CAU , Beijing // Holotype & / Vietnamaptera / secunda n. sp. / des. Bai, Heiss, Cai 2011 ( CAU ). Paratypes : 63 2ƤƤ collected with holotype ( CAU , 1Ƥ CEHI ); 1&1Ƥ China SE Yunnan / Daweishan Mts. 1700m / sifted / 15 V 2008 Vondrak ( CEHI ). Diagnosis. Differs from bogiessa by the clypeus shorter than antennal segment I, and from tertia n. sp. and quarta n. sp. by the characters given in the key. Description. Apterous male; colouration of body black, legs and antennae dark brown, thorax and abdomen with bulbous dorsal elevations; surface with deep punctures and rugosities, partly smooth. Head: Distinctly wider than long (23/19); clypeus shorter than antennal segment I, its apex subacute and projecting over lateral genae; antenniferous lobes short and pointed; antennae 1.22x as long as width of head (28/23), segment I strongly bent at base and thickest, II thinner and shortest, III thinnest and longest, IV as long as I and fusiform; length of antennal segments I/II/III/IV = 7/6/8/7; granular eyes oval inserted in head; postocular lobes roundly converging toward constricted collar; vertex with a median longitudinal ridge flanked by 2 (1+1) carinae and ovate depressions laterally. Rostrum arising from a slit-like atrium, as long as head, lateral margins of rostral groove carinate. Pronotum : Fused to mesonotum but separated by a deep transverse sulcus. More than 5x as wide as long (53/ 10), rectangular anterolateral angles separated by a deep incision from lateral projection of ring-like collar; lateral margins anteriorly carinate and concave, posterolateral lobes elevated, rounded, with granulate surface and have an upper and a lower edge separated by a longitudinal sulcus; disk with a rugose elevation at middle, this longitudinally sulcate, laterally and posteriorly smooth, posterior margin convex and raised. Mesonotum : Fused to metanotum but fusion line marked by a deep transverse groove. About 8x as wide as long (57/7) consisting of a rounded granulate elevation with a longitudinal sulcus at middle and 2 (1+1) lateral transverse sclerites with rugose surface, their lateral marginsraised and granulate and seemingly doubled by an upper and a lower lobe. Metanotum : Fused to mtg I+II, a thin transverse suture indicating fusion line; median rounded granular elevation as high but shorter than that of mesonotum; lateral sclerites strongly raised along posterior margins, these sloping to anterior groove, their surface smooth anteriorly, rugose posteriorly, lateral margins raised to ovate granulate lobes. Mtg I+II: Completely fused; mtg I with 2(1+1) large ovate rugose elevations depressed at middle; mtg II with a lower subrectangular smooth elevation at middle, surface lateral of these elevated structures smooth and sloping toward lateral margins. Abdomen : Tergal plate with a bituberculate granulate elevation, this highest on mtg III–IV, lateral parts with smooth surface; a pivot-like projection on mtg V directed posteriorly and reaching tergite VII; deltg I+II fused to a triangular sclerite anteriorly reaching to mesonotum; lateral margins of deltg II–VII angularly projecting, surface with deep punctures and carinae, pe-angles raised and granulate; tergite VII strongly raised medially for reception of pygophore, its surface with two larger tubercles; spiracles II–VII lateral placed on reflexed vltg II–VII and visible from above, VIII terminal on paratergites VIII. Venter : Surface of median parts of meso- and metasternum and sternites II–VII smooth and subglabrous, that of prosternum pleura and vltg II–VII granulate and rugose; sternite VII with 2(1+1) ovate finely granulate elevations ( Fig. 2 ). Legs : Slender and unarmed, femora and tibiae straight and cylindrical; claws with thin long pseudopulvilli. Genitalic structures : Pygophore declivous posteriorly, exposed surface irregularly rugose; parameres as Figs. 9–11 . Female : General structures as in male but of larger size; pivot-like projection of mtg V reduced and not reaching tergite VII; sternite VII without a peculiar structure; tergite VIII shorter than triangularly projecting tergites IX+X. Measurements. Holotype 3: length 5.0mm; width of abdomen across tergite III 3.05mm , variation of length in paratypes : 3 4.9–5.2mm , Ƥ 5.8–6.1mm . Etymology.
