{Cardiocondyla emeryi}Forel's (1881) description is at {original description}. Emery (1909a: 26) gave a comprehensive illustrated description, this is at {original description}. Arnold (1916) gave a translation and illustrated description, this is at {original description} and {original description}. The small drawing is by Emery from his Myrmicinae catalogue (Emery, 1922f). Karavaiev's (1911) description of mahdii is at {original description}. Bolton's modern description (1982) is at {original description} Seifert's re-description (2003) is at {original description}

Note fezzanensis and monilicornis are not in Seifert's synonyms - he has them as "incertae sedis"; schatzmayri is moved to a junior synonym of Cardiocondyla fajumensis.

Described as a tramp species by Bolton (1982). Wheeler (1922) noted records from Zaïre{unavailable due to copyright}.
From Nigeria, specimens in the CRIN collection had been found in soil at CRIN (B. Bolton). Also collected at Bussa (J.T. Medler).
Bolton (1982) listed Ghana collections at Polcoase (W. Bellfield) and Kibi (D. Leston). Collected by Room (1971) from open ground at the Mamfe-Mampong cocoa farm in Ghana.
In Cameroun collected at Nko'emvon (D.A. Jackson).
Collingwood (1985) reporting it from Saudi Arabia, noted all the samples were taken from leaf litter in tree shade.

Type form - head and alitrunk yellow-ochre, gaster varying to dark brown.


{Cardiocondyla emeryi}Drawn specimen from Nigeria (Taylor, 1979: 3) TL 1.77 mm, HL 0.44, HW 0.36, SL 0.28, PW 0.25; features as for the genus, then as in key. Colour orange and the gaster and antennal club are brown.


{Cardiocondyla emeryi}The photomontage is of a worker from Egypt, Talka Mansurah, collector Mostafa Sharaf.


{Cardiocondyla yorubae vs emeryi}Cardiocondyla yorubae Rigato - name change from yoruba is necessary as "Yoruba" is the name of the human tribe, so the correct name has to become an adjective - yorubae

Described by Rigato (2002) from IITA, north of Ibadan, see - {original description}. However, I can find no significant difference between Rigato's description and that of emeryi; the drawing I made of emeryi from no more than 30 km away matches Rigato's (pedicel dorsum) and other details are as in Rigato's description. Although the drawing is very small, it is apparent that the specimen illustrated in Emery (1922f) also has the same pedicel shape as my drawing and that of Rigato (for yorubae) and it is the Bolton (1982) drawing that may be misleading. Comparing the Rigato drawing and my montage of a specimen from Egypt on the same size scale shows no obvious difference and the Egypt specimen appears to exactly match Rigato's description. The specimen from Ghana, below, also matches the descriptions.
It is curious that Bolton supplied the IITA specimens but did not give Rigato any CRIN specimens (collected by him, Bolton, and identified by him as emeryi). Rigato noted yorubae as having a lesser size TL 1.6-1.7 mm, than emeryi, citing Bolton (1982). Bolton, actually gave TL 1.7-2.1 mm; Forel (1881) gave TL 1.6-1.8 mm; the specimen I drew had TL 1.77 mm and other slightly larger dimensions than yorubae.
Thus, I cannot regard yorubae as anything other than a junior synonym of emeryi. Moreover, it is obvious that the IITA specimens were examined by Seifert, who also listed Bolton specimens from CRIN, like the one I drew. The Rigato drawing shows the angular profile to the petiole, given for the type form by Seifert.


{Cardiocondyla emeryi}The photomontage is of a worker from Ghana, collector S Sky Stephens (06G0021).


Congo Basin form - head and alitrunk red-brown, gaster near black.


{Cardiocondyla emeryi}Workers from Congo, Brazzaville, collectors Yves Braet & Eric Zassi (pitfall t 1.1, t 1.2, t 1.3 & t 1.19)


Cardiocondyla emeryi queenThe photomontage is of a queen from Sudan, Abu Gmein, Blue Nile; collector J Mathews (JM 115)

It is an exact match for my Nigeria drawing, the Congo and Egypt workers (see above) and the mahdii type below.

{Cardiocondyla emeryi}The photomontage is collated from http://www.antweb.org/specimen.do?name=casent0006004 Collection Information: Specimen Code CASENT0006004 Locality Gabon: Ogoove-Maritime: Reserve de la Moukalaba-Dougoua, 7 km NW Doussala; 02°19'50"S 010°32'39"E 110 m; Collection codes: GA00S151; Date: 21 Mar 2000; Collected by: S.V.Noort; Method: sweep; Habitat: Savanna, grasses & Nauclea latifolia

This specimen although from the western side of the continent appears close to the description given by Seifert for C. emeryi rasalamae; i.e the reduced sculpture of the clypeus, the distinctive foveae on the vertex; the reduced sculpturation on the alitrunk (mesosoma) and petiole; and the convex profile of the petiole dorsum.
