Mimastra pallida Jacoby, 1896

( Figs. 8 , 10 , 26 )

Mimastra pallida Jacoby, 1896a: 139 (original description).

Mimastra pallida: JACOBY (1897) : 408; WILCOX (1973): 484 (catalogue); KIMOTO (1990): 208; MOHAMEDSAID (1992): 116 (key); MOHAMEDSAID (2000): 351; MOHAMEDSAID (2004): 98 (catalogue).

Mimastra (Mimastra) pallida: WEISE (1924) : 125 (catalogue).

Type locality. ‘Si-Oban, also Borneo’ ( JACOBY 1896a). Due to the present lectotype designation, the type locality is restricted to ‘Si-Oban’ [= Sioban, 2°10′S 99°43′E, Sipora Island, Sumatra, Indonesia].

Type material examined. LECTOTYPE (designated here): J, ‘ Mentawei / Si Oban IV-VIII / Modigliani 94 [w, p] // Typus [w, red letters, p] // pallida / Jac. [w, p] // Mimastra / pallida / Jac. [blue label, h] // Museo Civico / di Genova [w, p]’ ( MSNG) . PARALECTOTYPES: 1 J, 1 spec. unsexed, ‘ Mentawei / Si Oban IV –VIII / Modigliani 94 [w, p] // Teste / Jacoby [yellow label, p] // Museo Civico / di Genova [w, p]’ ( MSNG) ; 2 spec. unsexed, ‘ Mentawei / Si Oban IV –VIII / Modigliani 94 [w, p] // Museo Civico / di Genova [w, p]’ ( MSNG) ; 1 spec. unsexed, ‘ Mentawei / Si Oban IV –VIII / Modigliani 94 [w, p] // 163 [pale green label, p] // Mimastra / pallida / n. sp. Jac. [white label with vertical red stripe, h] // Museo Civico / di Genova [w, p]’ ( MSNG) ; 1 spec. unsexed, ‘Co- / type [round white with yellow collar, p] // Mentawei / Si Oban IV –VIII / Modigliani 94 [w, p] // Museo Civ. / Genova [orange label, p] // Jacoby Coll. / 1909-28a [w, p] // Mimastra / pallida / Jac. [blue label, h]’ ( BMNH). A colour photo of one paralectotype (unsexed) and its labels deposited in MCZ is available online at: http://mcz-28168.oeb.harvard.edu/mcztypedb.htm. The specimen bears the following labels: ‘ Mentawei / Si Oban IV –VIII / Modigliani 94 [w, p] // 211 [grey label, p] // Mimastra / pallida / n. sp. Jac. [w, h] // Type [p] 18178 [red label, h]’. All specimens examined (except the one from MCZ) are provided with a red printed label : ‘ LECTOTYPUS [or PARALECTOTYPUS], / Mimastra pallida / Jacoby, 1896 / des. J. Bezděk 2008’.

Additional material examined. INDONESIA: SUMATRA: 1 spec. unsexed, Sipora Is., Sereinu, v–vi.1894, Modigliani leg. ( BMNH) ; 1 J 2 ♀♀ 2 spec. unsexed, Batu Is., 1896–1897, H. Raap leg. ( MSNG) . MALAYSIA: PAHANG: 1 J 1 ♀, Cameron Highlands, Tanah Rata , 35 km SEE of Ipoh, 4°28´N 101°23´E, 1500 m, 21.–24.iv.2001, M. Říha leg. ( JBBC) .

Differential diagnosis. Dorsal side yellow, ventral side usually completely yellow, but in two paralectotypes with infuscate metasternum and abdomen. Legs yellow, femora with a black stripe on the outer side near apex, middle and hind tibiae more or less darkened. This species resembles M. sumatrensis by the yellow dorsum, but is smaller in size and the aedeagi of both species are completely different ( Figs. 10 , 18 ). Spermatheca as in Fig. 8 . Body length: males 4.85–5.95 mm (lectotype 5.00 mm); females 5.85–6.00 mm.

Distribution. Indonesia: Sipora Is. (JACOBY 1896) and Batu Is. ( JACOBY 1897); ‘Borneo’ (JACOBY 1896); Malaysia: Sabah ( MOHAMEDSAID 2000) and Pahang (present paper).

Comments. JACOBY (1896a) did not specify the number of type specimens. The main part of the type series (six specimens) is deposited in MSNG and one additional specimen is found in BMNH and MCZ each. One male from MSNG is designated here as the lectotype.

Two specimens from Malaysia, Pahang, identified as M. pallida have more slender and longer tarsomeres but the aedeagus is almost identical with the males from the type series.
