scientific name

Paraneolepta imitans ( Jacoby, 1894 )
status

comb. nov.

Paraneolepta imitans ( Jacoby, 1894) , new combination

( Figs. 31–36 View Figs View Fig )

Ochralea imitans Jacoby, 1894: 321

Monolepta aemula Weise, 1922: 107 ; new synonym

Remarks. — Monolepta aemula is a replacement name. Weise (1922) transferred the species to Monolepta and named it new to avoid the homonymy with Monolepta imitans Jacoby, 1888 from Central America.

Type material. — Lectotype, female, “Type H. T / Perak / Ochralea imitans Jac. / Jacoby coll. 1909-28a,” ( BMNH; Fig.36 View Fig ). Type locality: Malaysia, Perak, 4°48'N / 101°09'E. Jacoby gave no number on the specimens he studied, but there must be more than one concerning the original description, and we herein designate a lectotype to fix the name on single specimen.

Total length. — 6.65–8.00 mm (mean: 7.03 mm; n = 10)

Head. — Reddish-brown, impunctate. Antennae entirely black and only the first basal antennomeres usually contrasting reddish-brown ( Fig. 31 View Figs ). Ratio length of second to third antennomere 0.80–0.83 (mean: 0.81); ratio length of third to fourth antennomere 0.42–0.46 (mean: 0.44; Fig. 32 View Figs ).

Thorax. — Pronotum reddish-brown, coarsely punctuated. Pronotal width 1.80–2.25 mm (mean: 1.98 mm), ratio length to width 0.60–0.63 (mean: 0.61). Scutellum black. Elytra entirely yellow to brown, sutural and lateral margin narrowly black. Elytral length 5.00– 6.25 mm (mean: 5.51 mm), maximal width of both elytra together 3.60–4.50 mm (mean: 3.95 mm), ratio of maximal width of both elytra together to length of elytra 0.69–0.74 (mean: 0.72). Legs yellow to brown, black line along dorsal part of femur, tibiae and tarsi blackish.

Abdomen. — Yellow to pale brown.

Male genitalia. — Median lobe insignificantly narrowed towards apex, where it is blunt ( Fig. 33a View Figs ). Tectum parallelsided, with short, pointed tip, much shorter than the ventral part ( Fig. 33b View Figs ).

Female genitalia. — Spermatheca like description of the genus ( Fig. 34 View Figs ), two pairs of bursa sclerites like Fig. 35 View Figs .

Distribution. — Recorded from Peninsular Malaysia, Borneo and Sumatra ( Fig. 22 View Fig ).

Diagnosis. — The body size and colouration of P. imitans is most similar to P. limbella . The differences on both species can be obtained clearly by median lobe and bursa sclerites. The tectum of median lobe of P. limbella is shorter and narrowed towards the pointed tip ( Fig. 27 View Figs ) while in P. imitans is broader at base, and pointed at the tip of it ( Fig. 33 View Figs ). Two pairs of bursa sclerites present in P. imitans ( Fig. 35 View Figs ) and only one pair of bursa sclerites in P. limbella ( Fig. 29 View Figs ).
