Several semi-analytic models (SAMs) try to explain how galaxies form, evolveand interact inside the dark matter large-scale structure. These SAMs can betested by comparing their predictions for galaxy-galaxy-galaxy-lensing (G3L),which is weak gravitational lensing around galaxy pairs, with observations. Weevaluate the SAMs by Henriques et al. (2015; H15) and by Lagos et al. (2012;L12), implemented in the Millennium Run, by comparing their predictions for G3Lto observations at smaller scales than previous studies and also for pairs oflens galaxies from different populations. We compare the G3L signal predictedby the SAMs to measurements in the overlap of the Galaxy And Mass Assemblysurvey (GAMA), the Kilo-Degree Survey (KiDS), and the VISTA Kilo-degreeInfrared Galaxy survey (VIKING), splitting lens galaxies into two colour andfive stellar-mass samples. Using an improved G3L estimator, we measure thethree-point correlation of the matter distribution for mixed lens pairs withgalaxies from different samples, and unmixed lens pairs with galaxies from thesame sample. Predictions by the H15 SAM agree with the observations for allcolour-selected and all but one stellar-mass-selected sample with 95%confidence. Deviations occur for lenses with stellar masses below$9.5h^{-2}\mathrm{M}_\odot$ at scales below $0.2h^{-1}\mathrm{Mpc}$.Predictions by the L12 SAM for stellar-mass selected samples and red galaxiesare significantly higher than observed, while the predicted signal for bluegalaxy pairs is too low. The L12 SAM predicts more pairs of small stellar-massand red galaxies than the H15 SAM and the observations, as well as fewer pairsof blue galaxies. Likely explanations are different treatments of environmentaleffects by the SAMs and different models of the initial mass function. Weconclude that G3L provides a stringent test for models of galaxy formation andevolution.
