背笔石科包括一个属，背笔石Gunther，和五个命名种，分布于澳大利亚北方和新几内亚南部。形态学证据将背笔石属归类于棘斜类（Acanthoplesiopids）（下唇有连续的游离边缘;头部裸露;背鳍和臀鳍有许多刺和很少的分节鳍条;没有固有伸肌;尾鳍鳍条数量减少），并支持与Acanthoplesiops的姐妹关系（下唇上有联合皮瓣;减少的下骨5;减少的下骨突）。这一假说解决了Acanthoplesiops内的关系，澄清了极性的自体中间桡的背鳍和臀鳍peprophores。建议的棘斜亚科之间的关系是：棘斜亚科（Belonepalipon）（Beliops（Notograptus）（Acanthoplesiops hiatti（A. indicus（A. psilogaster（A. echinatus））））））。背笔石属的分布与它的姐妹分支相一致，因为在澳大利亚北方或新几内亚南部还不知道Acanthoplexiops。在几个群体中有重复的地理模式，这表明澳大利亚是更广泛的印度太平洋地区的基底区。Congrogadinae（Pseudochromidae）和Notograptus之间的相似性早已被注意到，两者都有松散连接的悬骨和细长的身体，这被错误地认为是关系的指标;我们增加了减少的鳃弓，直，管状肠道和高度可扩张的肛门。我们研究这些相似之处，作为一个共同的专门的食性的指示。背笔石是一种捕食虾的掠食者，能够吞下它的大型猎物。大多数种类的congrogadines吃整个，大甲壳类动物。这可能是一个对特定选择性制度的趋同适应的例子。© 2004年伦敦林奈学会，林奈学会动物学杂志，2004年，141，179-205。
The Notograptidae contains one genus, Notograptus Gunther, and five nominal species from northern Australia and southern New Guinea. Morphological evidence places Notograptus among acanthoclinine plesiopids (continuous free margin of lower lip; head naked; dorsal and anal fins with many spines and few segmented rays; no extensor proprius; reduced number of caudal-fin rays) and supports a sister relationship with Acanthoplesiops (symphyseal flap on lower lip; reduced hypural 5; reduced hypurapophysis). This hypothesis resolves the relationships within Acanthoplesiops, clarifying the polarity of autogenous middle radials of dorsal- and anal-fin pterygiophores. The proposed relationships among acanthoclinines are: Acanthoclinus (Belonepterygion (Beliops (Notograptus (Acanthoplesiops hiatti (A. indicus (A. psilogaster (A. echinatus))))))). The distribution of Notograptus compliments that of its proposed sister clade in that Acanthoplesiops is unknown from northern Australia or southern New Guinea. There are repeated geographical patterns among several groups suggesting that Australia is a basal area to a broader Indo-Pacific region. Similarity between the Congrogadinae (Pseudochromidae) and Notograptus has long been noted, both having a loosely connected suspensorium and elongate body which were mistakenly considered indicators of relationship; we add reduced branchial arches, straight, tube-like gut and highly expandable anus. We examine these similarities as an indication of a shared specialized feeding habit. Notograptus is an alpheid shrimp predator, able to swallow its large prey whole. Most species of congrogadines eat whole, large crustaceans. This is probably an example of convergent adaptation to a particular selective regime. © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society, 2004, 141, 179–205.
