This species was described from Forest Reefs in New South Wales and occurs widely in south-eastern Australia. It is also present in New Caledonia, from where it was described as M. caledonicus  . It is shiny black with only a faint vestiture of fine setae, which is diagnostic on ventrites 3 and 4 but also (particularly in comparison with M. servulus  and M. maculatus  , which share the character of contiguous procoxae with M. acaciae  ) on the pronotum and elytra. The penis of M. acaciae  ( Figs. 15–16View FIGURES 14 – 19) is also distinctive, the body being narrower and with an attenuate, narrowly truncate apex and a pair of small, indistinct apical endophallic sclerites and a larger, caliper-like sclerite at the base. 

Lea (1899) originally recorded Acacia decurrens  as a host of M. acaciae  , but his type material of acaciae  includes specimens of both M. acaciae  and M. maculatus  (E. C. Zimmerman, in litt.) and it is evident that this host record applies to M. maculatus  instead. New (1979) reported collecting M. acaciae  from A. dealbata  and New (1983) rearing it from seeds of A. baileyana  , but re-examination of the specimens showed them to be M. maculatus  too, and host specificity tests confirmed that M. acaciae  does not oviposit on A. baileyana  and A. dealbata ( Donnelly, 1992)  . It was first reared from its true main host, A. melanoxylon  , in 1976 by M. van den Berg (van den Berg, 1982), and in 1980 T. Auld reared it from seeds of A. elongata  ( Auld , 1983, 1989). In New Caledonia it was collected (and appears to develop) on A. simplex  (recorded on the labels as A. laurifolia  ), a perennial climber native to the western Pacific region. The species was released against A. melanoxylon  in 1986 in South Africa ( Donnelly , 1992; Dennill et al., 1999), where it established slowly but now controls A. melanoxylon  very successfully ( Dennill et al. 1999; Impson et al., 2011). In our study we collected M. acaciae  from A. glaucocarpa  as well, possibly an additional host ( Tables 1, 2). The single specimen found on A. baileyana  at Kyeamba ( Table 1) is regarded as a concincidental association ( Table 2). A series of five specimens in the ANIC, collected in 1986 by C. Reid at Kioloa in New South Wales on A. longifolia  , and seemingly together with a similar series of M. ventralis  , is not regarded as representing a host record.
