Baptista hoedli Zettel, 2004: 441 .

Material examined. CHINA, Yunnan Prov.: 10 macropterous males, 5 macropterous females, 1 apterous male, Lincang city, Cangyuan county, Banhong village , Nangunhe Natural Reserve , Xiyan River (23°17'N, 99°04'E), alt. 613m, 5.V.2011, coll. Zhen Ye.

Diagnosis. This species differs from B. collaris in its larger size, darker colouration on the head and the sides of the thorax, more deeply emarginate posterior margin of abdominal segment VIII in the male ( Fig 22 ), and, most distinctly, in the wide distal dilatation of the male paramere (Figs 30, 31).

Redescription. Macropterous male ( Fig 3 ). Colour: ground colour dark brown, head blackish, clypeus and pseudocellar spots slightly darker, rostrum yellowish with black apex, buccula yellow; antennal segments I–II yellowish, III–IV brown; pronotum dark brown, area behind head along anterior margin with narrow pruinose mark, covered by silvery patches (except medially); legs mainly yellowish, with apices of femur, tibia, and tarsi weakly infuscated; abdomen dorsally and laterally brown, ventrally varying from orange to brown, laterosternites orange; posterior mediotergites more or less dull orange; forewing dark brown with six white spots; segment VIII, pygophore and proctiger yellowish, each strongly infuscated apically. Structural characteristics: body length: 2.82–2.91; medium-sized for genus, elongate, bearing short, grayish or golden, appressed pubescence. Head about 1.58 times as wide as long, posteriorly inserted into medially concave anterior margin of pronotum, head along inner eye margin with prominent silvery pubescence, labrum angulate, bucculae clearly visible; antennae long and slender, about 0.64 times as long as body, lengths of antennal segments I–IV: 0.38, 0.27, 0.53, 0.67; pronotum width: 1.02–1.04, length: 0.88–0.92, about 1.16 times as wide as long, pentagonal in outline, with anterior margin deeply emarginated; pronotum with paired of patches of dense silvery pilosity behind anterior margin; pronotal collar angularly widened behind eyes, ventrally narrowed. Legs bearing mainly decumbent or suberect setae, femur ventrally with relatively long, erect setae, fore femur simple, slightly incrassate, not curved, without special modifications except for patch of relatively long, erect setae ventrally ( Fig 15 ); fore tibia straight ( Fig 15 ), with conspicuous row of short, black, curved and pointed spines ventrally (Fig 18), grasping comb short, about 0.19 times tibia length; lengths of leg segments (femur, tibia and tarsi): fore leg: 0.79, 0.70, and 0.26, middle leg: 0.86, 0.85, and 0.38 (0.15+0.23), hind leg: 1.04, 1.1, and 0.44 (0.2+0.24); forewing with relatively long, suberect setae along basal longitudinal veins, with some golden, decumbent setae on transverse veins delimiting basal cells; length of forewings slightly surpassing end of abdomen; abdomen pleurally and ventrally without special modifications, except sternite VII with posterior margin bearing a V–shaped incision medially ( Fig 11 ), segment VIII about 1.9 times as long as wide, ventrally without modifications, conspicuously emarginated dorsocaudally ( Fig 22 ). Genital segments: pygophore sub–rectangular; proctiger small, narrow, and elongate, with apex acute (Fig 29); paramere long, symmetrical, strongly widened distally, apex curved, acute (Figs 30, 31).

Macropterous female ( Fig 4 ). Similar to male in general structure and coloration but slightly larger; body length: 2.85–3.05, structure of head including antenna as in male, head about 1.56 times as wide as long, antennae about 0.55 times as long as body, lengths of antennal segments I–IV: 0.35, 0.23, 0.49, 0.63; pronotum as in male, width: 1.05–1.16, length: 0.98–1.02, about 1.16 times as wide as long; fore tibia without grasping comb, lengths of leg segments (femur, tibia and tarsi): fore leg: 0.77, 0.63 and 0.31, middle leg: 0.88, 0.80, and 0.41 (0.17+0.26), hind leg: 1.00, 1.08, and 0.50 (0.21+0.29); abdomen pleurally and ventrally without special modifications; connexiva approximately rectangular dorsocaudally; gonocoxa and proctiger relatively small, proctiger with apex acute.

Apterous male ( Fig 5 ). Body length 2.80; head about 1.58 times as wide as long, antennae about 0.64 times as long as body, lengths of antennal segments I–IV: 0.36, 0.25, 0.50, 0.68; pronotum hind margin broadly rounded, width: 0.81, length: 0.6, about 1.35 times as wide as long; lengths of leg segments (femur, tibia and tarsi): fore leg: 0.75, 0.63, and 0.29, middle leg: 0.86, 0.80, and 0.38 (0.16+0.22), hind leg: 1.00, 1.07, and 0.48 (0.2+0.28); grasping comb about 0.19 times tibia length; lateral parts of mediotergites V–VI with silvery pubescence, mediotergites VI–VII shiny orange. Other characters as in macropterous male.
