East Madagascar , Fmpanambo (Sic!) [Fampanambo] ( holotype ), Mananara ( allotype ) . Material examined. Allotype female, labelled: ‘ COLL . MUS. TERVUREN / Madagascar : Mananara / X. 1963 / J. Vadon [p, white label] // ALLOTYPE [p, red label] // Apatenia / quadristigma / Allotypus sp.n. / det. R . Frieser 19780’. [h, partly printed red label] ( ZSMC ). Specimen mounted on triangular point, right antenna (antennomeres III – XI ) mounted separately. Redescription. Female ( allotype ). Measurements (in mm): Total body length—4.33. Head: total length—0.95; length of rostrum—0.44; maximum width of rostrum—0.82; length of eye—0.51; maximum width across eyes—0.96; minimum distance between eyes—0.22. Antenna: length of segments: II—0.15, III —0.17, IV—0.15, V —0.14, VI —0.12, VII —0.12, VIII —0.11, IX—0.36, X—0.16, XI—0.27. Pronotum: maximum length—1.18; width at carina—1.49; minimum width—0.92. Elytra: maximum length—2.11; maximum width—1.78 . Colouration of cuticle generally black, including venter of body, antennae, and legs. Elytra in proximal half partially dark brown. Vestiture. Head, thorax and abdomen uniformly covered with appressed whitish setae. Vestiture on antennae short, appressed to semierect, blackish. All legs covered with dense black setae (longer on ventral faces), dorsal face of all femora, tibiae, and tarsi with narrow, inconspicuous strip comprised of white setae (narrow strips also occur on meso- and metasternum). Elytra with very short, appressed, scale-like whitish setae, except for four characteristic spots, formed by long, wide, whitish setae ( Fig. 5 ). Structure. Head robust ( Figs. 6–7 ), rostrum short, without longitudinal carina, ratio of rostrum length to its maximum width 0.54. Scrobes not visible dorsally. Eyes large, ocular index 0.59. Ratio of maximum width across eyes to maximum width of rostrum 1.17. Antennae ( Fig. 9 ) much shorter than head and pronotum together. Funicle thin, club robust. Pronotum transverse, ratio of length to width at carina 0.79, gradually narrowed anteriorly, widest at dorsal transverse carina. Dorsal transverse carina convex ( Fig. 12 ), dorso-lateral margins moderately directed anteriorly, forming slightly obtuse angle with its dorsal part. Elytra broad, sub-quadratic, narrowed in distal quarter ( Fig. 5 ). Ratio of maximum length of elytra to maximum width 1.18. Each elytron with two conspicuous tubercles in proximal part, one tubercle in humeral part of elytron, second more medial. Abdomen shorter than broad, length of pygidium sub-equal to its width. Female genitalia not examined. Distribution. East Madagascar ( Fig. 19 ).
