( Fig. 7A , 13B )

Rhagovelia malkini Polhemus, 1997: 235–237

Diagnosis. Body length: apterous male (~5.4), apterous female (~6.3), macropterous male (~5.8), macropterous female (~6.3). General color orange-brown; anterior band of pronotum slightly lighter-colored than remainder of dorsum. Pronotum completely covering mesonotum. Lateral portions of mesosternum with 3–4 small black denticles. Proctiger not acuminate, not prolonged into spine-like process. Male fore tibia expanded distally; ventral surface with well-developed concavity. Posterolateral margins of male abdominal segment VII surrounding genital cavity with robust black denticles. Pronotum of macropterous female with elevated posterior projection. Basal portion of female middle femur not strongly flattened and concave; central section without transverse constriction. Anterolateral portions of apterous female abdominal mediotergites I–VII at most weakly pruinose, not contrasting with central portions. Central portion of apterous female abdominal mediotergite IV not covered by laterotergites, visible in dorsal view for entire length. Abdominal laterotergites of apterous female weakly convergent adjacent to mediotergites I–II, strongly convergent adjacent to III–IV, weakly convergent adjacent to remaining mediotergites, nearly meeting over posterior margin of tergum VIII. Abdominal mediotergite VII of apterous female lacking tuft of long, black setae on posterior margin. Abdominal tergum VIII of apterous female not completely covered by long, erect, black setae. Male paramere and proctiger as in Polhemus (1997: 235, figs. 264, 265).
