Type species: Ceropsylla sideroxyli Rileyı by monotypy.

Diagnosis

Adult. Head with genal processes strongly deflexed from plane of vertexı shorter than vertex along midline. Metatibia with 1 + 2 apical sclerotised spurs. Forewing with very long vein R + M+ Cuı which bifurcates into veins R + M and Cu; vein Rs shortı concavely curved towards fore marginı bifurcation of vein M distal to line connecting apices of vein Rs and Cu1a; vein Cu1b very longı distinctly longer that vein Cuı rendering cell cu1 very large. – Last instar immatures. Body almost completely flat dorsally. Antenna shortı conicalı slightly curvedı indistinctly 9-segmented. Humeral lobes developedı ending distal to eye which is enclosed between head sclerite and humeral lobe. Body margined by a singleı dense row of setae; dorsal surface covered by small setae. Inducing pit galls on Sapotaceae .

Redescription

Adult. Medium-sized triozidsı body length 3.4 – 4.4 mm (Figure 2 (aıb)). Integument almost glabrous to imperceptibly granular. Headı in dorsal viewı about as wide as or slightly narrower than mesoscutum (Figure 2 (cıd)); weakly to moderately deflexed from longitudinal body axis in an angle of 15 – 45°; vertex subtrapezoidalı coronal suture fully developed; occiputı in dorsal viewı weakly to moderately concaveı developed as broad transverse band caudad of eyes; lateral ocelli on weakly raised tubercles; frontal ocellus exposedı visible in dorsal view; compound eyes largeı hemispherical; genal processes conicalı subacute apicallyı strongly deflexed from plane of vertexı shorter than vertex along midline. Clypeus pear-shaped; labium moderately longı apex of segment 2 and entire segment 3 clearly visible in profile. Antenna 10-segmented with a single rhinarium on each of segments 4ı 6ı 8 and 9 (Figure 2 (e)). Pronotumı in dorsal viewı forming a weakly curved transverse band; propleurites subrectangular with vertical sutureı proepisternum slightly larger than proepimeron. Metacoxae with moderately longı straightı apically blunt meracanthus; metatibia with a group of small or large genual spines (Figure 2 (g)); with 1 + 2 apical sclerotised spurs. Forewing oblong ovalı with very long vein R + M+ Cuı which is bifurcating into veins R + M and Cu; vein Rs shortı concavely curved towards fore marginı bifurcation of vein M distal to line connecting apices of vein Rs and Cu1a; vein Cu1b very longı distinctly longer that vein Cuı rendering cell cu1 very large (Figure 2 (f)); surface spinules absent apart from base of wing; radular spinules present in the middle of cells m1ı m2 and cu1 along wing margin. Hindwing about two-thirds forewing length; costal setae grouped; vein R + M+ Cu branching into short R + M vein and Cu. Male subgenital plate subglobular (Figure 3 (aıb)). Paramere relatively long and slender (Figure 4 (c ‒ e)). Distal segment of aedeagus shortı simpleı sclerotised end tube of ductus ejaculatorius relatively robustı weakly s-shaped (Figure 4 (fıg)). Female terminalia (Figure 3 (cıd)) shortı cuneateı subgenital plate shorter than proctiger; valvula dorsalis cuneate with a bump in the middle dorsally (Figure 3 (gıh)); valvula ventralisı straightı lacking teeth; valvula lateralis membranousı rounded caudally.

Last instar immatures. Body 1.7 – 2.4 mm long; outlineı in dorsal viewı oval (Figures 5 (aı b) and 6(aıb))ı 1.1 – 1.3 times as long as wide; almost completely flat dorsallyı flat to strongly bulbous ventrally. Antenna shortı conicalı slightly curvedı indistinctly 9-segmentedı with a single rhinarium on each of segments 3ı 5ı 7 and 8 (Figures 5 (d) and 6(d)). Humeral lobes developedı ending beyond eye which is enclosed between head sclerite and humeral lobe (Figures 5 (a) and 6(a)). Caudal plate semicircular (Figures 5 (a) and 6 (a)). Outer circumanal ring smallı 0.2 times as wide as caudal plateı transverseı narrowly rounded or slightly angular laterally; consisting of a single row of poresı sometimes with additional pores laterally (Figures 5 (f) and 6(f)). Body surrounded by a singleı dense row of sectasetae or scale-like setae (Figures 5 (c) and 6(c)); dorsal surface covered by small sectasetae or peg setae (Figures 5 (e) and 6(e)). Body covered with marginal and dorsal waxy secretions (Figure 1 (c)).
