Carapoia fowleri Huber, 2000: 243 , figs 18, 962–972 (♂ ♀, Brazil, Guyana?). Huber 2005: 555, figs 87, 88, 97.

Type material. BRAZIL: Amazonas: ♂ holotype, 1♀ paratype, MCZ, Cabo Frio Reserve [~ 2.2°S, 60.0°W], ~ 80 km N Manaus, 1989–1992 (H.G. Fowler).

New records. BRAZIL: Amazonas: 3♂, ZFMK (Ar 19233), Manaus , Reserva Ducke (2.932°S, 59.970°W), 80 m a.s.l., 5–6.xi.2016 (B.A. Huber, L.S. Carvalho) ; 1♂ in pure ethanol, ZFMK (Br 16-333), same data . 3♂ 3♀, ZFMK (Ar 19234), Presidente Figueiredo, forest near Maroaga Cave (2.050°S, 59.972°W), 110–150 m a.s.l., 7.xi.2016 (B.A. Huber, L.S. Carvalho); 2 juvs in pure ethanol, ZFMK (Br 16-341), same data .

Assigned tentatively. BRAZIL: Amapá: 6♂ 3♀, ZFMK (Ar 19235), forest SW Macapá, ‘site 1’ (0.051°S, 51.136°W), 25 m a.s.l., 12.x.2016 (B.A. Huber, L.S. Carvalho) ; 1♂ 2♀ in pure ethanol, ZFMK (Br 16-251), same data . 1♂, ZFMK (Ar 19236), forest SW Macapá, ‘site 2’ (0.051°S, 51.123°W), 20 m a.s.l., 12.x.2016 (B.A. Huber, L.S. Carvalho).

Description (amendments; see Huber 2000). Tibia 1 in 13 newly examined males: 9.9–12.4 (mean 11.1); in six females: 6.4–7.9 (mean 7.3). Diameters femora 1–4 in large male: 0.24, 0.28, 0.29, 0.27. Most males with curved hairs dorsally on tibiae 1 and 4, sometimes also ventrally on tibiae 1, rarely also on femora 1 and 4. Coloration sexually dimorphic: males with orange prosoma, females with pale ochre prosoma with brown marks ( Figs 557, 559 ). Prolateral trichobothrium present on tibia 1. Specimens from Amapá assigned tentatively because pattern of modified hairs on male chelicerae differs slightly (group of ~6 hairs proximally, similar to specimens collected by F.O. Cambridge in Santarém, Breves, and along the “Lower Amazon”; see Huber 2000).

Natural history. The spiders were mostly found in strongly domed, relatively small webs (compared to body size and leg length) among low vegetation close to the ground, exposed rather than hidden in sheltered spaces; juveniles were sometimes found at up to 1 m above ground level. Webs often appeared unusually ‘dirty’, and consistently had a second, flat sheet of silk under the domed main sheet. One female with egg-sac occupied a globular web of only about 6 cm diameter.

Distribution. Widely distributed between Manaus and Belém along the Lower Amazon ( Brazil) ( Fig. 741 ), possibly also in Guyana (see Huber 2000).
