description: Trachypeplus wapi sp. n.
(figs. 14, 15)
Material examined: 1 Ψ, Laos, Wapikhamthong prov., Khong Sedone, Wapi, 30.VIII.1967, native coll., Bishop.
Description: body shiny, yellowish to brownish, a transverse band across hemelytra at posterior third of discoidal area level, spot at apex of costal area, top of median carina darker; legs and body beneath brown; hind tarsi darker. Body length, 3.17; width, 1.20.
Head pilose on top, armed with five long, slender, erect spines; antennae slender, first two segments stouter, antennal segment measurements: I, 0.13; II, 0.10; III, 0.73; IV missing; bucculae broad, triseriate, closed in front; rostral sulcus straight, narrow, open behind; laminae broad, foliate, its areolae rather large; rostrum reaching middle of metasternum.
Pronotum long, gibbose, tricarinate, carinae parallel; median carina raised, uniseriate posteriorly, biseriate anteriorly, its areolae small; lateral carinae raised, uniseriate, less high than median carina; collar broad, three to four areolae wide, raised on top to form a hood, narrow, arced, five areolae long, produced forwards, less high than median carina but higher than top of pronotum; paranota four areolae wide, reflexed, partly resting on pronotum, not in contact with pronotum at opposite humeri, but raised and divided into two convex parts, separated by a transversal crest, the three outer rows also separated from inner row by a longitudinal crest. Carinae, hood, and paranota crests and margins armed with a row of spines regularly spaced.
Hemelytra long, as wide as pronotum, boundary veins raised, areolae almost of same size in all areas; costal area biseriate; subcostal area as wide as costal area, biseriate; discoidal area longer than half hemelytra, eight areolae wide at widest part; sutural area eight areolae wide at widest part; boundary veins RM and Cu between subcostal and discoidal areas; discoidal and sutural areas regularly armed with spines regularly spaced.
Etymology: The name refers to the type locality.
Comments: Although this description is based on a single specimen, it does not correspond to any other Trachypeplus species. It is close to T. malloti Drake & Poor but differs by the spines present on the body while short, the longer cephalic spines, the median carina biseriate on its anterior part, and the presence of a longitudinal ridge on the paranota. It is also close to Pseudurentius borneensis (Péricart) by the form of paranota and the median carina; but it differs by the discoidal area, sutural area, and the paranota being narrower, and the shorter spines on the hemelytra and pronotum.
Comments: Trachypeplus is close to Pseudurentius Péricart. Pseudurentius was raised on the basis of the large pronotal and hemelytral spines (Péricart 1992). However, the variation of the size of the spines within Pseudurentius and Trachypeplus makes the difference between these two genera difficult and blurred.
