Katydids (Orthoptera: Tettigoniidae) of Gorongosa National Park and Central Mozambique Author Naskrecki, Piotr Author Guta, Ricardo text Zootaxa 2019 2019-10-04 4682 1 1 119 journal article 25307 10.11646/zootaxa.4682.1.1 3981e1e7-9d35-4f45-857c-da0bca835157 1175-5326 3472787 430B98EF-BFCB-4608-A562-DEFA9539C8B2 Plangia satiscaerulea Hemp, 2015 http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:470445 ( Figs. 44 A–E, 53J–L) Diagnostic remarks. Similar to P. graminea but the male cerci strongly bent inwards in the apical half and not narrowly tapered ( Fig. 44A ). Males frequently have a dark brown spot on the stridulatory area of the left tegmen ( Fig. 44C ). Both green and yellow forms of this species are known, the latter sometimes with brown, irregular spots on the dorsal (posterior) half of the tegmina ( Fig. 44B ). Bioacoustics. The call of P. satiscaerulea is very similar to that of P. graminea and consists of 2–3 syllabic echemes produced every 6–9s; mean syllable duration is 0.043 s (SD=0.0113, n=19); the peak frequency of the call is 9.3–12.3 kHz ( Figs. 53 J–L). The call is audible from a distance of a few meters. Distribution and natural history. P. satiscaerulea was recently described from Tanzania but this species appears to have a much wider distribution. In Mozambique it has so far been only recorded in Gorongosa , where adults can be found throughout the year. Females have a wide, relatively long ovipositor with a broadly rounded apex ( Fig. 44D ), adapted to laying eggs between the layers of the leaf epidermis ( Fig. 44E ). Measurements ( 3 males , 2 females ). body w/wings: male 43.3–43.8 (43.5.3), female 44.2–44.8 (44.5.4); body w/o wings: male 21.4–23.8 (22.21.4), female 27.2–29.7 (28.51.8); pronotum: male 6.5–6.6 (6.5.1), female 6.8–7 (6.9.1); tegmen: male 33.5–35.4 (34.51), female 37–38.4 (37.71); hind femur: male 14.9–17.1 (15.91.1), female 16.8–17.4 (17.1.4); ovipositor: 6.8–7.6 (7.2.6) mm.
