Diagnosis.
Cataphractomimus impervius
is most similar to
C. mirapelta
, based on the larger size of these two species compared to the other species in the genus (
Table 1
;
C. burmeisteri
is also smaller), as well as their proportionately larger scapes (compare
Figs 21–22
with
Fig. 23
). However,
C. impervius
and
C. mirapelta
can be separated by the following characters: Inter-tergal plates absent in male
C. impervius
(
Fig. 1
) but present in male
C. mirapelta
(
Fig. 3
); male tergopleurite XI medianly separate in
C. impervius
(
Fig. 1
) but medianly continuous in
C. mirapelta
(
Fig. 3
); subgenital plate proportionately narrower and with a more slender and gently tapering stylus in
C. impervius
(
Fig. 76
) than in
C. mirapelta
(
Fig. 77
); rugose area of male antennae more extensive in
C. mirapelta
(
Fig. 22
) than in
C. impervius
(
Fig. 21
); ventral sclerite of male mesosome clearly delimited laterally and with roughly triangular shape in
C. impervius
(
Fig. 35
) but diffuse laterally and with more or less flat anterior margin in
C. mirapelta
(
Fig. 38
); parameres longer and more slender in
C. impervius
(
Fig. 34
) than in
C. mirapelta
(
Fig. 37
); antero-lateral extensions of mesosome with smoothly rounded anterior margins in
C. impervius
(
Fig. 35
), but with more angular anterior margin in
C. mirapelta
(
Fig. 38
).
Description.
Both sexes.
Head shape, structure, reticulation, and chaetotaxy as in
Figs 1–2
; dorsal preantennal suture not visible in examined specimens. Marginal carina narrow. Head sensillus
s5
situated about as far from
pns
as from
s3
. Thoracic and abdominal plates, chaetotaxy and approximate reticulation patterns as in
Figs 1–2
. Pronotum with deep anterior incision along midline (
Fig. 1
). Inter-tergal plates and internal anterior bulges absent. Tergopleurite XI medianly separate.
Male.
Antenna as in
Fig. 21
; rugose area limited to flagellomere I. Subgenital plate formed from sternal plate IX+X only, separate from sternal plate VIII (
Fig. 76
); reticulation of subgenital plate incomplete medianly; stylus slender (
Fig. 76
). No lateral sternal plates on abdominal segment XI. Basal apodeme as in
Fig. 33
, widening gradually towards distal end. Ventral sclerite of mesosome roughly triangular, separate from mesosome, with several small pores visible near lateral ends (
Fig. 35
). Rugose area of mesosome extensive. Antero-lateral extensions of mesosome with smooth anterior margins. Parameres elongated, slender (
Fig. 34
). Measurements as in
Table 1
.
Female.
Antennae as in
Fig. 2
. Subgenital plate medianly continuous (
Fig. 69
), but with deep anterior incision along midline. Lateral accessory vulval plates with 1–2 microsetae proximally on each side; vulval margin with 13– 17 marginal and submarginal setae on each side (exact position often hard to establish, and therefore here counted together). Subvulval plates slender, not extending much below vulval margin. Measurements as in
Table 1
.
Etymology.
The specific epithet is from “
impervius
”, Latin for “impassable”, referring to the extensive “armour” of the species.
