Pycnostigmus rostratus

: 20
–21.
Type
species by monotypy.
Redescription.
Holotype
FEMALE.
Head
. Shagreened and substantially setose (frons, occiput, cheeks) (
Figs 1
E & 2E). Antenna entirely dark brown/black, scape 1.75x length of radicle, short appressed setae on all 16 flagellomeres, moniliform.
Mesosoma
. Lateral surface of pronotum densely rugulose and pitted; evenly covered in moderately long setae (
Figs 1
B & 2B). Mesopleuron striate except for small area immediately ventrad of mesopleural triangle, and an additional portion immediately dorsal of mesocoxa; dorsal and ventral margins of mesopleural triangle clearly visible, center of triangle setose (
Figs 1
B & 2B). Mesoscutum weakly pitted with small punctures and sparsely setose; cuticle between punctures shiny; notaulices complete, originating at anterior end of parascutal impression; posterior convergence point of notaulices with a small subquadrate, shiny portion of the mesoscutum indented (
Figs 1
C & 2C). Disk of scutellum strongly rugose and deeply pitted, setose along posterior margin; sides not marked by a distinct carina, curving ventrally (
Figs 1
C & 2C); scutellar ridge that separates scutellar fovea often extending to small spine along posterior margin of scutellum.
Metapleural-propodeal complex
. Entire metapleuron covered in long, thin setae (
Figs 1
B & 2B). Propodeum sparsely covered by long setae; cuticle deeply rugulose across entire propodeum. Nucha extended posteriorly, deeply striate (
Figs 1
A, 2A, 1C & 2C).
Metasoma
. Petiole about as long as deep, deeply striate. Syntergum (T2+T3) shiny and smooth; posterior portion of T-3-4 with a brush of setae (
Figs 1
A & 2A). Entire metasoma, in lateral view, about as long as deep.
Wings
. Pseudostigma weakly pigmented, marginal cell visible (
Figs 1
D & 2D).
Legs.
Femora and tibiae black; long setae present. Tarsomeres brown, covered in short, appressed setae (
Figs 1
A & 2A).
MALE.
As
in female except: 18 antennal flagellomeres present; length of metasoma 1.67x depth.
Diagnosis.
Separated from
P. mastersonae
by the head and mesosoma being non-metallic; from
P
.
fossilensis
by having the disk of the scutellum completely rugose (center smooth in
P
.
fossilensis
); from
P
.
incognito
by having the mesopleuron mostly striate (almost entirely smooth in
P
.
incognito
); from
P. hoerikwaggonensis
by having the lateral aspect of the pronotum areolate (striate in
P. hoerikwaggonensis
).
Distribution.
South Africa
: Western Cape (
Fig. 13
).
