Etymology.
The species epithet is a patronym in honor of Steve Goodman, naturalist, author, collector and mammologist who has made substantial contributions to our knowledge of
Madagascar
biodiversity.
Diagnosis.
Uduba goodmani
belong to Group II, the Epigynum lateral projection group, or
Uduba evanescens
group (Map 16). They are ecribellate. Females can be distinguished from those of other
Uduba
species
by the form of the female genitalia (
Figs. 77 A–C
.
80 E, F
):
epigynal plate a broad oval, width 1.50 times length, lateral lobes with convex edges forming ridges on each side (
Fig. 80 E
); vulva broad, width one and-a-half times length with spermathecal ducts characteristic, forming one and-a-half loose, transverse loops (
Fig. 80 F
), copulatory duct lateral and extending mesally to lead to posterior, widely spaced fertilization ducts. Males are unknown.
Description. Male
: Unknown.
Female
(
Holotype
): Total length 16.43. Markings as in
Fig. 7 D
. Carapace 8.50 long, 5.71 wide, 3.50 high; clypeus 0.43 high. Eye diameters: AME 0.27, ALE and PME 0.36, PLE 0.38. Chelicerae 3.79 long; sternum 3.71 long, 2.79 wide; labium 1.82 long; palpal coxae 2.82 long. With a colulus (

Female genitalia
(
holotype

Fig. 80 E
), arising near epigastric furrow, lateral ears (LL side) width 0.75 times LL side length, (LL side) width 0.16 times width epigynum; median lobe a flat plate, each side with an oblique bulge where copulatory openings are found, ML width 0.64 times epigynum width, 1.36 times ML length, CO origin at 0.485 epigynum length from epigastric furrow, distance between copulatory openings 0.41 times epigynum width. Vulva (
Fig. 77 B
) with copulatory ducts lateral, median to these spermathecal ducts forming a single longitudinal loop (
Fig. 80 F
), vulva length 0.53 times width, fertilization ducts widely separated, vulva width only 3.21 times distance between FD.

occurs in montane rain forest.
Distribution.
Uduba goodmani
are known only from two nearby localities on mountains at Andohahela in far southeastern
Madagascar
(Maps 6, 16
)
