Coccopsilis scalpta
sp. nov.
Figs 8–9
Diagnosis.
This is the only species of
Coccopsilis
with toothed tarsal claws and empodia that are not entirely vestigial.As for the genitalia (
Fig. 8
), the tegminal apex is deeply incised (↓
3
) (our material is not sufficient to decide how deep the incision is, i.e. whether the parameres possibly are completely separate); the gonostylus, which is clearly tapered from the midlength towards the apex, bears a pectinate claw which is smaller compared with the claws in most other
Coccopsilis
(↓
4
); and the gonocoxal processes are strong with rounded apices (↓
5
). The Far East Russian
C. formosa
resembles
C. scalpta
in having a rather slender, pointed gonostylus with small apical claw, and strong, apically rounded gonocoxal processes. Distinctions of
C. formosa
include the gonostylus being evenly tapered from the base to the apex, and the tegmen being entire and rounded apically. See below the remarks on the
holotype
of that species. Females and preimaginal stages of
C. scalpta
are unknown.
Other male characters.
Body size
1.3 mm
.
Head.
Eye bridge 0–1 ommatidia long at vertex. Antenna as long as both body and wing. 12 flagellomeres; apical flagellomere long, composed of two bodies; circumfila on all flagellomeres. Neck of fourth flagellomere 1.7–1.8 times as long as node (
Fig. 9
). Palpus shorter than head height, 4 setose, subcylindrical segments, apical segment longest of all.
Thorax.
Pronotum with 0–1 seta; anepisternum with 0–1 seta; anepimeron with 2–4 setae.
Wing.
Length / width ratio 3.0–3.4.
Legs.
Foreleg: femur slightly longer than tibia, tibia 0.8 times as long as T
2
. Claws with 1 large tooth basally. Empodia 1/3 claw length.
Genitalia
(
Fig. 8
). Gonocoxal synsclerite with ventromedial setae (usually in
Coccopsilis
the ventromedial portion of the gonocoxae is non-setose); processes long, protruding beyond the parameral apices; dorsoposterior portions short, broad, angular. Gonostylus 2.5 times as long as broad, broadest at about midlength; medial surface flattened, sparsely setose. Aedeagal apodeme thin, slightly longer than parameres, moderately sclerotized with membranous apex. Tegminal apex conspicuously angular.
Etymology.
The Latin adjective
scalpta
means incised, with reference to the tegminal outline found in this species.

Remarks on
C. formosa
.
The
holotype
, the only specimen known of
C. formosa
, has never been appropriately illustrated in literature; there exist only sketches of the aedeagal apodeme and the tegmen (
Mamaev 2001
: fig. 4), both not particularly helpful for identification. The present senior author examined the
holotype
in
October 2012
, which spawned the information used here to compare
C. formosa
with
C. scalpta
.
