Comments

A Balkanian species that lives on Chamaecytisus spp. ( Fabaceae Lindl. ) and captured together mostly with H. (H.) leptocerus (Kirschbaum, 1856) and rarely with H. (H.) genistae (Scopoli, 1763) ( Josifov 1958; Kment & Baňař 2012; Kment et al. 2013b). Due to its close resemblance to both species, it was repeatedly overlooked or misidentified in the literature ( Kment & Baňař 2012; Kment et al. 2013b). Males of the newly recorded species can only be reliably distinguished from these two species by the different shape of parameres. However, females can be distinguished by the shape of second antennal segment which is cylindrical in H. leptocerus , cylindrical in the basal ⅓ and strongly inflated in the apical ⅔ in H. cytisi and gradually inflated throughout its whole length in H. genistae ( Fig. 9B ) ( Josifov 1958). Additionally, females of H. cytisi and H. genistae are distinguished by different shapes of squama covering the base of ovipositor ( Kment et al. 2013b).
