( Figs 13B, 13D View FIGURE 13 )

Chrysis anisitsii Brèthes, 1906: 9 . Lectotype ♀ designated by Bohart in Kimsey & Bohart (1991: 511). Paraguay: Distrito Capital: Asunción, Anisits (MACN).

Chrysis (Hexachrysis) anisitsi Bischoff, 1910: 486 nec Brèthes, 1906. Lectotype ♀, designated by Bohart in Kimsey & Bohart (1991: 511). Paraguay: Distrito Capital: Asunción, Anisits (ZMB, examined). Synonyms of Chrysis obidensis Ducke, 1903 according to Kimsey & Bohart (1911: 511); Lucena et al. (2016, 2024: 42).

Chrysis anisitsii : present paper: stat. resurr.

Material examined. Lectotype ♀ of Chrysis (Hexachrysis) anisitsi Bischoff : Asuncion, Paraguay, J.D. Anisits / Asunc. n°130 / Chrysis anisitsii / Chr. anisitzi Brèthes Bisch. <handwritten by Bischoff> / Type / Zool. Mus. Berlin.

The only specimen in the collection at ZMB lacks lectotype labels by Bohart, but is undoubtedly a syntype from the original description, based on locality labels and identification labels attributed to Bischoff. Considering the type locality and the handwritten labels “ Chrysis anisitsii ” <probably handwritten by Brèthes> and “ Chr. anisitzi [!] Brèthes Bisch” <handwritten by Bischoff>, it is plausible that the specimens studied by Bischoff (1910) were part of the same type series examined by Brèthes (1906). The specimen housed at ZMB perfectly matches the description provided by Brèthes (1906). It is highly likely that Bischoff (1910) studied specimens, at least a male and a female, sent by Friese, Anisits or Schrottky to the ZMB along with other Hymenoptera , as in the case of the holotype of Centris anisitsi ( Schrottky, 1908) ( Vivallo 2020) . Presumably unaware of Brèthes (1906), Bischoff (1910) described this species as new under the name anisitsi , although he was obviously aware that the name, although differently spelled on the labels, originated from Brèthes, there is no mention of that in the description.

Both Chrysis anisitsii Brèthes and Chr. anisitsi Bischoff View in CoL were synonymized with Ipsiura obidensis ( Ducke, 1903) by Kimsey & Bohart (1991), but some diagnostic differences can be observed. Specifically, apart from differences in colour patterns ( Figs 13A, B View FIGURE 13 ), the shape of the black spots on the second sternum is subsquare in I. obidensis ( Fig. 13C View FIGURE 13 ) and subtrapezoidal in I. anisitsii ( Fig. 13D View FIGURE 13 ). For these reasons, we resurrect Ipsiura anisitsii ( Brèthes, 1906) stat. resurr. and consider I. anisitsi ( Bischoff, 1910) View in CoL as its synonym, in agreement with Kimsey & Bohart (1991); according to Code Art. 58.14 I. anisitsi (Bischoff) View in CoL is also a variant spelling of I. anisitsii (Brèthes) , the two names deemed to be identical and therefore homonyms.
