Type species: Lampyris praeusta Eschscholtz 1822 , designated by Motschulsky (1853).
Diagnosis. Colophotia is a S. E. Asian genus with a dense concentration of species in the Philippines. All but one are pale brownish or yellow dorsally usually with black elytral apices, and larvae are terrestrial. Species are never seen in high numbers, usually being taken singly when their flashing pattern is observed (Jusoh, Wong pers. comm.).
Colophotia belongs to a group of nine Luciolinae genera (the others being Australoluciola Ballantyne , Emarginata gen. nov., Inflata Boontop , Medeopteryx Ballantyne , Pteroptyx Olivier , Pyrophanes Olivier , Serratia gen. nov. and Trisinuata Ballantyne ) all of which have pronotal width less than width across the elytral humeri; parallel-sided elytra; aedeagal sheath elongate slender, widest across the middle, with each side of the posterior half of sternite tapering evenly towards a narrow entire apex. With the exception of Inflata Boontop , males of these genera are also characterized by: an elongate slender aedeagus with LL concealed behind the ML (when the specimen is viewed from beneath); the aedeagus of Inflata has a ML swollen in the middle and apically acute LL visible at their bases only from below). Colophotia males are distinguished from all other genera by a combination of the following characters:
1. an elongate slender aedeagus which is often 5 times as long as wide, or longer
2. the aedeagal LL are very short and scarcely separated along their median dorsal length (b/a is approximately 0.3)
3. an elongate slender aedeagal sheath which may be up to 7 times as long as wide
4. accommodating the elongate aedeagus and sheath, the paired anterolateral arms of T8 are longer than the posterior entire portion of T8
5. the anterolateral corners of T7 are prolonged (presumably to provide extra surface area for muscle attachment from the very elongated aedeagal sheath)
6. bipartite LO in V7 has an elongate median carina between the LO halves
7. antennal FS 7–9 are shorter than the remaining FS and FS 9 is usually apically acute
8. there is no MFC, no deflexed elytral apices, and no leg segments are swollen or curved or emarginated
9. the posterior margin of V7 is trilobed, with well-defined and oblique to vertical PLP, and a well-defined and often very large MPP which is apically emarginated, may be grooved along its median ventral length, and is prolonged into dorsally curving hooks.
Females are macropterous and the bursa in species investigated has wide paired plates. Larvae lack laterally explanate tergal margins, the laterotergites are clearly visible from above, and are very similar to described larvae of Pteroptyx spp.
Redescription of Male. Pronotum: not much wider than long; dorsal surface without irregularities in posterolateral areas (1) and longitudinal groove in lateral areas (2); punctation moderately dense (3); anterior margin not explanate (6); lateral margins diverging posteriorly along most of their length (C>A, B); width <humeral width; anterolateral corners rounded obtuse; lateral margins without indentation at mid-point, and sinuosity in either horizontal or vertical plane (15, 16); without indentation in lateral margin near posterolateral corner, and irregularities at corner (17, 18); posterolateral corners angulate, approximately 90° and inclined at 90° to the median line; posterolateral corners not usually projecting as far as median posterior margin; separated from it by scarce emarginations.

Head: gently depressed between eyes; moderately well exposed in front of pronotum, and capable of partial retraction within prothoracic cavity; eyes with moderate separation beneath at level of posterior margin of mouthpart complex; eyes above labrum moderately to widely separated; frons-vertex junction rounded, without median elevation; posterolateral eye excavation not strongly developed, not visible in resting head position; antennal sockets on head between eyes, not contiguous, always separated by> ASW sometimes>2 ASW; clypeolabral suture present, flexible, not in front of anterior eye margin when head viewed with labrum horizontal; outer edges of labrum reach inner edges of closed mandibles or beyond. Mouthparts: functional; apical labial palpomere flattened, shaped like an elongate slender triangle (widest at base and L 2– 3x W), with inner edge entire, and at least half as long as apical maxillary palpomere. Antennae 11 segmented; length>GHW up to twice GHW; FS1 subequal in length to, or longer than, pedicel; no FS expanded or laterally produced; all FS including FS 1 longer than wide; FS 7–9 shorter than preceding FS and sometimes much darker in colour, with FS 9 apically acute.

V6 with LO present, occupying almost ventrite surface. V7 with LO bipartite, occupying more than half the surface of ventrite, and reaching to sides and into the PLP; LO halves separated in middle, sometimes widely so; this area may appear slightly depressed; between LO halves a longitudinal median carina which may be low wide and rounded along its ventral length, or high narrow and acute; posterior margin of V7 trisinuate with a slightly asymmetrical MPP, apex of which is deeply emarginate, MPP as long as wide or longer than wide (L=W or L>W), at least subequal to or longer than PLP, and wider than PLP; MPP often with a deep median emargination margined laterally by strong ridges, either evenly or unevenly margined; MPP prolonged into paired hooks which incline dorsally but do not engulf T8, and may be asymmetrically inclined; hooks may arise from posterior apices of MPP and are visible from beneath, or from a preapical dorsal area when they are not visible from beneath; PLP well defined, either subequal in length to MPP or shorter, and inclined either obliquely or vertically so from below they appear narrower than the MPP. T8 well sclerotised, symmetrical, visible posterior area widest across median area (margins may appear convex sided); median posterior margin strongly emarginate; posterolateral corners may be strongly prolonged and incline dorsally in pinned specimen; not engulfing posterior margin of V7 nor MPP (133, 134), with well-defined median longitudinal trough margined laterally by well-defined ridges which are prolonged anteriorly into long apically rounded flanges; flanges may incline one to the anterior and the other posterior, or both slightly anteroventrally; concealed anterolateral arms of T8 always longer than visible posterior portion of T8, sometimes almost 3 times as long; not laterally emarginated before their origins, dorsoventral expansions absent, expanded only in horizontal plane; without bifurcation of inner margin and ventrally directed pieces (217); lateral margins of T8 not enfolding sides of V7 (190); T7 with prolonged anterolateral corners.

Larva. (Associated by breeding for C. praeusta and C. brevis only). Terrestrial; elongate, slender spindle shaped ( Ballantyne & Lambkin 2009 fig. 517), of the form of Pteroptyx maipo and several Australian Australoluciola sp. larvae ( Ballantyne & Lambkin 2000; Ballantyne et al. 2011); tergal plates not produced at sides and laterotergites visible from above.
Remarks. Colophotia has been previously characterised in shortened form ( Ballantyne 1968; Ballantyne & McLean 1970; Ballantyne & Lambkin 2013), mainly because it has not been possible to locate all types. However since three species were scored in a matrix that now has over 400 characters of males, females, and larvae ( Ballantyne et al. 2016) we believe sufficient information on several distinctive Colophotia species permits us to attempt a generic redescription, given that we have been able to locate a type series for one, and possible syntypes for another two. Of the seven species listed in Table 12 View TABLE 12 types cannot be located for three. Two species listed by McDermott (1900) viz. C. miranda Olivier , and C. truncata Olivier are treated as species incertae sedis. McDermott’s (1962) incorrect interpretation of the abdomen of C. praeusta was addressed by Ballantyne & Lambkin (2013: 64). We are presently unable to resolve some apparent inconsistencies concerning Luciola lata Olivier 1883: 79 the male of which Olivier appears to have described with a median carina on the last abdominal segment (“ultimo abdominis segment….in medio longitudinaliter carinata” and “dernier segment de l’abdomen…chargé sur son milieus d’une forte carène longitudinale obtuse”). McDermott (1966) synonymised the species with Luciola pallescens Gorham 1880 . From its size lata could well be a male of C. miranda , and both are treated here as species incertae sedis.
Ballantyne & Lambkin (2013) discussed the genus and their reasons for attributing it to Motschulsky. McDermott (1966) had attributed the genus to Dejean as do Bousquet & Bouchard (2013).
