Diagnosis.
Teinomordeus entelosetus
n. sp.
is superficially similar to some
Brueelia
s. str.
, particularly
Br
.
nebulosa
and species from
Turdoides
Cretzschmar, 1826
, which also have abdominal setae in more anterior segments. However,
Te

entelosetus
in the only known species in the
Brueelia
-complex which has
ps
on female abdominal segment II, and females are separated from all
Brueelia
s. str.
on the lack of a cross-piece.
Male
Te
.
entelosetus
are separated from all
Brueelia
s. str.
by the presence of
s3
and the shape of the mesomeral lobes and gonopore (
Fig. 80
).
Description.
Both sexes
. Head shape, structure, and chaetotaxy as in genus description and
Fig. 77
. Preantennal nodi long, slender. Pre-ocular nodi prominent, post-ocular nodi absent. Thoracic and abdominal segments as in genus description and
Figs 75–76
. Sternal plates moderately pigmented, tergopleurites paler.
Male
. Preantennal area short (
Fig. 77
). Scapes approximately twice as long as in female (
Fig. 78
). Pteronotum with 5–6
mms
on each side. Abdominal chaetotaxy as in Table 32 and
Fig. 75
.
Male
genitalia as genus description and
Figs 79–81
. Rugose area of mesosomal lobes restricted to lateral and distal margins. Parameres more or less translucent distally;
pst1
sensillus, submarginal near distal tip;
pst2
seta, lateral near distal tip. Measurements ex
Eurocephalus rueppelli
(n = 11, except TL = 10): TL = 0.99–1.15; HL = 0.28–0.32; HW = 0.27–0.31; PRW = 0.17–0.20; PTW = 0.26–0.32; AW = 0.38–0.43.

Female
. Preantennal area of females (

) longer than that of males. Antennae as in
Fig. 53
. Pteronotum with 5
mms
on each side. Abdominal chaetotaxy as in
Table 2
and
Fig. 76
;
ps
present on segment II. Subgenital plate rounded triangular, reaching vulval margin but not flaring into cross-piece (
Fig. 82
); vague reticulation in at least mid-section. Vulval margin (
Fig. 82
) gently rounded, with 3–5 slender
vms
on each side, 5–6 thorn-like
vss
on each side; 5–6
vos
on each side, the 1–2 distal
vos
median to
vss
. Measurements ex
Eurocephalus rueppelli
(n = 24): TL = 1.20–1.45 (1.35); HL = 0.32–0.35 (0.34); HW = 0.28–0.32 (0.30); PRW = 0.16–0.20 (0.18); PTW = 0.27–0.32 (0.30); AW = 0.39–0.51 (0.44).
Etymology.
The species epithet is formed by Greek “
entēles
” for “complete” and Latin “
seta
” for “bristle”. This refers to the fact that the females have pleural setae on all segments, that is, the “complete set” (
Fig. 76
).
