Description.
Body length
6.1 mm
, length of fore body (to end of elytra)
3.5 mm
.
Colouration. Head black, pronotum, scutellum, elytra and abdomen black-brown, mandibles, maxillary and labial palpi brown, apex of labial and maxillary palpomeres 3 yellowbrown, antennae black, femora and tarsomeres 5 of all tarsi brown-yellow, tibiae and remaining tarsomeres dark brown.
Head transverse, markedly wider than long (ratio 27: 20), parallel-sided. Posterior angles obtusely rounded. Eyes flat, slightly longer than temples (ratio 8: 7). Four coarse punctures present between eyes, distance between medial interocular punctures four times as large as distance between medial and lateral puncture. Medial punctures distinctly shifted anteriad. Middle portion of head with wide impunctate median area, each side and temple area with several variably large punctures. Posterior margin of each eye with two coarse punctures. Surface without microsculpture.
Antennae very long, exceeding posterior margin of pronotum by antennomeres 10 and 11 when reclined. All antennomeres longer than wide. Relative lengths of antennomeres 1–11: 1 = 10 units, 2 and 3 = 7 units, 4 = 6 units, 5 and 6 = 5.5 units, 7–10 = 5 units and 11 = 6 units.
Pronotum highly convex, wider than long (ratio 30: 28), anterior angles conspicuously deflexed, vaguely obtusely rounded, posterior angles markedly rounded. Each dorsal row with 4–5 large punctures, and 9–10 small punctures, middle portion of pronotum with wide impunctate longitudinal band. Each side with many irregularly arranged small punctures and several large punctures between them. Surface without microsculpture.
Scutellum very finely punctate, punctures smaller than eye-facets and separated by two puncture diameters in transverse direction; setation black.
Elytra combined wider than long (ratio 38: 33), hardly widened posteriad. Punctation very fine and sparse, punctures smaller than eye-facets, separated by 2–3 puncture diameters. Surface without microsculpture; setation dark.
Legs. Metatarsus about as long as metatibia. Relative lengths of metatarsomeres 1–5: 1 = 10 units, 2 = 5 units, 3 = 4.5 units, 4 = 4 units and 5 = 7 units.
Abdomen wide, very slightly narrowed towards apex. First three visible tergites with two basal lines, elevated area between lines with scattered punctures. Punctation of visible tergites finer and much sparser than that on elytra, becoming sparser towards posterior margin of each tergite. Surface between punctures without microsculpture. Setation similar to that on elytra.
Male. Protarsomeres 1–4 simple, each with few modified pale setae laterally. Sternite VIII (
Fig. 16
), sternite IX (
Fig. 17
), aedeagus (
Figs. 13–15
).
Female. Unknown.
Differential diagnosis.
Pseudohesperus tauraco
sp. nov.
may be distinguished from
P. tyto
sp. nov.
by a narrower and sparser punctation of the head and a different shape of the aedeagus and from
P. proselytus
by a wider head, shorter antennae and denser punctation of the scutellum.
Etymology.
The name of this species, a noun in apposition, is the Latin generic name of the African red-crested turaco
Tauraco
erythrolophus
(Vieillot, 1819).
Distribution.
Democratic Republic of the Congo
