0380B274D040E513FF11D647B8CFFC8C.taxon	diagnosis	Diagnosis. The female differs from all other Pseudoscolia by a dark quadridentate clypeus (Fig. 15), the male by a clavate apical flagellomerus (Fig. 17). Additional recognition features are: pronotal collar without anterolateral tubercle and median furrow; metapostnotum rugose, posteriorly transversely striate; no deep constriction between metasomal segments; male pronotal collar black.	en	Mokrousov, Mikhail V., Proshchalykin, Maxim Yu., Maharramov, Mahir M.

0380B274D040E513FF11D647B8CFFC8C.taxon	description	Description. See Kazenas 1994: 47 (as P. clavata) and Kazenas 2004 (key on p. 121 and additional description, p. 123) (as P. clavata). Justification of New Synonymy. The female of P. maculata has a unique feature — dark clypeus (the clypeus is light in all other species), as well as P. clavata Kazenas. In addition, quadridentate clypeus, lacking anterolateral tubercle and median furrow on pronotal collar, rugose metapostnotum with transverse striations posteriorly, no deep constriction between metasomal segments and general coloration, allow us to clearly identify the Pseudoscolia clavata Kazenas, 1994, syn. nov. with the Pseudoscolia maculata Radoszkowski, 1876. A study of the photographs provided by Stefanie Krause (MNHU) (Figs 10 – 12) allowed us to synonymize P. clavata, known from the same are with P. maculata (Kyzylkum, see Kazenas 2004: 123).	en	Mokrousov, Mikhail V., Proshchalykin, Maxim Yu., Maharramov, Mahir M.

0380B274D040E513FF11D647B8CFFC8C.taxon	distribution	Distribution. Turkmenistan, Kazakhstan. Record of this species from northeastern Uzbekistan by Medetov et al. (2024) requires verification. Note. According to the labels (Fig. 12), the specimen was collected in Kyzylkum on 12 May 1871 (“ 10 miles west of the Dyusebay well, in the rolling sands ”, see Baker 2004: 248) by the expedition of A. P. Fedtschenko. The lectotype is in poor condition, the upper part of the head, some flagellomeres and legs missing, the metasoma separated (Figs 10, 11).	en	Mokrousov, Mikhail V., Proshchalykin, Maxim Yu., Maharramov, Mahir M.

0380B274D046E511FF11D697BBBFFD30.taxon	diagnosis	Diagnosis. Closely related to Pseudoscolia angelae (Kohl, 1891), P. theryi (Vachal, 1893) and P. splendida Giner Marí, 1945. It differs from P. theryi by: yellow triangular spots at bottom of inner eye margins well developed (absent in P. theryi); male mandible without row of setae (in P. theryi external surface of basal part with row of setae), male forebasitarsus L / H ratio (lateral view) near 2 × (about 3 × in P. theryi). The female differs from these three species by a long ocello-ocular distance (distinctly longer then hind ocellus diameter in P. ferruginea, and not longer in P. angelae, P. theryi and P. splendida). The male differs from P. angelae and P. splendida by the forebasitarsus L / H ratio (lateral view) near 2 × (less than 2 × in P. angelae and P. splendida) as well as antenna shape — F 8 – 10 slightly pointed apicoventrally, F 11 slightly longer than wide (F 8 – 10 pectinate, F 11 L / W ratio near 2 × in P. angelae, F 8 – 10 rounded and F 11 L / W ratio near 1.2 × in P. splendida).	en	Mokrousov, Mikhail V., Proshchalykin, Maxim Yu., Maharramov, Mahir M.

Mesonotal setae ill developed. Mesopleuron densely punctate, with setae about midocellus diameter long. Mesopostnotum shiny, with sparse punctures.

Wings venation typical for the genus. Metasoma without constrictions between segments, terga with fairly dense micropunctation, punctation sparser towards apical segments. Pygidial plate broadly rounded apically, with slightly widened and raised sides; with distinct punctures and microsculpture, matt.
