Referred specimens. Papua New Guinea: Milne Bay Province: Sudest Island: along Gesirava River, W slope Mt. Riu, 11.49179ºS, 153.41261ºE, 127 m ( BPBM 19742); W slope Mt. Riu, 11.49610° S, 153.42413° E, 410 m ( BPBM 19743); W slope Mt. Riu, 11.486413ºS, 153.4148351ºE ( BPBM 19744); Rewa ( MCZ 156549).

Diagnosis. A large (SV = 116–133 mm) species of Cyrtodactylus having a single row of enlarged subcaudals; enlarged dorsal tubercles flat, unkeeled, 2–3 times size of adjacent granules ( Fig. 2 C), in 27–32 rows; lateral tubercles indistinct, ~2–3 times size of adjacent granules and approximately same size as scales of lateral skin fold; 34–39 midbelly scale rows; precloacal/femoral pores 69, in a single continuous row; lamellae under fourth toe 24–26; head of moderate width (HW/HL = 0.67–0.72, mean 0.69); four dark dorsal bands between head and hindlimb insertion, of even width, typically not well margined in black, with 8–13 tubercles sagitally through 3rd dark band; dark spots absent from light dorsal ground color; mouth and cloacal linings pink; ventral scales dirty white clouded with brown; and posterior supralabials brown.

Comparisons with other species. Cyrtodactylus louisiadensis is distinguished from all other Australo- Papuan members of the genus except C. aaroni , C. mimikanus , C. murua , C. tuberculatus , and C. salomonensis by its single row of enlarged subcaudals. From C. aaroni and C. mimikanus it is distinguished by its larger size (SV = 116–133 mm vs. 70–86.5 mm in C. aaroni and 67–103 in C. mimikanus ), greater number of precloacal/femoral pores (69 vs. 17–27 in C. aaroni and <40 in C. mimikanus ) in a single series (vs. three discrete patches), and fewer dark dorsal bands between the head and hindlimbs (4 vs. 8–11 in C. aaroni and C. mimikanus ). From C. murua it is distinguished by having a greater number of dorsal tubercles (27–32 rows vs. 20– 22 rows in C. murua ); dorsal tubercles flat (vs. conical in C. murua ); and dorsal bands narrower than or of equal depth to intervening ground color (vs. wider in C. murua ), of even width across dorsum (vs. broadening medially in C. murua ), and with straight margins (vs. irregular margins in C. murua ). From C. tuberculatus it is distinguished by its larger size (SV = 116–133 mm vs. 80–89 mm in C. tuberculatus ), greater number of midbelly scale rows (34–39 vs. 27–36 in C. tuberculatus ), greater number of precloacal/femoral pores (69 vs. 36–46 in C. tuberculatus ), and by having fewer dark dorsal bands (4 vs. 6–7 in C. tuberculatus ) that are unmargined or poorly margined in black. From C. salomonensis it is distinguished by having no conspicuously enlarged tubercles (vs. having series of enlarged tubercles) along the lateral skin fold, fewer 4th toe lamellae (24-26 vs. 28–31 in C. salomonensis ), and fewer dark dorsal bands (4 vs. 6–7 in C. salomonensis ) having even (vs. irregular in C. salomonensis ) margins.

Cyrtodactylus louisiadensis is unique among members of this complex in having small, flat tubercles that are not elevated above the surrounding granules and shares with only one other species (following) brown posterior supralabials.

Description of neotype: A mature female, with two large eggs, and lateral incision. Animal large (SV = 127 mm, TrL = 58.2 mm); tail folded back on itself and unamenable to accurate measurement, approximately as long as SV. Head relatively long (HL/SV = 0.29) and wide (HW/HL = 0.67), not depressed (HH/HL = 0.40), distinct from neck. Loreal region slightly inflated; canthus rostralis poorly defined. Interorbital region and top of snout concave. Snout relatively long (SN/HL = 0.39), much longer than eye diameter (SN/EY = 1.8). Eye relatively large (EY/HL = 0.22); pupil vertical, with weakly crenellated margins; supraciliaries large, frill-like, well-differentiated from adjacent granules. Ear opening small (Ear/HL = 0.073), somewhat depressed; distance between ear and eye larger than eye diameter. Rostral wider (5.9 mm) than high (3.2 mm), highest just medial to nares, lower between these points; length 2.8 mm; dorsal half divided by weak medial groove. Two enlarged supranasals separated by single internasal. Rostral in contact with first supralabials, two supranasals, and one internasal. External nares circular; each bordered by rostral, supranasal, first supralabial, and nasal. Nasal bordered posteriorly by five (right) or six (left) small granular scales. Four rows of small scales separate orbit from supralabials at narrowest point. Mental shallowly triangular, wider (5.2 mm) than long (3.4 mm). Mental bordered posteriorly by two enlarged postmentals. First four infralabials bordered by enlarged, elongate scales; fifth infralabial bordered on anterior third by same; these followed posteriorly by tiny granules. Supralabials to mid-orbital position eight on right side, nine on left; to angle of jaw 13 on right, 14 on left. Infralabials nine on right, ten on left.

Body moderately robust (TrL/SV = 0.46), with poorly developed lateral skin folds consisting of slightly enlarged scales approximately same size as adjacent ventral scales and lateral tubercles. Dorsal scales on head, body, and limbs tiny, juxtaposed granules, each with small raised asperities. Small, flat tubercles present on head, body, and limbs; best developed posteriorly; 2–3 times size of adjacent granules; not distinct from granules in profile. Dorsal tubercles with one weak keel; those on head, limbs, and sides of body unkeeled. Tubercles arranged in approximately 32 poorly defined rows between the lateral folds. Ventral scales flat and smooth; those on chin and throat smaller and juxtaposed; those on abdomen larger and subimbricate, arrayed in 39 rows across mid-venter.

Precloacal and femoral pores absent. Scales of precloacal and femoral regions of approximately uniform size and not distinct from those on abdomen; scales on posterior femoral region smaller, one-third to one-half size of precloacal scales. No precloacal groove. Scales on palms and soles rounded, smooth.

Fore- and hindlimbs relatively well-developed (FA/SV = 0.13, CS/SV = 0.16). Digits well-developed, reflected at basal interphalangeal joints; all with robust, recurved claws surrounded by two scales. Subdigital lamellae narrow and smooth, expanded proximally. Lamellae of manus 18–22–21–23–19 on right, 18–20–22– 22–20 on left; of pes 17–21–22–25–21 on right, 17–21–23–25–20 on left. Relative lengths of digits on manus I <V <II <III <IV; on pes I <II <V <III <IV. No interdigital webbing on manus, slight webbing on pes.

Tail complete, with rather narrow base (TW/SV = 0.058), tapering to a blunt point, with single row of enlarged subcaudals until distal ~ 2 cm. Cloacal sacs small, with small external orifices situated near lateral margins of vent; midventral scales of sac distinctly larger than those ventrolaterally. Scales of tail small, flat, smooth, subimbricate; with approximately six rows of enlarged dorsal tubercles just behind cloacal sacs but disappearing after first light ring on tail; three (left) or four (right) small, flat postcloacal spurs on sides of tailbase.

Color in preservative: Dorsal ground color medium sienna brown; slightly darker sienna brown chevron on nape whose anterior arms enter posterior border of eye; three more dark sienna brown bands to region between hindlimbs; five more on tail, with last tail band faint and the three middle bands darkest and most distinct. Dark dorsal bands of approximately even width across dorsum. No light margins to dark dorsal bands; faint indication of narrow dark margining on third dorsal band but not on remainder. Tubercles same color as surrounding granules. Labials brown, not contrasting with face. Venter with dirty white ground color but largely suffused with same medium brown color as dorsal ground. Palms and soles light gray suffused with some brown color.

Measurements (in mm). SV = 127, TrL = 58.2, TW = 7.4, FA = 17.0, CS = 20.3, HL = 36.8, HW = 24.5, HH = 14.8, Ear = 2.7, EE = 11.0, EY = 8.0, SN = 14.2, EN = 11.0, IN = 5.2, IO = 8.1.

Color in life. A color photo of BPBM 19742 ( Fig. 1 A) indicates the dorsal ground color to be a medium sienna brown, with four slightly darker sienna dorsal bands that lack dark or light margins to set them off from the ground color. Second and third light bands on tail medium tan; last dark band charcoal gray. Iris rich reddish brown.

Variation. All four adult specimens are females and range in size from 116–133 mm SV; the sole juvenile is a 64 mm male. Mensural data for the five known specimens of this species are given in Table 1 . Supralabials to center of eye vary from 8–11, to angle of jaw 13–16. Infralabials vary from 9–11, fourth toe lamellae 24–26, mid-belly scale rows 34–39, and number of rows of dorsal tubercles 27–32.

Color pattern uniformly includes four dark dorsal bands (including the nuchal chevron), which typically lack or have poorly developed black margins and contrast relatively little with the slightly lighter ground color. Ground color varies slightly among the four available recent specimens, with one having a dark tan ground color that contrasts better with the dark bands than what is seen in the neotype. Another has somewhat darker sienna ground color, providing less contrast with the dark bands than seen in the neotype. One specimen (BPBM 19744) has dark margins moderately well developed along the dark dorsal bands. All have brown labials.

Range. Known only from Sudest Island, Milne Bay Province, Papua New Guinea ( Fig. 3 , star).

Ecology. Most of my specimens came from primary lowland rainforest in the vicinity of a small river at 130 m elevation, although one came from primary rainforest on a ridge at 400 m elevation. One specimen was collected in a drift-fence bucket set at the first locality. It occurred syntopically with the next described species as well as with the geckos Gehyra oceanica (Lesson) and two undescribed species of Nactus . It likely occurs as well with Gehyra mutilata (Wiegmann) , G. v o r a x Girard, Gekko vittatus Houttuyn , Lepidodactylus lugubris (Duméril and Bibron) , L. orientalis Brown and Parker , and Nactus sphaerodactylodes Kraus , which were found in forested situations elsewhere on Sudest.

Remarks. In his original description of the sole specimen of Gymnodactylus louisiadensis , de Vis (1892a) mentioned three features useful for deciding which of the two Sudest species he had in hand. His specimen possessed (1) small, smooth tubercles arrayed in (2) 26 dorsal rows, and it had (3) five dark dorsal bands. Of these features, the first two accord with the species I have chosen to represent C. louisiadensis . In my limited sample, though, all specimens have only four dark dorsal bands between the head and tail, not five. It might be thought possible that de Vis was including an additional dark band on the tail anterior to a regenerated (and, hence, unbanded) tail, but this seems unlikely inasmuch as de Vis specifically referred to black rings on the base of the tail and the fact that the intervals between caudal bands and the terminal part of the tail were white. Hence, I conclude that numbers of dark bands may be variable within this species and that de Vis had a colorpattern phenotype not included in my limited sample. Arguing in favor of my allocation of C. louisiadensis to the chosen species is the fact that it is the only member of the complex to have small, smooth dorsal tubercles and the number of rows of these tubercles in the lost holotype more closely matches this species (range = 27– 32 in my sample) than its sympatric congener (range = 20–23), whose description follows.

The text usually cited as the original description of Gymnodactylus louisiadensis is that cited here as de Vis (1892b). However, in the introduction to that article, de Vis states that it consists of the substance of a prior report cited here as de Vis (1892a). The two are verbatim copies except that four short and irrelevant introductory paragraphs found in de Vis (1892a) were omitted from de Vis (1892b).

Beyond noting that the specimen came from Sudest Island, de Vis provided no other information on the specimen’s provenance. MacGregor (1892) made clear that the material reported on by de Vis was obtained by Mr. Charles Hedley, then employed at the Queensland Museum, who engaged in a collecting trip to British New Guinea from May to August, 1890 ( Hedley, 1891). Hedley himself makes clear in his report on land snails ( Hedley, 1891) that he did not collect on Sudest but relied on the services of Messrs. Kowald and Belford, whom MacGregor directed to assist Hedley. The only trip taken to Sudest Island by government officials during Hedley’s sojourn in New Guinea occurred July 8–9, with their ship leaving that island and anchoring at Rossel Island on July 10 ( MacGregor, 1892). While on Sudest, MacGregor’s ship was anchored at Tagula, on the western end of the island, although he and his staff roamed over much of the western third of that island. Hence, the provenance of the type specimen was likely the western end of Sudest and collected on the night of either 8 or 9 July 1890.

Color pattern uniformly includes five dark dorsal bands (including the nuchal chevron), all of which have black edges that are further margined in light tan. These dark bands contrast moderately well with the somewhat lighter ground color. The two recently collected specimens differ in no important degree in color pattern or shading. Both have brown labials.

Etymology. The trivial epithet is named for Arnold Kluge in recognition of his many contributions to gekkonid systematics.

Range. Known only from Sudest Island, Milne Bay Province, Papua New Guinea ( Fig. 3 , star).

Ecology. This species was found in primary lowland rainforest along a small river at 130 m elevation. It occurred syntopically with the geckos Cyrtodactylus louisiadensis , Gehyra oceanica and two undescribed species of Nactus . It likely occurs with Gehyra mutilata , G. v o r a x, Gekko vittatus , Lepidodactylus lugubris , L. orientalis , and Nactus sphaerodactylodes , which were found in forested situations elsewhere on Sudest.
