Apetasimus conditus Ewing sp. nov.
Diagnosis
Distinguishable from other involucer -group members by the combination of prosternal process strongly recurved dorsad behind coxae, eyes large ( Fig. 2 View FIGURE 2 L) and reduced tarsal lobes ( Fig.4 View FIGURE 4 M), from brachypterous Eupetinus by reduced tarsal lobes ( Fig. 4 View FIGURE 4 M), and brachypterous Gonioryctus by the less acute temple.
Description
Size: Length 4.0mm, Width 2.1mm.
Color: Dorsum of head, pronotal disc, small area adjacent to scutellum on elytra, and abdominal tergites orange-red, marginal beads of pronotum and elytra, anterior and posterior margins of pronotum, margin of paratergites, tergites at spiracles, median basal portion of tergites 5 and 6, scutellum and elytra brick red, explanate margins of pronotum and elytra, and paratergites pale yellow.
Head: Transverse, 0.70mm L, 1.0mm W, L/W ratio 0.70. Punctation on vertex coarse, dense, shallow and granular inside, punctures usually contiguous, finer and shallower on frons, punctation obsolete near labrum, surface roughened, intervals narrow, uneven and glabrous on frons, granular on clypeus. Eyes medium, length 0.21mm, facets coarse, 12, medial margins convergent anterad. Temple narrow, subacute, postgena broadly convex ( Fig. 2 View FIGURE 2 L). Antennomeres 1–4 elongate, 5 quadrate, 6–8 transverse.
Prothorax: Pronotum transverse, 1.15mm L, 1.79mm W, L/W ratio 0.64 ( Fig. 4 View FIGURE 4 L). Disc convex, lateral margin upturned posterad, pair of shallow impressions on either side of midline before margin. Lateral edge weakly explanate behind anterior angle to middle, increasingly explanate from middle to widely explanate posterior angle. Lateral margin evenly rounded to subacute posterior angles. Widest behind midpoint, anterior/posterior width ratio 0.65. Anteriorly emarginate, posterior margin shallowly bisinuate. Punctation less coarse and dense than on head, intervals glabrous with fine linear microsculpture. Bead extending from anterior angle to posterior angle, posterior marginal bead widest at midline, thin and indefinite near hind angle. Prosternal process short, strongly recurved dorsad behind coxae, meeting mesosternum at ~60° angle, apex with long fimbria ( Fig. 4 View FIGURE 4 G).
Elytra: 1.55mm L, 1.04mm W, L/W ratio 1.49 ( Fig. 4 View FIGURE 4 K). Surface uneven. Striae shallow, wider than interstices. Striae irregular, interstices glabrous with fine, irregularly arranged punctures. Lateral margin rounded anterad, sinuate for posterior 1/5. Posterior margin shallowly sinuate.
Legs: Protarsi with small lobes, tarsomere 1 with largest, smaller on 2, obsolete on 3 ( Fig. 4 View FIGURE 4 F). Meso- and metatarsal lobes obsolete on 1–3, parallel in dorsal view, ventral setae sparse ( Fig. 4 View FIGURE 4 M).
Abdomen: Female; surface of tergite 5, 6, and pygidium with granular microsculpture, punctation on pygidium coarser. Posterior margin of pygidium broad, truncate, rounded laterally, with shallow medial depression at posterior margin appearing emarginate when viewed from certain angles, fimbria short laterally, longer across midline. Terminal sternite broadly rounded.

Etymology: (L.) conditus ; hidden, secret.
Distribution: Known from type locality.
Habits: Fogged with pyrethrin from moss covered Cibotium tree fern trunk.
