Type genus
Amorphicola Heslop-Harrison, 1961.
Diagnosis
Adult
Vertex separated from genae by transverse suture; genae forming conical processes; coronal suture fully developed; frons oval, almost completely covered by median ocellus; anteorbital tubercle and preocular sclerite absent. Antenna with segment 3 longer than segments 7 or 8. Thorax moderately arched dorsally; propleurites with subequal epimeron and episternum. Metatibia without genual spine, bearing 4 irregularly spaced, sclerotised, apical spurs; metabasitarsus with 2 spurs. Forewing rhomboidal, broadly rounded apically; membrane semitransparent; costal break developed, pterostigma large; anal break close to apex of vein Cu 1b. Hindwing with grouped costal setae; vein M+Cu developed. Male proctiger one-segmented; in profile, tubular. Paramere complex, in profile axe or hammer-shaped with several sclerotised peg setae on the inner face.
Fifth instar immature
Body flattened, broadly oval. Antenna 7-segmented, beset with a few short club-shaped setae. Forewing pad lacking humeral lobes, bearing short marginal club-shaped setae. Margin of hindwing pad with club-shaped or capitate setae. Tarsal arolium lacking pedicel. Caudal plate with 4+4 marginal sectasetae and some moderately long club-shaped setae. Anus in ventral position; circumanal ring heart-shaped, consisting of a single row of pores, lacking additional pore fields.
Description
Adult
Head, in profile, weakly to moderately inclined at 30–45° from longitudinal body axis (Fig. 5 A–B). Vertex subtrapezoidal, separated from genae by transverse suture; genae forming conical processes which are separated or contiguous at base; coronal suture fully developed; frons oval, almost completely covered by median ocellus; anteorbital tubercle and preocular sclerite not developed (Fig. 5 C–D). Antenna 10-segmented, filiform, 1.0–1.5 times as long as head width, segment 3 longer than segments 7 or 8. Clypeus pear-shaped, slightly flattened, hardly visible in profile. Rostrum short, distinctly exceeding procoxae. Thorax moderately arched dorsally (Fig. 5 A–B), slightly narrower than head; pronotum ribbon-shaped; mesopraescutum in longitudinal body axis about as long as mesoscutum; propleurites with subequal epimeron and episternum. Legs moderately long, tibiae slightly longer than femora; basitarsi not much longer than broad; metacoxa with moderately large, horn-shaped meracanthus; metatibia without genual spine, bearing 4 irregularly spaced, sclerotised, apical spurs; metabasitarsus with 2 spurs (Fig. 5B). Forewing rhomboidal, broadly rounded apically (Fig. 5A); membrane semitransparent, covered in irregularly spaced surface spinules; costal break developed, pterostigma large; vein R longer than M+Cu; anal break close to apex of vein Cu 1b. Hindwing almost as long as forewing, membranous; costal setae grouped; vein M+Cu developed. Male proctiger onesegmented; in profile, tubular. Male subgenital plate subglobular or elongate. Paramere complex, in profile hammer-shaped (Fig. 5B) with several sclerotised peg setae on the inner face. Female terminalia cuneate. Circumanal ring oval.
Fifth instar immature
Body flattened, broadly oval. Antenna 7-segmented, beset with a few short club-shaped setae; bearing a single subapical rhinarium on each of segments 3 and 5, and 2 rhinaria on segment 7. Forewing pad lacking humeral lobes, bearing short marginal club-shaped setae. Margin of hindwing pad with clubshaped or capitate setae. Legs bearing club-shaped or capitate setae; tarsal arolium longer than claws, fan-shaped with unguitractor but lacking pedicel. Caudal plate developed, semi-circular; margin with 4+4 sectasetae and some moderately long club-shaped setae. Anus in ventral position; circumanal ring heart-shaped, consisting of a single row of pores, without additional pore fields.
