Toxicocalamus mintoni — O’SHEA et al. 2015
|Distribution||Papua New Guinea|
Type locality: ridge on W slope of Mt. Rio, 11.49610° S, 153.42413° E, 410 m elevation, Sudest Island, Milne Bay Province, Papua New Guinea.
|Types||Holotype: BPBM 20822 (field tag FK 9717), adult male, collected by J. Slapcinsky, on 21 April 2004.|
|Diagnosis||Diagnosis. A moderately sized species of Toxicocalamus having 15 scale rows, 194 ventrals, preocular fused with prefrontal (Fig. 1A), frontal fused with supraoculars (Fig. 1B), internasal unfused with prefrontal, temporal scales unfused with supralabials, six supralabials, divided anal plate, paired subcaudals, uniformly light brown dorsum, and an unpatterned, light-brown venter. Toxicocalamus mintoni sp. nov. may be distinguished from T. grandis, T. holopelturus, T. loriae, and T. spilolepidotus in having the preocular fused with the prefrontal (vs. unfused); from T. buergersi and T. preussi in having the internasal unfused to the prefrontal and the temporal unfused to the last supralabial; from T. stanleyanus in having a divided (vs. single) anal plate, six (vs. five) supralabials, and unpatterned (vs. spotted) venter; from T. longissimus in having 15 (vs. 17) dorsal scale rows, an unpatterned (vs. striped) venter, and far fewer ventrals (194 vs. 262–273); and from T. misimae in having fewer ventrals (194 vs. 223–231), an unpatterned (vs. striped) venter, and brown (vs. gray) dorsum. Toxicocalamus mintoni sp. nov. differs from all other members of the genus in having the frontal fused with the supraoculars. Further, among the six members of the genus having the preocular fused with the prefrontal it is the only one to have normal-sized ventral scales (vs. narrow ventrals only 3–4 times the size of first scale row).|
