New signals are described for H. hoguei and a new call signal character from two new populations is provided for H. pacifica. Male calls ranged in complexity from ancestral-monophasic in H. hoguei to calls containing both monophasic and derived-grouped components in H. pacifica. Intersexual communication was less specialized in H. hoguei with 2-way (male call-female answer) duets, and more specialized in H. pacifica, having both 2-way and 3-way (male-call, female-answer, male-response) exchangesTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaPrirodoslovni muzej Slovenije
