species:
Psallofulvius dryander
sp. nov.
by original designation.
Diagnosis
. Head more or less prognathous, as long as high in lateral view (
Figs 2G
,
4I
); macropterous, hemelytron elongate, its lateral margins almost parallel (
Fig. 1A
), claval commissure 1.5–2 times as long as scutellum (
Figs 1A
,
2J
,
4E
); antennal fossa placed near suture (not above) between mandibular and maxillary plates; eye reaching ventral margin of head, adjacent to pronotum and covering its anterolateral margin; buccula reaching eye (
Figs 2G
,
4I
); labium reaching at least middle of abdomen; vertex not carinate (2D, 4B); lateral margin of pronotum not carinate (
Figs 2G
,
4I

4B
); body impunctate, clothed in simple setae only, microsetae are hair-like, not modified; metathoracic scent gland evaporative area triangular, almost reaching base of hind coxa (
Figs 2L
,
4K
); labial segments I, II and IV subdivided (
Figs 2B, E, I, N
,
4C, G, H
); forefemora not modified (

Description.
Coloration
. Body mostly brown with dark brown or whitish brown to pale brown markings (
Fig 1
).
Surface and vestiture
. Body mostly smooth or slightly shiny, without punctures or rugosity. Body clothed mostly with adpressed and suberect pale setae, mostly longer than tibia width; setae on pleura and legs adpressed and shorter than tibia width (
Figs 2D, J, L
,
4B, E, K
).
Structure and measurements
. Body elongate (
Fig. 1A
).
Head.
Horizontal, dorsally as long as wide, vertex not carinate, not covering anteromedial margin of pronotum posteriorly; eye not protruding laterally (
Figs 2D
,
4B
); in anterior view head wider than high, base of clypeus placed above ventral margin of eye and antennal fossa, antennal fossa placed above ventral margin of eye, but below eye’s middle line (
Figs 2A
,
4A
); in lateral view head as long as or slightly longer than high, base of clypeus not delimited with depression, buccula reaching eye, distance between buccula and pronotum as long as or longer than buccula length; eye large, extending to ventral margin of head; eye slightly covering anterolateral margin of pronotum; antennal fossa adjacent to eye and placed close to suture between mandibular and maxillary plates (
Figs 2G
,
4I
); antenna shorter than body, antennal segment I not widened, distinctly shorter than head width; segment II cylindrical, as wide as segment I, longer than head width, segment III slightly thinner than segment II; segment IV as long as segment III (
Figs 2D, H
,
4B, L
); labium reaching abdominal segments VI–IX; labial segment I surpassing base of forecoxa, distinctly subdivided in apical half (
Figs 2I
,
4G
); segment II slightly longer than segment I, distinctly subdivided subapically, its apical part 2–3× as long as wide (
Fig. 2B, E
,
4C
); segment III as long as or slightly shorter than segment II, more than 10× as long as wide; segment IV subequal to 1/2–2/3 of segment III, subdivided (
Figs 2N
,
4H
).
Thorax
. Collar flattened, delimited dorsally by a fine line; calli indistinct; posterior margin of pronotum weakly concave (
Figs 2D
,
4B
), lateral margins not carinate (
Figs 2G
,
4I
), propleural suture T-shaped (
Figs 2G
,
4I
); mesoscutum distinctly exposed, scutellum flat (
Figs 2J
,
4E
); mesepimeral apodeme slit-like; mesepimeral spiracle open, slit-like, with distinct microsculpture along anterior margin dorsally; metathoracic scent gland evaporative area triangular, its dorsal margin concave, peritreme slightly upraised, rounded, metepimeron narrow (
Figs 2L
,
4K
).
Hemelytron
. Claval commissure 1.5–2 times as long as scutellum; corial fracture almost reaching middle of corium or slightly surpassing it; embolium distinctly delimited in basal 2/3; cuneus delimited with distinct fracture, not notched; membrane with two cells, forming right angle, distance between cell and membrane apex longer than cell length (
Figs 2J, K
,
4E, F
).
Legs
. Forecoxa shorter than pronotum length, subequal to middle and hind coxae in length and width; forefemur 4× as long as wide, as wide as and as long as middle femur; hind femur twice as wide as and slightly longer than forefemur (
Figs 2M, O
,
4M
); tarsus three-segmented, segments subequal in length or segment I slightly shorter than segment II (
Figs 2F
,

Female genitalia
. See description of
P. dryander
.
Etymology
. The genus name represents the combination of generic names “
Psallops
” and “
Fulvius
”, referring to how the described taxon bears characters associated with both of these genera.
