Diagnosis.
Priceiella
(
Thescelovora
)
n. subgen.
is the most aberrant of the four subgenera, from which it is separated by the following characters: dorsal preantennal suture, if present, originates around
dsms
and reaches towards or to
ads
(
Fig. 302
), whereas the suture, if present, in the other three subgenera is restricted to either
ads
(
Fig. 279
) or
dsms
(
Fig. 287
);
aps
absent in male
Pr.
(
Thescelovora
) (
Fig. 300
), and not present on segment IV–V as in the other three subgenera (
Figs 277
,
285
,
307
); mesosome abruptly narrowed anterior to gonopore in
Pr.
(
Thescelovora
) (
Fig. 304
) as in
Pr.
(
Priceiella
) (
Fig. 282
), but unlike
Pr.
(
Camurnirmus
) (
Figs 289
,
297
) and
Pr.
(
Torosinirmus
) (
Fig. 302
), where the mesosome narrows more gradually.
Description.
Both sexes
. As in genus description except: dorsal preantennal suture typically present at
dsms
but extends posteriorly and may reach
ads
(
Fig. 302
); abdominal chaetotaxy as in
Tables 2
and
8
; both sexes without
ps
on segment III; antero-lateral corners of sternal plates not thickened (
Figs 300–301
).
Male
.
aps
absent on male tergopleurites VI–VII, may also be absent on male tergopleurites IV–V (
Fig. 300
). Males without
aps
on tergopleurite III. No accessory sternal plates lateral to male subgenital plate. Proximal mesosome oval to rectangular, markedly narrowed compared to distal mesosome (
Fig. 304
). Gonopore open or closed proximally (
Fig. 304
); if closed often diffuse (not illustrated). Ventral rugose nodi present or absent; if present restricted to lateral margin; 2
ames
microsetae on each side submedianly near gonopore; 2
pmes
sensilla on each side lateral to
ames
. Parameral blades (
Fig. 305
) parallel or slightly divergent distally, typically short.
Etymology.
The name
Thescelovora
is formed by Greek “
theskelos
” for “marvelous” or “wondrous”, and Latin “
vorare
” for “to devour”.
