Genus Indopalpares Insom & Carfi, 1988

Indopalpares Insom & Carfi, 1988: 77 .

Type species: Palpares pardus Rambur, 1842: 375 . Original designation and monotypy.

Diagnosis. Indopalpares can be characterized by the short labial palpus with oval palpimacula (Fig. 3D), presence of long black setae on antennal scape (Fig. 3F), triangular male sternite 9 with acutely tapering apex (Fig. 4D), cylindrical and arcuated male ectoproct (Fig. 4C) with a single prominent seta on short tubercle at base (Fig. 4D), male gonocoxites 9 with a median sensory bulla (Fig. 4E–F), and feebly developed gonarcal bulla (Fig. 4F).

Distribution. East Indies, India, Myanmar, Pakistan, Sri Lanka (Iqbal & Yousuf 1990, 1997; New 2003; Stange 2004; Ghosh 2000; Hassan et al. 2019; Tauber et al. 2019; Oswald 2021).

Remarks. Indopalpares is an endemic monotypic genus only known from Pakistan and India. Stange (2004) noted that the only autapomorphy of Indopalpares is the basally bent gonarcus (i.e., male gonocoxites 11). Morphologically, Indopalpares shares many similar characters with Palparellus Navás, 1912 and Pseudopalpares Insom & Carfi, 1988; including small labial palp with oval palpimacula, cylindrical and slightly arched ectoprocts, and presence of one prominent seta on short tubercle in male ectoprocts. However, Indopalpares and Pseudopalpares are still considered monotypic genera with species that have a limited geographic range, Indopalpares is limited to the Oriental region (Pakistan and India) (Fig. 5), while Pseudopalpares is limited to the Southern and Eastern African domains (Stange 2004). In addition to the above similarities, these two genera share parameres (i.e., male gonocoxites 9) with a median sensory bulla, which is absent in Palparellus .
