Golunda
Division. Reviewed and compared with
Hadromys
and
Mylomys
by
Musser (1987
b
)
, who noted that its dental similarity with the latter, and
Pelomys
, was probably convergent. Analyses of mtDNA gene sequences (cytochrome
b
, 12S and 16S rRNA fragments) are ambiguous in ascertaining the phylogenetic affinity of
Golunda
except to clearly refute the hypothesis presented by some (e. g.,
Jacobs, 1978
;
Misonne, 1969
) that it and
Mylomys
are closely related and derived from a
Pelomys
like ancestor (
Ducroz et al., 2001
). As
Ducroz et al. (2001:198)
noted, "Further studies including a larger sample of African murine taxa will be necessary to evaluate the precise place of this genus." Recent analysis of nuclear
IRBP
gene sequences divorces
Golunda
from alliances with any of the sampled African genera, especially arvicanthines (
Lecompte, 2003
). We isolate
Golunda
in its own division until its relationship to other murines is better understood; molecular comparisons with living Asian
Hadromys
would be especially illuminating. Furthermore, three hypotheses derived from fossil samples have been proposed and require testing. First,
Golunda
originated in Africa and migrated to Asia in late Pliocene (
Jacobs, 1978
;
Patnaik, 2001
). Second,
Golunda
is one of the lineages evolving out of an African arvicanthine group that migrated to Asia during early Pliocene (Cheema, et al., 2003). Finally,
Golunda
evolved from late Miocene Asian
Parapelomys
(
Patnaik, 1997
)
, which in turn was derived from the earlier Asian
Karnimata
(
Jacobs, 1978
;
Jacobs and Downs, 1994
;
Karnimata
=
Progonomys
, according to
Mein et al., 1993
), pointing to
Golunda
as not only an Asian endemic but derived from an endemic Miocene Asian fauna. Pliocene fragments identified as a species of
Golunda
have been recorded from
Ethiopia
, but
Musser (1987
b
)
explained why they do not represent this genus. All current information about evolutionary history of
Golunda
substantiates its endemism to the Indian subcontinent. Enamel microstructure of incisors and molars and its significance documented by
Patnaik (2002)
. Isolated molars from Siwalik strata document
Golunda
’s presence back to the early Pliocene of NW
India
(
G. tatroticus
) and middle Pliocene-early Pleistocene of NW
India
