R e m a r k: The genus Lindenius was revised and keyed by de BEAUMONT (1956) in the western Palaearctic region, and by LECLERQ (1989) in the old world. There is no further processing.

D i a g n o s i s: The male of L. tissintensis keys out with L. effrenus in the key of de BEAUMONT (1956) and LECLERQ (1989). It differs by an all black mesosoma ( fig. 7 View Figs 7-13 , at least pronotum and metanotum yellow in L. effrenus ) and by a straight medial part of ACM ( fig. 9 View Figs 7-13 , more or less waved in L. effrenus ). The special shape of ACM is also a good character to distinguish the new species from the other small species of Lindenius in the species group with antennal segments yellow below and normally rounded in males.

The female keys also out with L. effrenus . It differs by a reduced yellow color pattern: pronotum with two yellow spots, pronotal lobe yellow, scutellum black, femora yellow on extreme apex only ( fig. 10 View Figs 7-13 ), whereas pronotum has a long yellow band, scutellum is all yellow and femora are largely yellow in apical forth in L. effrenus . Also, medial lamalla of ACM is large and straight in L. tissintensis ( fig. 13 View Figs 7-13 ), shorter and rounded in L. effrenus .

D e s c r i p t i o n o f m a l e: 3.5 mm. Color: Black, with the following parts pale yellow. Mandible except red/black apex, AS 1 (scape), remaining antennal segments below, extrem apex of femora, tibiae, tarsi (mid- and hindtibae with black spot below) ( fig. 7 View Figs 7-13 ). Tegula pale transparent, basal sclerite of wing black with yellow margin. Apical margin of tergites reddish pale. S7 reddish, apex transparent. Morphology: Mandible below with lamalla in apical half, shape similar as in L. pygmaeus . ACM: middle section of middle slat is pulled forward in steps, middle section is somewhat wide than the side sections ( fig. 9 View Figs 7-13 ). Flagellomeres rounded. Gena without tooth, hypostomal carina weak. Orbital foveae weakly impressed, for remaining proportions of head see fig. 8 View Figs 7-13 . Medial impression of pronotum as large as midocellus. Mesonotum and scutellum distinctly punctured, punctures approximately. a diameter apart. Upper half of mespleuron shiny and smooth, remaining part with a few minute punctures. Praepectus (sensu LECLERCQ 1989) consists of a row of dense and coarse punctures. Propodeal enclosure basally distinctly longitudinally striate, in apical half smooth with a few indistinct striae ( fig. 11 View Figs 7-13 ). Demarcation to the back wall of the propodeum unclear. T 1-6 with indistinct punctation, T 7 with some larger punctures. Legs without abnormalities, hindbasitarsus narrow.

F e m a l e: 4.1 mm. Agree in general aspects in colour and morphology with the male, except: scape with long brown spot ventrally, Pronotum with two lateral yellow spots, pronotal lobe yellow ( fig. 10 View Figs 7-13 ). Apex of T 2-5 transparent yellowish, pygidial area reddish. ACM: middle section of middle slat is pulled forward in steps, middle section is twice as wide as the side sections ( fig. 13 View Figs 7-13 ). Shape of face see fig. 12. View Figs 7-13

D i s t r i b u t i o n: Southern Morocco, south of Anti Atlas mountains ( fig. 22 View Fig ).

H a b i t a t: All specimens were found in palm gardens, the males by netting in small wheat fields, the female in a yellow pan trap.

E t y m o l o g y Lindenius tissintensis is named after the finding place of the holotype, Tissint, a small village near the Algerian Border in southern Morocco.
