Differential diagnosis
Cautires obsoletus differs from the other Javanese species in the black pronotum (Fig. 8) and a very oblique border between the bright and dark parts of elytra (Fig. 6). The basal part of elytra is brown to reddish brown and differs from the brightly orange coloration of the other species in Java.
Redescription
.Male. Body small to medium-sized, dorso-ventrally flattened, slender; head, body, posterior half of elytra and appendages dark-brown to black; basal half of elytra brown to reddish brown (Fig. 6), body covered with dense pubescence. Head small, partly hidden in pronotum, clypeus slightly concave, labrum simply rounded, mandibles slender, strongly curved, maxillary palpi slender, apical palpomere pointed; labial palpi similar in shape. Eyes small, hemispherically prominent, their frontal interocular distance 1.15 times eye diameter. Antennae shortly flabellate, 11-segmented, covered with short, dark colored setae (Fig. 20). Pronotum flat, only slightly transverse, 1.15 times wider at base than length at midline; frontal margin projected forward; lateral margins slightly elevated, concave, posterior angles acutely projected, pronotum with moderately wide median areola, attached to middle of basal margin of pronotum, connected to anterior margin by keel occupying one third of midline, lateral keels absent (Fig. 8). Elytra flat, with well developed four primary longitudinal costae; secondary costae considerably weaker, cells regular, mostly slightly longitudinal. Legs laterally flattened, covered with dark colored setae. Male genitalia with phallus widest at midlength and gradually narrowed to apex (Figs 12–13). Female. Body medium-sized, antennae serrate, ovipositor with short valvifers.
Measurements
BL 6.45 mm, PL 1.01 mm, PW 1.36 mm, HW 1.47 mm, Edist 0.51 mm, Ediam 0.44 mm.
Distribution
Cautires obsoletus is known only from several localities in Western Java.
Material examined
2 males, 1 female, Indonesia, W. Java, Puncak Pass nr Bogor, 23. Mar. 1992, H. Arimoto, lgt.; male, [Indonesia] West Java, Puncak Pass, 22. Mar. 1993, Y. Miyake leg. (KMTC, LMBC).
Remark
The holotype of Cautires obsoletus is a strongly damaged female with only a part of one elytron preserved. The basal part of the elytron is testaceous and the loss of reddish coloration may be caused by long-term exposure to light. The holotype of Cautires lineatus is also a female and it differs only in the darker hue of the bright part of the elytra, but it resembles the holotype of Cautires obsoletus in its body shape. The female genitalia of all available specimens are very similar.Holotypes of four other species are males and they do not differ in comparable characters such as body shape and color pattern. Therefore, all these species are considered junior subjective synonyms of Cautires obsoletus.
