Neolepta quadriplagiata Jacoby, 1886: 99–100

Type material. — Lectotype: “ Sumatra Mt. Singgalang, Luglio 1878. O. Beccari / Neolepta 4plagiata Jac.” ( MCGD; Fig. 15 View Fig ). Type locality: Indonesia, Singgalang , 0°24'S / 100°21'E GoogleMaps . Paralectotypes: 3 ex., same data as lectotype ( MCGD) GoogleMaps ; 1 ex., additionally with “1st Jacoby coll. / Type 18314” ( MCZH). Jacoby gave no number on the specimens he studied, and we herein designate a lectotype to fix the name on single specimen .

Total length. — 5.00– 5.25 mm (mean: 5.11 mm, n = 8)

Head. — Reddish-brown, impunctate. First and second basal antennomeres contrasting brown-reddish, third to outer antennomeres black ( Figs. 10 View Figs , 15 View Fig ). Ratio length of second to third antennomeres 0.75–0.88 (mean: 0.79); median to terminal antennomeres are slender, ratio length of third to fourth antennomere 0.40–0.44 (mean: 0.41; Fig. 11 View Figs ).

Thorax. — Pronotum reddish-brown. Pronotal width 1.30– 1.45 mm (mean: 1.40 mm), ratio length to width 0.59–0.62 (mean: 0.61). Elytra black at base, a broad yellowish spot occupies the anterior half of the disc, extending nearly to either the outer margin, the anterior edge of this spot is obliquely rounded near the suture, another smaller and triangular spot is placed near the apex of each elytron ( Figs. 10 View Figs , 15 View Fig ). Elytral length 4.00– 4.25 mm (mean: 4.15 mm), maximal width of both elytra together 2.60–3.00 mm (mean: 2.84 mm), ratio of maximal width of both elytra together to length of elytra 0.63–0.70 (mean: 0.68). Coxa and femur reddish-brown, tibia and tarsus black.

Abdomen. — Pale yellow to reddish brown.

Male genitalia. — Median lobe not incised, apex carinated ventrally in the middle. Tectum narrow, became pointed at apex. Endophallus consists of only median spiculae; long, slender and straight. Stronger sclerotized ventral spur with apical hook occurred at the apical first of the median lobe. Several basal endophallus structure at the bottom, close to sacculus ( Fig. 12 View Figs ).

Female genitalia. — Like description of the genus ( Figs. 13, 14 View Figs ).

Diagnosis. — Median antennomeres of N. quadriplagiata are rather slender while N. sumatrensis are insignificantly

widened. The median lobe of N. quadriplagiata ( Fig. 12 View Figs ) is quite similar to N. sumatrensis , but the latter has a broadened tectum ( Fig. 4 View Figs ). Elytron always with two yellowish spots.
