Gabrius perodicticus nov.sp. (Figs 10-12)

T y p e m a t e r i a l e x a m i n e d Holotype:, Burundi, NE. Ruvubu-Parc, 25.- 26.iii.1992, Arndt, leg. // Holotypus Gabrius perodicticus nov.sp. Hromádka det., 2013 det., [red oblong label printed] (cHro).

D e s c r i p t i o n: Body length 4.8 mm, length of fore body, (to end of elytra) 2.5 mm. Colouration. Head, pronotum and abdomen brown, posterior margin of all visible tergites narrowly brown-yellow, scutellum and elytra brown-yellow. Maxillary, labial palpi, antennomere 1 and base of antennomere 2 brown-yellow, remaining antennomeres brown, femora and tarsi yellow-brown, tibiae darker.

Head narrow, longer than wide (ratio 17: 15), sides behind eyes nearly straight, posterior angels indistinct. Between eyes four coarse punctures, medial punctures shifted anteriad, distance between medial punctures four times as large as distance between medial and lateral puncture. Eyes flat, twice shorter than temples, posterior angles with one small puncture, temporal area impunctate. Surface with very fine microsculpture consisting of transverse waves.

Antennae long, reaching posterior fifth of pronotum when reclined. Antennomeres 1-3 and 11 distinctly longer than wide, antennomeres 4-7 slightly longer than wide, antennomeres 8-10 as long as wide.

Pronotum longer than wide (ratio 24. 19), anterior angles conspicuously deflexed, vaguely obtusely rounded, posterior angles markedly rounded. Each dorsal row with six approximately equidistant punctures, each sublateral row with two punctuures, puncture two shifted to the lateral margin. Surface with microsculpture similar to that on head.

Scutellum with two coarse setiferous punctures in the middle.

Elytra wider than long (ratio 24: 22), widened posteriad. Punctation coarse and dense, diameter of punctures larger than that on scutellum, separated mostly smaller than one puncture diameter. Surface without microsculpture; setation brown-yellow.

Legs. Metatibia longer than metatarsus (ratio 15. 13), metatarsomere 1 as long as metatarsomere 5, slightly shorter than metatarsomeres 2-3 combined.

Abdomen wide, from visible tergite III narrowed posteriad, first three visible tergites with two basal lines, elevated area between lines impunctate. Punctation at base of all visible tergites finer than that on elytra, becoming sparser towards posterior margin of each tergite. Surface without microsculpture; setation similar to that on elytra.

D i f f e r e n t i a l d i a g n o s i s Gabrius perodicticus nov.sp. may be distinguished from the similar G. thermicola by the antennomere one brown-yellow, paler and wider elytra and by the different shape of the aedeagus.

D i s t r i b u t i o n: Burundi.

E t y m o l o g y: The name of this species, a noun in apposition, is the generic Latin name of the African Slender lori Perodicticus potoo (MÜLLER 1766).
