One male mature larva (AMC /ZN/279) and two female larvae (AMC /ZN/280), India, Tamil Nadu, Theni district, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=77.56722&amp;materialsCitation.latitude=10.051945" title="Search Plazi for locations around (long 77.56722/lat 10.051945)">Anai Pillayar Kovil Dam</a>, 10°03′07″N, 77°34′02″E; 336 m . a.s.l., 23-XII-2020, leg. P. Srinivasan &amp; R. Isack .</p><p>Distribution. The species is reported from India (new record), Java (Malzacher, 2015), Sumatra (Malzacher, 2015), Thailand (Malzacher, 2015; Malzacher &amp; Sangpradub, 2021), Myanmar (Malzacher, 2023) and Philippines (Malzacher, 2023) (Fig. 28).</p><p>Diagnostic characters. Caenis ulmeriana can be distinguished from all other Caenis species by the following combination of characters: Imago (Imaginal characters extracted from the male last instar larva): base of antennal flagellum not dilated (Fig. 2); prosternal triangle forming cone-shaped structure (Fig. 3); foretarsus segments 2–4 each with a lateral and median projections (Fig. 4); penis broad and rounded, ventral fold forming a semicircular or semielliptical process (Fig. 5); forcipes moderate, straight, sides apically converging with a rigid elongated spine or a moderate spine equipped with an apical tuft of long spines (Fig. 6).</p><p>Larva. Genae slightly bulged; pronotum and mesonotum denticulate without any nose-shaped projection (Fig. 13); maxillary palp segment III clearly longer than segment II (Fig. 10); ratio of labial palp segments 2 and 3 greater than 2 (Fig. 12); forefemur with a transverse row of 8–10 conspicuous spatulate setae (Fig. 15); foreclaw slender with 2–3 small basal denticles (Fig. 17); midclaw bowed with 3–5 small basal denticles (Fig. 19); hindclaw strongly bent with 2–3 basal denticles, and a dense row of microdenticles (Fig. 22); dorsal surface of tergalius II with numerous scales and 2–5 spatulate setae on the apical 2/3 rd of Y-shaped ridge (Fig. 23); hind margin of tergum VII and VIII with long, simple setae, and hind margin of tergum IX and X with small denticles (Fig. 26).</p><p>Ecology. The larvae of Caenis ulmeriana were collected in Anaipillayar dam of the southern Western Ghats (3–5 m wide, 0.5–1 cm depth). The water temperature ranges between 24–26°C; pH 7–7.2. Substratum is mainly made of rock, cobbles, gravel and leaf litter (Fig. 27).</p></div>	https://treatment.plazi.org/id/703487DEFF89FFA5FFE7F994FBD419E5	Public Domain	No known copyright restrictions apply.
