Notolinopsis janaki nov.sp. ( Figs 4-6 )

E x a m i n e d m a t e r i a l Holotype 3: RCA: W Cape, Table Mts, Echo Valley, 34.7S, 18.27E, Janak 10.X.2013 (cJ); paratypes: same data, 333, 7 ♀♀ (cJ), 333, 2♀♀ (cB); W Cape, Kogelberg NR, Oudebos, 34.20S, 19.00E, Janak 11.XII.2009, 13 (cJ).

D e s c r i p t i o n: Length of body 8 mm; from anterior margin of head to posterior margin of elytra: 4.8 mm. Body with head, pronotum and abdomen coverd with fine and dense, transverse micro-striation, reddish brown with a little darker head; antennae and legs brown. Head sub-rectangular, with sub-rectilinear and sub-parallel sides and strictly rounded posterior angles. Eyes very small and flat. Surface of head with deep, spaced punctation, apart a wide, median stripe. Pronotum longer than head, visibly dilated forward where it is wider than head, with strictly rounded anterior angles, a little oblique anterior margins and feebly sinuate sides. Surface with a punctation similar to that of the head, apart a median smooth stripe. Elytra a little dilated posteriad, shorter and wider than pronotum, with more or less marked humeral angles. Surface shiny, with numerous series of deep, not particularly dense punctation (the distance between the punctures is about equal to their diameter). Abdomen with very fine punctation on the sides.

Posterior margin of the sixth visible sternite with an evident, median lobule.

Tergite and sternite of the male genital segment as in Figs 4-5 . Aedeagus ( Fig. 6 ) 0.90 mm long, sub-spherical, with robust, asymmetric parameres; median lobule large, folded to the left with the organ in dorsal view; inner sac shaped sausage with narrow apexes, covered with small, more or less ovoidal scales.

E t y m o l o g y: Patronymic. Dedicatec to the friend and colleague Jiri Janak.

D i s t r i b u t i o n: The species seems to live in Western Cape region.

R e m a r k s: This specie differs from all the congeners by the peculiar structure of the aedeagus. The species of this genus are divided ( Bordoni 2016) in two groups, one composed of apterous species with small and flat eyes and paler colouration, living especially in the mountains of Kenia and Congo ( N. crateris group) and one composed of brown or black species with small but evident eyes, living in South Africa ( N. diligens group).

B i o n o m i c s: Stream banks, leaf and log litter in indigenous forests.
