Diagnosis

This species is most similar to other Southeast Asian Voconia species with a finely granulose head and pronotum and yellow spots on the anteromedial, posteromedial, and distal apex of the abducted corium. Voconia hemera sp. nov. is larger than V. minima sp. nov. (9.2–9.3 mm). It is distinguished from V. ornata , V. nyx sp. nov., and V. bakeri sp. nov. by its uniformly yellow legs and antenna as well as its uniformly brown scutellum and dorsal laterotergites.

Etymology

Named after the Greek primordial goddess of the day, Hemera. Refers to the yellow legs and antennae of this species, which differs from a similar yet darker species, V. nyx sp. nov., named after the goddess of night. A proper noun in apposition.

Description

Male ( Figs 1–2 )

BODY LENGTH. 9.2–9.3 mm; macropterous.

COLORATION. Head: dark brown; postocular region with dark patches adjacent to medial ocellar margin, semicircular pale stripe encircling both ocelli; labium lighter than head, brownish yellow. Thorax: as head; scutellum uniformly dark brown. Hemelytron (abducted): clavus reddish-brown with distal yellow stripe; corium reddish-brown with anteromedial, posteromedial, and distal yellow spots; membrane dark with pale V-shaped marking along R and M veins; membranal veins R and M proximally pale. Legs: yellowish-brown. Abdomen: dark brown.

INTEGUMENT AND VESTITURE. Head and pronotum: finely granulose with dense, long macrosetae interspersed among dense pubescence; interocular region with two pairs of macrosetae paramedially; antennifer with short lateral setigerous tubercle; morphologically ventral surface of labium with dense, short macrosetae. Thorax: anterolateral angles of pronotal collar with macrosetae; scutellar lateral carinae with long setation. Hemelytron: corium with sparse long setation. Legs: posterior row of protuberances on mid and hind femora with three large and two small spines. Abdomen: ventral surface pubescent.

STRUCTURE. Head: elongate, about 1.3 times as long as wide; anteocular region about one third of head length, shorter than postocular region (measured to anterior margin of neck); postocular region in dorsal view about as long as eye, lateral margins gently rounded; pedicel about 1.2 times length of head width; maxillary plates ellipsoidal, adjacent to and as long as clypeus; apices of maxillary plates in dorsal view directed straight; clypeus in dorsal view wider than maxillary plates; clypeal apex round, not narrowed; interocular glabrous markings anterolaterally curved, joined at interocular sulcus paramedially; interocular sulcus in dorsal view bent anteromedially, subtriangular; eye width in dorsal view narrower than synthlipsis; eye reaching ventral head margin in lateral view; ventrolateral swelling of buccula without lateral protrusion that surpasses buccular margin, flat margin; labial segment I in lateral view straight, surpassing posteroventral eye margin; morphologically dorsal surface of labial segment II nearly straight, about 0.5 times length of segment I. Thorax: pronotal collar in dorsal view narrow medially, projected forward; anterior pronotal lobe about 0.8 times length of posterior pronotal lobe, lateral margins rounded; glabrous markings on pronotum thin, gently depressed; median apodeme depression of pronotum shallow, elongated transversely; scutellar spine long, raised; anteriad-directed process of prosternum smoothly rounded, without paramedial lobes; anterior margin of stridulitrum not elongated into protuberance; proepimeron with acute protuberance on posteroventral margin. Legs: fossula spongiosa present on fore and mid legs.

Female

Unknown.

Distribution

This species is only known from the type locality on the Philippine island of Luzon.

Remarks

The holotype locality of Los Baños is about 10 km from the holotype locality of V. nyx sp. nov. at Mt Maquiling.
