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 .

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 View Figure 3 (aıb)). Paramere relatively long and slender ( Figure 4 View Figure 4 (c ‒ e)). Distal segment of aedeagus shortı simpleı sclerotised end tube of ductus ejaculatorius relatively robustı weakly s-shaped ( Figure 4 View Figure 4 (fıg)).

Last instar immatures. Body 1.7 – 2.4 mm long; outlineı in dorsal viewı oval ( Figures 5 View Figure 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 View Figure 5 (d) and 6(d)). Humeral lobes developedı ending beyond eye which is enclosed between head sclerite and humeral lobe ( Figures 5 View Figure 5 (a) and 6(a)). Caudal plate semicircular ( Figures 5 View Figure 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 View Figure 5 (f) and 6(f)). Body surrounded by a singleı dense row of sectasetae or scale-like setae ( Figures 5 View Figure 5 (c) and 6(c)); dorsal surface covered by small sectasetae or peg setae ( Figures 5 View Figure 5 (e) and 6(e)). Body covered with marginal and dorsal waxy secretions ( Figure 1 View Figure 1 (c)).
