Costa, Maria Kátia Matiotti Da, Pereira, Marcelo Ribeiro, Redü, Darlan Rutz, Martins, Luciano De Pinho & Zefa, Edison, 2014, A new Neotropical genus of Ommatolampidinae (Orthoptera: Acridoidea: Acrididae) from Brazilian Atlantic Forest, with chromosome complement, Zootaxa 3869 (4), pp. 493-500 : 495-498

Muriciacris triflavovittata n. sp.

Etymology. From Latin, tri (= three), flavus (= yellow) and vittata (alluding to the dorsal yellow bands on the abdomen).

Male. Body color dark green, with three transverse yellow bands along 5–7 abdominal tergites (Fig.1). Head mostly green over lateral ocelli, behind eyes. Clypeus, labrum and mandibles green, and maxillary and labial palpi yellow. Antennae dark green. Pronotum dark green. Meso-metapleuron green. Tegmen black, with yellow veins. Abdominal tergites green. Hind knees dorsally black. Coxae-trochanters, fore- middle, hind femora and hind tibiae of all legs green; first tarsi joint black. Lunules genicular reddish.

Measurements in mm, 7 Males / 13 Females, respectively: BL., 20 (17–20)/ 25 (21–27); PL., 3 (3–5)/ 5 (4–7); FL., 9 (10–11)/ 14 (12–16); TL., 2 (3–4)/ 5 (4–6).

Chromosomes (Fig. 14 and 15). 2n = 23, XO for males, and 2n = 24, XX for females; all chromosomes acrotelocentric, grouped in two large pairs (L1-L2), one of them bearing a pericentromeric elastic constriction; three sub-large pairs (SL3-SL5); three medium pairs (M6 - M8), and three small pairs (P9-P10); the X chromosome belongs to the SL group, with positive heteropyknosis during prophase I, and negative in metaphase I.

Type material. Holotype male: BRAZIL, Alagoas, municipality of Murici, Station Serra do Ouro, 19–23.i. 2013 (9° 14'7.50" S – 35° 50'10.40 "W), Zefa, E.; Pereira, M.; Redü, D. leg./ (MCT). Holotype condition: genitalia were extracted, and maintained in holotype's tube. Paratypes: same data of holotype, six adult males and thirteen adult females (MCT- PUCRS).

Habitat. The individuals were found in the understory, dwelling bushes shaded of Atlantic Forest, at an altitude of 500m, not yet recorded for Ommatolampae genus group from Atlantic Forest (Fig. 16).
