Diagnosis

Male resembling P. coerulescens with blue markings on head, thorax, abdomen, appendages. Male easily distinguished from P. coerulescens by markings of abdomen tip: small blue dot on S9 and S10 blue on dorsum (Fig. 3 G–H) while S8–10 largely blue in P. coerulescens (Fig. 3 A–B). Female very similar to male in body colouration, including green tones ventrally; antehumeral stripes narrow (Fig. F). Structure, shape of female posterior pronotal lobe of prothorax similar in these species but lobes converging, enclosing roundish space, in P. hoffmanni (Fig. 5F), not converging, enclosing semicircular space, in P. doisuthepensis (Fig. 5C).

Remarks

This species was described from Mondulkiri Province in Cambodia close to the border of Vietnam (Kosterin 2015) and has been recorded from Lam Dong and Dong Nai Provinces of South Vietnam (Kosterin 2016). Yokoi & Souphanthong (2014) provided colourful photos of two bluish Prodasineura

species in Laos that resemble P. hoffmanni ( Prodasineura sp.1 and sp. 2 in Yokoi & Souphanthong 2014: 34). Therefore, it is likely that P. hoffmanni occurs in Laos as well.

Distribution

Vietnam (Fig. 17): Kon Tum (Kon Plong District), Dak Lak (Chu Yang Sin National Park), Dak Nong (Nam Nung Nature Reserve), Lam Dong (Bao Loc District and Da Lat) and Dong Nai (Cat Tien National Park) Provinces (Kompier 2019; Kosterin 2016; this study).
