Diagnosis.
Recognized by shiny body and brownish general coloration (
Fig. 10
), spots on the head; endosoma with medial left sclerite elongated and smooth (
Fig. 45
), ventral right sclerite with trichia on surface (
Fig. 53
), and apex of dorsal right sclerite acute (
Fig. 53
).
Redescription. Male:
COLORATION
: Shiny, brownish with black areas. Head: Black, transversal pale spot (V-shaped) posterior to longitudinal sulcus, two triangular spots between eyes, both yellowish; eye brown; mandibular plate, maxillary plate and apex of buccula, black; labium brown with black apex; clypeus black; frons with black adjacent part; antennal segments brown. Thorax: Pronotum: Brown, collar yellow, calli and lateral margins of pronotum, dark brown; inner region of calli, black; two distinct large rounded spots behind calli, black; proepisternum with pale spot in dorsal region, dark brown in median region and yellow in margin; scutellum black with a pale longitudinal spot. Hemelytra brown; clavus and membrane dark brown; embolium, cuneus and median region, brown; ostiolar peritreme pale brown; abdomen black.
VESTITURE AND STRUCTURE
: Head: Slightly broader than long (Table 1), antennal segment I, 0.9 times width of head (Table 1), two times width II; segment II, 3 times longer than segment I (Table 1). Thorax: Pronotum with anterior lobe gradually narrowed and golden long sparse and erect pilosity.
MEASUREMENTS
: See Table 1.
GENITALIA:
Pygophore: triangular(
Fig. 20
), with left lateroposterior projected margin (
Fig. 20
). Parameres: Left paramere sickle-shape dorsal margin of basal sensory lobe almost straight and ventral margin of basal sensory lobe clearly convex; hypophysis with a sharp lateral projection (
Fig. 32
), right paramere as in
Fig. 32
. Endosoma: Medial left sclerite fusiform with wide basal region and smooth (
Fig. 45
); ribbon like sclerite with short lobe or area beneath secondary gonopore covered with microtrichia (
Fig. 45
); ventral right sclerite elongated with trichia on surface, and dorsal right sclerite fusiform with apex acute and smooth (
Fig. 53
).
Female (description):
Similar in structure and coloration to male, but slightly longer (Table 1).
MEASUREMENTS
: Table 1.
GENITALIA:
First gonapophysis: With broad apical grooved region (
Fig. 66
). Second gonapophysis: Apex triangular, with one teeth (
Fig. 9
e). Dorsal labiate plate with small sclerite caudal to sclerotized rings (
Fig. 100
). Posterior wall with rounded interramal lobes, and anterior angle narrow projected to a blunt tip (
Fig. 100
). Dorsal structure small and medial process absent (
Fig.100
).
Geographic distribution.
Known only from Eastern Africa (
Tanzania
) (Schuh
2002–2014
). New records from: Central Africa (
Democratic Republic of the Congo
) (
Fig. 107
).
Plant associations.
Unknown.
Discussion.
Collaria obscuricornis
is easily distinguished from
C.improvisa
by the shiny body, transversal pale spot (V-shaped) posterior to longitudinal sulcus, dark brown spots on hemelytra, medial left sclerite of endosoma in male and by the posterior wall in female. We did not examine the
Holotype
of
C. obscuricornis
, but examined the photographs of a single male which is deposited at Naturhistoriska riksmuseet (Swedish Museum of Natural History) (NHRS), and bears labels with Poppius’s handwriting.
