One new leafhopper genus
Wang X-D, Zhang Y-L (2018) One new genus and three new species in the leafhopper tribe Coelidiini from the Neotropical Region (Hemiptera, Cicadellidae, Coelidiinae). ZooKeys 794: 85–94.
The male genitalia of the specimens examined were macerated in 10% NaOH and observed in glycerin jelly using an Olympus SZX10 stereomicroscope. All drawings were made using an Olympus drawing tube. A Canon EOS 5D Mark II camera and lifting table controlled by CAMLIFT V2.7.0 were using to take photographs at different focal planes and then stacked by ZERENE STACKER. Photos were also taken by a ZEISS SteREO Discovery.V20 stereomicroscope equipped with a ZEISS Axiocam ICc 5 camera that also provided measurements.
Terminology follows
The generic name refers to the similarity between the new genus and
General color deep brown. Crown light brown with distal 1/4 orange, pronotum and mesonotum pitchy without spots; eyes piceous; forewing with distinct yellow mark on clavus, veins without spots (Figs
Anterior margin of head obtusely angled. Crown midlength produced distally beyond eyes, approx. 1⁄3 of entire length; area between eyes as wide as eye width, surface rugulose, elevated above eyes; lateral margins slightly carinate, not surpassing anterior margin of eyes, slightly convergent basally. Medial length of pronotum distinctly longer than crown and quite shorter than mesonotum (Figure
Valve triangulate in ventral view. Pygofer narrow in lateral aspect, caudodorsal margin produced and tapered in lateral view, without triangular plates at base (Figure
This new genus is similar to genus
Holotype male, PERU: Pasco, 20 km N Villa Rica, 1600 m,
Pygofer with caudoventral processes short, covered with short spines, adjacent to base of caudodorsal processes; aedeagus somewhat tubular, bent at midlength in lateral aspect, apex asymmetrically bifurcate, gonopore apical on ventral surface between bifurcations, dorsal connective absent; style much longer than aedeagus, tapered to acute apex; subgenital plate with dense setae.
The species epithet is derived from the Latin word
Holotype male, PERU: Ancash Region, 4 km NW Carhuaz, Auquipampa,
Pygofer with caudodorsal margin produced as a curved, tapered process, caudoventral processes subbasally, apex slightly enlarged in lateral aspect, extended beyond caudodorsal processes; aedeagus large and broad, lateral edge rolled ventrally, tapered to compressed apical 1/4 in lateral view, apex curved dorsally, gonopore subapical on lateral surface, dorsal connective bifurcate at base, enclosing aedeagus subbasally; style reaching to apex of aedeagus, needle-like with apical third enlarged, corrugated, a small process at subapex; subgenital plate with dense hair-like setae at apical half.
Anterior margin of head obtusely angular. Crown midlength produced distally approx. 1⁄3 of entire length; area between eyes approx. as wide as eye width, surface without wrinkles, elevated above level of eyes; lateral margins parallel, slightly carinate, surpassing anterior margin of eyes distally. Medial length of pronotum longer than crown but shorter than mesonotum (Figure
The specific epithet is descriptive of the expanded aedeagus in dorsal and lateral views.
The new species keys to
Holotype male, BRAZIL: MG, Santuario do Caraça, Cascatona Trl.
Pygofer with caudodorsal margin moderately produced, apex rounded, with two long and narrow processes subbasally, surpassing caudodorsal processes, apex acute; aedeagus somewhat tubular, shaft with serrated flange from subbase to subapex laterally on right, apex symmetrical, bifurcated, gonopore dorsal at apex between bifurcations; style approx. equal to length of aedeagus, very narrow with apical third enlarged, surface rugulose, apex lanceolate; Subgenital plate with very long hair-like setae densely.
Anterior margin of head angular. Crown in middle produced distally approx. 1⁄3 of entire length; area between eyes apparently narrower than width of eyes, surface without wrinkles, elevated above level of eyes; lateral margin slightly carinate, surpassing anterior margin of eyes distally, slightly convergent basally. Median length of pronotum about equal to length of crown and mesonotum (Figure
The species epithet is named for the aedeagus apex being symmetrically bifurcate.
