( Figs. 23 , 41a–c , 53 , 65 ) Peltonotus peninsularis Miyake 2000: 113–115 , 118. Miyake (2000) described ten new speciesgroup taxa. Article 16.4 (ICZN 1999) states that all species published after 1999 must be accompanied by: (1) the explicit fixation of a holotype or syntypes and (2) a statement of intent that specimens will be (or are) deposited in a collection. Peltonotus peninsularis is an unavailable name for two reasons. First, Miyake neglected to designate/denote a holotype or syntype (s) in his description. He did not include locality data or the number of specimens in the type series. Thus, the requirement of explicit fixation of a holotype or syntype is not fulfilled. Second, Miyake noted (2000: 105) that “the greater part of holotypes and paratypes , described in this paper are preserve (sic) in the Research Institute of Evolutionary Biology.” Although vague, this statement could be interpreted to fulfill the requirement of a statement of intent regarding the deposition of the type specimen. However, we were unable to locate the holotype for this taxon at RIEB; we found only seven paratypes . Thus, the requirement that a statement of type deposition is not fulfilled. Based on both of these oversights, the name is unavailable. Unavailable name . Type Material.

Maxilla: mala with dense lamellate setal brush; stipes with setae dense, long, flattened at apex, not curled at apex; palpomere 2 with weak internomedial bump. Antennal club subequal to segments 2–7. Pronotum: Bead lacking anterior to scutellum. Surface moderately densely punctate; punctures simple, multisetigerous laterally; setae minute (1–7 per puncture) and short (0–1 per puncture). Lateral margin lacking long setae. Elytral sutural length: About 4.5 times length of scutellum. Elytra: Surface with 7 poorly developed, punctate, longitudinal striae between suture and humerus; punctures ocellate, moderate in size, moderately dense, multisetigerous apically and laterally; setae minute (1–20+ per puncture). Intervals similarly sculptured. Propygidium: Surface shagreened and moderately densely punctate; punctures simple, unisetigerous, with a transverse row near apex; setae short, rufous. Pygidium: Surface densely punctate; punctures ocellate, multisetigerous; setae minute (7–12+ per puncture) and short (0–1 per puncture). Venter: Prosternal keel elongate; apex projecting anteriorly at about 90° with respect to ventral plane, produced to about 3/4 of protrochanter, truncate. Legs: Foretibia of male bidentate; lateral margin with short, dense setae. Foretarsomere 5 subequal in length to tarsomeres 1–4, greatly thickened; foretarsomeres 3–4 with apices expanded, dorsal and ventral apices of tarsomeres 1–4 clothed with small patch of dense, short setae. Foreclaws of male with inner claw broadly curved, about 5 times thicker than outer claw; outer claw elongate­arcuate, about 1/2 the length of inner claw; empodium bulbous at base. Meso­ and metatibial claws of male with 2 setae, claw angled toward venter, about 3/4 length of metatarsomere 5. Metatibia of male with apical spurs weakly curved; ventral spur produced to middle of metatarsomere 1, dorsal spur produced to apex of metatarsomere 1. Parameres: Fig. 41a–c . Allotype Female. Differs from the holotype in the following respects. Length 17.6 mm . Widest width 8.9 mm .

Surface of clypeus with setae minute (1–12+ per puncture). Pronotum: Punctures lacking setae. Elytron: Epipleuron of female in ventral view expanded, broadly incised at sternite 4; in dorsal view expansion well­developed ( Fig. 53 ). Legs: Foreclaws 1/2 length of foretarsomere 5, claw angled toward venter. Paratypes ( 6 males , 5 females ). Differ from the holotype and allotype in the following respects. Length 16.3–17.4 mm . Widest width 8.2–8.3 mm . Leg: Metatibial ventral spur produced to middle of metatarsomere 1, dorsal spur produced to middle of metatarsomere 1. Etymology. The specific epithet “ podocrassus ” refers to the greatly enlarged fifth foretarsomere in the male ( podus = foot, crassus = stout, thick). This is compared with males of P. gracilipodus , the sister species, in which the males have a slender fifth foretarsomere. Diagnosis. Males of P. podocrassus are easily separated from other species of Peltonotus based on the metatibial spur that is subequal or slightly longer than metatarsomere 1 (the metatibial spur is usually subequal in length to metatarsomeres 1–2). Peltonotus podocrassus closely resembles P. sisyrus and P. gracilipodus . Peltonotus podocrassus differs from P. gracilipodus by the form of the fifth foretarsomere in the male (robust in P. podocrassus , slender in P. gracilipodus ), palpomere 2 of the mentum that lacks curled setae, and palpomere 2 of mala that lacks curled setae. Peltonotus podocrassus differs from P. sisyrus based on the rounded apex of the mentum (triangular in P. sisyrus ) and the length of the metatibial spur (subequal to metatarsomeres 1–2). Distribution ( Fig. 65 ). Peninsular Malaysia . Locality records ( 13 specimens ) from WADA , MLJC , ZMHB , RIEB . PENINSULAR MALAYSIA . Perak State (1): Kwala Kangsa. Pahang State (11): Cameron Highlands, Gunong Jasar, Tanah Rata, Tapah ( 39 mi from). No Data (1). Temporal Data. March (5), April (7). Remarks. In addition to neglecting to fulfill the requirements for species­group names in Article 16.4 (ICZN 1999; see above), Miyake’s (2000) invalid description of P. peninsularis did not include locality data and did not indicate the number of specimens in the type series. Because other descriptions of new species in Miyike’s publication fulfilled the requirements of Article 16.4, we believe that it was simply an oversight in the case of P. peninsularis .
