from litter and stream-side woody debris in a mixed forest including
Thuja plicata
,
Abies grandis
, and
Tsuga heterophylla
.
Diagnosis
: Like
C. complicata
,
a small species. The gonopods of
C
.
pectenifera
,
n. sp.
are distinctive. The anterior gonopods share the plan of
C. complicata
,
with the tips much more expanded and hooked, while the anterior branch is considerably stouter and a strong median lobe is present. The posterior gonopod coxites are reduced, especially the main branch, and there are numerous pseudoflagella. The mesobasal knob on the posterior gonopod prefemur is not present in other
Complicatella
species.
Etymology
: The species epithet means “comb-bearer” and refers to the comb-like appearance of the 6–8 pseudoflagellae of the posterior gonopod coxites.
Description
:
Male
holotype
:
Length, 8.0 mm. Ocelli
13–15 in
quadrilateral patch. Metazonites with poorly developed shoulders, segmental setae acute. Color pale tan to off-white, irregularly marked darker. Legpairs one and two reduced, three to six somewhat enlarged, podomeres not conspicuously swollen, femora four to six with knobs. Anterior gonopods (
Figs. 194
,
198
) projecting posteriorly, with large median coxal knob, truncate anterior branch; terminus greatly expanded into two hooked lobes. Conspicuous deep pit laterally (
Fig. 194
). Posterior gonopod coxites (
Figs. 195
,
199–201
) reduced, main branch as short lamella mostly concealed in posterior view by group of 5–8 pseudoflagella. Femur with mesobasal setose knob. Coxae 10 not enlarged, with glands; prefemora 11 with usual processes.

Distribution

type
locality, see Notes.
Notes
:
There is some ambiguity about the
type
locality. In addition to the locality cited above, specimens were also labeled as follows:
WASHINGTON
:
King Co.
,
Snoqualmie National Forest
,
Pratt
Lake
Trailhead
, 1700’ asl,
47°23.821’N
, -

This location and the
Idaho
spot are separated by
260 mi
(
490 km
), which raises doubts about which of the two should be the
type
locality; the gonopods are identical.
However
, the two collection dates are only 2 days apart, which suggests that the specimens were all taken on the same trip.
Possibly
one of them is mislabeled (or mislabeling could have taken place in WAS’ laboratory during curation).
We
decided to use the
Idaho
locality because those specimens were in two different vials with two distinctly different labels (albeit with the same information), one from
William P. Leonard
and the other from CHR.
Further
, the
Pratt
Lake
Trailhead
locality is a well-known locality for the congener
C
.
complicata
, where it has been collected on three different occasions.
Though
it is possible that this represents another disjunct distribution between interior and coastal rainforests in the
Pacific Northwest
as seen in other terrestrial invertebrate taxa (e.g.,
Richart and Hedin 2013
), it seems more likely that this is the result of mislabeling that involved the
Washington
specimens.
