{"data":[{"source":"bio.acousti.ca","id":"50696.2","topic":"morphology","value":"In all of the four species studied in detail (A. montivaga, A. nou, A. hanangensis sp. nov., and A. nomima), the stridulatory file on the lower side of the left tegmen showed a similar structure (Fig. 2). In its proximal part it bears relatively large teeth, whereas they decrease slowly in size to the end of the file at the edge of the tegmen. In A. nomima both parts are connected by a more or less continuous transition in tooth size (Fig. 2D). In the other three species the teeth gradually become larger from the articulation towards the centre of the file. Distal of the middle the teeth become abruptly smaller, and then decrease slowly in size (Fig. 2A\u2013C).\n\nA file structure with two distinct parts in three of the four known species of Altihoratosphaga is quite different from that observed in other species of the genus Horatosphaga(H. heteromorpha, Horatosphaga legg(Kirby, 1909), and H. parensis; K.-G. Heller, C. Hemp, unpubl. data). Differences in the number of teeth and their size, as can be seen in Figure 2, may indicate species-specific parameters, but cannot be evaluated at present because of insufficient data.","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Morphology","info_url":"https:\/\/bio.acousti.ca\/node\/50696"}]}
