description: <i>Paedophryne kathismaphlox</i> sp. n. urn:lsid:zoobank.org:act: 3B527D14-119D-4190-8A76-0FAD5D3A0B7D Figs 1, 2, 3G, H, I, 5, 7 <b>Holotype.</b> BPBM 17977 (field tag FK 7471), adult female, collected by local villagers on NE slope Mt. Simpson, 10.03157°S, 149.57667, 2170 m, Milne Bay Province, Papua New Guinea, 21 February 2003. <b>Paratypes (n = 3).</b> BPBM 17975, 35353, same data as holotype, except collected 19 February 2003; BPBM 17976, same data as holotype. <b>Diagnosis.</b> A minute microhylid (male SV = 10.1 mm, female SV = 10.4–10.9 mm) with the features of the genus and a relatively short leg (TL/SV = 0.35–0.39, Fig. 4A); short snout (EN/SV = 0.067 –0.079, EN/IN = 0.78–0.80, Fig. 4C); mediumsized eye (EY/SV = 0.12, EY/SN = 0.92–1.00, Fig. 4C); dorsal pattern of small darkbrown blotches on a dark-brown ground (Fig. 4A); ventral pattern of tiny, scattered light straw flecks on a dark-brown ground (fig 4B); and a burnt-orange patch (in life) below the anus that contrasts with the dark-brown on the remainder of the animal. <b>Comparisons with other species.</b> Th e new species differs from other asterophryines in the characters that typify the genus and in its unique burnt-orange rump patch. <b>Description of holotype.</b> An adult female with a small mid-ventral incision. Head moderately wide (HW/SV = 0.35, Fig. 4A), with steeply oblique loreal region; canthus rostralis rounded, slightly convex when viewed from above; nostrils directed anterolaterally, closer to tip of snout than to eyes; internarial distance larger than distance from naris to eye (EN/IN = 0.80, IN/SV = 0.095, EN/SV = 0.076); snout rounded when viewed from the side or from above (Fig. 4A, C); eyes moderately large (EY/SV = 0.12; EY/SN = 0.93, Fig. 4C), pupil horizontal; eyelid more than half width of interorbital distance; tympanum indistinct and small (TY/SV = 0.057), visible only when skin dries slightly. Skin smooth; supratympanic fold absent. Fingers unwebbed, flattened; F1 very reduced in size; relative lengths 3&gt;2=4&gt;1 (Fig. 4D). Disc present only on F3, not wider than penultimate phalanx, circum-marginal groove absent. Subarticular and metacarpal tubercles absent. Toes unwebbed; T2, T3, and T4 with flattened discs, but only T4 has a terminal groove. Fifth toe reduced in size, with round tip and no disc; T1 a vestigial nub; relative lengths of toes 4&gt;3&gt;2=5&gt;1 (Fig. 4E). Toe discs barely wider than finger disc (3 rdF /4 thT = 0.85); disc of fourth toe not wider than penultimate phalanx. Subarticular and metatarsal tubercles absent. Hind legs rather short (TL/SV = 0.39, Fig. 4A). Tongue elongate, straplike, anterior third attached to floor of mouth. <b>Table |.</b> Features diagnosing <i>Paedophryne</i> gen. n. from its most similar-appearing relatives. Features given for <i>Cophixalus</i> exclude mention of uncommon variants discussed in the text. In preservative, dorsum medium brown, irregularly and vaguely marked with darker brown, but pattern indistinct (Fig. 4A); darker markings somewhat more obvious on limbs. Face and behind eye brown spotted with light straw brown (Fig. 4C). Venter and under legs dark brown with scattered light straw-brown flecks; rear of thighs same (Fig. 4B). Dirty gray-white patch below anus and proximal portion of thighs (Fig. 4B). Iris black.
