T y p e m a t e r i a l: Holotype ♂: " Kenya E, 600m E of Mwingi Sosoma, 27.11.2011 Snížek lgt" // " HOLOTYPE Augyles davranogloui Skal. Det. Skalický 2019 " [red label] CSU. Allotype ♀: the same data as holotype only, second determinate label is: " ALLOTYPE Augyles davranogloui Skal. Det. Skalický 2019 " [red label] CSU, Paratype ♀: the same data as holotype only, second determined label is: " PARATYPE Augyles davranogloui Skal. Det. Skalický 2019 " [red label] NHML.
D e s c r i p t i o n: Holotype ♂: Total length 2.90 mm (to apex of labrum); elytra 1.80 mm long, 0.70 mm wide across shoulders. Ground colour light chestnut brown without any distinct pattern, labrum darker, eyes black. Labrum (Fig. 9) short, visible part wider than long (ratio 1.35: 1), lateral margins almost parallel; surface finely granulated, setae irregular semi-erect, yellowish and quite long. Mandibles (Fig. 9) short and robust, dorsal subapical tooth short, rounded, dental lobe with two rouned spines. Prostheca with teeth on dental lobe, without prosthecal notch. Antennae 11-segmented, with a 7- segmented club, pedicel oval, scape and pedicel with sparse long erect setae. Head very finely granulated, setae as in labrum. Clypeus (Fig. 9) without pair of anterior horns, anterior margin deeply emarginate, setae as in head. Pronotum as wide as the base of elytra, oval, pronotal base completely rimmed; surface densely regularly granular, punctures approximately as large as 1.5 times eye facets; setae sparse, short, erect, light brown. Scutellum pointed, triangular, lateral margins straight. Elytra with feebly-marked three longitudinal furrows in each elytron (they are clearly visible in wet specimens), without scutellar depressions, humeral depressions shallow and short. Surface of elytra microgranular, with intermixed coarse punctures approximately 2.5 as large as eye facets. Coarse punctures irregular. Setae on elytra light brown, short, erect without longer setae. Epipleural ridges absent. Metaventrite with post-mesocoxal ridge. Mesoventrite with three small rounded spines placed far apart in front of each mesocoxa. Ventral surface sparsely setose. Protibia with 10 stout spines along its lateral margin and two short spines at its inner apical angle, mesotibia with 8 weak and metatibia with 7 thin spines. Tibiae with dense, long setae. Abdomen with complete post-metacoxal ridge. Stridulatory arch marked, without striae. Spiculum gastrale 0.60 mm long, V-shaped as in Fig. 10, arms narrow, firmly connected apically. Aedeagus 0.50 mm long, wellsclerotized; parameres short and completely fused together, firmly connected with phallobasis, penis without internal sac and processus accessories; shape of aedeagus as in Figs. 11-14.
Allotype ♀: The same diameter as in holotype. Elytra without longitudinal ridges. Externally similar to male.
D i f f e r e n t i a l d i a g n o s i s: The shape of the aedeagus, the presence of a complete post-metacoxal ridge, antenomere number and the absence of clypeal horns in the male of A. davranogloui nov.sp. belongs to the parvus group sensu CHARPENTIER (1965). In the Ethiopian region, only two widely distributed representatives of this group are known: A. parvus (GROUVELLE, 1909) and A. breviusculus (CHARPENTIER, 1962) and the new species is probably related to A. breviusculus. The latter species differs from A. davranogloui by its ground colour and elytral pattern (reddish brown to black, dark specimens with an exceedingly diffuse, pale apical spot) and in the morphology of male genitalia (see Figs. 80 and 125 in CHARPENTIER (1965) and Figs 9-14 in this paper).
E t y m o l o g y: The new species is named in honour of Leonidas-Romanos Davranoglou, an excellent Greek entomologist who specializes in hemipteran morphology and taxonomy.
