A syntype slide listed below has 32 adults with 28 females and 4 males and three pupae, many of which are damaged and dark. However, some distinguishing characters can be seen as follows: antennal segments short, III no more than 2.5 times as long as wide, III clear yellow, IV–V light brown with yellow at base, VI largely brown with extreme base yellow, VII–VIII brown ( Fig. 40 ); postocular setae as long as or a little longer than eyes, slightly blunt at apex ( Fig. 18 ), rarely shorter than eyes; maxillary stylets retracted to postocular setae, close together medially in head, their separation 0.05–0.1 of head width ( Fig. 18 ); metanotum with sculpture of complete and dense longitudinal stripes medially, and narrowly reticulate at anterior angles ( Fig. 85 ); all tarsi yellow, fore tibiae yellow but shaded sub-basally, mid and hind tibiae yellow on distal fifth or more; fore wings shaded brown with dark median longitudinal line; anal setae as long as tube. Specimens on a slide from USA and some slides from Australia in ANIC labelled as L. vaneeckei show variation in sculpture on the metanotum and also with regard to the length of the anal setae. This species is usually found under the scales of cultivated lily bulbs. It was originally described from the Netherlands, but is recorded from Japan, New Zealand, Australia, and China and might be widespread in the Holarctic ( Okajima 2006; Mound et al. 2023; Han 1997a). The type specimens of the following species have been checked, L. sinarundinariae Han , L. chinensis Han , L. sanxiaensis Han and L. diwasabiae Han. No significant differences could be seen between these and the available specimens of L. vaneeckei , and all four are here considered as new synonyms of that species.
