Type locality. Originally described from ‘a specimen from Silago and another from the District of Rawas’ ( JACOBY 1884).According to the present lectotype designation, the type locality is restricted to ‘District of Rawas’ [= subregion Musi Rawas, South Sumatra, Indonesia].

Type material. LECTOTYPE (designated here): ♀, ‘Rawas / 5.78 [grey label, h] // Mimastra / sumatrensis / Jac. [blue label, h]’ ( RMNH). The lectotype is provided with one red printed label: ‘ LECTOTYPUS, / Mimastra sumatren- / sis Jacoby, 1884 / des. J. Bezděk 2008’.

PERAK: 1 spec. unsexed, Cameron Highlands, Ringlet , 40 km SE of Ipoh, 4°25´N 101°23´E, 900 m, 25.iv.–5.v.2001, M. Říha leg. ( JBBC) ; 2 spec. unsexed, Cameron Highlands , 30 km E of Taqah, 650 m, 22.–26.iii.2004, without the name of collector ( JBBC) . INDONESIA: SUMATRA: 1 spec. unsexed, Riau prov., Bukit Tigapuluh N. P., 0°50´S 102°26´E, 18.–25.i.2000, J. Bezděk leg. ( JBBC) ; 12 spec. unsexed, Lampung prov., Bukit Barisan Selatan N. P., 5 km SW of Liwa , 5°4´S 104°4´E ; 600 m, 7.–17.ii.2000, J. Bezděk leg. ( JBBC) .

Differential diagnosis. Mimastra sumatrensis can be easily distinguished from its congeners by the uniformly yellow body and the shape of the pronotum, which is widest at the anterior corners, slightly convergent posteriad and twice as long as broad. Mimastra pallida has similar coloration but is usually much smaller in size. Aedeagus as in Fig. 18 . Spermatheca as in Fig. 15 . Body length: males 8.00– 8.85 mm; females 7.75–9.75 mm (lectotype 7.75 mm).

Distribution. Indonesia: Sumatra ( JACOBY 1896b), Kalimantan ( REID 1997); Malaysia: Pahang, Perak ( MOHAMEDSAID 1992, present paper), Negeri Sembilan, Selangor ( MOHAMEDSAID 1992), Sarawak ( MOHAMEDSAID 1997, 1998b, 1999b), Sabah ( MOHAMEDSAID 1999a, 2000).

Comments. The original description of M. sumatrensis was based on two specimens ( JACOBY 1884). I have found only one of them (female) in RMNH and designate it as the lectotype. The deposition of the second type specimen is unknown to me.

A colour photo of an unsexed specimen, allegedly a type, and its labels deposited in MCZ is available online at: http://mcz-28168.oeb.harvard.edu/mcztypedb.htm. The specimen was collected in Sumatra, Pangherang-Pisang. However, Jacoby examined specimens from Pangherang-Pisang only several years after the description (JACOBY 1896). Therefore, this specimen cannot be treated as part of the type series of M. sumatrensis .
