( Figs 109–110 , 112–114 ).

Indocloeon indonesiae Kluge 2012: 363 (larva, subimago, ♂ and ♀ imagines, egg);

Material examined ( ZIN). Holotype and paratypes: INDONESIA, Lombok Island , Senaru, 19–26.IX.2009, coll. N. Kluge and L. Sheyko: 2 L-S-I ♂, 1 L-S-I ♀, 2 larvae .

Notes appended to original description. The statement that the imaginal antenna has «scapus with dark brown spot near apex, pedicellus with distal half brown» ( Kluge 2012) is not quite correct: actually scapus has two spots, one on the lateral side and another on the median side; the pedicellus does not have the whole distal half brown, but only its median and lateral sides (as in Fig. 92 ) [see Hindocloeon (9)]. Colouration of male and female imagines is as shown in Figs 112–114 . Egg chorion has very fine rugosity ( Fig. 109–110 ).

Distribution: Lesser Sunda Islands: initially described from Lombok ( Kluge 2012), subsequently reported from Sumbawa and Flores ( Kaltenbach & Gattolliat 2017).
