Chrysis lateralis Dahlbom, 1845  Plate 10

Chrysis lateralis  : Dahlbom 1845: 10.

Type locality.

Greece: Rhodes.

Syntype 1 ♀.

[Rhodus] [Hedenb.] [NHRS-HEVA000001095].


This species belongs to the Chrysis elegans  group and is conspecific with Chrysis separata  Trautmann, 1926. None of the most important authors ( Dahlbom 1854; Mocsáry 1889; du Buysson (in André) 1891-1896; Trautmann 1927; Berland and Bernard 1938; Linsenmaier 1951, 1959, 1968) mentioned this species. Only Dalla Torre (1892: 74) and later Kimsey and Bohart (1991: 431) listed it as a valid species in the comparata  - scutellaris  group, without type examination. The female syntype has all the typical characteristics of Chrysis separata  , species widespread from Zante (typical locality) to Middle East. A second syntype is housed in the Dahlbom collection in MZLU. We here propose Chrysis separata  Trautmann, 1926, as a new synonym of Chrysis lateralis  Dahlbom, 1845.

A similar case was found studying Dahlbom’s type of Chrysis confluens  (Dahlbom, 1845). Chrysis confluens  was described from Rhodes and belongs to the Chrysis elegans  group. Chrysis confluens  was synonymised by Dahlbom himself ( 1854: 159, var. h) with Chrysis elegans  Lepeletier, 1806 and remained in synonymy with Chrysis elegans  in all the most important works. However, nobody noticed that the description was perfectly matching the description of Chrysis elegans var. smaragdula  Trautmann, 1926 nec Fabricius, 1775, also described from Rhodes. Linsenmaier (1959: 137) replaced the name Chrysis elegans smaragdula  Trautmann with Chrysis interrogata  Linsenmaier, 1959 without taking care of the possible synonymy with Chrysis confluens  (Dahlbom). There is no doubt about Chrysis elegans var. smaragdula  Trautmann, 1926 (currently Chrysis elegans ssp. interrogata  Linsenmaier) as a new synonym of Chrysis confluens  (Dahlbom, 1845), because Chrysis confluens  is one of the most common species on the island and its peculiar colour is unique in this species group: "Corpus æneo- aut subaurato-viride" and "Caput et thorax cyaneo- et viridi-variegata. Abdom. segmenti 3:tii series punctorum ante apicalis numerosorum orbiculatorum subconfluentium. Corpus 2 ½ lin. long.". This peculiar green or golden-green colouration is well emphasized by the name smaragdula, which in Latin means emerald green.

Both names Chrysis separata  and Chrysis interrogata  have been used mainly by Linsenmaier and a few other authors (i.e. Rosa 2005b; Strumia and Yildirim 2009), and according to the ICZN there is no reason for applying the Reversal of Precedence. The type of Chrysis confluens  is housed in the Dahlbom collection in MZLU.
