Male (n = 5): total length (TL): 3.2 (3.1–3.3); head length in midline (HL): 0.72 (0.7–0.75); preantennal width (PAW): 0.34 (0.33–0.35); temporal width (TW): 0.46 (0.45–0.47 mm); pronotal length (PL): 0.19 (0.18–0.2); pronotal width (PW): 0.35 (0.3–0.4); pteronotal length (PtL): 0.485 (0.48–0.49); pteronotal width (PtW): 0.48 (0.475 –0.485); abdominal length in mid line of dorsal side (AL): 1.80 (1.75– 1.85); genitalia length (GL): 0.65 (0.63–0.67); genitalia width at parameres (GW): 0.105 (0.09–0.12); length of parameres (PML): 0.17 (0.15–0.19). Female (n = 5): TL: 3.65 (3.6–3.7); HL: 0.765 (0.76–0.77); PAW: 0.36 (0.34–0.38); TW: 0.47 (0.45–0.49); PL: 0.22 (0.21–0.23); PW: 0.37 (0.36–0.38); PtL: 0.52 (0.51–0.53); PtW: 0.58 (0.56–0.6); AL: 2.39 (2.37–2.41).</p> <p>Material examined. Four males, 10 females from A. indicus; 3 males, 8 females from A. albifrons; 9 males, 12 females from A. anser, Aug. 2005 to Aug. 2007, Pakistan: Karachi, Thatta, leg. S. A. Rizvi and S. Naz.</p> <p>1 According to Clay &amp; Hopkins (1951). 2 According to Zlotorzycka (1980).</p> <p>Remarks. Anaticola crassicornis closely resembles A. anseris in having an elongate body with dark brown lateral margins, and the two species have similar head chaetotaxy, a temporal margin, pterothoracic characters, and abdominal chaetotaxy. Anaticola crassicornis can easily be differentiated from A. anseris, however, by clypeal features, body size, pterothoracic lateral margins, and male genitalia (Table 2).</p> </div>	http://treatment.plazi.org/id/787F87CA5153FFD6FF7BFAE5FAA83A35	Public Domain	No known copyright restrictions apply.
