DistributionPapua New Guinea (Morobe Province)

Type locality:

Papua New Guinea, Morobe Province, north slope of Mt Strong, Kesemani (7.9372°S, 147.0544°E), 1733 m elevation.  
ReproductionViviparous. Litter size varies between 2–3 (mean 2.5, N = 6). (Slavenko et al. 2021) 
TypesHolotype: BPBM 41149 (field tag AA 21543), adult male, collected by A. Allison, on 25 February 2012.
Paratypes (n = 28): Papua New Guinea: Morobe Province: Mt Strong: Arabuka, 7.9838°S, 147.0458°E (WGS 84), 1965 m a.s.l. (BPBM 41127–35, 41141–48; five males, seven females, five juveniles); Lamgatak Camp [Camp 2], 7.9325°S, 147.0399°E (WGS 84), 2161 m a.s.l. (BPBM 41136–40; two males, one female, two juveniles); same locality as holotype (BPBM 41150–55; three males, two females, one juvenile). 
DiagnosisDiagnosis: A medium-sized species of Lobulia (adult SVL 45.7–60.5 mm), characterized by the unique combination of frontoparietals unfused; supraorbital ridges not pronounced; nuchals 1–2 pairs; paravertebral scales 55–65; mid-body scale rows 34–37; 4th digit on front foot longer than 3rd; subdigital lamellae 20–25 under 4th toe; single supradigital scales 3–5 on 4th toe; mid-dorsum with two rows of large dark brown spots; top of tail base with single row of large dark brown spots; light blue or white dorsolateral stripes absent; flanks dark brown with thin light blue to grey vertical bands; light blue or white lateral stripes absent; uniform coloration on abdomen either lemon yellow (in males) or white (in females) in life, light blue in preservative; thighs and precloacal region without brown spotting; ventral surface of tail lemon yellow in life, becoming white posteriorly, uniform light blue in preservative, either speckled with light brown spots (occasionally forming fragmented parallel longitudinal lines) or with speckling absent; palmar and plantar surfaces lemon yellow in life, light brown in preservative. (Slavenko et al. 2021).

Comparisons: Lobulia fortis differs from Lo. brongersmai in having unfused (vs. fused) frontoparietals. It differs from Lo. lobulus in lacking dorsolateral and lateral stripes. Lo. fortis is most similar to Lo. elegans in having unfused frontoparietals and lacking light blue or white dorsolateral and lateral stripes but differs from it in having higher counts of midbody scale rows (34–37 vs. 30–32) and paravertebral scales (55–65 vs. 52–54) and a lower number of nuchal pairs (one or two vs. three). (Slavenko et al. 2021).

Color in life: Dorsal surfaces coppery brown with two parallel mid-dorsal rows of large dark brown spots (Figs 6, 10). Sides dark brown to jet black, usually with thin coppery vertical stripes between dark blotches, which are more or less parallel to dorsal rows of spots. Chin white. Ventral surfaces of chest, abdomen, precloacal region, thighs and base of tail lemon yellow in adult males and white in females and juveniles. Palmar and planar surfaces lemon yellow. (Slavenko et al. 2021). 
CommentSimilar species: L. elegans. 
EtymologyFrom the single-ending Latin adjective, fortis, strong, in reference to Mt Strong, where the type series was collected.
