Tedrow R, Nathan K, Richard N, Svenson GJ - Zookeys (2014)

Bottom Line: Therefore, a new species is described, Dystacta tigrifrutex sp. n., along with the first instar nymphs and ootheca.In addition, the previously monotypic genus Dystacta Saussure, 1871 is re-described to provide a broader definition of the genus group.Habitus images, measurement data, a key to species, natural history information, and locality data are provided.

ABSTRACT
A recent targeted entomological survey in the Republic of Rwanda has produced two conspecific male and female specimens of an undescribed species of praying mantis (Mantodea). The specimens were collected in Nyungwe National Park in May of 2013. The species is closest morphologically to Dystacta alticeps (Schaum, 1853). Therefore, a new species is described, Dystacta tigrifrutex sp. n., along with the first instar nymphs and ootheca. In addition, the previously monotypic genus Dystacta Saussure, 1871 is re-described to provide a broader definition of the genus group. Habitus images, measurement data, a key to species, natural history information, and locality data are provided.

Figure 2: Dystacta male prosternum (scale bar = 1 mm), posterior margin on the left: ADystacta alticeps Schaum, 1853 BDystacta tigrifrutex sp. n.

Mentions: Thorax: Longer than wide, with an expanded supra-coxal bulge; dorsal surface smooth. Medial region of prozone peaked, sloping to the anterior margins; medium length with margins gradually tapering anteriorly to a rounded anterior margin; the margins smooth, but with setae present. Metazone with two tubercles positioned on each side of the medial line just anterior to the posterior margin, a raised carina oriented anterolaterally, extending to the lateral margins of the metazone. Metazone with concave lateral margins tapering posteriorly until two thirds from the supra-coxal bulge, then widening to the posterior margin; margins smooth, but with setae present; the dorsal surface of the metazone not depressed. Ochre with faint black markings. Prosternum with or without a complex black and whitish pattern (Fig. 2); if present, a transverse black band anteriorly and a curved black band posteriorly, the posterior half of the medial region whitish colored, the anterior half with a trapezoidal shape of brown surrounded by a thin black band, the trapezoid reaching the lateral margins. The wings elongate, extending well beyond the terminus of the abdomen. Forewings opaque; setae along the anterior margin, the costal region densely ciliated, the discoidal region ciliated or not; the discoidal region smoky brown or grey with dark splotches; the veins more pigmented than surrounding cell colors; the medial and cubital veins are divergent and widely spread. Hindwings with setae along anterior margin; mostly matching coloration of forewing; the wings extending beyond the abdomen.
