Ceracis tzotzilicus sp. nov. (Coleoptera: Tenebrionoidea: Ciidae) from Guatemala and Mexico.

Ceracis tzotzilicus sp. nov. is described on the basis of 200 specimens collected in San Cristóbal de las Casas (Mexico) and Yepocapa (Guatemala), at an altitude above 2000 m. Ceracis tzotzilicus resembles members of the Ceracis cucullatus species-group due to the fine and sparse pronotal punctation, but males can be distinguished by the absence of a long anterior pronotal lamina and females by the ovipositor lacking gonostyli.

Synopsis of Cis Latreille (Coleoptera: Ciidae) from southern Africa.

A synopsis of the Cis Latreille, 1796 from southern Africa is provided, with the description of 10 new species: Cis bicaesariatus sp. n., Cis foveocephalus sp. n., Cis grobbelaarae sp. n., Cis lacinipennis sp. n., Cis makrosoma sp. n., Cis mpumalangaensis sp. n., Cis parvisetosus sp. n., Cis tessariplacus sp. n., Cis umlalaziensis sp. n. and Cis westerncapensis sp. n. The introduced species Cis fuscipes Mellié, 1849 is recorded for the first time from the Republic of South Africa. New geographic records are provided for the following species: Cis neserorum Souza-Gonçalves & Lopes-Andrade, 2017; Cis regius Orsetti & Lopes-Andrade, 2016 and Cis stalsi Souza-Gonçalves & Lopes-Andrade, 2017. Most southern African Cis are placed in available or newly proposed species-groups and a provisional identification key is provided.

Redescription of Cis renominatus and Paratrichapus javanus (Coleoptera: Ciidae).

 Cis renominatus Sandoval-Gómez, Lopes-Andrade Lawrence, 2014, and Paratrichapus javanus (Pic, 1937) were originally described in the genus Xylographus Mellié, 1847. Their original descriptions are anecdotal and do not provide information on the morphology of male abdominal terminalia, which is essential for accurate identification of ciid beetles. Our aim is to redescribe C. renominatus and P. javanus based on careful examination of lectotypes and paralectotypes, and also on additional specimens of C. renominatus identified by us. The most remarkable feature of C. renominatus is the morphology of male genitalia, with penis about twice as long as tegmen, very slender, subparallel-sided, with apex hook-shaped and base spatula-shaped. Paratrichapus javanus is the largest species of the genus (length at least 3.50 mm) and is characterized by its very expanded and rounded metatibiae that bear about 25 spines, and by the anterocephalic edge of males bearing two tubercles with two tufts of bristles between them.
