Diagnosis
. Recognized by the following set of features: strong brachyptery in both sexes (Figs. 5–8); macropterous forms with hemelytron somewhat narrowed at basal one fourth (Figs. 7–8); endosoma membranous, with large, bifurcated, medial sclerite (
Fig. 31
); left paramere with apical process strongly protruding from paramere body, with distinct tooth situated on medial portion of dorsal surface; sensory lobe somewhat convex, covered with few long, protruding, bristlelike setae (
Figs. 32–33
);
Redescription
.
Brachypterous
male
.
STRUCTURE, TEXTURE, AND VESTITURE
(Figs. 5, 9). Dorsum covered with relatively dense, fine, scalelike, almost reclining setae weakly broadened toward apex.
Head
. Elongated horizontally, conical, weakly rugose (Fig. 5); eye small, reaching gula (Fig. 9); vertex and frons just slightly convex; vertex without occipital carina; antennal segment I cylindrical, mixed with moderately distributed, reclining setae and with few, protruding setae; segment II slightly thickened toward apex, covered with moderately dense, semirecumbent setae; segments III and IV thin, covered with relatively sparse, almost protruding setae; labium thin, with apex somewhat reaching beyond metacoxae; segment I divided medially.
Thorax
.
Pronotum
. Subquadrate, weakly rugose, except for relatively strongly wrinkled posterior portion of pronotal calli, humeral angles and their surrounding area; collar well developed and separated from remainder of pronotum; calli convex, occupying almost entirely surface of pronotum sloping to posterior margin, except humeral angles and small area contiguous with humeral angles (Fig. 5).
Mesoscutum and scutellum
. Scutellum somewhat rugose, mostly flattened with just slightly convex, longitudinal, medial elevation originating from base to apex (Fig. 5).
Thoracic pleura
. Almost without setae; proepisternum and proepimeron shiny; remaining pleura weakly rugose; scent gland efferent system weakly developed, reduced to posterior margin of metepisternum.
Hemelytron
. Rounded laterally; dorsal surface with sculpturation based on very small tubercles forming very small, numerous rounded structures (as on
Fig. 31
); cuneus not separated from remainder of hemelytron by costal fracture; membrane just slightly developed, inner margin weakly overlapping other membrane (Fig. 5).
Legs
. Relatively long; tarsus bisegmented; tarsomere II not subdivided; pretarsal claw toothed subapically.
Macropterous male.
STRUCTURE, TEXTURE, AND VESTITURE
(Figs. 7, 10, 31). Dorsum, thoracic pleura, legs as in
brachypterous
male.
Thorax
.
Pronotum
. Trapezoidal.
Hemelytron
. Lateral margin somewhat constricted at basal one fourth, remainder of lateral margin very weakly rounded; costal fracture present; membrane well developed; major cell relatively small, almost rectangular; minor cell small (Fig. 7).
Male genitalia
.
Aedeagus
(
Fig. 31
). Endosoma membranous with large, bifurcated medial sclerite, which left branch is sharp and long, reaching subapically of endosoma and right branch broadened apically, about two times shorter than left branch; DSS short and indistinct, broadened basally, and nearly cylindrical at apical half.
Left paramere
(
Figs. 32–33
). Apical process strongly protruding from paramere body, with distinct tooth situated on medial portion of dorsal surface; sensory lobe somewhat convex, covered with few long, protruding, bristlelike setae.
Right paramere
(
Fig. 34
). Apical process relatively long, thin perpendicular to paramere body; paramere body ovoid, relatively broad, with bundle of rather short setae dorsally.

Discussion
. The wing polymorphism in the subfamily
Cylapinae
although rare, is present in four out of five currently recognized tribes. Only in the tribe Bothriomirini all known species are macropterous (
Wolski & Gorczyca 2012
). The wing modification present in the genus
Rewafulvius
, with clavus and corium separated and only the inner portion of the membrane overlapping, can be classified as brachyptery
sensu
Schuh & Slater (1995
, according to
Slater 1975
). Within the
Cylapinae
similar modification of the hemelytron can be found in the genera
Fulvius
(
F. s l a t er i
Wheeler) (
Henry et al. 2011
: Fig. 4),
Hemiophthalmocoris
Poppius
(e.g.
H. asthenops
Gorczyca (Gorczyca 2000
:
Fig. 30
A), and in
Rhinocylapoides brachypterus
Wolski & Gorczyca (Wolski & Gorczyca 2011
: Fig. 1). The wing modification most commonly occurring in
Cylapinae
is staphylinoidy. It is found in many species from Australian Region belonging to the genera
Carvalhoma
Slater & Gross (Slater & Gross 1977
: Figs. 6–7),
Fulvioaustrus
Carvalho (Carvalho 1991
:
Fig. 14
),
Austrovannius
Cassis, Schwartz & Moulds
, and
Vanniopsis
Cassis, Schwartz & Moulds (Cassis et al. 2003
: Figs. 3D, 6, 8, 13) and also in Afrotropical
Rhinofulvius albifrons
(Reuter)
(
Gorczyca 2000: 44A
). Coleoptery
sensu
Schuh & Slater (1995)
is present in the genera
Howefulvius
Schmitz & Štys
(Schmitz & Štys 1978: Fig. 1),
Schizopteromiris
Schuh (Schuh 1986
: Fig. 7, 6) (both from the Australian Region),
Brachyfulvius
Carvalho (Carvalho 1955
: Fig. 72) from
Jamaica
,
Corcovadocola
Carvalho (Carvalho 1948
: 2)
from
Brazil
, and
Afrofulvius
Gorczyca (Gorczyca 2000
:
Fig. 20
) from the Afrotropics. Microptery
sensu
Schuh & Slater (1995)
has so far been documented only once, in
Mangalocoris miniatus
Murphy & Polhemus from the Oriental Region (
Murphy & Polhemus 2012: Figs. 1A–D
). The wing modification in
Cylapinae
is found in both sexes (e.g.
Austrovannius
,
Rewafulvius
,
Schizopteromiris
) or occurs only in females (e.g.
Corcovodocola,
Fulvius slateri
).
