Types. Holotype male, paratype male. MALAYSIA. Johor: Tioman Isl. Jungle track 10–600 masl 15– 29.3.2009 V Hula (Prague). Terengganu: Pasir Raja Selatan Forest Reserve , Compt. 52, 29.vi. 2016, B. Nada, ♂ ( PS 52 [4]) ( FRIM). Nada’s collection in forest reserve has compartment number and transect number following in (). # = killed fixed and preserved in 70% ethanol.

Diagnosis. A small species (4.2–4.3 mm long) with distinctive dorsal colouration of black head, pronotum, dark brown to black MN and MS, and brownish yellow elytra which have diffuse darker brown markings in apical ¾, with paler basal markings restricted to basal area near suture, and an accumulation of whitish fat body along apex of suture and round elytral apex.

Description of Male. 4.2–4.3 mm long. Colour ( Figs 309–313 ): pronotum black with narrow brownish orange band across posterior margin; MN and MS black in type, MS with narrow irregular paler brown lateral margins; MN and MS brownish orange in paratypes; elytra of holotype with basal ¼ and suture and lateral margin narrowly brownish orange; rest of elytron in type is diffuse dark brown with apices dark; elytra of paratype with basal paler colour occupying slightly less than basal ¼ and brownish orange colour of suture and lateral margin expanding around apex; head antennae palpi black, scape and pedicel paler on underside; venter of thorax and all ventrites anterior to the LO very dark brown to black; Legs brownish orange; LO in V6, 7 pale creamy white; T2–5 semitransparent grey, T6, 7 black, T8 semitransparent, pale. Pronotum: slightly narrower than humeral width; sides subparallel (A = B = C); posterolateral corners acute. Elytron: subparallel sided; interstitial lines not well defined. Head: GHW 10 x SIW; ASD <ASW; small eye emargination visible along posterior margin of eye (not visible clearly from above); eyes very close but not contiguous on ventral surface. Antennae: very slightly longer than GHW, segments simple scape longer than remainder, scape and pedicel thicker than remainder; FS 4–8 short subequal in length, FS 9 slightly longer than 8. Abdomen ( Figs 312, 313 ): LO occupying all of V6 and 7 with posterior margin of V7 rounded, MPP not developed. T8 with median posterior margin slightly produced and rounded; anterolateral corners narrowly produced and apically acute, length less than posterior entire portion of T8. Aedeagal sheath and aedeagus ( Fig 314 ): sheath sternite with entire rounded apex; median anterior margin of tergite slightly and evenly produced.

Etymology. The type locality is latinised thus Tioman to tiomana, a noun in apposition.

Remarks. The similarly coloured Luciola notaticollis Pic 1914 from Madura India is 7.0 mm long, with black pronotum, MN, and MS, and the basal area of the elytra (slightly less than half the length) orange, with the apical ½ of the elytron black. The type in MNHN was examined but not dissected as it is glued face down on a card. Ballantyne & Jusoh (2016) suggested a closer examination was necessary to determine if L. notaticollis should be assigned to Curtos .
