Short description
সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
পৃষ্ঠীয় কাঁটা (মোট ) : 2; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 6; পায়ূর নরম পাখনা্তুন্ড: 11 - 13; কশেরুকা : 43. Distinguished by the following combination of characters: small dots irregularly placed (forming 8-9 rows) and most developed in the anterior two thirds of body; the mouth with thick striated lips; an enlarged posterior branch of the dorsal premaxillary process synchondrally articulated with the lateroanterior margin of mesethmoid; a right-angled posterolateral margin of mesethmoid; the exposed centra of the 7th vertebrae; and a large pharyngobranchial 3 with a well developed dorsal crest. Differs from P. fur in possessing more gill rakers on the first arch (19-22 vs. 16-18) and a wider mouth (32.0-35.1% HL vs. 24.6--30); and from P. absconditus in having a larger interorbital distance (22.2-29.2% HL vs. 18.6-22.7), a relatively smaller ratio between orbital diameter and interorbital width (70.8-115.0 vs. 104.1-148.9); a shallower body (19.0-24.5% SL vs. 21.6-26.9), a shorter head (25.8-28.9% SL vs. 27.5-30.8), a smaller predorsal length (36.2-39.9% SL vs. 38.7-42.9) and a smaller prepelvic length (47.4-51.0% SL vs. 49.3-53.1). Vomerine tooth plates occasionally develop in P. heroldi while they are always present in P. absconditus and absent in P. fur (Ref. 41259).
