Diagnosis.
Strobila long and usually wide. Scolex large, provided with prominent, protruding, crateriform suckers directed anteriorly. Neck long, narrow relative to scolex width (26–34%). Proglottids craspedote, but velum short or absent. Mature proglottids transversely elongated (length/width ratio 15–36%). Genital pores infrequently (and irregularly) alternating (exceptionally unilateral). Genital ducts pass dorsal to longitudinal osmoregulatory canals. Testes antiporal or antiporal and anterior to ovary, overlapping ventral longitudinal canal antiporally, but not porally. Testes non-overlapping or slightly overlapping with ovary. Cirrus sac short, usually overlapping but not extending beyond ventral longitudinal canal. Vagina shorter than cirrus sac, positioned posterior or postero-ventral to cirrus sac, covered with thick glandular cell layer widening distally, usually not overlapping ventral longitudinal canal. Seminal receptacle elongate, pyriform or ovoid. Early uterus reticulate, anterior, ventral to other organs, with lateral, posteriorly widened, fenestrated “wings”. In cricetid (
Arvicolinae
,
Neotominae
) and geomyid rodents in Eurasia and North
America
.

Remarks
.
Type
specimens of
P. omphalodes
were not designated when the species was characterized, and the cestodes on which the original description (
Hermann 1783
) was based are evidently lost and no longer exist. Tenora & Murai (1980) recognized this problem and proposed designation of a
lectotype
for
P. omphalodes
. The specimen no.
1889 in
the Rudolphi Collection at the Humboldt University (Berlin) was selected on the basis that it represents the oldest known specimen of this species. However, the proposed
lectotype
does not represent any of Hermann’s (1783) original specimens and thus does not have taxonomic standing. The “
lectotype
” of Tenora & Murai (1980) could be redesignated as a
neotype
, but it does not originate from the
type
locality (or local region) for the original series from which
P. omphalodes
was described. We suggest that it is appropriate to find or collect new material in the region of the
type
locality (Alsace in northeastern
France
at the border with
Germany
) for designation of a
neotype
. Further, because DNA sequences have proven to be crucial for systematics of anoplocephalid cestodes, including the genus
Paranoplocephala
(
Haukisalmi
et al.
2004
)
, a specimen with published, or archived, sequence data should have priority when selecting a
neotype
for
P. omphalodes
.
Paranoplocephala
spp. (s. s.) are easily distinguished by their large scolex with prominent crateriform suckers directed anteriorly and narrow neck (relative to the scolex width); in these respects they differ from all other species of
Paranoplocephala
(s. l.). Other characteristic features of
Paranoplocephala
are the short velum, generally wide ventral longitudinal canals and infrequently (and irregularly) alternating genital pores.
The exclusive monophyly of
P. omphalodes
,
P. macrocephala
,
P. batzlii
and
P. jarrelli
, suggested earlier by nuclear (28S rDNA, ITS1) sequences (Wickström
et al.
2005,
Haukisalmi
et al.
2004
), is supported by the present
nad1
data and concatenated
cox1
+
nad1
data. There are no molecular data for
P. microti
,
P. r a us c h i
and
P. maseri
. The sister group of
Paranoplocephala
(s. s.) remains undefined.
