Epirodera fuliginosa Stål, 1870: 693.
Physoderes fuliginosa – Maldonado 1990: 380.
Diagnosis
This species is recognized among species of Physoderes by the elongate head, the scape reaching the apex of the clypeus, the hemispherical eye that is not distinctly protruding, the acute and diverging anterolateral projection of the anterior pronotal lobe, the anterior pronotal lobe being wider than the posterior lobe, the rounded parascutellar lobe, the slender and straw-colored scutellar process, the pygophore apical margin of the posterior opening having a short medial process and the phallosoma lacking flaplike prolongations. This species is most similar to P. minime sp. nov., but can be differentiated from it by the larger size, darker coloration, the hemelytron close to or attaining the tip of the abdomen, the presence of an apical median process on the posterior opening of the pygophore, and the lack of flap-like prolongations of the phallosoma.

Redescription
Male
BODY LENGTH. Medium, total length 10.47 mm, SD ± 0.54 (Appendix).
COLORATION (Figs 14, 17). Dark brown. Head dark brown. Scape and pedicel of antenna light brown and brown, basiflagellomere brown, distiflagellomere basally brown, apically straw-colored. First segment of labium brown, second segment basally and apically brown, medially straw-colored, third segment brown. Pronotum of thorax dark brown with light brown markings, scutellum basally dark brown with scutellar process straw-colored, pleuron straw-colored with brown and dark brown patterns, sternum dark brown with brown suffusion. Corium of hemelytron brown to dark brown, membrane dark brown. Femur and tibia of legs straw-colored with medial and apical brown annulations, tarsus and claw light brown. Abdomen dorsally yellowish-orange, ventrally straw-colored with sub-lateral dark brown patterns, anterior half of connexivum dark brown, posterior half straw-colored, exposed part of pygophore brown.
VESTITURE. Sparsely setose. Head with widespread curved setae, ventral surface of postocular lobe with sparse, setigerous tubercles, with pair of long, straight setae on postocular lobe posterior to ocelli. Anterior lobe of thorax with irregular row of tuberculated, short, curved setae on lateral margins and short, setigerous tubercles dispersed on dorsal surface, posterior lobe with short, curved setae on humeral angle and sparsely distributed along dorsal surface. Corium of hemelytron with short, curved setae. Legs with two rows of spines and setigerous tubercles, tibia with regular rows of tuberculated, stout, sharp setae. Connexival margin of abdomen with no prominent setae.
HEAD. Elongate conical; maxillary plate rounded apically; scape reaching apex of clypeus; eye hemispherical in dorsal view, less than 1/5 length of head.
THORAX. Antero-lateral paired projections acute, diverging; surface of anterior lobe with low ridges; median pronotal depression not contiguous with transverse sulcus; paramedian carina weakly defined; anterior pronotal lobe longer and wider than posterior lobe, higher than posterior lobe in lateral view; parascutellar lobe rounded; scutellum rounded triangular, scutellar process long, apex subacute.
HEMELYTRON. Reaching tip of abdomen.
LEGS. Same as genus description.
ABDOMEN. Connexival margin slightly undulating, posterior margin not elevated.
GENITALIA. Anterior margin of mediosternite 8 undulating, without medial apodeme; transverse bridge of pygophore narrow, margin of anterior opening angular, apodeme present, apical margin of posterior opening with small medial process; cup-like sclerite apically rounded with sclerotized paired lateroventral slight protuberance; arms of basal plate converging; ductifer membranous; endosomal struts conical, with subacute apex, divided into two arms basally; dorsal phallothecal sclerite not sclerotized.
Female
Similar to male, except with anterior pronotal lobe (2.39 mm average) distinctly narrower than posterior lobe (3.20 mm average) and with median pronotal depression contiguous with transverse sulcus.
Ecology
Nothing is known about the biology of this species.
Distribution
This species is widespread across the Philippines island archipelago and also recorded from Borneo, parts of the Indonesian archipelago, Papua New Guinea and the Solomon Islands.
Remarks
The holotype of P. fuliginosa is a female with a narrow anterior pronotal lobe and unknown locality, which makes it difficult to associate it with a male. Multiple male specimens found on Mindanao with corresponding females that match the holotype morphology confirm that the holotype is most likely from the Philippines region and the redescription here is based on the males from Mindanao. The description of P. fuliginosa is difficult, as specimens from the Philippines show variation in overall size and coloration, but do not differ morphologically. Dissections of male genitalia from different geographic localities also do not show any variation. Hence, P. fuliginosa is here considered to be highly variable in size and general coloration.
