Discussion. Li & Liu (2007) transferred Heterochlorillus nathaliae Josifov, 1974 to Leucodellus with a note that the generic assignment of this species remains doubtful. Indeed, nathaliae is similar to other species of Leucodellus in the color pattern of dorsum and legs, size, body proportions, presence of the gonopore sclerite, and claw shape but strongly differs from congeners in all other respects. The vesica of nathaliae is twice smaller and not coiled, typically S-shaped, devoid of characteristic closely approximating ridges of lateral stripe, and terminating with a single straight and comparatively short blade ( Fig. 18 ). The male genital segment in nathaliae is relatively small, about 0.4 of abdomen, and the sclerotized rings of the dorsal labiate plate are ovoid, of typical Phylini shape ( Fig. 21 ). This species further differs from Leucodellus spp. in having relatively long, scarce, dark semierect setae on dorsum in addition to pale ones.

The vesica of nathaliae is most similar to that of many Compsidolon spp. ( Figs. 19–20 ) in the relatively small size, overall shape and way of twisting of the single strap, form of the single blade and subapical location of the secondary gonopore equipped with well developed gonopore sclerite. The latter feature is documented for Leucodellus spp. ( Figs. 12–17 ), and several otherwise clearly not related phyline genera, viz. Atractotomus Fieber, 1858 ( Stonedahl 1990) , Megalopsallus Knight, 1927 ( Schuh, 2000) , and Chlamydatus Curtis, 1833 ( Schuh & Schwartz 2005) .

Characters of external morphology, including head shape, body proportions, coloration, vestiture composed of two types of setae, and structure of pretarsus are in accordance with the generic placement of nathaliae within Compsidolon . Based on these observations I am proposing Compsidolon nathaliae ( Josifov, 1974) comb. n.
