description: Allodrilus granulatus Evangelista sp. nov.
Figures 17–18, 31, 41, 52, 101 –108.
Diagnosis. Pronotum grayish castaneous, mottled yellow and light brown, with large brown band extended from above humeral angles towards the apex, curved downwards anteriorly in lateral view, interrupted by large, irregular yellow spot near mid-length; dorsal contour line moderately elevated, broadly arched; males: lateral plate deflected inwards, with ventral margin sinuous, constricted into dorsal hook-shaped projection, curved downwards and inwards.
Description. Holotype female. Color: pronotum greyish castaneous, variegated with yellow and brown; in frontal view, three pairs of V-shaped brown bands extended from basal median carina in frontal view, one pair at each side: two bands closer to humeral angles less distinct, curved downwards in lateral view, reaching lateral margins; the third band, much larger and darker, extending over dorsum, widened posteriorly, occupying most of posterior process, interrupted by irregular yellow patch at middle; median carina mottled yellow, with large yellow spot on apical third; apex of posterior process yellow. Vertex with same colors as pronotum, slightly darker at lower margins. Forewings hyaline, with transverse brown macula at R1 and adjacent area of discoidal cell; coriaceous areas brown; veins yellow spotted brown along basal two-thirds. Ventral side of thorax and abdomen dull castaneous, legs yellow spotted brown.
Head: vertex pentagonal, wider than long; ocelli closer to eyes than to each other; area below ocelli moderately concave, lower margins of supra antennal ledges straight in frontal view, distinctly curved forwards in frontolateral view; frontoclypeus exceeding half of its length below lower margins of suprantennal ledges, tapering to acute apex.
Pronotum: median carina prominent, keeled at metopidium in frontal view; humeral angles triangular, slender; 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 triangular, scoop-shaped.
Wings: forewings with coriaceous areas occupying approximately one-third of clavus, R cell, and first basal cell; discoidal cell pentagonal.
Paratype male: smaller than female, otherwise identical. Laterotergites IV–VII distinctly lamellar, directed downwards and sideways; VIII sternite wider than long, heart-shaped (upper margin with U-shaped excavation). Subgenital plate slightly wider and emarginate basally, constricted at basal fourth or fifth, where lobes separate; lobes elongate, slender, dorsally folded to accommodate branches of aedeagal apophysis, narrowed to rounded apex. Lateral plate ovoid, deflected inwards in caudal view, ventral margin sinuous, constricted into dorsal hookshaped projection, directed downwards and inwards, apex rounded. Aedeagus U-shaped, lacking tubercles or spines; aedeagal apophysis slender and elongate, arms of apophysis directed upwards, not bifurcate, slightly enlarged pre-apically, apex acute and hairy, deflected sideways. Styles comma-shaped, with small curved ventral projection.
Distribution. ECUADOR (Napo: Reserva Etica Waorani).
Measurements. Paratype male/ holotype female (mm): body length: 6.58/6.83; pronotal length: 5.92/5.92; maximum height of pronotum: 1.92/2.00; length of tegmina: 5.75/5.83; pronotal width: 2.58/2.83; head width: 2.42/2.58; vertex width: 1.42/1.67; vertex length: 1.17/1.33.
Examined material. Holotype female from ECUADOR: Napo: Reserva Etica Waorani, ‘ ECUADOR: Napo, Tran- \ sect Ent. 1km S Onkonegare \ Camp, Reserva Etnica Waorani \ 00°39’10”S, 076°26’00”W’, ‘ 21-Jun-1994, T. L. Erwin. \ et al., fogging, terre firme \ forest, lot#697’ (USNM). Paratype male: same collection data as holotype, except for lot number in the second label: ‘lot#709’ (USNM).
Notes on type specimens. Holotype and paratype glued to a pinned paper point, in excellent state of preservation. Left forewing of paratype anomalous, with an extra r-m crossvein basad of R1, delimiting a rectangular cell above the regular pentagonal discoidal cell.
Remarks. A. granulatus sp. nov. can be distinguished from other Allodrilus species in having a combination of features that include its general coloration, variegated with brown and yellow, with a large brown patch over the dorsum, and the shape of the lateral plate in the males, strongly curved inwards, hook-shaped in caudal view. In the paratype male, the dorsal contour line is less elevated than in the female.
Etymology. The specific epithet ‘ granulatus ’, derived from the Latin word ‘ granulate ’, refers to the markedly variegate pronotal coloration.
