 Description. Integument shining, dark-brown; parts of the head, mandibles, scape, margins of the pronotum, epipleura and elytral suture, and parts of the legs blackish.   
Male (Fig. 413). Dorsal face of head, on the gibbosities, coarsely and moderately abundantly punctate; longitudinal depression between gibbosities smooth; area behind gibbosities with transverse region almost smooth, interrupted in middle by punctures as coarse as on the gibbosities, and with the same kind of punctures, somewhat sparse, between that region and the occiput; area between gibbosities and ocular carina distinctly depressed, and with some punctures at anterior part of that depression; area behind the area depressed, coarsely punctate (punctures partially confluent); area behind the eyes coarsely and sparsely punctate; ocular carina elevated, distinctly bifurcated in “Y” near the posterior edge of the eyes (Fig. 413); punctation behind bifurcation of ocular carina coarse and anastomosed. Eyes (Fig. 95) moderately narrow; posterior ocular edge (Fig. 413) distinct. Central area of clypeus almost vertical close to the front. Central projection of labrum (Fig. 34) wide, truncate at apex, and with a small triangular projection in its middle. Submentum depressed from middle to anterior edge; punctation moderately coarse and sparse; pilosity short and sparse (longer and more abundant towards anterior edge); anterior edge elevated throughout, more distinctly laterally. Mandibles approximately as long as head; teeth of inner margin (Fig. 156) placed around middle. Antennae reaching posterior angles of prothorax; ventral sensorial area of antennomeres III-XI not visible from side (Fig. 235), and not divided by carina; dorsal sensorial area of antennomere XI moderately small, narrow and elliptical.  
Lateral margins of prothorax subparallel at anterior two-thirds towards anterior angles. Pronotum moderately finely and abundantly punctate at central region, gradually coarser laterally, mainly close to anterior angles; lateral area microsculptured, more distinctly close to anterior angles; anterior edge sinuous; anterior angles slightly projected forward; lateral angles not marked; posterior angles well marked. Basal two-thirds of elytra coarsely, abundantly punctate, mainly laterally on basal third and across medial third; punctation of apical third just finer, more abundant and concentrated; each elytron with two carinae well marked. Metasternum with punctures just coarse, moderately abundant laterally, gradually finer and sparser towards the metasternal suture. Metafemur moderately short. Dorsal face of metatibia slightly rounded at basal half, and slightly sulcate at apical half; in dorsal view moderately wide. Metatarsomere V (without claws) slightly longer than I-III together (Fig. 278); in dorsal view (Fig. 301) distinctly enlarged at basal half.  
Male genitalia: median lobe long, forming a flattened tube, with two elongate struts at base, apex widely rounded and distinctly incised at middle (Fig. 307); parameres long, forming a ring, with a pair of pointed processes, separate near their base in dorsal view, apical lobes short and wide, stout relatively wide (Fig. 306).  
Female (Fig. 415). Head moderately narrow; dorsal face coarsely and abundantly punctate throughout. Central projection of labrum (Fig. 35) narrow and rounded at apex. Mandible (Fig. 157). Pronotum with punctation as in male, but microsculptured lateral area not evident; anterior angles more projected than in male; anterior edge sinuous. Antennae almost reaching posterior angles of prothorax. Metafemur (Fig. 414) moderately short.  
 Variability. Male and female: elytral carinae visible.   
 Dimensions in mm (M / F). Total length (including mandibles), 15.9-22.2/21.7; prothorax: length, 3.9- 4.6/4.4; anterior width, 4.6-5.8/5.6; posterior width, 3.8-4.5/4.7; humeral width, 4.6-6.0/6.3; elytral length, 10.4-12.6/13.5.   
 Geographical distribution. Taiwan.   
 Material examined. TAIWAN, Kaohsiung: Liukuei, M, IX.27.1984, W. L. Chen coll. (HNCO); Mount Chuyunshan, M, VI.5.1999, Chen Changging coll. (CCCO); M, V.2000, WenShing Lim coll. (NOCO); Shanping, M, X.15.1988, C. L. Cen coll. (HNCO); Taiyuan-shan, M, VIII.10.1987, W. C. Raw coll. (HNCO). Nantou: Puli, M, (ex-Collection Hajime Yokoyama), V.1.1973 (OMNH). Specimen examined through photographs taken by Dr. Mei-Ling Chan (NMNS): TAIWAN, Kaohsiung: Shanping, F, 6-VII-1997, Z. A. Liao coll. (NMNS).   
 Types, type-localities. Two female syntypes from Taiwan (Bandaisya near Musya). Gressitt (1951) stated that Mitono’s Collection is deposited at TARI. However, Dr. Chi-Feng Lee (personal comm.) stated that he has not found the types of this species at TARI.   
 Comments. Miwa and Mitono (1939) recorded: “It may be regarded that this species agrees with the one reported from Formosa as P. janus, by A. Lameere”. However, Lameere (1902), when redescribing the species that he incorrectly believed to be P. janus, did not record it from Taiwan: “…provenant de la Nouvelle-Guinée occidentale (Hatam et Andai) et de Ternate, et ceux de Java …Bates la cite encore de Célèbes et van Lansberge de Céram”. It was only in Lameere (1912) that that author recorded Taiwan as a distribution area for P. janus: “M. Boppe m’en a communiqué um exemplaire de Formose”. Besides, Parandra janus sensu Lameere (1902) is not the species described by Bates, but instead, K. javana. Therefore, the redescription presented by that author does not correspond to K. janus or K. formosana. We believe that it is incorrect to affirm that K. formosana agrees with the species redescribed by Lameere (1902, 1912), although, probably, the species from Taiwan examined by Lameere corresponded to K. formosana.   
 Hayashi (1963) was the first to record Parandra formosana from the Ryukyu Islands based on a male from Omotodake (Ishigaki Island, Yayeyama Islands). We believe that K. formosana does not occur in the Ryukyu Islands, and that Hayashi was actually examining K. uenoi. Thus, K. formosana should be excluded from the Japanese fauna. Apparently, the misidentification of the male from the Ryukyu Islands is based on the elytral carinae that are well marked in both K. formosana and K. uenoi. The authors believe the distribution of K. formosana is restricted to Taiwan.   
 Samuelson and Gressitt (1965) followed the opinion of Hayashi (1963), and recorded K. formosana from “Ryukyus (Ishigaki)”. The key presented by those authors, to separate the species known from the Ryukyu Islands, correctly separates K. shibatai from K. uenoi (incorrectly pointed out as K. formosana).   
 Komiyandra formosana differs from K. uenoi, mainly by the: head of female proportionally larger (Fig. 415); central projection of labrum of female narrow and rounded at apex (Fig. 35); metatibiae distinctly wider in dorsal view; metatarsomere V distinctly enlarged at basal half (Fig. 301). In K. uenoi, the head of female is proportionally smaller (Fig. 480), central projection of labrum of female is truncate at apex (Fig. 73), metatibiae are narrow in dorsal view, and metatarsomere V is not enlarged at basal half (Fig. 303).
