Pseudoscolia maculata Radoszkowski, 1876

( Figs 10–17 )

Pseudoscolia maculata Radoszkowski, 1876: 103 , ♀, ♂. Lectotype, ♀ ( present designation): КИЗИлъкумъ [typewritten, cyrillic] // ♀ // 12. // ♂ // Coll. / Radosz. // Type [red label] // PseudoScolia / maculata ♀ [handwritten by Radoszkowski] // MfN URL http.//coll.mfn-berlin.de/u/394798 [MNHU, photos examined].

Pseudoscolia clavata Kazenas, 1994: 47 , ♀, ♂. Holotype: ♀, Turkmenistan: Kara Kala area in Kopet-Dagh Mountains [ZISP, examined]. Syn. nov.

Material examined. Kyzylkum [ Kazakhstan: Turkistan Region], 1 ♀ [photos of lectotype, MNHU]; Turkmenistan, Kara Kala area in Kopet-Dagh Mountains, 1. V .1991, 2 ♀, 1 ♂ ( holotype and paratypes of Pseudoscolia clavata Kazenas ), V . L. Kazenas [ ZISP]; Turkmenistan, Badkhyz Nature Reserve, 15. V .1976, 1 ♀, A.S. Lelej [ ZISP] .

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.

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).

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 ).
