Introduction. The family Lecanodiaspididae includes 12 genera and 85 species. The family is found mainly in Africa, India, Asia and Australia on a range of different plant families. Vea and Grimaldi (2016), in their analysis based on male morphology and molecular analyses, found the Lecanodiaspididae to be sister to the Cerococcidae in a clade with Asterolecaniidae, Kermesidae and Kerriidae. Hodgson & Hardy (2013), in their phylogenetic study based on adult male morphology, found the Lecanodiaspididae sister to the Asterolecaniidae and Cerococcidae. Adult males of the following Lecanodiaspis species have been described: L. acaciae (Maskell), L. africana Newstead (Fig. 76), L. anomala Green and L. brabei Brain (Afifi & Kosztarab 1969); L. baculifera, Leonardi, L. hodgsoni Howell & Kosztarab, L. rufescens Cockerell and L. varioseta Howell & Kosztarab (Amin et al. 1976), and L. elytropappi Munting & Giliomee (Munting & Giliomee 1967) (Fig. 75). The following family diagnosis is based on the above nine descriptions.
Family diagnosis based on adult male morphology (Figs 75, 76). Body: abdomen with very few body setae, all hs; loculate pores absent; simple pores rare. Head: mid-cranial ridge absent dorsally; ocelli absent; with only two pairs of simple eyes; ventral simple eyes placed approximately ventral to dorsal simple eyes; gena without polygonal reticulations; genae with or without a genal tubercle; postocular ridge close to posterior margin of dorsal eyes; interocular ridge absent; ocular sclerite mainly without reticulations; postoccipital ridge well developed; antennae short, about half total body length or rather less; antennae 10 segmented; antennal segment X with 3 capitate setae; both fs and hs present on antennae. Thorax: prosternum with a well-developed transverse ridge but median ridge less well-defined; prothorax without setae; prescutal suture well developed; membranous area of scutum without setae; scutellum with a well-developed, inverted U-shaped, scutellar ridge; postmesospiracular setae absent; basisternum without a median ridge; basisternum without basisternal setae; lateropleurite large, with an extension from marginal ridge; postnotal apophysis well developed; metasternum with very few metasternal setae; metepisternum not sclerotised, and metepimeron sclerotised; alar setae absent; alar lobe present; hamulohalteres usually present; legs quite setose, with fs; trochanter and femur fused, trochanter with sensilla in a line; tibial spurs absent or undifferentiated; tarsi 1 segmented; tarsi with bifurcate setae; tarsal campaniform pores present; tarsal digitules capitate; claw digitules capitate; claws with a small denticle. Abdomen: dorsal abdominal setae few and hs; ventral abdominal setae few and hs; pleural setae few and hs; tergites mainly absent; glandular pouches absent; caudal extensions on segments VII absent; caudal extensions on VIII small and rounded; penial sheath elongate, narrow and parallel sided with a blunt apex; segment IX narrow, only barely differentiated from rest of penial sheath; basal rod quite long; long setae on penial sheath absent, all setae short.
