( Fig. 1 ) Type material. HOLOTYPUS , male : Philippines : / Luzon Isl ., / Tapsoy, Nagtipunan , / Quirino , 01.2020./ local collector leg. [handwritten]; // HOLOTYPUS: / Synixais / anichtchenkoi sp. nov. / A. Bar š evskis descr. 2022 [red label, handwritten] ( DUBC ) . General distribution: Philippines : Luzon island. Description. Body length: 7.4 mm , body width: 2.5 mm . Dorsal surface of body with grey pubescence, with coarse and moderately sparse rows of brown dots. Lateral portions of elytra with three oblique, smooth, dark­brown smoth spots and covered with long hairs. Fig. 1. Synixais anichtchenkoi sp. nov. (holotypus) Head quadrangular, transverse, flattened, with fine grey pubescence, wrinkled microsculpture and sparse punctation, except dark, shiny, relatively narrow transverse band without pubescence. Eyes relatively small, not extended, markedly bilobate, dorsal and ventral lobes connected with very thin line, poorly visible from above and therefore each lobe seems like separate eye. Cheeks narrow, not extended, with grey pubescence, with elongated hairs near lateral margins of eyes. Clypeus very narrow, shiny, covered with yellow­grey pubescence frontally. Labrum brown, shiny, with yellow­grey pubescence and long setae. Mandibles brown, wide, shiny, with acute apices.Antennae dark­brown, with inner sides densely covered by numerous long setae; basal antennomere elongate, thickened, with fine microsculpture and relatively long hairs; antennomere 2 short, covered with long setae; antennomeres 3–4 with grey pubescence in basal portions, remaining antennomeres unicolor, dark­brown. Pronotum narrower than elytra, with transverse basal impression, covered with grey pubescence and sparse, coarse dark punctures. Basal angles of pronotum rounded, not visible. Legs yellow­brown, covered with grey fine pubescence, with numerous long hairs. Tarsomeres dark, without sparse and grey pubescence on dorsal side. Scutellum widely rounded apically, covered with dense grey pubescence. Pars stridens not visible under basal margin of pronotum. Elytra covered with grey pubescence and darkbrown, sparse and coarse punctures, transversely impressed in mediolateral portions. Lateral sides of each elytron with three oblique, smooth, dark­brown spots. Elytra covered with sparse, coarse, setiferous punctures, with one long dark setain each puncture. Lateral sides of elytra slightly curved. Ventral side of body covered with dense and grey pubescence. Female unknown. Differential diagnosis. Synixais anichtchenkoi sp. nov. differs from other species known from Luzon by the different body shape, coloration and pattern. Pronotum of S. luzonica Bar š evskis, 2019 narrowed in frontal portion (frontal portion of pronotum of a new species is moderately wide).The dorsal surface of body of S . luzonica is covered with bicoloured pubescence, with the domination of yellow­brown tone (the pubescence of a new species is grey). The smooth lateral spots of S . luzonica are differently arranged, the antennae are brown (antennae of a new species are darker). Synixais fantii Barš evskis 2021 can be distinguished from S . anichtchenkoi sp. nov. by the different location of lateral and dorsal spots of elytra, distinctly finer in a new species and located only on lateral portions of elytra.The new species can be distinguished from all species listed above by the distinctly smaller body (the body of both other species> 10 mm ). Etymology. This species is named after my friend and excellent colleague, carabidologist Dr. Alexander Anichtchenko ( Daugavpils University, Latvia ) in appreciation of friendship, excellent cooperation, and in gratitude for his contribution to the studies of Carabidae in the Philippines .
