|Diagnosis||Diagnosis (based on the type series, osteology based on micro-CT scan of ZSM 735/2003, female): Calumma tjiasmantoi sp. nov. is characterised by (1) a small size (male SVL 43.9 – 46.8 mm, female TL 84.1 – 94.8 mm);|
(2) a medium sized (1.1–2.1 mm) and distally rounded rostral appendage, (3) rostral scale not integrated into the rostral appendage, (4–8) rostral, lateral, temporal, cra- nial, and parietal crests present, (9) casque medium sized in males (1.3 mm), (10) a dorsal crest of 7 – 9 spines can be present in males (based also on photographs), absent in females, (11) 15–17 supralabial scales with a mostly straight upper margin, (12) general absence of axillary pits, (13) diameter of the largest scale in the temporal re- gion of the head 0.6 – 0.8 mm, (14) frontoparietal fenestra absent, (15) parietal and squamosal in contact, (16) pari- etal bone width at midpoint 16.1% of skull length (n = 1) with a characteristic broad tip to the postparietal process, (17) bright green or yellowish body colouration in males, females generally browner and less conspicuous, (18) rostral appendage colour generally inconspicuous, (19) cheek colouration greenish to turquoise, (20) five charac- teristic dorsoventral stripes of blue or brown colour, and (21) a diffuse brown stripe crossing the eye.
Calumma tjiasmantoi sp. nov. can easily be distin- guished from all species of the C. boettgeri complex (see above) by the absence of occipital lobes; from C. gal lus by different length, shape and colour of its rostral appendage (see above); from C. vatosoa by presence of a rostral appendage (vs absence); from C. vohibola by longer rostral appendage in females (RRS 2.4 – 4.6% vs 0.2 – 0.7%), parietal crest present (vs absent), smaller temporal scale (0.6 – 0.8 mm vs 1.0 mm); from C. nas utum as redefined herein by the higher number of su- pralabials (15 – 17 vs 12 – 15), a shorter rostral append- age (4.3% of SVL vs 4.5–5.3% of SVL), a shorter parietal (36.3% of skull length vs 41.0 – 44.3%), broad postparietal process (vs narrow); from C. radamanus by a relatively longer tail in females (RTaSV 92 – 95% vs 79 – 89%), rostral scale not integrated in rostral ap- pendage (vs generally integrated), parietal crest present (vs absent), more supralabials (15 – 17 vs 11 – 15) with a generally straight upper margin (vs serrated), parietal and squamosal in contact (vs widely separated); from C. emelinae sp. nov. by presence of parietal crest (vs usu- ally absent), absence of lateral white stripe, and broader postparietal process; for diagnosis against C. fallax, see below. For diagnosis against the other species described herein, see its description below.
|Etymology||The specific epithet is a patronym honouring Wewin Tjiasmanto in recognition of his support for taxonomic research and nature conservation projects in Madagascar through the BIOPAT initiative (http://biopat.de/en).|
