03B7C5020941FFACE8FA7C65FD0AF914.taxon	diagnosis	Diagnosis. D. siamicus sp. n. together with D. cylindricollis Kaszab, 1975 from central India lack the lateral margins of the pronotum (see couplet 1 / 2 in the identification key of the Oriental species by Kaszab 1981). All other known Oriental species have distinct lateral margins. However, in D. cylindricollis the elytra are shorter (1.7 x longer than wide), have distinct punctural rows, the head is as long as wide, and the cervix is distinctly separated from the tempora (Kaszab 1975). For a photograph of the holotype of D. cylindricollis see http: // coleocoll. nhmus. hu. The aedeagus of D. cylindricollis is unknown.	en	Schawaller, Wolfgang, Bellersheim, Aron (2022): Two new species of the genus Dichillus Jacquelin du Val, 1861 (Coleoptera: Tenebrionidae: Stenosini) from Thailand.

03B7C5020941FFACE8FA7C65FD0AF914.taxon	discussion	Remarks. Some specimens were mounted by the collector on a card together with ants, so very probably this species can be considered as myrmecophilous.	en	Schawaller, Wolfgang, Bellersheim, Aron (2022): Two new species of the genus Dichillus Jacquelin du Val, 1861 (Coleoptera: Tenebrionidae: Stenosini) from Thailand.

03B7C5020941FFAEE8FA7A47FB4DFB06.taxon	description	Description. Body length 3.2 mm (for measurements of head, pronotum and elytra see Fig. 3). Body and appendages dull redbrown, surface chagreened, elytra blackish. Head as long as wide, widest across genae. Tempora nearly parallel before cervix. Genae arched from posterior margin of eyes to the widest part, there arched and directly narrowed to clypeus. Clypeus medially excavated. Suborbital costa lacking. Head between genae and clypeus with longitudinal impression. Eyes completely divided by genae. Dorsal punctures large, on vertex slightly confluent, towards clypeus diminishing, with fine and short forward-oriented yellow setae; surface on vertex dull, on clypeus shining. Antennae short and extremely broad, shape of antennomeres as in Fig. 3, antennomere three 1.5 x longer than antennomere two, antennomeres 1 – 9 with dull surface, antennomeres 10 and 11 with shining surface and with longer yellow setae. Pronotum cordiform, 1.35 x longer than wide, widest shortly before anterior angles, lateral margins parallel in basal third; anterior angles rounded, not protruding; posterior angles rectangular; anterior and posterior margins straight, lateral margins without distinct dentation, not beaded. Pronotal disc medially with weak longitudinal impression. Punctures dense and large as on vertex, but not confluent, with adpressed yellow setae as on head. Prosternal apophysis bent down. Elytra convex and round-oval, widest across middle, 1.3 x longer than wide, with 10 rows of punctures, size of punctures similar to those on pronotum, but more separate, punctures with adjected microsetae. Alternate intervals 3, 5, 7 and 9 with weak tuberculated costae; costae with short but erect yellow setae pointing backwards. Humeral angles without teeth and completely absent. Upper margin of epipleura sharp, epipleura in posterior part with one row of punctures (Fig. 4). Legs covered with fine light adherent hairs. Abdominal ventrites with small punctures with fine setae, punctures of last ventrite slightly denser and smaller, surface of last ventrite lighter than of basal ventrites (Fig. 4).

03B7C5020941FFAEE8FA7A47FB4DFB06.taxon	diagnosis	Diagnosis. D. grimmi sp. n. can be recognised among all Oriental species by the extremely broad antennae, by the convex and round elytra without humeral teeth (except in D. siamicus sp. n.), by the alternate elytral intervals with weak tuberculated costae with erect setation, and by the sharp upper margin of epipleura. In the key to the Oriental species by Kaszab (1981), D. grimmi sp. n. runs to the last couplet 27 / 28 (D. chujoi Kaszab, 1966 and D. longicollis Kaszab, 1981). However, both species are smaller (2 – 2.6 mm), have longer and narrow antennae, long elongate and flat elytra without distinct setation and without costae in the intervals 3, 5 (aedeagi unknown). For a photograph of a paratype of D. chujoi see http: // coleocoll. nhmus. hu. According to Kaszab (1981), all Oriental species (4) with extremely thick antennae as in D. grimmi sp. n. possess distinct humeral teeth, and are distributed more western in Pakistan, Baluchistan, Kashmir and northern India.	en	Schawaller, Wolfgang, Bellersheim, Aron (2022): Two new species of the genus Dichillus Jacquelin du Val, 1861 (Coleoptera: Tenebrionidae: Stenosini) from Thailand.
