Type material designated. Holotype ♂ NMP ( Fig. 30 View Figure 30 ): GR ‒ CRETE ANO KERA env. Quercus, Ceratonia beating 35°13'19.4''N 25°27'44.0''E Vétrovec leg. 26.10.2023 [printed]. The two right terminal metatarsomeres are missing. GoogleMaps

Paratypes 8 males (2 BMNH, 1 DTC, 3 JVC, 2 ZKC): same label as holotype .

Etymology. Patronymic. Named for Jaroslav Větrovec (Hradec Králové, Czech Republic) – well-known coleopterist and specialist on Coccinellidae , the collector of the type series.

Description. Holotype male, total body length 2.9 mm. Head 0.6 mm long, across compound eyes 0.6 mm wide, pronotum 0.55 mm long, maximum width 0.5 mm, elytra 1.8 mm long, maximum combined width 1 mm. Selected paratypes 2.8–3.7 mm long. Dorsum and venter brown, base of pronotum, humeral area and irregularly shaped spots in median and

118 apical portion of elytron rufous brown. Mouthparts and antenna rufous brown, terminal antennomere somewhat darkened. Femora brown to rufous brown, tibiae and tarsi yellowish brown. Head about as wide as long, head base and posterior temporal angle rounded. Compound eye moderate, moderately protruding from lateral outline of head, about 1.6‒1.8× as long as converging tempus. Head dorsum slightly glossy, densely and rather large punctate. Intervening spaces smooth, narrower than to (along head midline) twice as wide as punctures. Dorsal cranial setae dirty yellowish, moderately long, rather dense, subdecumbent. Antenna hardly enlarged in apical third. Antennomeres 8‒10 subtrapezoidal, shortened compared to antennomeres 1‒6. Penultimate antennomere distinctly longer than wide. Terminal antennomere elongate, apically rounded, about 1.9× as long as penultimate antennomere. Terminal maxillary palpomere securiform. Pronotum hardly longer than wide, slightly narrower than head across eyes,

Notes on Some Greek Microhoria Chevrolat, 1877 ( Insecta: Coleoptera : Anthicidae ) with New Descriptions and Synonymy subtruncate medially at anterior margin, broadly rounded at anterolateral angles. Pronotal disc slightly glossy, flattened in dorsal aspect. Anterior portion of pronotum much wider than posterior, lateral margins strongly converge in posterior half. Latero-basal pronotal fovea broad and deep. Pronotal punctures larger and coarser than those on head dorsum, dense, variably shaped. Intervening spaces narrower to much narrower than punctures, in part flat in part subsulcate. Dorsal pronotal setation similar to that on head. Scutellar shield small, apically broadly rounded, minutely punctate. Elytra about 1.8× as long as wide, laterally broadly rounded, rounded at apex, dorsally flattened. Humerus distinct, broadly rounded. Apex of elytron modified, apical sutural angle produced into apically rounded denticle-like process and inconspicuously emarginate ahead of it ( Fig. 30C View Figure 30 ). Elytral surface slightly glossy, smaller and sparser punctate than forebody. Intervening spaces variable, generally equally wide as to twice as wide as punctures. Elytral setae pale yellowish, moderately long and dense, not fully appressed, directed posteriorly. Metathoracic wings fully developped (functionnal). Legs without modifications, tibial terminal spurs paired. Basal metatarsomere as long as to slightly longer than combined length of remaining metatarsomeres. Tergite VII subtruncate at posterior margin ( Fig. 31D View Figure 31 ). Morphological sternite VII broad, broadly rounded at posterior margin ( Fig. 31C View Figure 31 ). Tergite VIII narrow, rounded at posterior margin, with a membranous lamina ( Fig. 31E View Figure 31 ). Morphological sternite VIII of two membranous subtriangular sclerites intercomnected by thin membrane ( Fig. 31F View Figure 31 ). Morphological sternite IX Y-shaped, lateral arms short ( Fig. 31G View Figure 31 ). Aedeagus ( Fig. 31A–B View Figure 31 ) broadly cylindrical, apically acutely-pointed; endophallic armature with a pair of long, slightly sinuous, sword-like median spines and paired lateral group of densely arranged, shorter, apically rounded spines which are pointing inwardly except at apex of tegmen, where spines becoming apically acute and are pointing laterally and anterolaterally.

Sexual dimorphism. Female is unknown.

Differential diagnosis. Microhoria vetroveci sp. nov. belongs to the M. longiceps species group as defined by Kejval & Chandler (2020). This species is peculiar among all known congeners in the dorsal body colouration in the combination with the shape of male modified elytral apex and the specific shape of the aedeagus. The dorsal punctures and general appearance similar to that of M. angulapex (C. Koch, 1935) ( Greece ( Dodecanese Islands), W Turkey) but the head base is truncate, the head dorsum is much denser punctured, the elytral humerus obsolete.

Ecology. Specimens were beaten from the foliage of a large Ceratonia sp. ( Fabaceae ) tree at the edge of a Ceratonia grove, under very dry conditions (J. Větrovec pers. comm. 2024).
