Nine species are known in the genus Microcaecilia
Taylor 1968, most occurring in the Guianan region (Maciel
and Hoogmoed 2011a). Microcaecilia taylori Nussbaum
and Hoogmoed, 1979 was described from three specimens
collected in two localities in Sipaliwini, Suriname. Recently
new records of M. taylori were provided by Maciel and
Hoogmoed (2011b), who presented for that species a
distribution range from south Suriname to south of the
Amazon river, in the state of Para, Brazil; all Brazilian
records were from west of the Tocantins River.

Here we report an additional record of M. taylori
from the municipality of Rondon do Para (04°19'28" S,
48°06'32” W), state of Para, Brazil, and provide an updated
map of its distribution (Figure 1). On 12 March 2011 a
female specimen of M. taylori (MPEG 32560) was collected

60°W 50°W

ABSTRACT: Microcaecilia taylori is known to occur from the Guianan region to south of the Amazon in the state of Para,
Brazil. Here we provide a new locality record for the species, east of the Tocantins River, 190 km from the nearest record.
The specimen was active under the leaf litter in daylight and is the largest specimen of M. taylori recorded to date.

by (CRMJ) in daylight, around 07:00 h, after a rainy night,
during the opening of a sampling transect in an area of
Amazon Rainforest. The specimen was at the soil surface,
active under the leaf litter. The absence of ova or oocytes
may be because of a recent oviposition, since the oviducts
were enlarged. Our report is the first from east of the
Tocantins River, and extends the distribution of the species
190 km east of the nearest record, in the municipality of
Tucurui in the state of Para.

The specimen, 238 mm in length, is the largest
collected to date, slightly greater than the previous
reported maximum size of 225 mm for M. taylori (Maciel
and Hoogmoed 2011b).
