Diagnosis
.
Compared to all the described species of
Microbianor
(see
Logunov 2000
),
M. madagascarensis
sp. n.
differs in having the best-developed and most clearly observable fossae in females (
Fig. 31
; in the rest of
Microbianor
species the fossae are undeveloped or poorly marked). By conformation of their palp, males of
M. madagascarensis
sp. n.
are similar to those of
M. nigritarsis
(cf.
Logunov 2000
: figs 11-12), from which they can be distinguished by yellow tarsi tinged with brown in their basal halves (
Fig. 26
; black in
M. nigritarsis
). Females of both species are quite distinct in the conformation of their epigyne and spermathecae (cf.
Figs 31-32
and figs
18-20 in
Logunov 2000
).
Etymology
.
The new species is named after the area of its occurrence,
Madagascar
.
Distribution
.
NE region of
Madagascar
(Tamatave and Ranomafana).
Description
. Male
(the
holotype
). Measurements. Carapace 1.33 long, 1.15 wide, 0.70 high at PLE. Ocular area 0.98 long, 1.03 wide anteriorly and 1.18 wide posteriorly. Diameter of AME 0.35. Abdomen 1.28 long, 0.95 wide. Cheliceral length 0.45. Clypeal height 0.05. Length of leg segments: leg I- 0.93+0.50+0.65+0.48+0.50; leg II- 0.60+0.36+0.33+0.33+0.26; leg III- 0.68+0.35+0.31+0.38+0.30; leg IV- 0.70+0.35+0.38+0.45+0.33. Leg spination. Leg I: Tb v 1-2-2ap; Mt v 2-2ap. Leg II: Fm d 1ap; Tb pr 0-1, v 1-1; Mt v 2-2ap. Leg III: Fm d 2ap; Tb pr and rt 0-1-0, v 1ap; Mt pr, rt and v 1ap. Leg IV: Fm d 1ap; Tb rt 0-1-0; Mt rt 1ap. Colouration. Carapace russet, shining, with black around eyes; eye field of the same colour as the rest of carapace (
Figs 24-25
). Clypeus russet, with sparse long white hairs forming a triangle and overhanging the chelicerae. Sternum yellowish-brownish. Maxillae, labium and chelicerae russet. Abdomen greyish-yellowish; dorsum, entirely covered with brownish shining scutum and with a pair of transverse white spots (sometimes poorly marked;
Fig. 24
). Book-lung covers and spinnerets yellow, slightly tinged with brown. All legs yellow, with no brown rings, but tibiae I and the basal half of tarsi I brownish (
Fig. 26
). Palps yellow to brownish, but cymbium always yellow; palpal structure as in
Figs 29-30
.
Female
.
(the
paratype
, sample 200.164). Measurements. Carapace 1.38 long, 1.15 wide, 0.65 high at PLE. Ocular area 0.93 long, 1.00 wide anteriorly and 1.16 wide posteriorly. Diameter of AME 0.34. Abdomen 1.55 long, 1.10 wide. Cheliceral length 0.43. Clypeal height 0.05. Length of leg segments: leg I- 0.78+0.40+0.48+0.35+0.30; leg II- 0.58+0.36+0.31+0.33+0.29; leg III- 0.65+0.29+0.33+0.38+0.28; leg IV- 0.75+0.30+0.40+0.48+0.33. Leg spination. Leg I: Tb v 1-2-2; Mt v 2-2ap. Leg II: Tb pr 0-1-0, v 1-1ap; Mt v 2-2ap. Leg III: Tb pr and rt 0-1-0, v 1ap; Mt pr, rt and v 1ap. Leg IV: no spines. Colouration as in the male (
Figs 27-28
), but differs as follows: no scutum on dorsum; book-lung covers and spinnerets yellow; palps yellow; tibiae I brownish. Epigyne and spermathecae as in
Figs 31-32
.
