Colophotia bakeri Pic 1924: 712. McDermott 1966: 116.
Type. 3 syntypes, 2 males (Figs 206−208), female (Figs 209, 210). PHILIPPINES. Island of Luzon, Mindanao labelled as follows: 1. Red handwritten label Colophotia bakeri; 2. Handwritten 17136 for males, 17139 for female; printed Surigao Mindanao Baker. Male female (MNHN); male (USNM).
Other specimens examined. PHILIPPINES. Luzon island: N. Luzon, 5–6000 ft., Whitehead ’ 94 male (identified as Colophotia praeusta in Olivier collection box 60 MNHN); Laguna Province (as Ube Laguna) 6 males April 20 1930 RC McGregor (USNM); Mt Makiling Baker 4 males (USNM); Nueva Viscaya Province, Mt Tabuluan RC McGregor male (USNM). Samar Island: Samar Province Baker male (USNM). Mindoro island: Mindoro Province, Lake Naujan Port (Puerto) Galera RC McGregor male (USNM); Calapan November 1925 A Duyag, RC McGregor male (USNM).
Diagnosis. 8.5−9.3 mm long. One of two species having pale dorsal colouration with no dark marks at elytral apices (the other is C. concolor) (Figs 206, 209); head between eyes largely yellow (with a small dark area on the vertex in type); labrum either almost black, or dingy brown darker near clypeolabral suture, or uniformly light brown, or yellow (see Table13); LO halves in V7 widely and evenly separated along their inner ventral margins (width of separation as wide as base of MPP; Figs 211, 212); with a low barely elevated median carina with a round- ed ventral edge; strongly developed MPP which is deeply emarginated and prolonged into long hooks which arise from the dorsal surfaces of the MPP and curve such that they may appear slightly asymmetrical from behind (Figs 211, 212, 215); hooks are visible from behind but not from below (Fig. 217); MPP broad, about 3 x longer than wide, much longer than PLP; with strongly developed median ventral trough which is margined laterally by acute ridges; apices of MPP when viewed from beneath may appear obliquely truncated with the longer edge to the inside; hooks arise from dorsal surface of the apical paired portions of the MPP. T8 (Figs 218−221) lateral margins convex sided; median ventral trough with strong lateral ridges continuing onto the posterolateral corners; flanges well developed, apically rounded inclining anteroventrally (Fig. 221); posterolateral corners acutely prolonged in one male (type MNHN), left side only prolonged in second male (type USNM e.g. Fig. 218), with right side much shorter; posterolateral prolongations of T8 either short, of medium length or long in other males (Table 13). Aedeagal sheath (Fig. 218): 5.3x as long as wide. Aedeagus (Fig. 218): b/a 0.3; LL apices barely separated along their dorsal margins. Not distinguished here from C. concolor Olivier.
Remarks. Ballantyne & Lambkin (2009, 2013) scored the Mt Makiling males as Colophotia concolor. It is highly probable that bakeri is a synonym of concolor. We have been unable to locate reliably identified material of C. concolor.
