Type species: Cercoteratura variegata sp. n., here designated.

DIAGNOSIS. Body structure typical of Meconematini : upper rostral tubercle conical, rather short, with slight median groove on dorsum; lower rostral tubercle undeveloped; anterior surface of head almost not oblique; maxillary palpi with apical segment long, thin and almost equal to subapical one in length; pronotum elongated, rather high, with disc slightly convex anteriorly and almost roundly angular posteriorly, with lateral lobe having posterior half more or less gradually narrowing backwards (i.e. practically without humeral notch), and with hind lobe not inflated in both sexes; wings long or insignificantly shortened, with rather narrow tegmina having narrowly rounded apices and (in male) usual stridulatory apparatus;

legs with a pair of oval (opened) tympana, a pair of small and acute apical denticles on hind femur, several moderately long spines and a pair of short apical spurs on ventral keels of fore and middle tibiae, numerous spinules on dorsal keels of hind tibia as well as sparse ones on its ventral keels, and 3 pairs of moderately short spurs on latter tibia. However: last tergite of male with short posteromedian lobe which rather diverse in shape and width ( Figs 72, 73, 82, 83 ); epiproct rather large,

complicated and divided into a pair of lateral lobes by deep posteromedian notch

( Figs 72, 82 ); male cerci strongly curved upwards and situated very close to each other in rest position (middle parts of cerci in this position located between lateral lobes of epiproct; Figs 58, 63, 64 , 73, 82, 83 ); male genital plate normal but narrowed in distal part and with developed styles ( Figs 75, 81 ); male genitalia with large sclerotized or semisclerotized median structure ( Figs 59, 60, 65, 66 ); female abdominal apex unspecialized but with diverse genital plate and with rather long and simple ovipositor ( Figs 61, 67 , 78, 84 ).

67 – C. modesta sp. n.; 68 – Asiophlugis lobata sp. n.; 69 – Xiphidiopsis mada Gor. , stat. n.;

70 – X. ornata sp. n.; 71 – Pseudoteratura sundaica (Kästner) . Male body without posterior part from side/above (57, 62); male abdominal apex with cerci in rest position from side (58,

64) and from behind (63); sclerotized part of male genitalia from above (59, 65) and from side (60, 66); ovipositor with genital plate from side (61, 67–71).

COMPOSITION. Type species; Xiphidiopsis abbreviata Karny, 1924 ; X. spinicauda Sänger et Helfert, 1998 ; C. modesta sp. n.; possibly X. nebulosa Karny, 1924 .

COMPARISON. The new genus differs from all the other genera of Meconematini in the characteristic structure of epiproct and cerci in male (especially in the location of middle cercal parts between the lateral lobes of epiproct in the rest position).

ETYMOLOGY. This new genus is named after the Latinized (from Greek root)

morphological term “cercus” and generic name Teratura .
