Caridina endehensis De Man, 1892

Caridina brevicarpalis var. endehensis De Man, 1892: 399 , Pl. 24 Fig. 30e [type locality: Nuawari, near Ende, Flores, Indonesia]; Bouvier, 1925: 34; Roux, 1928: 218; Blanco, 1935: 34, Pl. 2 Fig. 25; Chace, 1997: 8, Fig. 3 .

Caridina brevicarpalis – Holthuis, 1978: 38 (not Caridina brevicarpalis De Man, 1892 ).

Caridina endehensis – Wowor et al., 2004: 341, Fig. 5M ; Cai & Shokita, 2006a: 248.

Material examined. – 13 males, cl 3.0– 4.2 mm, 25 females, cl 2.7–6.2 mm, 2 ovigerous, females, cl 4.6–6.2 mm, ZRC 2007.0277 , river outside Inabacan Cave , Antequrra, coll. Y. Cai et al., 16 Dec.2000 ; 11 males, cl 3.2–4.6 mm, 13 females, cl 2.9–4.8 mm, 2 ovigerous females, cl 5.3–6.4 mm, ZRC 2007.0278 , river outside Inabacan Cave , Antequrra, coll. Y. Cai et al., 18 Dec.2000 .

Remarks. – Holthuis (1978) reported Caridina brevicarpalis from Sumba, Lesser Sunda Islands, Indonesia. According to his description, his specimens “can unhesitatingly be brought to ssp. endehensis ”. Caridina endehensis has previously been reported from the Philippines by Blanco (1935), Chace (1997) and Cai & Shokita (2006a). It is distributed from Philippines to Flores and Sumba in Indonesia. The prominently elongated rostrum easily separates C. endehensis from C. brevicarpalis and does not appear to be variable. We therefore follow Cai & Shokita (2006a) and regard the taxon as a full species.
