Present investigation was carried out to understand morphological differences in two closely related congeners, the greater mouse-tailed bat&nbsp;<em>Rhinopomamicrophyllum&nbsp;</em>(Br&uuml;nnich, 1782) and the lesser mouse tailed bat&nbsp;<em>Rhinopomahardwickii&nbsp;</em>(Gray, 1831). Variations in external body, cranial and bacularfeatures were recorded and compared. During present survey, specimens of&nbsp;<em>R. microphyllum</em>(n=58) and&nbsp;<em>R. hardwickii</em>&nbsp;(n=25) were roosting at two different caves (N34&ordm; 26.783&prime; E71&ordm; 49.070&prime; and N34&ordm; 26.818&prime; E71&ordm; 48.973&prime;) in Malakand division, Khyber Pakhtunkhwa (KPK). Out of these, 3 specimens of&nbsp;<em>R. microphyllum</em>and 5 specimens of&nbsp;<em>R. hardwickii</em>&nbsp;were captured.&nbsp;<em>R. hardwickii</em>from KPK was recorded only from Amb prior to the present investigation indicating range extension of the species.</p> Cranial measurements; baculum size; R. microphyllum; R. hardwickii; Malakand Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2017-JAPS-11
