NE Thai. 26-30IV. 2006 Takakuwa, M. leg./ 1154 Sericini Asia spec.” (ZFMK).</p><p>Description of the holotype.</p><p>General appearance.</p><p>– Length of body: 7.4 mm;</p><p>– Length of elytra: 5.4 mm;</p><p>– Maximum width: 4.4 mm.</p><p>Dorsal surface reddish brown; surface of labroclypeus and disc of frons glabrous.</p><p>Head. – Labroclypeus subtrapezoidal, wider than long, widest at base, lateral margins moderately convex and convergent to strongly rounded anterior angles, anterior margin weakly sinuate medially, margins moderately reflexed. – Surface weakly convex, moderately shiny, finely and densely punctate. – Frontoclypeal suture indistinctly incised, flat and weakly curved medially. – Ocular canthus short and triangular, impunctate, with a single terminal seta. Smooth area anterior to eye twice as wide as long. – Frons dull,</p><p>Reviewers:</p><p>Denis Keith (France) - ZooBank: http://zoobank.org/ C922B63D-331E-44BF-B386-9A70AE05CA28</p><p>with sparse, fine punctures, with single erect setae beside each eye. – Antenna yellowish, with ten antennomeres; club composed of four antennomeres in male, straight, rarely longer than 1.5 times as the remaining antennomeres combined. – Eyes moderatelysmall,ratio of diameter/interocular width:0.71. – Mentum elevated and slightly flattened anteriorly.</p><p>Thorax. – Pronotum moderately wideandstronglyconvex,lateralmargins evenly convex, more strongly narrowed anteriorly towards sharp and slightly produced anterior angles. – Anterior margin of pronotum slightly convex, with fine complete marginal line. – Posterior angles blunt or strongly rounded. – Surface finely and densely punctate, except minute setae glabrous, lateral and lateral anterior margins sparsely setose. – Hypomeron not carinate. – Scutellum triangular, finely and densely punctate.</p><p>Elytra. – Oblong, widest just behind middle, striae distinctly impressed, finely and moderately densely punctate, intervals distinctly convex, with coarse and dense punctures concentrated along striae, with very minute setae in punctures. – Epipleural edge robust, ending at weakly curved and slightly blunt external apical angle of elytra, epipleura densely setose, apical border with a broad fringe of microtrichomes (100x).</p><p>Ventral. – Surface weakly shiny, finely and densely punctate, metasternum sparsely covered with fine, short, or very minute setae, metacoxa glabrous, with a few single setae laterally. – Abdominal sternites finely and densely punctuate, with a transverse row of coarse punctures, each bearing a robust seta. – Mesosternum between mesocoxae as wide as mesofemur.Ratio of length of metepisternum/metacoxa: 1/1.67. – Pygidium weakly convex and dull, densely punctate, without smooth midline, almost glabrous, but with a few longer setae along apical margin; pygidium without strong sexual dimorphism.</p><p>Legs. – Moderately wide. – Femora finely and sparsely punctate. – Metafemur wide and moderately shiny or dull, anterior margin acute, posterior margin smooth ventrally and only weakly widened in apical half, posterior margin smooth dorsally, with a few short setae basally. Posterior margin of metafemur generally straight or slightly convex. – Metatibia short and wide, ratiowidth/length:1/2.8; basal group of dorsal spines of metatibia at first third of metatibial length. Robust spine at middle of ventral margin extremely prolonged and s-shaped, exceeding distal margin of metatibia. – Tarsomeres with fine, very dense setae ventrally on distal half, neither laterally nor dorsally carinate, dorsally smooth. – Metatarsomeres with a strongly serrated ridge ventrally and glabrous;first metatarsomere slightly shorter than two following tarsomeres combined, one third of its length longer than dorsal tibial spine. – Protibia short, bidentate; anterior claws symmetrical, basal tooth of both claws bluntly truncate at apex.</p><p>Male genitalia. – Aedeagus: Fig. 1A–C.</p><p>Remarks. – Female unknown.</p><p>Diagnosis. – Tetraserica takakuwai sp. nov. is in shape of aedeagus most similar with Tetraserica bansanpakiana Fabrizi, Dalstein &amp; Ahrens, 2019 and T. margheritae Fabrizi, Dalstein &amp; Ahrens, 2019 (Fig. 2).</p><p>It shares with both species:</p><p>- the robust metatibial spine in middle of ventral margin being extremely elongate and s-shaped, exceeding distal margin of metatibia,</p><p>- short median lamina of phallobase,being subequal to at maximum half of length of phallobase,</p><p>- the unicolored dorsal surface,</p><p>- the left paramere being at base simple,and the strongly asymmetric phallobase (dorsal view).</p><p>Tetrasericatakakuwai sp. nov. differs from T. bansanpakiana by:</p><p>- the longer and narrower median lamina of phallobase which does not possess an apical dorsal tooth (Fig. 2A, C),</p><p>- the basal uncleft portion of the left paramere is much longer (Fig. 1A), although if the apical branches appear to be broken in the holotype of T. takakuwai sp. nov.</p><p>From T. margheritae the new species differs by:</p><p>- the dorsoventrally wider median lamina of phallobase whose dorsal margin is weakly convex and not straight as in T. margheritae (Fig. 2E);</p><p>- the left paramere is basally not bent as in T. margheritae (Fig. 2E; lateral view) but straight in basal third (Fig. 1A), and over its length (lateral view) weakly curved instead of straight as in T. margheritae;</p><p>- in dorsal view, the left paramere is in T. takakuwai sp. nov. straight and not curved externally (Fig. 1B) as in T. margheritae (Fig. 2F).</p><p>Etymology. – The new species is named after its collector, M. Takakuwa (nouningenitivesingular).</p></div>	https://treatment.plazi.org/id/8D0987B7D572FFAEFC187E0829FAFDA6	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
