| Diagnosis | Diagnosis: Alopoglossus gansorum sp. nov. is distinguished from all other species of Alopoglossus by the combination of the following characters: (1) non-granular, keeled, imbricate scales on medial and posterior sides of neck, varying from phylloid to mucronate with almost rounded posterior margins, in 11–14 transverse rows; (2) four pairs of chin shield scales; (3) laterally to the fourth pair of chin shields, two large well-developed scales separating the third pair of chin shields from gular scales; (4) smooth scales along midventral gular region, with almost rounded posterior margins; (5) smooth scales on anterior temporal region; (6) feebly pointed distally scales on posterior temporal region; (7) smooth first supratemporal scale; (8) feebly keeled distally second supratemporal scale (smooth aspect), with an almost flat aspect, just slightly folding laterally toward the temporal region; (9) supratemporal scales separated from each other by a temporal scale, or touching each other with acute contact margins; (10) 20– 23 total number of femoral pores in males. Alopoglossus gansorum sp. nov. is also distinguished from other species of Alopoglossus by the combination of the following hemipenial characters: (11) progressive widening of the sulcus spermaticus; (12) sulcus spermaticus running in the frontal face of the base of the lobes; (13) sulcate face with a fine area parallel to the sulcus spermaticus without ornaments; (14) hemipenial body and base ornamented by 24 transversal flounces covering almost the complete organ; (15) lobes with pointed distal ends; and (16) absence of hemipenial body distal expansion. |
| Comment | |
| Etymology | The specific epithet in genitive plural refers to Carl Gans and the Gans family. Members of the Carl Gans family run the Gans Collections and Charitable Fund, a private foundation established by Carls Gans to offer grants to students or researchers working in collection-based research. Their efforts in continuing and perpetuating Carl Gans’ legacy in taxonomy have allowed the discovering of considerable species diversity in the main ecoregions around the globe, from the Sahara Desert to the Amazonia. The uncovered species diversity and new descriptions supported by the Gans Fund become crucial tools in conservation policies. The foundation also helps to keep alive and active taxonomy initiatives, a field in general biology often neglected by governments and policy decisions. This study and many others were only possible thank to the Gans Collections and Charitable Fund. |
