( Figs 13–14 View Figure , 31–32 View Figure )

Copelatus cryptarchoides Régimbart, 1899: 293  .

Copelatus nilgiricus J. Balfour-Browne, 1939: 74  ; synonymy by Vazirani (1970: 318).

Type locality. Copelatus cryptarchoides  : " Inde: Kanara " (Coastal Karnataka)  ; C. nilgiricus  : " India: Nilgiri Hills" (Tamil Nadu)  .

Type material. Copelatus cryptarchoides  : Lectotype ♂, designated by Vazirani (1970: 318), deposited in Muséum national d'Histoire naturelle, Paris, France (not studied); C. nilgiricus  : Holotype ♂, deposited in BMNH (not studied).

Kantner lgt. ( SMNSAbout SMNS)  ; 2 specimens, same data, but 12.–15.x.2005, F. & L. Kantner lgt. ( SMNSAbout SMNS)  ; 1♂, 1♀, Tamhini, 18°35.2′N, 73°18.2′E, 70 m, 27.viii.2013, S.D. Sheth lgt. (HVGC); 1♀, Tamhini , 18°26.7′N, 73°25.7′E, 625 m, 29.x.2014, S.D. Sheth lgt. ( HVGC)GoogleMaps  ; 1♀, Satara distr., Kaas area, 17°43.4′N, 73°49.5′E, 1237 m, 16.vii.2014, S.D. Sheth lgt. (HVGC).

Diagnosis. Small (TL: 3.7–4.2 mm), oblong oval species. Elytra yellowish-brown with blackish median square spot extending laterally to stria 3 and along suture to elytral base and apex, blackish longitudinal band between striae 4–5, indistinct infuscation subbasally between striae 5–6, and with narrow dark stripes along elytral striae ( Fig. 13 View Figure ). Elytral striae well impressed: stria 1 starting subbasally; striae 2, 3 and 5 shorter than striae 1 and 4—not reaching apex of elytra; stria 6 shortest, ending approximately in apical fifth of elytral length. Females dimorphic, with or without striolation ( Fig. 14 View Figure ). Median lobe sickle-shaped in lateral view, almost evenly curved except for basal fourth; apex narrowly pointed ( Fig. 31 View Figure ). Parameres moderately broad, 'C'-shaped; apex short and broad; apical lobes long, club-shaped ( Fig. 32 View Figure ).

Collecting circumstances. The species was collected in ephemeral water bodies ( Fig. 43 View Figure ).

Distribution. Widely distributed in south-western India. Ghosh & Nilsson (2012) listed the species from Karnataka, Kerala and Tamil Nadu. We add records from Maharashtra (Nashik, Pune, Ratnagiri and Satara districts) in the altitudinal range 70–1,237 m a.s.l. ( Fig. 45 View Figure ).
