Material examined here is deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC). Dry specimens were used for the observation, description and illustration. Genital segments of the examined specimens were macerated in boiling solution of 10% NaOH and drawn from preparations in glycerin jelly under a Leica MZ12.5 stereomicroscope. Color pictures for adult habitus were obtained by a KEYENCE VHX-1000 system. Illustrations were scanned with Canon Cano Scan LiDE 200 and imported into Adobe Photoshop CS6 for labeling and plate composition. Terminology of morphology, genital characters and measurements follow

This species is similar to Doryphorina subdeflexa but can be distinguished from the later by phallobase with 2 pairs of apical membranous lobes, dorsal apical lobes (Fig. 19) long and slender, with 3 long spines at base (dorsal part with two pairs of dorsolateral apical lobes directed laterally, with 2–3 long apical spines in dorsal view in Doryphorina subdeflexa).
This new species is derived from the Greek word “conglobatus”, which indicate that the apical lobes of phallobase are connected.

Holotype ♂, China: Guizhou, Congjiang, 24 Jul. 2005, coll. Deyan Ge. Paratype, 1♂, China: Guizhou, Libo, Aug. 1997, coll. Zizhong Li (both in GUGC).

This species is similar to Doryphorina minor, but can be distinguished from the later by phallobase ventral lobes (Fig. 31) with 2 pairs of apical lobes connected, not produced laterally, apex and base with about 16–19 long spines totally in ventral view (ventral part with two pairs of V-shaped elongate apical lobes, directed laterally and ventrally, each with 4–5 long spines in ventral view in Doryphorina minor).
This new species name refers to the type locality, Guizhou Province.
Doryphorina conglobatus sp. n. is similar to Doryphorina subdeflexa but can be distinguished from the later by phallobase lobes; Doryphorina guizhouensis sp. n. is similar to Doryphorina minor and Doryphorina stali but can be distinguished from Doryphorina minor by phallobase ventral lobes (Fig. 31); and can be distinguish from Doryphorina stali by phallobase dorsal lobes (Fig. 32); Doryphorina conglobatus sp. n. can be distinguished from Doryphorina guizhouensis sp. n. and Doryphorina minor, Doryphorina stali by the relatively robust cephalic process; the forewings without dull ochraceous spot near stigma. So, external features and phallobase lobes play an important role to identify of all male species in the genus.
The new species and all described species all distributed Oriental region. So far, this genus belongs to Oriental region.
