description: Allodrilus colombiensis Flórez-V sp. nov.
Figures 13–14, 28, 39, 50, 87–94.
Diagnosis. Vertex yellow, except for frontoclypeus, entirely dark brown, apex acute; pronotum low, pale yellow, with dark brown band from base of median carina to middle, V-shaped in frontal view; forewings with veins dark brown on basal two-thirds. Males with VIII esternite rectangular; subgenital plate pear-shaped, strongly swollen basally; lateral plate ovoid, bearing small tooth ventrally; branches of aedeagus apophysis not bifurcate preapically.
Description. Holotype male. Color: vertex mostly yellow, dark brown around ocelli, slightly ferruginous along lower margins of supra antennal ledges; frontoclypeus dark brown; ventral side of head yellow. Pronotum yellow, metopidium with longitudinal dark brown band from basal median carina towards posterior process, diagonally enlarged in frontal view, V-shaped, descending towards the lateral margins in lateral view, interrupted by large transluscent white ring; apex of posterior process dark brown. Forewings hyaline, coriaceous areas ferruginous at base, dark macula at apex of first basal cell, first apical cell, and discoidal cell; veins dark brown on basal twothirds, and dull ferruginous on apical third. Ventral side of thorax, legs, and abdomen yellow.
Head: vertex pentagonal, longer than wide; ocelli equidistant to each other and to eyes; area bellow ocelli strongly depressed and concave, lower margins of suprantennal ledges and frontoclypeus straight in frontal view, distinctly curved forwards in fronto-lateral view; frontoclypeus exceeding more than half its length below lower margins of suprantennal ledges, tapering to distinctly acute apex.
Pronotum: median carina prominent, slightly elevated, not keeled anteriorly at metopidium in frontal view; metopidium low, curvilinear above humeral angles; humeral angles triangular, slender; in lateral view, dorsum nearly straight, feebly descending towards apex; posterior process laterally compressed past mid-dorsum, gradually tapering to triangular apex, narrow and acute, reaching apex of fifth apical cell (but not the fourth); post ocular lobes small and flat, apex truncate.
Wings: forewings with coriaceous areas occupying approximately one fourth of clavus, one fifth of R and first basal cell; discoidal cell pentagonal.
Male genitalia: laterotergites IV–VII lamellar, directed downwards, not as laterally projected as in other Allodrilus species; VIII sternite elongated, rectangular. Subgenital plate pear-shaped: truncate basally, not strongly constricted in the middle, strongly swollen in basal third, before lobes separate; lobes moderately elongate, narrowed towards rounded apex. Lateral plate ovoid, not medially excavated in lateral view, with small tooth-like projection ventrally, more visible in caudal view. Aedeagus U-shaped, aedeagal apophysis with one pair of long dorsal spines anteriorly, near aedeagus; arms of apophysis curved upwards, not bifid apically, apex showing toothlike spines. Styles robust, comma-shaped, curved into small hook.
Distribution. COLOMBIA (Amazonas: Leticia).
Measurements. Holotype male/ paratype female (mm): body length: 4.51/00; pronotal length: 3.98/00; maximum height of pronotum: 0.89/00; length of tegmina: 3.6/00; pronotal width: 1.70/00; head width: 1.78/00; vertex width: 0.96/00; vertex length: 1.12/00.
Examined material. Holotype male from COLOMBIA: Amazonas: Leticia, ‘ COLOMBIA, Amazonas / Leticia, Monifue Amena / 4.141667S 69.923256W, 70m / Marzo 2004, G.Fagua leg. / bosque de tierra firme’, ‘ MPUJ _ ENT 0010235’ (MPUJ). One paratype female from COLOMBIA: Amazonas: Leticia, ‘Columbien / Tabatinga / (Amazonas) / 180m / 25.4.1946 ’, ‘leg. L. Richter / Eing. –Nr 18/1958 / 02545’ (ZMUH).
Notes on type specimens. Holotype male (MPUJ) pinned through right side of pronotum between thorax and abdomen, in good state of preservation; abdomen dissected and pinned with specimen. Paratype female (ZMUH) minuten mounted (on a pinned card), also well preserved.
Remarks. A. colombiensis sp. nov. can be readily recognized by conspicous external features, which include the overall coloration, the shape of the head, and the outline of dorsum. Although these features are useful to distinguish this species from the morphologically similar A. alboferrugineus sp. nov., their male genitalia also differ in several respects. In the male of A. colombiensis sp. nov., the lateral plate is ovoid, and bears a small ventral tooth visible in caudal view; the aedeagus shows a single pair of elongate spines at the base of the apophysis, the arms of which are not bifurcate distally; and the subgenital plate is strongly swollen basally before the lobes separate, being much shorter than arms of aedeagal apophysis.
