Diagnosis. Pronotum golden castaneous, mottled brown and yellow, with pair of large, irregular brown bands from basal median carina towards posterior process, anterior band fading before reaching humeral angles, second band enlarged posteriorly, interrupted by large irregular white transversal ring at mid-length; males: lateral plate excavated medially, strongly curved inwards, swollen, bearing small dorsal tubercle, mostly visible in caudal view.
Description. Holotype male. Color: pronotum golden castaneous, mottled brown and yellow, with pair of irregular V-shaped bands extended from basal median carina, curved towards posterior process, anterior band fading slightly past humeral angles, posterior band gradually enlarged along the dorsum, interrupted by large irregular spot at about mid-length; apex of posterior process brown spotted yellow, with pre-apical yellow ring. Vertex yellow, variegated with same colors as pronotum. Forewings hyaline, with transverse brown band at apex of basal cell and adjacent area of discoidal cell; coriaceous areas brown and yellow, veins brown spotted yellow for about basal two-thirds, yellow along apical third. Ventral side of head brown; ventral side of thorax, abdomen and legs yellow, legs spotted with brown.
Head: vertex pentagonal, wider than long; ocelli closer to eyes than to each other; area below ocelli strongly concave, lower margins of supra antennal straight in frontal view, distinctly curved forwards in fronto-lateral view; frontoclypeus exceeding half of its length below lower margins of suprantennal ledges, tapering to acute apex. Pronotum: median carina prominent, not strongly keeled at metopidium; humeral angles triangular, well-marked; dorsum slightly elevated, regularly arched; posterior process laterally compressed past mid-dorsum, tapering apically, apex narrow and acute, reaching apex of fifth apical cell (but not fourth); postocular lobes triangular, scoop-shaped.
Forewings: coriaceous areas occupying approximately one-third of clavus and first basal cell, and one-fourth of R cell.
Abdomen: laterotergites IV–VII distinctly lamellar, directed downwards and sideways; VIII sternite slender, wider than long, upper margin with U-shaped excavation. Subgenital plate strongly emarginate basally, sinuate, constricted at basal third or fourth, where lobes separate; lobes elongate, slender, dorsally folded to accommodate branches of aedeagal apophysis, curved to rounded apex. Lateral plate distinctly swollen, with strong medial excavation, strongly curved inwards, dorsal margin constricted into small lobe (visible only in caudal view). Aedeagus U-shaped, lacking tubercles or spines; apophysis slender and elongate, unarmed, arms of apophysis directed upwards, not bifurcate, apex hairy, deflected sideways. Styles comma-shaped, directed upwards to nearly truncate apex, with small ventral projection curved sideways.
Female unknown.
Distribution. ECUADOR (Napo: Reserva Etica Waorani; Sucumbios: Shushufindi; Orellana: Parque Nacional Yasuni).
Measurements. Holotype male (mm): body length: 6.17; pronotal length: 5.25; maximum height of pronotum: 1.50; length of tegmina: 5.25; pronotal width: 2.42; head width: 2.25; vertex width: 1.42; vertex length: 1.17.
Examined material. Holotype male from ECUADOR: Napo: Reserva Etica Waorani [near Parque Nacional Yasuni], ‘ ECUADOR: Napo: Reserva Étnica Waorani; 00°39'10"S, 076°26'00"W; 03.vii.1994 T. L. Erwin et al. col.’, ‘MEM 190: DNA Voucher \ Allodrilus intermedius \ Evangelista \ Evangelista det.’ ( USNM). Paratypes from: ECUADOR: Sucumbios: Shushufindi, ‘ ÉQUATEUR \ VERSANT AMAZONIEN’, ‘SHUSHUFINDI \ 8.X.1985 \ B PERTHUIS REC’ (one male paratype) ( MNHN); Orellana: Parque Nacional Yasuni, ‘ Ecuador, Orellana, Estacion \ Cientifica Yasuni; to UV & \ merc[ury]. vap[or]. Lights \ 20–21 Oct. 2003 \ D. Robacker, W. Warfield & \ M.H. Evans’ (one male paratype) ( USNM).
Notes on type specimens. Holotype minuten mounted, in excellent state of preservation; DNA has been extracted from the whole type specimen (except the abdomen). Paratypes glued to a pinned paper point, in good state of preservation.
Remarks. A. intermedius sp. nov. differs from other Allodrilus species in features of male genitalia, especially the shape of lateral late, which is strongly excavated and swollen in lateral view, bearing a small dorsal tubercle visible in caudal view.
Etymology. The specific epithet, derived from the Latin ‘ intermedius ’ meaning ‘ intermediate ’, indicates that the species is morphologically similar to A. deitzi sp. nov. and A. granulatus sp. nov., except for being smaller, and having a less elevated and tectiform dorsum.
