Type material. HOLOTYPE: ♀ “ YEMEN, SOCOTRA Island , Kesa env., 220-300m, N 12°39′37″ E 53°26′42″, 28.- 29.i.2010, L. Purchart leg. // HOLOTYPE / Kesaflata / lubosi sp. nov. / det. A. Stroiński, I. Malenovský / & D. Świerczewski 2016” ( MMBC, dry-mounted, abdomen detached, dissected and stored in a plastic vial with glycerol under the specimen).

Diagnosis. The only species in the genus.

Description. Measurements. Total length 5.65 mm. Vertex: A/B 2.33. Frons: C/ E 0.50; D/ E 0.93. Pronotum: F/B 2.20. Mesonotum: G/F 2.27, G/B+F 1.56, G/H 0.70. Tegmina: I/J 2.25.

Coloration. General coloration light brown with darker patches on the apical top of frons, lateral margins of vertex, pronotum and mesonotum as well as tegmen – alongside sutural angle and MP vein and on claval disc and depression; abdomen brownish ( Figs 53–57 ).

Structure. Head. Median carina of frons sharp, lateral carinae short, sinuate, apically curved to lateral margins ( Figs 56 , 65 ). Clypeus convex ( Fig. 56 ).

Thorax. Posterior margin of pronotum deeply concave. Groove of mesonotum short ( Figs 57 , 61–63 ).

Male unknown.

Female terminalia. Pregenital sternite with anterior margin weakly arcuate and posterior margin convex. Gonoplac posterior margin with row of larger teeth and row of smaller teeth ( Fig. 72 ). Gonapophysis VIII with keels of ventral margin short and parallel; ventral margin ending with blunt teeth ( Fig. 73 ). Spermatheca with ductus receptaculi ribbed, widening apicad; diverticulum ductus smooth, basal part tubular, apical part widened with subapical, shallow incision ( Fig. 74 ).

Etymology. Named after our dear colleague Luboš Purchart (Mendel University, Brno) who collected the holotype.

Habitat and occurrence in Socotra. The only specimen available was collected in a semi- arid shrubland dominated by Jatropha unicostata , Croton socotranus , Euphorbia arbuscula, Adenium obesum , Dendrosicyos socotrana , Sterculia africana , and Cissus subaphylla on lower altitude rocky slopes at foothills of the Maaleh hills at the north-western coast of Socotra ( Figs 78, 79 ).

Distribution. So far only known from the semi-arid zone of north-western Socotra.
