Limbopsylla Brown & Hodkinson 1988

Limbopsylla p. p. Brown & Hodkinson Diagnosis: Genal processes long and slender. Antennal segment 8 the longest; terminal setae truncate, shorter than segment 10, one setae about half the length of the other. Clypeus pyriform. Forewing obovate, rounded apically; costal break present. Meracanthus prominent; metatibia with genual spine and apical spurs grouped; metabasitarsus with two apical spurs. Biology and damage: The immatures are free-living on the lower leaf surface and secrete conspicuous wax threads (D. Burckhardt, personal observation). Host-plants: Guatteria (Annonaceae) (NHMB data). Distribution: Endemic to the New World (NHMB data). Remarks: Limbopsylla was erected for some unrelated species with unclear relationships (Brown & Hodkinson 1988). Ongoing research (D. Burckhardt, personal observation) suggests that L. nata Brown & Hodkinson is closely related to Platycorypha (Psyllinae). The series from Colombia which we examined (USNM) is an undescribed species close to L. nigrivenis Brown & Hodkinson. The two belong to a group of species developing on Guatteria. Their immatures are clearly of ciriacremine type. Examined material: Limbopsylla sp.: Meta: 4 (male, female), Restrepo, 2-Oct-1965 (J. A. Ramos), USNM.
