Deltochilum abdominale Martinez 1947

Deltochilum abdominale Martínez, 1947 Fig. 28A Deltochilum abdominalis [sic] Martínez, 1947a: 269 (original description). Type locality: Venezuela: Distrito Capital: Pico Naiguatá. Name-bearing type: holotype (MACN), examined by MC. Note: as explained by Harold (1869d), the genus-group name Deltochilum is formed from the combination of the Ancient Greek nouns δέλτᾰ (‘ délta ’), the name for the fourth letter in the Ancient Greek alphabet (Δ) and, by extension, used to refer to anything shaped like that letter, and χεῖλος (‘ kheîlos ’), meaning ‘lip’, ‘mouth’, in reference to the labrum of the single species originally assigned to the genus, a structure that Eschscholtz (1822) described as being “cordiform” (i.e., heart-shaped, or an inverted letter delta). Since, in his Latinisation of the new name, Eschscholtz changed the ending of ‘ kheîlos ’ to ‘ - um ’, a neuter suffix in Latin, to render ‘ - chilum ’, the noun Deltochilum, too, is to be regarded as neuter in gender in accordance with Article 30.1.3 of the Code (ICZN 1999). Latin or Latinised adjectival specific and subspecific names combined with it must, therefore, be declined accordingly (Article 31.2). Martínez (1947a), however, formed the binomen originally as Deltochilum abdominalis, with the two-termination New Latin adjective used as the specific name ‒ meaning ‘abdominal’ ‒ incorrectly declined in the masculine/feminine. We fix this in the heading above by declining the name in the neuter; i.e., by replacing the desinence ‘- is ’ with ‘- e ’ as grammatically required.
