Description of Divulgoatus Opitz , new genus

Type species. Pelonium discrepans Gorham 1892: 745 . By present designation.

Diagnosis. In both species of this genus the male capitulum is extremely extended. Moreover, the 8th and 9th capitular antennomeres are highly lobate in male specimens.

Description. Size: Length 6.0–10.0 mm; width 1.5–2.5 mm. Form: Oblong rectangular, body not deep, about 7.5 times longer than broad. Vestiture: Dorsum profusely vested with very short pubescence; antennal funicle highly setose; elytra abundantly vested with minute setae, all setae emerge from minute punctures. Head: Cranium quadrate, frons narrow; gula (Fig, 7) narrowed then widened, gula with two well-developed setose gular processes; labrum ( Fig. 6 ) very shallow, broadly incised distally; mandible ( Fig. 8 ) body stout, anterior dens blunt, medial and posterior dens well developed, penicillus well developed; maxilla laterolacinia present, terminal palpomere subsecuriform; labium narrowed, ligula deeply incised, ligular lobes not narrowed, terminal palpomere subsecuriform; eyes, ommatidia large, ocular notch deep; antenna ( Fig. 4, 5 ) comprised of 10 antennomeres, 8th and 9th with collateral lobes, antennomere very 10 long. Thorax: Pronotum ( Fig. 12 ) slightly transverse, dorsolateral carina complete, disc convex and finely punctate, side margins convex; prointercoxal process ( Fig. 13 ) trigonal; pronotal projections short, acuminate, not approximating prointercoxal process; elytron ( Fig. 11 ) profusely sculptured with small densely scattered setiferous punctations, asetiferous punctations obscure, somewhat cribrate, epipleural fold not abruptly narrowed at elytral middle, slightly deflexed and narrowly extended to elytral apex, elytral anterior margin not carinate; metathoracic wing, wedge open; metendosternite ( Fig. 13 ) with furcal lamina, furcal anterior plate small, subrectangulate; legs, profemora not swollen, tibial ( Fig. 10 ) spur formula 0-2-2, tarsal sole formula 2-2-2, unguis ( Fig. 9 ) without basal denticle. Abdomen: Aedeagus shorter than length of abdomen, distal region of phallobase not bilobed, tegmen reduced ventrally, submembranous, phallobasic struts not confluent with phallobasic apodeme, phallobasic rod present; phallus acuminate distally, phallic plates very narrow.

Distribution. The distribution of this genus extends from India to Myanmar and the Philippines.

Etymology. Divulgoatus is a Latin name with a meaning of “spread”. The gender is masculine.
