Description: Habitus and coloring ( Fig. 3 ) similar to Scopaeus javanus ( Figs 1, 2 ) and S. riedeli ( Fig. 4 ), different as follows: Brachypterous form, possibly dominant according to type specimens, with or without palisade fringe at posterior margin of abdominal tergite VII; only one specimen from Lombok macropterous with fully developed metathoracic wings. Unicolorous orange-brown specimens unknown. Total body length 3.0 – 3.3 mm ; forebody length 1.6 – 1.7 mm . Male: Abdominal sternites VII and VIII ( Fig. 120 ) as in S. javanus ( Fig. 119 ) and S. riedeli ( Fig. 121 ). Aedeagus ( Figs 28 , 53 – 55 ) about 0.8 mm long, similar to that of S. javanus ( Figs 27 , 50 – 52 ) and S. riedeli (29, 56 – 58), but different as follows: Apical lobes with strong, ventroapical emargination ( Fig. 28 , Fig. 53 : arrow III ); in ventral and dorsal view, apical lobes more slender, more parallel towards each other, less curved apicomediad and with subtruncate ends ( Fig. 54 : arrow V , Fig. 55 ); dorsal lobe, in lateral view, with narrow apex ( Fig. 28 , Fig. 53 : arrow IV ). Female: Sperm pump as in Fig. 147 ; bursa membranous. Distribution: Scopaeus batukaruensis is distributed in the Lesser Sunda Islands Bali and Lombok. Etymology: With the epithet batukaruensis (adjective, Latin, composed of the geographic name Batukaru and the suffix – ensis , which indicates the geographical origin) reference is made to Mount Batukaru in Bali , where most of the type specimens were collected.
