The last decade has seen many new bat species described, including in western Palearctic . These newly described species, a large majority is the so-called cryptic species, that is to say, species that are morphologically very similar to one or more other species . These strong morphological similarities are why these species have escaped (figurative sense) Traditional taxonomists often using only morphological characters to identify and differentiate species .
miaka kumi iliyopita imeshuhudia wengi wa aina bat mpya ilivyoelezwa, ikiwa ni pamoja na katika magharibi Palearctic . Aina hizi wapya ilivyoelezwa, idadi kubwa ni kinachojulikana aina cryptic, kwamba ni kusema, aina ya kwamba ni morphologically sawa na moja au zaidi ya aina nyingine . Hizi nguvu kubadilika kwa maumbile yanayofanana ni kwa nini aina hizi kuwa alitoroka (maana ya mfano) Taxonomists Jadi mara nyingi kwa kutumia tu kubadilika kwa maumbile wahusika kutambua na kutofautisha aina .
