Chrysis sinuosa Dahlbom, 1854  Plate 21

Chrysis sinuosa  : Dahlbom 1854: 153.

Type locality.

South Africa: "Capitis Bonae Spei".

Holotype ♂.

[Cap. B. Spei] [Mus. Payk.] [Type] [ sinuosa  Dahlbom 84] [NHRS-HEVA000001120].


The type of Chrysis sinuosa  lacks the right flagellum and the right foreleg. Dahlbom (1845: 11-12) described Chrysis sinuata  based on two syntypes, a male and a female, with the same colour "Divis IV. Thorax variegatus. Abdomen cyaneo-. viridi- et aureo-fasciatum". He described the female with four teeth on the anal margin ("Subdivis. 2. Abdominis segmentum 3:tium apice 4-dentatum") (Plate 20D) and the male without teeth on the anal margin, but with a simple undulation ("Subdiv. 3. Abdominis segmentum 3:tium apice undulatum") (Plate 21D). These two specimens clearly belong to two different species-groups. Later, Dahlbom (1854: 153) recognised the male as belonging to a different species and described it with the name Chrysis sinuosa  . He left the female under the name Chrysis sinuata  Dahlbom, 1845, without noticing that this name was already used by Brullé (1833).

Mocsáry (1889: 296), without type examination, considered Chrysis sinuosa  Dahlbom, 1845 and Chrysis sinuata  Dahlbom, 1854 ("ex parte, solum ♂" [the male only]) as synonyms of Chrysis bellula  Guérin-Méneville, 1842. Mocsáry (1889: 440) also replaced the name Chrysis sinuata  Dahlbom, 1845, nec Brullé, 1833 ("ex parte, solum ♀") with Chrysis poecila  Mocsáry, 1889. Chrysis bellula  is now considered endemic to Madagascar, absent from South Africa ( Azevedo et al. 2010: 858). Since Mocsáry (1889: 428) did not examine Dahlbom’s types, he described again Chrysis sinuata  Dahlbom, 1845 as a new species from South Africa with the name Chrysis eximia  Mocsáry, 1889. We examined the type of Chrysis eximia  , which is deposited at the NHMW.

In this case, the replacement name Chrysis poecila  Mocsáry has priority over Chrysis eximia  Mocsáry and therefore we propose the new synonym Chrysis eximia  Mocsáry, 1889 = Chrysis poecila  Mocsáry, 1889. Edney (1952: 423) followed Mocsáry in the interpretation of Chrysis (Holochrysis) bellula  Brullé, but without reporting any differences between the sexes. He also described Chrysis ceres  Edney, 1952, which resulted synonym of Chrysis sinuosa  Dahlbom. Kimsey and Bohart (1991: 463), without the examination of Dahlbom’s types, synonymised Chrysis sinuata  Dahlbom, Chrysis poecila  Mocsáry and Chrysis ceres  Edney with Chrysis sinuosa  and used eximia Mocsáry, 1889 as the valid name. Madl and Rosa (2012) followed the interpretation given by Kimsey and Bohart (1991).

According to the types, the two valid species and their synonymies are:

Chrysis poecila  Mocsáry, 1889 replacement name for Chrysis sinuata  Dahlbom, 1845 nec Brullé, 1833 (synonyms: Chrysis eximia  Mocsáry, 1889; Chrysis westwoodi  Mocsáry, 1912) ( Chrysis splendidula  - senegalensis  group);

Chrysis sinuosa  Dahlbom, 1845 (synonym: Chrysis ceres  Edney, 1954) ( Chrysis capitalis  group).

Current status.

Chrysis sinuosa  Dahlbom, 1854.
