Cataulacus huberi AndrÉ, 1890; CASENT0915358 (wrongly labelled “ C. mocquerysi ”). A medium-sized ant, TL 5.5-7.8 mm. First report from Tanzania; almost all prior reports are from West Africa and the Congo Basin, with one from Uganda. Single specimen found on H. lucens (Tree 3/50).
Cataulacus intrudens (F. Smith, 1876) ; type queen CASENT0919586; worker of junior synonym baumi, CASENT0904882. A medium-sized ant, TL 4.3-5.1 mm. Widespread in Eastern Africa, from Somalia south to South Africa; this appears to match a described Tanzania variant of a “very variable species”. Listed from Mkomazi by ROBERTSON (1999). Five findings; two on L. schweinfurthi (Trees 3/66 & 3/67); two on V. nilotica (Trees 5/55 & 5/63); and, one on Grewia sp (Tree 2/15); in low numbers.
Cataulacus kenyensis Santschi, 1935 ; CASENT0912560; type collection from Nairobi, Kenya. A small ant, TL 3.6 mm. First record from Tanzania, Four findings; three on V. zanzibarica (Trees 5/17, 5/26 & 5/28), one with many specimens; one on V. nilotica (Tree 5/63), single specimen; generally about 75% size of type but morphologically and proportionately identical. Specimens include a queen and a male, probably the first records of sexuals.
Crematogaster (Cr.) acaciae Forel, 1892 ; CASENT0908494. A small ant, TL 3-5 mm. Widespread but apparently uncommon in Eastern Africa, from Somalia south to South Africa; first report from Tanzania. Single finding, 2 specimens, on H. lucens (Tree 3/50).
Crematogaster (Cr.) foraminiceps Santschi, 1913 ; CASENT0904515. Type location Kenya from where only reports. A small ant, TL 2.2-3 mm. First report from Tanzania. Two findings; one on C. molle (Tree 2/18), 2 specimens; one on L. schweinfurthii (Tree 3/67) numerous specimens. Crematogaster (Cr.) mimosae Santschi, 1914 ; CASENT0904507. Type location Kenya, lower Mount Kenya in galls of V. stenocarpa . A fairly small ant, TL 3.5-4.5 mm. First report from Tanzania, also known from Somalia and Ethiopia. Six findings; five as a dominant on V. zanzibarica (Trees 5/16, 5/17, 5/26, 5/27 & 5/28); one of two specimens on O. holstii (Tree 3/56).
Crematogaster (Cr.) nigriceps Emery, 1897 ; CASENT0904510. Type location Somalia, from V. spines. A fairly small ant, TL 3-3.5 mm. Several reports from Tanzania north to Ethiopia. ROBERTSON (1999) reported it from Mkomazi woodland, as Cr. prelli . Four findings, all as a dominant on V. drepanolobium (Trees 5/58, 5/59, 5/60 & 5/61).
Crematogaster (Cr.) rauana Forel, 1907 , new status; CASENT0908528. Type location Tanzania; near Moshi, sole prior report as a variety of Cr. gallicola . A small ant, TL 2.7-3.0 mm. Single specimen found on H. lucens (Tree 3/51). This is identical in all ways to the type but at the lowest end of the size range given by Forel, 2.7-3.0 mm. Cr. gallicola Forel, CASENT 0908527, is smaller, much less sculptured and has a more rectangular head in full face view.
Crematogaster (Cr.) sjostedti Mayr, 1907 ; syntype CASENT0902105; type location Tanzania, Usambara. A fairly small ant, TL 3.0- 5.5 mm. Widespread in Eastern Africa, from Somalia south to South Africa. Three findings, probably as a dominant; two on C. molle (Trees 2/25 & 2/31); one on T. brownii (Tree 3/68).
Crematogaster (Cr.) tenuipilis Santschi, 1937 , new status; CASENT0912705; type location Kenya, sole finding. A small ant, TL 3-5.5 mm. First report from Tanzania. Two findings on H. lucens (Trees 3/50 & 3/51); one specimen on each. Close to Cr. mimosae in size and form but with distinctive bicloured appearance.
Crematogaster (Cr.) tricolor Gerstäcker, 1859 , revived status; CASENT0104590; type location Mozambique. Readily separable from the unicoloured Cr. castanea F. Smith, 1858 , from South Africa, CASENT0102953.A fairly small ant, TL 4.2-4.8 mm. Widespread in Eastern Africa, from Somalia south to Mozambique; Tanzanian forms include bruta ( Crematogaster (Acrocoelia) castanea Sm. st. bruta Sants. var. tanganikana n. var., Santschi, 1926), CASENT0912649. Two findings; one as a possible dominant on L. schweinfurthii (Tree 3/66); one of 25 specimens on Grewia sp (Tree 2/15).
Crematogaster (Decacrema) solenopsides Emery, 1899 ; CASENT0904483. Type location Tanzania, subspecies flavida ( Crematogaster solenopsides subsp. flavida Mayr, 1907 ) type location Usambara in acacia galls.A small ant,TL 2.25 mm.Four findings;three of 4- 49specimens on V. nilotica (Tree 5/55, 5/56 & 5/57); one of a single specimen on C. molle (Tree 3/65). Crematogaster (Sphaerocrema) amita Forel, 1913 ; CASENT0902063. Type location Mozambique. A fairly small ant, TL 3.4-3.5 mm. First report from Tanzania. Two findings, both on C. molle (Trees 3/64 & 3/65), 4 & 2 specimens.
Crematogaster (Sphaerocrema) kneri Mayr, 1862 ; CASENT0919670. Type location Ghana, scattered reports from across sub-Saharan Africa. A fairly small ant, TL 4.2-4.8 mm. First report from Tanzania. Three findings; one on V. nilotica (Tree 5/55), 2 specimens; two on C. molle (Trees 2/26 & 2/27) ca 25 specimens on each.
Monomorium pallidipes Forel, 1910 ; CASENT0908702.A minute ant, TL 1.5 mm. Type location Eritrea, other reports from Sudan, Kenya and Tanzania (Kilimanjaro, illiustrated, Santschi, 1926). Four findings; three on V. nilotica ( Trees 5/55, 5/63 & 5/64 - 11 specimens); one on Grewia sp (Tree 2/15); one specimen each. Note: the type specimen in the Antweb images is quite a pale yellow. BOLTON (1987) referring only to three specimens from the type collection, had the colour as “uniform medium to dark brown”. Our specimens all are a shiny, dark brown.
Monomorium speluncarum Santschi, 1914 ; CASENT0913855. Holotype & 2 other workers known only from a single site in Kenya. A minute ant, TL 1.5 mm. First record from Tanzania; single finding of four specimens on H. lucens (Tree 3/50).
Tetramorium caldarium (Roger, 1857) ; CASENT0102333; type location Germany. A small ant, TL 2.1-2.4 mm. First report from Tanzania; a tramp species with African records including Kenya. Three findings; two on V. nilotica (Trees 5/56 & 5/63); and one on H. lucens (Tree 3/50). These match the type form of a variable species.
Nesomyrmex latinodis (Mayr, 1895) , revived status; CASENT0914925; type location Mozambique. A small ant, TL 3.1-3.8 mm. Widespread sub-Saharan form that seems to have been wrongly lumped with the Egypt /North Africa type Nesomyrmex angulatus (Mayr, 1862, CASENT0914922) by BOLTON (1982). N. latinodis has a wider postpetiole and slightly longer scapes; also, more sharply angled anterior pronotal corners. N. angulatus specimens appear to have consistently distinctive dark apical segments to the funiculi. Ten findings; five on V. nilotica (Trees 5/55, 5/56, 5/57, 5/63 & 5/64), two on C. molle (Trees 2/18 & 2/31); two on L. schweinfurthii (Trees 3/66 & 3/67); and, one on T. brownii (Tree 3/68). Tetramorium candidum Bolton. 1980; CASTYPE13387. Type location in eastern DRCongo, Bukavu; sole reported finding. A small ant, TL 3.1-3.3 mm. First report from Tanzania. Single finding of one specimen on H. lucens (Tree 3/50).
