Apterodina ruminyahui Flowers , new species

( Fig. 6 , 11 , 24, 32 , 33 )

Holotype: Female. Body oval; length 4.1 mm. Head, pronotum, elytra, and underside black; antenna with scape and pedicle reddish brown, segments 3–11 piceous. Underside piceous with femora, tibiae, and tarsae reddish brown. Mouthparts reddish brown, mandibles piceous. Prothorax wider than long, L/W = 0.6, pronotum with anterior angles rounded, posterior angles obtuse, lateral margins narrow, weakly undulate, greatest width of pronotum anterior to middle; disc regularly, densely punctate, with punctures separated by distances less than their diameters. Prosternum with a thick perpendicular anterior margin; intercoxal process strongly raised anteriorly, posterior margin of intercoxal process truncate, width of intercoxal process 0.83 x diameter of procoxa. Lateral arms of prosternum with a raised bead along the anterior margin. Metasternum very narrow between meso­ and metacoxae, with scattered yellow setae. Elytra with punctures arranged in irregular striae, punctures in striae separated by distances less than their diameters; humeri not prominent, width across humeri 1.16 x width across pronotum. Hind wing reduced to tiny lobe ( Fig. 11 ). Scutellum V­shaped. Abdomen with sternum VII with lateral margins smooth, pygidium with long fine setae in apical half. Abdominal segments VIII–XI forming long ovipositor ( Fig. 24 ). Baculum distinct, apical, subequal to gonocoxae. Gonocoxae moderately elongate, with long setae in apical half. Spermatheca ( Fig. 32 ) with receptacle bulbous, pump elongate, coiled; spermathecal duct fine, membranous.

Male. Unknown.
