Macropsis arslanbobica Dlabola, 1967: 31. Syn. n.
Description. Body green, forewings usually more or less darkened, especially in apical part, in males darker than in females (Figs. 2–7). In darkest males, forewings almost black with widely lightened costal margin (Fig. 2). In light-coloured specimens forewings entirely translucent with green veins (Figs. 4, 7). Proportion of specimens with dark forewings varies greatly between different localities.
Apodemes of 2nd abdominal sternite of males more or less triangular, with distinct projections at base on inner margins (Figs. 14, 20–24). Tergal apodemes rather short and rounded (Figs. 18–19).
Pygofer processes almost straight, with tips slightly bent forward (Figs. 15, 25–26). Penis in side view comparatively short and broad (Figs. 16, 27–29). Style tips pointed and somewhat bent inwards (Figs. 17, 30–33). 2nd valvulae of ovipositor with 3–5 preapical teeth (Figs. 34–36).
Body length (including tegmina): ♂, 3.4–3.9 mm; ♀, 4.1–4.5 mm.
Nymph either entirely black (Fig. 8) or bright green (Fig. 9); nymphs with intermediate coloration (as in adult specimens, Figs. 3, 6) were not found.
Differs from M. ibragimovi and M. asiatica by well-developed projections at base of apodemes of 2nd abdominal sternite in male and, usually, by presence of males with very dark forewings in populations. Very similar to M. tarbagataica, but can be distinguished from latter one by broader penis and somewhat smaller body size.
Host. Salix niedzwieckii (section Helix).
Calling signal. Signal consists of repeated phrases following one after another without gaps (Figs. 37–50). Each phrase begins with trill sounding like monotonous buzz, followed by succession of pulses; pulses at end of succession sometimes merge together. Durations of each part as well as of whole phrase vary greatly. Males usually sing unceasingly for several minutes.

Holotype of M. arslanbobica with the labels: “ Kazachstan [sic!] Dubovskij Arslanbob 10. VII. 60 ” (Fig. 10), “ Macrosteles [sic!] arslanbobica n. sp. TYPUS det. Dlabola” (Fig. 11), “Museum Paris collection Dlabola” and “Museum Paris MNHN (EH) 7493”.
Distribution. West Tien Shan Mts.: foothills and midlands of Chatkal and Ferghana Mtn. Ranges (Kyrgyzstan). The range of host plant includes West and Central Tien Shan Mts. and also Alai and Transalai Ranges of the Pamir-Alai Mts. System.
Remarks. Identification of M. abdullaevi is based on the original description and investigation of specimens from several localities in the West Tien Shan Mts. including the type locality, Arslanbob Town on the Ferghana Mtn. Range. Two key characters mentioned in the original description (Dubovskiy, 1966) are an aid in properly identifying this species. These are the unusually dark forewings and the host plant, so-called “small-leaved willow” (Dubovskiy, 1966): S. niedzwieckii actually differs from all other willows from this region by its small leaves about 25–50 mm in length.
Identification of M. arslanbobica is based on reinvestigation of the holotype collected at the same locality as M. abdullaevi. This is a male specimen 3.9 mm in length with underdeveloped 2nd abdominal apodemes (Figs. 14– 17). The distinct projection at the base of the left sternal apodeme (Fig. 14) in combination with the rather short and wide penis (Fig. 16) is evidence that it is conspecific with M. abdullaevi. The labels under the holotype contain two errors. First, Arslanbob Town is located on the territory of Kyrgyzstan, not in Kazakhstan. Second, the name “ Macropsis arslanbobica ” is erroneously written as “ Macrosteles arslanbobica ”.
The original description of M. arslanbobica was also somewhat inaccurate (Dlabola, 1967). According to the first line of the description, the male body length is 3.6–4.05 mm, whereas the female was unknown. However, as indicated below, the type material includes only one male (holotype), but seven females.
