Moriphila Burckhardt & Cho  gen. nov.

Type species: Moriphila furva Burckhardt & Cho  , sp. nov.; by present designation and monotypy. Gender feminine.

Description. Adult. Small psyllids ( Figs 1 View Figure , 6), total body length 2.5‒3.2 mm. Head ( Figs 3 View Figure , 14 View Figure ) slightly narrower than mesonotum, inclined at 45° from longitudinal body axis (Fig. 6). Vertex rectangular, about twice as wide as long along midline, weakly indented around foveae; covered in sparse, slightly curved microscopic setae (at 100 times magnification); shiny, microsculpture absent from disc; separated from genae by indistinct transverse suture; median suture complete, reaching hind margin of head; genae produced into short, irregularly conical processes; occiput forming narrow ribbon-like sclerite behind compound eye; preocular sclerite absent; frons forming small rhomboid sclerite, delimited by vertex and genae, almost completely covered by median ocellus; compound eye relatively small, subhemispherical. Clypeus hidden by genae in frontal view, pear-shaped; lacking setae; rostrum short, hardly visible in lateral view. Antenna ( Fig. 3 View Figure ) about as long as head width, 10-segmented, segments tubular to slightly conical, elongate (= clavate-type flagellum), segment 3 longest, with a single subapical rhinarium on each of segments 4, 6, 8, and 9; terminal setae shorter than segment 10. Thorax weakly arched dorsally; covered in short, slightly curved setae. Pronotum ( Fig. 3 View Figure ) transversely ribbon-shaped, slightly wider than head, lying in a plane subparallel to that of vertex. Propleurites (Fig. 12) broader than high, slightly oblique; proepimeron smaller than episternum. Metapostnotum flattened medially, with a pair of small, submedian tubercles ( Fig. 8 View Figure , arrow). Forewing ( Fig. 2 View Figure ) oval, coriaceous, less than twice as long as wide; veins on upper surface lined with sparse microscopic setae; pterostigma elongate, not clearly separated from cell r1 by vein R1 which is ending in pterostigma; costal break present; branches of vein M much shorter than their stem; vein Cu1a strongly curved in the middle; m1 cell value 1.0, cu1 cell value 1.5; anal break close to apex of vein Cu1b. Hindwing slightly shorter than forewing; costal setae evenly spaced; vein R+M+Cu splitting into veins R and M+Cu. Mesofemur and mesotibia of male without modifications. Metacoxa ( Fig. 11 View Figure ) with moderately large, apically blunt meracanthus; metafemur with ventral sense organs in basal position, the most distal one slightly offset from proximal pair ( Fig. 15 View Figure ); metatibia lacking genual spine; bearing an open crown of 12‒15 evenly spaced, small apical spurs. Metabasitarsus with two small spurs apically. Male proctiger ( Figs 16, 17 View Figure ) distinctly bipartite; basal portion with well developed, slender posterior processes which form an inward directed hook, bearing long sparse setae on the outer face and a few thicker setae on inner face dorsally; distal segment of proctiger tubular, covered in long setae. Subgenital plate irregularly hemispherical. Paramere lamellar with sclerotised hook on inner face ( Fig. 18 View Figure ). Aedeagus relatively short, proximal segment narrowly curved in basal third; distal segment ( Figs 19, 20 View Figure ) shorter than paramere, inflated in apical half; sclerotised end tube of ductus ejaculatorius strongly modified: joint lacking, membranous part of ductus ejaculatorius ending in a hole which is in a slightly sclerotised plate supported by a sclerotised ring and ending in two sclerotised horns. Female terminalia ( Fig. 23 View Figure ) relatively small, in profile, cuneate. Circumanal ring ( Fig. 21 View Figure ) oval, consisting of two subequal rows of pores. Ovipositor ( Fig. 22 View Figure ) short, simple.

Fifth instar immature unknown.

Etymology. From Morus  and Greek φιλειν = to love, referring to its presumed host association.

Distribution. East Palaearctic.

Host plant. Adults were collected on Morus australis Poir.  ( Moraceae  ) which is a likely host.

Comments. Moriphila  can be separated from other homotomid genera with the key provided by Hollis & Broomfield (1989: 140, 141) in conjunction with the following addition (see also Discussion and conclusion).
