Etymology.
The specific name is from Latin
minutus
(small), in reference to the size of the species; adjective.
Diagnosis.
Male can be distinguished from other species as follow: from
I. curva
sp. nov.
by the compound teminal apophysis which is rough distally (
Figs 167
,
173
; bent and S-shaped in
I. curva
sp. nov.
,
Figs 105
,
111
); from
I. hebetata
sp. nov.
,
I. scutata
sp. nov.
and
I. uncinata
sp. nov.
by the relatively short patellar apophysis (
Figs 167
,
173
; 122, 128; 206, 212; 245, 251); from
I. limuensis
sp. nov.
and
I. nigricula
sp. nov.
by the branched and longer patellar apophysis (
Figs 167, 168
,
172, 173
; 135, 136, 140, 141; 180, 181, 185, 186); from
I. ramosa
sp. nov.
by the rough tip of compound teminal apophysis which is bent downward (
Figs 173, 174
; smooth and bent upward in
I. ramosa
sp. nov.
,
Figs 199, 200
); from others by the details of patellar apophysis. Female differs from other species by the shape of epigyne which is approximately darkened on posterior one third portion (
Figs 170
,
175
).
Description. Male

Dorsal prosoma light brown, with dark sides, covered with brown and white setae. Clypeus height 0.05, Clypeus gray brown, covered with light brown setae. Fovea, cervicle and radial grooves unclear. Chelicerae small and yellow, with two promarginal teeth, retromargin with five teeth. Endites, labium and sternum yellow. Leg I with black longitudinal stripes. Metatarsus I with three pairs of ventral spines. Optisthosoma cylindrical, dark brown, with three pairs of yellow spots; anterior margin covered with long brown setae; ventral opisthosoma light yellow. Spinnerets light yellow, anterior spinnerets shorter and stronger than posterior ones. Palp (

,
171–174
): Patellar apophysis wide proximally and pointed distally, with two sharp points. Compound teminal apophysis broad in ventral view, rough and bent distally, with deep groove extending towards the apex. Embolus long and distally curved.
Female
(
Figs 169, 170
,
175, 176, 178, 179
): Total length 2.0, PL 0.9, PW 0.8, OL 1.0, OW 0.8. Eye sizes: AME 0.25, ALE 0.15, PME 0.05, PLE 0.15, AER 0.75, PER 0.7, EFL 0.65. Legs: I 1.6 (0.5, 0.25, 0.35, 0.3, 0.2), II 1.35 (0.4, 0.2, 0.3, 0.25, 0.2), III 1.35 (0.35, 0.25, 0.25, 0.3, 0.2), IV 2.05 (0.6, 0.3, 0.5, 0.4, 0.25); formula: 4132.
Optisthosoma oval, grayish brown, with one pair of pale yellow spots, following two yellow latitudinal stripes. Other characters similar to those of male. Epigyne (

): moderately sclerotized, longitudinal axis darkened, with less sclerotized areas anteriorly. Vulva (
Figs 169
,
176
): Copulatory ducts long and membranaceous, merged at middle of the vulva. Glandular ducts thin and twisted. Spermathecae oval, connect to an irregular sclerite.
