Description
TABLE 1. Differences between Nalassus magomedrasuli sp. n. and N. kalashiani.
| N. magomedrasuli sp. n. | N. kalashiani |
|---|---|
| Morphological structures | |
| Eyes less convex. Ratio of distance at widest part of head to distance between eyes 1.36–1.37 (Figs 2A, B) | Eyes more convex. Ratio of distance at widest part of head to distance between eyes 1.43 (Figs 2D, E) |
| Sexual dimorphism in the structure of apical maxillary palpomere (much wider in male) (Figs 2A, B) | No sexual dimorphism in the structure of apical maxillary palpomere (wide in male and female) (Figs 1D, E) |
| Male antennomeres 2–7 less thickened (Fig. 1F) | Male antennomeres 2–7 more thickened (Fig. 1G) |
| Pronotum widest slightly behind middle | Pronotum widest at basal third |
| Disc of pronotum slightly narrowly flattened along lateral margins (Figs 2A, B) | Disc of pronotum evenly convex (Figs 2D, E) |
| Male pro- and mesotarsi slightly widened, with comparatively short yellowish hairs on lateral margins and ventral side (Figs 3C, D) | Male pro- and mesotarsi little wider, with very dense and long pubescence on lateral margins and ventral side (Figs 3G, H) |
| Male tibiae much thinner (Fig 1A) | Male tibiae wider, robust (Fig. 1D) |
| Scutellar shield with several very sparse punctures or without puncturation (Figs 2A, B) | Scutellar shield densely and finely punctured (Figs 2D, E) |
| Male elytral interstriae finely and sparsely punctured (Fig. 2C) | Male elytral interstriae with slightly coarser and denser puncturation (Fig. 2F) |
| Male abdomen only with one hair brush on ventrite 1 (Fig. 3A) | Male abdomen with two hair brushes: larger on ventrite 1 and smaller on ventrite 2 (Fig. 3B) |
| First abdominal ventrite with much coarser puncturation than on other surface; metacoxal process of abdominal ventrite 1 with much sparser puncturation in apical part (Fig. 3E) | First abdominal ventrite with the same puncture size as on other surface and together with metacoxal process much denser and finer (in in comparative species) punctured (Fig. 3F) |
| Habitats | |
| Limestone montaine steppes with phryganoid vegetation (1100–1500 m) (Fig. 4E) | Alpine meadows et least in Ingushetia (2100–2200 m) (Fig. 4F) |
