 49°02’N, 22°34’E, 26.vii.2019, Yu. Guglya, ex Eupatorium cannabinum (2♀); “Skalka”, near Uzhhorod, 48°41’N, 22°24’E, 20.ix.2016, Yu. Guglya, ex Eupatorium cannabinum (1 puparium); Sumy Region: Vakalivshchina, 51°02’N, 34°55’E, 1.viii.2013, Yu. Guglya, ex Artemisia sp. (1♂); Kharkiv Region: near Petrivske, 49°10’N, 36°58’E, 16.vi.2019, Yu. Guglya, ex Artemisia vulgaris (2 puparia); same locality, 15, 16.vii.2020, Yu. Guglya, ex Artemisia vulgaris (2♀); same locality, 20.vii.2020, Yu. Guglya, ex Artemisia vulgaris (1♂).

Hosts. Asteraceae : Ageratina Spach , Artemisia L., Eupatorium L. ( Benavent-Corai et al. 2005), Achillea L., Chromolaena DC. ( Warrington 2021) .

Mine. ( Figs. 53, 54 ) The solitary larva develops in a white blotch blister mine. Pupation takes place outside the mine in the soil.

Puparium. ( Figs. 55–57 ) Brownish-orange, semi-glossy, 2.3 mm long, with deep segmentation; finely wrinkled except for wide spine bands. Posterior spiracles set on stout conical protuberances entirely joining towards their bases; with three hook-like sessile bulbs set in a circular configuration at acute angles to each other. Anal plate protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly. Two long, conical, black appendages, thickly covered with spines, developed on the sides of the anal plate viewed from the side.

Cephalopharyngeal skeleton. ( Fig. 383 ) Right mouthhook much larger than the left, each rounded ventrally and bearing two accessory teeth. Intermediate sclerite narrow and long, with long, sharp finger-like process directed ventro-posteriorly; sclerite 2.52× as long as maximum height of left mouthhook. The pharyngeal sclerite bears a large drop-like “closed” window anteriorly. The mouthhook, most of the intermediate sclerite and anterior portion of the pharyngeal sclerite around the “closed” window are strongly sclerotized; the intermediate sclerite dorso-posteriorly and the dorsal and ventral cornua are much less so. Indentation index 77. See also in Sasakawa (1961: Fig. 61 l ).

Female head. ( Figs. 384, 385 ) Bright yellow, with antenna, palpus, oc tr medially and postgena black; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule low, semicircular, not reaching the level of the anterior fr s; pped of medium size, slightly longer than high, with long yellowish pubescence; gena medially 0.24× as high as maximum height of eye.

Female genitalia. ( Figs. 386, 387 ) Proctiger relatively narrow, 3× as long as the maximum width; cylindrical in posterior half and dramatically narrowing anteriorly. Surface of proctiger covered with sparse fine spines. Posterior margin of proctiger slightly concave medially, with bevelled corners laterally; cercus relatively wide, oval and sometimes folded apically. Spermathecae equal in size, dark brown, spherical, sometimes invaginated laterally; without basal collar. Spermathecal duct finely corrugated and weakly sclerotized.

Distribution. Widespread species known from about 20 European countries ( Papp & Černý 2017). Ukraine (first record).
