Sculpture of occiput and posterior vertex: coarsely punctate. Sculpture of frons below ocellus in female: coarsely punctate. Shape of dorsal margin of frontal scrobe: ecarinate, rounded onto dorsal portion of frons. Sculpture of frontal depression in female: punctate, with broad smooth spaces between punctures. Sculpture of gena: coarsely punctate. Setation of gena: with short, uniform setae, with few short bristles interspersed. Shape of mandibles: normal length, crossed transversely below head when closed, tips overlapping.

Sculpture of dorsal pronotum: areolate rugose, with distinct longitudinal tendency. Notaulus: absent or obscured by coarse surface sculpture. Sculpture of mesoscutum in female: sparsely punctate, with broad smooth areas between punctures. Sculpture of mesoscutum in male: sparsely punctate, largely smooth. Parapsidal line: absent. Mesoscutellum shape: nearly parallel-sided, apex weakly excavate, with weak median longitudinal impression. Sculpture of female mesoscutellum: areolate rugose. Scutellar points of female: broad, short, acute. Sculpture of male mesoscutellum: areolate rugose. Scutellar points of male: apex of mesoscutellum rounded, points entirely absent. Posterior surface of propodeum: irregularly areolate, without distinct paramedian keel. Length of outer propodeal projection in female: moderately elongate, extending to midpoint of length of T 1, distinctly longer than inner propodeal projection. Sculpture of propodeum between inner and outer propodeal projections: coarsely punctate. Netrion shape: moderately wide, weakly fusiform, anterior margin foveate. Netrion setation: densely setose. Sculpture of lateral pronotum posterior to epomial carina: coarsely punctate. Setation of posterior half of lateral pronotum: with numerous scattered setae, densest near spiracle. Sculpture of mesopleural scrobe: smooth. Sculpture of lower mesepisternum: with distinctly separated, coarse punctures. Sculpture of metapleuron: coarsely areolate to rugose throughout. Fore wing venation: well-developed, with R, r-rs clearly visible. Submarginal vein bristles: with dark bristles extending length of submarginal vein. Long dark bristles on legs: absent.

T 1 depression: moderately to densely setose. Sublateral lamella on T 1: distinctly raised more or less perpendicular to T 1. Sculpture of T 2 –T 4: longitudinally striate, with fine cross striae, punctures, smooth or finely punctulate transverse band apically. Setation of laterotergites: setose. Sculpture of S 2, S 3 of female: longitudinally rugulose laterally, nearly smooth medially, with scattered small punctures. Sculpture of S 2, S 3 of male: strongly longitudinally rugose. Distribution of felt fields: present on S 2 –S 3.

Diagnosis. This species is most similar to H. lugens  , from which it may be distinguished by the very short mesoscutellar spines (Fig. 66) and the lack of longitudinal rugulae on the mesoscutum (Fig. 67).

Etymology. The epithet paralugens  refers to the similarity of this species with Heptascelio lugens  , the type species of the genus.

Material Examined. Holotype female: PHILIPPINES: Negros Oriental, 7 km W Valencia, Cuernos de Negros, 700 m, ROMAbout ROM 873061, 1 E forest edge, 29.VI– 8.VII. 1987, Malaise trap w/ pans, D.C. Darling, OSUCAbout OSUC 209012 (deposited in ROMEAbout ROME) 54. Paratypes: PHILIPPINES, 5 males, 2 females, OSUCAbout OSUC 59556, ROMEnt 112071 – 112075 ( ROMEAbout ROME), OSUCAbout OSUC 209013 ( CNCIAbout CNCI).

Comments. The diagnostic characters for this species are, overall, rather weak. Further collections in the Philippines may help to determine if H. paralugens  is consistently separable from H. lugens  , or if the characters that distinguish them are variable and independently distributed.
