Berlandina koponeni Marusik et al., 2014a: 192, figs 30–37 (♂).
Material examined. MONGOLIA: Ömnögovi Aimag: holotype ♂ (ZMMU) unknown locality, sand dune 1.06.1997 (YM); 1♂ (ZMMU) same locality and date (YM); Bayankhongor Aimag: paratypes 9♂ (Nr. 878, NHMB) 8 km OSO von Somon Bajanleg, 1350 m, Sandwüste auf Schotterboden, mit altem Haloxylon - Bestand, hie und da mit grossen Nitraria und Lasiagrostis - Stellen. Geeinzelt vom Boden vom den Pflanzen, unter trockenem Mist und aus dem Sand herausgegraben. 2.VII.1967 (Z. Kaszab); Mongolia, unknown localities, 1 ♀ label "No 190/79" (P. Gajdoš); 1 ♀ label " No 216/79" (P. Gajdoš). CHINA: Inner Mongolia: 4♀ (IZCAS) Hangjing Qi, Erdos, 1290 m, red sand, 5‒7.08.1998 (Xiaodong Yu); 3♀ (IZCAS) Erdos, 1200‒1350 m, 3‒ 10.08.1999 (Hongzhang Zhou, Xiaodong Yu).
Diagnosis. Female of this species is similar to B. hui Song et al., 2004 and B. ovtsharenkoi Marusik et al., 2014. From the former species it differs by the shape of anterior edge of fovea and by broader outgrowths of lateral pockets (Op) (cf. Figs 2, 4 and figs 46‒48 in Marusik et al. 2014a). From B. hui it can be separated by the stronger sclerotized lateral margins of atrium and by the elongate outgrowths of lateral pockets (cf. with figs 17‒18 in Marusik et al. 2014a). The male of B. koponeni differs from those of other species by the long median apophysis and thin and straight embolus. Both sexes of B. koponeni differ from all congeners by the contrasting dorsal pattern of abdomen, consisting of three dark longitudinal stripes connected by chevrons on a light background lacking in other Berlandina species (Fig. 1 and fig 37 in Marusik et al. 2014a).
Description. Female. Total length 10.2. Carapace: 4.4 long, 3.5 wide. Coloration. Carapace yellow with two gray stripes around cephalic area. Chelicerae brown. Sternum, labium and maxillae yellow-brown. Legs yellow. Abdomen beige with gray dorsal pattern: three longitudinal stripes connected by transversal stripes and two white spots in mid part. Spinnerets yellow.

Comments. The species was described on the basis of several males from Southern and South-Western Mongolia. While studying the material collected in the adjacent Inner Mongolia Province of China we found several female specimens belonging to Berlandina with a coloration pattern specific for B. koponeni. Epigynes of these females were very similar to those of B. ovtsharenkoi, sibling with B. koponeni. Correctness of matching of the female and the male is supported by the similarity in the body coloration, comparison with the sibling species and the geographical closeness of findings. Recorded in China for the first time. The new records represent the southernmost locality of the species range.
