description: Genus Ulaikoilia Bílý & Kubáň, gen. nov.   
(Figs. 103–109, 111–115, 122, 129)  
 Type species. Ulaikoilia jelineki Bílý & Kubáň, sp. nov. (present designation).   
 Diagnosis. Body medium-sized (9.8 mm), short, convex, metallic coloured, dorsal surface completely asetose (Fig. 103); ventral surface with microscopic, nearly indistinct pubescence; antennae and legs very short, anal ventrite of male strongly bispinose (Figs. 108, 112), elytra somewhat caudiform; hind wings with anal veins AA 4 +AA 3b +AP 1+2 and AP 3a joined distally (Fig. 122); visible abdominal tergites strongly transverse, terminal tergite (T7) wider than long (Fig. 129); tarsomeres with well-developed adhesive pads, body shape resembling that of Lamprodila, subgenus Ovalisia.   
 Description. Head relatively large, as wide as anterior pronotal margin, frontoclypeus deeply emarginate; frons flat with well-developed, sharp supraantennal carinae (Figs. 106, 109), vertex much wider than width of eye; sculpture of head consisting of sparse, large, simple punctures; eyes large, projecting beyond outline of head; antennae very short (Figs. 105, 114) barely reaching midlength of lateral pronotal margins when reclined, antennomeres 6–11 (in male) twice as wide as long.   
Pronotum strongly convex, without lateroposterior depressions, bell-shaped, posterior margin with wide prescutellar lobe bearing small pit; pronotal sculpture consisting of sparse, simple punctures; lateral pronotal keels barely reaching midlength of pronotum, posterior pronotal angles sharp.  
Scutellum twice as wide as long, obtusely pentagonal.  
Elytra convex, slightly caudiform (Fig. 103), lateral margins sharply serrate in posterior half; apex of each elytron sharply trispinose, each elytron with 10 fine striae, composed of fine, simple, somewhat prolonged punctures, and shortened scutellar stria; humeral swellings small, basal transverse depression wide and deep, not reaching scutellum by far; epipleura missing, elytral margin with large, prominent subhumeral lobe (Figs. 104, 115).  
 Wing as in Fig. 122; anal veins AA 4 +AA 3b +AP 1+2 and AP 3a joined distally.   
Visible abdominal tergites strongly transverse, terminal tergite (T7) wider than long (Fig. 129).  
Ventral surface with simple punctation, punctures finer and denser on ventrites than on remainder of ventral surface; anterior margin of prosternum slightly emarginate medially with deep, wide, transverse groove; prosternal process (Figs. 107, 111) wide and flat, with two deep grooves converging posteriorly; abdominal ventrites (except for anal ventrite) without lateral depressions, anal ventrite of male sharply bispinose (Figs. 108, 112).  
Legs relatively short and stout, male metatibiae not modified; tarsal claws hook-shaped, slightly enlarged at base.  
Aedeagus (Fig. 113) flattened, nearly subparallel, median lobe sharply pointed apically.  
 Etymology. The genus Ulaikoilia gen. nov. (feminine) is named in honour of Mr. Ulai Koil, one of the elder leaders of the Didipa clan from the Baitabag village and an outstanding natural history expert, whose leadership was instrumental in protecting rainforests on the lands of his Didipa clan as the Kau Wildlife area. His enthusiasm and expertise also guided the next generation of the Didipa clan in conservation and study of their rainforests.   
 Differential diagnosis. The genus Ulaikoilia gen. nov. belongs to the subtribe Nesotrinchina subtrib. nov. of the tribe Poecilonotini. Although Ulaikoilia gen. nov. resembles species of the subgenus Ovalisia of the genus Lamprodila by its body shape, the diagnostic characters (presence of well-developed supraantennal carinae, shape of pronotum, elytral apex and prosternal process, microsculpture of dorsal surface and missing elytral epipleura) show that it is related with the genus Nesotrinchus. The characters differentiating Ulaikoilia gen. nov. from related taxa are given in Table 1.
