description: Cylindera (Conidera) mindoroana Zettel and Wiesner, new species
(Fig. 1–5, 8, 9, 14, 17, 20)
Etymology. Named after the terra typica, the island of Mindoro.
Type material. Holotype male, (coll. Wiesner, Wolfsburg, Germany, long term loan of Natural History Museum Stuttgart) and three paratype females (coll. Wiesner, Wolfsburg, Germany), Philippines, Mindoro, Mt. Halcon, IX.2010, leg. Noel Mohagan. One paratype female, (coll. Zettel, Vienna, Austria),
Oriental Mindoro, Roxas, San Vicente, 7.V., local collector. One paratype male, (coll. Wiesner, Wolfsburg, Germany), Philippines, Mindanao, Bukidnon Province, XI.–XII., leg. Noel Mohagan.
Diagnosis. Medium-sized species (body length 9.7–11.1 mm) of Conidera, with characteristic color pattern of the subgenus (Fig. 1, 2). Sides of clypeus glabrous. Labrum (Fig. 5) strongly protruded in middle, forming a lobe with small acute tip, with 16–18 setiferous pores. Mandible (Fig. 3, 4) with four teeth between basal dentition and apex; in male with large gap between tooth 1 and 2. Pronotum length slightly larger than width in males, subequal or smaller than width in females. Each elytron rounded posteriorly; sutural spine shifted anteriorly, in male slightly, in female strongly (Fig. 8, 9). Elytron of female with large, strongly glossy area expanded over entire humeri.
Description.
Measurements. Holotype: BL = 10.9, HW = 2.45, PW = 1.96, PL = 2.03, EL = 6.21. Paratype, male (n = 1): BL = 10.8, HW = 2.41, PW = 1.92, PL = 2.06, EL = 6.14. Paratypes, females (n = 4): BL = 9.7–11.1, HW = 2.24–2.52, PW = 2.00–2.38, PL = 1.87–2.02, EL = 5.59–6.27.
Color (Fig. 1, 2). Head dorsally black with greenish reflections on antennal plates, clypeus, and margins of labrum, occasionally also on foremargin of frons. Sides of head bluish green. Eyes pale. Mandibles testaceous at base, distally black. Labial and maxillary palpi testaceous, last labial palpomere and last 2–3 maxillary palpomeres with bluish infuscation. Antenna with antennomeres 1–4 metallic green with some bronze or blue reflections, antennomeres 5–11 black. Pronotum chiefly black with slight bronze tinge; sides with some slight greenish reflections. Ground color of elytra dull black, in male with slight olive greenish, in female with weak bronze tinge; punctures on green ground are blue. Humeral areas more vividly colored than rest of elytra, in male greenish, in female dark violet-blue; sides with narrow blue margins. White pattern as characteristic for the subgenus. Thoracic and abdominal sternal sclerites metallic green to bluish, much more vivid than dorsum. Legs: trochanters brownish bronze; coxae and femora metallic green to blue; tibiae and tarsi blue to bronze black.
Structures. Head narrow, fully glabrous, except one pair of setae at the dorsal eye margin. Eyes moderately globose. Frons and vertex coriaceous, with fine longitudinal striation, which is much stronger on suborbital declivity. Temples transversely striate; genae longitudinally striate. Clypeus finely shagreened, without setiferous punctures at sides. Labrum (Fig. 5) smooth, with numerous (16–18) setiferous pores (bearing long white setae if not broken off), twice as wide as long, with distinct medial lobe bearing a small apical tip. Mandibles very long and slender, with four teeth between basal dentition (covered by labrum) and apex; in male with large gap between teeth 1 and 2 (Fig. 3), in female without gap. Antenna very long and slender, in male reaching subapical spot of elytra, in female a little shorter than in male; scape and antennomeres 2–4 smooth, 5–11 dull.
Pronotum. Narrow, with maximum width near base; length slightly larger than width in males, subequal or smaller than width in females. Disk glabrous, coriaceous, with fine transverse striation that is more obvious at anterior collar. Sides densely punctured and pilose. Posterior transverse furrow deep, medially protruded forward. Mesepisternal coupling sulcus of female developed as a large and deep groove; surface smooth with few small punctures. Sides of prothorax including sides of pronotum, mesepisternum (except coupling sulcus of female), metepisternum, metasternum, abdominal sternites, and parts of forefemur covered with white adpressed to decumbent hairs. Legs with short white decumbent to subdecumbent stiff setae.
Elytra. Much wider than head (ca. 1.5 times), sides slightly and apex strongly convex; punctures fine and dense (Fig. 8, 9). Suture in male slightly and in female distinctly concave in posterior third. Sutural spine small and slightly preapical in male, larger and more distant from elytral apex in female. In female the smooth area covering entire humeri. Apical border microserrulate.
Aedeagus. Medial lobe slender and elongated (Fig. 14), although minimally wider than in other Conidera species. Endophallic structures (Fig. 17, 20) in an arrangement that is typical for the subgenus. Small stiffening rib with left apex not upcurved, subapically with strong bend; right apex bifid; arciform piece long, distally extremely slender.
Distribution. Recorded from two localities on Mindoro Island. The record from Mindanao based on a single male (matching the holotype very well) requires confirmation.
Comparative notes. The female can be immediately recognized by the aberrant shape of the elytron; this character is less expressed in the male. Besides the characters mentioned in the key below, there are also minor differences in the endophallic structures (comp. Fig. 17–22; white arrows) that support the status of a separate species but should be examined in more specimens. The endophallic structures of C. conicollis are most similar to the new species, except that the small stiffening rib is less bent before its left apex; both species share a bifid right apex of the small stiffening rib and a slender arciform piece. Cylindera mandibularis differs distinctly from both other species of Conidera by a relatively broad arciform piece; in addition, its small stiffening rib has an upcurved left apex and an acute right apex.
