| Diagnosis | Diagnosis. Hemiphyllodactylus hongkongensis sp. nov. can be separated from all other species of Hemiphyllodactylus by having the unique combination of 5–6 chin scales; a manual lamellar formula of 3–3(4)–4– 4; a pedal lamellar formula of 3(4)–4(5)–4(5)–4; 24–25 continuous femoral and precloacal pores; 12–15 dorsal scales contained in diameter of eye; and 9–10 ventral scales contained in diameter of eye. Comparisons. We compared Hemiphyllodactylus hongkongensis with other members of the genus Hemiphyllodactylus from China and Indochina based on data obtained from the literature. We show the diagnostic characters separating this species from other nominal taxa of Hemiphyllodactylus in Table 4. Hemiphyllodactylus hongkongensis sp. nov. has 5–6 chin scales, which separates it from H. changningensis Guo, Zhou, Yan & Li (7–8), H. chiangmaiensis Grismer, Wood & Cota (8‒12), H. dushanensis (8–10), H. huishuiensis (8–10), H. jinpingensis Zhou & Liu (7–9), H. longlingensis Zhou & Liu (7–9), H. typus Bleeker (9– 14), H. yunnanensis (7–8), and H. zugi (9–12). Hemiphyllodactylus hongkongensis sp. nov. has a manual lamellar formula of 3–4–4–4 or 3–3–4–4 which distinguish it from H. changningensis (3–3(4) –3(4) –3), H. chiangmaiensis (3–3–3–3, 3–4–3–3), and H. dushanensis (3–4–5–4, 4–5–5–4). It differs from H. banaensis Ngo, Grismer, Thai & Wood (4–5–5–5), H. dushanensis (4–5–5–5, 5–6–6–5), and H. zugi (4–5–5–5) by having a pedal lamellar formula of 3–4–4–4, 4–4–4–4 or 4–5–5–4. It differs from H. banaensis (18–21), H. changningensis (19–22), H. kiziriani Nguyen, Botov, Le, Nophaseud, Zug, Bonkowski & Ziegler (10–13), H. huishuiensis (0–20), H. yunnanensis (0–20), and H. zugi (18–21) by having 24–25 continuous femoral and precloacal pores in adult males. Hemiphyllodactylus hongkongensis sp. nov. has 12–15 dorsal scales contained in the diameter of the eye, which separates it from H. banaensis (17–20), and H. zugi (20–22). It differs from H. changningensis (6–8), H. jinpingensis (5–7), H. kiziriani (11–15), H. longlingensis (6–7), H. yunnanensis (5–7) and H. zugi (15–16) by having 9–10 ventral scales contained in the diameter of the eye. |
