Correction of existing generic and species concepts in Platyceroidini (Coleoptera: Lucanidae: Lucaninae) and the description of four new species of Platyceroides Benesh Author Paulsen, M. J. text Zootaxa 2017 4269 3 346 378 journal article 32994 10.11646/zootaxa.4269.3.2 cb56b0e3-1b88-4a89-b478-186e2b30721f 1175-5326 582450 0D7EC140-F88A-49BB-BB62-D2AC8EC6FC1D Platyceroides ( Praocerus ) latus (Fall) , new combination Platycerus latus Fall, 1901 : 291 , original combination. Type series. Lectotype female, here designated (MCZ) labeled: a) “Placer / Co. CAL”; b) “Collected by / Dr. E.C. Van Dyke”; c) “TYPE”; d) “H.C. Fall / Collection”; e) on red paper, “M.C.Z. / Type / 24740”; f) red bordered, handwritten “ Platycerus / latus / Fall”; g) “[ Platyceroides / latus / (Fall)]” / Det. / N.E. Woodley 1983”; h) on red paper, “ Platycerus / latus Fall / LECTOTYPE”; i) “ Platyceroides latus / ( Fall, 1901 ) / det. M.J. Paulsen 2013”. Paralectotype male (MCZ) labeled: a–c) as a, b, and d of lectotype. Two paralectotype females (CASC) labeled: a) “Placer / Co. CAL”; b) “Van Dyke / Collection”. One paralectotype male (CASC) labeled: a) “Placer / Co. CAL”; b) “Van Dyke / Collection”; c) black bordered, handwritten “ Platycerus / latus / Fall”. Female paralectotype (CASC) labeled: a) “Alameda / CO. CAL”; b) “Van Dyke / Collection”. All paralectotypes labeled, on yellow paper: “ Platycerus / latus Fall / PARALECTOTYPE”. The Alameda female paralectotype has suspect data—all other specimens are from the Sierra Nevadas , where the range is extensive. All other Platyceroides specimens examined from Alameda County are P. thoracicus . I do not consider P. latus to occur in Alameda County . One male and three females from the original type series were not located. Distribution ( Fig. 31 ). CALIFORNIA : ALPINE: Alpine Lake; Bloods Meadow. AMADOR: Ham’s Station; “Ten Rise”.

TUOLUMNE: Confidence; Strawberry. YUBA: Bullards Bar; Challenge; Woodleaf. Remarks. This species has the largest distribution in the genus. Females of P. latus are the most easily recognized females in the genus due to the thickened anterior margin of the head ( Fig. 21 ), which is also present in males ( Fig. 15 A). The flagellum of the male genitalia ends in a large, sclerotized club ( Fig. 15 B).
