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
,

).
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.
