Diagnosis. Pronotum golden castaneous, mottled yellow and dark brown; two pairs of londitudinal brown bands (pair at each side of median carina), extended from base of metopidium, V-shaped in frontal view; vertex moderately concave medially; males with lateral plate inflated, excavated dorsally and medially, bearing dorsal finger-like projection, rectangular, truncate at apex; arms of apophysis unarmed, curved upwards and sideways apically.

Description. Holotype male. Color: pronotum golden castaneous, mottled yellow and dark brown; two pairs of V-shaped brown stripes (one pair at each side of median carina) extended from basal median carina towards apex, curved downwards in lateral view, one band reaching lateral margins at mid-dorsum; median carina spotted yellow and dark brown; posterior process with transverse pre-apical yellow ring. Vertex variegated with same colors as pronotum; ventral side of head brown. Forewings hyaline, slightly amber, coriaceous areas brown; veins dark brown spotted yellow along basal two-thirds, yellow on apical third. Ventral side of thorax, legs and abdomen yellow.

Head: vertex pentagonal, slightly wider than long; ocelli closer to eyes than to each other; area below ocelli distinctly concave, lower margins of suprantennal ledges straight in frontal view, strongly curved forwards in fronto-lateral view; frontoclypeus exceeding half of its length below lower margins of supra antennal ledges, tapering to acute apex.

Pronotum: median carina prominent, not strongly keeled anteriorly at metopidium; metopidium low, humeral angles triangular, well marked; in lateral view, dorsum moderately elevated, regularly arched from metopidium to apex of posterior process, highest at middle; posterior process laterally compressed past humeral angles, gradually tapering to triangular apex, narrow and acute, reaching apex of fifth apical cell (but not fourth); postocular lobes scoop-shaped, rounded apically.

Wings: forewings with coriaceous areas occupying approximately one-fourth of clavus, R cell, and first basal cell; discoidal cell pentagonal, almost truncate distally.

Abdomen: laterotergites IV–VII distinctly lamellar, directed downwards and sideways; VIII sternite slightly wider than long, upper margin with V-shaped excavation. Subgenital plate pear-shaped: wider and emarginate basally, sinuate, constricted at basal fourth, where lobes separate; lobes very elongate and slender, gradually tapering to rounded apex. Lateral plate swollen, constricted dorsally and medially into dorsal finger-like projection, distinctly truncate apically, and slightly curved inwards in caudal view. Aedeagal shaft small in comparison to lateral plate and aedeagal apophysis, not showing tubercles or spines; aedeagal apophysis slender and elongate, lacking spines, arms of apophysis curved upwards, not bifurcated apically, apex hairy, slightly deflected sideways. Styles comma-shaped, curved upwards to truncate apex.

Paratype female: larger than male, otherwise identical, except dorsum slightly more elevated and tectiform, broadly arched in lateral view.

Distribution. ECUADOR (Pastaza: Cerros de Abitagua).

Measurements. Holotype male/ paratype female (mm): body length: 7.58/8.17; pronotal length: 6.50/6.42; maximum height of pronotum: 2.0/2.33; length of tegmina: 6.67/7.25; pronotal width: 2.58/2.83; head width: 2.33/ 2.58; vertex width: 1.42/1.58; vertex length: 1.25/1.33.

Examined material. Holotype male from ECUADOR: Pastaza: Cerros de Abitagua [Abitagua Mountain, near Parque Nacional Llanganates], ‘Abitagua, Ecuador \ 1200 Meters \ May.30.1939 \ Wm. Clark—Macintyre’ ( NCSU). One paratype male with same collection data as holotype, plus two labels: ‘Deitz Research \ 72–31a ♂’, ‘ Dysyncritus \ det. L. L. Deitz NCSU 72’ ( DZUP). One paratype female: ‘Abitagua, Ecuador \ 1200 Meters \ May.29.1939 \ Wm. Clark—Macintyre’ ( NCSU).

Notes on type specimens. All specimens glued to a pinned paper point. Holotype lacking left hind leg, abdomen dissected and attached to the same pin, in a good state of conservation. Paratypes also in good condition.

Remarks. A. deitzi sp. nov. generally resembles A. intermedius sp. nov., but is much more robust. The female paratype of A. deitzi —the largest specimen in the genus (~ 8mm)—is identical to the holotype except for a more elevated and tectiform posterior process; its much lighter coloration could be an artifact from collecting or preservation. The species differs from other Allodrilus in a combination of features, including the variegated coloration pattern and the shape of the lateral plate in males, produced into a large finger-like process which is distinctly truncate apically.

Etymology. The male paratype, previously studied by Deitz, was included in his classification of the higher categories of Membracidae ( Deitz, 1975a: 150) . Owing to the relevance of his contributions to treehopper systematics, this newly discovered species is named in his honor.
