Diagnosis. Striking species with clear orange pronotum and black elytra, and basal abdominal ventrites very dark brown; LO subparallel sided in V7 and retracted from all margins; V7 with short apically truncated MPP.
Redescription of male. 9.0 mm long. Colour (Figs 382−386): pronotum. MS and MN orange yellow; elytra very dark brown almost black; head between eyes, antennae and palpi very dark brown; venter of thorax dingy orange; legs orange with dark brown tibiae and tarsi; basal abdominal ventrites very dark brown; V6 and 7 creamy white in area of LO, area outside of LO in V7 pale yellow (Figs 383, 385); basal abdominal tergites mid brown; T7 and 8 yellow (Fig. 386). Pronotum (Fig. 384): anterior margin scarcely produced and rounded; lateral margins approach convex sided (B> A, C); pronotal width slightly less than humeral width. Elytron: subparallel sided; interstitial lines not prominent. Head: GHW 6 x SIW; ASD subequal to ASW.Antennae: incomplete, visible segments are elongate slender. Mouthparts: apical labial palpomere laterally flattened of the form of a wide triangle with inner edge dentate. Abdomen (Figs 385−387): well defined apically rounded MPP present; LO in V7 does not reach lateral margins nor into MPP; dorsal surface of V7 not investigated. T8 (Fig. 387): not subparallel sided, lateral margins widening then converging gently, median posterior margin broadly and shallowly emarginated; anterolateral prolongations longer than posterior entire part of T8 and expanded vertically, without ventrally directed pieces at their bases. Aedeagal sheath (Figs 389, 390): posterior margin of sheath tergite slightly sinuous; anterior 6/7 of sternite very narrow, expanding in apical 1/7 with lateral sclerotized pieces of sternite apically divergent, apical margin slightly sinuous, and terminated by paired apically bulbous hairy lobes; posterior margin of sheath tergite slightly sinuous with acute posterolateral corners. Aedeagus (Figs 391−393): elongate narrow, widest across bases of LL; ML extending only half the length of the aedeagus; LL elongate, extending well beyond ML apex and membranous; darker entire base of LL separated along its mid dorsal line for about 1/3 its length; anterior dorsal margin of LL asymmetrical produced on its left side; dissection of specimen in IRNSB had apically membranous portions of LL folded at about half their length and inclining ventrally.
Remarks. Although Damoiseau (1967) did not record a type of this species at IRNSB the similarity of the label data and the identification by Olivier of the single male in IRNSB suggests it could be considered a syntype. This is a distinctive species with some similarities especially in colour to Abs. cerata which has a full LO in V7 reaching to all margins, and no MPP. Ballantyne (1968) observed curvature in the LL of several species she assigned to Luciola (Pygoluciola) and it is probably a post-mortem effect.
