Type genus

Neophyllura Loginova, 1973 .

Diagnosis

Adult

Head with subtrapezoidal vertex that is separated from genae by incomplete transverse suture; genae forming transverse ridges; frons oval, almost completely covered by median ocellus; preocular sclerite developed, forming large tubercle. Thorax strongly arched dorsally; propleurites with subequal epimeron and episternum. Parapteron elongate, rectangular, much larger than tegula. Metacoxa with moderately large, blunt meracanthus and inconspicuous membranous tubercle on metatrochanteral cavity; metatibia without genual spine, bearing an open crown of 8–9 irregularly spaced, sclerotised, apical spurs; metabasitarsus with 2 spurs. Forewing membrane coriaceous, more or less rugose; costal break developed, pterostigma absent or indistinct; branches of vein M relatively long; anal break close to apex of vein Cu 1b.

Fifth instar immature

Caudal plate with additional pore fields.

Description

Adult

Head, in profile, strongly inclined at almost 90° from longitudinal body axis ( Fig. 3 A–B). Vertex subtrapezoidal, separated from genae by incomplete transverse suture; genae forming transverse ridges; coronal suture fully developed; frons oval, almost completely covered by median ocellus; preocular sclerite developed, forming large tubercle ( Fig. 3C, E ). Antenna 10-segmented, filiform, about as long as head width. Clypeus pear-shaped, visible in profile ( Fig. 3D ). Rostrum very short, hardly exceeding procoxae. Thorax strongly arched dorsally; pronotum transversely ribbon-shaped ( Fig. 3C, E ); mesopraescutum in longitudinal body axis shorter than mesoscutum which is strongly bulged; propleurites with subequal epimeron and episternum. Parapteron elongate, rectangular, much larger than tegula. Legs relatively short, tibiae slightly longer than femora; basitarsi not much longer than broad; metacoxa with moderately large, blunt meracanthus and inconspicuous membranous tubercle on metatrochanteral cavity; metatibia without genual spine, bearing an open crown of 8–9 irregularly spaced, sclerotised, apical spurs; metabasitarsus with 2 spurs ( Fig. 3F ). Forewing oval or rhomboidal, membrane coriaceous, more or less rugose; costal break developed, pterostigma absent or indistinct; vein R shorter than M+Cu or both veins subequal, branches of vein M relatively long; anal break close to apex of vein Cu 1b. Hindwing almost as long as forewing, membranous; costal setae grouped; vein R+M developed. Male proctiger one-segmented; in profile, tubular. Male subgenital plate subglobular. Paramere lamellar. Female terminalia cuneate. Circumanal ring oval.

Fifth instar immature

Caudal plate bearing additional pore fields. Tarsal arolium short, fan-shaped with unguitractor.

Included genus
