propodeal carinae straight and percurrent,
(2) medial propodeal area with one straight
and percurrent longitudinal carina, and
(3) median frontal carina almost invisible.
TYPE MATERIAL: HOLOTYPE: =, Zimbabwe,
Salisbury, 1970-X-23, A. Watsham
coll. (NHM).
DISTRIBUTION: Zimbabwe, Salisbury.
ETYMOLOGY: From Latin, deminuo,
lessen, describing the relatively smaller size
in comparison with othe other species of the
clade.
Paramblynotus angolensis, new species
FEMALE: Length 2.1 mm. Head and
mesosoma black and metasoma and hindlegs
dark bown. Antennae yellow with
distal two segments black. Forewing with
a wide ferruginous band across middle
third and clear both basally and distally.
Hindwing ferruginous aross central half.
Fore- and middle legs brown to yellow
brown.
Antenna 13-segmented; flagellum gradually
expanded apically; median flagellomeres
not constricted. Vertex glabrate with sparse,
fine punctures. Eye prominent, distinctly
extended laterally beyond outer margin of
gena. Distance between posterior ocelli nearly
4.5 times as wide as the distance between
posterior ocellus and eye. Ocellar plate not
raised, defined laterally by a very weak
carina, finely radiating carinae anteriorly
and coriarious posterior to anterior ocellus;
median frontal carina distinct, extended
slightly beyond lower margin of antennal
sockets. Upper face, including antennal
scrobe, coriarious with sparse fine punctures;
antennal scrobe defined by carina laterally.
Lower face coarsely coriarious and superficially
foveate-reticulate. Anterior tentorial
pits conspicuous. Clypeo-pleurostomal sulcus
and epistomal sulcus indistinct. Clypeus
glabrate and punctate. Gena coriarious.
Lateral occipital carina not reaching vertex.
Occiput glabrous.
Anterior flange of pronotum glabrous.
Anterior plate of pronotum glabrous and
finely, sparsely punctate. Pronotum dorsomedially
not distinctly raised; pronotal
crest medially not raised into a process.
Lateral pronotal carina distinct, nearly reaching
pronotal crest dorsomedially. Lateral
surface of pronotum coarsely foveate-reticulate.
Dorsal pronotal area reaching to end of
posterior margin of pronotum and with
closely arranged punctures in a single row.
Mesoscutum distinctly arched dorsally, and
foveate-reticulate with distinct transverse
carinate component. Scutellar sulcus divided
by a single median longitudinal carina;
mesoscutellum foveate-reticulate; posterior
margin narrowly rounded in dorsal view.
Mesopleural triangle ventrally well defined
by smoothly curved carina and with conspicuous
white pubescence. Upper mesopleuron
glabrous except anteriorly with weak, transverse
imbrication; speculum longitudinally
carinate; and median longitudinal impression
percurrent with multiple transverse carinae.
Lower mesopleuron glabrous, pubescent
ventrally. Metepisternum almost entirely depressed
and punctate with long pubescence,
posteromedially with a small area slightly
elevated and glabrate with punctures. Propodeum
mostly areolate-reticulate; lateral
propodeal carina distinct only anteriorly,
and interrupted by a large fovea medially.
Median propodeal area glabrate with a
complete median longitudinal carina crossed
by a transverse carina. Nucha glabrous.
Rs+M of forewing nebulous, arising from
close to posterior end of basal vein. Marginal
cell 2.0 times as long as wide, and almost as
long as submarginal cell. Bulla on Sc+R 1
absent.
Abdominal petiole 0.4 times as long as
wide in lateral view. Relative length of T3–8:
1.8:1.0:2.0:1.3:0.15:0.0; T3–4 glabrous; T5
glabrous anteriorly and finely, sparsely punctate
posteriorly; T6 finely punctate; T8
slightly visible. All legs sparsely punctate
with pubescence except metacoxa dorsally
glabrous and metatibia and metatarsomeres
densely pubescent. Apical teeth of metatibia
long, thin, and pointed apically. 1mt/2–5mt
5 0.63.
MALE: Unknown.
The new species is similar to P. antistatusus,
but it differs from the latter by (1)
forewing ferruginous only medially, and clear
both proximally and distally; and (2) metasomal
T7 of female slightly exposed; exposed
T7 is 1:15 of T6 as measured medially on
lateral side.
