DE1087CC2F44F17BFE31FC68FEBDFCA6.taxon	description	Description. Body (Fig. 1) elongate, strongly constricted between pronotum and elytra, and between elytra and abdomen. Body length less than 2 mm. Head (Figs 2 B – C) rectangular; lacking frontal rostrum, antennal tubercles indistinct; vertexal foveae small and punctiform, lacking sulcus connecting foveae; posterolateral margins of head with row of gold, thick setae; antennae (Fig. 2 A) with 11 antennomeres, clubs formed by apical three antennomeres, antennomeres XI largest, elongate and conical; ocular-mandibular carinae distinct; eyes nearly oval; maxillary palpi with short and triangular palpomeres III, palpomeres IV fusiform, widest at middle; gular region with single fovea just anterior of occipital constriction. Pronotum (Figs 2 B – C) slightly elongate, rounded at lateral margins, constricted and parallel-sided at basal fourth, lacking any foveae or carinae, antebasal spines present, antebasal sulcus distinct at sides, faint in middle; disc slightly convex; lacking paranotal carinae; prosternum with small procoxal foveae. Elytra (Fig. 2 D) constricted at base and at apex; lacking basal foveae, lacking discal striae, with complete sutural striae; lacking marginal striae; weak humeri present. Posterior margin of metaventrite (Fig. 2 E) with small split. Abdomen (Fig. 2 F) constricted at base; tergite V largest, much longer than remaining tergites combined, lacking lateral carinae, with thick, triangular discal carinae; tergites V – VI short, subequal in length, VII as long as V and VI combined. Legs with tarsomeres II slightly longer than tarsomeres III. Males with head, and meso- and metatrochanters modified. Aedeagus (Figs 3 C – E) with parameres fused with median lobe to form elongate ventral lobe. Relationships. The new genus is placed in the group of genera related to Dendrolasiophilus (Fig. 4 A), which also includes the genera Songius (Fig. 4 B) and Tangius (Fig. 4 C). These taxa form a small myrmecophilous lineage within the Asian Batrisitae, sharing a usually glabrous body, presence of a setose tuft at the basolateral margins of the head, and aedeagus with a large basal capsule, and a well-developed dorsal lobe. Lisubatrus can be readily separated from these genera by the elongate antennomeres, a sub-cylindrical pronotum rounded at the lateral margins, elytra strongly constricted apically, and predominantly enlarged abdominal tergite IV. The genera Maajappia Nomura, 2010 (Fig. 4 D) from Japan, and Myrmicophila Yin & Li, 2011 from China may also belong to this group based on the general body form and aedeagal structures, but both these genera lack the cephalic setose tufts (NOMURA 2008, 2010; YIN et al. 2011). Maajappia have a distinct U-shaped sulcus connecting vertexal foveae, and were collected from leaf litter samples, whereas Myrmicophila have modified antennomeres V in the male, and are hosted by Myrmica ants. The key given below serves to a quick separation of Lisubatrus from all these likely allied genera.	en	Yin, Zi-Wei (2017): Lisubatrus dongzhiweii gen. et sp. nov. from the Gaoligong Mountains, China (Coleoptera: Staphylinidae: Pselaphinae).

DE1087CC2F40F178FE73FE4CFB80FB61.taxon	biology_ecology	Biology. The single specimen was collected by a Malaise trap, so the exact habitat of this species is unknown at the moment. However, as inferred from the presence of cephalic setose tufts at the posterolateral margins of the head and glabrous body, which are typical character states shared by a number of allied genera that exclusively include myrmecophilous species, Lisubatrus dongzhiweii is likely an inquiline of ants as well.	en	Yin, Zi-Wei (2017): Lisubatrus dongzhiweii gen. et sp. nov. from the Gaoligong Mountains, China (Coleoptera: Staphylinidae: Pselaphinae).
