Etymology. Named after the genus Capreolus Gray, 1821 to highlight the resemblance of the antler­like spines of the endophallic armature of the new species to the antlers of male roe deer. Noun in the nominative case, standing in apposition.

Description. Holotype male, total body length 2.3 mm. Head 0.55 mm long, across compound eyes 0.5 mm wide, pronotum 0.5 mm long, maximum width 0.4 mm, elytra 1.4 mm long, maximum combined width 0.85 mm. Selected male paratypes 2.2–2.5 mm, female paratype 2.4 mm long.

Dorsum and venter uniformly black­brown.Antennomeres 1–5 (in part also antennomere six), tibiae and tarsi pale yellowish brown, femora and palps brown. Basal fovea of pronotum with pale brown tinge dorsally and laterally. Head slightly ovoid, about 1.2× as long as wide, tempora moderately constricted towards rounded head base, posterior temporal angles rounded. Compound eye moderate, moderately protruding from lateral outline of head, tempus about as long as to 1.2× as long as eye. Head dorsum moderately glossy, punctures distinct, moderately deep. Intervening spaces generally smooth and glossy, about as wide as punctures. Dorsal cranial setae greyish, moderately long and dense, appressed. Antennae slightly enlarged in apical third. Penultimate antennomere widened distally, slightly longer than wide. Terminal antennomere elongate, acutely pointed, about 2.2× as long as penultimate antennomere, barely longer than combined length of antennomeres 9–10. Pronotum about as long as wide, narrower than head across eyes, subtruncate medially at anterior margin. Pronotal disc moderately glossy, flattened in dorsal aspect. Lateral margins moderately converging in posterior half. Latero­basal pronotal fovea broad, laterally supplemented with moderately long, curved, yellowish setae. Punctures, intervening spaces and dorsal setae similar as those on head. Elytra moderately elongate, about 1.47–1.5× as long as wide, laterally broadly rounded, subtruncate at apex, dorsally flattened. Humerus broadly rounded. Elytron apex modified, with elongate, acutely pointed, narrow denticle at opening of gland channel. Elytral surface glossy and smooth, punctures somewhat larger than those on forebody, shallow. Intervening spaces generally twice as wide as punctures. Elytral setae greyish, rather short, moderately dense, subdecumbent, directed posteriad. Metathoracic wings fully developed. Legs without modifications, tibial terminal spurs paired. Tergite VII subtruncate to truncate at posterior margin. Morphological sternite VII broadly rounded at posterior margin, medially subtruncate. Spiculum gastrale as in Fig. 10J . Aedeagus ( Fig. 10D–I ) elongate. Tegmen apex short, strongly hooked; fused baculi inconspicuous; endophallic armature of two short and strong, slightly curved, basally strongly widened spines, a pair or narrow, pin­like, apical spines and a pair of peculiar, long and strong, bifurcate spines with main branch strongly widened towards apex and truncate apically while secondary (smaller and shorter) branch acutely dentate, rather narrow.

Sexual dimorphism. Female is externally similar to male, elytron apex rounded, without modifications. Female tergite VII broadly rounded at posterior margin.

Interspecific variability. The number of the pale antennomeres and the intensity of pale varies. Differential diagnosis. Microhoria capreolus Telnov & Degiovanni sp. nov. belongs to the M. terminata species group and is externally very similar to a number of uniformly dark coloured congeners but can be differentiated due to the peculiar endophallic armature of the male aedeagus.

Ecology. Collected at elevations 140–1050 m from the ground in river valleys.

Distribution. Southern Turkey (Antalya Province).
