( Figs 1 B, 2A–I, 3A–D) Pythamus melichari var. Borneensis Baker , 1923 : 368; pl. 1, fig. 1b; pl. 2, fig. 15. Body length: male 6.3–6.5mm ; female: 6.9–7.3 mm . Head ( Figs 1 B, 2A, B) with vertex nearly entirely dark brown except subapical narrow band and spot next to eyes, yellow; face ( Fig. 2 C) yellow except gena with narrow dark brown band next to eye and postclypeus variably marked with dark brown dorsally ( Fig. 1 B). Pronotum ( Figs 2 A, B) dark brown dorsally and laterally to beyond lateral carina. Forewing ( Figs 1 B, 2D) dark brown with narrow hyaline band on basal two-thirds of costal margin. Male pygofer process ( Fig. 2 E) with several mainly truncate teeth over distal half. Style ( Fig. 2 G, H) with lateral apical process relatively long. Aedeagus ( Fig. 2 F, G, H) with ventral keel arising near base with lower margin concave, relatively broad in lateral view, thereafter shaft laterally compressed with apex tubular and incised in dorsal view with small ventral subapical medial process. Material examined. Lectotype ♂ (here designated, Fig. 1 B), 1♂ , 2♀♀ paralectotypes : Sabah, “Sandakan, Borneo, Baker ” ( NMNH ). 1♀, Sabah, Sandakan, 30-vii-1927 , ex. F.M.S., B.M. 1955-354; 1♀, Sarawak , foot of Mt. Dulit, Junction of Rivers Tinjar & Lejok, 2-ix-1932 , Oxford Univ. exp., light trap, B.M. Hobby & A.W. Moore, B.M. 1933-254 (both BMNH ). 1 ♂ , Sarawak , Bidi, 3.ix.1958 , secondary forest, T.C. Maa ( BPBM ) Distribution. Sarawak , Sabah. Remarks. This species was originally described from an unknown number of specimens from ‘Borneo, Sandakan ( Baker ). It can be distinguished from other species of the genus by the more extensive dark brown markings and shape of the male genitalia (see above). Its distribution overlaps with P . bilobatus in Sandakan. FIGURE 1. Habitus of Pythochandra species (types). A, P. bilobatus (female). B, P. borneensis (male). C, P. melichari (male).

Vertex ( Figs 1 C, 4A, B) with spot at tip and at posterior corner and a transverse band medially not extending to posterior margin but sometimes extending to spot at posterior corner, dark brown; frontoclypeus ( Fig. 4 C) with dark brown spot next to antennal socket. Pronotum ( Fig. 4 A, B) dark brown with lateral margin yellow. Forewing dark brown on clavus and adjacent area of corium. Male pygofer process ( Fig. 4 H) with few acute teeth subapically. Aedeagus ( Fig. 4 I, J. L) with ventral keel at mid length of shaft, relatively narrow in lateral view, thereafter shaft tubular without processes. Material examined. Lectotype ♂ (here designated, Fig. 1 C), 1 ♂ , 1♀ paralectotypes : Philippines , “P. [Puerto] Princesa, Palawan, Baker ” ( NMNH ). 1♀, Philippines , Laguna, Los Banos, x–xi.1915 , F. Muir ( BPBM ). Distribution. Philippines : Palawan Island and Laguna. Remarks. This species was originally described from an unknown number of specimens from “ Philippines ”. It can be distinguished from other species of the genus by the vertex with central dark brown band slightly reduced in size and by the shape of ventral process of the pygofer and shape of the aedeagus.
