Diagnosis
A robust Libellago; as in L. c. dorsonigra ssp. nov., but unlike other Sulawesi Libel -
lago, frons of male black without any pale (blue, orange) markings. Legs dark on innerside
of tibiae, occiput black, lateral lobe of pronotum black without pale
markings, hind lobe of pronotum with extensive transverse marking. Synthorax with
antehumeral stripe wide anteriorly, sharply tapering caudad, in live specimens pale
blue coloured. Differs from L. celebensis dorsonigra by general absence of dark colo
ration on dorsum of abdomen, extremely wide antehumeral marking on mesepisternum
(typically from humeral to mesopleural suture anteriorly), large yellow
markings on ventral side of synthorax and usually a more robust general appearance.
Description of holotype male
Head: Labium with mentum creamish white, base of middle lobe creamish white, remainder
of middle lobe and lateral lobes shining black; labrum black, punctate, semimatt;
mandibles shining black; clypeus with anterior side shining brownish black, in
the corners adjoining labrum with a triangular brown marking, ca half the height of
anterior side of clypeus; genae shining brownish black, remainder of head mattblack,
but with faint indication of paler coloration on frons; large triangular pale blue
postocular spots (Fig. 2b); antennae, including base, black.
Thorax: Pronotum (Figs 3b, 4b) matt-black with bluish yellow markings; anterior
lobe with long transverse stripe, leaving only a narrow black line along anterior margin,
and on ether side a small pale spot on the elevated part of the extreme corners
of the anterior lobe, these spots just connected to or very near the transverse stripe,
and not connected to the paired large triangular markings of median lobe; median
lobe otherwise black; lateral lobe black without pale spots; hind lobe with complete,
rather wide, transverse stripe, somewhat constricted in the middle and retracted from
