( Figs 6, 7, 8 , 43 , 50 , 66 , 82 , 98 , 114 , 128 )

Caraphia cribrata Gahan, 1906: 75 , fig. 29 (Type locality: "Karen Mts., Burma (current Myanmar)"); Boppe, 1921: 52; Aurivillius, 1912: 177; Hayashi & Villiers, 1985: 24, 25; Chou & N. Ohbayashi, 2008: 139. Caraphia (Caraphia) cribrata: K. Ohbayashi, 1963: 8 .

Diagnosis. Male: BL= 13.4 mm; EW= 3.5 mm. Body mostly dark brown, rather stout. Antennae exceeding elytral apex at the middle of 8th segment; scape short and thick, 2.25 times as long as wide, relative lengths of segments from base to apex: 56: 14: 51: 74: 101: 103: 100: 94: 90: 86: 103.

Pronotum wider than long with sides inflated laterally near middle; disk reticulately sculptured, provided with a pair of protuberance near apical third.

Elytra with disk longitudinally depressed between side and suture from basal third to apical sixth, and forming a weak ridge on apical half; foveae denser on basal sixth, then arranged in rather irregular rows; scales grayish yellow, nearly alternating on rows of foveae, suberect and barely curved with pointed apex, 2.5–2.7 times as long as the diameter of foveae.

Genitalia ( Fig. 114 ) with paramere of tegmen very narrow, 4.17 times as long as basal width, and converging apically with outer side slightly curved, 0.18 times as long as tegmen. Median lobe with dorsal plate almost reaching the apex of ventral plate; basal struts slightly shorter than a half of median lobe. Endophallus ( Fig. 128 ) rather simple and elongate, MPH roundly inflated and with inverted V shaped sclerite near base; APH claviform with a pair of small dorsal projections near base, without rod-like sclerite.

Female: BL= 11.7–14.7 mm. Similar to male in body color, foveae and scales. Antennae not reaching elytral apex, with scape 0.40 times as wide as long, relative lengths of segments from base to apex: 51: 13: 58: 61: 72: 67: 67: 61: 60: 52: 61. Elytra widened apically from humeri to apical fourth (1.15 times as wide as humeral width), then rounded to truncate apices.

Type material examined. Holotype: ♀, Karen Mts., Birmah (current Myanmar), Doherty leg. ( Fry Coll. 1905. 100 ) ( BMNH) .

Other specimens examined. 1♂, Dauna Range, Kayin Sta. (Karen), Myanmar, IV-1992, Local collector leg. ( PCYK); 1♀, Doi Pha Hom Pok, Chiang Mai, N. Thailand, 20°05'N, 99°15'E, 14–23-III-2004, T. Ihle leg. ( PCCH).

Distribution. Myanmar, Thailand.

Remarks. This species can be distinguished from the other species by irregularly arranged foveae of elytra, longitudinally depressed elytral disk with a carina, or slender and pointed elytral scales.

The original Gahan (1906) description of this species was possibly based on a single specimen, or at least just females ("Antennae of female do not quite reach to the apex of the elytra"; male antennae were not described).

Fortunately we could examine a male specimen collected at the type locality through the courtesy of Y. Kusakabe, and we identified it as the male of C. cribrata because of its similar appearance. However the head is narrower than in female, third antennal segment shorter than (longer than scape in female), and also basal width of pronotum is equal to its length (pronotum distinctly wider than long in female).

In addition, one female specimen collected in Thailand was recently received from Carolus Holzschuh which he identified as C. cribrata . However the elytra do not widen apically as in the type specimen though the other structures are very similar. At the moment we cannot decide if the difference is infraspecific variation or not, and further material will be needed.
