Luciola nr. laticollis

形態特徵：體長5.0-6.5毫米。前胸背板前方中部有大黑斑，黑斑大小和深淺有個體差異; 雄螢發光器位於整個第6腹板和第7腹板。雌螢與雄螢外表近似，複眼較細小，發光器位於整個第6腹板。與擬紋螢近似，但本種較細小，沒有淺色鞘翅邊緣，發光模式是簡單脈沖式。

分佈地點：梧桐寨河谷、大埔滘、大帽山。

成蟲活躍月份：5-6月

其他資料：成蟲在茂盛的樹林內活動，有時百計成蟲在同一地點同時出現。本種與 Luciola laticollis 的原始描述不完全吻合，主要是本種沒有淺色鞘翅邊緣。另外，根據原始描述，Luciola robusticeps 亦與Luciola laticollis很近似，但兩種的模式標本均未被找到，無法作準確判斷。

Morphological features：Body length 5.0-6.5 mm, a large black mark at the middle of pronotum anterior region, size and darkness of the mark varies across individuals; light organs occupying ventrite 6 & 7 in male; only ventrite 6 in female. Female resembles male, but with smaller compound eyes. Close to Luciola curtithorax, but smaller in body size, without light colour elytra rim and flash pattern is simple pulsation.

Distribution：Ng Tung Chai Valley, Tai Po Kau, Tai Mo Shan.

Adult flight period：May to June.

Other information：Adults are found at dense woodlands, sometimes hundreds of individuals appear at the same time. This species does not match well with the original description of Luciola laticollis, this species is smaller in size, lacking the light colour elytra rim. According to the original description, Luciola robusticeps is also similar. However, type specimen of both species are not found. Clear judgement cannot be made.
